This guide shows you how to verify your Taxpayer Identification Number (TIN) online in Nigeria — for both individuals and businesses — using official tools from the Federal Inland Revenue Service (FIRS) and the Joint Tax Board (JTB).

Heads up: Always verify on official portals. Never share BVN, NIN, or phone OTPs with third parties claiming to “help”.

What is a TIN and who issues it?

A Taxpayer Identification Number (TIN) is your unique tax ID in Nigeria. Individuals are typically issued a JTB TIN (via State Internal Revenue Services/FCT), while corporate entities are issued FIRS TINs. Both are accepted nationwide for tax purposes.

Taxpayer TypeIssuerTypical Use
IndividualJTB / State IRSPersonal income tax, bank/KYC, government services
Company/BusinessFIRSCompany taxes (CIT, VAT), import/export, contracts, banking

Verify your TIN online (Official FIRS Tool)

Takes about 1–2 minutes.

  1. Open the official FIRS TIN Verification portal: apps.firs.gov.ng/tinverification.
  2. In Select Search Criteria, choose one of:
    • Tax Identification Number (if you already know your TIN)
    • RC/BN (for businesses using CAC Registration/Business Number)
    • Phone Number (the number used during registration)
  3. Enter the value (e.g., your TIN, RC/BN, or phone). For phone searches, you may be prompted for extra details (e.g., date of birth).
  4. Click Search. If valid, you’ll see your name, TIN, tax office, and status.
  5. Take a screenshot or copy down the details for your records.
Tip: FIRS also publishes a help page here: firs.gov.ng/tin-verification.

If you don’t know your TIN (Retrieval options)

Try these in order:

  1. Search by phone on the FIRS portal: apps.firs.gov.ng/tinverification.
  2. Search by RC/BN (businesses) using your CAC registration number.
  3. Check the JTB mobile app (Android) for registration/lookup support: JTB App on Google Play.
  4. If still unsuccessful, visit your nearest FIRS Tax Office or State IRS with a valid ID (NIN/Int’l Passport/Driver’s Licence) and the phone/email used during registration.
Many banks print your TIN on account opening documents or KYC forms — check your files and emails.

Business & Corporate TIN Verification

For companies, you can verify using the CAC RC/BN on the FIRS portal:

  1. Go to FIRS TIN Verification.
  2. Select RC/BN, enter your CAC number exactly as issued (e.g., RC1234567 or BN1234567), then Search.
  3. Confirm the returned business name, TIN, tax office, and status.
If you recently incorporated and can’t find your TIN yet, allow some processing time after CAC registration, or ask your FIRS tax office to confirm linkage.

Quick FAQs

Is my JTB TIN different from FIRS TIN?

They are issued by different authorities but both are valid tax identifiers in Nigeria. Many systems accept either; verify yours via the FIRS tool above.

Can I print a TIN certificate?

Yes — once your record is active, request a copy at your tax office or check emails used during registration for a certificate/acknowledgement.

How long does activation take after registration?

Timelines vary. If your verification fails after a reasonable wait, visit your tax office with your documents for assistance.
