Nigerian tax calculators

Six free tools for working out what you owe under the Nigeria Tax Act 2025 — personal income tax, PAYE, VAT, company tax, foreign-currency income, and whether you need to file at all. Each runs in your browser. Nothing you type is sent anywhere, and none of them need an account.

Where the figures come from

Every rate and threshold these tools apply is read from the Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025 as gazetted, not from secondary summaries — several of which still quote superseded figures from the certified bill. The small-company and VAT thresholds are the common example: widely reported as ₦100 million, but ₦50 million in the gazette.

Each figure in the codebase carries the section it derives from and the date it was last checked against the primary source, and the explanatory tables on each calculator are generated from those same constants — so the prose cannot drift away from the arithmetic.

These are estimates to help you plan and prepare. Your final assessment is determined by the Nigeria Revenue Service or your State Internal Revenue Service. TaxJeje is not affiliated with either.
