Honduras Tax ID Number (TIN) Guide

In Honduras, a Tax Identification Number (TIN) is an essential requirement for individuals, businesses, and legal entities to comply with the country’s tax regulations. The TIN is used for a variety of purposes, such as filing taxes, paying fees, and participating in official financial transactions. Without the correct TIN, taxpayers may face delays or penalties when interacting with the tax authorities. 

This guide provides precise, up-to-date information about TINs in Honduras. All data is verified from trusted, official sources such as the Honduran tax authority, ensuring that you receive accurate and authoritative information. 

1. Tax Identification Number Types 

In Honduras, the official TIN is the Número de Identificación Tributaria (NIT). This identifier is required for individuals and entities involved in taxable activities. The NIT is applicable to: 

• Individuals: Used by natural persons to report income and pay taxes. 

• Businesses: Required for all business activities such as VAT (Value Added Tax) filings, payroll taxes, and corporate income tax. 

• Legal Entities: Includes corporations, partnerships, and any legal entity that must report taxes. 

The NIT is the primary TIN used in the country, with no distinction in types for different sectors. It serves as the unique identifier for all tax-related matters. 

2. TIN Format and Structure 

The NIT in Honduras has a specific format for both individuals and businesses. The structure ensures that each TIN is unique and complies with the country’s tax system. 

2.1 RTN Format for Individuals 

• Format: The RTN for individuals consists of 14 digits. 

• The structure of the number is as follows: 

• AA, Department code (geographic region) 

• BB, Municipality code 

• CC, Day of birth (often combined with birth info) 

• YYYY, Year of birth 

• NNNN, Sequential number / Unique identifier 

Example: AABBCCYYYYNNNN 

2.2 RTN Format for Businesses 

• Format: The RTN for businesses also consists of 14 digits, similar to the individual format. 

• The business RTN structure includes: 

• AA, Department code (location of registration) 

• BB, Municipality code 

• CC, Code for legal entity type or registration 

• YYYY, Year of registration 

• NNNN, Sequential number / Unique identifier 

Example: AABBCCYYYYNNNN 

Both formats are used for various tax-related procedures, including VAT registration, filing income tax returns, and paying business-related taxes. 

3. Issuing Authority and Registration Process 

The official tax authority responsible for issuing TINs in Honduras is the Servicio de Administración de Rentas (SAR), which handles the administration and collection of taxes, including the issuance of NITs.

5. TIN and VAT Number Connection

• Format: The NIT for VAT purposes follows the same structure as the general NIT. 

• All businesses operating in Honduras and conducting taxable sales must register for VAT and use their NIT as their VAT identifier.
