How to Find My TIN Number

If you’re looking for how to find your Tax Identification Number (TIN), this article will guide you step-by-step. Whether you’re an individual or business in Nigeria, the process is clearly laid out below. The focus keyword how to find my tin number appears in the title, first paragraph and throughout for clarity.

What is a TIN and why it matters

A Tax Identification Number (TIN) is a unique number issued to you (as an individual) or your business by the tax authority in Nigeria (for example the Federal Inland Revenue Service FIRS) or the relevant State Internal Revenue Service (IRS).

Why it matters:

You need your TIN for filing taxes, doing certain business transactions, opening business bank accounts or registering for VAT, etc.
If you quote an incorrect or inactive TIN you may face compliance issues.
It acts as a permanent identifier once issued, you keep it even if you move states.

Who needs a TIN

In Nigeria, you typically need a TIN if you are:

An individual earning taxable income (employed, self-employed)
A business (company, partnership, sole proprietorship)
Engaged in taxable transactions (VAT, corporate tax, etc)

Even if you think you don’t “need” one now, having your TIN ready simplifies future transactions.

Preparing the information you’ll need

Before you hunt for your TIN, gather the following:

Your unique identification number such as BVN (Bank Verification Number) or NIN (National Identity Number) for individuals.
Date of birth.
For businesses: your registration number (CAC number), business name, etc.
Your email and phone number (in case verification is needed).
Previous records: payslips, tax certificates, any past correspondence from tax authorities—your TIN might already be printed there.

How to find your TIN online (individuals)

Here’s how you can find your TIN if you’re an individual:

Step 1: Visit the official verification/registration portal

Go to the FIRS-run verification portal: TIN Verification – FIRS
Select “Tax Identification Number” as your search criteria.
Also, check your state IRS website (for example, the Federal Capital Territory Internal Revenue Service-FCT-IRS site) which allows you to “Find/Verify TIN” via their e‐service.

Step 2: Enter your details

On the portal, select your search type (TIN, phone number, RC/BN for businesses) and input the search value (your number/details).
For individuals, you may be asked your BVN and date of birth (depending on State IRS) for retrieval.

Step 3: Retrieve the result

If the system recognizes the details, it will display your TIN or confirm you already have one.
If nothing comes up, you might need to register or check if you used another state agency.

Step 4: Save your TIN for future use

Once you have it, keep a digital copy and a hard copy if printed.
Use it on your tax filings, bank account details, etc.

How to find your TIN online (businesses/non-individuals)

Finding a TIN for a business or non-individual entity follows a similar process, with a few extra steps:

Step 1: Visit the business registration portal

Businesses use the same FIRS verification portal:
Or visit the specific State IRS where the business is registered.

Step 2: Input business registration number

On the verification page, select “RC/BN” (Registration Certificate/Business Number) as the criteria.
Enter the registration number, business name, or phone number as required.

Step 3: Check the results

If the business already has a TIN, it will show.
If no record, you may need to apply/ register for one via the business registration portal (for example the Joint Tax Board portal).

Step 4: Print certificate or save official confirmation

Once obtained, download or print the certificate. Many states allow you to download your TIN certificate.
Keep for your filings, VAT registration, business accounts.

What to do if you can’t find your TIN

When you search and nothing shows up, follow these steps:

Double-check your details: Ensure you input the correct BVN/ phone number/ registration number and spelling of your name.
Check across states: If you moved or registered in another state, the TIN might be under a different IRS.
Register anew if needed: If you’ve never got a TIN, you’ll need to apply via the official portals. In some states you can register online.
Visit the tax office: For complex cases or errors, you can physically visit your state’s IRS office with your identification and documents.
Contact support: Use the contact information on the tax authority’s website for guidance (e.g., FCT-IRS contact centre).

Tips for keeping your TIN safe and up to date

Write your TIN in a securely stored file or document.
Use your TIN only via official portals or with verified parties; avoid sharing it indiscriminately.
Whenever you update your details (address, phone, email), ensure your tax record is updated so your TIN remains correctly associated.
When issuing invoices or doing business, always quote the correct TIN – mismatched numbers can lead to delays or penalties.
Periodically verify your TIN online to ensure it’s still active and properly reflected in the system.

Conclusion

Whether you’re an individual or a business, you can find your TIN online via the official portals of the FIRS or your State IRS by entering your relevant identification details. If your TIN does not appear, you may need to register for one or seek assistance. Once retrieved, save it safely and use it properly for all tax-related activities.
