In 2026, under the Nigeria Tax Administration Act (NTAA) 2025, you can request an extension for tax filing, but it is not guaranteed. The Nigeria Revenue Service (NRS) has strict guidelines for such requests.
1. How to Apply for an Extension
To get more time to file your Company Income Tax (CIT) or other annual returns, you must follow these steps before the original deadline:
- Written Application: You must apply in writing (or via the TaxPro Max "Support" or "Requests" module) to the Tax Controller of your local NRS office.
- Timing: The application must be submitted before the expiration of the statutory filing date (e.g., if your deadline is June 30th, you should apply by early June).
- Justification: You must provide a "good cause" for the delay (e.g., a catastrophic fire at your office, severe illness of a key officer, or a major system migration).
- Max Extension: The NRS can typically grant an extension of up to 2 months at their discretion.
2. The "Pay First" Requirement
Even if you are granted an extension to file your returns (the paperwork), the NRS usually still requires you to:
- Pay an Estimated Tax: You must pay a portion of the tax you think you owe by the original deadline.
- Apply for Installmental Payment: If the delay is financial, you can apply separately to pay your tax in up to three installments.
3. Penalties for Late Filing in 2026
If you don't get an extension and you miss the deadline, the new 2026 penalties are quite high:
- Flat Fine: ₦100,000 for the first month of default.
- Monthly Accumulation: ₦50,000 for every subsequent month the return remains unfiled.
- Interest: Unpaid tax will accrue interest at the Central Bank of Nigeria (CBN) Monetary Policy Rate (MPR), which is currently very high (ranging from 18% to 27%).
4. Summary Checklist for Extensions

Special Case: LIRS (Lagos State)
If you are an employer in Lagos filing Annual Returns (Form H1), the deadline is January 31st. The LIRS rarely grants extensions for this, as the digital eTax portal is expected to be used year-round to avoid last-minute issues.
