Payroll & PAYE Compliance in Nigeria: The Complete Guide for Employers and Practitioners

Every month, Nigerian employers are required to deduct Pay-As-You-Earn (PAYE) tax from employee salaries and remit it to the relevant state Internal Revenue Service (IRS). Every year, they must file an annual return reconciling all deductions. And every year, a staggering number of businesses get it wrong.

Late remittances. Incorrect computations. Missing employee records. Failure to register new hires. These aren't minor oversights: they carry penalties of up to 10% of the unremitted amount, plus interest on overdue payments. For firms managing payroll for multiple clients, the risk multiplies with every engagement.

This guide covers the complete PAYE compliance lifecycle: who's responsible, how to calculate correctly, when to file, and how to stop doing all of it in spreadsheets.

Who Is Responsible for PAYE?

PAYE is a withholding obligation that falls squarely on the employer. When an employee earns income from employment, the employer must:

1. Calculate the correct tax liability based on the employee's gross income and applicable reliefs.
2. Deduct the PAYE amount from the employee's salary before payment.
3. Remit the deducted amount to the appropriate state IRS by the 10th of the following month.
4. File an annual PAYE return by January 31st of the following year.

Important distinction: PAYE is administered by state governments, not the federal NRS. The relevant state IRS is determined by the employee's place of residence, not the employer's registered address. For businesses with employees across multiple states, this means multiple remittances to multiple authorities every month.

How PAYE Is Calculated

PAYE is calculated using the graduated tax table under the Personal Income Tax Act (as amended), after applying statutory reliefs:

Step 1: Determine Gross Income

Add all forms of employment income: basic salary, housing allowance, transport allowance, bonuses, overtime, benefits in kind, and any other taxable perquisites. Leave out only items specifically exempted by law, such as gratuities up to certain limits and employer pension contributions.

Step 2: Apply Statutory Reliefs

Every individual is entitled to:

• Consolidated Relief Allowance (CRA): ₦200,000 or 1% of gross income (whichever is higher), plus 20% of gross income.
• Pension contributions: Employee contributions to the National Pension Commission scheme (typically 8% of basic, housing, and transport allowances) are deductible.
• National Health Insurance (NHIS): Employee contributions to approved health insurance schemes.
• Life insurance premiums: Premiums on the employee's life, subject to conditions.
• National Housing Fund (NHF): 2.5% of basic salary contributed to the NHF.

Step 3: Apply the Graduated Tax Table

After deducting reliefs from gross income, the resulting taxable income is taxed in bands:

• 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%

Minimum tax rule: If the calculated tax is lower than 1% of gross income, the employee pays the higher of the two. This ensures every employee above a minimum threshold contributes something, even after reliefs.

Monthly Remittance: The 10th-of-the-Month Deadline

PAYE deductions for each month must be remitted to the state IRS by the 10th of the following month. This is non-negotiable and strictly enforced.

Each remittance must be accompanied by:

• A schedule of employees showing each person's name, TIN, gross income, reliefs, taxable income, and tax deducted for the period.
• Proof of payment (bank teller or electronic payment receipt).
• Any variation notices for new hires, terminations, or salary changes.

Late remittance penalties: A penalty of 10% of the unremitted tax is applied, plus interest at the prevailing Central Bank of Nigeria rate. These penalties are calculated from the due date, not from when the state IRS discovers the shortfall. They compound. They are painful.

Annual Returns: The January 31st Filing

By January 31st each year, every employer must file an annual PAYE return reconciling all monthly deductions for the preceding year. This return includes:

• A summary schedule showing total gross emoluments, total reliefs, total taxable income, and total PAYE deducted across all employees.
• Individual employee schedules with the full annual computation for each staff member.
• Reconciliation of total PAYE deducted against total amounts remitted, including references to all payment receipts.
• A list of employees who joined or left during the year, with their start or end dates and final settlement details.

The reconciliation is where most firms get caught. If the total deducted doesn't match the total remitted, the state IRS will demand the difference plus penalties. For firms managing payroll for dozens of clients, reconciling twelve months of spreadsheets against bank payment records is a significant and error-prone exercise.

The Most Common PAYE Compliance Failures

1. Using outdated relief calculations. The CRA formula changed with the 2020 Finance Act amendments. Firms still using the old consolidated allowance structure are under-deducting or over-deducting, both of which create problems during annual reconciliation.
2. Failing to register new employees. Every new hire must be registered with the relevant state IRS and included in the monthly schedule. Omitting staff from the schedule doesn't reduce the employer's liability — it just defers it with penalties.
3. Misclassifying benefits in kind. Company cars, housing provided by the employer, staff loans at below-market rates — these all have taxable values that must be included in gross income computations. Ignoring them is a common audit finding.
4. Filing to the wrong state. PAYE is remitted to the state where the employee resides, not where the company is registered. A Lagos-registered company with staff living in Ogun State must remit those employees' PAYE to Ogun State IRS. This is frequently overlooked.
5. Not issuing tax deduction cards. Employers are required to issue annual tax deduction cards to employees showing the total tax deducted during the year. Many firms don't bother, which creates problems when employees need to file personal returns or claim WHT credits.
6. Manual calculation errors. With graduated rates, multiple reliefs, and monthly variations in bonuses and allowances, spreadsheet-based PAYE calculations are highly susceptible to formula errors. A single wrong cell reference can cascade across hundreds of employee records.

Special Situations That Complicate PAYE

• Mid-year hires and terminations: Pro-rating annual reliefs for employees who join or leave mid-year is essential but frequently done incorrectly. The CRA must be pro-rated based on actual months of employment, not applied in full.
• Bonus and 13th-month payments: These are fully taxable and must be included in the month's PAYE computation. Treating them as "separate" from regular salary to avoid higher tax bands is non-compliant.
• Expatriate employees: Foreign nationals working in Nigeria are subject to Nigerian PAYE on their Nigerian-source employment income. Their gross income calculations may also include housing, school fees, and home-leave passage provided by the employer.
• Multi-state workforces: Companies with employees across multiple states must maintain separate schedules and remittance records for each state IRS, significantly increasing administrative complexity.

How Technology Eliminates Payroll Compliance Risk

Manual payroll processing doesn't scale. Once a business exceeds a dozen employees, or a firm manages PAYE for more than a handful of clients, the spreadsheet model breaks down. Every additional employee, every salary change, and every new state adds complexity that multiplies the risk of error.

EzeeTax automates the entire PAYE workflow:

• Automatic PAYE computation using the current graduated tax table and all applicable reliefs, updated whenever legislation changes.
• Monthly schedules generated automatically with all employee details, deductions, and remittance totals ready for submission.
• Multi-state handling that separates employees by their state of residence and generates state-specific remittance schedules.
• Annual reconciliation at the click of a button, matching twelve months of deductions against remittance records and highlighting any discrepancies instantly.
• Deadline alerts that notify your team before the 10th of each month and the January 31st annual filing deadline, so nothing slips through.
• Tax deduction card generation for every employee, ready for distribution at year-end.

Payroll compliance isn't complicated because the rules are unclear. It's complicated because applying them consistently across dozens of employees, twelve months a year, without automation, is humanly unreliable.

PAYE compliance is a monthly obligation with annual consequences. The firms and employers that automate it sleep well every month. The ones that don't spend every January scrambling through spreadsheets, hoping the numbers add up. They usually don't.
