Saudi Arabia Tax ID Number (TIN) Guide

A Tax Identification Number (TIN) is a unique identifier used by tax authorities to track taxpayers in Saudi Arabia. It is essential for individuals, businesses, and legal entities to have a valid TIN to ensure compliance with tax regulations, report income, and fulfill tax obligations. The TIN serves as a crucial tool for both local and international tax administration. 

This guide provides comprehensive and verified information on Saudi Arabia’s TIN system. All data has been cross-checked with the official Saudi tax authority sources to ensure 100% accuracy and reliability. 

1. Tax Identification Number Types 

In Saudi Arabia, the Tax Identification Number (TIN) is used for both individuals and businesses. The TIN system is unified and applies to all taxpayers, including individuals, corporations, and other legal entities. 

  • Individual TIN: This is assigned to individual taxpayers who are required to pay taxes, such as income tax or Zakat (religious almsgiving). 
  • Business TIN: This is used by companies, corporations, and other entities conducting business activities in Saudi Arabia. The TIN is necessary for businesses to register for VAT, file tax returns, and meet their tax obligations. 

In Saudi Arabia, the TIN is commonly referred to as the “Taxpayer Identification Number” (TIN) for both individuals and businesses. No separate names are used for different types of TINs. 

Key Points

  • Individual TIN: Assigned to individual taxpayers. 
  • Business TIN: Issued to businesses and legal entities. 

All of this information is directly sourced from the official Saudi tax authority, the Zakat, Tax and Customs Authority (ZATCA)

2. TIN Format and Structure 

The structure of the TIN in Saudi Arabia is consistent for both individuals and businesses. It follows a specific format that includes numeric digits. 

  • Format for Individual TIN: The TIN for individuals consists of 12 digits. 
  • Format for Business TIN: The TIN for businesses consists of 10 digits as well. 

TIN Structure

  • First Part: The first section of the TIN may indicate the type of taxpayer (individual or business). 
  • Middle Section: The middle part consists of a unique identification number for each taxpayer. 
  • Last Section: The final part may serve as a checksum or a validation digit, ensuring the TIN’s integrity. 

Both individual and business TINs in Saudi Arabia follow the same basic format, and there are no letters included in the structure. The exact structure and rules are consistent with official guidelines provided by the Zakat, Tax, and Customs Authority (ZATCA). 

3. Issuing Authority and Registration Process 

The Zakat, Tax and Customs Authority (ZATCA) is the official government body responsible for issuing and managing TINs in Saudi Arabia. ZATCA ensures that all taxpayers—whether individuals or businesses—are properly registered and compliant with Saudi tax laws.
