Filing Withholding Tax (WHT) returns is a monthly obligation for Nigerian businesses. It is the process of declaring the taxes you deducted from your vendors and paying that money to the government. In 2026, this process is strictly digital, and the deadlines are non-negotiable.
The Deadline: The 21st Day
Much like VAT, WHT returns must be filed and paid by the 21st day of the following month. For example, any tax deducted in March 2026 must be remitted by April 21, 2026. Failure to meet this deadline results in an automatic 10% penalty plus interest at the CBN prevailing rate. For more on timelines, see our Nigerian Tax Compliance Checklist.
How to File WHT Online: Step-by-Step
- Log in to TaxPro Max: Access your dashboard using your corporate TIN.
- Upload WHT Schedule: You must upload an Excel file containing the vendor’s name, TIN, address, nature of the transaction, and the amount deducted.
- Generate Payment Reference: Once the schedule is validated, the system generates a Remita Retrieval Reference (RRR).
- Make Payment: Pay via online banking or at any commercial bank branch.
- Download Credit Notes: After payment, the system generates digital credit notes for your vendors. Learn more about this in Withholding Tax Credit Notes Explained.
Avoiding Common Errors
- Authority Mismatch: Ensure you pay the NRS for companies and the State IRS for individuals.
- Wrong Rates: Double-check your WHT calculations before uploading.
Practical example: A company that fails to file its WHT returns for six months could face thousands of naira in accumulated interest. For official templates and portal support, visit the Remita or NRS websites. To see the impact on your cash flow, read about tax penalties in Nigeria.”
