How to calculate net salary in Nigeria after tax and pension deductions
The figure that lands in your bank account every month is the result of several quiet deductions applied between your gross salary and the credit alert. Pension contributions, housing fund payments, health insurance, and income tax all take their share before the money reaches you, and for many employees the gap between gross and net pay is wider than they expect. The 2026 tax reforms changed the arithmetic too, introducing fresh income tax bands and a new rent relief that materially alters how much PAYE leaves a payslip. Working through the calculation yourself — with a calculator, a payslip, and about fifteen minutes — shows exactly where every naira goes and whether your employer is deducting the right amounts.
The deductions that come off before tax
Nigerian payroll applies two categories of deductions, and the order matters. Pre-tax deductions come off first and shrink the income that tax is calculated on; post-tax deductions apply afterwards and simply reduce the final amount. The statutory pre-tax items are the pension contribution and, where applicable, the National Housing Fund contribution.
Under the Contributory Pension Scheme, employees contribute a minimum of 8% of their monthly emoluments — typically the combination of basic salary, housing allowance, and transport allowance — while the employer adds at least 10% on top. Your own 8% comes off your payslip; the employer’s share never touches your take-home, but it does accumulate in the same Retirement Savings Account. The National Housing Fund deduction stands at 2.5% of basic salary, mandatory in the public sector and voluntary in the private sector, where many employers deduct it only when the employee opts in. Some employers additionally deduct health insurance contributions under the National Health Insurance Authority scheme, commonly split 5% employee and 10% employer of basic salary, though participation depends on the company’s arrangement.
None of these items are money lost. Pension contributions build retirement savings you control, NHF balances feed into mortgage eligibility, and health insurance carries its own benefit — but every one of them must be accounted for when predicting the alert that arrives on payday.
The step-by-step calculation
The full calculation runs annually, then divides by twelve for the monthly figure, because Nigeria’s PAYE system works on yearly income bands. Follow the sequence below and each figure flows into the next:
- Add up your annual gross income — twelve months of salary, allowances, and regular benefits that form part of your emoluments
- Calculate your annual pension contribution at 8% of the pensionable components of your pay
- Calculate your NHF contribution at 2.5% of your annual basic salary, if you participate
- Identify the components that are tax-exempt under the law, which exclude your pension and NHF contributions
- Apply the rent relief — 20% of the annual rent you actually paid, capped at ₦500,000, provided you can document it
- Subtract pension, NHF, and rent relief from gross income to arrive at your chargeable income
- Apply the progressive tax bands to the chargeable income in stages, not at a single rate
- Divide the annual tax by twelve to get your monthly PAYE deduction
- Subtract PAYE, pension, NHF, and any post-tax items from your monthly gross to reach net salary
The most common mistake sits at step seven: applying one tax rate to the whole income instead of working through the bands in stages. A person earning ₦5 million a year pays 0% on the first ₦800,000 and 15% on the next ₦2.2 million before the higher rates ever touch anything — which is why the effective rate always lands far below the top band.
The 2026 PAYE tax bands
Since January 2026, personal income tax has run on the graduated schedule introduced by the Nigeria Tax Act 2025, which replaced the older seven-to-24% structure and the consolidated relief allowance. The bands below apply to annual chargeable income:
| Annual chargeable income | Tax rate | Amount payable in that band |
|---|---|---|
| First ₦800,000 | 0% | Nil |
| Next ₦2,200,000 | 15% | Up to ₦330,000 |
| Next ₦9,000,000 | 18% | Up to ₦1,620,000 |
| Next ₦13,000,000 | 21% | Up to ₦2,730,000 |
| Next ₦25,000,000 | 23% | Up to ₦5,750,000 |
| Above ₦50,000,000 | 25% | 25% of every naira above ₦50 million |
The structure protects low earners deliberately: anyone whose chargeable income falls within the first ₦800,000 pays no personal income tax at all, which covers minimum-wage earners and a large share of entry-level salaries once pension and other deductions have done their work. The rates climb gradually from there, and the middle of the schedule — 15% and 18% — is where most Nigerian professionals find themselves.
A worked example with real numbers
Consider an employee with a monthly package of ₦500,000 — a basic salary of ₦300,000, housing allowance of ₦100,000, and transport allowance of ₦100,000 — paying annual rent of ₦1,200,000. The annual gross income is ₦6,000,000. Pension comes to 8% of the ₦6 million emoluments, which is ₦480,000 a year, and NHF adds 2.5% of the ₦3.6 million basic salary, or ₦90,000. The rent relief equals 20% of ₦1,200,000, which is ₦240,000 — well under the ₦500,000 cap.
Chargeable income is therefore ₦6,000,000 minus ₦480,000, ₦90,000, and ₦240,000 — a figure of ₦5,190,000. The tax falls out as follows: nothing on the first ₦800,000, ₦330,000 on the next ₦2.2 million at 15%, and ₦394,200 on the remaining ₦2,190,000 at 18%. Annual PAYE totals ₦724,200, which divides into a monthly deduction of ₦60,350.
The monthly payslip then reads: gross ₦500,000, minus pension of ₦40,000, minus NHF of ₦7,500, minus PAYE of ₦60,350 — leaving a net salary of ₦392,150. Roughly 22% of gross never reaches the account, but ₦40,000 of that is retirement savings rather than tax, and the effective tax rate sits near 12% thanks to the reliefs. Lower salaries are treated even more gently: an employee earning ₦200,000 monthly on the same structure ends up with a taxable income of ₦1,932,000 and monthly PAYE of just ₦14,150.
The rent relief most employees never claim
The rent relief is the quiet headline of the 2026 reforms, and it goes unused more often than not. It deducts 20% of your actual annual rent from taxable income, up to a maximum of ₦500,000, and it applies whether you live in Lagos, Kano, or a rented flat in any state. The condition is documentation: your employer needs a rent receipt or equivalent proof before the relief can be worked into the monthly PAYE calculation, and the tax authority may ask you to declare the actual amount paid.
For an employee paying ₦2.5 million rent in a year, the relief runs to the full ₦500,000 cap — enough to reduce annual tax by tens of thousands of naira at the middle bands. Homeowners do not qualify, and tenants who share a property can each claim only the portion of rent they personally bear. Leaving this relief unclaimed is effectively volunteering to pay more tax than the law requires.
How to increase your take-home pay legally
Once the mechanics are clear, a few levers move net pay upward without touching the tax law’s edges. The options below are all legitimate, and their effect differs depending on your salary level:
- Submit your rent receipts to your employer so the rent relief is factored into monthly PAYE instead of waiting for an annual refund
- Check that your pension deduction is calculated on the correct components — basic, housing, and transport — and that your employer is not over-deducting
- Make voluntary pension contributions, which are tax-deductible up to the regulatory cap and grow tax-free in your Retirement Savings Account
- Confirm your NHF status in the private sector, where participation is voluntary and joining it buys a future mortgage benefit while reducing taxable income
- Review your salary structure with your employer, since allowances outside the pensionable base reduce the statutory deduction load
None of these involve hiding income or inflating expenses. The reliefs exist precisely to be claimed, and the pension route doubles as forced savings that compound toward retirement — a rare deduction that leaves you objectively wealthier over time.
When your payslip does not add up
Discrepancies between calculated and actual net pay usually trace to a handful of sources: an employer still running the old pre-2026 tax bands, a relief never declared, a pension base defined differently in your contract than you assumed, or post-tax deductions — cooperative savings, union dues, salary advances — that nobody itemised for you. Compare your payslip line by line against your own calculation, and raise specific figures with HR rather than a general complaint. Employers using payroll software typically updated to the 2026 bands early in the year, but smaller employers and manual payrolls are the likeliest sources of error, and state tax authorities expect corrections within the same assessment year.
Common questions about net salary in Nigeria
Is the employer’s 10% pension contribution deducted from my salary? No. Only the employee’s 8% comes off your payslip. The employer’s share is paid in addition to your gross and both amounts flow into your Retirement Savings Account.
Do I pay tax on a salary of ₦100,000 a month? Almost certainly not. Once pension and reliefs reduce chargeable income below ₦800,000 a year, the first tax band applies at 0% and no PAYE should appear on the payslip.
What happens to my pension if I change jobs? The balance stays in your Retirement Savings Account and transfers with you; only the contributions from the new employer add to it. The account is yours regardless of who employs you.
Is NHF compulsory for private-sector workers? Enforcement has been relaxed in the private sector, where participation is generally voluntary. Public-sector employees contribute automatically, and the 2.5% of basic salary remains the standard rate either way.
Why does my net pay differ from a colleague on the same gross? Rent relief claims, pensionable components, NHF participation, and post-tax deductions like cooperatives all differ between individuals. Two identical gross salaries can produce noticeably different net figures purely on declared reliefs.
Know your payslip before it knows you
A payslip you cannot read is a payslip you cannot audit, and the difference between gross and net pay is too large at most salary levels to leave unexamined. Run the numbers on your own package using the steps above, verify the 2026 bands are the ones your employer actually applies, and claim the rent relief if you are paying rent. The calculation takes minutes, the corrections it surfaces can be worth real money every month, and the habit of checking never stops paying — because the only person watching your deductions as closely as the tax authority should be you.
