How to Calculate PAYE Tax on Your Nigerian Salary — Complete Guide

The Money Leaving Your Pay Slip Every Month

Every Nigerian employee who has ever collected a pay slip has seen it.

A line item somewhere between your gross salary and your net take-home that simply says PAYE — followed by a figure that reduces what actually enters your bank account.

For most Nigerian workers, this deduction is a mystery. They know it is tax. They know their employer takes it. But they have no idea how it is calculated, whether the amount is correct, whether their employer is actually remitting it to the government, or whether they are paying more than they legally should.

This ignorance is expensive.

Every year, thousands of Nigerian employees overpay PAYE because their employers miscalculate the deduction — and because the employees themselves have no way to verify the calculation. Some employers deduct PAYE correctly but fail to remit it to the relevant State Internal Revenue Service — meaning the employee’s tax record shows non-compliance through no fault of their own. And some employees miss legitimate deductions that would reduce their PAYE liability if they knew to claim them.

This guide gives you the complete, practical understanding of how PAYE is calculated in Nigeria — with real numbers, worked examples at different salary levels, and the exact knowledge you need to verify that what your employer deducts is what the law actually requires.

What PAYE Is and Why It Exists

Pay As You Earn (PAYE) is the system by which Personal Income Tax is deducted from employee salaries at source — meaning your employer deducts the tax from your pay before you receive it and remits it directly to the relevant tax authority.

PAYE is governed by the Personal Income Tax Act (PITA) as amended, most recently by the Finance Acts of 2019, 2020, and 2021. For employees, PAYE is the primary mechanism through which they fulfil their Personal Income Tax obligations — which means that if your employer is deducting and remitting PAYE correctly, your income tax obligations are being met automatically without any action required from you.

Who administers PAYE in Nigeria:

PAYE is administered by State Internal Revenue Services (SIRS) — not FIRS. Your state of residence (not your employer’s state, not your state of origin — your state of residence) determines which SIRS receives your PAYE remittance. Lagos State employees’ PAYE goes to Lagos State Internal Revenue Service (LIRS). Abuja employees’ PAYE goes to FCT Internal Revenue Service. And so on.

Who must deduct PAYE:

Every employer in Nigeria is legally required to deduct PAYE from the salaries of all employees and remit the deductions to the relevant SIRS by the 10th of the following month. This obligation exists regardless of whether the employer is a large corporation or a small registered business.

The Building Blocks of PAYE Calculation

Before walking through the calculation step by step, you need to understand four key concepts:

Gross Income

Your gross income for PAYE purposes includes everything your employment pays you — not just your basic salary. This includes:

• Basic salary
• Housing allowance
• Transport allowance
• Meal allowance
• Leave allowance
• Utility allowance
• Entertainment allowance
• Medical allowance (if paid as cash rather than benefit-in-kind)
• Any other regular cash payments from your employer

What is excluded from gross income:

• Non-cash benefits such as official accommodation (provided directly, not as cash allowance)
• Reimbursements for actual business expenses
• Pension contributions made by your employer (employer’s own contribution)

Consolidated Relief Allowance (CRA)

The Consolidated Relief Allowance is the primary tax relief available to all Nigerian employees. It reduces your taxable income before tax rates are applied. The CRA is calculated as:

CRA = Higher of (₦200,000 OR 1% of Gross Income) PLUS 20% of Gross Income

In practice for most Nigerian salary earners:

• If your annual gross income is below ₦20,000,000, the ₦200,000 component is higher than 1% of gross income
• The 20% of gross income component is the larger and more impactful part

Example: Annual gross income of ₦3,000,000

• 1% of ₦3,000,000 = ₦30,000 (less than ₦200,000, so use ₦200,000)
• 20% of ₦3,000,000 = ₦600,000
• Total CRA = ₦200,000 + ₦600,000 = ₦800,000

Other Allowable Deductions

Beyond the CRA, these specific contributions are deductible from gross income before calculating your taxable income:

Pension Contribution (Employee’s Share): Under the Contributory Pension Scheme, employees contribute a minimum of 8% of monthly emolument (basic salary + housing allowance + transport allowance). This 8% employee contribution is fully deductible for PAYE purposes.

National Housing Fund (NHF): Employees in the public sector and eligible private sector employees contribute 2.5% of basic salary monthly to the Federal Mortgage Bank of Nigeria through the NHF scheme. This contribution is deductible.

National Health Insurance Scheme (NHIS): Employee NHIS contributions are deductible.

Life Assurance Premiums: Premiums paid on qualifying life assurance policies are deductible, subject to certain conditions.

Tax Bands (Graduated Tax Rates)

Once your taxable income is determined (Gross Income minus CRA minus allowable deductions), it is taxed at graduated rates:

Taxable Income Band	Tax 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%

The Step-by-Step PAYE Calculation Formula

Step 1: Calculate Annual Gross Income (add up all annual employment income)

Step 2: Calculate the Consolidated Relief Allowance — (Higher of ₦200,000 or 1% of gross) + 20% of gross

Step 3: Calculate other allowable deductions (pension, NHF, NHIS, life assurance)

Step 4: Calculate Taxable Income — Gross Income minus CRA minus other deductions

Step 5: Apply the graduated tax bands to the taxable income

Step 6: Total annual tax divided by 12 gives monthly PAYE deduction

Worked Examples at Different Salary Levels

Example One: Monthly Gross Salary of ₦100,000 (Annual ₦1,200,000)

Step 1: Annual Gross Income ₦100,000 × 12 = ₦1,200,000

Step 2: Consolidated Relief Allowance

• 1% of ₦1,200,000 = ₦12,000 (less than ₦200,000, use ₦200,000)
• 20% of ₦1,200,000 = ₦240,000
• Total CRA = ₦200,000 + ₦240,000 = ₦440,000

Step 3: Other Allowable Deductions

• Pension (8% of emolument): Assuming basic = ₦60,000/month, annual basic = ₦720,000
• 8% pension = ₦57,600
• NHF (2.5% of basic): ₦720,000 × 2.5% = ₦18,000
• Total other deductions = ₦75,600

Step 4: Taxable Income ₦1,200,000 − ₦440,000 − ₦75,600 = ₦684,400

Step 5: Apply Tax Bands

• First ₦300,000 at 7% = ₦21,000
• Next ₦300,000 at 11% = ₦33,000
• Remaining ₦84,400 at 15% = ₦12,660
• Total Annual Tax = ₦66,660

Step 6: Monthly PAYE ₦66,660 ÷ 12 = ₦5,555 per month

Example Two: Monthly Gross Salary of ₦200,000 (Annual ₦2,400,000)

Step 1: Annual Gross Income ₦200,000 × 12 = ₦2,400,000

Step 2: Consolidated Relief Allowance

• 1% of ₦2,400,000 = ₦24,000 (less than ₦200,000, use ₦200,000)
• 20% of ₦2,400,000 = ₦480,000
• Total CRA = ₦680,000

Step 3: Other Allowable Deductions

• Pension (8%): Assuming monthly emolument = ₦150,000, annual = ₦1,800,000
• 8% pension = ₦144,000
• NHF (2.5% of basic, assuming basic ₦120,000/month): ₦1,440,000 × 2.5% = ₦36,000
• Total other deductions = ₦180,000

Step 4: Taxable Income ₦2,400,000 − ₦680,000 − ₦180,000 = ₦1,540,000

Step 5: Apply Tax Bands

• First ₦300,000 at 7% = ₦21,000
• Next ₦300,000 at 11% = ₦33,000
• Next ₦500,000 at 15% = ₦75,000
• Remaining ₦440,000 at 19% = ₦83,600
• Total Annual Tax = ₦212,600

Step 6: Monthly PAYE ₦212,600 ÷ 12 = ₦17,717 per month

Example Three: Monthly Gross Salary of ₦500,000 (Annual ₦6,000,000)

Step 1: Annual Gross Income ₦500,000 × 12 = ₦6,000,000

Step 2: Consolidated Relief Allowance

• 1% of ₦6,000,000 = ₦60,000 (less than ₦200,000, use ₦200,000)
• 20% of ₦6,000,000 = ₦1,200,000
• Total CRA = ₦1,400,000

Step 3: Other Allowable Deductions

• Pension (8%): Assuming emolument ₦380,000/month, annual ₦4,560,000
• 8% pension = ₦364,800
• NHF: ₦300,000 basic/month × 12 × 2.5% = ₦90,000
• Total other deductions = ₦454,800

Step 4: Taxable Income ₦6,000,000 − ₦1,400,000 − ₦454,800 = ₦4,145,200

Step 5: Apply Tax Bands

• First ₦300,000 at 7% = ₦21,000
• Next ₦300,000 at 11% = ₦33,000
• Next ₦500,000 at 15% = ₦75,000
• Next ₦500,000 at 19% = ₦95,000
• Next ₦1,600,000 at 21% = ₦336,000
• Remaining ₦945,200 at 24% = ₦226,848
• Total Annual Tax = ₦786,848

Step 6: Monthly PAYE ₦786,848 ÷ 12 = ₦65,571 per month

The Minimum Tax Rule — When It Applies

There is a minimum tax provision in Nigeria’s tax law that ensures every income earner pays something regardless of how large their deductions are.

Minimum Tax = 1% of Gross Income

If the tax calculated through the normal graduated rate process produces a lower figure than 1% of gross income, the taxpayer pays the higher amount — which in this case would be the minimum tax.

When does minimum tax typically apply?

For very low income earners whose gross income barely exceeds their deductions, the graduated rate calculation might produce a very small or even zero tax figure. The minimum tax ensures they still pay at least 1% of gross income.

Important exemption: Employees earning the minimum wage (currently ₦70,000 per month) or below are exempt from minimum tax entirely under amendments introduced in the Finance Act 2019.

How to Verify Your Employer’s PAYE Deduction

Now that you understand how PAYE is calculated, here is how to verify that what appears on your pay slip is correct:

Step 1: Obtain your complete annual salary structure from your HR department — the full breakdown of every allowance and benefit you receive and how they are classified.

Step 2: Calculate your annual gross income by adding all annual employment income components.

Step 3: Apply the CRA formula to determine your relief allowance.

Step 4: Identify and calculate all allowable deductions — your pension contribution rate, NHF if applicable, NHIS contributions.

Step 5: Subtract CRA and other deductions from gross income to get taxable income.

Step 6: Apply the graduated tax bands to calculate annual tax liability.

Step 7: Divide by 12 to get the monthly figure and compare to what appears on your pay slip.

A discrepancy of more than a few thousand naira warrants a discussion with your payroll or HR department for explanation.

What to Do If Your Employer Is Not Remitting Your PAYE

This is a more serious issue than many Nigerian employees realise. An employer who deducts PAYE from employees but fails to remit it to the State Internal Revenue Service has:

• Committed a criminal offence under PITA
• Potentially damaged the employees’ personal tax compliance records
• Exposed the company to significant penalties, interest, and potential prosecution

Signs your employer may not be remitting:

• You cannot obtain a PAYE receipt or tax clearance certificate from your state revenue service
• Your employer is consistently late with salary payments (often a sign of general financial distress that extends to PAYE)
• Your HR department cannot produce PAYE payment evidence when asked

What you can do:

• Write a formal internal request to your HR or Finance department for a PAYE remittance schedule showing the amounts deducted and the dates remitted
• Contact your State Internal Revenue Service directly to request a statement of your tax account — they can tell you what has been remitted on your behalf
• If non-remittance is confirmed, document everything and consider reporting to the SIRS — the law protects employees who report employer non-compliance

Frequently Asked Questions About PAYE in Nigeria

Is PAYE deducted on bonuses and 13th month salary? Yes. Bonuses, 13th month salary, and other irregular payments are part of your gross income for PAYE purposes. Your employer should include these in your annual PAYE calculation.

What if I work for two employers simultaneously? You must declare both sources of income to your SIRS and file a self-assessment return to reconcile your total PAYE liability across both employers.

What happens if I leave a job midway through the year? Your former employer should issue you a tax deduction card (Form H1) showing the total PAYE deducted during your period of employment. Present this to your new employer so they can calculate the balance of your annual PAYE obligation correctly.

Is PAYE the same as the tax filed in annual returns? For most employees, PAYE covers your entire income tax obligation. However, if you have income from other sources beyond employment — such as rental income, business profits, or investment income — you are required to file an annual self-assessment return declaring all sources.

Can I claim a tax refund if too much PAYE was deducted? Yes. If your employer deducted more PAYE than your actual liability — for example, if they did not apply your pension deduction correctly — you can file a claim for refund with your SIRS. Keep all pay slips and deduction records to support such a claim.

PAYE Knowledge Is Financial Power

Most Nigerian employees are passive participants in their own tax affairs — they see the PAYE line on their pay slip, shrug, and accept whatever figure appears without question.

This guide gives you the tools to be different.

When you understand how PAYE is calculated, you can:

• Verify that your employer’s deduction is accurate
• Identify if allowable deductions are being missed
• Understand the real after-tax value of a job offer before accepting it
• Confirm that your employer is actually remitting your taxes — not pocketing them
• Make informed decisions about additional income and its tax implications

Understanding your PAYE does not require an accounting degree. It requires the formula, the tax bands, and the willingness to spend thirty minutes doing the calculation with your own numbers.

You now have all three.
