SUMMARY

Executive Summary

Peru has established one of Latin America’s most comprehensive and technologically advanced e-invoicing and e-reporting frameworks. Mandatory for virtually all registered taxpayers since 2022, the system covers all business transactions (B2B, B2G, B2C, and exports) and a wide array of electronic fiscal documents. The implementation has been phased, leading to a “clearance model” where transactions are validated by the tax authority (SUNAT) in near real-time. Recent developments include the mandatory rollout of the Integrated System of Electronic Records (SIRE) for sales and purchase ledgers, with grace periods extending full enforcement until January 2026. This system leverages e-invoice data to offer pre-filled VAT returns, fundamentally shifting the role of compliance from data compilation to verification. Non-compliance carries severe penalties, including monetary fines and business closure, highlighting the system’s strict enforcement.

Detailed Review

1. Scope of the E-Invoicing & E-Reporting Mandate

Peru’s e-invoicing mandate is exceptionally broad, covering “all business transactions in Peru.” This includes:

  • B2B and B2G invoices (facturas)
  • B2C sales receipts (boletas)
  • Special documents such as credit/debit notes, self-issued purchase invoices, and electronic transport documents (Guías de Remisión Electrónicas).
  • Export invoices are also issued electronically.

The mandate applies to “all domestic transactions whether the customer is a business, consumer, or government entity.” Foreign companies are obligated only if they have a local tax registration (RUC) or fixed establishment. Notably, if a Peruvian business buys from an unregistered supplier (e.g., small farmers or foreign exporters), the buyer may be required to issue a “self-billing document” (“electronic purchase settlement”).

2. Implementation Timeline and Current Status

Peru’s e-invoicing rollout has been a “phased in over many years”:

  • 2010: Voluntary introduction.
  • 2014: Phased mandatory adoption began with the largest taxpayers.
  • 2018: Extended to medium-sized and other designated taxpayers.
  • 2021–2022: Mandate extended to small and micro businesses, achieving “near-100% coverage of all taxpayers by 2022.”
  • Today: Virtually all registered taxpayers must issue and receive invoices electronically, making Peru’s system one of the most extensive in Latin America.
  • B2G: Rolled out concurrently with B2B requirements, meaning suppliers to the public sector must now use e-invoices.

3. Recent Developments (2023-2025) and Grace Periods: SIRE

A major recent initiative is the Integrated System of Electronic Records (SIRE), consolidating electronic Sales Register (RVIE) and Purchase Register (RCE) for VAT purposes.

  • Mandatory Implementation: Initially set for August 2024, it was postponed via Resolución No. 000145-2024/SUNAT to “January 2025.”
  • Grace Periods for Penalties: SUNAT further extended leniency, announcing via Resolución 000003-2025 (Jan 2025) “discretionary non-enforcement” of penalties for SIRE-related non-compliance for the periods January–June 2025. This was later extended, effectively meaning “no SIRE penalties were applied during all of 2025,” pushing true full enforcement to “January 2026.”
  • Meaning of Grace Periods: These periods signify that “no penalties will be applied for non-compliance during the grace period,” offering taxpayers extra time to adapt. However, the transactions still “must be reported,” as it is a delayed enforcement, not an exemption.

4. Future Outlook: Real-time Tax Control

With e-invoicing fully implemented and SIRE coming online, “Peru is moving toward real-time tax control.” The focus is on leveraging the rich data from e-invoices, particularly for streamlining VAT compliance through pre-filled returns.

5. Data Requirements, Format, Transmission, and Clearance

  • Data Requirements: Electronic documents must contain detailed transaction data, including date, type, supplier/buyer identities (name, address, RUC), goods/services details (description, quantity, price, tax), discounts, and total payable.
  • Format: The official format is UBL 2.1 XML, and all documents must be “digitally signed with an authorized digital certificate” to ensure authenticity and integrity.
  • Clearance Model: Peru uses a “clearance model,” where the tax authority (SUNAT) or its delegate validates invoices “before or just as they are issued.”Direct Submission: Large taxpayers can connect directly to SUNAT’s servers (SOL system).
  • Service Providers: More commonly, businesses use accredited Proveedor de Servicios Electrónicos (PSE) and Operador de Servicios Electrónicos (OSE). The PSE formats and signs the XML, which the OSE then validates against over 100 business rules.
  • Validation Receipt: Upon successful validation, an OSE (or SUNAT) issues a “Constancia de Recepción (CDR)” – an acknowledgment of receipt and approval. The e-invoice is only considered valid once the CDR is issued.
  • Asynchronous Validation Risk: While technically possible to send invoices before validation, it’s “risky” because rejection makes the invoice non-tax-valid, requiring re-issuance. Most companies opt for real-time clearance.

6. Types of Documents Covered (CPEs)

The system covers a broad range of “Comprobantes de Pago Electrónicos (CPEs),” including:

  • Invoices (facturas) for B2B/B2G
  • Sales receipts (boletas de venta) for B2C
  • Credit and debit notes
  • Electronic delivery/transport guides (Guías de Remisión Electrónicas – GRE)
  • Invoice cancellation memos (comunicaciones de baja)
  • Withholding and perception receipts.

7. Deadlines for Transmitting Data to the Tax Authority

Strict transmission timelines exist:

  • Electronic invoices (facturas) and associated credit/debit notes: Up to the “third calendar day after the invoice’s issue date.” (Effectively within 4 days of issue date).
  • Electronic public service receipts and certain authorized documents (DAE): Up to “7 calendar days after the day following that date.”
  • Electronic purchase settlement: By the “next calendar day after issuance.”
  • Daily summaries for B2C receipts (boletas): Usually by the “next day” after issuance.

“Prompt reporting is crucial,” and failure to transmit within the allowed window can result in non-compliance. Contingencies (e.g., system outages) allow for temporary paper invoices, but these must be regularized.

8. Penalties for Non-Compliance

Peru imposes “strict penalties” for non-compliance:

  • Failure to issue required electronic documents: Considered a serious infraction, leading to “monetary fines of up to 50% of the tax amount” and potentially “closure of the establishment” (temporary business shutdown).
  • Issuing non-compliant documents: Fines of approximately “~EUR 632” (local currency equivalent) and possible business closure for repeated offenses.
  • Recipient Acknowledgement: While not a direct penalty, if a recipient does not explicitly acknowledge an e-invoice, it is “deemed accepted after 8 calendar days.”

The system’s real-time nature allows SUNAT to quickly identify non-compliance, leading to audits and enforcement actions.

9. Archiving Requirements and Retention Period

Both issuers and recipients must archive e-invoices:

  • Retention Period: A minimum of “5 years” from the first day of the year following the date of issuance.
  • Archiving Format: The “original XML file with digital signature” and the corresponding CDR (validation receipt) must be preserved, not just PDFs.
  • Accessibility: Archived documents “must be accessible to the tax authority upon request.” Issuers must also make invoices available to customers for at least “one year” after issuance.
  • Security: Digital security for archives (integrity and confidentiality) is mandated.

10. Use of E-Invoice Data for Pre-Filled VAT Returns

A significant development is the move toward “pre-filled VAT returns using e-invoice data.”

  • Auto-Generation: Under the SIRE process, SUNAT “auto-generate a draft of the taxpayer’s monthly VAT records” (RVIE and RCE) based on e-invoices issued and received.
  • Taxpayer Review: Taxpayers must review this proposal online and can “Accept, Complement, or Replace” it.
  • Integration with Form 621: Once finalized in SIRE, this information “flows directly into the Form 621 – the monthly IGV (VAT) return” form, which is essentially pre-filled.
  • Shift in Accountant’s Role: The accountant’s job is shifting from compiling data to “auditing SUNAT’s pre-filled data” for accuracy, as taxpayers are warned not to blindly accept inaccurate drafts.

11. References to Regulations and Official Resources

The legal framework is based on various SUNAT resolutions, including:

  • SUNAT Resolución No. 300-2014: Original regulation for the electronic issuance system (SEE).
  • Res. 193-2020/SUNAT: Set the 1-day transmission rule (later extended).
  • Res. 000003-2023/SUNAT: Extended the transmission deadline to 3 days.
  • Res. 000003-2025/SUNAT: Detailed the SIRE grace period.
  • Mandatory e-invoicing resolutions: Res. 155-2017 and subsequent modifications.

SUNAT’s official website provides documentation and the SIRE portal.

Conclusion

“Peru’s e-invoicing and e-reporting framework is comprehensive and technologically advanced.” It mandates electronic transactions for nearly all taxpayers, utilizing a clearance model with specific technical formats (UBL 2.1 XML, digital signatures) and strict reporting deadlines. The ongoing full implementation of SIRE and the introduction of pre-filled VAT returns underscore SUNAT’s drive towards “real-time tax control” and a significantly streamlined, yet demanding, compliance environment. Businesses operating in Peru must ensure robust internal controls and technical integration to meet these obligations, as non-compliance carries severe penalties.

INDEPTH ANALYSIS

Scope of the E-Invoicing/E-Reporting Mandate in Peru:
All business transactions in Peru are covered by the electronic invoicing mandate. This includes B2B and B2G invoices (facturas), B2C sales receipts (boletas), and even special documents like credit/debit notes, self-issued purchase invoices, and electronic transport documents. In other words, e-invoicing is mandatory for all domestic transactions whether the customer is a business, consumer, or government entity. Export invoices are also issued electronically (with a flag indicating an export operation). However, foreign companies without any tax presence in Peru are not directly obligated – only Peruvian companies and foreign companies with a local tax registration (RUC) or fixed establishment must comply. (Notably, even foreign digital platform operators with a tax presence in Peru must issue electronic invoices for their local transactions.) If a business in Peru buys from a supplier who isn’t registered for Peruvian tax (e.g. small farmers or foreign exporters), the buyer may be required to issue a self-billing document (an “electronic purchase settlement”) to document that purchase in the electronic system.

Timeline of Implementation (Past, Current, Future) and Grace Periods: Peru’s e-invoicing rollout has been phased in over many years. Electronic invoicing was first introduced in 2010 as voluntary. A phased mandatory adoption began in 2014 with the largest taxpayers. Subsequent waves in 2018 brought in medium-sized and other designated taxpayers (SUNAT issued resolutions listing taxpayers or sectors required to join by specific dates in 2018). By 2021–2022, the mandate was extended to small and micro businesses, resulting in near-100% coverage of all taxpayers by 2022. The Peruvian tax authority (SUNAT) intentionally used this gradual approach to give businesses time to adapt and to ensure the system’s stability. Today (current), virtually all registered taxpayers in Peru must issue and receive invoices electronically – Peru has one of the most extensive e-invoicing systems in Latin America. [sovos.com] [sovos.com], [sovos.com] [edicomgroup.com], [sovos.com] [ecosio.com] [edicomgroup.com], [ecosio.com]
  • B2G timeline: Electronic invoicing to government entities (B2G) was rolled out along with B2B requirements. Now suppliers to the public sector must use e-invoices, just like B2B, and government bodies are required to accept e-invoices. [sovos.com]
  • Recent developments (2023–2025): SUNAT has been finalizing complementary systems. One major initiative is the Integrated System of Electronic Records (Sistema Integrado de Registros Electrónicos, SIRE), which consolidates the electronic Sales Register (RVIE) and Purchase Register (RCE) for VAT purposes. Initially, SIRE was to become mandatory for additional taxpayers starting August 2024, but this was postponed. SUNAT issued Resolución No. 000145-2024/SUNAT (July 2024) to extend the mandatory SIRE implementation date by ~5 months, making it effective January 2025 instead. This delay was essentially a grace period to give taxpayers more time to prepare for electronic record-keeping. In early 2025, SUNAT further announced it would not immediately enforce penalties for SIRE-related non-compliance for several months. Specifically, via Resolución 000003-2025 (31 Jan 2025), SUNAT applied “discretionary non-enforcement” of penalties for the periods January–June 2025 to facilitate a smoother transition. Taxpayers had until 31 July 2025 to rectify or upload any missing records for that first semester. In mid-2025, authorities extended this leniency even further – effectively no SIRE penalties were applied during all of 2025, pushing the true full enforcement into January 2026 for late adopters. In summary, the electronic ledgers (RVIE/RCE) are now required for nearly all businesses, but 2025 was treated as a grace period to get everyone on board without immediate fines.

  • Future outlook: With e-invoicing fully in place and SIRE coming fully online, Peru is moving toward real-time tax control. The focus is now on using the rich data from e-invoices. Notably, SUNAT is leveraging this data to streamline VAT compliance (see “Pre-Filled VAT Returns” below). Moving forward, businesses can expect SUNAT to integrate these systems even further, possibly introducing new requirements or refinements (e.g. new document types or updated technical standards), but as of end-2025 the major framework is already established.
Data Requirements and Format (What must be reported):
Every electronic invoice or related document in Peru must contain detailed transaction data as specified by SUNAT. The required data includes all the information normally on a tax invoice, for example: the date and time of issue, the type of document, identities of the supplier and buyer (name, address, and RUC tax identification), details of the goods or services supplied (description, quantity, unit of measure, unit prices excluding and including tax), any discounts or additional charges, the applicable tax amount(s) and any exemptions, and the total payable amount. Peru’s electronic invoicing schema requires that all these fields be present in the invoice’s data file to ensure completeness for tax control. [avalara.com] [avalara.com], [avalara.com]
  • Format: The official format for Peruvian e-invoices is UBL 2.1 XML (the OASIS Universal Business Language standard). All Comprobantes de Pago Electrónicos (CPEs) – whether invoices, notes, receipts, etc. – must be generated in this XML format. They also must be digitally signed with an authorized digital certificate to guarantee the document’s authenticity and integrity. A compliant invoice file in Peru is essentially an XML document that meets SUNAT’s UBL schema and includes a valid digital signature. [edicomgroup.com], [avalara.com] [avalara.com], [ecosio.com]
  • Transmission and Clearance Process: Peru uses a clearance model for e-invoicing, meaning the tax authority (or its delegate) plays a role in validating invoices before or just as they are issued. Taxpayers have two main options to send their invoice data to the authorities: [invopop.com]
    • Direct submission to SUNAT: Some large taxpayers connect directly to SUNAT’s servers (using SUNAT’s online system called SOL) and transmit their XML invoices for validation. This requires the company’s own IT system to handle formatting and digital signing, and is generally used by those with significant IT capability. [ecosio.com]
    • Through authorized service providers (PSE/OSE): The more common method is to use an accredited Proveedor de Servicios Electrónicos (PSE) – an electronic service provider – coupled with an Operador de Servicios Electrónicos (OSE). In practice, the PSE takes the company’s invoice data, formats it into the required UBL XML and signs it. The invoice is then sent to an OSE (a SUNAT-authorized operator) which performs an official validation check against over 100 business rules. If the invoice passes all validations, the OSE (or SUNAT itself, in the direct model) issues a “Constancia de Recepción” (CDR) – essentially an acknowledgment of receipt and approval. Only once this CDR is issued is the e-invoice considered fully valid for tax purposes. The OSE/SUNAT returns the CDR (and stamped invoice) to the issuer, who must then deliver the electronic invoice (XML + CDR) to the customer (usually via email or integration). [ecosio.com], [basware.com] [ecosio.com] [ecosio.com], [ecosio.com] [basware.com]
    Important: Peru technically allows invoices to be sent to the buyer before obtaining the SUNAT/OSE validation (i.e., asynchronous validation), but this is risky. If the authority later rejects the invoice (for failing a validation rule), the invoice is not tax-valid and the issuer must correct it and re-issue, which could disrupt business. Therefore, in practice most companies do the clearance in real-time or near-real-time (sending to SUNAT/OSE immediately at issuance) so that the invoice is validated before or at the moment it’s delivered to the customer. [sovos.com]
  • Types of documents covered: The e-invoicing system isn’t just for invoices. SUNAT’s system covers a wide range of electronic fiscal documents (all under the umbrella term CPE). These include standard invoices (facturas) for B2B/B2G, boletas de venta (simplified invoices/receipts for B2C), credit notes and debit notes (which must reference an original invoice), Guías de Remisión Electrónicas (GRE) which are electronic delivery/transport guides required for moving goods, comunicaciones de baja (invoice cancellation memos), withholding and perception receipts for VAT withholding agents, and others as defined by SUNAT. All of these must follow the electronic format and reporting process. By standardizing all transaction types, SUNAT captures both sales and related adjustments or transport documents in its systems. [ecosio.com] [sovos.com]
Deadlines for Transmitting Data to the Tax Authority:
There are strict timelines by when electronic invoices and related data must be sent to SUNAT (or the OSE) after being issued. Initially, SUNAT’s rule was that invoices be reported by the next calendar day after issuance. Compliance with that rule was lower than desired, so SUNAT extended the deadline in 2023. According to Resolution No. 000003-2023/SUNAT, an invoice issuer now has up to the third calendar day after the invoice’s issue date to send the electronic invoice to SUNAT. In practice, this means if you issue an invoice today, you should transmit it as soon as possible, but you have a grace of three additional days (calendar days, not business days) after tomorrow to get it validated. [edicomgroup.com] [edicomgroup.com], [edicomgroup.com]
Different documents have different deadlines, summarized as follows (per SUNAT’s current rules): [edicomgroup.com]
  • Electronic invoices (facturas) and associated credit/debit notes: Must be sent by the issuance date or up to 3 calendar days after the day following issuance. (Effectively up to 3 days after next-day, i.e. within 4 days of the issue date.) [edicomgroup.com]
  • Electronic public service receipts (e.g. utility bills) and certain authorized documents (DAE), and their related notes: Must be sent by the issue date or up to 7 calendar days after the day following that date. (SUNAT provided a longer window for these specific types of documents, recognizing they often involve periodic billing.) [edicomgroup.com]
  • Electronic purchase settlement (self-issued invoice for certain purchases): Must be transmitted by the issue date or at the latest by the next calendar day after issuance. [edicomgroup.com]
  • Daily summaries for B2C receipts: For sales receipts (boletas) issued to consumers, companies typically send a daily summary report rather than individual invoice files for each receipt. The summary of all B2C receipts issued in a day must usually be submitted to SUNAT by the next day. (This rule is part of the electronic invoicing system to capture B2C sales without overloading the system with individual small invoices.) In effect, while an individual “boleta” can be given to a customer immediately, the electronic data for all such receipts is aggregated and sent within about 24 hours in a summary CPE. (Note: This specific point is inferred from the system design – SUNAT’s resolutions allow “individual or daily summary” for receipts, and in practice the daily summary is sent the next day. This ensures even cash sale data is reported almost real-time.) [edicomgroup.com]
In all cases, prompt reporting is crucial. If the data isn’t sent within the allowed window, the invoice may be considered non-compliant. SUNAT actively monitors timely submission, and failing to transmit on time can be a violation. However, the extended 3-day and 7-day windows have improved compliance rates by giving businesses a bit more flexibility. It’s recommended to send all invoices as soon as they are issued (or at day-end for summaries) to avoid any risk. [edicomgroup.com]
If contingencies (system outages, etc.) prevent timely electronic issuance, SUNAT allows use of backup paper invoices, but those must be reported and “regularized” in the system later with proper authorization due to the force majeure event. [sovos.com]
Penalties for Non-Compliance:
Peru imposes strict penalties for not complying with e-invoicing obligations. The consequences can be severe, reflecting how seriously the tax authority takes invoice compliance:
  • Failure to issue invoices or required documents in the mandated electronic format (i.e. not issuing a CPE when you should) is considered a serious infraction. It can result in monetary fines of up to 50% of the tax amount associated with the transaction. In addition, SUNAT can apply closure of the establishment – temporarily shutting down the business premises – for a specified period as a sanction. In practice, SUNAT has the legal authority to close a business for a certain number of days if it finds the business isn’t issuing proper invoices (this is a measure to enforce compliance, used in many Latin countries). [avalara.com] [sovos.com], [sovos.com]
  • Issuing invoices that don’t meet requirements (for example, using an outdated format, not including required information, or using paper when electronic is required) also carries penalties. Sovos notes a specific penalty around ~EUR 632 (in local currency equivalent) for issuing non-compliant documents, and again possibly the closure of the establishment for repeated or serious offenses. In other words, even if you do issue an invoice, if it’s not in the prescribed electronic form or missing required data, you face fines. [sovos.com], [sovos.com]
  • Recipient acknowledgement rules: While not a penalty on the issuer per se, it’s worth noting a compliance rule affecting buyers. Recipients of e-invoices in Peru are supposed to acknowledge receipt. If they do not explicitly acknowledge, the law provides that the invoice is deemed accepted after 8 calendar days. This protects sellers by preventing buyers from indefinitely claiming they didn’t accept an invoice. On the flip side, buyers who intend to reject an invoice (due to errors, etc.) must do so within that timeframe. Failing to comply with this can result in the invoice being binding. [sovos.com]
Overall, non-compliance with Peru’s e-invoicing can draw attention from SUNAT’s enforcement division quickly. The system’s real-time nature means SUNAT knows if you haven’t issued or reported invoices. They can issue reminders or audits, and ultimately levy these fines or closures. Thus, businesses must ensure every sale is properly invoiced electronically and transmitted on time.
Format of E-Invoice and E-Report & Transmission Details: The format for e-invoices (CPEs) is a standard XML based on UBL v2.1 and specific SUNAT requirements. Each invoice’s XML must have a certified digital signature (X.509 certificate) to be valid. Peru mandates the use of e-signatures on all e-documents to assure authenticity and integrity. [edicomgroup.com] [avalara.com] [invopop.com]
For E-Reporting,
the term as used in Peru largely corresponds to the electronic ledger reports (the RVIE and RCE mentioned earlier) and certain summary reports. Under the new SIRE system, taxpayers essentially report their sales and purchase data by ensuring all transactions are recorded via CPEs (for sales) or captured in purchase records. There isn’t a separate “audit file” upload (as in some countries); rather, the continuous invoice reporting throughout the period constitutes the data transmission. That said, businesses still need to review and formally submit their electronic sales/purchase registers to SUNAT (via the SIRE portal) each period. The SIRE platform is online and integrated with SUNAT’s systems – taxpayers log in and confirm that their RVIE (sales) and RCE (purchases) are complete. This replaces the older practice of uploading monthly books (PLE). [summa.org.pe]
If we interpret “E-Reporting” to also encompass any required data reporting beyond invoices: one example is the daily summary for B2C receipts – which is effectively an e-report containing all simplified sales of the day. Another example is the periodic VAT Withholding and VAT Collection reports which designated agents must submit (these are covered by the electronic “comprobantes de retención/percepción” in the CPE list). All these are transmitted electronically through SUNAT’s systems, mostly in XML format as well, using similar channels (SOL portal or PSE/OSE transmission). [sovos.com]
In summary, data transmission to SUNAT is almost entirely electronic and automated via web services. Taxpayers either use SUNAT’s free portal/tools for low volume, or integrate their ERP with a PSE/OSE solution for high volume. As soon as an invoice is generated, its data is electronically reported to the authorities within days (or immediately), satisfying the “e-reporting” aspect. There is no separate paper or offline filing of invoice data – everything funnels through the electronic system.
Grace Periods Meaning:
When Peru provides a grace period (like the SIRE deferral), it typically means no penalties will be applied for non-compliance during the grace period, and deadlines might be extended. For example, the extension of SIRE to January 2025 (and further discretionary non-enforcement to 2025) meant that taxpayers got extra time to adjust their accounting systems without facing fines. In practice, SUNAT uses these grace periods to educate and gradually push taxpayers into compliance. The transactions themselves still eventually must be reported – the grace period is not an exemption but a delayed enforcement. By the end of the grace window, businesses are expected to have all their data caught up in the SIRE. SUNAT’s announcement in August 2025 of no SIRE sanctions until Jan 2026 is explicitly to “not apply sanctions temporarily for certain infractions” while companies finalize their electronic record-keeping. After the grace period, full enforcement (including back penalties if appropriate) resumes. [edicomgroup.com], [sunat.gob.pe]
Archiving Requirements and Retention Period:
Peruvian regulations require that all electronic invoices and related documents be archived and accessible for a set period. Both the issuer and the recipient must keep copies:
  • Retention Period: The general rule is a minimum of 5 years of retention for tax purposes. This five-year period is counted from the first day of the year following the date of issuance (which effectively aligns with the statute of limitations for tax audits in many cases). Some sources even phrase it as “at least five years”; in practice many companies keep them for longer (SUNAT can audit past periods within legal limits). [ecosio.com], [invopop.com] [ecosio.com], [ecosio.com]
  • Archiving Format: The law requires the electronic XML and the corresponding CDR (validation receipt) to be stored. It’s not enough to keep a PDF or printed copy – the original XML file with digital signature must be preserved, because that is the legal invoice. Businesses should also keep the CDR which is proof that SUNAT/OSE approved the invoice. These files must be stored in a secure, legible format (typically on digital media or cloud storage with backups). [ecosio.com], [ecosio.com]
  • Accessibility: During the retention period, the archived e-invoices must be accessible to the tax authority upon request. If SUNAT audits and asks for supporting documents, a company should be able to produce the XML files and CDRs for each transaction in question. Moreover, issuers are required to make the invoices available to their customers for at least one year after issuance for download or printing. This means, for example, if a buyer needs a copy of an invoice, the seller should have a mechanism (web portal or by email) to provide that for up to a year. Beyond that, both parties rely on their archives. [basware.com] [edicomgroup.com]
Peru also mandates digital security for archives – the integrity and confidentiality of archived e-invoices must be ensured. Common practice is to use either certified archiving services or robust internal controls to store these electronic receipts (with some using WORM media or digital vault services). In any case, failure to properly archive could be considered a compliance breach, especially if in an audit the taxpayer cannot produce the invoices.
Use of E-Invoice Data for Pre-Filled VAT Returns:
An important recent development in Peru’s tax administration is the move toward pre-filled VAT returns using e-invoice data. Because SUNAT now receives detailed data for every sale and many purchases (through the electronic system and SIRE), it has the ability to pre-compute what a taxpayer’s VAT declaration should contain. In fact, under the new SIRE process, SUNAT will auto-generate a draft of the taxpayer’s monthly VAT records based on the e-invoices. Specifically, at the start of each month SUNAT’s system compiles all the electronic sales a taxpayer issued (for the sales register) and all the electronic invoices the taxpayer received from suppliers (for the purchase register). Using this, SUNAT provides the taxpayer with a “proposed” record of sales and purchases for the month. The taxpayer must then review that proposal online and either Accept, Complement, or Replace it. [summa.org.pe]
  • If the taxpayer accepts the proposal as is, or adds any missing info and then accepts, the SIRE data is finalized for that period. Once finalized, that information flows directly into the Form 621 – the monthly IGV (VAT) return form. In other words, the VAT return is essentially pre-filled with the totals from the electronic records once you confirm them. This greatly simplifies filing – the taxpayer mainly needs to verify the figures rather than calculate everything from scratch. [summa.org.pe]
  • If the taxpayer finds errors or omissions (for example, maybe some purchase invoices weren’t counted because a supplier sent them late, or there were a few transactions that are not required to be e-invoices), the taxpayer can complement or correct the data in SIRE before submission. They might need to add any non-electronic documents (like certain utility receipts or import documents) that don’t automatically feed into SUNAT’s data. After adjustments, the corrected data is submitted. [summa.org.pe]
This mechanism is essentially Peru’s version of a pre-filled VAT return. It uses the granular e-invoicing data to draft the return, but still relies on the taxpayer to validate it. SUNAT’s push towards this system is to ensure the VAT declarations match the invoices issued/received (“the declaration must mirror exactly the electronic comprobantes”). Indeed, SUNAT’s goal is that the monthly VAT declaration is an exact reflection of the electronic invoices on record. Taxpayers are warned not to blindly accept SUNAT’s draft if they know it’s incomplete – doing so could cause them to overpay or under-report VAT (e.g. missing purchase invoices means losing credit, thereby overpaying VAT). Conversely, if they add data that SUNAT didn’t have and make a mistake, it could trigger an electronic audit flag. This marks a new paradigm: the accountant’s job is shifting from compiling data to auditing SUNAT’s pre-filled data for accuracy. [summa.org.pe], [summa.org.pe] [summa.org.pe]
As of the most recent updates, pre-filled or draft VAT returns are indeed available in Peru for taxpayers using SIRE. It’s an evolving feature, but it represents that Peru’s tax authority is actively using e-invoice data to simplify compliance. (Prior to SIRE, taxpayers had to manually prepare their VAT returns and submit their Libro de Ventas and Libro de Compras each month. Now much of that is automated.)
References to Regulations and Official Resources: The legal basis for Peru’s e-invoicing is established in various SUNAT resolutions and decrees. Key references include SUNAT Resolución No. 300-2014 (which originally regulated the electronic issuance system, SEE), and updated rules like Res. 193-2020/SUNAT (which set the 1-day transmission rule) and Res. 000003-2023/SUNAT (which extended the transmission deadline to 3 days). The mandate that all taxpayers must use e-invoicing came through resolutions in 2017–2018 (e.g., Res. 155-2017 and subsequent modifications listed in the timeline above). SUNAT’s official website provides information on these and hosts a SIRE portal and documentation for taxpayers. For example, SUNAT’s own publication of Res. 000003-2025 (Adjunta) details the grace period for SIRE compliance. Taxpayers and advisors also rely on summary articles and guides from tax solution providers and accounting firms (like the sources cited here) which often link to the official gazette publications of these resolutions.

Conclusion
In conclusion, Peru’s e-invoicing and e-reporting framework is comprehensive and technologically advanced. It covers virtually all transactions (domestic and cross-border sales) and taxpayers, requires standardized electronic formats and near-real-time reporting, and ties directly into monthly tax filings. The implementation has been phased in over roughly a decade, culminating in full adoption by 2022 and the introduction of integrated reporting (SIRE) by 2025. While there have been grace periods and deadline extensions to help companies adjust, compliance is now strictly enforced through automation and significant penalties. Businesses operating in Peru should ensure they understand their obligations under this system – from technical setup (XML formatting, digital certificates) to procedure (timely sending, handling rejections) – and maintain good internal controls, since the tax authority is effectively receiving and checking each invoice in real time. The payoff of this digitization is evident in tools like pre-filled VAT returns, which can simplify compliance for those who follow the rules. All of these points are supported by recent regulations, official SUNAT resolutions, and current analyses by tax compliance experts as linked above.
