El Salvador Tax ID Number (TIN) Guide

In El Salvador, a Tax Identification Number (TIN) is essential for individuals, businesses, and legal entities to comply with the country’s tax obligations. The TIN is a unique identifier used for a variety of tax-related processes such as filing taxes, making payments, and engaging in financial transactions. Whether you’re a business owner or an individual taxpayer, having the correct TIN is vital for proper tax compliance and avoiding penalties. 

All the data presented here is 100% verified from official sources, including the El Salvadoran tax authority (Ministerio de Hacienda), to ensure its accuracy. 

1. Tax Identification Number Types 

In El Salvador, the official TIN used for tax purposes is the NIT (Número de Identificación Tributaria). This TIN is used for both individuals and businesses. 

1.1 NIT (Número de Identificación Tributaria) 

  • NIT is the standard tax identification number assigned to individuals and entities (businesses, non-profits, etc.) in El Salvador. 
  • This number is required for anyone engaging in taxable activities, including those filing income tax returns, making VAT payments, or conducting business transactions. 

2. TIN Format and Structure 

The NIT in El Salvador follows a specific format for both individuals and businesses. It consists of 14 digits. 

2.1 NIT Format for Individuals 

  • Format: The NIT for individuals consists of 14 digits (e.g., 1234-567890-1234). 
  • First 4 digits: These represent a unique identifier for the individual. 
  • Next 6 digits: This part corresponds to the personal identification number, which is a unique number assigned to each Salvadoran citizen or resident. 
  • Last 4 digits: These digits are used for validation and checksum purposes, ensuring the number is correctly formatted. 
  • Format: For businesses and legal entities, the NIT format is the same as for individuals (14 digits, e.g., 1234-567890-1234), but it is assigned to the business’s legal registration. 
  • First 4 digits: These correspond to the type of entity (e.g., company, non-profit). 
  • Next 6 digits: This portion contains the unique registration number. 
  • Last 4 digits: The final section consists of the checksum digits for validation. 

The structure for both individual and business TINs is identical in El Salvador, with the key difference being the categorization of the entity type (individual vs. business).

The official tax authority responsible for issuing TINs in El Salvador is the Ministerio de Hacienda (Ministry of Finance).
