Briefing Document & Podcast: E-Invoicing and E-Reporting in Paraguay

1. Scope of the Mandate

• Comprehensive Coverage of Transactions: Paraguay’s e-invoicing mandate covers virtually all transaction types. Under Decree 872/2023, electronic tax documents (Documentos Tributarios Electrónicos, DTE) must be used for domestic B2B and B2C sales, exports of goods (B2E), cross-border services (B2F), and B2G transactions. Any sale or service with tax implications must be documented via SIFEN (the National Integrated Electronic Invoicing System) once a taxpayer is obligated. This includes transactions that are VAT-taxable, exempt, or non-taxable – all require an official invoice or receipt, now in electronic form. [lexparaguaya.com], [taxathand.com] [set.gov.py]
• E-Invoicing Obligations: Mandated taxpayers must issue their invoices, receipts, and other tax documents exclusively in electronic format via SIFEN (also known as e-kuatia), following the national schema and validation process. Paper or manual invoices are no longer valid once a taxpayer falls under the mandate. Any invoice not issued through the approved electronic system is not legally recognized for tax or accounting purposes. [flick.network] [flick.network], [flick.network]
• B2C Transactions and Thresholds: Electronic invoices are required for B2C (business-to-consumer) operations as well. For ordinary retail sales to final consumers, electronic receipts (boleta electrónica, a simplified e-invoice) are used. Identification of the customer on B2C e-invoices is mandatory when the transaction value exceeds certain thresholds: from 1 January 2024 a threshold of PYG 35 million (≈ USD 4,700), lowered to PYG 7 million (≈ USD 900) from 1 January 2025, meaning high-value consumer sales must capture the buyer’s identity. Below those amounts, a buyer can remain “consumidor final” (anonymous), though identification is still allowed if needed. [fonoa.com], [taxathand.com] [lexparaguaya.com], [lexparaguaya.com]
• B2G (Government Transactions): Electronic invoicing is required for B2G transactions (sales to government entities) as part of the mandate’s scope. In fact, all suppliers to the State (public sector vendors) must issue their invoices and receipts only in electronic form by 2 January 2026. This ensures full adoption of e-invoices in public procurement (B2G). [comarch.com], [flick.network]
• Cross-Border Transactions: The framework explicitly accounts for cross-border deals. Exports (B2E) of goods must be accompanied by an Electronic Export Invoice, which must be issued (and approved in SIFEN) before the customs export clearance is finalized and before the goods leave Paraguayan territory. This export e-invoice supports the cancellation of the final export declaration and serves as the VAT zero-rated invoice for the export. Cross-border B2B services (B2F) are also within scope – Paraguayan providers must issue an electronic invoice to foreign clients and identify the recipient (with name/ID, since “unidentified” recipients are not accepted for B2B, B2F, or B2G transactions). If a Paraguayan business imports goods or receives services from abroad, the local buyer must still account for these transactions: the system allows “Comprobante Electrónico de Importación” (electronic import document) to record imports, and “Autofactura Electrónica” (self-issued invoice) for purchases from unregistered suppliers. These special electronic documents ensure cross-border transactions are captured in the electronic system even when the supplier is foreign or not registered for VAT. [taxathand.com], [lexparaguaya.com] [taxathand.com] [lexparaguaya.com], [imaginesoft.io]
• Self-Billing (Autofactura): Self-billing is permitted and built into SIFEN. Paraguay’s DTE types include the Autofactura Electrónica (self-invoice) for scenarios where a buyer (a VAT-registered taxpayer) purchases from a person not obligated to issue invoices (e.g. an unregistered individual or a foreign supplier). In such cases, the buyer issues an official electronic self-invoice via SIFEN to document the transaction. The self-invoice carries all required details of the transaction. By regulation, the self-invoice cannot be used to claim VAT credit (since the original seller was not charging VAT) and does not need to be physically signed by the supplier. Nonetheless, it must be transmitted and approved in SIFEN like any other DTE. [lexparaguaya.com], [imaginesoft.io] [lexparaguaya.com]
• Triangulation & Chain Transactions: The e-invoicing rules do not prescribe special document types or exceptions for multi-party transactions (such as triangulation or chain transactions), beyond the normal requirement that each taxable supply be invoiced by the responsible supplier. In practice, each leg of a chain transaction must be covered by an electronic invoice issued by the supplier responsible for that leg. The system’s “Nota de Remisión Electrónica” (electronic dispatch/shipping note) is available to accompany goods in transit, ensuring documentation of goods delivered to third parties on behalf of the buyer or other chain scenarios. No unique “triangulation” e-invoice exists – each sale is invoiced as usual. If a local company is acting as intermediary in a triangular deal, it will issue a standard e-invoice for its sale and rely on the dispatch note to track direct delivery of goods to the final customer. [lexparaguaya.com]
• Special VAT Regimes: The Paraguayan e-invoicing framework extends to special regimes as well. For example, taxpayers under the Simplified Regime for small businesses (the “RESIMPLE” regime) have a dedicated DTE type called “Boleta RESIMPLE Electrónica” for their sales. Other special documents include Electronic Bill of Exchange Invoice (Factura Cambiaria Electrónica) for factoring/secured transactions, Individual Income Tax (IRP) Electronic Receipts for occasional sales by individuals not otherwise invoicing, Electronic Donation Receipts, etc., all of which are defined in the e-invoicing regulations. Thus, the mandate is broad in scope, spanning regular VAT invoices, government invoices, simplified invoices, export/import documentation, and various niche tax documents – effectively covering all scenarios where a tax-related document is needed.

2. Taxable Persons in Scope

• Mandatory for All Registered Businesses: All Paraguayan VAT-registered businesses will ultimately fall under the e-invoicing mandate, though the rollout is phased by taxpayer size/category. The largest taxpayers (“grandes contribuyentes”) have been using e-invoicing since 2022–2023, and medium and small businesses are being phased in through 2024–2026. By 2025, all companies incorporated in Paraguay were slated to use the electronic invoicing system, and subsequent schedules have extended final phases into 2026 (see Timeline below). In effect, any entity with a local tax ID (RUC) that issues VAT documents will be required to comply on its designated date. This includes corporate entities and sole proprietors doing business in Paraguay. [imaginesoft.io], [imaginesoft.io] [taxsummaries.pwc.com] [lexparaguaya.com]
• Non-Established Taxpayers: Foreign or non-resident companies that have a fixed establishment or VAT registration in Paraguay (e.g. a local branch or subsidiary) are subject to the same e-invoicing obligations as local companies. Such entities must implement SIFEN compliance by their assigned deadlines, ensuring their systems can generate and transmit DTEs from their Paraguayan operations. Foreign companies without any local tax registration (i.e. selling cross-border into Paraguay without a local establishment) are not directly part of the SIFEN system, since only entities with a RUC can be onboarded. In those cases, the obligation shifts to the local customer to properly document the transaction (e.g. via a self-invoice or import document) if needed for VAT accounting. [imaginesoft.io] [lexparaguaya.com], [imaginesoft.io]
• Exemptions or Special Cases: There are no broad exemptions by sector or size – the intent is to bring all taxpayers into SIFEN eventually. However, the rollout has been calibrated by taxpayer size and type, which functionally defers the obligation for smaller companies (giving them additional time to prepare). Very small businesses under the RESIMPLE tax regime are also included in the mandate, but they use a simplified e-receipt format and typically fall into later adoption groups. Optional/Voluntary usage of e-invoicing was allowed during the early rollout – businesses not yet mandated could opt in to SIFEN. Many did so, and by law those who voluntarily adopted are required to continue using e-invoices exclusively (they cannot revert to paper). As of now, few carve-outs exist: the only exclusions explicitly noted are the “Virtual Withholding Voucher” (a retention certificate) which is not yet an electronic DTE, and some individuals not in business (though even individuals have an IRP e-document for certain cases). Essentially any taxable person issuing invoices in Paraguay is in scope or will be soon, absent a specific exception.

3. Implementation Timeline

• 2017 – Legal Basis Established: The e-invoicing initiative began with Decree No. 7795/2017 (27 Sept 2017), which created SIFEN as the country’s electronic invoicing system. Over the next few years, the tax authority (formerly SET, now DNIT – Dirección Nacional de Ingresos Tributarios) ran pilot programs and defined technical standards. [taxsummaries.pwc.com]
• 2019–2021 – Pilot and Voluntary Phases: Paraguay conducted a controlled pilot and voluntary adoption phase. A pilot program was launched (initially ~246 companies involved), followed by an “Adhesión Voluntaria” stage where additional taxpayers were allowed to join SIFEN on a voluntary basis. Regulatory foundations were laid by General Resolution 90/2020 and General Resolution 105/2021 which designated pilot participants and early adopters as electronic issuers, and set dates for them to switch fully to e-invoicing. General Resolution 105/21 mandated that pilot and voluntary adopters had to transition to exclusive e-invoicing by 1 July 2022. [tpa-global.com] [set.gov.py], [set.gov.py] [set.gov.py]
• 2022 – First Mandatory Wave: From 1 July 2022, those initial adopters (pilot/volunteers) became legally required to issue all invoices and tax documents electronically. This marked the end of the purely voluntary phase and the start of mandatory e-invoicing for designated taxpayers. [set.gov.py]
• 2023–2024 – Phased Rollout of Groups 1–10: Paraguay’s tax authority published an implementation calendar (via RG 105/21 and updates) for a gradual rollout to ten groups of taxpayers between 2023 and late 2024. The groups were generally organized by taxpayer size and sector. According to this schedule, Group 1 went live on 2 January 2023, and additional groups followed roughly each quarter: e.g. Group 2 on 3 April 2023, Group 3 on 3 July 2023, etc., through Group 10 on 1 October 2024. This phased approach allowed businesses to adapt in waves rather than all at once. By October 2024, thousands of medium and large companies had become obligated e-invoice issuers. Notably, during this period the President issued Decree 872/2023 (18 Dec 2023) – an updated e-invoicing regulation effective 1 January 2024 – replacing the older 2017 decree to refine and expand the legal framework for SIFEN’s full deployment. [tpa-global.com] [taxathand.com], [fonoa.com]
• 2024 – Expansion to All Incorporated Businesses: In early 2024, General Resolution DNIT No. 01/2024 extended mandatory e-invoicing to all legal entities registered in the RUC system, i.e. essentially all newly registered companies were immediately required to use e-invoices and no longer issued paper receipts. (This rule was slightly adjusted by subsequent resolutions – see below.) Throughout 2024, voluntary uptake continued for those not yet mandated. [edicomgroup.com], [set.gov.py]
• 2025–2026 – Final Mandatory Rollout (Groups 11–18): To cover remaining taxpayers (primarily medium and smaller businesses), the DNIT issued General Resolution No. 21/2024 in late 2024, establishing a new schedule of eight waves from 2025 through 2026. Group 11 under this schedule began 3 March 2025, and Group 12 on 2 June 2025, with additional groups every quarter: 1 Sep 2025 (Group 13), 1 Dec 2025 (Group 14), 2 Mar 2026 (Group 15), 1 June 2026 (Group 16), 1 Sep 2026 (Group 17), and the final Group 18 on 1 Dec 2026. Each wave brings hundreds more taxpayers into SIFEN (about 500 per group) cumulatively covering around 4,054 taxpayers by end-2026. By that point, the vast majority of Paraguayan businesses will be under mandatory e-invoicing, completing a nationwide rollout. [comarch.com], [edicomgroup.com] [comarch.com], [comarch.com]
• Key Interim Milestones: As part of the 2025 plan, all new legal entities registered from 1 April 2025 onward have to issue invoices electronically from the start (no paper) – effectively shifting the “default” for new businesses to e-invoicing. Additionally, as noted, from 2 January 2026, all Government suppliers must use e-invoices. During the rollout, the tax authority allowed a one-time extension request: a taxpayer could apply at least 30 business days in advance to defer its go-live to the next group if absolutely unready. However, this only shifts the obligation by one phase. After each group’s deadline, pre-printed paper invoices or old “self-printer” authorizations become invalid – those companies must use DTEs exclusively from that date onward. [comarch.com], [flick.network] [comarch.com]
• Legislative Adoption & Grace Periods: Decree 872/2023, effective Jan 2024, provided updated regulation and did not include additional grace periods for compliance beyond what DNIT schedule allows. However, enforcement in early phases was somewhat lenient: the tax authority had a transitional period where fines for late reporting were temporarily waived, which ended on 31 October 2024. After that date, normal penalty enforcement began (see Penalties & Enforcement). Overall, the timeline shows a clear trajectory: pilot (2019–2021), voluntary (2021–2022), and mandatory phases spanning 2023–2026, culminating in full nationwide e-invoicing by end of 2026.

4. Technical & Functional Requirements

• E-Invoice Format (XML Schema): Paraguay’s e-invoices are generated in a local XML format defined by the tax authority (DNIT). Each electronic tax document (DTE) must conform to the SIFEN XML schemas and specifications published by the DNIT. The system distinguishes between a “Documento Electrónico (DE)”, which is an e-document created and digitally signed by the issuer’s system but not yet approved, and a “Documento Tributario Electrónico (DTE)”, which is the final, validated e-document after SIFEN approval. Only DTEs have full legal validity for tax and commercial purposes. [edicomgroup.com], [edicomgroup.com]
• Mandatory Data Fields: All legally required invoice content must be present in the electronic format. This includes standard invoice information and tax data: e.g. unique invoice number and “timbrado” authorization code, date/time of issuance, the supplier’s and customer’s tax identification (RUC) and details, item descriptions and quantities, unit prices, applicable VAT rates (5% or 10% or exemption) and amounts, totals, and other metadata. The e-invoice regulations expand on definitions from the VAT law (Law 6380/2019) to ensure each electronic invoice indicates when the obligation arises and that required documentation is provided for each sale. The data model also includes fields for specific document types (e.g. distinguishing a standard invoice vs. an export invoice, credit note, etc.), and references to related documents when needed (for example, a credit note must reference the invoice it adjusts via the original invoice’s unique code). All DTEs must embed a unique Control Code (Código de Control, “CDC”) of 44 alphanumeric characters assigned by SIFEN upon validation. This code, akin to a unique identifier or hash, guarantees uniqueness and authenticity of each approved document. [imaginesoft.io] [taxathand.com] [lexparaguaya.com], [lexparaguaya.com] [lexparaguaya.com]
• Digital Signatures & Security: Every e-invoice (DE) must be digitally signed with a qualified electronic signature before transmission. Issuers obtain a digital certificate from an approved certification authority in Paraguay, which is used to sign the XML and ensure the document’s authenticity, integrity (no tampering), and non-repudiation. The system also uses the control code (CDC) to generate a QR code that is printed on the human-readable representation (called KuDE) of the invoice, so that anyone can scan and verify the e-invoice’s status/details via the tax authority’s portal. These security measures ensure that any alteration of an approved invoice would be detectable, and that recipients or auditors can confirm authenticity via the QR or CDC. [edicomgroup.com] [lexparaguaya.com]
• Validation Rules: SIFEN imposes automated validation checks on each electronic document. Submitted XML files are scanned for schema compliance, completeness of mandatory data fields, correct arithmetic calculations of tax and totals, valid digital signature, and valid issuer/recipient RUC numbers, among other business rules. Only if all validations pass does SIFEN register the document and mark it as an official DTE (approved electronic tax document). If a document fails validation, it is rejected, and the issuer must correct any errors and re-submit. [imaginesoft.io]
• E-Reporting Data and Format: Paraguay’s model is essentially a “clearance” system where the e-invoice itself serves as the reporting mechanism – the content of each DTE is transmitted to the tax authority in real time or near-real-time (within a maximum of 72 hours; see Section 6). Thus, the “e-reporting” format is not separate from the e-invoice format – it’s the same XML file containing all invoice data that is sent to SIFEN. There is no distinct periodic “ SAF-T” or summary report for e-invoicing; instead, each invoice’s data is reported individually and instantly (or within 3 days) to the tax authority. The SIFEN technical documentation defines the required schemas for these submissions (covering all DTE types and any associated events like cancellations or acknowledgments).
• Additional Technical Elements: The system uses “Eventos” (events) to handle specific processes or changes in invoice status. For instance, there are event messages for invoice acceptance/rejection by the buyer, cancellation requests, and other status updates which are also transmitted to SIFEN and linked to the original DTE. SIFEN also introduced new categories of DTEs (as noted above) to capture transactions like donations, simplified regime sales, tickets for public events, etc., which have their own data field requirements as specified in the official technical documentation. In summary, the technical framework demands strict adherence to the SIFEN XML format, inclusion of all regulatory data fields, use of digital signatures, and compliance with SIFEN’s validation rules to ensure each e-document is complete and reliable.

5. Correction of Errors in E-Invoices and E-Reporting

• Correcting E-Invoices (Cancellations & Credit Notes): The e-invoicing system provides defined procedures for handling errors on issued DTEs. If an error is discovered shortly after issuing an e-invoice, the issuer has a 48-hour window (from SIFEN approval time) to cancel the invoice directly via SIFEN. Within this period, the supplier can initiate a “cancellation event” in the system (also known as an Anulación), effectively invalidating the DTE. This is only permitted if the buyer has not yet relied on the invoice for tax credit. [rsa.com.py], [rsa.com.py]
• If more than 48 hours have passed since approval, a direct cancellation is no longer allowed. In that case, any errors must be corrected by issuing an Electronic Credit Note (Nota de Crédito Electrónica) referencing the original invoice. Credit notes in SIFEN are linked to the invoice they adjust by the invoice’s CDC code, and they can reduce or nullify the original invoice’s amounts. The credit note must include the same core information as the invoice (notably, the currency and parties) and indicate the reason for the adjustment. By regulation, only the original seller can issue a credit note (self-issued adjustments by buyers are not allowed except via self-invoice for special cases). If both parties are e-invoice users, the buyer’s consent is required for credit notes: the framework introduced a mandatory “Consentimiento” event that the buyer must register for an electronic credit note to take effect. This ensures the buyer acknowledges the reduction in tax credit or expense, preventing unilateral changes. Once approved by SIFEN (and consented to, if applicable), the credit note serves to correct the original error. For increases in the invoiced amount or other post-issuance charges, an Electronic Debit Note is used, similarly tied to the original invoice (debit notes do not require buyer approval since they increase the buyer’s liability, not reduce it). [rsa.com.py], [rsa.com.py] [lexparaguaya.com], [lexparaguaya.com] [taxathand.com], [lexparaguaya.com] [lexparaguaya.com]
• After correcting an invoice via credit or debit note, the corrected data is automatically reported to the tax authority through the DTE system. If needed, the supplier may re-issue a new invoice for the correct amount/details after cancelling or adjusting the erroneous one, ensuring that the official record in SIFEN reflects accurate information. Resubmission of corrected invoices simply means issuing a new DTE (with a new unique number), since original DTEs cannot themselves be edited once approved – they can only be cancelled or adjusted via the above procedures. [rsa.com.py], [rsa.com.py]
• Correcting E-Reporting Errors: Because each invoice is individually reported, there is no separate “summary report” to amend in most cases. If a taxpayer fails to transmit an invoice on time or submits incorrect invoice data, the remedy is to submit the missing/corrected invoice as soon as possible. Late transmission beyond the permitted window (72 hours) may incur penalties (see Section 10) but the system will still accept and register the late DTE once submitted. For periodic electronic reports outside SIFEN (such as the electronic ledgers required by RG 90/2021 – see Section 6), any needed correction or amendment must be made by resubmitting the corrected data or filing an adjustment via the tax portal Marangatu. For example, if a monthly sales report was filed with errors, the taxpayer would correct their records and update the submission in Marangatu as per DNIT’s procedures (potentially by an amended submission or by including adjustments in the next period’s report, depending on the type of error and DNIT’s guidance). In summary, error correction in the Paraguayan system revolves mainly around cancelling or adjusting the original electronic invoice via credit/debit notes. The integrated nature of SIFEN means that any correction to an e-invoice inherently corrects the reported data to the tax authority, eliminating separate notification forms in most cases. Only in instances where an error pertains to a summary declaration (VAT return) or a failure to report at all would a formal notification or revised filing be necessary. [evendeha.com.py]

6. Transmission & Workflow

• Clearance Model: Paraguay operates a clearance e-invoicing model via the central platform SIFEN. All e-invoices and e-reports are transmitted to the tax authority (DNIT) either in real-time or near-real-time for clearance. Taxpayers have two modes: pre-validation (send the invoice to SIFEN before delivering it to the customer, obtain immediate approval and CDC) or post-validation (issue the invoice to the customer first and then report it to SIFEN within a short window). In Paraguay’s case, post-validation is allowed with a maximum deadline of 72 hours after issuance. This means an invoice must be transmitted to DNIT within 3 days of issuance if not cleared instantly. If a business opts for pre-clearance, SIFEN returns validation immediately via API (synchronous mode) along with the CDC code; in post-validation, the business must still ensure the DTE reaches SIFEN and passes validation within 72 hours.
• Transmission Process: Authorized e-invoice issuers connect to SIFEN via web services/APIs. Larger companies typically integrate their ERP or billing software directly with SIFEN’s API, or use an intermediary solution provider certified by DNIT (often called “Proveedores de Servicios de Facturación Electrónica” (PSFEs)). Smaller taxpayers may use the “e-Kuatia’i” web portal, a free, DNIT-provided online invoicing tool (designed for low volume issuance). In practice, the workflow is: [imaginesoft.io], [imaginesoft.io]
  • The taxpayer’s system generates the invoice in XML format with all required data.
  • The invoice XML is digitally signed using the taxpayer’s digital certificate.
  • The signed XML is transmitted to SIFEN (either instantly or batched, via secure REST API connection). [imaginesoft.io]
  • SIFEN validates the document. If valid, it assigns the CDC (control code) and marks it as approved (now a DTE). If invalid, a rejection code is returned and the issuer must correct and resend. [imaginesoft.io]
  • Once approved, the issuer can deliver the invoice to the buyer: If the buyer is also an electronic user, the seller typically sends the DTE via system integration (web service), or provides it by email or a download link, and the buyer must formally acknowledge it by registering a “Conformidad” (acceptance) or “Rechazo” (rejection) event in SIFEN. If the buyer is not yet electronic, the seller must give a printed or PDF copy (KuDE) of the e-invoice or otherwise make it available for download, as that serves as the buyer’s record. In either case, the official record resides in SIFEN and both parties can consult it online.
  • The invoice data is automatically stored in DNIT’s databases and available for tax control or audit. The issuer and recipient must also retain their copies (see Section 9).
• Interoperability: The Paraguayan system is centralized (clearance model), not a decentralized network like PEPPOL. Interoperability is achieved by virtue of all issuers using a unified platform (SIFEN) and format. There is no reliance on third-party networks for inter-company exchange – the tax authority’s platform is the hub for validation and exchange. However, accredited service providers (software companies or integrators) can assist taxpayers by providing interfaces or integration services that are certified to communicate with SIFEN’s API. These providers must conform to DNIT’s specs and are often used by larger firms to streamline compliance. [imaginesoft.io]
• Deadlines and Reporting Frequency: E-invoices must be sent for clearance in real-time or within T+3 days of issuance (where T = invoice date). In practical terms, Paraguay’s system does not require separate periodic (e.g. monthly) invoice listing because each invoice is individually reported. However, during the transition period, taxpayers not yet on SIFEN had to continue reporting their sales/purchases via the Marangatu system. A prior regulation (RG 90/2021) required electronic upload of sales and purchase records to the tax authority’s portal within set deadlines (in effect a form of “e-reporting”). This was a stop-gap measure parallel to e-invoicing. For instance, by late 2024 DNIT was enforcing a fine of PYG 100,000 for each instance of failing to timely submit these electronic ledgers of invoices (reports) in Marangatu. As SIFEN reaches full coverage, such separate reporting will likely be phased out, since approved DTE data flows automatically into DNIT’s systems continuously. No monthly summary of invoices is needed for SIFEN users beyond the normal VAT return, as DNIT already has invoice-level data in near real time.

7. Self-Billing

• Permitted and Integrated: Self-billing (buyer-issued invoices) is explicitly permitted in Paraguay and integrated into the e-invoicing platform. The Autofactura Electrónica is a recognized DTE type (code “DE-4”) for self-issued invoices. It is used typically when purchasing from suppliers who are individuals or entities not registered for VAT or not obligated to invoice. For example, if a company buys goods from a small farmer or an individual, or acquires services from a foreign provider with no local invoice, the Paraguayan buyer issues an electronic self-invoice through SIFEN to document the transaction for tax purposes. [imaginesoft.io], [imaginesoft.io] [lexparaguaya.com], [imaginesoft.io]
• Use of Platform: Self-billing invoices must be issued via SIFEN just like any other e-invoice. The buyer prepares the invoice in the standard XML format (with the buyer as the issuer and the unregistered seller’s details as the “supplier” field) and transmits it to SIFEN for validation and approval. Once approved, the self-invoice gets a CDC code and is stored in SIFEN, fulfilling the buyer’s obligation to document that purchase. Thus, any self-billing must use the e-invoicing platform – paper self-invoices or offline documentation would not meet the requirement once the buyer is an obligated electronic issuer.
• Approval and Content: In self-billing, since the buyer is the issuer, no separate supplier approval is required (the supplier is not on the platform). The content requirements for a self-invoice mirror those of a normal invoice, except that it indicates it is “Autofactura” and identifies the supplier by name/ID (if available) or other acceptable reference. Importantly, by rule the buyer cannot claim VAT credit on a self-invoice (because the transaction did not involve VAT charged by a registered supplier). Additionally, self-invoices are not required to be physically signed by the supplier – in fact, printing is optional since the electronic version is authoritative. [lexparaguaya.com]
• Restrictions and Notifications: The use of self-billing is limited to specific scenarios allowed under tax law (e.g., purchases from non-registered persons). There are no special notification obligations to the tax authority beyond issuing the self-invoice itself, as its issuance through SIFEN inherently notifies the DNIT. The buyer should ensure to follow any specific motive codes or references required in the self-invoice to explain why it’s being self-issued (for instance, referencing the legal reason, such as “Compra a no contribuyente” – purchase from a non-taxpayer). Outside those permitted cases, self-billing should not be used to replace standard invoicing by registered suppliers.

8. Triangulation & Special Scenarios

• Triangulation & Chain Transactions: The Paraguayan e-invoicing rules do not carve out separate processes for multi-party or chain transactions; instead standard e-invoicing requirements apply to each leg of a transaction chain. Each taxable supply between two parties should be covered by an electronic invoice from the seller to the buyer. If goods are delivered directly from an initial supplier to a final customer on behalf of an intermediate seller (a common “triangulation” scenario), the intermediate seller would still issue a DTE to its customer and likely utilize an Electronic Dispatch Note (Nota de Remisión Electrónica) to document the shipment from the first supplier to the end-customer. The dispatch note is one of the DTEs defined in the system and ensures that goods in transit are properly documented even if the invoice is issued by a different party. Thus, triangulation is accommodated through the use of multiple DTEs (invoices for each sale and dispatch notes for the physical movement). [lexparaguaya.com]
• Cross-Border Reverse Charge Scenarios: For cross-border transactions where a foreign entity sells to a Paraguayan business without a local establishment, the foreign supplier is not on SIFEN, so the Paraguayan buyer must self-document the purchase. If it’s an import of goods, the import will be recorded via customs and an optional Comprobante Electrónico de Importación DTE can be generated for record-keeping. If it’s an imported service or any purchase from a non-resident without invoice, the Paraguayan buyer can issue an Autofactura Electrónica (self-invoice) as described above. In both cases, the local buyer also accounts for VAT via reverse charge (as per general VAT rules) in its VAT return. The e-invoicing mandate does not alter the tax treatment of these transactions; it simply provides electronic means (import receipts or self-invoices) to record them when needed. [lexparaguaya.com]
• Zero-Rated & Exempt Supplies: Zero-rated (export) transactions and VAT-exempt supplies are fully encompassed by the e-invoicing system. As noted, exporters must issue Electronic Export Invoices prior to the export, which serve as the supporting document for zero-rated sales. For domestic exempt supplies or transactions outside VAT’s scope, the taxpayer still issues an electronic invoice or receipt (with the VAT category indicated as exempt or non-applicable). Law 6380/2019 obligates documentation of all sales – taxed or not – and the e-invoice format supports marking line items or entire invoices as “exento” (exempt) or “no gravado” (non-taxable) as appropriate. These exempt/zero-rated invoices go through SIFEN like any other DTE. [taxathand.com], [lexparaguaya.com] [set.gov.py]
• Special Cases and Local Nuances: Some unique Paraguayan scenarios are addressed by specific DTE types: e.g. Electronic Income Receipt for Individuals (Comprobante Electrónico de Ingreso IRP) is used by individuals who aren’t regular VAT-registered sellers but occasionally sell goods or assets that are subject to personal income tax. This allows such transactions to be recorded electronically even though the seller isn’t a business issuing VAT invoices. Another local nuance is the requirement of buyer consent (via an event in SIFEN) for credit notes (negative adjustments) between e-invoicing parties, as described earlier – this ensures both sides agree on any change in the taxable amount. Overall, Paraguay’s framework has been designed to handle the full variety of scenarios by defining an extensive list of electronic document types and supplementary “events”, rather than leaving gaps in which paper processes would apply.

9. Archiving & Retention

• Mandatory Retention Period: All electronic invoices and related electronic documents must be archived for at least 5 years for tax control purposes. This 5-year retention requirement aligns with the general statute of limitations for tax obligations in Paraguay. Both issuers and recipients must keep copies of the DTEs for this period in a way that guarantees their integrity and accessibility. [imaginesoft.io]
• Format and Storage Requirements: Archiving of e-invoices must be in their original electronic format (XML), since the digital form with the electronic signature and control code is the definitive legal version. While businesses may also store human-readable copies (like PDF representations, i.e., KuDEs), the authenticity and integrity of the records rely on preserving the original signed XML. Paraguay’s e-commerce and digital signature laws (Law 4868/2013 and Law 6822/2021) ensure that properly stored electronic documents have the same legal validity as paper. [lexparaguaya.com]
• Location of Storage: There is no explicit stipulation in the decree or resolutions that archives must be kept within Paraguay, as long as they are readable and available to the tax authority on request. In practice, since the DNIT itself retains an official copy of every approved DTE in its SIFEN database, the tax authority already has access to the data. However, taxpayers still bear the responsibility to maintain their own records, whether on local servers or cloud storage, in a secure manner. The key is that the archiving solution must ensure document authenticity (preserving the digital signatures), integrity (protection against alteration), and readability for the full retention period. Many businesses use local or cloud-based digital archiving systems; others rely on their service providers or the DNIT’s free e-Kuatia portal, which allows storage and retrieval of DTEs. [imaginesoft.io]
• Audit and Access: Archived e-invoices must be available and legible for inspection by the tax authority or auditors upon request. The SIFEN platform facilitates this by providing online consultation services – the DNIT and taxpayers can retrieve any DTE by its control code or other criteria on the official system. Tax auditors can cross-check a taxpayer’s claimed VAT inputs/outputs against the SIFEN database of issued and received DTEs. Thus, proper retention is crucial: failure to produce the electronic records on request could be considered a breach of formal obligations, potentially subject to penalties under the tax code (similar to failing to keep books/records). To mitigate risks, businesses often keep redundant backups (for example, storing DTEs both in the cloud and offline) and ensure that the XML files remain unmodified and accessible (with any proprietary archiving file formats avoided so as not to impede readability).

10. Penalties & Enforcement

Paraguay treats e-invoicing compliance as a formal tax obligation, and non-compliance can trigger sanctions under the tax code and related regulations. Key penalties include:

• Failure to Issue E-Invoices (Continued use of paper when obligated): If a taxpayer does not switch to electronic invoicing by their mandated date (e.g. continues issuing paper invoices), DNIT considers it a serious infraction. Penalties can include fines ranging roughly from 30 to 50 daily minimum wages (jornales) and a temporary closure of the business for 3–5 days in initial instances. The tax authority may issue a formal notice (“intimation”) to comply within 5 business days, but if the violation continues, longer business closures (up to 10 days or more) and higher fines can ensue. These measures are in line with Paraguay’s Tax Law 125/1991, which provides for fines in the range of 10 to 100 minimum daily wages for non-compliance with formal duties like invoicing, and allows business premises to be sealed off for egregious or repeated violations. [evendeha.com.py], [evendeha.com.py] [evendeha.com.py]
• Late or Incorrect E-Reporting: Failure to transmit e-invoices to SIFEN on time (beyond the 72-hour limit) or omitting required information triggers penalties. Specifically, not sending an issued invoice to the tax authority “in time real” (immediately) is punishable by fines of about 15 to 35 days’ minimum wage and the invoices not reported are considered invalid. Likewise, issuing e-invoices with errors or incomplete mandatory data (e.g., missing required fields or incorrect figures) can result in fines of 10 to 30 daily minimum wages per fiscal period. In addition, such faulty documents would be rejected or not counted as valid for VAT deductions until corrected. The enforcement of timely reporting was stepped up in late 2024: after an initial grace period ended, DNIT began imposing small fixed fines (e.g. PYG 100,000 per occurrence) for each late submission of required electronic records. [evendeha.com.py] [rdn.com.py]
• Non-Compliance with Platform Requirements: Using non-authorized systems or failing to integrate properly with SIFEN is also sanctionable. For instance, if a company uses unofficial invoicing software that doesn’t transmit to SIFEN, that’s a breach. Penalties for using non-compliant software or issuing documents outside the approved system include fines of 40 to 60 minimum wages, possible temporary business closure, and invalidation of all invoices issued through that system. In other words, invoices not processed by SIFEN are not recognized (so the business could lose the right to credit or deduct those transactions entirely). [evendeha.com.py]
• Archiving Violations: Maintaining proper records is a fundamental tax obligation. Failure to archive e-invoices for the required period or compromising their integrity could fall under general record-keeping infractions. While specific penalties for e-archiving failures are not enumerated in the e-invoicing decree, under the tax code such issues may attract fines (often in the range of 10 to 30 daily wages for each tax period affected) and, in serious cases, further sanctions. DNIT encourages businesses to keep redundant backups of DTEs to ensure compliance and avoid inadvertent violations. [evendeha.com.py]
• Intentional or Fraudulent Non-Compliance: If a taxpayer deliberately manipulates or evades the e-invoicing system – for example, by issuing parallel unofficial invoices or altering approved DTE data – this would be treated as tax evasion or fraud, not merely a formal lapse. Paraguayan tax law includes severe penalties for fraudulent conduct, potentially including very high fines beyond the standard ranges, or even criminal charges depending on the scale. Additionally, DNIT can invalidate any improperly issued tax documents, leading to denial of VAT credits/deductions and required re-issuance of proper DTEs, impacting both the seller and buyers who relied on the invalid documents. DNIT has highlighted that non-compliance can result in significant business disruptions, as companies may be barred from issuing valid invoices until they rectify their processes, which in turn affects their ability to operate and get paid. [evendeha.com.py], [evendeha.com.py] [flick.network]
• Citation of Legal Bases: The enforcement regime is grounded in existing tax legislation and specific regulations: for example, Article 171 of Law 125/1991 (Paraguay’s main tax code) and Decree 6539/2005 define the range of penalties for invoice-related infractions. The e-invoicing rules (Decree 872/2023 and DNIT resolutions) reiterate that electronic invoices are subject to these general penalty provisions if not properly issued. The DNIT’s emphasis on enforcement has been evident in recent months, with widespread controls and audits to ensure businesses meet their e-invoicing obligations. [evendeha.com.py], [evendeha.com.py]

11. Pre-Filled VAT Returns

• No Pre-Filled VAT Returns (Yet): As of the latest information, Paraguay does not offer pre-filled periodic VAT returns based on e-invoicing data. Taxpayers must continue to file their VAT declarations (Formulario 120) in the normal way, calculating VAT due from their records. However, the comprehensive data collected via SIFEN is expected to facilitate cross-checks and future simplifications. For instance, DNIT can pre-validate the consistency of sales and purchase data (since it has both sides’ DTEs on file) and may move towards providing summary information to taxpayers for verification in the future. But currently, there is no system of DNIT directly populating a taxpayer’s VAT return using SIFEN data, nor any official announcement of such an initiative.
• Future Outlook: Once e-invoicing is fully adopted nationwide, it would be technically feasible for DNIT to pre-complete portions of VAT returns (e.g. total reported sales, total input VAT from supplier invoices). Some countries with mature e-invoicing systems have taken steps toward pre-filled returns or real-time VAT ledgers. Paraguay’s authorities have not implemented this yet. Taxpayers remain responsible for compiling and declaring their VAT figures manually each filing period, using the data from SIFEN (and any paper invoices if applicable) as needed to cross-verify. It is advisable for businesses to reconcile their SIFEN-reported invoices with their VAT returns to ensure consistency and avoid inquiries. If a pre-filled return system is planned in the future, it would likely be communicated by DNIT through official channels or pilot programs; as of now, none have been publicly announced.

12. Impact on SMEs and Startups

• Phased Onboarding & Support: Small and medium-sized enterprises (SMEs) are being gradually onboarded to the e-invoicing regime, giving them more time to prepare. The multi-year phase-in schedule (see Timeline) specifically left SMEs to the later waves (2025–2026), in contrast to large taxpayers who were among the first mandated. This phased approach is explicitly designed to accommodate the capacities of smaller businesses. In addition, the tax authority has provided support tools: notably “e-Kuatia’i”, a free web-based e-invoicing platform for low-volume issuers. This tool spares micro and small businesses from needing to invest in expensive software – they can log in and issue compliant e-invoices through the government’s portal, which handles all the technical aspects (digital signing, XML, transmission, storage) on their behalf. By offering a free solution and a slower rollout, the government has lowered barriers for SMEs.
• Simplified Regimes & Thresholds: SMEs under simplified tax regimes (like the RESIMPLE small business income tax regime) are included in the mandate, but they benefit from simplified DTE types (e.g., the RESIMPLE e-receipt) and likely come at the tail end of the schedule. There is no blanket exemption for SMEs based on revenue thresholds – ultimately even small firms are expected to comply. That said, extremely small traders or individuals with no formal VAT registration (below the RUC threshold) are not directly in scope, since they do not issue standard invoices in the first place. Those micro-entrepreneurs remain outside SIFEN until they formalize. [fonoa.com], [lexparaguaya.com]
• Compliance Costs: For many SMEs and startups, shifting to e-invoicing entails upfront costs – such as updating or acquiring billing software and obtaining digital certificates – but these costs are mitigated by the availability of free or low-cost solutions (like e-Kuatia’i or outsourced providers). Some SMEs opt for third-party e-invoice providers who charge per transaction or a modest subscription, while others stick to the free government platform. According to local advisors, many smaller businesses find that the free system or affordable private solutions keep compliance costs manageable. The government has also provided training materials and guides to help SMEs implement the new system with minimal friction. [evendeha.com.py], [evendeha.com.py]
• Operational Impacts: For SMEs, e-invoicing can bring both burdens and benefits. On one hand, initial implementation requires investing time to learn new digital processes and possibly adjust workflows (e.g. installing software or training staff). On the other hand, in the long run it can streamline record-keeping and reduce manual paperwork. Many businesses find that digital invoices automate calculations and validations, leading to fewer errors in their invoices and VAT filings, which reduces costly corrections and oversight issues down the line. Cash flow might improve for some SMEs since invoices are processed and delivered faster, and official validation is immediate or within days – this can expedite client payments and also ensure that any errors in invoices are caught quickly (in 72 hours or less) rather than surfacing at month-end, thereby avoiding delayed payments or VAT credit rejections. [flick.network]
• Administrative Burden vs Simplification: Initially, SMEs face an increased administrative burden to adapt to e-invoicing – e.g., updating internal procedures and possibly maintaining both electronic and paper systems during the transition. However, after full adoption, administrative processes simplify: no need to obtain paper invoice authorizations (timbrados) or manually deliver physical invoices, and routine tasks like archiving can be automated. The system also promises to reduce the risk of audits and discrepancy penalties for compliant SMEs, since DNIT has direct visibility into transactions, and well-formed e-invoices minimize mistakes. [flick.network]
• Market Impact & Readiness: The e-invoicing mandate is pushing digital transformation among SMEs. Early adopters among SMEs could gain a competitive edge (better internal controls, readiness to do business with larger companies or government that require e-invoices, etc.), whereas laggards may face challenges. There were some concerns from business associations and accountants about SME readiness – for example, in late 2024 professional bodies lobbied DNIT for extended grace periods and system improvements, citing technical issues and challenging timelines for smaller firms. The DNIT responded by engaging with these stakeholders to address technical glitches and by adjusting schedules (as seen with the extension of implementation to 2026). At a broader level, the move to e-invoicing is seen as modernizing Paraguay’s business environment, encouraging SMEs to adopt digital solutions. The government has not announced any direct subsidies or financial assistance specifically for e-invoicing adoption, but the free tools and phased approach serve to ease the transition. In summary, while SMEs have to invest effort to comply, the system is intended to benefit them through simpler compliance in the long run, reduced paperwork, and improved accuracy.

14. Summary

Paraguay’s e-invoicing and e-reporting framework – known as SIFEN – represents a sweeping modernization of the country’s VAT compliance system. In scope are all B2B, B2C, B2G, and cross-border transactions requiring a fiscal document. Taxpayers must shift from paper to digitally signed XML invoices that are cleared by the tax authority (DNIT) in real or near-real time. The mandate is phased over several years: after pilot and voluntary phases, large businesses went first (2022–2023), with medium and small businesses following through 2024–2026 in scheduled groups. By December 2026, all registered businesses will be using e-invoicing, with new companies and government suppliers coming on board even earlier. The e-invoicing system (via e-kuatia/e-kuatia’i) requires standardized electronic invoice formats, comprehensive data fields, and digital security features (e.g. advanced signatures and unique codes). Each invoice is reported to the tax authority’s platform (SIFEN) for validation, ensuring real-time fiscal oversight and data for potential future uses (such as analytics or pre-filled returns, which are not yet implemented). [lexparaguaya.com] [tpa-global.com], [comarch.com] [comarch.com], [comarch.com]

Key obligations for businesses include using only authorized software or the official platform to issue e-invoices (paper documents become invalid after the go-live date), transmitting invoice data within 72 hours of issuance, correcting any errors via approved methods (cancellation events, credit/debit notes), and retaining electronic records for 5 years. Penalties for non-compliance are significant – ranging from fines calculated in “jornales” (daily minimum wages) to temporary business closures for not issuing required e-invoices, with fines also applicable for late reporting or using non-compliant systems. [comarch.com] [rsa.com.py] [tpa-global.com] [evendeha.com.py] [evendeha.com.py], [evendeha.com.py]

For SMEs and startups, the mandate brings initial challenges in technology adoption and training, but the government has mitigated these through a gradual rollout, free e-invoicing tools, and extensive guidance. In the long run, e-invoicing is expected to reduce administrative burdens, improve accuracy, and integrate Paraguay’s businesses into a more modern, transparent tax environment. Critical upcoming dates include the phased deadlines each quarter through 2025–2026, and the enforcement of e-invoicing for all new companies from April 2025 and all government suppliers from January 2026. Businesses are advised to prepare in advance for their respective go-live dates by upgrading their billing systems, obtaining digital certificates, and training staff. The Paraguayan e-invoicing framework is a transformative shift that, while demanding in the short term, aims to foster a more efficient, compliant, and digitally savvy commercial ecosystem in the years ahead.
