Nigerian Tax Calculator 2026 — Understand Your Tax Liability Under the New Rules

Nigeria's tax system changed significantly from January 1, 2026, following the commencement of the Nigeria Tax Act 2025.

But "Nigeria tax" is not one single calculation.

The tax that applies to you depends on who you are, what you earn, what your business does, and the type of transaction involved.

An employee may be dealing primarily with Personal Income Tax and PAYE. A company may need to consider Corporate Income Tax, Development Levy, VAT and withholding tax. An individual disposing of certain assets may also have Capital Gains Tax implications.

This guide brings the main 2026 tax calculations together in one place and points you toward the more detailed calculators for each area.

Which Nigerian Tax Do You Need to Calculate?

Start with the type of income or activity you are dealing with.

You earn income personally

You will generally be looking at Personal Income Tax (PIT).

This includes employment income and, depending on your circumstances, income from business, investments and other sources.

For employees, PAYE is the mechanism through which employment-related personal income tax is deducted.

See: Nigeria PAYE Calculator 2026

You operate a company

You may need to calculate Corporate Income Tax (CIT).

The 2026 corporate tax framework distinguishes between small companies and other companies.

Under the current rules, a qualifying small company has gross turnover of not more than ₦100 million and fixed assets not exceeding ₦250 million, and is subject to a 0% CIT rate. Other Nigerian companies are generally subject to the applicable corporate income tax rate.

Corporate calculations can also involve Development Levy, capital allowances, withholding-tax credits and other adjustments.

See: Nigeria Corporate Tax Calculator 2026

You sell taxable goods or services

You may need to consider Value Added Tax (VAT).

VAT is an indirect tax applied to taxable supplies, with the standard rate remaining 7.5% under the current framework.

VAT treatment can depend on the nature of the goods or services and whether an applicable exemption or zero-rating provision applies.

See: VAT Calculator Nigeria

You dispose of an asset or investment

You may need to consider Capital Gains Tax (CGT).

The treatment of capital gains changed substantially under the new tax framework, particularly for individuals, where qualifying capital gains are incorporated into the personal income tax computation rather than simply applying the former flat 10% approach.

Nigeria Tax Rates at a Glance

There is no single "Nigeria tax rate."

Different taxes have different rules.

How the 2026 Personal Income Tax Calculation Works

For individuals, the calculation generally starts with relevant income and then considers applicable deductions and reliefs before applying the progressive tax bands.

The first ₦800,000 of taxable income is taxed at 0%. The subsequent portions move through the progressive bands.

The former Consolidated Relief Allowance has been removed under the new framework.

Eligible taxpayers can instead benefit from specific reliefs, including rent relief subject to the statutory conditions and ₦500,000 maximum.

This is why a simple calculation such as:

Annual salary × tax rate

does not accurately describe how Nigerian personal income tax works.

For the detailed calculation, see our Nigeria PAYE Calculator 2026.

How Corporate Tax Works in 2026

Corporate tax requires a different approach.

A company's taxable position is not necessarily the same as the accounting profit shown in its financial statements.

The calculation can require adjustments to arrive at assessable profit and taxable profit, including treatment of:

• Disallowable expenses

• Capital allowances

• Qualifying deductions

• Withholding-tax credits

• Development Levy

• Capital gains

• Applicable exemptions

Qualifying small companies receive significant relief under the new framework, while companies outside the small-company definition are subject to the applicable corporate tax provisions.

For the detailed calculation, see our Nigeria Corporate Tax Calculator 2026.

VAT Is Different From Income Tax

VAT should not be confused with profit tax.

VAT is generally collected on taxable supplies and accounted for to the relevant tax authority.

A business can therefore have:

high sales + low profit

or

low sales + high profit

without that automatically determining its VAT position.

The VAT calculation depends on taxable supplies, applicable VAT treatment, input VAT rules and other provisions.

For a detailed explanation, see our VAT Calculator Nigeria page.

What About Capital Gains?

Capital gains are another area where the new framework changed the way individuals should think about tax.

A gain from disposing of an asset is not necessarily treated as a completely separate flat-rate calculation.

For individuals, qualifying gains can form part of the personal income tax computation under the new framework, subject to the applicable rules and exemptions.

There are also specific provisions concerning transactions such as share disposals.

Because CGT can become complicated quickly, it is better to treat it as its own calculation rather than trying to build everything into one generic tax formula.

Why Your Tax Calculation Starts With Good Records

A calculator can apply a formula.

It cannot fix incomplete information.

Before calculating tax, you may need to know:

• How much income was actually received

• Which expenses were incurred

• Which expenses are deductible

• What assets were purchased

• What assets were disposed of

• What VAT was charged

• What VAT may be recoverable

• What withholding tax was deducted

• What payroll deductions were made

• Which reliefs or exemptions apply

This is why tax calculation and financial record keeping are closely connected.

The better the underlying records, the more meaningful the resulting calculation becomes.

The Bottom Line

There is no single formula for "Nigerian tax."

The correct calculation depends on the taxpayer, the income, the transaction and the applicable part of the law.

The Nigeria Tax Act 2025 brought a significant restructuring of the tax framework, effective from January 1, 2026.

Rather than guessing which percentage applies, start by identifying what kind of tax you are actually dealing with.

Then use the appropriate calculation.
