This post covers the 4 proven methods to get your TIN. Now, you’ve registered your business with CAC, got your certificate, and now you’re feeling like a proper entrepreneur. Then someone mentions TIN and you’re like “abeg, wetin be TIN again?”
Listen, you’re not alone in this confusion. Most Nigerian business owners treat getting their Tax Identification Number like going to see that uncle who always asks when you’re getting married – something you know you need to do but keep finding excuses to postpone.
Here’s the thing though: your TIN is not one of those things you can do “next month.” It’s literally your business ID card in Nigeria’s tax system, and without it, you’re basically running an invisible business that can’t access serious opportunities.
The good news? Getting your TIN has become much easier than those horror stories your friends told you about spending entire days in government offices. You can actually sort this out from your house while watching Netflix. No jokes!
Why Your Business Desperately Needs a TIN (Like Yesterday)
Before we go into the how-to, let me quickly explain why this number is so important for your business survival in Nigeria.
Your TIN is like your business fingerprint in the Nigerian tax system. Without it, you can’t open a proper business bank account (yes, even those fancy new MFB accounts require it), you can’t bid for government contracts, you can’t get business loans, and when FIRS comes asking questions, you’ll be explaining why you’ve been doing business without proper identification.
Plus, if you ever want to work with serious companies or international clients, they’ll ask for your tax details. Imagine telling a multinational company that wants to pay you millions that you don’t have a TIN. See how that conversation will go?
So yeah, getting your TIN is not optional – it’s your business oxygen.

The Documents You’ll Need (Get These Ready First)
Whether you registered just a business name or you went full boss mode with an LLC, here’s what you’ll need for your TIN application:
For Business Name Registration:
- Your CAC Certificate of Business Name Registration
- Valid ID (National ID, International Passport, or Driver’s License)
- Recent utility bill (not older than 3 months)
- Passport photographs (because Nigerian forms love passport photos)
For Limited Liability Company:
- Certificate of Incorporation from CAC
- Memorandum and Articles of Association
- Form CAC 2 (Return of Allotment of Shares)
- Valid ID of directors and authorized signatories
- Utility bill and passport photographs
Pro tip: Scan everything in high quality before you start. Blurry documents will just waste your time and theirs.
Method 1: The Automatic TIN Through CAC Registration
This is the smoothest route if you’re registering a new business. CAC has finally wised up and now generates your TIN automatically when you register your company. It’s like getting a combo meal – you order business registration and get TIN as a free side.
Here’s how it works: When you complete your business registration through CAC (either online or at their office), they automatically share your details with FIRS, somehow. Your Tax Identification Number is automatically generated and stamped on your Certificate. No extra forms, no extra visits, no extra wahala.
If you haven’t registered your business yet and you’re reading this, definitely go this route. Why stress yourself with multiple processes when you can kill two birds with one stone?
From personal experience, this seem to be more obvious with LLC Registrations than it is with Business Name Registrations.
Method 2: FIRS Self-Registration (The Federal Route)
If you didn’t get automatic TIN or you need to register your business TIN by yourself via the FIRS port as they have actually made their process quite decent. You have two options here:
Online Registration (The Smart Choice)
Head to the FIRS website, create an account, and fill out their TIN registration form. You’ll provide basic information like your name, address, phone number, email, and business type.
The beautiful thing about this method is that you can do it from anywhere – your house, office, or even while stuck in that Ikeja traffic (as a passenger, please). Submit your application online, and you’ll typically get your TIN via email within a few days.
No queues, no “the system is down,” no officer asking you to come back next week.
Physical Registration at FIRS Offices
If you prefer the old-school face-to-face approach, you can visit your nearest FIRS office with all your documents. The staff will help you fill out the forms, and you might even get your TIN the same day if everything aligns properly.
Search using google for “FIRST office near me”.
Method 3: Joint Tax Board (JTB) Registration Through State Revenue Services
The Joint Tax Board coordinates between federal and state tax authorities, and you can get your TIN through participating state revenue services. This is particularly smart if you’re already handling other state-level registrations or if your business primarily operates within one state.
The process is similar to FIRS registration, but you’re dealing with your state revenue service. They collect your information, generate your TIN, and it gets recognized at all government levels. One-stop shopping for your tax needs.
Method 4: State Internal Revenue Service
If you’re doing business within a State, let’s use Lagos for example, LIRS might be your best bet
These guys have invested serious money in making their processes efficient and business-friendly. Lagos being the commercial capital, they understand that entrepreneurs don’t have time for government office drama.
You can register online through their website (www.lirs.gov.ng) or visit any of their offices. What’s impressive is that they often have extended working hours (not guaranteed though), and their online platform actually works when you need it. Plus, their customer service people understand the Lagos business hustle.
For Lagos-based businesses, LIRS registration can sometimes be faster than going through FIRS, especially if you’re already familiar with their other services.
NB: If you’re in Rivers, proceed to RIRS for your TIN.

How to Pick the Right Method for Your Situation
With all these options, you might be wondering which route makes the most sense for you. Here’s the real talk:
- Go with the CAC automatic route if you’re registering a new business. It’s the most efficient and saves you from multiple processes.
- Choose FIRS online registration if you need an individual TIN or have an existing business that didn’t get automatic TIN. It’s fast, convenient, and works from anywhere.
- Pick LIRS if you’re Lagos-based and want efficient service with people who understand the Lagos business environment.
- Go for JTB/State Revenue if your business operates mainly in one state and you want to build relationships with local tax authorities.
Pro Tips to Avoid Common Mistakes
Here are some insider tips that’ll save you time and headaches:
- Get organized first: Have all your documents ready and information memorized before starting any application. Know your business registration number, date of incorporation, and business address by heart.
- Be consistent: Make sure all information matches exactly what’s on your CAC documents. These agencies actually verify details now.
- Don’t multi-apply: Pick one method and see it through. Applying through multiple channels simultaneously creates confusion and might delay everything.
- Follow up: If you don’t hear back within the promised timeframe, call or send emails. Don’t assume everything is fine.
Keep records: Save all confirmation emails, reference numbers, and receipts. You’ll need these for follow-up.
What Happens After You Get Your TIN
Once you have your TIN, you’re officially part of Nigeria’s tax system. You can now open business bank accounts, bid for government contracts, apply for business loans, work with international clients, and most importantly, sleep well knowing you’re compliant with tax laws.
Remember, having a TIN also means you now have tax obligations. FIRS doesn’t play when it comes to filing returns, so make sure you understand what’s expected of you going forward.
The Bottom Line: Stop Postponing This Important Step
Your TIN registration is not something you should keep pushing to “next week.” Your business needs this number to access serious opportunities, and you need the peace of mind that comes with being compliant.
The process is now convenient enough that you can literally sort it out during your lunch break. Choose your preferred method, gather your documents, and get it done.
