Look, if you’re running a business in Nigeria and you think VAT and Company Income Tax are the same thing, you’re about to get a very expensive education. And trust me, FIRS is not offering any student discounts.
Picture this: You’re at a party, and someone mentions they’re paying “business tax.” Then they start mixing up VAT with Company Income Tax like they’re talking about the same thing. That’s like confusing jollof rice with fried rice — they’re both rice, but try serving the wrong one at a Lagos party and see what happens.
So let’s clear the air once and for all. Because understanding the difference between these two isn’t just smart business — it’s financial survival.
What Exactly is VAT?
VAT (Value Added Tax) is that 7.5% extra you see on almost everything you buy. It’s not your money. It never was your money. You’re just the middleman collecting it for the government.

Think of yourself as a tax collector who doesn’t get paid for the job. You add 7.5% to your product or service price, collect it from your customer, and then hand it over to FIRS. You’re basically doing free work for the government — congratulations, you’re now an unpaid civil servant.
Here’s the thing about VAT: it’s a consumption tax. Your customers are the ones actually paying it, not you. You just happen to be the collection agent. It’s like being the friend who collects money for group contributions — except this time, it’s the government asking, and you can’t say no.
Who Must Register for VAT?
If your business makes ₦25 million or more annually, you’re legally required to register. No negotiations, no “let me think about it.” It’s the law.
But here’s where it gets interesting. Even if you’re not hitting ₦25 million yet, registering voluntarily can be a power move.
Why? Because big companies and serious clients want to work with VAT-registered businesses. It’s like having a VIP pass in the business world.
Now, What About Company Income Tax (CIT)?
Company Income Tax is completely different. This one is actually about YOUR money — the profit your business makes after all is said and done.
CIT is like the government saying, “Congratulations on making money. Now share some of that success with us.” It’s calculated on your company’s profit, not on what your customers pay.
Here’s how the math works:
- Revenue up to ₦25 million: 0% (You’re still in the safe zone)
- ₦25 million to ₦100 million: 20%
- Above ₦100 million: 30% (Welcome to the big leagues)

What is the Key Difference: Timing!
VAT is collected and remitted monthly. Every single month, whether you made sales or not, you need to file your VAT returns by the 21st of the following month.
CIT, on the other hand, is filed annually — within 6 months after your financial year ends. If your company’s year ends in December, your CIT filing is due by June 30th.
The Real-World Impact: A Practical Example
Let’s say you run a catering business and you just catered a corporate event for ₦500,000.
For VAT purposes:
- You charge the client ₦537,500 (₦500,000 + 7.5% VAT)
- That extra ₦37,500 goes straight to FIRS, not your pocket
- You file this in your monthly VAT return
For CIT purposes:
- Your actual revenue from this job is ₦500,000
- After deducting your costs (ingredients, staff, transport, etc.), let’s say your profit is ₦200,000
- This ₦200,000 contributes to your annual profit, which will be taxed at year-end based on your total annual profit
See the difference? VAT is about what flows through your business. CIT is about what stays in your business.
The Consequences of Mixing Them Up
Some business owners make the expensive mistake of thinking they can skip VAT registration because they’re “already paying CIT.” Wrong move. These are completely separate obligations.
Others assume that paying VAT means they don’t owe CIT. Also wrong. You could be paying both, and probably should be if your business is doing well.
The penalty for getting this wrong? Let’s just say FIRS doesn’t offer “my bad” discounts. VAT penalties start at ₦50,000 for the first month you miss filing, then ₦25,000 for every additional month. CIT penalties can be even more brutal.
Pro Tips for Managing Both
For VAT:
- Set up monthly reminders for the 21st deadline
- Keep detailed records of all sales, whether you collected VAT or not
- Even zero-sales months require filing (yes, really)
- Use accounting software that can handle VAT calculations automatically
For CIT:
- Keep accurate profit and loss statements throughout the year
- Don’t wait until filing season to organize your financial records
- Consider quarterly reviews to avoid year-end surprises
- Remember that it’s based on profit, not revenue
The Bottom Line
VAT and Company Income Tax are like two different games with different rules, different deadlines, and different consequences. You can’t play one and ignore the other.
VAT is about being a responsible middleman for the government’s consumption tax. CIT is about sharing your business success with the nation. Both are mandatory if you meet the thresholds. Both will hunt you down if you try to dodge them.
The smart move? Treat them as separate line items in your business operations. Budget for both. File both on time. And maybe, just maybe, you’ll avoid becoming another cautionary tale in Nigerian business circles.
Because at the end of the day, the only thing worse than paying taxes is explaining to FIRS why you didn’t pay them. And trust me, that’s a conversation you want to avoid at all costs.
Remember: Confusion is expensive, but clarity is profitable. Now that you know the difference, you can plan accordingly. Your business — and your bank account — will thank you for it.
