How to Calculate VAT in Nigeria: Add, Strip & Reverse VAT Explained

Three VAT calculations every Nigerian business needs. How to add 7.5% VAT to a price, strip VAT from a VAT-inclusive amount, and reverse-calculate the VAT component.

VAT in Nigeria is 7.5%. The rate is simple. What trips people up is the arithmetic — particularly the difference between adding VAT to a net price and extracting VAT from a gross price. These are not the same calculation, and confusing them is one of the most common invoicing errors in Nigerian business. A supplier who adds 7.5% to the net price produces one figure. A buyer who tries to extract VAT from the gross price by subtracting 7.5% produces a different figure — and the difference means the invoice is wrong, the VAT return is wrong, and someone is either overpaying or underpaying.

This guide covers the three VAT calculations you will encounter in Nigerian business: adding VAT to a price, stripping VAT from a VAT-inclusive amount, and reversing a VAT figure back to the net price. Each one uses a different formula, and this article walks you through all three with worked examples so you never get them wrong.

Why the Distinction Matters

VAT is a consumption tax — it is charged on the supply of taxable goods and services and ultimately borne by the final consumer. As a VAT-registered business, you are the collection agent: you charge VAT to your customers (output VAT), pay VAT on your business purchases (input VAT), and remit the difference to the NRS each month. Getting the calculation right on every invoice, every receipt, and every VAT return is fundamental to compliance.

The three scenarios you encounter repeatedly are:

• Adding VAT: You know the net price (before VAT) and need to calculate the VAT-inclusive price to show on your invoice.
• Stripping VAT: You have a total amount that already includes VAT and need to separate it into the net price and the VAT component — for your VAT return or your accounting records.
• Reversing VAT: You know the VAT amount and need to work backwards to the net price or the gross price — common when reconciling payments or verifying supplier invoices.

Each scenario uses a different formula. Mixing them up produces incorrect invoices, incorrect VAT returns, and incorrect payments to the NRS — all of which attract penalties.

Calculation 1: Adding VAT to a Net Price

This is the most common calculation. You have agreed a price with your customer for goods or services, and you need to add 7.5% VAT to produce the invoice total.

The Formula

VAT-inclusive price = Net price × 1.075

Or, if you want to see the VAT amount separately:

VAT amount = Net price × 0.075
VAT-inclusive price = Net price + VAT amount

Both methods produce the same result. The first is quicker; the second shows the VAT as a separate line item (which your invoice must do).

Worked Examples

How It Appears on an Invoice

Your invoice should show three elements clearly:

• Net amount (the price of the goods or services before VAT): ₦1,250,000
• VAT at 7.5%: ₦93,750
• Total amount payable: ₦1,343,750

Under the NTA 2025 e-invoicing requirements, VAT invoices for B2B transactions must include the supplier’s name and TIN, the buyer’s name and TIN, the invoice date and number, a description of the goods or services, the net amount, the VAT rate, the VAT amount, and the total. For B2C transactions exceeding ₦50,000, the invoice must be reported to the NRS within 24 hours.

Calculation 2: Stripping VAT From a VAT-Inclusive Price

This is where most errors occur. You receive a payment or see a total price that already includes VAT, and you need to extract the net price and the VAT component. The mistake people make is subtracting 7.5% from the total — which produces the wrong answer.

Why Subtracting 7.5% Is Wrong

If the VAT-inclusive price is ₦107,500 and you subtract 7.5%, you get ₦107,500 × 0.075 = ₦8,062.50. But the actual VAT was ₦7,500 (7.5% of the ₦100,000 net price). The error is ₦562.50 — because 7.5% of ₦107,500 is not the same as 7.5% of ₦100,000. You are taking 7.5% of the wrong base. VAT is 7.5% of the net price, not 7.5% of the gross price.

On small amounts, the error seems trivial. On a ₦50,000,000 contract, the same error produces a ₦348,837 discrepancy — enough to trigger an NRS query and a painful reconciliation.

The Correct Formula

Net price = VAT-inclusive price ÷ 1.075

VAT amount = VAT-inclusive price − Net price

Or equivalently:

VAT amount = VAT-inclusive price × (0.075 ÷ 1.075)

The factor 0.075 ÷ 1.075 = 0.069767… (approximately 6.9767%). This is the effective VAT fraction when extracting from a gross amount. It is not 7.5% — it is lower, because the VAT is calculated on the net price, which is smaller than the gross price.

Worked Examples

The Cross-Check

Always verify: Net price × 0.075 should equal the VAT amount, and Net price + VAT should equal the original VAT-inclusive price.

For the ₦5,000,000 example: ₦4,651,162.79 × 0.075 = ₦348,837.21. ₦4,651,162.79 + ₦348,837.21 = ₦5,000,000.00. Confirmed.

If you had incorrectly subtracted 7.5% from ₦5,000,000, you would have calculated VAT as ₦375,000 and net price as ₦4,625,000. The cross-check fails: ₦4,625,000 × 0.075 = ₦346,875 — not ₦375,000. The numbers do not reconcile because the method was wrong.

Calculation 3: Reversing From a Known VAT Amount

Occasionally you know the VAT amount but need to calculate the net price or the gross price — for example, when reconciling a payment where only the VAT line was provided, or when verifying a supplier’s invoice where the VAT figure does not match the totals.

The Formulas

Net price = VAT amount ÷ 0.075

VAT-inclusive price = Net price + VAT amount

Or in one step:

VAT-inclusive price = VAT amount ÷ 0.075 × 1.075

Worked Examples

When You Need This

The reverse calculation is useful when checking supplier invoices for accuracy. If a supplier’s invoice shows a VAT amount of ₦150,000 and a net price of ₦1,900,000, something is wrong — ₦150,000 ÷ 0.075 = ₦2,000,000, not ₦1,900,000. Either the net price is understated, the VAT is overstated, or the invoice is incorrectly computed. Catching this before payment prevents you from claiming the wrong input VAT on your return.

What Is Subject to VAT and What Is Exempt

Not every transaction attracts VAT. Before applying any of the calculations above, confirm that the goods or services are taxable. The NTA 2025 maintains the following key exemptions:

VAT-Exempt Goods

• Basic food items — unprocessed agricultural produce, staple foods (rice, beans, yams, garri, flour, bread, cereals, cooking oils, fresh fruits and vegetables, fresh and frozen meat and fish)
• Medical and pharmaceutical products
• Baby products (food, clothing, nappies)
• Educational materials (books, newspapers, magazines, educational stationery)
• Agricultural equipment, inputs, and veterinary products
• Plant and machinery for use in export processing zones and free trade zones
• Military equipment and uniforms

VAT-Exempt Services

• Medical services provided by hospitals, clinics, and licensed medical practitioners
• Educational services provided by registered schools, colleges, and universities
• Services rendered under a contract of employment (salaries are not subject to VAT)
• Plays and cultural performances conducted by educational institutions
• Exported services (zero-rated — the supply is taxable but the rate is 0%, allowing the supplier to claim input VAT)

If a transaction involves both taxable and exempt components (a common situation in mixed-supply businesses), only the taxable portion attracts VAT. The exempt portion must be clearly identified and excluded from the VAT calculation.

Input VAT: Claiming Back the VAT You Paid

When you purchase goods or services for your business and pay VAT on those purchases, the VAT you paid is your input VAT. Under the NTA 2025, you can offset input VAT against your output VAT (the VAT you charged to customers) — and only remit the difference to the NRS.

The Monthly Calculation

Net VAT payable = Output VAT − Input VAT

If your output VAT exceeds your input VAT, you remit the difference. If your input VAT exceeds your output VAT (common for capital-intensive businesses or exporters), the excess is carried forward as a credit against future months’ output VAT — or, in the case of exporters, may be refundable.

Worked Example: Monthly VAT Return

NaijaGoods Ltd is a VAT-registered wholesaler. In March 2026:

NaijaGoods remits ₦615,000 to the NRS by 21 April 2026 (the 21st of the month following the transaction month). The ₦637,500 in input VAT has been offset — NaijaGoods only pays the net difference, not the full ₦1,252,500 output VAT.

What Qualifies as Claimable Input VAT

Under the NTA 2025, input VAT is claimable on goods and services (including fixed assets and services) purchased for business purposes. This is a broader scope than the old regime, which restricted input VAT claims primarily to goods. To claim input VAT:

• The purchase must be for business use (not personal consumption)
• You must hold a valid VAT invoice from the supplier showing their TIN, the VAT amount, and the transaction details
• The supplier must be VAT-registered (input VAT from unregistered suppliers cannot be claimed)

If a purchase is partly for business and partly for personal use, only the business portion of the input VAT is claimable. Apply a reasonable apportionment — and document the basis for the split.

Common VAT Calculation Errors

• Subtracting 7.5% to extract VAT from a gross price. The single most common error. VAT is 7.5% of the net price — to extract it from the gross price, divide by 1.075, do not subtract 7.5%. On a ₦10,000,000 invoice, this error overstates the VAT by ₦46,512 and understates the net price by the same amount.
• Charging VAT on exempt supplies. If you sell basic food items, medical services, or educational services, these are exempt from VAT. Charging 7.5% on an exempt supply creates an incorrect invoice, an overstated output VAT liability, and a confused customer. Verify whether each supply is taxable before applying VAT.
• Not claiming input VAT on services. Under the NTA 2025, input VAT on services (rent, consulting, logistics, IT, legal) is now claimable — not just VAT on goods. Many businesses still fail to claim service-related input VAT because their systems or their accountants have not updated for the expanded scope. Every unclaimed input VAT is money left on the table.
• Claiming input VAT without a valid invoice. You need a VAT invoice from a VAT-registered supplier to claim input VAT. A receipt without a TIN, without a VAT amount, or from an unregistered supplier does not qualify. If the NRS disallows the input claim during an audit, you owe the full output VAT without offset.
• Mixing VAT-inclusive and VAT-exclusive prices on the same invoice. Some invoices show some line items at net prices and others at gross prices, then apply VAT inconsistently. Every line item should be at the net price, with VAT added as a single line at the bottom — or each line item should show the VAT separately. Mixing the two creates reconciliation errors on both the seller’s and the buyer’s VAT returns.
• Applying VAT to WHT-adjusted amounts. VAT and WHT are separate obligations calculated on separate bases. VAT is charged on the full net price of the supply. WHT is deducted by the buyer from the payment to the supplier. Do not reduce the VAT base by the WHT amount — VAT is computed on the full net price before any WHT deduction.

VAT and WHT: How They Interact on a Single Invoice

This causes more confusion than any other aspect of Nigerian invoicing. When a VAT-registered supplier issues an invoice to a company that is obligated to deduct WHT, both taxes apply to the same transaction — but on different bases and in different directions.

The Sequence

1. The supplier invoices the net price plus VAT
2. The buyer deducts WHT from the net price (not from the VAT-inclusive amount)
3. The buyer pays the supplier: net price minus WHT plus VAT
4. The buyer remits the WHT to the NRS and issues a WHT credit note to the supplier
5. The supplier reports the full output VAT on their VAT return and offsets the WHT against their income tax liability

Worked Example: Invoice With Both VAT and WHT

Apex Consulting Ltd (VAT-registered) provides management consulting services to BrightStar Industries Ltd. The consulting fee is ₦4,000,000. WHT on consultancy paid to a company is 10%.

Key points:

• VAT (₦300,000) is calculated on the net fee (₦4,000,000), not on the net fee minus WHT
• WHT (₦400,000) is calculated on the net fee (₦4,000,000), not on the VAT-inclusive amount
• The buyer pays ₦3,900,000 to the supplier (₦4,000,000 − ₦400,000 + ₦300,000)
• The buyer remits ₦400,000 WHT to the NRS and issues a credit note to Apex
• Apex declares ₦300,000 as output VAT on their monthly return
• Apex claims the ₦400,000 WHT as a credit against their CIT or PIT liability at year-end

Neither VAT nor WHT is calculated on the other. They are parallel deductions from the same net price — VAT goes from the buyer to the supplier (who remits it to the NRS), and WHT goes from the buyer directly to the NRS on behalf of the supplier.

Filing Your Monthly VAT Return

VAT returns are filed monthly with the NRS through the NRS Self-Service Portal. The deadline is the 21st of the month following the transaction month. January VAT is due by 21 February. February VAT is due by 21 March.

The return requires:

• Total output VAT charged during the month
• Total input VAT paid during the month (with valid VAT invoices)
• Net VAT payable (output minus input) or net VAT credit (if input exceeds output)
• Payment of the net VAT payable

Late filing attracts ₦100,000 for the first month and ₦50,000 for each subsequent month under NTAA Section 101. Late payment of the VAT liability attracts the principal amount plus 10% per annum plus interest at the CBN Monetary Policy Rate.

The ₦50,000,000 VAT Filing Exemption

Under the NTAA 2025, businesses with annual turnover of ₦50,000,000 or below are not required to file VAT returns — though they may register voluntarily if they wish to charge VAT and claim input credits. If your turnover is below this threshold, you are effectively exempt from the VAT filing obligation. However, you still pay VAT on your purchases — you simply do not charge it on your sales or file monthly returns.

Quick Reference: VAT Rates in Nigeria

The distinction between exempt and zero-rated matters for input VAT. If you make exempt supplies, you cannot claim input VAT on purchases related to those supplies. If you make zero-rated supplies (exports), you can claim input VAT — and may be entitled to a refund if your input VAT consistently exceeds your output VAT.

Final Thoughts

VAT arithmetic in Nigeria comes down to three operations: multiply by 1.075 to add VAT, divide by 1.075 to strip VAT, and divide by 0.075 to reverse from a VAT amount. The rate is 7.5%, but the extraction factor is approximately 6.977% — and the difference between the two is where most invoicing errors live. Getting this right on every invoice protects your VAT return, your input claims, and your relationship with the NRS.

The broader compliance picture — registering for VAT, filing monthly by the 21st, claiming input VAT on goods and services, handling VAT alongside WHT on the same invoice, and knowing which supplies are exempt — is equally important. A correct calculation on an exempt supply is still wrong. A correct invoice without a monthly return filing is still non-compliant.

FAQs About Calculating VAT in Nigeria

What is the VAT rate in Nigeria?

7.5% on the supply of taxable goods and services under the NTA 2025. This rate has been in effect since February 2020 (increased from the previous 5%). Exempt supplies (basic food, medical services, educational services) attract no VAT. Exported goods and services are zero-rated (0% VAT, with input VAT still claimable).

How do I add VAT to a price?

Multiply the net price by 1.075. A net price of ₦500,000 becomes ₦537,500 inclusive of VAT. The VAT amount is ₦500,000 × 0.075 = ₦37,500. Your invoice should show the net price, the VAT amount, and the total separately.

How do I extract VAT from a VAT-inclusive price?

Divide the VAT-inclusive price by 1.075 to get the net price. Do not subtract 7.5% — that produces the wrong answer. For ₦1,000,000 inclusive of VAT: ₦1,000,000 ÷ 1.075 = ₦930,232.56 net, with ₦69,767.44 in VAT. Cross-check: ₦930,232.56 × 0.075 = ₦69,767.44. Confirmed.

Why can I not just subtract 7.5% to find the VAT?

Because VAT is 7.5% of the net price, not 7.5% of the gross price. The gross price already includes the VAT, so taking 7.5% of the gross overstates the VAT. On ₦10,000,000, subtracting 7.5% gives ₦750,000 — but the correct VAT is ₦697,674.42 (₦10,000,000 ÷ 1.075 = ₦9,302,325.58 net; ₦9,302,325.58 × 0.075 = ₦697,674.42). The ₦52,325.58 difference is real money — and on your VAT return, it is an error.

Is WHT deducted before or after VAT is calculated?

Neither — they are calculated independently on the same net price. VAT at 7.5% is added to the net price. WHT is deducted from the net price by the buyer. The buyer pays the supplier the net price minus WHT plus VAT. VAT is never calculated on a WHT-adjusted amount, and WHT is never calculated on a VAT-inclusive amount.

Do I need to file VAT returns if my turnover is below ₦50 million?

No. Under the NTAA 2025, businesses with annual turnover of ₦50,000,000 or below are not required to file VAT returns. You may register voluntarily if you want to charge VAT and claim input credits, but you are not obligated to. You still pay VAT on your own purchases — you simply do not collect or remit it on your sales.

Can I claim input VAT on services under the NTA 2025?

Yes. The NTA 2025 expanded the scope of input VAT to include services and fixed assets — not just goods. VAT paid on rent, consulting fees, logistics, IT services, legal fees, and other business services is now claimable as input VAT, provided the purchase is for business use and you hold a valid VAT invoice from a registered supplier.
