Electronic Invoicing in Chile, how to comply with the SII and issue DTE automatically

Electronic invoicing system in Chile has been mandatory since 2018 and is part of the tax modernization process driven by the Internal Revenue Service (SII). This model requires all companies to issue their Electronic Tax Documents (DTE) in digital format, with prior validation by the SII. Below, we explain how the system works, which documents must be generated, and how electronic invoicing management can be automated through solutions adapted to the needs of each company.

Status of electronic invoicing in Chile, from voluntary use to mandatory adoption

Chile began its transition to electronic invoicing in 2003, when the Internal Revenue Service (SII) enabled the system on a voluntary basis for taxpayers. Later, with the entry into force of Law No. 20,727 in 2014, mandatory use was established for all companies, applied gradually until full implementation on February 1, 2018. Since then, all tax documentation must be issued electronically, and paper documents are no longer valid.

Latest SII resolutions, most recent changes*

With the aim of continuing to advance digitalization and tax control, the SII has issued new resolutions introducing additional obligations within the electronic invoicing system.

Exempt Resolution No. 99/2025: Formalization of Business Commencement for Digital Platform Service Providers with the SII

Payment service operators, marketplaces, and financial entities are required to verify that sellers or suppliers registered on their platforms have formally registered their activity with the SII. This requirement seeks to ensure that all participants in the digital supply chain are duly registered as active taxpayers.

Exempt Resolution No. 53/2025: obligation to deliver the electronic receipt in in person sales

This resolution, which amends Resolution No. 12/2025, establishes that in all in person transactions the final consumer must be provided with a printed or digital representation of the electronic receipt or payment voucher. This requirement applies regardless of the payment method used and includes digital channels such as email, SMS, QR codes, or messaging apps.

Exempt Resolution No. 154/2025: mandatory registration of delivery notes and new transport types

A Delivery Note Registry is introduced within the SII, requiring the declaration of the type of transport, such as sales, consignment, internal transfer, among others. Delivery notes will be valid only for a single shipment and a single vehicle, and must include the following detailed information:

• Origin and destination address.
• Driver and carrier details.
• Vehicle license plate.
• Full description of the transported goods.

How the electronic invoicing system works in Chile

The electronic invoicing system in Chile is based on the prior validation of Electronic Tax Documents (DTE) by the SII. This means that before being sent to the final customer, documents must first be transmitted to the SII for validation. Only after this validation can they be sent to the recipient in XML format.

The electronic issuer is authorized to both send and receive DTE. Each issued document is transmitted through the invoicing system. Once validated by the SII, it is returned to the issuer and forwarded to the recipient, who has eight days to formally accept or reject it. If no action is taken within this period, the document is considered tacitly accepted.

Electronic invoicing systems for issuing DTE in Chile

There are two options for issuing DTE in Chile:

• Free SII system: Designed for small companies with low issuance volumes. It does not allow integration with other management systems and supports only certain document types.
• Proprietary or market solution: Companies can develop their own software or implement a technological solution such as EDICOM’s. This type of system is designed to issue large volumes of DTE and to integrate with ERP systems and other management platforms.

Types of Electronic Tax Documents (DTE)

The SII establishes different types of DTE that must be issued depending on the transaction. Each document serves a specific purpose and has tax and legal validity for both issuer and recipient. All DTE must include an electronic signature to guarantee integrity and authenticity.

The main mandatory DTE are:

• Electronic invoice: Replaces the traditional paper invoice. It must be authorized by the SII and details the products or services sold, prices, and payment method.
• VAT exempt or nontaxable electronic invoice: Used for tax exempt transactions.
• Purchase invoice: Must be issued if you are authorized as a VAT withholding agent in certain transactions.
• Electronic delivery note: Issued when goods are delivered without an immediate invoice: It verifies and supports the delivery.
• Invoice settlement: Used in consignment transactions, including sales and agreed commissions.
• Credit and debit notes: Used to cancel or modify the amount of an already issued invoice.
• Export invoices and export credit or debit notes: Similar to domestic documents but with additional requirements such as port identification, carrier details, and foreign currency.

How to accept or dispute an electronic invoice with the SII

The recipient has the right to accept or reject an electronic invoice if its content is not correct. Claims may be made for errors in amounts, undelivered products, or conditions not agreed upon, among other reasons. The recipient has seven days from receipt of the invoice to submit a formal claim to the SII.

If no action is taken within this period, the invoice is considered automatically accepted, even if it was not physically received. To help manage these processes, the SII provides a consultation system that allows users to review the status of issued and disputed documents. This tracking is essential to maintain full control of invoices and avoid issues during tax filing.

Invoices not received but reported to the SII, how to manage them

Some suppliers may issue invoices that are valid before the SII but do not reach your internal system. If discrepancies are not detected in time, these invoices are automatically included in the proposed VAT return (Form 29), affecting your accounting records.

To prevent these issues, solutions such as EDICOM’s allow daily reconciliation between documents reported to the SII and those recorded in your ERP. If a discrepancy is detected, the system issues an alert, and if the document is not received within 24 hours, an automatic claim is generated to block the improper inclusion of the DTE.

Electronic delivery note, when and how it must be issued

The electronic delivery note must be issued whenever goods are delivered without an accompanying immediate invoice. This document justifies the delivery of goods and must be numbered and authorized by the SII.

According to regulations, the corresponding invoice must be issued no later than the tenth day of the month following the delivery. However, the maximum allowed date is the last day of the delivery month. The invoice must also include the delivery note number, ensuring full traceability of the commercial transaction.

DTE Archiving, deadlines and formats

Issued and received DTE must be archived for a period of six years and must be kept in the XML format validated by the SII. As an issuer, companies must guarantee storage and access to these documents in the event of an audit. DTE form part of the accounting records and must be available at all times.

The recipient must also archive received electronic documents, unless they are a manual recipient not authorized to operate electronically, in which case the printed version may be retained. The traceability and security of these files are essential to ensure regulatory compliance.

Electronic receipt, technical requirements and current regulations

The electronic receipt is the proof of delivery to the final consumer at the time of purchase. Unlike paper receipts, it shows the breakdown of net price, VAT, and total.

In addition, a Daily Sales Summary must be generated with the previous day’s transactions, electronically signed and sent to the SII. Electronic receipts must:

• Be in XML format
• Include an electronic signature
• Be archived for six years
• Include the Folio Authorization Code (CAF)
• Have a mandatory paper representation for in person sales

If an issued receipt needs to be modified, an electronic credit note must be generated. If the customer purchases a higher value product, a new receipt can be issued for the difference.
