1. A Tax Identification Number (TIN) was issued by the Federal Inland Revenue Service (FIRS) before 2026.
2. A Tax ID is the new 13-digit tax number issued by the Nigeria Revenue Service (NRS) from January 2026 under the Nigeria Tax Administration Act, 2025, derived from your NIN (individuals) or RC number (companies).
3. Banks and government agencies now require the new Tax ID only. You can retrieve it instantly via the Nigerian Tax ID Portal using your NIN or RC.

Is Taxpayer ID the Same as TIN?
No, not anymore.
Before 2026, people used “Taxpayer ID,” “TIN,” and “Tax ID” interchangeably.
Now:
1. Taxpayer ID = New NRS Tax ID 2. TIN = Legacy system (old number)
If a bank form says:
1. Taxpayer ID → They mean the new NRS Tax ID 2. Tax ID → Definitely the new one 3. TIN → Clarify, but most institutions now mean the new Tax ID
Why Is a Tax ID Important in Nigeria?
A tax ID is required for:
1. Opening corporate bank accounts 2. Applying for government contracts 3. Paying VAT or Company Income Tax 4. Import/export licensing 5. Tax clearance certificates
Which Law Made the Tax ID Mandatory?
The shift from TIN to Tax ID is driven by Nigeria’s 2025 tax reform laws, especially the Nigeria Tax Administration Act, 2025, which established a unified Tax ID framework. The reform package was signed into law on 26 June 2025 and widely reported as taking effect from 1 January 2026, with Tax ID becoming mandatory for covered taxable persons and for specified banking and regulatory transactions.
Tax ID Requirement for Bank Accounts in Nigeria
Banks no longer require a separately generated TIN.
Instead:
1. Personal accounts: Your NIN is used 2. Company accounts: Your RC number is used
Behind the scenes, the system maps it to your tax ID automatically. If your NIN or RC is valid, your Tax ID exists.
