Many Nigerians now need a Tax Identification Number for banking, employment, business registration, and government services. To make the process easier, the Federal Inland Revenue Service (FIRS) now allows individuals to retrieve their Tax ID using their National Identification Number (NIN).
You can obtain your Tax ID in Nigeria online by using your NIN through the official FIRS Tax ID portal. The process is free, fully online, and takes only a few minutes if your details are correct.

For individuals, a Tax ID is required for:

With the integration of NIN into government systems, retrieving a Tax ID has become easier.
