When preparing an invoice in Nigeria, you need to know whether the agreed price includes Value Added Tax (VAT) or whether VAT must be added separately.
Under the Nigeria Tax Act 2025, the standard VAT rate is 7.5% on taxable supplies, subject to applicable exemptions, zero-rating provisions and other rules.
This guide explains how to calculate VAT on an invoice, what information a VAT invoice should contain, and how VAT and withholding tax can affect the amount your business receives.
Quick Answer: How to Calculate 7.5% VAT
If your price excludes VAT, multiply the price by 7.5% to calculate the VAT. Add the result to the original price to get the invoice total.
Example:
Price before VAT: ₦100,000
VAT at 7.5%: ₦7,500
Total invoice: ₦107,500
If the agreed price already includes VAT, divide the total by 1.075 to find the amount before VAT. Subtract that amount from the total to find the VAT component.
Example:
Total including VAT: ₦107,500
Amount before VAT: ₦100,000
VAT component: ₦7,500

VAT-Exclusive vs. VAT-Inclusive Invoices
Before preparing an invoice, establish whether the agreed price is exclusive of VAT or inclusive of VAT. This affects how you calculate the tax and present the total to your customer.
Method A: Adding VAT to Your Price
Use this method when your quotation or agreement states that VAT will be charged separately.
Suppose you provide a service for ₦500,000 before VAT.
Step 1: Calculate the VAT.
₦500,000 × 7.5% = ₦37,500
Step 2: Add VAT to the service fee.
₦500,000 + ₦37,500 = ₦537,500
The total invoice is ₦537,500, consisting of a service fee of ₦500,000 and VAT of ₦37,500.
Method B: Extracting VAT from an Inclusive Price
Use this method when the agreed amount already includes VAT.
Suppose your customer agrees to pay ₦215,000, inclusive of VAT.
Step 1: Calculate the amount before VAT.
₦215,000 ÷ 1.075 = ₦200,000
Step 2: Calculate the VAT component.
₦215,000 − ₦200,000 = ₦15,000
The total is ₦215,000, consisting of ₦200,000 before VAT and ₦15,000 in VAT.
These examples assume that the supply is subject to the standard 7.5% VAT rate. Different rules may apply to exempt or zero-rated supplies and to businesses covered by applicable small-business provisions.
Sample VAT Invoice in Nigeria
A clear invoice helps your customer understand the transaction and gives both parties a record for accounting and tax purposes.
Here is a simple example of how a service invoice could present the amounts.
SAMPLE VAT INVOICE
Supplier: ABC Business Services Ltd.
Supplier Address: 10 Example Road, Lagos, Nigeria
Supplier Tax ID: [Insert Tax ID]
Invoice Number: INV-2026-001
Date of Supply: 15 October 2026
Customer: XYZ Trading Ltd.
Description of Service: Business consultancy services
Amount Before VAT: ₦500,000
VAT Rate: 7.5%
VAT Amount: ₦37,500
Total Invoice Amount: ₦537,500
Payment Terms: As agreed between the supplier and customer.
This is an illustrative example, not an official government invoice template. Replace the sample details with the correct information for your transaction.
Section 152 of the Nigeria Tax Act 2025 sets out the information required on a VAT invoice, including the supplier's Tax ID, supplier name and address, sequential invoice number, business registration number where applicable, date of supply, purchaser or client name, gross transaction amount, and VAT charged and rate.
A VAT invoice must be issued when the taxable supply takes place, whether or not payment has been received at that time.
Businesses should also keep suitable supporting records, such as descriptions of goods or services, quantities, prices, purchase receipts and payment evidence, to help reconcile their transactions.
Why the Amount You Receive May Be Different from Your Invoice Total
Some Nigerian businesses, particularly service providers working with corporate customers, may receive less cash than the total shown on their invoices because withholding tax (WHT) has been deducted.
VAT and WHT serve different purposes.
VAT is charged on taxable supplies under the applicable rules. WHT is generally a tax deduction made at source on specified payments and may be available as a credit against the recipient's income tax liability.
Consider this example.
A business provides a service for ₦1,000,000 before VAT. Assume the service attracts 7.5% VAT and the payment is subject to a 5% WHT deduction.
Service fee: ₦1,000,000
VAT at 7.5%: ₦75,000
Total invoice: ₦1,075,000
Illustrative WHT deduction at 5% of the service fee: ₦50,000
Cash paid to the supplier: ₦1,025,000
The customer pays ₦1,025,000 to the supplier and deducts ₦50,000 as WHT.
The WHT deduction does not reduce the VAT shown on the invoice. The supplier must account for VAT according to the applicable rules, including any allowable input VAT credits. The supplier should also retain appropriate evidence of the WHT deduction to support the corresponding tax credit.
The 5% WHT rate here is illustrative. The applicable rate depends on the transaction, the parties involved and the relevant rules. Do not assume that every contractor or service provider is subject to the same rate.
Keep Your VAT and Business Records Organized
Preparing an invoice is only one part of managing business finances.
Businesses also need to keep track of sales, purchases, VAT charged, qualifying input VAT paid and payments received. If these records are incomplete or scattered across spreadsheets, notebooks and receipts, reconciling transactions can become difficult.
Good record keeping helps you answer practical questions:
How much did the business invoice customers?
How much VAT was charged on taxable sales?
How much qualifying input VAT was paid on purchases?
Which customers have paid, and which invoices remain outstanding?
Were any withholding tax deductions made?
Can the amounts in the records be reconciled with the relevant tax calculations?

Final Reminder
Calculating VAT correctly involves more than applying a percentage. You need to establish the appropriate VAT treatment, distinguish inclusive prices from exclusive prices, issue invoices with the required information, and maintain records that support your figures.
The standard VAT rate is 7.5%, but not every supply necessarily attracts VAT at that rate. Check the rules that apply to your transaction and business circumstances.
