How Nigerian VAT Calculation Works
Nigerian VAT (Value Added Tax) is charged at a flat rate of 7.5% on most goods and services under the VAT Act. If you're invoicing a client for ₦500,000 worth of services, the VAT added is ₦37,500 — making the gross total ₦537,500.
Conversely, if you receive an invoice with gross amount of ₦537,500 and need to know the underlying VAT, you reverse-calculate: gross / 1.075 * 0.075 = ₦37,500. This is called ex VAT or removing VAT — essential when reconciling supplier invoices.
Why Nigerian SMEs Need This VAT Calculator
Every time a Nigerian business issues an invoice, files a tax return, or reconciles supplier receipts, they need to calculate VAT correctly. Manual calculation errors lead to:
- ✓ Incorrect invoicing — charging the wrong VAT amount on client invoices creates compliance risk.
- ✓ FIRS penalty exposure — under-remitting VAT triggers penalties and interest from the Federal Inland Revenue Service.
- ✓ Cash flow miscalculations — not knowing the exact net amount before VAT means your pricing is imprecise.
Add VAT vs. Remove VAT
Add VAT is used when you're issuing an invoice and need to show the gross amount to the client. Remove VAT (ex VAT) is used when you have a gross figure (including VAT) and need to find the net amount before tax — common when reconciling supplier invoices or validating contractor quotes.
