Introduction
A Tax Identification Number (TIN) is an essential identifier for individuals, businesses, and other entities when engaging in tax-related activities. In Chile, the TIN is crucial for ensuring compliance with tax regulations, whether for income tax filings, VAT, or other tax obligations. Having the correct TIN is imperative to avoid delays, penalties, or complications with the Chilean tax authorities.
This guide provides 100% verified information sourced directly from Chile’s official tax authority websites and trusted government resources.
Tax Identification Number Types
In Chile, the Tax Identification Number (TIN) is commonly referred to as the Rol Único Tributario (RUT). It is a unique identifier issued by the Chilean tax authority for both individuals and businesses. Here are the key types of TINs:
- RUT (Rol Único Tributario): This is the primary TIN used for individuals, businesses, and legal entities in Chile.
- RUT for Individuals (RUT de Personas Naturales): Used by natural persons (individuals) who are subject to tax obligations.
- RUT for Businesses (RUT de Personas Jurídicas): Issued to legal entities, including corporations, partnerships, and other business forms.
All the above TIN types fall under the Servicio de Impuestos Internos (SII), the Chilean Internal Revenue Service, which is responsible for managing and issuing RUT numbers.
TIN Format and Structure
The RUT number in Chile follows a specific format for both individuals and businesses:
Format: The RUT consists of a numeric value followed by a check digit (separated by a hyphen).
- Individuals: It is typically 7 digits + 1 letter or digits.
- Businesses: For legal entities, 7 or 8 digits + 1 letter or digits.
The structure of the RUT number is as follows:
- First part (Numeric): Represents the unique identifier for the individual or entity.
- Second part (Check digit): A checksum character that is used to validate the authenticity of the RUT. This is generally a number or the letter ‘K’.
It’s important to note that the RUT format must be followed exactly as prescribed by the Servicio de Impuestos Internos (SII).
Issuing Authority and Registration Process
The Servicio de Impuestos Internos (SII) is the official tax authority responsible for issuing the RUT in Chile. It is essential for individuals and businesses to register with the SII to obtain their TIN.

TIN and VAT Number Connection
In Chile, the RUT also serves as the VAT number for businesses. When a business is registered for VAT, its RUT number automatically functions as the VAT number for tax reporting purposes. The structure of the VAT number follows the same format as the RUT.
Importance of Accurate TIN Validation
Validating the RUT number is critical to ensuring compliance with Chilean tax laws. Businesses and individuals must verify their TIN to avoid the consequences of errors, including:
- Delays in tax filings.
- Penalties for incorrect or missing TINs.
- Complications in business transactions, including invoicing and payments.
Accurate TIN validation ensures that both tax filings and business operations proceed smoothly without legal or financial issues.
Why Accurate TIN Validation Matters
Ensuring the accuracy of your TIN is critical for both businesses and individuals in Chile. An incorrect or unverified TIN—known locally as a Rol Único Tributario (RUT)—can lead to serious complications such as:
- Delays in tax processing
- Rejection of VAT registration or tax exemption claims
- Fines and penalties for non-compliance
- Invalid e-invoicing and reporting submissions
- Onboarding unqualified vendors, suppliers, or clients
