What this Nigerian tax calculator does

This Nigerian tax calculator helps you estimate your PAYE (Pay As You Earn) for salary income in Nigeria. It is designed for workers who want a quick view of annual and monthly tax deductions, including pension, NHF, and other allowable deductions. If you are comparing job offers, planning your net salary, or simply checking your payslip, this tool gives you a practical starting point.

You can enter either monthly gross pay or annual gross pay. The calculator converts everything to annual values, applies reliefs and deductions, then computes tax using Nigeria’s progressive tax bands. The final output shows your estimated annual PAYE, monthly PAYE, and net income after tax and deductions.

How PAYE tax works in Nigeria (simple version)

1) Start from your gross income

Gross income is your total earnings before tax. In payroll settings, this usually includes your salary and any taxable allowances.

2) Subtract approved reliefs and deductions

Nigeria uses a Consolidated Relief Allowance (CRA) for personal income tax computations. A common formula is:

• Higher of ₦200,000 or 1% of gross income, then
• Add 20% of gross income.

After CRA, allowable deductions such as pension contributions, NHF contributions, life assurance premiums, and any other permitted deductions can reduce taxable income further.

3) Apply progressive tax bands

For annual taxable income, this calculator uses these PAYE brackets:

• First ₦300,000 at 7%
• Next ₦300,000 at 11%
• Next ₦500,000 at 15%
• Next ₦500,000 at 19%
• Next ₦1,600,000 at 21%
• Above ₦3,200,000 at 24%

How to use this calculator effectively

1. Select whether your input is monthly or annual gross income.
2. Enter your gross income amount in naira.
3. Confirm pension and NHF rates from your payslip or HR policy.
4. Add annual life assurance and other allowable deductions (if any).
5. Click Calculate Tax to view tax and net income breakdown.

Worked example (quick intuition)

Suppose your annual gross income is ₦6,000,000, pension is 8%, and NHF is 2.5%, with no additional deductions. The calculator first computes CRA, subtracts pension/NHF, then taxes only the remaining taxable income through the progressive tax bands. You will see both annual and monthly figures so you can compare against your payslip.

Why your final payroll may differ slightly

Real-world payroll can vary because of:

• Taxable vs non-taxable allowances treatment by employer payroll systems
• State-level interpretation and payroll implementation details
• Mid-year salary changes, bonuses, or arrears
• Rounding rules in payroll software

Treat this as an educational and planning tool. For compliance-grade calculations, use your organization’s payroll records or consult a licensed tax professional.
