Tax Deductions Most Nigerian Employees Miss: Pension, NHF, NHIS

Three payroll deductions reduce your PAYE but most Nigerian employees get them wrong. How pension, NHF, and NHIS deductions actually work under the NTA 2025.

Every month, your payslip shows deductions — pension, NHF, NHIS — before arriving at your net pay. Most employees glance at the net figure and move on. What they do not realise is that these same deductions are supposed to reduce the income on which PAYE is calculated. When they are applied correctly, you pay less tax. When they are applied incorrectly — or not applied at all in the PAYE computation — you overpay every single month, twelve months a year, for the entire duration of your employment.

The Nigeria Tax Act 2025 specifies exactly how pension, NHF, and NHIS reduce your chargeable income. The problem is not the law. The problem is that payroll systems misconfigure the deductions, employees do not check, and HR departments do not catch the errors.

This guide shows you what each deduction should look like on your payslip, how it should reduce your PAYE, what the most common errors are, and how to fix them.

Why These Deductions Matter More Than You Think

Under the NTA 2025, PAYE is computed on your chargeable income — which is your gross income minus allowable deductions. Every naira deducted from your gross income before the tax bands are applied reduces the amount of income subject to tax. At the 18% band, a ₦100,000 deduction saves you ₦18,000 in tax. At the 25% band, it saves ₦25,000.

Pension, NHF, and NHIS are deducted from your salary regardless — you pay them whether they reduce your PAYE or not. The question is whether your payroll system actually uses them to reduce your taxable income. If it does not, you are paying the contributions and paying PAYE on the income that should have been sheltered by those contributions. You are taxed as if the deductions do not exist.

This is not a theoretical problem. It is one of the most common payroll errors in Nigeria, and it costs affected employees tens of thousands — sometimes hundreds of thousands — of naira in excess PAYE every year.

Deduction 1: Pension — The Biggest and Most Misconfigured

The employee pension contribution is the single largest deduction available to most Nigerian employees. Under the Pension Reform Act 2014, employees contribute a minimum of 8% of their pensionable earnings to a Retirement Savings Account (RSA) held by a licensed Pension Fund Administrator (PFA). Under the NTA 2025, this contribution is deducted from gross income before PAYE is computed.

The Correct Pension Base

This is where most errors occur. The pensionable base under the PRA 2014 is Basic Salary + Housing Allowance + Transport Allowance. Not gross salary. Not total emoluments. Not basic salary alone. Only these three components.

If your monthly gross salary is ₦800,000 and your package breaks down as follows:

The correct pensionable base is ₦640,000 (Basic ₦400,000 + Housing ₦160,000 + Transport ₦80,000). Your employee pension contribution is 8% of ₦640,000 = ₦51,200 per month.

The Three Common Pension Errors

Error 1: Pension Computed on Gross Salary

Some payroll systems compute pension on the full gross salary — ₦800,000 in this example — instead of the ₦640,000 pensionable base. Your pension deduction would be 8% of ₦800,000 = ₦64,000 instead of ₦51,200. You are over-contributing ₦12,800 per month (₦153,600 per year). While the excess goes into your RSA (which is not lost), it reduces your take-home pay unnecessarily. More importantly, if the payroll system uses the inflated pension figure to reduce your taxable income, the PAYE computation may appear correct on the surface — but it masks a structural error in your package.

Error 2: Pension Computed on Basic Salary Only

The opposite error. Some payroll systems compute pension on basic salary alone — ₦400,000 in this example — excluding housing and transport. Your pension contribution would be 8% of ₦400,000 = ₦32,000 instead of ₦51,200. You are under-contributing ₦19,200 per month. Your pension deduction for PAYE purposes is smaller than it should be, meaning your chargeable income is higher and your PAYE is higher. You are paying more tax than you should and building a smaller pension at the same time.

Error 3: Pension Deducted From Salary But Not From PAYE Computation

This is the most damaging error because it is invisible on a casual payslip review. Your employer deducts ₦51,200 from your salary — you can see it on the payslip — but the payroll system does not subtract the pension from your gross income when computing PAYE. You are paying pension and paying PAYE on the income that should have been sheltered by the pension contribution.

The monthly PAYE difference on ₦51,200 at the 18% band is ₦9,216. Over 12 months, that is ₦110,592 in excess PAYE per year — money you should not have paid.

How to Check Your Payslip for Pension Errors

1. Identify your Basic Salary, Housing Allowance, and Transport Allowance on the payslip
2. Add them: this is your pensionable base
3. Multiply by 8%: this is the correct employee pension contribution
4. Compare this to the pension deduction shown on your payslip — if the numbers differ, the pension base is wrong
5. Check whether pension is listed as a deduction in the PAYE computation section (not just the salary deduction section) — if it is not, pension is being deducted from your pay but not from your taxable income

If you find an error, raise it with your HR or payroll department immediately. If the error has persisted for months or years, you may be entitled to a refund of excess PAYE — discuss this with your employer and, if necessary, your State IRS.

Voluntary Pension Contributions

Beyond the mandatory 8%, the PRA 2014 allows employees to make additional voluntary contributions to their RSA. These are also tax-deductible — they further reduce your chargeable income and your PAYE. If you have capacity to save beyond the mandatory contribution and want both the tax benefit and the long-term pension growth, speak to your PFA about increasing your contribution through your employer’s payroll.

Deduction 2: National Housing Fund — Small but Frequently Missed Entirely

The National Housing Fund (NHF) is a 2.5% contribution on basic salary, established under the National Housing Fund Act. Employees earning the national minimum wage or above are required to contribute. The contribution is remitted to the Federal Mortgage Bank of Nigeria (FMBN) and qualifies the contributor for the National Housing Fund mortgage scheme.

Under the NTA 2025, NHF contributions are deductible from chargeable income — they reduce your PAYE in the same way pension does.

How NHF Is Computed

NHF is 2.5% of basic salary only — not Basic + Housing + Transport (that is the pension base), and not gross salary. Using the same example:

• Basic Salary: ₦400,000
• NHF: 2.5% × ₦400,000 = ₦10,000 per month (₦120,000 per year)

The Common NHF Errors

Error 1: NHF Deducted but Not Subtracted From Taxable Income

The same invisible error as with pension. The ₦10,000 is deducted from your salary — it shows on your payslip — but the payroll system does not reduce your taxable income by ₦10,000 before computing PAYE. At the 18% band, this costs you ₦1,800 per month (₦21,600 per year). Not life-changing on its own, but when combined with pension and NHIS errors, the cumulative overpayment becomes significant.

Error 2: NHF Not Deducted at All

Some private sector employers do not participate in the NHF scheme, so no contribution is made and no deduction is available. This is not an error — if your employer does not remit NHF, you do not contribute and cannot claim the deduction. However, if you work for an organisation that should participate (all employers with employees earning the minimum wage or above are technically covered), the absence of NHF may indicate non-compliance by your employer. The consequence for you is a missed deduction that would have reduced your PAYE.

Error 3: NHF Computed on the Wrong Base

NHF is on basic salary only. If the payroll system computes it on gross salary (₦800,000 × 2.5% = ₦20,000 instead of ₦400,000 × 2.5% = ₦10,000), you are over-contributing. The excess does go to the FMBN, but it is more than required and reduces your take-home pay unnecessarily.

How to Verify NHF on Your Payslip

1. Find the NHF deduction line on your payslip
2. Calculate 2.5% of your basic salary
3. Compare: if the figures do not match, the base is wrong
4. Check whether NHF appears in the PAYE computation — if it is deducted from your salary but not from your taxable income, you are overpaying PAYE

Deduction 3: NHIS — The Most Overlooked Deduction

Employee contributions to the National Health Insurance Scheme (NHIS) — or to an employer-operated health insurance plan under the National Health Insurance Authority Act — are deductible from chargeable income under the NTA 2025. This deduction is the most frequently missed of the three, for two reasons: the contribution rate is not standardised across all employers, and many employees do not realise their health insurance contribution qualifies as a tax deduction.

How NHIS Contributions Work

Under the NHIS, the employer contributes a portion and the employee contributes a portion towards a health insurance plan. The exact split varies: some employers cover the full cost (in which case there is no employee contribution to deduct), while others require an employee co-payment — typically between 1.75% and 5% of gross salary or a flat amount.

The employee contribution — whatever you personally pay towards health insurance — is deductible from your chargeable income. If your employer covers 100% and you contribute nothing, there is no deduction available to you. But if you contribute ₦15,000 per month (₦180,000 per year) towards your health insurance plan, that ₦180,000 should reduce your taxable income before PAYE is computed.

The Common NHIS Errors

Error 1: NHIS Contribution Not Reflected in PAYE Computation

The most common error — identical in nature to the pension and NHF errors. Your health insurance contribution is deducted from your salary, but the payroll system does not subtract it from your gross income when computing PAYE. You pay the contribution and pay PAYE on the income that should have been sheltered. At the 18% band, a ₦15,000 monthly NHIS contribution that is not deducted from taxable income costs you ₦2,700 per month (₦32,400 per year) in excess PAYE.

Error 2: Employee Does Not Know They Are Contributing

Some employees are enrolled in employer health insurance plans without realising they are making a personal contribution. The deduction appears on the payslip as “health insurance” or “medical” or a scheme-specific name, and the employee does not connect it to a tax deduction. If you see any health-related deduction on your payslip, confirm whether it is an employee contribution (deductible) or an employer-only cost (not your deduction).

Error 3: Employer-Paid Health Insurance Treated as Employee Income

The reverse problem: some payroll systems add the employer’s health insurance contribution to the employee’s gross income as a benefit in kind and then deduct it — creating a taxable benefit that inflates PAYE. If the employer is paying the health insurance premium directly to the insurer and it is not part of your cash remuneration, it should not be added to your gross income. Check whether your payslip shows a health insurance “benefit” being added to income and then deducted — this inflates your taxable income artificially.

How to Verify NHIS on Your Payslip

1. Identify any health insurance deduction on your payslip
2. Confirm with HR whether this is an employee contribution or an employer-only payment
3. If it is an employee contribution, check whether it appears as a deduction in the PAYE computation
4. If it does not, your taxable income is overstated and your PAYE is too high

Deduction 4: Rent Relief — The Easiest to Claim, the Most Neglected

Rent relief is not a payroll deduction in the same way as pension, NHF, and NHIS — it is a personal relief that reduces your chargeable income. But it belongs in this guide because it is the deduction most commonly missed by employees, and the reason is almost always the same: the employee did not submit rent documentation to their employer.

Under the NTA 2025, rent relief is 20% of annual rent paid, capped at ₦500,000. If you pay ₦2,500,000 or more in annual rent, you qualify for the full ₦500,000 deduction. This reduces your PAYE — at the 18% band, the full ₦500,000 saves you ₦90,000 per year. At the 25% band, it saves ₦125,000.

Why Most Employees Do Not Claim It

Your employer cannot apply rent relief without evidence. They need a tenancy agreement, rent receipts, and ideally bank transfer evidence showing you paid the rent. Most employees never provide these documents. Some do not know the deduction exists. Others know but do not bother with the paperwork. The result is that their employer computes PAYE without rent relief — and they overpay every month.

How to Fix This

1. Gather your tenancy agreement and rent receipts (or bank transfer confirmations)
2. Submit them to your HR or payroll department
3. Request that rent relief be applied to your PAYE computation
4. Verify on your next payslip that the deduction has been included

If you are mid-year, your employer can recalculate your annual PAYE to include the rent relief and adjust your monthly deductions for the remaining months. If you have already overpaid, the adjustment should bring your year-to-date PAYE back into line by reducing the deduction in the remaining months — effectively refunding the overpayment through lower future deductions.

Deduction 5: Life Insurance Premiums — Rarely Claimed by Employees

If you hold a qualifying life insurance policy with a registered Nigerian insurer, the premiums you pay are deductible from your chargeable income. This deduction is rarely claimed by employees because most do not hold personal life insurance policies (as distinct from group life insurance provided by the employer, which is an employer cost and not your deduction).

If you do hold a personal life insurance policy, submit the premium payment receipt or annual statement from the insurer to your HR department and request that it be included in your PAYE computation. The full premium amount is deductible — there is no cap under the NTA 2025.

The Cumulative Cost of Missing Deductions

These deductions do not exist in isolation. Most employees are entitled to pension, at least one of NHF or NHIS, and rent relief. When multiple deductions are misconfigured or unclaimed, the excess PAYE compounds.

Worked Example: What Missing Deductions Actually Cost

Aisha earns ₦10,000,000 gross per year. Her correct package breakdown:

Her correct deductions:

Now compare Aisha’s PAYE in two scenarios:

Aisha overpays ₦144,900 per year if NHF, NHIS, and rent relief are missing from her PAYE computation. She overpays ₦260,100 per year if all deductions are missing — including pension. Over a five-year period, the cumulative overpayment ranges from ₦724,500 to ₦1,300,500.

These are not unusual numbers. They are the routine cost of a misconfigured payroll system that millions of Nigerian employees are paying without knowing it.

How to Fix Your Payslip: A Step-by-Step Process

1. Download or request your payslip. Get the most recent version — ideally one that shows both the deduction lines and the PAYE computation breakdown.
2. Identify your pensionable base. Add Basic + Housing + Transport. Multiply by 8%. Compare to the pension deduction on the payslip. Flag any discrepancy.
3. Check NHF. Calculate 2.5% of your basic salary. Compare to the NHF line on the payslip. If NHF is not shown at all, confirm with HR whether your employer participates in the NHF scheme.
4. Check NHIS. Identify any health insurance deduction. Confirm whether it is an employee contribution (deductible) or employer-only (not your deduction). If it is your contribution, check that it reduces your taxable income in the PAYE computation.
5. Check rent relief. If you have not submitted rent documentation to HR, do it now. If you have, confirm that the relief (20% of rent, max ₦500,000) is included in the PAYE computation.
6. Verify PAYE. Use our PAYE Calculator to compute your correct annual PAYE based on your gross income minus all applicable deductions. Compare the calculator result to the PAYE shown on your payslip.
7. Raise discrepancies with HR. If the numbers do not match, write to your HR or payroll department identifying the specific error — “My pension is computed on gross salary instead of Basic + Housing + Transport” or “My NHIS contribution is not being deducted from taxable income before PAYE is computed.” Be specific. Attach your calculation.
8. Follow up. Check your next payslip to confirm the correction has been made. If the error has persisted for several months, request a reconciliation showing the cumulative overpayment and a plan to refund it (typically through reduced PAYE deductions in the remaining months of the year).

What If Your Employer Will Not Correct the Error?

If your employer acknowledges the error but does not correct it, or if they dispute your calculation, you have options:

• Escalate internally. Go above the payroll officer — to the finance manager, the HR director, or the managing director. A clear, written explanation with the correct figures is difficult to ignore.
• File your individual annual return with the correct figures. Under the NTAA 2025, every employee must file their own PIT return by 31 March. You can claim the correct deductions on your individual return even if your employer’s payroll did not apply them. If the result shows you overpaid PAYE, you can request a refund or credit from the State IRS.
• Engage a tax professional. A chartered accountant or tax practitioner can write to your employer on your behalf, referencing the specific NTA 2025 and PRA 2014 provisions. This often resolves the issue quickly. Find one through our Tax Professional Directory.
• Report to the State IRS. If all else fails, the State IRS can intervene — particularly if the employer is systematically over-deducting PAYE from employees by not applying mandatory deductions. This is a last resort but is available to you.

The Old CRA Is Gone — Do Not Let Anyone Apply It

Under the old PITA, the Consolidated Relief Allowance (CRA) — 20% of gross income plus ₦200,000 — was the primary personal deduction for employees. It was simple, automatic, and did not require documentation. The NTA 2025 abolished CRA entirely from the 2026 tax year onwards.

It has been replaced by the specific deductions covered in this guide: pension, NHF, NHIS, rent relief, and life insurance. These are documentation-dependent and computation-specific — which is why errors are more common now than under the old CRA system.

If your payslip still shows a CRA deduction, your employer’s payroll system has not been updated for the NTA 2025. Every PAYE figure it produces is wrong. Raise this immediately — it affects every employee in the organisation, not just you.

Final Thoughts

Pension, NHF, NHIS, rent relief, and life insurance are not optional extras — they are deductions the NTA 2025 specifically provides to reduce your chargeable income and your PAYE. But they only work if they are correctly applied in the PAYE computation, and the evidence shows that many payroll systems get them wrong. The pension base is wrong. NHF is deducted from salary but not from taxable income. NHIS contributions are ignored in the PAYE calculation. Rent relief is never claimed because the employee never submitted a receipt.

The fix starts with your payslip. Check it this month. Run the numbers. Compare them to our PAYE Calculator. If the figures do not match, you now know exactly where the error is and how to raise it. The difference could be ₦100,000 to ₦260,000 per year — money that is already yours under the law but is being collected in excess because of a configuration error that nobody checked.

FAQs About Employee Tax Deductions in Nigeria

What is the correct base for computing employee pension?

Basic Salary + Housing Allowance + Transport Allowance only. Not gross salary, not basic alone. The employee contributes 8% of this base. If your payslip shows pension computed on a different base, the deduction is wrong — and your PAYE may also be wrong. Verify the pensionable components on your payslip and raise any discrepancy with HR.

Is the NHF contribution tax-deductible?

Yes. NHF contributions (2.5% of basic salary) are deductible from chargeable income under the NTA 2025. They reduce your taxable income and your PAYE. However, the deduction only applies if your employer participates in the NHF scheme and actually remits the contributions to the Federal Mortgage Bank of Nigeria.

Can I claim my health insurance contribution as a tax deduction?

Yes — the employee portion. If you personally contribute towards your health insurance plan (NHIS or an employer-operated scheme), that contribution is deductible from your chargeable income. If the employer pays 100% and you contribute nothing, there is no deduction for you. Check your payslip to determine whether you have a personal health insurance contribution.

How do I claim rent relief if my employer has not applied it?

Submit your tenancy agreement, rent receipts, and bank transfer evidence to your HR or payroll department and request that rent relief (20% of annual rent, capped at ₦500,000) be included in your PAYE computation. If you are mid-year, the employer can recalculate and adjust your remaining monthly PAYE. If you have already overpaid, the correction should be reflected in reduced deductions for the remaining months.

What if my payslip still shows CRA?

The Consolidated Relief Allowance (20% of gross plus ₦200,000) was abolished by the NTA 2025 from the 2026 tax year. If your payslip still shows CRA, your payroll system has not been updated. Every PAYE figure it produces is incorrect. Raise this with HR immediately — it affects every employee in your organisation.

How much can I save by claiming all my deductions?

For an employee earning ₦10,000,000 gross, correctly applying pension, NHF, NHIS, and rent relief can reduce annual PAYE by ₦145,000 to ₦260,000 depending on which deductions were previously missing. Over five years, the cumulative saving ranges from ₦725,000 to ₦1,300,000. The higher your income and the more deductions that are missing, the larger the overpayment.

Can I claim these deductions on my own annual return even if my employer did not apply them?

Yes. Under the NTAA 2025, every employee must file their own individual PIT return by 31 March. You can claim pension, NHF, NHIS, rent relief, and life insurance deductions on your individual return with supporting documentation, even if your employer’s payroll did not apply them. If the result shows you overpaid PAYE, you can request a refund or credit from the State IRS.
