Brunei Tax ID Number (TIN) Guide 

Introduction 

The Tax Identification Number (TIN) in Brunei used for taxation and business registration purposes. While individuals do not have a separate TIN, businesses, and entities in Brunei are assigned a registration number that functions as their TIN. This guide provides detailed information about how TINs are assigned, how they are structured, and how businesses and individuals can ensure compliance with Brunei’s tax regulations. All information in this article is 100% verified from official government sources to ensure accuracy and up-to-date guidelines. 

Tax Identification Number Types 

In Brunei, the concept of a separate TIN for individuals does not exist. Instead, the system relies on two main identifiers: 

1. National Registration Identity Card (NRIC): For individuals, the NRIC serves as the primary identifier. The NRIC is an 8-digit number used for administrative and taxation purposes. 

2. Business Registration Numbers: For entities such as sole proprietorships, partnerships, and companies, a registration number issued by the Registry of Companies and Business Names functions as the TIN. There are different formats for different types of businesses: 
   • Sole Proprietorships: 9 characters, formatted as ‘P99999999’. 
   • Private Limited Companies: 10 characters, formatted as ‘RC99999999’. 
   • Foreign Branch Companies: 11 characters, formatted as ‘RFC99999999’. 

These registration numbers are used for tax reporting and other official purposes, ensuring that businesses can comply with tax regulations in Brunei. 

TIN Format and Structure 

National Registration Identity Card (NRIC) Format for Individuals: 

• Format: 8-digit numeric number (e.g., 12345678). 
  • This number is used for tax and other official purposes for Bruneian citizens and residents. 

Business Registration Number Format for Entities: 

• Sole Proprietorships: ‘P99999999’ (9 digits). 
• Private Limited Companies: ‘RC99999999’ (10 digits). 
• Foreign Branch Companies: ‘RFC99999999’ (11 digits). 

The first section of the number typically indicates the type of entity (e.g., ‘P’ for sole proprietorship, ‘RC’ for private companies, and ‘RFC’ for foreign branches). The middle part of the number is a unique identifier, often based on the business registration process. There is no checksum digit in the registration number, but the structure ensures a clear distinction between different entity types. 

Issuing Authority 

The official body responsible for issuing business registration numbers in Brunei is the Registry of Companies and Business Names, under the Ministry of Finance and Economy.

TIN and VAT Number Connection 

Brunei does not have a Value Added Tax (VAT) system. Instead, it implements the Sales Tax and Service Tax (3S Tax), which businesses must comply with. The business registration number also serves as the tax identification number for purposes related to the 3S Tax. 

Why Accurate TIN Validation Matters 

Ensuring the accuracy of your TIN is critical for both businesses and individuals in Brunei. An incorrect or unverified TIN can lead to serious complications such as: 

• Delays in tax processing 

• Rejection of tax exemption claims 

• Fines and penalties for non-compliance
