DTE Chile: Mandatory B2B
E-Invoicing Guide
Documentos Tributarios Electrónicos (DTE) are the foundation of Chile’s digital tax framework and the mandatory standard for B2B e-invoicing in the country. Businesses must issue invoices, credit notes, and debit notes in a structured XML format, with digital signature and prior validation by the Servicio de Impuestos Internos (SII) before the document can be delivered to the buyer. This gives the tax authority direct visibility over commercial transactions and makes DTE a central part of day-to-day compliance in Chile.
How DTE supports electronic invoicing compliance in Chile
Key Implementation Dates
Main milestones behind DTE implementation in Chile and the evolution of the country’s mandatory B2B e-invoicing framework
Following Law 20.727, the rollout of mandatory DTE in Chile began progressively, starting with larger taxpayers and extending gradually across different business segments.
From February 2018, the electronic invoicing obligation became broadly applicable across taxpayers in both urban and rural areas. This marked the final stage of Chile’s transition to mandatory DTE for B2B invoicing.
Following the Tax Modernization Act, the rules around the Acuse de Recibo (receipt acknowledgement) became more important for VAT deduction. This reinforced the connection between invoice acceptance, commercial processing, and VAT compliance in Chile’s B2B e-invoicing framework.
DTE Chile Overview
Implementation
Documentos Tributarios Electrónicos (DTE) in Chile operate under a clearance model. The document only becomes valid once it has been validated by the Servicio de Impuestos Internos (SII), which makes prior authorisation a core part of the invoicing process. It applies to B2B invoicing and also plays a role in transactions involving public entities
Tax Authority
SII (Servicio de Impuestos Internos)
Format
XML. All documents must adhere to specific schemas defined by the SII. A critical component is the CAF (Código de Autorización de Folios), a digital file that authorizes the numbering range for each document type
Digital Signature
Mandatory. To ensure authenticity and integrity, every DTE Chile document must be digitally signed using a personal digital certificate issued by an accredited provider.
Archiving
6 years. Taxpayers must archive the XML files of sent and received DTEs for a minimum of six years to meet statutory limitation periods and audit requirements.
Other Chilean regulations
Boleta Electrónica (B2C), Guía de Despacho (Logistics), RCV (VAT Reporting), VAT on Digital Services (Cross-border)

Frequently asked questions
Who is required to use the DTE Chile system?
The DTE Chile system is mandatory for all taxpayers classified under the “First Category” (corporate income tax payers) who carry out commercial activities. Since February 2018, this obligation is universal, covering 100% of businesses regardless of their annual revenue, size, or location (urban or rural). Issuing paper invoices is strictly prohibited, except in specific emergency scenarios authorized by the SII.
What is the "CAF" and why is it essential for DTEs?
The CAF (Código de Autorización de Folios) is a secure digital file provided by the SII that authorizes a specific range of invoice numbers (Folios) for a taxpayer. Unlike other systems where invoice numbering is simply internal, in the DTE Chile framework, businesses must request and download these Folios from the SII. The CAF code must be embedded in the XML of every invoice; without a valid CAF, the document cannot be digitally signed or validated.
Is the "Acuse de Recibo" mandatory for VAT deduction?
Yes. Under current B2B e-invoicing in Chile rules, the “Acuse de Recibo” (Receipt Acknowledgement) is the critical link between the invoice and the fiscal credit. The buyer has a period of 8 days to commercially accept or reject an invoice in the SII registry (RCV). If no action is taken, it is “accepted by default.” Crucially, the buyer cannot utilize the VAT credit associated with that invoice until this acceptance has occurred.
Can DTE Chile processes be automated via ERP?
Yes. While the SII offers a manual portal for small businesses, medium and large enterprises typically bypass this and use “Market Software” solutions integrated with their ERPs. This approach allows for the automated extraction of transaction data, conversion to the required XML format, signing, and transmission to the SII directly from the company’s internal systems, streamlining high-volume DTE Chile operations.
Can foreign companies issue DTEs without a local entity?
Generally, no. To participate in the domestic DTE Chile system (specifically issuing Type 33 invoices), a company must have a Chilean Tax ID (RUT) and be registered with the SII. Foreign entities without a permanent establishment or RUT typically cannot issue local DTEs; instead, they issue international commercial invoices, which follow a different protocol than the domestic standard.
Are there penalties for late submission of DTEs to the SII?
Yes. Failing to send the DTE to the SII immediately after issuance or within the allowed timeframe can result in administrative fines (calculated in UTM – Monthly Tax Units) and interest. Furthermore, repeated non-compliance or irregularities in DTE Chile reporting can lead the SII to restrict the taxpayer’s ability to download new CAFs (Folios), effectively paralyzing their ability to invoice until the situation is resolved.
How mandatory DTE compliance will impact business in Chile
Mandatory Documentos Tributarios Electrónicos (DTE) compliance in Chile affects how businesses issue, receive, and manage electronic tax documents across their day-to-day operations. Companies need to handle invoices, credit notes, and related documents in line with Servicio de Impuestos Internos (SII) requirements, while also supporting digital signature, XML processing, and receipt acknowledgement in a consistent way. As a result, DTE compliance affects not only invoicing, but also how ERP systems support tax control, document traceability, and operational continuity.
At Code10, we enable this transformation by combining SAP standard capabilities with advanced eCompliance integration through SAP Document and Reporting Compliance (SAP DRC) or eCompliance Hub. Our approach leverages standard SAP functionalities wherever possible, while extending them to address local regulatory complexities. This ensures reliable DTE generation, efficient folio management, and secure communication with the SII.
