Overview of E-Invoicing in Chile (DTE)
E-invoicing in Chile is mandatory for 100% of taxpayers since 2018, regulated by the Servicio de Impuestos Internos (SII) via the Documento Tributario Electrónico (DTE) system.
E-invoicing in Chile is mandatory for 100% of taxpayers since 2018, regulated by the Servicio de Impuestos Internos (SII) via the Documento Tributario Electrónico (DTE) system. Businesses must issue electronic documents for all commercial transactions, subject to the standard IVA (Impuesto al Valor Agregado) rate of 19%. Failure to comply can result in fines ranging from 1 to 3 UTM per document (~CLP 65,000 to 195,000) and the potential suspension of tax certificates.
As one of the global pioneers in electronic fiscal controls, Chile launched its pilot program in 2003. By 2014, Law No. 20.727 established a phased rollout that culminated in April 2018, making electronic issuance the sole legal method for reporting business-to-business (B2B) and business-to-consumer (B2C) sales. Today, the SII operates a sophisticated real-time validation model that ensures tax transparency and reduces evasion.
What is the DTE System?
Understanding Documentos Tributarios Electrónicos
The DTE is a digital file, structured in XML format, that has the same legal validity as a paper invoice. Each DTE must be digitally signed by the issuer using a RUT-linked digital certificate and validated by the SII. The system covers several document types, including:
- Factura Electrónica (Type 33): Standard B2B invoice with IVA breakdown.
- Factura No Afecta o Exenta (Type 34): Invoices for tax-exempt services or goods.
- Nota de Crédito (Type 61): For corrections or cancellations.
- Nota de Débito (Type 56): For increasing original invoice amounts.
- Guía de Despacho (Type 52): Electronic waybills for goods in transit.
- Boleta Electrónica (Type 39): B2C sales receipts (mandatory since 2021).
How Does Chile's E-Invoicing Workflow Work?
Managing invoicing software in Chile requires integration with the SII platform.
Managing invoicing software in Chile requires integration with the SII platform. The workflow typically follows these steps:
- Generation: The taxpayer creates an XML file containing all transaction data, including the CAF (Código de Autorización de Folios) or authorized number range.
- Signing: The document is digitally signed using a private key certificate authorized by the SII.
- Transmission: The file is sent immediately to the SII website via web services.
- Validation: The SII performs structural and fiscal checks. If valid, it issues a receipt of acceptance.
- Exchange: The issuer sends the DTE to the recipient (buyer) via email or a shared repository. The buyer has 8 days to accept or reject the document.
Key Requirements for Compliance in 2026
To stay compliant with Chilean tax laws, businesses must meet several technical and administrative benchmarks. Integrating robust compliance features into your ERP is no longer optional; it is a necessity for business continuity.

Digital Certificates
Every taxpayer must obtain a Digital Signature (Firma Digital) from a certified provider. This signature identifies the representative of the company and ensures the integrity of the XML data sent to the SII.
CAF (Folio Authorization)
Issuers must request "Folios" (sequential numbers) from the SII online portal. These are downloaded as a CAF file and loaded into your accounting tools to be stamped onto each invoice. Without a valid CAF, an invoice is legally void.
The 8-Day Rule
In Chile, once a Factura Electrónica is received, the buyer has exactly 8 days to claim the IVA credit. If they do not explicitly reject the invoice within this window, the SII considers it "acknowledged and accepted," making it an enforceable executive title for debt collection.
Tax Rates and Deadlines
Tax Rates and Deadlines — Standard IVA Rate: 19%.
| Tax Component | Details |
|---|---|
| Standard IVA Rate | 19% |
| Submission Deadline | Real-time (Immediate) |
| F29 Form Deadline | 20th of the following month (for electronic issuers) |
| Record Keeping | 6 years (electronic storage required) |
Penalties for Non-Compliance
The SII is rigorous in enforcing DTE regulations. Non-compliance not only results in financial loss but also disrupts the ability to claim tax credits.

- Failure to Issue DTE: Fines between 50% and 500% of the tax amount, with a minimum of 2 UTM and a maximum of 40 UTM.
- Delayed Reporting: 1 to 3 UTM per document (~CLP 65,000 - 195,000) for failing to transmit documents correctly to the SII.
- Recidivism: Closure of business premises for up to 20 days and suspension of the digital certificate, effectively halting operations.
- Incorrect Data: Errors in the XML structure or tax calculation can lead to audit flags and the rejection of IVA credits for clients, damaging business relationships.
Transitioning to Modern E-Invoicing Solutions
While the SII provides a free basic portal (Sistema de Facturación Gratuito del SII), it is often insufficient for medium-to-large enterprises due to a lack of automation, limited storage, and no integration with inventory or accounting tools.

- Cash Flow Management: Instant visibility into accepted invoices and pending tax credits.
- Audit Readiness: Centralized digital archives meet the 6-year legal storage requirement automatically.
- Scalability: Handle high volumes of Boletas Electrónicas without slowing down POS systems.
