Payroll Process Explained: How Businesses Handle Employee Salaries

The payroll process for businesses starts exactly like this. You’ve hired your employees, agreed on salaries, and felt good about it. Then, payday comes, and the questions pop up. How much should you deduct? Where does the tax go? What exactly is a pension remittance, and when do you need to pay it?

The good news is that the payroll process for businesses in Nigeria is not complicated once you know the basics. It follows a clear set of steps, a specific set of deductions, and deadlines that are easy to manage once you’re familiar with them.

This guide walks you through the full payroll process for businesses: what it includes, how each step works, who handles what, and how to make sure salaries are processed accurately every single month.

What Is the Payroll Process?

At its core, the payroll process for businesses is the set of steps involved in paying employees accurately and on time, every pay period. It starts with collecting employee data at the beginning of the cycle and ends with filing remittance receipts after payments go out.

In Nigeria, payroll is more than paying salaries. Each pay cycle, your business should calculate and deduct  PAYE, send it to the relevant State Internal Revenue Service by the 10th of the next month, deduct employee pension contributions and send them to the Pension Fund Administrator within seven working days after paying salaries, and handle contributions to NSITF, NHF, and NHIS where applicable.

Who handles payroll depends on your business size. In small businesses, one person in HR or finance usually manages everything. In larger organisations, HR handles employee data, finance handles calculations and payments, and a payroll administrator keeps the process on track. Some businesses choose to outsource payroll, especially when compliance becomes too complex for the internal team.

Key Steps in the Payroll Process

Now that you know what payroll involves, here is how the payroll process steps actually run.

Step 1: Collect your employee data

Before you start with the numbers, gather all your information in one place. This includes who worked, how many hours, any approved overtime, new hires, exits, and salary changes for the period. It’s like prepping before you cook. If anything is missing here, it will affect everything that comes after.

Step 2: Calculate salaries and deductions

This is where you do the calculations. Start with each employee’s gross salary, then work through the deductions: PAYE using the current 2026 tax bands, employee pension at 8% of basic, housing and transport allowance, and any other required contributions. What remains after deductions is the net pay, which is the actual amount that goes into the employee’s account.

Step 3: Review payroll calculations

Calculate the numbers, then ask someone else to review them. Compare this month’s results to last month’s and look into any changes that don’t have an approved reason. This step helps catch most mistakes before they turn into complaints.

Step 4: Pay your team and file your remittances.

Once everything is approved, send out the salaries. At the same time, take care of your remittance obligations: PAYE goes to your State Internal Revenue Service by the 10th, pension to the employee’s PFA within seven working days, and other required payments to their agencies.

Step 5: File and store your records

Each cycle should end with documentation, such as payslips, remittance receipts, and a reconciliation report. Keep these records for at least six years. You might not need them until an audit, but you’ll be glad you have them when it happens.

Common Challenges in Payroll Processing

Employee payroll processing is usually straightforward when things run smoothly. But as a business grows, issues tend to pop up more often.

1. Calculation errors: The more variables involved, allowances, bonuses, overtime, multiple pay structures, the more chances there are for mistakes. Just one wrong number can affect the whole payroll, and these errors often go unnoticed until an employee points them out.
2. Delayed salary payments: Manual payroll depends on getting the right data on time, the right person being available, and approvals coming through before the deadline. When any of those break down, salaries are late. Most employees understand a genuine mistake once. After that, it starts to feel like a pattern. Research on wages and timely payments consistently shows that salary delays are one of the leading causes of employee disengagement and turnover.
3. Incomplete employee records: Payroll accuracy depends on having up-to-date information. If a bank account is outdated, a tax ID is missing, or a salary change isn’t recorded, these small gaps can lead to errors, often at the moment employees expect to be paid.
4. Compliance complications: PAYE, pension, NSITF, NHF, and NHIS all have different rates, deadlines, and remittance steps. The new rules from the Nigeria Tax Act 2025 make it even harder to keep up if you’re doing everything manually.

The bigger your team gets, the more these challenges compound. Which is exactly why how you structure the process matters.

How Businesses Can Improve Their Payroll Workflow

Here’s some good news: most payroll problems are easy to fix. They usually come down to process issues, so you can solve them by improving your processes.

1. Define a payroll calendar: Set fixed dates for collecting data, making calculations, reviewing, approving, and paying. When everyone knows the schedule, you no longer have to rely on someone to remember to start the process.
2. Keep employee records current: Whenever there’s a salary change, a bank update, or a new hire, update your payroll records right away, not at the end of the month.
3. Standardise your approval process: Have one person prepare payroll and another person review and approve it. This simple step helps catch most mistakes before they affect employees.
4. Automate repetitive calculations: PAYE, pension, and statutory deductions are often subject to change. So automating these steps reduces errors and ensures you always use the correct rates. Payroll management tools designed for Nigerian businesses can help with this.

Building a Reliable Payroll Workflow

Getting payroll right once might be luck, but doing it right every month takes a solid process.

1. Assign clear ownership: One person or team should manage payroll end-to-end. When everyone assumes someone else is handling it, important tasks can be missed.
2. Document your process: Write down every step, including who does each task, when it needs to be done, and how. If the usual person is away, this guide will help keep everything on track.
3. Review after every cycle: Spend 15 minutes after each payroll run to spot any issues or slowdowns. Making small improvements each time will help your process run smoothly in the long term.
4. Keep your records properly: Payslips, remittance receipts, and reconciliation reports; organised and accessible for at least six years. Good records make audits straightforward and employee queries easy to resolve.
