1. Scope of the Mandate
El Salvador’s e-invoicing framework, known locally as the Documento Tributario Electrónico (DTE) system, mandates the electronic issuance and reporting of tax documents for a broad range of transactions. In general, all transactions subject to VAT in El Salvador must be invoiced electronically and reported to the tax authority’s platform in real time. Key points on the scope and coverage include:
El Salvador’s e-invoicing framework, known locally as the Documento Tributario Electrónico (DTE) system, mandates the electronic issuance and reporting of tax documents for a broad range of transactions. In general, all transactions subject to VAT in El Salvador must be invoiced electronically and reported to the tax authority’s platform in real time. Key points on the scope and coverage include:
-
E-Invoicing & E-Reporting Obligations: El Salvador has adopted a clearance model for e-invoicing. This means every invoice (and certain related tax documents) must be generated in a structured digital format (local JSON schema), digitally signed with a government-issued certificate, and transmitted electronically to the tax authority’s central platform (DGII/MH) for validation. Each transmitted DTE receives a unique “receipt stamp” (Sello de Recepción) upon approval by the tax authority, confirming that it meets all requirements. Only after obtaining this clearance can the e-invoice be considered legally issued and delivered to the customer. In practice, the clearance process itself serves as an e-reporting mechanism, since transactional data is sent to the tax authority in real time for every invoice. There is no separate periodic “e-report” for these transactions – compliance is achieved through the timely electronic transmission of each DTE. (Businesses must still submit routine tax filings like VAT returns and other tax forms, but these are increasingly being pre-populated with data from DTE submissions – see Section 11.)

Domestic B2B Transactions (Business-to-Business): Electronic invoicing is mandatory for B2B supplies. In practice, when a VAT-registered business sells to another VAT-registered business, it must issue a Comprobante de Crédito Fiscal Electrónico (CCFE) – essentially an electronic tax credit invoice that enables the buyer to claim input VAT credit. The CCFE is one of the authorized DTE types and contains all required information (buyer and seller tax IDs, item details, tax breakdowns, etc.), and it must be transmitted to the tax authority’s platform for validation and stamping in the same way as any other DTE. The obligation for businesses to issue valid invoices (now DTEs) for every taxable sale is longstanding – failure to do so can result in severe penalties (a fine of 50% of the transaction amount, with a minimum of two monthly minimum wages, per invoice omitted).

-
Domestic B2C Transactions (Business-to-Consumer): E-invoicing is also required for B2C transactions (sales to consumers). Businesses must issue a simplified electronic invoice (commonly referred to as an “electronic ticket” or e-ticket) to document sales to final consumers. As of January 1, 2025, all taxpayers already in the e-invoicing system are required to issue only electronic consumer invoices (e-tickets) for B2C sales, replacing traditional paper receipts. The Factura Electrónica (FE) is the standard DTE format for B2C transactions (sales to individuals/consumers who do not provide a Tax ID). Like B2B invoices, B2C e-tickets must be generated in the prescribed JSON format, digitally signed, and cleared through the tax authority’s system in real time. Notably, if a consumer does not request a tax-registered invoice (e.g. the sale is below certain thresholds or not needed for tax deductions), the invoice can still be issued as a simplified e-ticket with minimal buyer information. Recent legislative changes (Decree No. 94 of 2024) clarified that consumer identity details are generally optional on B2C invoices, except in specific cases (transactions ≥ USD 25,000, when the customer needs the invoice for tax deductions, or when the customer requests the invoice). In those cases, the customer’s name and identification number (Tax ID, DUI number, passport or other ID) must be included on the e-invoice, and failing to obtain those details when required can trigger a penalty (30% of the transaction value, minimum two monthly wages) under the newly amended Tax Code. For typical retail transactions, however, detailed personal info is not mandatory on the electronic invoice. This approach balances compliance needs with privacy and convenience for small transactions.

-
Domestic B2G Transactions (Business-to-Government): Sales to government entities (B2G) fall under the e-invoicing mandate as well. Public-sector institutions that are VAT-registered must be issued electronic tax documents by their suppliers. In practice, these are usually treated similarly to B2B invoices (a government entity will have a Tax ID (NIT) and be recorded as the customer on a CCFE or invoice DTE as appropriate). Moreover, certain government entities that serve as VAT withholding agents (e.g. some ministries, municipalities, and public institutions) have been specifically included in the e-invoicing system and must use DTEs for their transactions. B2G invoices are generated and cleared through the same platform and processes as other invoices. There are no separate document types exclusively for B2G; rather, the existing DTE categories (e.g. tax credit invoices, receipts, etc.) are used to cover transactions with government buyers. This ensures that procurement by government bodies is captured under the electronic system, improving transparency and VAT control (a key goal of the mandate). [taxathand.com] [fonoa.com], [sovos.com]
-
Cross-Border Transactions (Imports & Exports): The e-invoicing regime also encompasses international transactions, primarily through a special export invoice type. When Salvadoran businesses export goods or services, they must issue a “Factura de Exportación Electrónica (FEXE)”, which is a DTE designated for export sales and used to document cross-border B2B/B2G sales leaving El Salvador. The electronic export invoice carries a VAT rate of 0% (zero-rated for exports) but otherwise follows the standard DTE clearance process, with two newly added fields to identify third-party principals in case the export is carried out on behalf of another entity. (These new third-party identification fields in export invoices, such as the third party’s ID number and name, become mandatory from February 17, 2026 to handle scenarios where one taxpayer exports goods on behalf of a different company). [ivacalculator.com] [edicomgroup.com]For imports, foreign suppliers are not subject to El Salvador’s DTE issuance requirement if they are not tax-registered in El Salvador. Imported goods are generally accompanied by customs documentation and the importer pays any applicable VAT via the import process rather than through a local invoice. Thus, inbound cross-border B2B transactions (purchases from foreign suppliers) are outside the scope of the DTE clearance system unless the foreign supplier has a local VAT registration. (If a non-established supplier is registered for Salvadoran VAT, e.g. via a tax representative, then that supplier would be treated akin to a local taxpayer and would need to issue DTE invoices for its El Salvador transactions.) Beyond the export invoice, no separate “e-reporting” mechanism for cross-border transactions has been mandated. In other words, there is no requirement for Salvadoran companies to send additional electronic reports for cross-border transactions outside of the standard DTE electronic invoice process. Taxable exports are simply reported by issuing a FEXE export e-invoice, and imports continue to be handled via customs and VAT returns rather than through the DTE portal. (El Salvador is not part of the EU, so EU-specific concepts like “intra-Community acquisitions/supplies” do not apply in the domestic mandate.) [consortiumlegal.com]
-
Self-Billing: Self-billing – where the buyer, instead of the seller, issues the invoice – is not explicitly detailed in the current Salvadoran e-invoicing regulations available publicly. The framework generally assumes the supplier is the DTE issuer. If self-billing were conducted (for example, in certain industries or by special agreement), the expectation is that an electronic tax document would still need to be generated and submitted through the DTE system on behalf of the transaction, with the roles of issuer and recipient appropriately reflected. However, to date no specific “self-billing” DTE type or procedure has been published. Any self-billed invoice would likely need to meet all the same requirements (digital signature, JSON format, clearance via the DGII platform) and might require prior authorization or arrangement with the tax authority – but no formal public guidance has been found on this scenario as of the latest updates. Companies engaging in self-billing should seek confirmation from the DGII and ensure the electronic documents are compliant with DTE standards (most likely by treating the buyer as the issuer of a standard DTE, with the seller recorded as the recipient). [ivacalculator.com]
-
Triangulation & Chain Transactions: Similarly, triangular or chain transactions (where multiple parties are involved in a supply chain or intermediaries issue invoices for goods delivered from a third party) are not specially carved out in the published DTE regulations. In practice, each leg of a chain that constitutes a taxable transaction in El Salvador must be documented with a compliant DTE issued by the responsible supplier. There is currently no unique DTE just for triangulation; businesses should use the standard invoice types (e.g. FE, CCFE, etc.) to cover each transaction and ensure that the flow of goods and invoices is properly documented for all legs of the chain. Notably, when a transaction is carried out “on behalf of a third party” (for example, an agent or intermediary facilitating a sale), the DTE rules now require disclosure of the third party’s identification on the invoice (this requirement was introduced in late 2025 for export invoices). This addition helps capture chain transactions by linking the third-party principal to the DTE. Other special VAT scenarios (such as consignment sales or agency sales) would follow the general DTE process as well, using the appropriate type of document (e.g. a Settlement Receipt or Settlement Accounting Document DTE may be used for certain commissionaire or consignment sale situations). Businesses involved in complex multi-party transactions should consult DGII’s guidance to determine the correct DTE type for each scenario, but in all cases the mandate’s principle holds: every VAT-taxable transfer of goods or services must be accompanied by an electronic tax document submitted to the authorities.

-
Special VAT Regimes: Special VAT regimes (e.g. simplified regimes, small taxpayer regimes, or sector-specific VAT schemes) have not been exempted from the e-invoicing requirements. All VAT-registered persons, regardless of regime, are expected to issue DTEs for their taxable operations. For instance, even small retailers or taxpayers under any presumptive/margin schemes must issue electronic invoices; there is no separate invoice format for margin scheme sales or travel agency commissions – those can be accommodated within the standard DTE by indicating the appropriate VAT treatment (such as zero-rated or exempt) in the invoice details. The electronic format includes fields to denote tax rates, exemptions, and special conditions on each invoice line, so special transactions like VAT-exempt sales or sales under special regimes are handled by populating the relevant fields (such as a code for “exempt” or “not subject” supply) in the JSON/XML structure. In summary, the DTE mandate is economy-wide – covering B2B, B2C, B2G, exports – with no general exclusions for specific sectors or foreign companies (if they are registered for Salvadoran VAT). All such transactions must be documented by an appropriate electronic tax document and transmitted to the tax authority’s system.

2. Taxable Persons in Scope
The e-invoicing mandate applies broadly to all “taxable persons” registered for VAT in El Salvador, whether resident or non-resident. Key inclusions and considerations:
The e-invoicing mandate applies broadly to all “taxable persons” registered for VAT in El Salvador, whether resident or non-resident. Key inclusions and considerations:
-
Established Domestic Entities: All businesses established in El Salvador and registered for IVA (VAT) are required to comply with electronic invoicing obligations. This includes corporations, partnerships, and individual entrepreneurs that are VAT taxpayers. In practice, “all natural and legal persons registered as VAT contributors must issue digital tax documents in real time to the Ministry of Finance”, according to guidance published in August 2025. There is no differentiation – once a business has an IVA tax identification number (NIT), it falls under the mandate (subject to the phased schedule discussed in Section 3). Even small and medium enterprises (SMEs) are included, with the tax authority providing a specialized onboarding process and free tools to assist smaller firms (see Section 12). [elsalvador.com] [elsalvador.com], [elsalvador.com]
-
Non-Established Entities with VAT Registration: Foreign or non-resident entities that are registered for Salvadoran VAT (e.g. through a local branch, subsidiary, or appointed tax representative) are equally subject to the e-invoicing requirements. The Tax Code reforms and subsequent regulations do not exempt non-resident taxpayers who have VAT obligations in El Salvador. In fact, the 2024 reform explicitly addresses information requirements for foreign customers and entities: for example, foreign individuals or companies (whether domiciled in El Salvador or not) must provide identification details (name, foreign tax ID or passport number, etc.) for inclusion on the invoice if the transaction exceeds $25,000 or if they need the invoice for tax purposes. This indicates that foreign businesses engaged in taxable transactions in El Salvador are contemplated by the system. If a non-established company makes sales in El Salvador and is required to be VAT-registered, it must issue DTE invoices for those sales just like a local company would. [consortiumlegal.com], [consortiumlegal.com]
-
Foreign Entities without a Fixed Establishment: Generally, foreign companies without a local establishment (and not registered for VAT) are not directly subject to El Salvador’s e-invoicing mandate, since they are outside the local tax jurisdiction. For example, a foreign company selling goods to a Salvadoran business would not issue a Salvadoran DTE unless it had registered as a taxpayer in El Salvador. Instead, the transaction might be treated as an import on the Salvadoran side. In such cases, the Salvadoran importer would account for VAT via customs/import declarations rather than an electronic invoice, and no DTE is expected from the unregistered foreign seller. In summary, the e-invoicing rules apply at the level of taxable persons under Salvadoran law – if an entity (domestic or foreign) is registered and required to charge Salvadoran VAT, it is in scope; if it has no such registration or obligation, it generally falls outside the mandate.
-
Exemptions and Special Cases: No blanket exemptions from the e-invoicing mandate have been granted for particular industries or sectors. The transition is intended to eventually cover all sectors and all sizes of business. However, the adoption is being implemented in phases (see Section 3), and taxpayers who have not yet been officially notified of their start date are not obliged to use e-invoicing until their turn comes. During this interim, they may continue using traditional paper invoices or fiscal tills. Certain special entities (like diplomatic organizations or non-profits) might not be VAT-registered and thus are not issuing tax invoices at all; they remain outside the scope unless they engage in taxable sales. Additionally, as of late 2024, the law introduced clarifications on which customer information must be collected for invoicing (as discussed above) and imposed penalties for over-collecting data in cases where it’s not required. These rules apply to both paper and electronic invoices; thus, even businesses still using paper (pre-DTE) must heed the new requirements when issuing invoices. [consortiumlegal.com]
-
Voluntary Participation: The government has allowed and even encouraged voluntary early adoption of e-invoicing for businesses not yet mandated. The DGII set up a registration process enabling any taxpayer to opt in to the DTE system before their required date. Businesses could apply to be authorized as DTE issuers and begin issuing electronic tax documents in advance of their official deadline. This voluntary phase (starting in late 2022 and 2023) aimed to let willing companies gain experience with the system and encourage smoother overall adoption. As of early 2023, hundreds of companies had already enrolled voluntarily in preparation for mandates. There are also indications that the tax authority conducted a controlled pilot program in 2019 with around 50 large taxpayers to test the system prior to nationwide rollout. [edicomgroup.com] [vatcalc.com]
-
Sector-Specific Rules: No unique sector-based exclusions are defined in the e-invoicing law. All industries – including finance, hospitality, retail, manufacturing, etc. – must implement DTE when required. Government publications have not singled out any specific industry for exemption. However, the tax authority did create special accommodations for small businesses (see Section 12) by providing a free invoicing portal and by phasing their onboarding later in the schedule. Additionally, certain unique transaction types are covered by specialized DTE documents: e.g. agricultural producers receiving payments under special regimes use a “Comprobante de Liquidación Electrónico (CLE)”, and non-taxable entities (like small informal suppliers or exempt organizations) can be issued a “Factura Sujeto Excluido (FSEE)” for purchases they make. These ensure that even transactions involving parties under special regimes are captured in the electronic system when a VAT-registered taxpayer is involved. In summary, the e-invoicing obligation is defined primarily by a taxpayer’s status under the VAT law (and the phase-in calendar), rather than by sector. All registered VAT taxpayers – whether large multinational companies or local SMEs – will eventually fall in scope of mandatory DTE compliance. [elsalvador.com], [taxathand.com] [ivacalculator.com]
3. Implementation Timeline
El Salvador’s e-invoicing rollout has been phased in over several years, moving from legal groundwork through pilots and voluntary adoption into staggered mandatory adoption for different taxpayer segments. Key milestones in the implementation timeline include:

-
2019 (Pilot Phase): The Ministry of Finance (MH) and General Directorate of Internal Taxes (DGII) initiated a controlled pilot program in 2019 with about 50 large taxpayers to test the electronic invoicing system (in part delayed by the pandemic). This pilot allowed authorities to refine the DTE platform and take cues from established e-invoicing models in countries like Chile, Colombia, Argentina, Peru, and Mexico. [vatcalc.com] [fonoa.com]
-
August 30, 2022 – Legal Adoption: El Salvador’s Legislative Assembly approved Legislative Decree No. 487/2022 on August 30, 2022, which amended 14 articles of the Tax Code and introduced new provisions to formally enable Electronic Tax Documents (DTEs) as legal invoices. This decree (published in the Official Gazette on September 20, 2022) empowered the Tax Administration (Ministry of Finance/DGII) to set the rules, formats, and timelines for implementing e-invoicing, to define required fields and technical standards, and to mandate when taxpayers must switch to electronic invoicing. The decree came into force in October 2022, serving as the legal foundation of the e-invoicing system. [edicomgroup.com], [fonoa.com] [europe.tho…euters.com]
-
Late 2022 – Early 2023 – Regulations and Guidelines: Following the law, the DGII issued detailed “Compliance Regulations for Electronic Tax Documents” on January 13, 2023. These regulations (Normativa de Cumplimiento) and accompanying technical documentation specified the data schema (local JSON format), processes for issuance/transmission, security requirements, and procedures for contingency and cancellation of e-invoices. On October 27, 2022, even before the regulations, the Tax Administration had already published a series of guidelines and manuals to help taxpayers prepare for e-invoicing, including: an orientation guide for becoming a DTE issuer, a technical guide to JSON schemas for each DTE type, user manuals for the DTE web portal, instructions for obtaining digital certificates, etc.. These resources were made available on a dedicated informational portal (info.dtes.mh.gob.sv and factura.gob.sv) for public consultation. [taxathand.com] [sovos.com], [sovos.com] [taxnews.ey.com], [taxnews.ey.com] [taxnews.ey.com]
-
2023 – Voluntary Adoption and Initial Mandatory Phase: Throughout 2023, the DGII began onboarding taxpayers. The first mandatory wave targeted large taxpayers. Although a single public “big bang” date was not announced, the tax authority notified large companies individually of their go-live dates, beginning around mid-2023. For example, some sources report that the phased rollout started in July 2023 for certain groups. During this period, taxpayers not yet mandated could opt in voluntarily to start using DTE early, after completing the required registration and testing steps. The Ministry of Finance also launched an online lookup tool (“Find out when you need to become an issuer” portal) where businesses could input their Tax ID (NIT) to see their assigned mandatory start date for issuing DTEs. By March 2023, the government confirmed that no taxpayer group was universally mandated yet, but the “mandatory DTE implementation plan” had kicked off and emails were being sent to taxpayers with their specific compliance deadlines. [edicomgroup.com]
-
2024 – Expansion to Medium and Small Taxpayers: The e-invoice mandate expanded to broader segments of the economy in late 2023 and into 2024. Medium-sized companies began to be incorporated as the year progressed. By April 2024, official reports indicated that 93% of large taxpayers, 33% of medium taxpayers, and 20% of small taxpayers were already issuing DTEs as part of the phased rollout. The Ministry of Finance publicly projected May 2025 as the final deadline by which all taxpayers would be on electronic invoicing. In the interim, if businesses had existing stocks of pre-printed paper invoices (known as “VAT control documents”), they were allowed to continue using them until their assigned switch-over date. Once a taxpayer’s e-invoicing start date arrives, they must report any remaining unused paper invoices to the tax authority for cancellation and destruction within 15 business days. Notably, a new requirement for B2C transactions came into effect on January 1, 2025: all taxpayers who are obliged to e-invoice must issue electronic consumer invoices (“e-tickets”) for retail sales instead of traditional paper tickets. This was part of the push to ensure that even B2C sales by large retailers are captured in real time.

2025 – Full Mandate and Final Adjustments: By 2025, El Salvador’s e-invoicing mandate was well underway, with thousands of companies of all sizes incorporated. In fact, by late 2024, over 14,000 taxpayers were registered DTE issuers (about 13% of all VAT-registered taxpayers, accounting for ~89% of total sales volume in the country). The ultimate goal was to reach 100% of VAT taxpayers. The Ministry of Finance’s schedule targeted May 2025 as the point by which all remaining taxpayers would be brought into the system. The rollout did not rely on taxpayer size alone; while large taxpayers were first, smaller businesses (categorized as “Otros”) were gradually notified of their deadlines. Taxpayers typically receive a notice 3–4 months in advance of their mandatory go-live date to allow time for preparation and testing. [ivacalculator.com], [ivacalculator.com] [elsalvador.com], [elsalvador.com]By February 2025, virtually all large companies and most medium-sized companies had converted to DTE. Small businesses and certain specific groups (including newly-registered businesses) were the last wave, with many of those scheduled in early to mid-2025. The government’s phased approach allowed it to provide support and manage the transition effectively. No general “grace period” after one’s go-live date is mentioned in regulations – once a taxpayer’s assigned date passes, e-invoicing is mandatory for them. However, the entire program’s timeline was somewhat flexible: if necessary, authorities could adjust schedules. (Some later industry commentary suggests that a few stragglers and special cases might continue being integrated into 2026, but officially the aim has been full coverage by 2025.) [ivacalculator.com]
-
Legislative Adjustments: During the rollout, El Salvador fine-tuned its framework via additional legislation. For example, Legislative Decree No. 960 of Feb 29, 2024 introduced new mandatory fields in the “recipient” section of electronic invoices for high-value transactions (≥ $25,000). And in September 2024, Decree No. 94/2024 clarified which customer information is optional vs mandatory on invoices, as described above (Section 1), and established penalties for over-requesting data. Additionally, norms effective January 2025 required businesses to switch from paper consumer receipts to electronic tickets for B2C sales. The DGII also periodically updates the technical specifications: e.g., in March 2023, the JSON schema definitions for various DTE types were modified (affecting fields like invoice numbering, tax details, payment info, etc.) to improve the system. These updates require taxpayers (especially early adopters) to adjust their systems accordingly. Looking ahead, further refinements (such as changes to numbering formats and code catalogs scheduled for October 2026) have been announced to continuously enhance the e-invoicing framework.

4. Technical & Functional Requirements
The DTE system in El Salvador is governed by strict technical specifications and functional requirements set by the DGII. These ensure that all electronic invoices and reports are uniform, complete, and verifiable. Key technical and functional aspects include:
The DTE system in El Salvador is governed by strict technical specifications and functional requirements set by the DGII. These ensure that all electronic invoices and reports are uniform, complete, and verifiable. Key technical and functional aspects include:
-
Standard Format (JSON Schema): Electronic invoices (DTEs) in El Salvador must be generated in a structured, machine-readable format, specifically a JSON (JavaScript Object Notation) format defined by the tax authority. The DGII has published official JSON schemas for each type of DTE and related event (such as invoice issuance, cancellations/voids, etc.), which outline the required structure and fields. This local JSON format is a custom schema (not based on UBL or PEPPOL BIS, but tailored to Salvadoran requirements). Taxpayers must ensure their e-invoicing software can produce JSON files exactly as specified by DGII’s technical documentation. Notably, some early adopters had to update their systems in 2023 when the Ministry of Finance adjusted the JSON schemas for eight types of DTEs – including fields for invoice numbering, tax details, payment information, and contingency data – as part of ongoing improvements. [taxathand.com] [europe.tho…euters.com] [europe.tho…euters.com], [europe.tho…euters.com]
-
Mandatory E-Invoice Data Fields: Each electronic invoice must include all information required by the Tax Code and DTE compliance regulations. The regulations on DTE content largely mirror the information previously required on paper invoices, with some enhancements. Key mandatory data elements include:
- Unique Invoice Identifiers: Every DTE has a unique consecutive control number (with a structured format like 8-digit series and sequential number) and a system-generated “Código de Generación” (e.g., a UUID) to uniquely identify the document. [ivacalculator.com]
- Dates and Timings: The invoice issue date and time of generation must be included, as well as the date/time of clearance (receipt stamp) from the tax authority. This ensures real-time or near-real-time traceability.
- Supplier (Issuer) Details: The DTE must contain the issuer’s Tax Identification Number (NIT), National Registration Code (NRC, which is a business registration number for VAT-payers), legal name, address, and other registration details. (Some fields like the NRC or economic activity code are optional in cases where they don’t apply – for instance, an individual consumer wouldn’t have an NRC – and the DTE compliance rules explicitly mark such fields as optional to accommodate different scenarios.) [consortiumlegal.com], [consortiumlegal.com]
- Customer (Recipient) Details: The recipient’s name and identification (Tax ID or other official ID number) must be included when required by regulations – e.g., for large transactions (≥ $25k), for transactions where the buyer requests an invoice (even if a consumer), or to support tax deductions. If the customer is a legal entity, the business name and Tax ID should always be included regardless of amount. For everyday consumer sales below the threshold and not for expense claims, customer details can be minimal (the system allows “consumer” invoices without full ID in such cases). [europe.tho…euters.com], [europe.tho…euters.com] [europe.tho…euters.com] [europe.tho…euters.com], [consortiumlegal.com]
- Line-Item Details: A description of each item or service supplied, quantity, unit price, and any discounts or credits. The system requires breaking down the tax calculation for each line – indicating the applicable VAT rate (standard 13% or exempt/0%), the tax amount, and classifying each line as taxable, exempt, or zero-rated as appropriate. The digital format uses specific codes for tax categories (e.g., codes to denote standard-rated vs. exempt sales) to facilitate automated tax determination. [ivacalculator.com]
- Totals and VAT Breakdown: The invoice must show the subtotal, VAT amount, and total amount. The JSON schema enforces that line-item sums must match the invoice totals and the 13% VAT calculation precisely, or the invoice will be rejected by the system for inconsistency. [azteq.software]
- Invoice Type and References: The DTE indicates its type (invoice, credit note, etc.) via a code. Certain DTE types (Credit Notes, Debit Notes) must reference the original invoice they are modifying (by including the original invoice’s key details such as control number and date). [edicomgroup.com], [edicomgroup.com]
- Other Mandatory Fields: Additional fields include invoice currency and exchange rate (if not in USD), payment terms or payment method, and if applicable, information about any contingency events (used when the standard process is disrupted). For example, if an invoice is issued in “contingency mode” due to system downtime, the DTE must indicate the contingency type and reason. (However, the display of some data on the paper/PDF copy can be simplified: for instance, currency code and contingency reason are not required to be printed on the human-readable representation, even though they are in the JSON file.) [europe.tho…euters.com], [europe.tho…euters.com]
-
E-Reporting Data Model: The e-reporting component in El Salvador is intrinsically tied to the e-invoice data. There isn’t a separate standalone “e-report” format (as seen in some countries); instead, the structured data from DTE invoices serves as the source of reporting. The tax authority’s system effectively compiles the reported sales and purchase data from all the clearance submissions. For example, the VAT return form (Formulario F-07) now automatically pulls data from the DTE system into its annexes: taxable and exempt sales are populated from the DTE “Annex 1 and 2” data, purchases and VAT credit claims from DTE Annex 3 and 5, and withholding information from electronic withholding receipts (CRE) and related reports. This means much of the VAT reporting is based directly on the e-invoice data model and the underlying JSON fields. The DTE compliance framework defines what must be reported for each transaction (who, when, how much VAT, etc.), and the system uses that data for both audit and return-preparation purposes. [ivacalculator.com]
-
Digital Signatures & Security: Each Electronic Tax Document must be digitally signed using an electronic signature certificate issued by the DGII (the tax authority) or its authorized providers. Obtaining this certificate is one of the prerequisites for any company to become a DTE issuer. The digital signature is embedded in the DTE (in the JSON file) and ensures the integrity and authenticity of the invoice data. It guarantees that the document has not been tampered with and confirms the identity of the issuer. The Ministry of Finance has established a process for taxpayers to secure these certificates (including a testing certificate for pilot use and a production certificate once authorized). Without a valid signature, the DTE will not be accepted by the system. Additionally, the DTE platform uses security and validation rules to ensure data integrity – for example, the system will reject any invoice where calculated totals or required fields are inconsistent or missing, prompting the issuer to correct and re-send the data (see Section 5 on corrections). [latinalliance.co], [latinalliance.co] [azteq.software]
-
Real-Time or Near Real-Time Processing: El Salvador’s DTE system is designed for immediate or very prompt processing of invoices. The law requires transmission of the DTE to the tax authority essentially at the time of issuance. In practice, this happens via automated APIs for integrated systems or instantly through the web portal for small issuers. The tax authority’s platform performs validation checks on each submitted invoice in real time. If the invoice passes validation, a digital “receipt stamp” is returned almost instantaneously to the issuer, allowing the transaction to be completed (i.e. the goods or services can be delivered along with a valid tax-compliant invoice). This effectively means “T+0” reporting – invoices are reported and cleared immediately upon generation. There is no general allowance for delaying submission (such as next-day “T+1” reporting), except in officially declared contingency situations. In normal operation, the clearance must be obtained before sending the invoice to the buyer. For certain documents – e.g. invoices to final consumers (B2C) – the requirement of real-time transmission became explicit from 2025, when paper consumer receipts were phased out. [europe.tho…euters.com]Additionally, summary reporting is not a feature of the DTE system for in-scope transactions, since every transaction is individually reported. However, businesses still prepare monthly VAT summaries (returns) from the data – which, as noted above, can now be largely automatically compiled from the cleared DTEs via the tax authority’s online system.

Validation Rules and Rejection Handling: The DTE platform applies automated validation rules upon invoice submission. Common reasons an e-invoice might be rejected by the system include: invalid or unregistered Tax IDs (e.g., if the buyer’s NIT is incorrect or not found), arithmetic discrepancies in tax calculations (totals not matching line items), missing mandatory fields, or issues with the digital signature certificate. When a DTE is rejected during submission, the issuer is notified (for instance, the system returns a rejection code or error message). The invoice is not granted a receipt stamp and is not considered issued, so the seller must correct the errors and re-submit a corrected DTE. The system supports resubmission of a corrected invoice using the same sequential number (no new invoice number needed) after fixing issues, as long as this is done promptly. These real-time validations greatly reduce errors in invoices and thus help catch tax calculation mistakes or missing data before the invoice is finalized, improving overall data accuracy and compliance.

5. Correction of Errors in E-Invoices and E-Reporting
The Salvadoran e-invoicing regulations provide mechanisms to correct errors on electronic tax documents. The processes differ slightly depending on the type of document and the timing of the correction. Key procedures for handling corrections include:
The Salvadoran e-invoicing regulations provide mechanisms to correct errors on electronic tax documents. The processes differ slightly depending on the type of document and the timing of the correction. Key procedures for handling corrections include:
-
Voiding or Annulling E-Invoices (Invalidación): If an error is discovered in a fully issued electronic invoice (DTE), one option is to void (invalidate) the invoice through the tax authority’s system. According to the compliance regulations, a DTE can be “invalidated” after issuance if errors are found that do not affect the underlying transaction – essentially canceling the e-invoice without altering the fact that the sale occurred. However, there are strict deadlines for performing such voids: [sovos.com]
- For a standard electronic invoice (FE) or an electronic export invoice (FEXE), the void (anulacíon) must be carried out within 3 months from the date of the original invoice’s receipt stamp. If an invoice to a customer needs to be canceled or significantly corrected (resulting in a reduction of tax liability), the seller has up to 3 months to submit a voiding “event” through the DTE system referencing that invoice. After the 3-month window, the system will not allow a void event for that document. In that case, any necessary adjustments would have to be made using credit or debit notes instead (see below).
- For a Comprobante de Crédito Fiscal (CCF) – the B2B invoice/receipt – the allowed voiding period is much shorter. A CCF (electronic tax credit invoice) can only be voided within 24 hours of its clearance (i.e., within one day from when the receipt stamp was issued). If a mistake in a B2B invoice is noticed immediately (such as within the same day), the issuer may void the CCF via the platform. After 24 hours, the CCF can no longer be voided; instead, a credit note or debit note DTE must be issued to correct any errors (for instance, to adjust amounts).
- It’s important to note that voiding an invoice in the DTE system doesn’t mean erasing it – rather, it registers an “invalidated” status for that document in the tax authority’s records. The original invoice and the void event are both kept on file (preserving an audit trail). Voiding should only be used for true cancellations or errors; it is not a way to avoid reporting a sale. For example, a void is typically appropriate when an invoice was issued in error or the entire sale is canceled.
-
Credit and Debit Notes (Correcciones via Notas): For errors discovered after the allowed voiding period (or for errors that affect the transaction’s tax base/amount), issuing a Credit Note (Nota de Crédito Electrónica – NCE) or Debit Note (Nota de Débito Electrónica – NDE) is the prescribed method of correction. Credit and debit notes are themselves DTE documents that must reference the original invoice’s details. Key rules include: [edicomgroup.com], [ivacalculator.com]
- A Credit Note can be used to correct an overcharged amount or to cancel all or part of an invoice’s value (essentially reducing the taxable amount or undoing a transaction). For instance, if an invoiced amount was too high or goods were returned, an NCE is issued to amend the original DTE. The credit note DTE will contain a reference to the original invoice’s unique code/number and the corrected values (e.g. negative line items or adjustments). Timing: Credit notes that adjust an original invoice must be issued within 3 months from the date of the original invoice’s clearance. After 3 months, no further adjustments can be made via credit note either, so taxpayers must ensure errors are addressed within this window. (Notably, the 3-month limit applies as well to credit notes adjusting withholding receipts, as per Tax Code Art. 119-E – e.g., a credit note can adjust an electronic withholding certificate (CRE) within 3 months of the original CRE.) [sovos.com]
- A Debit Note is used to increase the amount of a previously issued invoice (for example, if an underbilling or omitted charge is discovered). Like credit notes, an NDE must reference the original invoice’s details and be issued within the allowed period (generally within 3 months of the original invoice’s stamp date) to be valid. Both credit and debit notes must themselves go through the same clearance process (JSON format, digital signature, submission to DGII) and will receive their own receipt stamps. They effectively become part of the official record, adjusting the amounts of the original transaction.
-
Error Notification and Reporting Corrections: In the context of e-reporting, since each DTE is cleared by the tax authority as it is issued, there isn’t a separate periodic error correction filing. Instead, corrections are handled at the document level via the voids and notes described above. If an error is discovered in data already reported through a DTE (for example, a mis-stated amount or the wrong tax classification), the company should issue the appropriate corrective DTE (void or credit/debit note) to amend the record with the tax authority. The DGII’s platform links these events with the original transaction, ensuring the tax data is updated. Taxpayers must also reflect these corrections in their internal accounts and in the VAT return for the relevant period. If a reporting error is identified after an official filing (e.g., after a monthly VAT return has been auto-populated by DTE data), the taxpayer may need to file an amended return in line with general tax procedures. The DTE system itself does not have a separate “amendment report” – rather, the correction of the source invoice data (via DTE void or note) will flow into the tax authority’s records and thus into any pre-filled tax return or VAT ledger (see Section 11).
-
Specific Forms or Notifications: Aside from issuing the corrective DTEs, taxpayers generally do not need to submit separate paper forms to correct an e-invoice. The electronic credit note or voiding event is the official mechanism to rectify the error. However, if an e-invoice was incorrectly reported (for example, not reported at all due to a system issue), and the window for electronic correction has passed, the taxpayer should likely inform the tax authority and correct the error through the appropriate channels (which might involve an exceptional administrative process or adjustments in the next tax return). In any case, adhering to the 24-hour and 3-month deadlines for voids and notes is critical to avoid having to seek special approval for late corrections. The DTE compliance guides emphasize that taxpayers should carefully review data to minimize errors and use the online “inconsistency dashboard” before each monthly filing to catch any issues (the DTE portal provides tools to compare the accumulated invoice data with return data).

6. Transmission & Workflow
El Salvador’s e-invoicing system uses a centralized clearance platform operated by the tax authority (Ministry of Finance’s DGII) to receive, validate, and approve all electronic tax documents before they are considered valid. The workflow and transmission process can be summarized as follows:
El Salvador’s e-invoicing system uses a centralized clearance platform operated by the tax authority (Ministry of Finance’s DGII) to receive, validate, and approve all electronic tax documents before they are considered valid. The workflow and transmission process can be summarized as follows:
-
Transmission Channels: There are two primary ways to transmit DTEs to the tax authority: (1) via an integrated “DTE transmission system” (API connection) linked to the taxpayer’s own billing software, or (2) via the government’s web-based DTE invoicing portal for smaller taxpayers. Larger companies typically use the first method: their internal ERP or billing system is adapted to produce the DTE JSON and connect to the DGII’s web service. Smaller businesses (classified as “Otros”) have the option to use the free online DTE system provided by DGII, which allows manual entry and submission of invoices through a web interface. In both cases, the data ultimately goes to the same central platform. Some taxpayers may also choose to use third-party authorized service providers or software solutions that connect to the DGII’s API on their behalf (these act as intermediaries but must conform to the same standards). Notably, the DTE law allows for both direct reporting and using certified providers, similar to the models in other LatAm countries. In either case, PEPPOL is not used in El Salvador’s system – the country relies on its own national platform and standards, rather than the PEPPOL network which is more common in European e-invoicing.

-
Workflow Steps: Once a business has prepared an invoice in its system, the typical workflow is: (a) the DTE is generated in the required format with all data fields; (b) the DTE is digitally signed using the taxpayer’s electronic certificate; (c) the signed file is transmitted via API or uploaded via the portal to the DGII in a machine-readable form; (d) the DGII’s system performs automated checks and, if everything is in order, issues a unique Authorization Receipt (receipt stamp or “Sello de Recepción”) and returns this to the issuer; (e) the supplier then delivers the approved invoice to the buyer (commonly by email with a human-readable PDF and the XML/JSON file attached, or via the customer’s web service). The buyer can verify the invoice’s validity online using the unique code or QR provided. If the DGII instead finds errors, it sends back a rejection notice (with error codes), and the issuer must correct the DTE and re-submit it (see Section 4 and 5 above on validation and corrections). This clearance process typically happens in seconds or minutes, allowing for real-time or near-real-time invoice issuance in day-to-day operations. [azteq.software], [azteq.software]
-
Deadlines for Transmission: The general rule under the clearance model is immediate (real-time) transmission – an electronic invoice should be sent to the tax authority essentially at the moment of generation/issuance. The tax code authorizes the DGII to establish specific deadlines (“form, terms and conditions”) for transmission of DTEs. In practice, the DGII requires that DTEs be transmitted and approved before they are considered valid invoices. This means a supplier cannot lawfully delay sending the invoice data; you must get the clearance first and then deliver the invoice to your customer. There’s no standard provision of “T+1” (next-day) reporting for normal operations. However, the system does account for contingencies: if the online system or internet is down, a taxpayer might be allowed to issue invoices in contingency mode and transmit them as soon as the issue is resolved. The “Compliance Regulation” includes provisions on how to handle such contingencies (e.g., marking the invoice as a contingency document and sending it when connectivity is restored), though the goal is to minimize delays in reporting. Apart from real-time invoice clearance, some periodic summaries of certain transactions were historically required (for example, reporting of traditional paper invoices or credit notes in monthly VAT ledgers). With full e-invoicing, those separate reports are being supplanted by the DTE system. For instance, from January 2025, monthly B2C sales must be captured by individual e-tickets rather than summarized later. As such, the DTE platform is moving compliance from after-the-fact reporting to ongoing, transaction-by-transaction reporting. [europe.tho…euters.com] [sovos.com]
-
Workflow for E-Reports: As noted, El Salvador’s approach merges e-invoicing and e-reporting. The “reporting” element is inherent in the clearance process. There is no additional file that businesses must send at month-end to report their sales or purchases – the tax authority’s system has already received each invoice and even populates the taxpayer’s VAT records (see Section 11). One exception might be certain transactions that are out of scope of DTE (for example, if a taxpayer was allowed to temporarily issue a paper invoice during a system outage or prior to their mandated start date). In such cases, the taxpayer still has to report those transactions via existing means (e.g., include them in the routine VAT return, or possibly use the portal to enter them once online). But once a taxpayer is fully live on DTE, the electronic workflow itself fulfills the “reporting” duty. The system is designed to create an automatic link between transaction issuance and government reporting – a key benefit being the near-elimination of separate manual VAT reporting for transactions that have DTE coverage. [ivacalculator.com] [elsalvador.com]
7. Self-Billing
Self-billing – where the buyer prepares the invoice in lieu of the supplier – is not common in El Salvador and is not explicitly detailed in the e-invoicing regulations. The standard model assumes that the invoice is issued by the supplier (the seller), who must generate a DTE and send it to the tax authority. The available official documentation and regulations reviewed do not mention a distinct procedure for self-billed invoices, nor is there a dedicated DTE document type for self-billing. Therefore, any self-billing arrangements would need to operate within the existing framework: for instance, the parties would likely have to agree that the buyer acts as a facilitator but the invoice still is issued as a DTE in the name of the seller (with the appropriate digital signature and transmission to DGII). In effect, the buyer preparing the invoice on the supplier’s behalf would need to ensure the invoice gets properly registered in the supplier’s DTE system and cleared by the tax authority. Without official guidelines on self-billing, participants in such arrangements should proceed cautiously and likely seek advance approval or confirmation from the DGII. Key considerations include: [ivacalculator.com]

Therefore, any self-billing arrangements would need to operate within the existing framework: for instance, the parties would likely have to agree that the buyer acts as a facilitator but the invoice still is issued as a DTE in the name of the seller (with the appropriate digital signature and transmission to DGII). In effect, the buyer preparing the invoice on the supplier’s behalf would need to ensure the invoice gets properly registered in the supplier’s DTE system and cleared by the tax authority. Without official guidelines on self-billing, participants in such arrangements should proceed cautiously and likely seek advance approval or confirmation from the DGII. Key considerations include: [ivacalculator.com]
- Use of the DTE Platform: The invoice – even if prepared by the buyer – must be submitted through the official e-invoicing platform for clearance, under the supplier’s tax identification and signature. The buyer would probably need access to the supplier’s DTE system (or an interface) to issue the invoice in real time.
- Buyer’s Validation/Approval: There is no indication of a separate buyer validation step in the current Salvadoran system. The buyer’s role is primarily to receive the cleared invoice and, if the buyer is tax-registered, ensure it is recorded for their VAT credit. Any approval workflow (if the buyer must approve a self-billed invoice before clearance) would have to be managed contractually between the parties, since the government’s system doesn’t currently provide a built-in buyer approval portal.
- Mandatory Content: A self-billed invoice would contain the same mandatory fields as any other DTE, but with the buyer effectively filling in the details on the supplier’s behalf. The invoice would still list the supplier as the “issuer” (with their NIT, etc.) and the buyer as the “recipient,” preserving the tax law’s requirement that the supplier issues tax invoices. The digital signature would need to be that of the supplier (or an authorized third-party provider acting for them), as only certificates issued to registered taxpayers can sign DTEs. [ivacalculator.com]
- Notification or Authorization: While not explicitly required by the e-invoice legislation, general VAT practice might require that a self-billing arrangement be documented (e.g., the supplier’s consent for the buyer to issue invoices on their behalf). It would be prudent for businesses to notify or seek permission from the DGII if they plan to implement self-billing, to ensure it aligns with tax rules.
In summary, self-billing is neither expressly prohibited nor specifically provided for under El Salvador’s e-invoicing rules as of the latest available information. The safest approach for any self-billing scenario is to treat the invoice as a normal DTE issued in the supplier’s name (with all required data and clearance) and maintain clear agreements between the parties. Businesses should keep an eye on future DGII guidance in case self-billing rules are formalized.
8. Triangulation & Special Scenarios
El Salvador’s e-invoicing regulations cover a wide range of transaction scenarios, but they do not provide unique rules for every complex VAT situation. Here is how various special scenarios are handled under the current framework:
El Salvador’s e-invoicing regulations cover a wide range of transaction scenarios, but they do not provide unique rules for every complex VAT situation. Here is how various special scenarios are handled under the current framework:
-
Triangulation Transactions: In EU VAT terminology, “triangulation” refers to three-party cross-border transactions. In El Salvador (a non-EU country), there is no direct equivalent of EU triangulation simplifications, and the e-invoicing laws do not mention “triangulation” explicitly. For any multi-party supply chain involving El Salvador, the general rule is that each taxable supply involving a Salvadoran VAT-registered entity must be documented by a DTE from the supplier to its customer. If goods are sold through an intermediary, the intermediary’s sale to the final buyer would also require a DTE. There is no special DTE code or exemption for multi-leg transactions – each leg is invoiced as a normal sale (or transfer) with the appropriate type of electronic tax document. The clearance platform ensures that the tax authority receives data on each step. (One recent change, as noted earlier, is that for export transactions on behalf of a third party, the export invoice must now include the third party’s identification details. This suggests the system is adapting to capture more complex supply chains by linking the parties involved. But aside from that additional data requirement for third-party exports, triangulated transactions are treated via the standard DTE process on each transaction.) [ivacalculator.com] [edicomgroup.com]
-
Chain Transactions and Drop-Shipments: Similar to triangulation, if a chain transaction occurs (e.g., A sells to B, who then sells to C, but goods ship directly from A to C), both the A→B and B→C legs would each need their own DTEs if both A and B are registered in El Salvador. The fact that goods are drop-shipped does not remove the need for invoicing each taxable transfer of ownership. The tax regulations do not provide a special “pass-through” invoice – B cannot simply forward A’s invoice to C. Instead, A would issue a DTE to B, and B would issue a DTE to C, each cleared with the tax authority. If B is not in El Salvador (a foreign intermediary), then A’s sale to B might be an export (documented by an export invoice DTE), and B’s onward sale to C (in El Salvador) could be an import for C or a domestic sale by B if B is registered locally. In all cases, the appropriate DTE (whether a normal invoice or an export invoice) is used by any Salvadoran-tax-registered party in the chain. The electronic system thereby ensures a full audit trail of complex transactions, although no one DTE links all three parties simultaneously – it’s handled through separate documents between each pair of trading partners.
-
Cross-border B2B Services and Reverse Charge: The DTE regime currently focuses on documenting transactions where a Salvadoran entity is the supplier. Inbound services (where a Salvadoran business imports a service from a foreign provider) are not issued as DTE invoices by the foreign supplier (since the foreign company isn’t in the system). Instead, the Salvadoran recipient may have to account for VAT on such imported services via the reverse charge mechanism in their VAT return (as per general VAT law) – but this reporting is outside the scope of the DTE platform. The e-invoicing rules do not explicitly address reverse-charge scenarios, as they do not involve the issuance of an invoice by a local taxpayer. The Salvadoran buyer would likely keep the foreign supplier’s invoice for record purposes and perform any required self-assessment of VAT in their returns. There is currently no specialized “electronic document” for reverse-charge transactions or imported services, and no requirement to upload such invoices to the DTE system. Only when the Salvadoran company on-charges or re-sells services locally would a DTE come into play (documenting the local supply).
-
Zero-Rated and Exempt Supplies: The DTE system is fully capable of handling VAT-exempt or zero-rated transactions, but these are managed through data fields rather than separate processes. The JSON invoice schema includes classifications for tax types and rates. For example, an export sale (which is zero-rated for VAT) is documented by a Factura de Exportación Electrónica (FEXE) DTE indicating a 0% VAT rate on its line items. Likewise, domestic transactions by “excluded” or exempt entities can be documented with a Factura de Sujeto Excluido (FSEE) – a type of DTE used for sales to entities that are not subject to VAT (or specific exempt operations). An FSEE indicates that the transaction is VAT-exempt (no VAT charged) but still provides the necessary details for reporting purposes. Other DTE types cover special cases: for instance, a Comprobante de Donación Electrónico exists to document charitable donations which may be deductible. In all cases, even if no VAT is charged (exempt or 0% transactions), the operations are captured in the DTE system for transparency. The DTE must appropriately flag the exemption or zero-rating, and the tax authority thus receives a full record of those transactions. [ivacalculator.com]
-
Special VAT Regimes (e.g., Small Taxpayer or Simplified Regime): El Salvador’s general VAT law provides that all VAT taxpayers must issue invoices for their sales. We have not found evidence of a separate “simplified invoice” regime that exempts small businesses from invoicing. Instead, the approach has been to support small taxpayers with tools and phased timing (rather than exclude them). The “Otros” taxpayer category, which includes many SMEs and startups, has been given more time and a free platform (see Sections 3 and 12) to ease their compliance burden, but they are still required to comply with e-invoicing by their assigned deadlines. There is no special invoicing for travel agencies or margin schemes indicated in public guidance – such businesses also use DTEs, applying the normal VAT rules (for instance, if a margin scheme were in effect, the invoice might still show the full price and either not break out VAT or indicate a special VAT treatment). In short, no specific accommodations in the DTE technical requirements exist for different VAT regimes; all must use the standard DTE types and include the necessary fields to reflect the nature of the transaction (taxable, exempt, etc.).

9. Archiving & Retention
E-invoices and related electronic documents in El Salvador are subject to strict archiving and retention rules to ensure they remain accessible and unaltered for tax inspection purposes. Key requirements include:
E-invoices and related electronic documents in El Salvador are subject to strict archiving and retention rules to ensure they remain accessible and unaltered for tax inspection purposes. Key requirements include:
-
Retention Period: Electronic Tax Documents must be retained for at least 10 years from their date of issuance. This 10-year retention obligation is set by the Tax Code amendments (Decree 487/2022) and aligns with the statute of limitations for tax audits. Both the digital invoice (the JSON/XML file with the electronic signature) and its graphic representation (e.g. a PDF copy or printed invoice) must be kept. Notably, the tax code specifies a minimum of 10 years, but some guidance suggests maintaining records for up to 15 years to also comply with other regulatory requirements like anti-money-laundering laws. In practice, many businesses are retaining e-invoices for 15 years to be safe, but the tax law’s explicit requirement is ten years. [sovos.com], [taxnews.ey.com] [elsalvador.com], [elsalvador.com]
-
Storage Format and Location: The integrity and format of the archived invoices must be preserved. The Tax Code reforms state that electronic invoices must be stored in the same format and medium as they were issued. This implies that taxpayers should keep the original JSON (or XML) files and not just printed copies or converted formats. The graphic (human-readable) representation of the DTE – typically a PDF or paper printout – should also be stored in the format it was generated and provided to customers. Ensuring both machine-readable and human-readable forms are retained helps guarantee readability and auditability. There is no explicit rule that the data must be stored on servers physically located in El Salvador; companies may use cloud storage or overseas data centers, as long as the records can be made available to the authorities on request and meet security standards. The key is that the archived e-invoices maintain their authenticity and integrity (i.e., the digital signature and content remain intact and verifiable). [sovos.com]
-
Authenticity & Integrity Requirements: Digital signatures are central to guaranteeing document authenticity over time. Each DTE’s digital signature (issued by the DGII’s certification process) ensures that any alteration to the file would invalidate the signature. Taxpayers must make sure that when storing DTE files, the electronic signature and hash (the “Sello de Recepción” and any cryptographic elements from clearance) are preserved. This way, even years later, an auditor can verify that the file is exactly as originally issued and approved, maintaining both authenticity (proving the source/issuer) and integrity (no tampering). The archived files should remain readable (in legible form) for the entire retention period. Given the pace of technology change, this means businesses should plan to migrate or update storage media as necessary and keep software tools to render the JSON/XML into a human-readable form (e.g. maintaining the PDF representations or using software to visualize JSON data).
-
Access for Audits: The Tax Administration (DGII) has broad powers to request and access electronic tax documents for verification. Taxpayers must ensure that stored DTEs can be produced to the authorities upon request, in an intelligible form. In fact, the 2022 reform explicitly gave the DGII rights to access taxpayers’ electronic systems and review the data of electronic tax documents. This could include inspecting the digital files or the accounting systems where they are stored. Therefore, companies should not only keep the files but also be prepared to allow or provide access for audit purposes. Using the DGII’s systems has an advantage in this regard: since every DTE is transmitted to the government, the tax authority already possesses a copy of each invoice (the “the DTEs received by the Tax Administration will prevail over those kept by taxpayers” in any case of discrepancy). Nonetheless, the onus is on the taxpayer to maintain proper archives. Failure to keep invoices for the full retention period or to ensure their legibility/integrity could result in penalties under El Salvador’s general tax rules (e.g. penalties for lack of accounting records). Companies should implement robust archival systems (whether in-house or using the government’s platform for small issuers) and consider data backup and disaster recovery measures to prevent loss of compliance data over the long term.

10. Penalties & Enforcement
El Salvador’s e-invoicing legislation introduces specific penalties to enforce compliance, on top of existing tax penalties. Non-compliance with e-invoicing requirements can lead to significant fines and sanctions, including monetary penalties calculated as a percentage of transaction values. Key enforcement provisions include:
El Salvador’s e-invoicing legislation introduces specific penalties to enforce compliance, on top of existing tax penalties. Non-compliance with e-invoicing requirements can lead to significant fines and sanctions, including monetary penalties calculated as a percentage of transaction values. Key enforcement provisions include:
-
Failure to Issue or Deliver E-Invoices: Not issuing a required electronic invoice (DTE) or not delivering it to the customer is a serious offense. The Tax Code as amended by Decree 487 and related provisions imposes a fine of 50% of the transaction amount (with a minimum of two monthly minimum wages in the commerce sector) for each transaction where a required invoice/DTE was not issued or delivered. This hefty penalty underscores that every sale by a VAT-registered taxpayer must be properly invoiced through the DTE system once obligated. Even before e-invoicing, similar penalties existed for failing to issue paper invoices, and they continue to apply in the electronic era. [consortiumlegal.com], [consortiumlegal.com]
-
Incorrect or Incomplete E-Documents: Issuing a DTE that does not meet the formal requirements (e.g. missing mandatory fields, not following the required format) or transmitting a DTE that doesn’t conform to the prescribed data structure and rules is considered an infraction. The tax authority can levy fines for such non-compliance, though the exact amounts or percentages are determined by regulations. The law empowers the DGII to sanction taxpayers for “issuing documents that fail to comply with established formal requirements” or “transmitting DTEs without the required data structure or conditions”, among other violations. These violations are enforceable under the Tax Code’s penalty regime for electronic invoicing. Essentially, if a company tries to skirt the system by issuing noncompliant invoices (or manipulating the data), it can face fines and possibly other consequences (such as audits or legal action). [sovos.com], [sovos.com]
-
Improper Data Requests (Customer Information): A new category of infraction was introduced in 2024 to protect customers from being asked for unnecessary information. If a business requests personal or tax identification data from a customer in cases where such data is not required by law (for instance, demanding a customer’s ID on a low-value B2C sale that doesn’t meet the criteria), the issuer can be fined 30% of the transaction value, with a minimum of two monthly minimum wages. This penalty, added via Legislative Decree No. 94/2024, applies to both physical and electronic invoices (Articles 239(j) and 239-A(k) of the Tax Code were updated for this). It essentially penalizes forcing unnecessary disclosures on invoices. Businesses must therefore understand when customer information is optional vs mandatory (as described in Section 1) to avoid these fines. [consortiumlegal.com], [consortiumlegal.com] [consortiumlegal.com]
-
Non-Compliance with Platform Use and Deadlines: The DGII can also impose penalties for not adhering to the procedural aspects of the e-invoicing system. For example, failure to comply with specific regulations issued by the Tax Administration regarding DTEs or missing a mandated deadline to start using DTE can lead to sanctions. If a taxpayer does not transition to electronic invoicing by their assigned date, the tax authority may treat invoices issued in any other form as non-compliant, potentially subjecting the taxpayer to the general fine of 50% of transaction value for each non-DTE invoice, or other administrative penalties. There are also provisions for penalizing misuse of the system – e.g., if an entity manipulates or misuses the electronic platform or doesn’t follow the correct process for transmission and approval, that could be considered a violation (for instance, sending DTE data that doesn’t meet the required format or terms is explicitly listed as an offense). [sovos.com]
-
Archiving Violations: The tax code requires taxpayers to retain DTEs (and their printed/PDF representations) for the full retention period (10 years). If a business fails to maintain the required records or cannot produce them during an audit, it may face penalties under the general rules for improper record-keeping. While the exact fine is not specified in the e-invoicing law itself, taxpayers should be aware that not keeping electronic invoices for the mandated time or altering their original format can be penalized. Additionally, if a taxpayer does not report the disposal of its old paper invoices when transitioning to DTE (within 15 business days of their mandatory date), that omission could also result in sanctions as per the 2022 legislation. [taxnews.ey.com], [taxnews.ey.com]
-
Intentional or Fraudulent Conduct: The e-invoicing law reinforces existing penalties for tax evasion and fraud. If a taxpayer deliberately issues invoices outside the system to evade reporting sales, they can be subject to severe penalties, including the 50% of transaction fine and potential criminal consequences for tax evasion. The digital system actually tightens enforcement because the DGII can more easily detect unreported transactions (e.g. by cross-checking DTE records with VAT return data and third-party information). The government has framed e-invoicing as a tool to combat tax evasion, so we can expect strict enforcement. In public statements, officials have emphasized the importance of compliance and signaled that audits will focus on ensuring all required transactions are properly invoiced and reported. [fonoa.com]
All relevant penalty provisions are now integrated into the Tax Code and supporting regulations. For reference, the new penalties for e-invoicing non-compliance were incorporated in Articles 235, 239, and 239-A of the Tax Code (covering failures in issuing DTEs and misuse of customer data). Taxpayers are advised to familiarize themselves with these provisions to avoid inadvertent violations. [consortiumlegal.com], [consortiumlegal.com]
11. Pre-Filled VAT Returns
El Salvador is moving towards leveraging e-invoicing data to simplify tax compliance for businesses. As of 2025–2026, the VAT return process is being enhanced with pre-filled data drawn from the DTE system, although full pre-populated returns are still in development. Key points:

-
Current Status of Pre-Filled Returns: At present, El Salvador does not yet provide fully pre-filled VAT returns to taxpayers, but it has introduced features to significantly streamline the preparation of tax declarations using e-invoice data. The main VAT return (form F-07) now includes Annexes that are automatically populated using the data from electronic invoices (DTEs) submitted to the tax authority. For example, the annexes for taxable and exempt sales, purchase ledger, and withholdings are directly fed by the cleared DTE information: the system aggregates the totals from all the taxpayer’s sales (broken down by tax rate) and inputs them into the draft return annexes. According to local reports, the tax authority claims this automation has reduced the time to prepare the monthly VAT filing to just a few minutes, since most data is pre-filled. Taxpayers can access the DGII’s online system to review the compiled data before submitting their return. This is a form of “pre-filled return” initiative, though the taxpayer remains responsible for verifying the data and adding any information not captured by DTE (for instance, transactions outside the scope of DTE or adjustments).

Planned Implementation: El Salvador’s e-invoicing rollout was conceived with the long-term goal of enabling pre-filled tax declarations, following the example of countries like Chile. The clearance model provides the government with real-time data on sales and purchases, paving the way for the DGII to draft returns for taxpayers. As more taxpayers come fully online with DTE, the DGII is expected to expand pre-filling capabilities. Indeed, one source notes that El Salvador’s e-invoice system was designed with “future plans to introduce pre-filled VAT returns” once the DTE regime is mature. This would mean the tax authority could provide taxpayers with a draft VAT return (or at least the VAT ledger totals) based on DTE data, which the taxpayer would then confirm or adjust. [vatcalc.com]
-
Scope of Pre-Filled Data: Already, certain fields in the VAT return are effectively pre-filled via the DTE data integration. Sales to final consumers and to taxable persons are recorded through DTEs and reflected in the sales annexes of the VAT return without the need for the taxpayer to manually compile those figures. Similarly, purchases for which suppliers have issued DTEs (i.e., the taxpayer’s incoming invoices) are captured in the purchase annex. The system can also account for withholding receipts (CRE DTEs), which affect the VAT payable by the supplier or provide credit to the customer. However, at this stage the taxpayer typically must still review the data and input any additional information not in the DTE system (such as certain adjustments, imports, or other operations that might not have been covered by DTEs). So while not a 100% hands-off pre-filled return, the heavy lifting of compiling transaction data is done by the tax authority’s systems. [ivacalculator.com]
-
Taxpayer Input vs. Auto-Calculated Fields: In a future fully pre-filled return scenario, the goal would be for fields like total taxable sales, total VAT, and total credits to be auto-calculated from DTE submissions. Taxpayers might then only need to add information for transactions not captured (if any) or make corrections. Already, El Salvador’s system provides an “inconsistency dashboard” where taxpayers can see any mismatches between their DTE data and what would be reported on their VAT return. Fields that are currently pre-filled (via the DTE-populated annexes) include: the breakdown of sales by VAT rate (standard 13% vs exempt) and the total output tax due, and the total input tax credit from supplier DTEs. Fields that likely still require manual input could include adjustments, special credits, or non-standard transactions (like import VAT paid at customs, or any transaction that didn’t go through DTE). Over time, as the system evolves, even those might be integrated if the tax authority links customs systems and other databases to the e-invoice system. [ivacalculator.com], [ivacalculator.com]

Existence of Pre-Filled Returns: To date, El Salvador has not formally implemented pre-populated VAT returns in the sense of sending taxpayers a complete pre-prepared return. Taxpayers still log into the online tax portal and file their monthly VAT return (Form F-07). The change is that much of the information is now preloaded from DTE records, reducing manual work. There have been no official announcements of a fully automatic filing system yet, but the trend is towards greater pre-filling. Taxpayers should double-check the auto-populated data each period and reconcile it with their own records, since any errors in e-invoice submissions (or any missing invoices) would directly impact the draft figures on file. In summary, pre-filling of VAT returns is emerging as a benefit of the e-invoicing system, but taxpayers remain responsible for reviewing and officially submitting the returns. The DGII may in the future move to a system of proposed VAT returns (similar to Chile’s or Italy’s models), using DTE data – a development to watch for.
12. Impact on SMEs and Startups
The e-invoicing mandate in El Salvador has significant implications for small and medium-sized enterprises (SMEs) and startups, and the government has taken measures to ease the transition for these businesses. Below is an analysis of the effects on SMEs, including any simplified regimes, phased implementation, support programs, and operational impacts, based on recent external sources:

-
Phased Onboarding and Thresholds: Recognizing the challenges for smaller businesses, El Salvador adopted a phased rollout. Large taxpayers were mandated first, followed by medium, then small businesses, spreading compliance over 2023–2025 (see Section 3). This gave SMEs more time to prepare and budget for the change. The DGII categorized “Otros” taxpayers (generally smaller businesses) separately and scheduled their mandatory dates later. By April 2024, only about 20% of small taxpayers had switched to e-invoicing, compared to over 90% of large companies, reflecting the deliberate slower pace for SME integration. The government’s goal was full SME adoption by May 2025, but some very small enterprises were effectively given until late 2025 or into 2026 to come on board. This staged approach acted as a de facto threshold, prioritizing bigger businesses first. However, there is no permanent revenue threshold exemption – even micro-businesses under standard VAT law must eventually use DTE if they issue VAT invoices. (If a business is so small that it is not required to register for VAT at all, then it remains outside the system, but if it’s a registered VAT contributor, e-invoicing will apply.)

-
Simplified Regimes: El Salvador’s tax system does have a small taxpayer regime known as the “Régimen de Pequeño Contribuyente,” but such taxpayers (who typically pay a flat tax and do not issue tax credit invoices) may not be part of the primary DTE system since they do not issue standard VAT invoices. The e-invoicing mandate chiefly concerns standard VAT-registered businesses. Therefore, to the extent very small businesses operate under a simplified regime that doesn’t involve issuing VAT invoices, those businesses wouldn’t be issuing DTE invoices. For most practical purposes, though, any business that issues invoices to charge VAT is considered a contributor and must implement DTE. There is no mention in public sources of a separate simplified electronic invoice for small taxpayers; instead, small businesses use the same DTE types (FE, CCFE, etc.) when they are required to invoice. The free government e-invoicing portal (Sistema de Facturación gratis) is a form of simplification specifically aimed at micro and small enterprises, allowing them to comply without investing in expensive software.

Government Support and Tools: The Ministry of Finance has provided support for SMEs in several ways. First, as noted, a free web-based invoicing system is available for qualifying small businesses (those with average monthly sales up to $10,000 and ≤100 invoices per month). This system, hosted at factura.gob.sv, enables small businesses to manually create and issue DTEs and automatically handles digital signing and transmission to DGII. The government also provides free digital certificates to all taxpayers (the electronic signature required for signing DTEs is issued by the DGII at no cost). Additionally, training and support have been offered: DGII and local industry groups have run webinars, published FAQs, and provided user manuals to help SMEs understand and adopt e-invoicing. Officials have noted that notifications to small businesses are sent well in advance (often a quarter before the deadline) to give them time to prepare and test their systems. There are also partnerships with software vendors and accounting firms to assist SMEs in implementation; for instance, tech firms and consultants (some stemming from the pilot program) have been actively helping small enterprises (from “pupuserías to clinics,” as one expert noted) to migrate to digital invoicing, often offering low-cost cloud solutions and training sessions. So, while the mandate is comprehensive, SMEs have access to simplified tools and instructional support to reduce the burden.

Compliance Costs: Upfront costs for SMEs can include investing in compatible software or modifying existing billing systems, as well as training staff. However, the availability of the government’s free platform means that a small business could comply with minimal financial cost if it has internet access. Private e-invoicing solutions for SMEs in El Salvador reportedly start at around ~$100 per year for basic packages. The digital certificate and use of the government’s API are free of charge, so costs are mainly related to software and possibly service provider fees if the company opts for a commercial solution. There may also be some costs for upgrading IT infrastructure or devices (to ensure reliable internet and computer access), and ongoing costs if the company chooses value-added services (like cloud archival or ERP integrations from a provider). The consensus in local business media is that while there is an initial investment of time and resources, these are offset by long-term savings (on paper, printing, storage, and administrative labor).

Operational Impacts: On the plus side, e-invoicing can improve efficiency and cash flow for SMEs. Because invoices are validated in real time, errors that might have caused downstream VAT rejections or audits can be caught immediately and corrected, reducing the risk of future penalties or delayed tax refunds. Automated validation means fewer disputes with customers over invoice correctness, and the electronic format means invoices reach customers faster (improving the payment cycle). Also, with data flowing into the tax authority, some processes like VAT return preparation are streamlined (as noted, the system can auto-calc [azteq.software]
