El Salvador's Documento Tributario Electrónico (DTE) system is the country's mandatory electronic invoicing framework, established under Legislative Decree No. 487 (approved August 30, 2022). Administered by the DGII (Dirección General de Impuestos Internos), a division of the Ministerio de Hacienda, the system requires every business to generate tax documents in structured JSON format, transmit them to the Ministry of Finance's reception system for validation, and receive a Sello de Recepción (a UUID stamp) before the document carries legal validity.
The DTE framework covers 11 distinct document types, ranging from the Comprobante de Crédito Fiscal used in B2B transactions to the Factura Electrónica for consumer sales, along with specialized documents for exports, credit and debit notes, and other tax events. Each follows the same core lifecycle: generation, transmission, validation, and stamping.
El Salvador uses JSON as the canonical DTE format, unlike XML-based systems in markets such as Mexico, Colombia, Peru, and Ecuador's SRI electronic invoicing system. Finance and IT teams should treat JSON schema validation, digital signature, transmission, and receipt-stamp handling as core implementation requirements.
By January 2026, the Ministry of Finance had received over 1.5 billion DTEs from more than 122,000 registered electronic emitters, according to Infobae's analysis of Ministry of Finance data on El Salvador's DTE adoption.
The rollout is still underway. Businesses have been onboarded in waves based on taxpayer size and classification, with the final mandatory compliance deadline set for May 15, 2026, when micro and small businesses must begin issuing DTEs. Companies operating in El Salvador, trading with Salvadoran suppliers, or processing DTEs in accounts payable should verify their obligations before that date.
All 11 DTE Document Types Explained
El Salvador's DTE system defines 11 distinct document types, each serving a specific transactional purpose. Every document type carries a two-digit code that determines its validation rules, required fields, and tax treatment within the Ministerio de Hacienda's platform.
The following reference table covers all 11 El Salvador DTE document types, their codes, and when each applies.
| Code | Spanish Name | English Equivalent | Purpose / Use Case |
|---|---|---|---|
| 01 | Factura Electronica (FE) | Electronic Invoice | B2C sales to final consumers who will not claim IVA tax credits |
| 03 | Comprobante de Credito Fiscal (CCFE) | Tax Credit Certificate | B2B transactions between NRC-registered taxpayers; enables buyer to claim IVA credits |
| 05 | Nota de Credito (NCE) | Credit Note | Downward adjustments to previously issued documents (returns, discounts, corrections) |
| 06 | Nota de Debito (NDE) | Debit Note | Upward adjustments for additional charges, interest, or price increases on prior documents |
| 07 | Nota de Remision | Remittance Note | Documents the physical movement of goods without an underlying sale (e.g., warehouse transfers) |
| 11 | Comprobante de Retencion (CRE) | Withholding Certificate | Records income tax or IVA withholdings applied by the buyer; see the El Salvador withholding tax invoice guide for CRE rules |
| 14 | Comprobante de Liquidacion (CLE) | Settlement Certificate | Issued by purchasers of agricultural or marine products to document payments to primary producers |
| 15 | Documento Contable de Liquidacion (DCLE) | Accounting Settlement Document | Used for inventory adjustments, consignment settlements, and similar accounting-driven liquidations |
| 43 | Factura de Exportacion (FEXE) | Export Invoice | Issued for export sales, which carry a 0% IVA rate; must include customs and destination data |
| 44 | Factura de Sujeto Excluido (FSEE) | Excluded Subject Invoice | Issued by the buyer when purchasing from a non-VAT-registered party (reversed issuing relationship) |
| 46 | Comprobante de Donacion (CDE) | Donation Certificate | Documents deductible donations to qualifying organizations for income tax purposes |
The Critical CCFE vs. Factura Distinction
For AP departments, the distinction between the Comprobante de Credito Fiscal (CCFE) and the Factura Electronica (FE) is the single most consequential classification decision in El Salvador's e-invoicing system.
The CCFE (code 03) is issued when the buyer holds an active NRC (Numero de Registro de Contribuyente), El Salvador's VAT registration number. This document allows the purchasing company to claim the IVA charged on the transaction as a tax credit against its own IVA liability. To function correctly, the CCFE must contain complete fiscal data for both parties: the NIT (Numero de Identificacion Tributaria), a 14-digit tax identification number, the NRC, and the registered business name of both seller and buyer.
The Factura Electronica (code 01), by contrast, is issued to final consumers. It does not carry the buyer's NRC or full fiscal details, and the IVA included in the price cannot be claimed as a tax credit.
The practical consequence is direct: if a vendor issues a Factura instead of a CCFE for a B2B transaction, the buying company loses its right to deduct the IVA paid. This error cannot be corrected by simply requesting a new document; the original must first be invalidated through the Hacienda's formal process before a replacement CCFE can be issued. AP teams should verify that every B2B purchase from an NRC-registered vendor arrives as a CCFE, not a Factura, before accepting the document.
The Reversed Issuing Relationship of the FSEE
The Factura de Sujeto Excluido (FSEE, code 44) operates differently from every other DTE document type. In a standard transaction, the seller issues the invoice. With the FSEE, the buyer issues the document when purchasing goods or services from a party who is not registered for VAT. This occurs frequently with small vendors, informal suppliers, and individual service providers who fall below the registration threshold. The buyer assumes responsibility for generating the DTE, calculating any applicable withholdings, and transmitting it to the Hacienda, making the FSEE a document type that AP teams must be prepared to originate rather than simply receive. For a field-level breakdown of when this buyer-issued document applies, see our guide to excluded-subject invoice requirements in El Salvador.
DTE Transmission and Validation Workflow
Every DTE must pass through a defined five-step lifecycle before it carries legal weight. Finance and IT teams configuring ERP or billing integrations need to preserve this sequence exactly.
The 5-Step DTE Lifecycle
Step 1: Generation in JSON format. The DTE is created according to DGII-defined JSON schemas. Validation should happen before signature and transmission, because rejected documents do not receive legal status.
Step 2: Digital signature. The generated document is signed using an electronic certificate issued by the DGII. This cryptographic signature authenticates the issuer and ensures the document has not been altered after creation.
Step 3: Transmission to the Ministerio de Hacienda. The signed DTE is sent to the government's validation platform. El Salvador operates a pre-clearance model, meaning the tax authority validates every document before it becomes legally effective. Costa Rica's electronic invoicing and clearance model follows a similar clearance approach, though Costa Rica uses XML rather than JSON.
Step 4: The Sello de Recepcion. Upon successful validation, the DGII assigns a Sello de Recepcion — a UUID that serves as the government's official receipt stamp. A DTE without this stamp has no legal standing: it cannot support tax deductions, prove a transaction, or be presented in an audit.
Step 5: Delivery with representacion grafica. Once stamped, the DTE is delivered to the recipient. Alongside the electronic document, the issuer must provide a representacion grafica — a printable visual version of the DTE that includes a QR code for verification. This ensures recipients who lack electronic processing capabilities can still access and validate the document.
Two Transmission Systems
El Salvador provides two paths for sending DTEs to the Ministerio de Hacienda:
- Sistema de Transmision DTE: API-based integration for businesses with accounting, ERP, or billing software. Systems transmit signed JSON documents and receive the Sello de Recepcion programmatically.
- Sistema de Facturacion DTE: Free government invoicing tool at admin.factura.gob.sv for taxpayers issuing 100 or fewer documents per month, also available as a mobile app. Taxpayers generate, sign, transmit, and receive the Sello de Recepcion inside the government platform.
Rollout Timeline and Compliance Deadlines
Key compliance dates in the DTE rollout:
- August 30, 2022: Legislative Decree 487 was approved, providing the formal legal framework for mandatory electronic invoicing across all taxpayer categories.
- July 2023: Mandatory compliance began for Group 1, consisting of the largest taxpayers.
- October 2023 through April 2024: Groups 2 through 4 were incorporated on a rolling basis, steadily expanding the mandatory base.
- November 15, 2025: Large local and medium taxpayers must comply (extended from an original May 15, 2025 deadline).
- May 15, 2026: Final deadline covering micro businesses, small businesses, and remaining state entities, bringing universal DTE adoption.
By the end of 2024, the system had onboarded 14,462 emitters, representing roughly 13% of registered taxpayers but capturing approximately 89% of all declared sales value.
Personalized Compliance Dates: A Distinctive Approach
El Salvador assigns each company an individual incorporation date rather than relying only on broad taxpayer categories.
Each taxpayer must look up its specific deadline using its NIT on the Ministry of Finance portal. The NIT lookup returns the exact date by which that taxpayer must begin issuing DTEs.
For foreign companies trading with Salvadoran partners, this system adds a layer of due diligence. You cannot assume a supplier or customer is already on the DTE system based on their size alone. Confirming their individual compliance status through the portal or directly with the trading partner is the only reliable method.
How El Salvador's Two-Tier Invalidation System Works
Correcting or cancelling an electronic document after the Ministry of Finance has already validated it requires navigating El Salvador's invalidation event system. Unlike jurisdictions that offer a single, uniform correction window, El Salvador splits its DTE document types into two groups, each with a fundamentally different deadline. Getting this wrong is not a minor procedural issue: once the applicable window closes, the standard event mechanism for invalidation is no longer available.
Group 1: One-Business-Day Deadline
The following document types must be invalidated by 23:59:59 of the next business day after issuance:
- Comprobante de Crédito Fiscal (CCF) — tax credit invoices
- Credit notes
- Debit notes
- Withholding certificates (comprobantes de retención)
- Settlement certificates (liquidaciones)
- Donation certificates (donaciones)
For example, if a CCF is stamped at 2:00 PM on a Tuesday, the issuer has until 11:59:59 PM on Wednesday to submit the invalidation event. If Wednesday is a holiday, the deadline moves to the next business day.
Group 2: 90-Calendar-Day Window
A more generous correction period applies to these three document types:
- Facturas (standard consumer invoices)
- Export invoices (facturas de exportación)
- Sujeto excluido invoices (invoices to excluded taxpayers)
These documents can be invalidated within 90 calendar days of issuance. This extended window was updated in February 2026, replacing a previously shorter period.
Consumers who receive Group 2 documents can also request invalidation when they identify errors in name, NIT, item descriptions, or amounts. This consumer-initiated path follows the same 90-day limit.
The Sello de Recepción as the Baseline Clock
All invalidation deadlines are calculated from the Sello de Recepción timestamp, which is the government's reception stamp applied when the document passes validation. This is a critical distinction: the clock does not start when the document was created in an internal system or when it was transmitted. It starts when the Ministry of Finance stamps it. Any gap between document creation and successful transmission directly compresses the available invalidation window for Group 1 documents.
No Grace Period After Expiration
Once the applicable deadline passes, invalidation through the standard event mechanism is not possible. The public rules do not document any grace period, exception process, or administrative appeal for missed deadlines. For Group 1 documents especially, this means that operational delays in identifying errors can permanently foreclose the correction path.
February 2026 Regulatory Updates
The February 2026 changes extended beyond the Group 2 deadline adjustment. The same update introduced:
- Two new mandatory fields for third-party transactions: identification number and name of the third party must now be included in the DTE when the transaction involves a third-party relationship.
- Updated export invoice requirements, effective February 17, 2026, modifying the data elements required for facturas de exportación.
These changes apply to documents issued on or after their respective effective dates, so document-generation processes should reflect both the new field requirements and the current invalidation windows.
Contingency Procedures and Recipient Data Requirements
Use this operational checklist for the rules that sit outside normal issuance:
- System outages: continue generating DTEs, flag them as contingency documents, store them locally, and batch-transmit them once connectivity returns with the required contingency event message.
- No cancellation while pending: documents generated under contingency cannot be cancelled while awaiting transmission, so treat them as committed transactions until the batch is processed.
- Recipient data threshold: recipient identification is optional on standard invoices unless the transaction equals or exceeds $25,000 USD, the customer requests an invoice for tax deduction purposes, or the data is needed to substantiate deductible expenses.
- Unlawful data collection penalty: demanding identification when none of those conditions apply can trigger a penalty of 30% of the transaction amount, with a floor of two monthly minimum wages.
- Retention: issuers and recipients must retain electronic documents for 10 years from issuance. Recipients claiming deductions from received DTEs should retain their own copies for the same period.
