VAT here is 7.5%
The calculator above works in both directions, and the second one is where most people go wrong.
Adding VAT
Multiply the VAT-exclusive amount by 1.075. ₦1,000 excluding VAT becomes ₦1,075.00.
Removing VAT
Divide by 1.075. You cannot simply subtract 7.5% from a VAT-inclusive price:
| Method | On ₦1,075.00 inclusive | Correct? |
|---|---|---|
| Divide by 1.075 | ₦1,000.00 excl. + ₦75.00 VAT | Yes |
| Subtract 7.5% | ₦994.38 — wrong | No |
The reason: the 7.5% was added to the smaller number, so taking 7.5% off the larger one removes too much. The VAT portion of an inclusive price is 7.5/107.5 of it, not 7.5%.
On a single small invoice the error is trivial. Across a month of business invoicing it is not — and it is the usual reason a supplier's figures and a customer's figures fail to reconcile.
If you are registered for VAT
The VAT you collect is not your money. You hold it on the revenue authority's behalf until your return falls due — and businesses come unstuck on VAT more than on any other tax, almost never through evasion but because collected VAT gets spent as working capital and the bill arrives regardless.
The fix is mechanical rather than a matter of discipline:
- Move the VAT portion to a separate account the day it lands, and never treat it as revenue;
- Show VAT separately on every invoice, so your records reconcile and registered customers can claim it;
- Keep every supplier invoice. Input VAT can generally only be claimed with a valid tax invoice — a missing one is money you simply cannot reclaim;
- Reconcile monthly, not at the deadline. Twelve short sessions beat one impossible reconstruction;
- Diarise your filing dates — late returns attract penalties and interest.
Registration, zero-rating and exemptions
Whether you must register depends on turnover thresholds set locally, and those are revised. Confirm the current threshold with your revenue authority rather than relying on a figure you read somewhere — including here, which is why we do not publish one.
Not everything carries VAT either. Most systems distinguish zero-rated supplies (often basic foodstuffs and exports) from exempt ones — and the difference matters commercially, because zero-rated supplies usually allow input claims while exempt ones do not.
Frequently asked questions
How do I get the VAT out of an inclusive price?
Divide by 1.075. Subtracting 7.5% always understates the excluding price.
Do I have to register?
It depends on your turnover against the local threshold. Confirm with the revenue authority — and understand the administrative load before registering voluntarily.
Is VAT charged on everything?
No — zero-rated and exempt supplies are treated differently, and the distinction affects whether you can reclaim input VAT. Check the current schedules for your goods or services.
Can I claim VAT without an invoice?
Generally not. A valid tax invoice with the required particulars is what supports the claim, which is why invoice discipline is worth more than it feels.
What if I charged the wrong amount?
Correct it promptly and keep the documentation. Errors compound quietly across a filing period and are far cheaper to fix early.
