The streets are buzzing. Everyone is talking about January 2026 and how the banks are going to start asking for Tax Identification Numbers before you can touch your account if you earn anything taxable. You might have heard it from friends, online threads, or just scrolling your social media feed, but here is the real breakdown. This isn’t just some government talk that disappears after headlines.
It comes from the Nigeria Tax Administration Act, the law that makes all this mandatory. Starting January 1, 2026, the game changes. If you have income, your bank will want your TIN, no exceptions for taxable Nigerians. That’s you if you earn from work, side hustle, business, or any form of taxable activity.
Banks will be checking, and if you don’t have it, expect friction. But relax, if you already have a TIN, nothing new is needed. It is about linking your money to the tax system properly, making the government’s tracking tighter, and making sure everyone paying taxes can be accounted for.
Why Everyone is Suddenly Talking TIN
Listen, this is not just a random number they want to give you. The government is pushing a reform. Nigeria Tax Administration Act is rolling out with the goal to expand the tax base, get more Nigerians into the system, and improve revenue collection. They are also harmonising identification numbers so your TIN, NIN, and bank records talk to each other.
That means no double registration, no missing links, and less room to dodge taxes. People who are non-taxable, students, and dependents don’t need to panic. They won’t lose access to accounts because they don’t earn taxable income.
The idea is that banks enforce compliance without shutting down innocent accounts. But if you are earning, and you don’t get your TIN sorted, come January 2026, your banking life could become messy.
What You Need to Know Before You Start
First things first, get the basics straight. A TIN is a Tax Identification Number. It is how the Federal Government tracks all taxable activities.
Your bank will ask for it, businesses need it, and even government grants and programs now demand it. You don’t need to re-register if you already have one. If you are new, self-employed, or a first-time earner, now is the time to apply. Banks will start requesting it as part of their compliance checks. This is not optional for taxable Nigerians.
The government has made it clear, anyone who earns and is liable for taxes has to have their TIN linked to bank accounts.
Step One: Check if You Already Have a TIN
Before rushing into applications, check if you already have a TIN. Some of you might have gotten one years ago for business, taxes, or government programs. Pull out old documents, emails, or bank statements. Banks often have TIN records too.
You can also log in to the official tax portal to verify if your number is active. Doing this first prevents duplicate registration which could delay your process and raise flags. Remember, the goal is to ensure you are compliant by January 2026.
Step Two: Gather Your Documents
Now that you know if you need one or not, get your documents ready. For individuals, you will need your National Identification Number, proof of address, and a government-issued ID like your voter’s card or driver’s license.
For businesses, you need your business registration, proof of address, directors’ IDs, and other relevant documents.
The government is pushing for complete records to harmonize TINs with banking systems, so anything missing can slow your registration. Organize everything carefully. Make it smooth for both you and the tax officers.
Step Three: Visit the Official Tax Portal
Nigeria has made online registration possible, so you don’t always have to go to tax offices physically. Go to the official tax portal, create your account, and fill in your details accurately.
Input your full name as per your NIN, enter your date of birth, address, and other personal information. For businesses, ensure the registration matches your corporate documents. Accuracy is critical. Even a small mismatch can cause your TIN to be rejected or delay linking to your bank.
Step Four: Submit Your Application
Once all details are filled, submit your application. You will receive a reference number to track the progress. For individuals, processing is relatively fast, often a few days.
Businesses may take longer depending on verification requirements. Keep track of your submission and don’t ignore any emails or messages from the portal. They may request additional documents to validate your application.
Step Five: Receive and Verify Your TIN
After submission, you will get your TIN certificate. Download and save it digitally. Print a copy too. Verify that all details match your identification and banking information.
Any mismatch can cause problems when linking to banks. This number will now serve as your official identifier for tax matters, bank accounts, and other government programs.
Step Six: Link Your TIN to Your Bank Account
This is the street-smart step that avoids headaches. Go to your bank or use your bank’s online portal to link your TIN to your account. Bring your TIN certificate and valid ID if visiting a branch. Confirm with bank officers that your TIN is fully linked and visible in their system.
Do this for every bank account if you have multiple. From January 2026, banks will start enforcing this strictly, so early action prevents account freezes, holds, or unnecessary back-and-forth.
Step Seven: Stay Compliant and Updated
Having a TIN once is not enough. Keep your details updated. If you move, change name, start a business, or have any significant life events affecting taxation, update your TIN records.
Banks and the government systems are interconnected now, so staying compliant avoids future complications. Track your tax payments, file returns on time, and monitor notifications from tax authorities.

Bottom Line
From January 2026, taxable Nigerians must have a TIN linked to their bank accounts. This is part of the government’s push to modernize the tax system, expand the tax base, and harmonize IDs across platforms.
It’s simple if you act early, organized, and careful. If you already have a TIN, verify and link it to your bank. If you don’t, follow the steps, get registered, submit documents, receive your certificate, and link it before the deadline.
Students, dependents, and non-taxable individuals are safe but knowing your status is key. The streets are talking, the banks are ready, and the government is watching. Take action now, avoid panic later, and stay ahead of the curve.
