For a long time, many Nigerians earned money without ever needing a Tax Identification Number (TIN). That reality has changed. Today, if you earn an income, whether as a freelancer, business owner, remote worker, or employee, you are expected to have a TIN.
Your TIN is your tax identity. Without it, you will face restrictions when opening bank accounts, registering a business, filing tax returns, accessing government services, or complying with Nigeria’s new tax laws taking effect from January 2026.
Thankfully, here is an all-round guide on how to get a TIN in Nigeria easily and for free.

What Exactly Is a TIN and Why Do You Need It?
A Tax Identification Number (TIN) is a 13-digit unique number issued by the Federal Inland Revenue Service (FIRS) or a State Internal Revenue Service (SIRS). It tracks your tax records, payments, and compliance history over time.
You need a TIN if you:
- Earn a salary or freelance income
- Run a business or side hustle
- Want to open or maintain a corporate bank account
- Register a company with CAC
- Apply for government contracts or financial services
Once issued, your TIN is permanent. It does not expire or need renewal.

How to Get Your TIN in Nigeria Online (Fastest Method)
If you don’t already have a TIN, you can generate one online through the Joint Tax Board (JTB) portal.
- You visit the portal
- Select “Register for Individual TIN,” and
- Enter your BVN, date of birth, and full name exactly as they appear on your bank records.
- The system first checks if a TIN already exists for you. If not, your TIN is generated and sent to your email, usually within 24 to 48 hours.
For businesses, the same portal allows you to apply using your CAC registration number, business name, and company details.
How to Get Your TIN in Nigeria Using the JTB Mobile App
If you prefer mobile access, the Joint Tax Board app (available on Android) lets you register and retrieve your TIN easily.
- You choose whether you’re registering as an individual or a business,
- Enter your BVN, NIN, or CAC details,
- Complete the form, and
- Submit.
- After verification, your TIN is emailed to you.
How to Retrieve Your TIN Using USSD
If you already have a TIN but can’t remember it, dial *829# on your phone.
This USSD service allows you to retrieve your TIN, verify tax records, and locate tax offices. The service costs ₦100 and works across all major networks.
How to Get Your TIN in Nigeria Physically (In Person)
You can also visit the nearest FIRS or State IRS office with:
- Your NIN slip or National ID
- BVN
- Utility bill
- One passport photograph
You’ll fill out a short form, and your TIN may be issued the same day or within a few working days.
Business TIN vs Personal TIN: What You Should Know
If you run a limited liability company (LTD or PLC), your business must have its own TIN, separate from your personal one. But if you operate as a sole proprietor or business name, your personal TIN can serve both personal and business purposes.
Foreign companies doing business in Nigeria are also required to register for a TIN, especially if they earn active income from Nigerian customers.
Important Things Nigerians Often Get Wrong
- Your TIN is free. Anyone charging you money is unnecessary.
- Your BVN and NIN details must match; otherwise, registration will fail.
- Your TIN is not a tax clearance certificate. It only identifies you.
- You can verify your TIN at any time on the FIRS or JTB verification portal.
In Closing
As Nigeria tightens tax compliance ahead of 2026, your TIN is no longer optional; it’s a necessity. Whether you earn locally or globally, personally or through a business, getting your TIN early puts you ahead of the system.
If you earn money in Nigeria, the smartest move you can make right now is to get your TIN, confirm it’s accurate, and keep it safe.
