Nigeria Income Tax Brackets 2026 Explained (Nigeria Tax Act 2025)

Nigeria didn't just adjust its tax brackets for 2026 — it replaced an entire deduction mechanism. The old Consolidated Relief Allowance gave everyone the same flat percentage-of-income break regardless of their actual living costs. The new system ties relief directly to what you actually paid in rent, which means two people with identical salaries can now owe genuinely different tax depending on their housing situation alone.

2026 tax brackets (Nigeria Tax Act 2025)

Effective January 1, 2026, the Act replaced the previous ₦300,000 tax-free threshold with ₦800,000 — a meaningful change for anyone at the lower end of the income scale.

Rent relief, the new deduction mechanism

The old Consolidated Relief Allowance is gone entirely, replaced by rent relief: 20% of annual rent actually paid, capped at ₦500,000. This directly ties the deduction to real housing costs instead of a flat formula based on income alone — and it means you now need actual rent payment records to claim it, not just a percentage plugged into a calculation.

Running real numbers through it

₦3,600,000 gross income, ₦1,000,000 paid in annual rent: rent relief comes to 20% × ₦1,000,000 = ₦200,000. Taxable income drops to ₦3,400,000, landing in the ₦3,000,000–₦12,000,000 band. Tax works out to ₦330,000 base plus 18% of the ₦400,000 above that band's floor, for ₦402,000 total — hand-checked, an effective rate of 11.2% on the full gross income.

What the mandatory pension deduction is actually worth

Nigeria's 8% mandatory pension contribution under the Contributory Pension Scheme is fully deductible before tax bands apply — and skipping it in a manual estimate genuinely overstates the real bill. Take ₦5,000,000 gross with no other reliefs: tax comes to ₦690,000. Subtract the mandatory 8% pension contribution (₦400,000) first, and taxable income falls to ₦4,600,000, cutting tax to ₦618,000 — a real saving of ₦72,000, roughly 18% of the contribution itself, hand-verified.

Common mistakes

• Using the old ₦300,000 threshold. Replaced by ₦800,000 starting January 1, 2026 — a frequent source of outdated online estimates.
• Still trying to claim the old CRA formula. Rent relief replaced it entirely, and it requires actual rent payment records, not just a percentage-of-income calculation.
• Entering raw gross salary without subtracting mandatory pension first. The 8% Contributory Pension Scheme deduction happens automatically and is fully deductible before tax applies.

Why Nigeria's flat penalty hits small taxpayers hardest

Nigeria's penalty structure under the Nigeria Tax Administration Act 2025 is unusual among the countries in this guide because the filing penalty is a flat naira amount, not a percentage of your tax bill — which makes it disproportionately painful for smaller taxpayers specifically.

• Late filing penalty: ₦100,000 for the first month of default, then ₦50,000 for every additional month — this applies regardless of how much tax you actually owe, even if your real liability is far smaller than the penalty itself.
• Late payment penalty: 10% of the unpaid tax, plus interest at the Monetary Policy Rate (MPR), which moves with monetary policy so isn't a fixed figure year to year.
• False declarations can trigger fines up to ₦1,000,000, imprisonment up to 3 years, or both — a genuinely serious escalation beyond the administrative penalties above.

Case example: ₦402,000 tax bill, 3 months late

Now imagine that ₦3,600,000/₦402,000 return from above sitting unfiled for 3 months past its deadline.

• Late filing penalty: ₦100,000 for the first month, plus ₦50,000 × 2 additional months = ₦200,000 total.
• Late payment penalty: 10% of ₦402,000 = ₦40,200, plus MPR interest on top (treat as a smaller additional amount, since MPR moves).
• Total: roughly ₦642,000 against an original ₦402,000 tax bill — the filing penalty alone is worth more than the entire underlying tax debt, and it would be exactly the same ₦200,000 even if the original tax owed were a fraction of this size. This is the single most important thing to understand about Nigeria's penalty structure: the flat filing penalty hits smaller taxpayers proportionally far harder than larger ones.

Stopping the monthly penalty from compounding further

• File immediately, even without full payment. The flat monthly filing penalty keeps accumulating for every additional month you delay — stopping that clock matters more here than almost anywhere else in this guide, precisely because the penalty is flat rather than tied to your actual tax owed.
• Bring the balance down whenever you're able to, since both the 10% penalty and the MPR interest scale with whatever's still outstanding.
• Respond to any NRS compliance notice rather than ignoring it. The NRS now uses automated data analytics to cross-check payroll, bank records, and filings, and non-response tends to escalate matters toward audit and enforcement rather than resolving quietly.
• Engage a tax professional for anything beyond a straightforward salaried return, particularly if multiple months or years are involved — the interaction between accumulating monthly filing penalties, payment penalties, and interest can be genuinely difficult to reconstruct accurately on your own once it's been running for a while.

What's still deductible after the 2025 reform stripped out CRA

Beyond rent relief and mandatory pension contributions covered above, several other deductions remain available under the Nigeria Tax Act 2025, though all now require documentary evidence to claim — informal declarations without receipts are no longer sufficient:

• Voluntary pension contributions beyond the mandatory 8%, still under the Pension Reform Act, remain deductible.
• National Housing Fund (NHF) contributions and National Health Insurance Scheme (NHIS) contributions are both deductible.
• Life insurance and annuity premiums on your own life or your spouse's are deductible, as is mortgage interest on a loan taken specifically to develop an owner-occupied residential house.

A genuinely major structural change worth knowing if you have investments: capital gains are no longer taxed at a flat 10% rate. From 2026, gains on shares, property, and other chargeable assets are folded into your ordinary personal income and taxed at your regular income tax band, up to 25% for high earners. Small investors get some protection — share disposals are exempt if total annual proceeds are ₦150,000,000 or less and total gains are ₦10,000,000 or less, but exceeding either threshold makes all your gains for the year taxable, not just the excess.

Estate planning: no inheritance tax, but a real capital gains wrinkle on later sale

Nigeria abolished Estate Duty back in 1979, and Section 145 of the Nigeria Tax Act 2025 explicitly confirms that "no charge to tax shall arise solely by reason of the devolution of an estate upon heirs or successors" — receiving an inheritance itself is entirely tax-free, regardless of value. What changes under the new law is what happens afterward: heirs are deemed to acquire inherited assets at their market value on the date of death, resetting the cost base. This is actually favorable — it means capital gains tax on a later sale applies only to appreciation after you inherited the asset, not the full gain the deceased would have faced. Two things do remain taxable regardless: rental income earned from an inherited property going forward, and any gain on eventual sale beyond the stepped-up value (though a principal-residence exemption can apply if it becomes your main home). If you're managing a family estate with multiple heirs, get the date-of-death valuation properly documented at the time of inheritance — it's the number that determines everyone's eventual tax exposure, and reconstructing it years later is far harder than recording it at the time.

Note for anyone used to the old name: the Federal Inland Revenue Service (FIRS) was officially renamed the Nigeria Revenue Service (NRS) effective January 1, 2026, under the Nigeria Tax Act 2025 reforms. For current rates, forms, and filing, check the NRS directly at nrs.gov.ng — existing TINs remain valid under the new agency.
