The Federal Inland Revenue Service (Federal Inland Revenue Service) has made it mandatory for individuals and businesses in Nigeria to obtain a Tax Identification Number (TIN) for tax-related activities, including opening bank accounts, registering businesses, and filing tax returns.

The Tax Identification Number is a unique code used to identify individuals and organisations for tax purposes and ensure proper record-keeping within the national tax system.

Who needs a TIN?

Salary earners, business owners, freelancers, and registered companies are all required to have a TIN if they earn taxable income or operate a business in Nigeria.

Banks and government agencies may also request a TIN before processing certain financial or regulatory services.

For salary earners, the process is usually straightforward:

• Visit the nearest FIRS office or state tax office
• Provide valid identification (such as National ID, NIN slip, or international passport)

For business owners, the process may involve additional steps:

FIRS also supports online TIN registration through its official portal, where users can submit details, verify identity, and receive their tax number digitally after approval.
