Step-by-Step Guide

TIN Registration

Your Tax Identification Number is now mandatory. Here is how to get one.

What is a TIN?

A Tax Identification Number (TIN) is a unique number assigned to every taxpayer in Nigeria by the Nigeria Revenue Service (NRS). Think of it as your personal tax identity.

Under the Nigeria Tax Administration Act (NTAA) 2025, a TIN is now mandatory for filing tax returns, government contracts, financial services, and official correspondence. It is no longer optional.

Who Needs a TIN?

Everyone who earns income in Nigeria needs a TIN. This includes:

  • •Employees receiving a salary
  • •Freelancers and self-employed individuals
  • •Business owners, sole traders, and companies
  • •Property owners earning rental income
  • •Anyone who needs a bank account or financial service
  • •Anyone applying for government services or official transactions

Even if your income is below the ₦800,000 tax-free threshold, you may still need a TIN for banking and official transactions.
