Do You Need a Tax Identification Number (TIN)? Nigeria's Mandatory 2026 Registration Rules

A Tax Identification Number (TIN) — now called a Tax ID under Nigeria's 2025 tax reform — isn't just paperwork for registered businesses. Since 1 January 2026, registration is mandatory for individuals too, and skipping it carries real costs for both you and whoever pays you.

Who must register, and by when

Every taxable person in Nigeria must register for a Tax ID (TIN) — including individuals earning below the ₦800,000 tax-exempt threshold. Registration became mandatory from 1 January 2026 (NTAA §4); owing ₦0 in tax doesn't exempt you from the registration duty itself.

Earning below ₦800,000? You still must register

The ₦800,000 threshold only decides how much tax you owe — it doesn't decide whether you must register. Falling under NTA's 0% tax band means you owe nothing, not that you're exempt from the registration duty itself. This is the same "exempt from owing, not exempt from the duty" shape TaxLane already applies to the separate annual filing obligation.

The cost of skipping it

A statutory body or company that awards a contract to a business without a registered Tax ID risks an administrative penalty of ₦5,000,000 (NTAA §100(2)) — separate from the unregistered party's own, smaller exposure (₦50,000 for the first month, plus ₦25,000 for each month after, under §100(1)).

Already have a TIN from before the reform?

A Tax ID issued before the 2025 reform (an old FIRS/JTB-issued TIN) remains valid — no fresh registration is required, only a one-time retrieval of the new 13-digit format using your NIN (individuals) or CAC number (businesses) at the official portal.

How to register or retrieve your Tax ID

TaxLane doesn't generate, verify, or register a Tax ID — that has to happen at the official government channel. Visit taxid.nrs.gov.ng and enter your NIN (individuals) or CAC number (businesses) to retrieve or register your Tax ID.
