How to Get Your TIN Number in Nigeria

Nigeria's tax administration transitioned to a new system under the NRS (Nigeria Revenue Service), formerly FIRS, and as of January 2026, there are two identification formats in circulation:

- The legacy 10-digit TIN, issued under the older FIRS system.

- The new 13-digit Tax ID, linked directly to your NIN (National Identification Number), which banks and financial institutions are now increasingly requiring.

Both are valid for tax filing and compliance, but if you're applying fresh in 2026, you'll most likely end up with the newer 13-digit format.

Anyone earning taxable income in Nigeria needs one — this includes salaried employees, freelancers, sole proprietors, registered companies, and even nonprofit organizations, regardless of whether they currently fall below a taxable income threshold. Registering is a legal requirement, not an optional step tied only to how much you earn.

Many Nigerians already have a TIN registered by an employer without realizing it. Before applying fresh, check using either method:

1. Visit taxid.nrs.gov.ng and enter your NIN and date of birth to instantly retrieve your 13-digit Tax ID if one already exists.

2. Visit taxpromax.firs.gov.ng and use the TIN verification feature with your BVN or NIN to check for a legacy 10-digit TIN.

Fastest method — via NRS:

1. Go to taxid.nrs.gov.ng.

2. Enter your NIN and date of birth.

3. Your 13-digit Tax ID is retrieved or generated instantly — this process is free and typically takes under five minutes.

Alternative — via TaxPro-Max:

1. Go to taxpromax.firs.gov.ng and click Sign Up.

2. Choose Individual as your registration type.

3. Enter your full legal name (matching your ID), date of birth, phone number, and email address.

4. Complete identity verification, typically using your NIN or BVN.

5. Submit and wait for confirmation, which usually arrives via email and SMS once your details are verified.

1. Register your business with the Corporate Affairs Commission (CAC) first — you cannot apply for a business TIN without a valid CAC registration.

2. Visit taxpromax.firs.gov.ng and select Non-Individual as the registration type.

3. Provide your CAC registration certificate, memorandum and articles of association (for companies), and identification details for the company's directors.

4. Submit the application online, or visit the nearest NRS/FIRS office in person with physical copies if you prefer that route.

5. You'll receive your TIN via email and SMS once verification is complete.

For individuals:

- A valid government-issued ID (NIN slip, international passport, or driver's license)

- Proof of address (a recent utility bill or bank statement)

For businesses:

- CAC registration certificate

- Memorandum and Articles of Association

- Valid identification for company directors

- Proof of business address

- Registration is completely free. If anyone demands payment to register you or your business for a TIN, that's not a legitimate charge, and it's worth reporting to the relevant tax office.

- Incomplete or mismatched details are the most common cause of delays. Double-check that your name, date of birth, and ID numbers match exactly across all documents before submitting.

- A TIN doesn't mean you'll owe tax immediately. Registration is a compliance requirement for everyone, including those below current taxable income thresholds and registered NGOs.

If you ever need to confirm your own or a business partner's TIN status — for a transaction, a contract, or general due diligence — the TIN Verification System on the NRS/FIRS site allows you to check validity using a name or registration number, which is a useful step before entering into any formal business arrangement.

Keep both your TIN and Tax ID documentation somewhere easily accessible, since you'll reference them repeatedly — for opening bank accounts, filing annual returns, registering for VAT if applicable, and applying for loans or government contracts. It's a small piece of paperwork that ends up touching a surprising number of financial processes down the line.
