Running payroll for a Nigerian company means managing multiple statutory deductions. PAYE tax, PenCom pension, NHIS, NSITF, and housing fund all need accurate calculation and timely remittance. Get any wrong, and you face penalties, audits, and employee distrust.
A custom payroll system removes the guesswork. You automate every deduction, generate compliant payslips, and stay on top of filing deadlines. This guide covers what your payroll software needs for full Nigerian statutory compliance.
| Deduction | Employee | Employer | Regulator | Deadline |
|---|---|---|---|---|
| PAYE Tax | 7-24% | N/A | FIRS / State IRS | 10th next month |
| Pension | 10% | 10% | PenCom | 7th next month |
| NHIS | 2.5% | 2.5% | NHIS / HMO | Monthly |
| NSITF | 1% | 1% | NSITF | Monthly |
| Housing Fund | 2.5% | N/A | Fed. Mortgage Bank | Monthly |
Building PAYE Tax Calculation Into Your Payroll System
PAYE is the most complex statutory calculation in Nigerian payroll. The tax follows a graduated table with six bands. Your system needs to apply the Consolidated Relief Allowance (CRA) of NGN 200,000 plus 20% of gross income before computing tax on the remaining amount.
Different states in Nigeria have their own IRS agencies. Your payroll software must support multi-state tax filing if you have employees across Lagos, Abuja, Rivers, and other states. Each state may request slightly different reporting formats.
Monthly remittance to FIRS or the relevant State IRS must happen by the 10th of the following month. Your software should generate the exact remittance schedule and flag any missed deadlines. Annual PAYE reconciliation returns add another layer that your system must handle.
Tax bands for 2026 start with the first NGN 300,000 exempt from tax. Income from NGN 300,001 to NGN 600,000 is taxed at 7%. Rates increase through 11%, 15%, 19%, and 21%, reaching 24% above NGN 3,200,000. Your system must apply these bands correctly.
PenCom Pension Contribution Management
The Pension Reform Act requires every employer with three or more employees to maintain a pension scheme. Your payroll software must calculate 10% employee contribution and 10% employer contribution based on the employee's monthly emolument.
Each employee has a Retirement Savings Account (RSA) with a Pension Fund Administrator (PFA) of their choice. Your system needs to map employees to their PFAs and generate contribution schedules per PFA in PenCom-approved format.
PenCom penalties for late remittance include interest at 2% above the CBN minimum rediscount rate. Your payroll system should enforce strict remittance timelines to protect your business from these charges.
New employees must complete RSA registration within seven days of resumption. The system should track this and flag unregistered employees. Contribution remittance should happen alongside salary payments.
NHIS, NSITF, and Housing Fund Deductions
The National Health Insurance Scheme requires 2.5% from both employer and employee. Your system must compute this on basic salary and remit to the NHIS or your preferred HMO. Many Nigerian companies now offer private HMO options instead of the public scheme.
NSITF under the Employees' Compensation Act requires 1% contribution from both parties. This covers employees against workplace injuries or death. Your payroll system should track this deduction and generate the NSITF schedule.
National Housing Fund contributions of 2.5% of basic salary apply to employees earning NGN 3,000 or more per annum. These funds go to the Federal Mortgage Bank of Nigeria. Your system must flag eligible employees and exclude exempt categories.
Payslip Generation and Compliance Calendar
Every Nigerian employee is entitled to a payslip showing gross pay, all deductions, net pay, and employer contributions. Your payroll software should generate professional payslips that employees can access digitally through a self-service portal. Include year-to-date totals for tax purposes.
A compliance calendar within your system tracks every remittance deadline across all five statutory bodies. Automated reminders ensure you never miss a filing date. The system should also produce audit-ready reports for each regulator.
Integrating payroll with your HR system creates a single source of truth for employee data. New hires, terminations, salary changes, and promotions flow automatically into the payroll module, reducing errors and ensuring compliance from day one.
Digital payslip delivery reduces paper costs and speeds up distribution. Employees can access past payslips anytime, reducing HR queries. The system should support bulk email or SMS delivery for teams without regular computer access.
