Missed Your Tax Deadline in Nigeria? Here Are the Penalties You Could Face

Nigeria’s tax laws set deadlines for filing returns and paying taxes, and failing to meet these obligations can attract administrative penalties, interest and further enforcement action. Understanding which deadlines apply to you and what happens when you miss them can help you avoid unnecessary costs and keep your tax affairs in order.

When Are Tax Returns Due in Nigeria?

For individuals, the annual income tax return is generally due by 31 March each year. This applies to employees, self employed professionals, traders and other individuals required to file returns. Under the Nigeria Tax Administration Act 2025, individuals must report their income in accordance with the applicable filing requirements, even where tax has already been deducted from their earnings.

For example, an employee whose income tax is deducted through Pay As You Earn (PAYE) should not automatically assume that their employer’s monthly deductions remove the need to file an annual return.

Companies have a different filing timetable. A company’s income tax return is generally due within six months after the end of its accounting year. This is separate from the annual personal income tax return required of individuals who operate businesses in their own names.

Other obligations, including monthly tax remittances and employer returns, have their own deadlines. The date that applies to you therefore depends on the type of tax and your status as a taxpayer.

What Happens If You Fail to File?

Under section 101 of the Nigeria Tax Administration Act 2025, a taxable person who fails or refuses to file a required return, or knowingly submits an incomplete or inaccurate return, is liable to an administrative penalty of ₦100,000 in the first month of default and ₦50,000 for each subsequent month the failure continues.

This makes late filing more than an administrative inconvenience. Leaving a return outstanding can allow the penalty to accumulate, while incomplete or inaccurate information can create additional compliance problems.

Failure to file may also make it harder to demonstrate your actual income and tax position. Where a taxpayer does not provide the required information, the relevant tax authority may take further steps permitted by law to assess or recover tax.

Filing accurately and on time helps establish a clear record of your income, eligible deductions and tax obligations. If you discover an error in a return already submitted, seek guidance on the appropriate process for correcting it rather than ignoring the discrepancy.

What If You File but Do Not Pay Your Tax?

Filing a return and paying the tax due are separate obligations. You may submit your return within the required period but still face consequences if you fail to pay an assessed tax liability by its due date.

Section 65 of the Nigeria Tax Administration Act 2025 provides for a penalty of 10% of the unpaid tax, together with applicable interest. For naira payments, the Act provides for interest based on the Central Bank of Nigeria’s prevailing Monetary Policy Rate plus a spread determined by the Minister. The applicable interest rate must be checked against the relevant rules and orders in force for the period concerned.

The tax authority may also issue a demand notice. If the tax remains unpaid 30 days after service of that notice, the law permits further recovery action.

If you cannot pay the full amount when it falls due, do not assume that leaving the liability outstanding will resolve the problem. Contact the relevant tax authority to understand the options available in your circumstances. Section 66 also allows the authority to remit all or part of a penalty or interest where good cause is shown, although relief is not automatic.

How Can You Avoid These Penalties?

Start by identifying the filing deadlines that apply to your income and business activities. Keep a calendar for annual returns, tax payments and any recurring obligations, and give yourself enough time to prepare before each due date.

Maintain accurate records throughout the year rather than waiting until a return is due. Income statements, invoices, bank records, receipts, evidence of tax already deducted and supporting documents for eligible deductions can help you prepare a complete return and explain your calculations if requested.

If you have already missed a deadline, establish which return or payment remains outstanding and take steps to address it promptly. Ignoring the obligation may allow penalties to increase or lead to further action by the relevant authority.
