How to Get a TIN in Nigeria (2026): NIN, CAC & the New Tax ID

Good news: getting a Tax Identification Number in Nigeria is now simpler and free. Under the 2026 tax reforms your NIN (as an individual) or CAC number (as a business) doubles as your Tax ID — and you can generate it online in minutes. Here is how it works now, and why you will be asked for it more often than you used to be.

Not tax advice. This explains the process in general terms — confirm the current steps on the official NRS portal (the tax office, formerly FIRS).

The big 2026 change

From 1 January 2026, Nigeria simplified tax identification:

• Individuals: your National Identification Number (NIN) now serves as your Tax ID.
• Businesses: your CAC registration number (RC or BN) serves as your corporate Tax ID.

There is also a new 13-digit Tax ID alongside the legacy 10-digit TIN, and banks now require it — they are obliged to collect it for business accounts, so expect to be asked.

The logic of the change is worth understanding: rather than maintaining a separate tax register, the government is keying tax to identity records that already exist. That is why it is fast, and why there is nothing to pay.

Do you even need one?

If you earn income through a job, a trade or any economic activity — yes. If you do not earn (a student or dependant, for example), you generally do not need to obtain one.

Businesses need theirs to open a corporate account, invoice properly, and access funding. In practice, most people discover they need it at the worst moment — at a bank counter, or halfway through a grant application — so generate it before you need it. It takes minutes and costs nothing.

How to get or retrieve your Tax ID

Fastest (individuals):

1. Go to the NRS Tax ID portal — taxid.nrs.gov.ng.
2. Enter your NIN and date of birth.
3. Your Tax ID is generated — free, usually in under five minutes.

Do not have a NIN? That comes first, from the National Identity Management Commission — and it is also what your bank uses under the BVN/NIN linkage rules, see how to link your BVN and NIN.

Companies:

• Enrol in TaxPro Max, the NRS tax-administration system, and validate your TIN if you have not. Your CAC number links to it. Registration is free, and the TIN typically arrives by email within 24–72 hours.

⚠️ Never pay for this

Because the process changed in 2026, a cottage industry of "agents" has appeared offering to get your Tax ID for a fee. It is a free government service that takes five minutes on the official portal. Anyone charging for it is charging you for typing your own NIN into a website.

Two related warnings:

• Use the official portal address and type it yourself. Lookalike sites harvest NINs and dates of birth, which is exactly the data needed to attempt identity fraud against you.
• Your Tax ID is not confidential in the way a password is, but your NIN and BVN are sensitive. Never send them to someone who contacted you first.

If you genuinely want help with company filings, an accredited agent is a legitimate thing to pay for. The Tax ID itself is not.

What you'll need it for

• Opening a corporate bank account — banks now require the 13-digit Tax ID, see how to open a business bank account.
• Filing and paying tax through TaxPro Max — including under the new PAYE bands and on crypto and forex gains.
• Government contracts, grants and funding applications, including the AGSMEIS, MSMEDF and DBN schemes.
• Getting paid by corporate clients, who need it for withholding-tax remittance.

If you have not registered your business yet, do that first — see free CAC registration and business name vs limited company — since your CAC number is your business Tax ID.

Frequently asked questions

Do I still need a separate TIN in 2026? Your NIN (individual) or CAC number (business) now serves as your Tax ID. You generate the linked Tax ID free on the NRS portal, and banks require it for business accounts.

How much does a TIN cost? Nothing. Registration and retrieval through the NRS portal, or TaxPro Max for companies, is free. Never pay an agent for it.

How long does it take? Individuals: usually under five minutes online. Companies: typically 24–72 hours by email after enrolling in TaxPro Max.

Is FIRS still the tax office? It is now the Nigeria Revenue Service (NRS) under the 2025 reform.

I don't have a NIN — what now? Get the NIN first through the National Identity Management Commission; the Tax ID is generated from it.

Do I need a Tax ID if I don't earn anything? Generally no. It is tied to earning income through employment, trade or other economic activity.

Educational information, not tax advice. The tax-ID process and portals are new for 2026 — confirm the current steps on the official NRS channels, and never pay for a free service.
