Why this one

Most Nigerian tax calculators online are now wrong

The Nigeria Tax Act 2025 abolished the Consolidated Relief Allowance (CRA), a long-standing component of Nigeria's PAYE computation. From 1 January 2026, the CRA no longer applies. The new regime introduces a 0% tax band on the first ₦800,000 of chargeable income and a Rent Relief deduction of 20% of annual rent actually paid, capped at ₦500,000. This represents a structural redesign of the personal income tax system, not merely a change in tax rates.

A calculator that still applies the CRA will understate tax for most earners and overstate it for some. Ours does not, and our test suite contains an explicit assertion that the CRA has not crept back in, because the most likely way this tool becomes wrong is a well-meaning update that reintroduces it.

Every rate here carries its statutory source on screen. If we cannot evidence a rate, we say so rather than publishing it quietly.

Questions

About this calculator

What changed under the Nigeria Tax Act 2025?
The Act, effective 1 January 2026, replaced the personal income tax bands and abolished the Consolidated Relief Allowance entirely, substituting a rent relief of 20% of rent paid capped at ₦500,000. It also set a 0% companies income tax rate for small companies (turnover at or below ₦100 million and fixed assets at or below ₦250 million) and introduced a 4% development levy on the assessable profits of larger companies. Any calculator still applying the CRA produces a materially wrong figure from 2026 onward.
Is my data sent anywhere?
No. Every calculation runs in your browser. The figures you type are never transmitted to us, never stored, and never logged. There is no signup and no email capture on this tool.
Can I submit these figures to the tax authority?
No. This is an indicative guide, not a tax computation. It cannot account for reliefs, exemptions, elections and prior-year adjustments that depend on facts it does not ask for. Use it to understand your likely position and to sanity-check a figure you have been given, then have the computation done properly before you file.
Why is the withholding tax calculator marked as awaiting review?
Withholding rates sit in subsidiary regulation rather than the Act, and vary by recipient type, residence and exemption status. They are the figures most likely to be wrong in a published calculator. Rather than present them with unearned confidence, we flag them until our tax partner has signed off the table. The other four calculators apply rates drawn directly from the Act.
How often is this updated?
Every rate lives in a single, dated rule set keyed by tax year, so a change in the law is one edit rather than a hunt through the code. When a new tax year takes effect we add its figures and keep the previous year selectable, because prior-year computations do not stop being needed.

The number surprised you?

There is usually a legitimate structure that produces a better outcome, and occasionally an exposure worth addressing before it is assessed. Either way, it is a conversation worth having.
