There is a particular kind of panic that hits a Nigerian small business owner the first time the Lagos State Internal Revenue Service or any state revenue authority shows up at their office asking questions about employee taxes.
Not because they are dishonest. Not because they set out to evade anything. But because nobody properly explained to them that the moment they hired staff and started paying salaries, they became a tax collection agent for the government. Automatically. Without being asked. Without signing up for anything.
That responsibility is called PAYE. And not understanding it is costing Nigerian small business owners money, penalties, and in some cases, serious legal trouble.
This article is going to explain it plainly, from the beginning, so you know exactly where you stand and what you need to do.
What PAYE Actually Means
PAYE stands for Pay As You Earn. It is a system through which personal income tax is deducted from an employee’s salary at source, meaning before the employee ever receives the money, and remitted to the relevant tax authority by the employer.
The logic behind the system is straightforward. Rather than expecting every working Nigerian to calculate their own income tax and pay it to the government at the end of the year, the government requires employers to do that work. You calculate how much tax each employee owes based on their salary, deduct it from their pay, and send it to the appropriate authority on their behalf every single month.
You are not paying extra money out of your own pocket. The tax comes from the employee’s gross salary. But you are responsible for making sure it is calculated correctly, deducted, and remitted on time. That responsibility sits with you as the employer and it does not disappear because your business is small or because you have only two staff members.
Which Tax Authority Do You Pay?
This is one of the first things that confuses Nigerian small business employers and the confusion is understandable because the answer is not always the same.
In Nigeria, personal income tax is administered at the state level, not the federal level. This is different from companies income tax which goes to FIRS. PAYE goes to the State Internal Revenue Service of whichever state your employee is resident in.
So if your business is in Lagos and all your employees live in Lagos, you remit to the Lagos Internal Revenue Service, known as LIRS. If you have employees living in Abuja, their PAYE goes to the FCT Internal Revenue Service. If you have staff spread across multiple states, you technically have PAYE obligations in each of those states.
For most small businesses with a single location and local staff, this is straightforward. You deal with one state revenue authority. But if your business grows and your team becomes geographically distributed, this becomes more complex and you need to plan for it.
The one exception worth noting is for staff in certain categories under federal or unified public service, whose taxes go to FIRS. For a typical private sector small business, however, the state revenue authority is who you are dealing with.
How the Tax Is Calculated
This is where many small business owners either give up or get it wrong. It does not have to be complicated but it does require understanding a few key concepts.
The starting point is an employee’s gross income. This includes their basic salary plus any regular benefits, allowances, and bonuses they receive. Housing allowance, transport allowance, meal allowance, leave allowance — these all typically form part of the income that needs to be assessed.
From that gross income, certain deductions and reliefs are applied before the taxable income is determined. The most important of these is the Consolidated Relief Allowance, which under the Personal Income Tax Act gives every employee a relief of two hundred thousand naira or one percent of gross income, whichever is higher, plus twenty percent of gross income. This relief exists to reduce the amount of income that is actually subject to tax.
Pension contributions also reduce taxable income. Under the Pension Reform Act, employees contribute eight percent of their monthly emoluments to their Retirement Savings Account. This contribution comes off the gross before tax is calculated.
Once you have the taxable income after applying these reliefs and deductions, you apply the graduated tax rates set out in the Personal Income Tax Act. The rates currently work in bands. The first three hundred thousand naira of taxable income is taxed at seven percent. The next three hundred thousand at eleven percent. The next five hundred thousand at fifteen percent. The next five hundred thousand at nineteen percent. The next one million six hundred thousand at twenty one percent. And anything above that at twenty four percent.
What this means practically is that a lower earning employee pays a much smaller effective tax rate than a higher earning one, because the bands protect the lower portions of income with lower rates.
For most small business owners with staff earning modest salaries, the actual PAYE deduction per employee per month is not enormous. The bigger issue is usually not the amount. It is the failure to deduct and remit at all, which is where the problems begin.
When You Must Remit and What Happens If You Do Not
The law is clear on timing. PAYE deducted from employees in any given month must be remitted to the relevant state tax authority by the tenth day of the following month. So tax deducted from January salaries must be with the revenue authority by the tenth of February. February’s deductions by the tenth of March. And so on throughout the year.
This is not a guideline. It is a legal obligation. And missing it triggers penalties.
The penalties for late remittance vary slightly across state revenue authorities but they are real and they accumulate. Beyond penalties, employers who consistently fail to remit PAYE expose themselves to assessment by the revenue authority, which means the authority estimates what should have been paid and bills you for it, often with interest. In more serious cases, revenue authorities can obtain a court order to recover unpaid PAYE and the consequences can include seizure of business assets.
What makes this worse for small business owners is that the employee has already had the tax deducted from their salary. The money was never theirs to keep. When an employer fails to remit it, they have effectively taken their employees’ tax money and used it for something else. Revenue authorities treat this very seriously and rightly so.
The Annual Returns Requirement
Beyond monthly remittance, every employer operating a PAYE scheme is required to file an annual return at the end of the year. This is a schedule that shows each employee’s name, their income for the year, the total tax deducted, and the total remitted. It is a reconciliation document that allows the revenue authority to verify that what was deducted matches what was paid.
In Lagos for example, LIRS requires employers to file their annual PAYE returns by the thirty first of January of the following year. Other states have similar deadlines. Missing this filing also attracts penalties.
This is something many small businesses either do not know about or forget entirely. They remit monthly but never file the annual return and then get a knock on the door from the revenue authority asking for documentation they have not prepared.
Registering as an Employer
Before you can operate a PAYE scheme properly you need to register with the relevant state revenue authority as an employer. This registration gives you an employer tax identification number and brings you into the system officially.
The registration process varies by state but generally involves completing an employer registration form, providing your business registration documents, and supplying details of your employees. In Lagos, this is done through LIRS. In other states, through the respective State Board of Internal Revenue.
If you have been operating with staff and paying salaries without being registered, the most sensible thing to do is to regularise your position voluntarily rather than wait to be discovered. Revenue authorities generally take a less aggressive stance with businesses that come forward proactively than with those who are caught.
What About Casual Workers and Part Time Staff
This is a question that comes up constantly among Nigerian small business owners who use casual labour, contract staff, or part time workers. Do PAYE obligations apply to them?
The honest answer is that it depends on the nature of the relationship. Where someone is genuinely an employee, meaning they work under your control, at your direction, using your tools and resources, and they receive regular remuneration from you, PAYE applies regardless of whether you call them casual or full time.
Where someone is genuinely an independent contractor running their own business, providing services to multiple clients, and bearing their own business risks, the relationship is different and PAYE may not apply in the same way. But that contractor may have their own direct tax obligations.
The danger is that many Nigerian small businesses classify people as contractors to avoid PAYE when the reality of the working relationship is that of employer and employee. Revenue authorities are increasingly looking at the substance of working arrangements, not just the labels. If your “contractor” works only for you, follows your instructions daily, works your hours, and has no independent business of their own, a revenue authority may determine that PAYE should have been applied all along.
Practical Steps for a Small Business Owner Starting Out
If you have staff and you are not currently running a proper PAYE scheme, here is where to begin.
Register with your state revenue authority as an employer if you have not already done so. Get this formalised before anything else.
Set up a simple payroll system. This does not need to be expensive software at the start. A properly structured spreadsheet that captures each employee’s gross income, their reliefs and deductions, their taxable income, and the monthly tax due is enough to get you started. There are also affordable Nigerian payroll platforms that handle the calculations automatically.
Open a separate account or set aside the PAYE amount each month as you process salaries. Do not let it sit in your general business account where it can accidentally get spent. That money is not yours. Treat it that way from day one.
Remit by the tenth of each month without fail. Set a reminder. Make it a non-negotiable part of your monthly financial calendar.
File your annual returns by the deadline. Keep records of everything — payroll schedules, remittance receipts, employee details. If a revenue authority ever questions your compliance, documentation is your only protection.
And if any of this feels overwhelming, engage a small accounting firm or a payroll service provider to handle it for you. The cost is modest compared to the risk of getting it wrong.
The Mindset Shift That Changes Everything
The business owners who handle PAYE without stress are the ones who accepted early that it is simply a cost of having employees. Not a punishment. Not an optional extra. Just part of what it means to be a legitimate employer in Nigeria.
The ones who struggle are usually the ones who kept delaying, kept telling themselves they would sort it out later, kept treating the deducted funds as a float they could dip into. Later eventually becomes a revenue authority assessment with penalties, or an employee complaint, or a due diligence process for a loan or investment that uncovers years of non-compliance at the worst possible moment.
You built your business to be real. Treat the obligations that come with it the same way.
PAYE is not the enemy. Ignorance of it is.
