Employer Payroll Compliance in Nigeria: Complete Guide to FIRS, State IRS, PenCom, and NSITF

April 16, 2026
Nigeria's payroll compliance framework is uniquely complex for one reason that catches nearly every international operator off guard: PAYE is a state tax, not a federal one. While the Federal Inland Revenue Service (FIRS) governs corporate income tax, each of Nigeria's 36 states — plus the FCT — operates its own Internal Revenue Service, sets its own filing procedures, and enforces its own penalties. An employer with employees in Lagos, Abuja, and Port Harcourt is managing three separate tax authorities simultaneously.
Layered on top of the multi-state PAYE structure are four federal obligations: pension contributions under PenCom, employee compensation contributions to NSITF, the National Housing Fund (NHF) deduction, and the Industrial Training Fund (ITF) levy. Each has its own remittance channel and deadline.
Nigerian Payroll Authorities at a Glance
| Authority | Obligation | Level |
|---|---|---|
| State Internal Revenue Services (e.g. LIRS, FCTA-IRS) | PAYE withholding and remittance | State |
| Federal Inland Revenue Service (FIRS) | Annual income tax returns for individuals; employer filings | Federal |
| National Pension Commission (PenCom) | Pension contributions via licensed PFAs | Federal |
| Nigeria Social Insurance Trust Fund (NSITF) | Employee compensation contributions | Federal |
| Federal Mortgage Bank of Nigeria (FMBN) | National Housing Fund (NHF) deductions | Federal |
| Industrial Training Fund (ITF) | Annual training levy on qualifying employers | Federal |
PAYE — The Multi-State Challenge
How jurisdiction is determined
An employee's PAYE is remitted to the state where they are resident — not where the employer is incorporated, and not where the employee works if that differs from where they live. Residency is determined by where the employee has their "usual place of abode." For remote workers, this means contributions follow the employee's home state, regardless of where the employer's office is.
An employer headquartered in Lagos with remote employees in Kano, Enugu, and Rivers State must register with and remit to four separate state IRSs. Each has its own employer registration process, payment portal, and filing schedule.
PAYE tax bands (Personal Income Tax Act, as amended)
| Annual taxable income | Rate |
|---|---|
| First ₦300,000 | 7% |
| Next ₦300,000 | 11% |
| Next ₦500,000 | 15% |
| Next ₦500,000 | 19% |
| Next ₦1,600,000 | 21% |
| Above ₦3,200,000 | 24% |
These bands are set by the Personal Income Tax Act (PITA) Cap P8 LFN 2011, as amended by the Finance Acts. Verify whether the Finance Act 2024 introduced any amendments before filing.
Allowable deductions before tax
Nigerian PITA allows several deductions from gross income before applying the tax bands:
- Consolidated Relief Allowance (CRA): The higher of ₦200,000 or 1% of gross income, plus 20% of gross income. This is the most significant deduction — for most employees it removes a substantial portion of gross from the taxable base.
- Pension contributions: The employee's 8% contribution to their Retirement Savings Account (RSA) is deductible.
- NHF contributions: The employee's 2.5% NHF deduction is deductible.
- Life assurance premiums and National Housing Fund contributions are also deductible where applicable.
The CRA structure means Nigerian effective tax rates are substantially lower than the headline bands suggest. An employee earning ₦5,000,000/year will have roughly ₦1,200,000+ stripped from the taxable base before the bands apply.
Minimum tax
Where the computed PAYE liability is lower than 1% of gross income, a minimum tax of 1% of gross income applies. This catches low-earning employees who would otherwise owe negligible tax after relief.
Remittance deadlines
PAYE must be remitted to the relevant state IRS by the 10th of the following month. Most states now have electronic payment portals — Lagos (LIRS), FCT (FCTA-IRS), and Rivers are the most developed. Some smaller state IRSs still require manual bank drafts and physical filing; verify the current process for each state where you have employees.
Annual employer returns (Form H1 in most states) declaring total PAYE withheld for all employees must be filed by 31 January of the following year.
Pension Contributions (PenCom)
Nigeria's contributory pension scheme is governed by the Pension Reform Act 2014 and regulated by the National Pension Commission (PenCom). It applies to all employers with three or more employees.
Rates
| Party | Rate | Base |
|---|---|---|
| Employee | 8% | Monthly emoluments |
| Employer | 10% | Monthly emoluments |
| Total | 18% |
"Monthly emoluments" means basic salary plus housing allowance plus transport allowance — not total gross. Allowances that are performance-based or irregular (bonuses, overtime) are excluded from the pension base unless they form part of the contractual recurring package.
The employer minimum is 10% — employers may contribute more as a benefit.
Retirement Savings Accounts (RSAs)
Each employee must have an RSA with a licensed Pension Fund Administrator (PFA) of their choice. The employer contributes to whichever PFA the employee selects. Employers cannot dictate PFA choice. If a new employee does not provide their RSA PIN within 30 days, the employer should remit contributions to a suspense account with PenCom and reconcile once the employee enrols.
Remittance deadline
Pension contributions must be remitted within 7 working days of salary payment — the tightest deadline in the Nigerian payroll calendar. Late remittance attracts a penalty of 2% of the total contribution due per month of default, plus potential personal liability for company directors under the PRA 2014.
NSITF — Employee Compensation
The Nigeria Social Insurance Trust Fund (NSITF) provides compensation for work-related injuries, disabilities, and death. Contributions are employer-only — no employee deduction.
| Party | Rate | Base |
|---|---|---|
| Employer | 1% | Total monthly payroll |
| Employee | Nil | — |
The 1% applies to total payroll — all employees, all salaries — with no ceiling. Registration with NSITF and obtaining a compliance certificate is also required for many government contracts and regulatory approvals. Non-compliance is a common disqualifier in public sector procurement.
Remittance deadline: Monthly, by the last working day of the following month. Annual compliance certificates are issued upon up-to-date payment status.
National Housing Fund (NHF)
The NHF is a mandatory deduction for Nigerian employees earning ₦3,000/month or above — in practice, every formal sector employee. It is employer-administered but employee-funded.
| Party | Rate | Base |
|---|---|---|
| Employee | 2.5% | Basic salary only |
| Employer | Nil | — |
The employer deducts 2.5% of the employee's basic salary and remits to the Federal Mortgage Bank of Nigeria (FMBN). The NHF deduction is also tax-deductible for the employee (reduces PAYE base). Employees who contribute for a qualifying period become eligible for FMBN mortgage loans.
Remittance deadline: Monthly, by the last working day of the month.
ITF Levy
The Industrial Training Fund levy applies to employers with five or more employees, or an annual turnover of ₦50 million or more.
| Rate | Base |
|---|---|
| 1% | Annual total payroll |
The ITF levy is an annual obligation, not monthly. It is assessed and remitted once per year to the ITF, with a return filed by 31 March covering the prior year's payroll. Employers who run qualifying training programmes can apply for partial reimbursement from the ITF, recovering up to 50% of the levy paid.
Total Employer Cost Summary
For a standard employee in Lagos (most common jurisdiction for international operators):
| Obligation | Employer rate |
|---|---|
| PAYE | Passthrough (withheld from employee) |
| Pension | 10% of monthly emoluments |
| NSITF | 1% of gross payroll |
| NHF | Passthrough (withheld from employee) |
| ITF | 1% of annual payroll (annualised: ~1%/12 per month) |
| Approximate total employer on-cost | ~11–11.1% |
Nigeria's employer contribution burden is lower than most African peers in percentage terms — the major compliance complexity is procedural (multi-state PAYE, 7-working-day pension deadline) rather than cost-driven.
Consolidated Compliance Calendar
| Deadline | Obligation |
|---|---|
| 7 working days after salary | Pension contributions to employee PFAs |
| 10th of following month | PAYE remittance to each relevant state IRS |
| Last working day of month | NHF deductions to FMBN |
| Last working day of following month | NSITF contributions |
| 31 January | Annual employer PAYE return (Form H1) to each state IRS |
| 31 March | ITF annual levy return and payment |
Penalties
| Obligation | Penalty |
|---|---|
| PAYE (late remittance) | 10% of tax due + 10% per annum interest |
| PAYE (late annual return) | ₦500,000 for first offence; ₦200,000 per month continuing |
| Pension (late remittance) | 2% of contribution due per month |
| NSITF (non-compliance) | Loss of compliance certificate; fines under ECA 2010 |
| NHF (non-deduction) | Fine up to ₦50,000 and/or 6 months imprisonment under NHF Act |
| ITF (non-payment) | 5% per annum surcharge plus enforcement action |
The pension penalty (2% per month compounding) is the most financially severe for payroll operations at scale. Missing the 7-working-day window — easy to do when payroll runs late — quickly generates meaningful liability.
Common Mistakes
1. Registering only with the Lagos IRS. Most international operators set up in Lagos and assume one state registration covers their Nigerian workforce. Any employee residing outside Lagos requires a separate registration with their state IRS. For remote-first employers, this can mean registrations across 10+ states.
2. Using gross salary as the pension base. Pension contributions apply to monthly emoluments — basic salary, housing, and transport — not total gross. Including performance bonuses, 13th-month payments, or irregular allowances inflates the pension base and overstates contributions.
3. Missing the 7-working-day pension window. The PenCom deadline runs from the date salary is paid, not from month-end. An employer who pays salaries on the 25th must remit pension by approximately the 4th or 5th of the following month — well before the PAYE deadline on the 10th. Operations teams that batch all payroll remittances on the 9th are systematically late on pension.
4. Not obtaining NSITF compliance certificates. Beyond the monthly contribution, employers need an active NSITF compliance certificate for government tenders, banking relationships, and regulatory approvals. Platforms whose clients include public-sector-adjacent businesses have found lapsed certificates a commercial blocker.
5. Applying PAYE bands without the CRA deduction. The Consolidated Relief Allowance is substantial and mandatory — not an optional employee election. Payroll engines that apply the PITA bands to gross income without netting the CRA systematically overwithhold tax and create reconciliation liabilities.
2027 Outlook
Finance Act amendments: Nigeria passes a Finance Act almost annually, frequently adjusting PITA provisions, PAYE administration, and employer obligations. The Finance Act 2024 made several changes to personal income tax administration — verify the current version before filing 2026 returns.
PenCom rate review: PenCom has signalled interest in increasing the minimum employer contribution above 10% as part of a broader pension adequacy review. Monitor PenCom circulars for any rate change effective 2027.
State IRS digitalisation: Lagos (LIRS) and the FCT IRS have the most developed electronic filing infrastructure. Several other states are in active digitalisation programmes — expect expanded e-filing options across more states by 2027, reducing the manual processing burden for multi-state employers.
ITF threshold review: The ₦50 million turnover threshold for ITF applicability has not been revised in years despite inflation. A threshold revision would bring more smaller employers into scope.
