VAT COMPUTATION IN NIGERIA 2025: COMPLETE GUIDE TO INPUT TAX, OUTPUT TAX, OPENING AND CLOSING INVENTORY TREATMENT

Nigeria’s VAT landscape has changed. The new Nigeria Tax Act (NTA) 2025 and Tax Administration Act (NTAA) 2025 took effect on 1 January 2026, replacing the old Value Added Tax Act. The standard VAT rate remains 7.5%, but almost everything else has shifted .

Get the computation wrong, and you will overpay tax or face penalties. Get it right, and you unlock significant cash flow benefits. This guide breaks down everything: output VAT, input VAT, the treatment of opening and closing inventory, and exactly how to compute your VAT payable under the NTA 2025. Let us get into it.

The Pain Points: Why Nigerian Businesses Struggle with VAT Computation

Confusion Between Input VAT and Output VAT

Many business owners do not understand the difference. Input VAT is what you pay to suppliers. Output VAT is what you charge customers. The formula is simple: VAT Payable = Output VAT – Allowable Input VAT . But the simplicity ends there. Not all input VAT is claimable. And the rules under the new law have changed significantly.

The Old Limitation on Input VAT Claims

Under the old regime, input VAT deduction was severely restricted. You could only claim VAT on goods purchased directly for resale or goods used in the direct production of taxable products . VAT on services, overheads, and fixed assets was not claimable. You simply ate the cost.

That has changed with the NTA 2025. The scope of recoverable input VAT has been broadened to allow deductions on services and fixed assets—provided they relate to taxable supplies . This is a game-changer for service providers and capital-intensive businesses.

Inventory Complications: Opening and Closing Stock

Inventory creates real headaches in VAT computation. Here is the problem: you pay input VAT when you purchase stock. But you only generate output VAT when you sell that stock. If you have a large closing inventory at the end of the period, you have paid VAT on goods you have not yet sold. Can you claim that input VAT immediately? The answer is yes, but the timing mismatch creates cash flow challenges.

Cash Flow Strain from VAT Timing Mismatches

VAT is due on the accrual basis. You must remit output VAT monthly, even if customers have not paid you yet. Meanwhile, you may have paid input VAT to suppliers. The timing mismatch between paying VAT to suppliers and collecting VAT from customers can strain cash flow severely.

Filing Deadlines and Penalties

VAT returns must be filed on or before the 21st day of the month following the period in question . VAT withheld at source must be remitted to the Nigeria Revenue Service (NRS) no later than the 14th day of the following month.

Penalties for late filing are steep. The NTAA 2025 provides that failure to file returns attracts a penalty of N100,000 for the first month and N50,000 for each additional month . Failure to remit VAT attracts the principal amount, a 10% annual penalty, and interest at the Central Bank of Nigeria Monetary Policy Rate .

The Cost of Getting It Wrong

Many businesses are discovering the hard way that VAT errors are expensive. A retail company in Lagos recently had its input VAT claim of N8 million disallowed because it could not produce valid invoices. The NRS imposed back taxes, interest, and penalties totaling N12 million. The company’s profit for the quarter was wiped out.

That is not an isolated case. The NRS is actively auditing VAT returns. They know this is where most businesses are vulnerable. If you are not prepared, you are leaving yourself exposed to significant financial risk.

Output VAT: What You Charge Customers

Definition

Output VAT is the VAT you charge your customers when you sell taxable goods or services. It is collected on behalf of the government. It is not your money. You are simply a middleman.

Calculation

Output VAT = Selling Price (VAT-exclusive) × 7.5%

Example:

You sell goods worth N1,000,000 (exclusive of VAT)

Output VAT = N1,000,000 × 7.5% = N75,000

Total invoice amount = N1,075,000

When Output VAT is Due

VAT is due on the earlier of the date of supply, the date of invoice, or the date of payment. Under the accrual basis, you must remit output VAT monthly, even if customers have not paid.

Zero-Rated Supplies

Zero-rated supplies have a VAT rate of 0%, but input VAT can still be claimed . Examples include basic food items, medical and pharmaceutical products, educational books and materials, fertilizers, exported goods and services, electricity generated by GENCOs, medical services, and tuition relating to nursery, primary, secondary, or tertiary education .

VAT-Exempt Supplies

Exempt supplies are not subject to VAT, and input VAT on purchases related to exempt supplies is NOT claimable . Examples include oil and gas exports, baby products, locally manufactured sanitary towels, military hardware, shared passenger road-transport service, agricultural equipment, residential rent, financial services, money and securities, government licences, petroleum products, and renewable energy equipment .

Input VAT: What You Pay to Suppliers

Definition

Input VAT is the VAT you pay to your suppliers when you purchase taxable goods or services for your business .

What Is Now Claimable Under NTA 2025

The big change under the NTA 2025 is that input VAT on services and fixed assets is now claimable, provided the input VAT is attributable to the use, consumption, or supply of taxable outputs .

Previously, only VAT on :

Goods purchased for resale

Goods which form the stock-in-trade used for direct production

Now, VAT on the following is also claimable :

Services (rent, consultancy, IT, logistics, professional fees, legal services, repairs)

Overheads (power, internet, operations)

Fixed assets and equipment

All taxable supplies used to make taxable outputs

Important: If a cost relates to both taxable and exempt activities, the input VAT must be apportioned. Only the portion attributable to taxable supplies is claimable. The concluding part of Section 155(4) of the NTA states: “but only to the extent that the input tax was incurred for the purpose of consumption, use or supply in the course of making taxable supplies” .

What Is Not Claimable

Input VAT on purchases used to make exempt supplies remains non-claimable .

Example of Input VAT Recovery

A manufacturing company buys raw materials for N1,000,000 and pays VAT of N75,000 (Input VAT). The company also pays a consultant N200,000 plus VAT of N15,000. Under the new rules, both the N75,000 and N15,000 are claimable as input VAT, provided the supplies relate to taxable outputs.

Input VAT Recovery Period

The NTA provides that input VAT may be claimed within five years from the end of the tax period in which it was incurred .

VAT Computation: The Complete Formula

Basic Formula

VAT Payable to Government = Output VAT – Allowable Input VAT

Worked Example

Scenario:

You sell goods worth N1,500,000 (VAT-exclusive)

You purchase raw materials worth N1,000,000 (VAT-exclusive)

You pay for professional services worth N200,000 (VAT-exclusive)

Computation:

Item	VAT-exclusive Value	VAT (7.5%)
Output VAT
Sales	N1,500,000	N112,500
Input VAT (Claimable)
Raw Materials	N1,000,000	N75,000
Professional Services	N200,000	N15,000
Total Input VAT		N90,000
VAT Payable		N112,500 – N90,000 = N22,500

You remit only N22,500 to the NRS.

Excess Input VAT (Input VAT > Output VAT)

If Input VAT exceeds Output VAT, the excess becomes a credit. You can carry it forward to offset future output VAT or request a cash refund from the NRS. Refund requests must be made within 12 months after the relevant transaction, and approved refunds must be issued within 30 days .

Timing of Refund Requests

Where a valid request is received from a taxable person for VAT refund, the NRS shall not later than 30 days of the receipt of that request refund the tax or the amount shall be eligible for set-off against any tax liability of the taxpayer .

Opening and Closing Inventory Treatment

The Core Principle

Inventory is considered part of a business’s assets and is not subject to VAT until it is sold. When inventory is sold, VAT is charged on the final selling price.

Treatment of Opening Inventory

Opening inventory represents stock on hand from the previous period. The VAT on this stock was claimed as input VAT in the period it was purchased. There is no additional VAT adjustment for opening inventory in the current period.

Treatment of Closing Inventory

Closing inventory represents unsold stock at the end of the period. The VAT on closing inventory was claimed as input VAT in the current period (when the stock was purchased). This is correct because input VAT is claimable in the period of purchase, regardless of when the stock is sold.

The Timing Mismatch

Here is the key issue: You claim input VAT when you purchase stock. But you only generate output VAT when you sell that stock. If you have large closing inventory, you may have claimed significant input VAT with no corresponding output VAT yet. This can create a VAT credit position.

Practical Example: Inventory Treatment

Scenario:

Opening inventory: N1,000,000 (VAT already claimed in previous period)

Purchases during period: N5,000,000 (Input VAT claimed: N375,000)

Sales during period: N4,000,000 (Output VAT: N300,000)

Closing inventory: N2,000,000

Computation:

Item	Value (excl. VAT)	VAT (7.5%)
Output VAT on Sales	N4,000,000	N300,000
Input VAT on Purchases	N5,000,000	N375,000
VAT Payable / (Credit)		(N75,000)

Result: The business has an excess input VAT of N75,000. This can be carried forward as a credit or refunded. The closing inventory of N2,000,000 represents goods on which input VAT of N150,000 (N2,000,000 × 7.5%) was claimed in the current period. This is correct because the VAT was paid at the time of purchase. The business will generate output VAT when these goods are eventually sold in a future period.

Key Takeaway for Inventory

Input VAT on inventory is claimable when inventory is purchased, not when it is sold. This is the fundamental principle for VAT treatment of inventory. Businesses with seasonal fluctuations should plan for VAT credit positions during high-purchase, low-sales periods. Closing inventory adjustments ensure Input Tax does not exceed Output Tax .

Registration, Filing, and Penalties

Registration Requirements

Registration is required for both residents and non-residents carrying on businesses in Nigeria upon commencement. Failure to register for VAT upon commencement attracts a penalty of N50,000 for the first month and N25,000 for each subsequent month .

Filing Deadlines

VAT returns are required to be submitted monthly, on or before the 21st day of the month following the month of transaction . In any month where there is no transaction, the law requires that a nil return is rendered .

Penalties for Non-Compliance

Offence	Penalty
Failure to register for VAT	N50,000 for the first month, N25,000 for each subsequent month
Failure to submit VAT returns	N50,000 for the first month, N25,000 for each subsequent month
Failure to remit VAT	10% per annum of unremitted amount plus interest at CBN rate
Late filing (NTAA 2025)	N100,000 for the first month, N50,000 for each additional month
