March 31 Tax Deadline in Nigeria (2026): Is It PAYE or Annual Tax Return?

Last updated: March 27, 2026

If you have been hearing about the March 31 tax deadline in Nigeria and wondering whether it means PAYE or something else, you are not alone. Many taxpayers mix these deadlines up, and getting it wrong can lead to missed filings, avoidable penalties, or unnecessary panic.

The short version is this: the March 31 tax deadline in Nigeria usually refers to the annual tax return for individuals, not the routine monthly PAYE remittance deadline employers deal with after deducting tax from salaries.

As of March 27, 2026, that matters because the deadline is only a few days away.

Quick answer (in 10 seconds)

March 31 -> Individual annual tax return
January 31 -> Employer annual PAYE return for the previous year
Monthly PAYE remittance -> A separate deadline, commonly presented by tax authorities as the 10th of the following month

What the March 31 Tax Deadline in Nigeria Actually Means

March 31 is generally the annual return deadline tax authorities use for individuals.

FCT-IRS says individual taxpayers are required to file returns on or before March 31 every year. Edo State IRS also issued a March 19, 2026 reminder urging individuals, professionals, and business owners to file annual tax returns by March 31, 2026.

The legal basis matters too. Section 13 of the Nigeria Tax Administration Act, 2025 requires every taxable person to file an annual return of income, while section 14(3) makes clear that an employee still files an annual return of income from all sources.

In plain English, March 31 is usually about your yearly tax return as an individual. It is not the same as the usual monthly PAYE remittance deadline.

Who Needs to Pay Attention to March 31?

If you fall into any of these groups, the March 31 deadline may matter to you:

Salary earners
Freelancers and consultants
Business owners and sole proprietors
Professionals
Employees with income from more than one source

Is March 31 the PAYE Deadline?

Usually, no.

This is where the confusion starts:

The employer's annual PAYE return is due by January 31 each year for the preceding year
The individual's annual return is the one generally associated with March 31
Monthly PAYE remittance follows its own separate timeline after salary deductions

FCT-IRS and LIRS publicly present monthly PAYE remittance as due by the 10th of the following month. That is why saying "March 31 is the PAYE deadline" is usually too broad and, in most cases, wrong in practice.

The safest way to explain it is this: March 31 is generally not the routine monthly PAYE remittance deadline, and it is also not the main annual employer PAYE return deadline.

The 3 Tax Dates to Remember

The easiest way to keep it straight is to remember these three dates:

March 31 -> individual annual tax return
January 31 -> employer annual PAYE return for the previous year
Monthly PAYE remittance deadline -> usually presented by tax authorities as the 10th of the following month

Once you separate those three dates, the March 31 confusion becomes much easier to understand.

What Employers Should Know Right Now

As of March 27, 2026, the key employer annual PAYE deadline for this cycle has already passed.

Section 14(1) of the Nigeria Tax Administration Act, 2025 says an employer must file its annual PAYE return by January 31 each year for employees in the preceding year. Edo State IRS even announced an extension of the employer annual PAYE filing deadline to February 14, 2026, which reinforces the point: employer annual PAYE filing was treated as a January-to-February issue, not a March 31 issue.

So if you are an employer reading this now, the real question is usually not, "Is March 31 my employer annual PAYE deadline?" The more useful question is whether you still have a monthly remittance obligation, an employee-related filing issue, or a payroll documentation problem to sort out.

What Employees and Individuals Should Know Right Now

If you are a salary earner, entrepreneur, freelancer, or professional, March 31 matters because tax authorities are currently highlighting it as the annual filing deadline for individuals.

That matters even if PAYE has already been deducted from your salary. Under section 14(3) of the Nigeria Tax Administration Act, 2025, an employee still files an annual return of income from all sources in line with section 13.

That is why many people get caught off guard. They assume that once PAYE has been deducted, there is nothing else to do. In reality, PAYE deduction and annual return filing are related, but they are not the same compliance step.

If you want a simple place to estimate your numbers before filing, start with the Personal Tax Calculator (PAYE). If you want broader product questions answered first, see the FAQ.

Why States Can Mention March 31 Slightly Differently

The overall pattern stays the same:

March 31 is the individual annual return deadline in current tax authority guidance
January 31 is the employer annual PAYE return deadline under section 14(1)
Monthly PAYE remittance is a separate deadline

But state tax authorities may still issue notices around March 31 that mention different forms, filing channels, or local compliance steps.

Edo is a good example. In early 2026, it issued notices covering both employer filings and individual returns, but they were not the same obligation. They had different deadlines and different forms. The safest approach is to start with the general rule above, then confirm your state's exact filing instructions before you submit anything.

What Happens If You Miss It?

Missing the deadline is not just a formality.

Under the current 2026 framework, failure or refusal to file returns can trigger administrative penalties, and those penalties can continue to build if the default continues. That is why it is worth confirming whether you are dealing with an individual annual return, an employer annual PAYE return, or a monthly remittance obligation before the deadline passes.

This is also why deadline confusion is expensive. The wrong assumption can turn a simple compliance task into an avoidable tax problem.

Final Word

So, is March 31 the PAYE deadline in Nigeria?

Usually, no.

March 31 is generally the deadline tax authorities are currently using for individual annual tax returns. The employer's annual PAYE return is generally due by January 31, while monthly PAYE remittance follows a separate post-deduction timeline that tax authorities commonly show as the 10th of the following month.

That is the distinction that matters this week: March 31 is real, important, and urgent, but it should not be confused with the normal monthly PAYE remittance deadline or the employer's annual PAYE return deadline.
