What is Withholding Tax (WHT) in Nigeria?

Withholding tax is an advance payment of income tax deducted at source from specific payments such as contracts, rent, dividends, and professional fees. It’s a tax collection mechanism used by both the Federal Inland Revenue Service (FIRS) and State Internal Revenue Services (SIRS).

Common payments subject to WHT include:

Consultancy and professional services
Rent and lease payments
Dividends and interest
Royalties
Contracts and supplies

The deducted tax must then be remitted to the appropriate authority by a specified due date.

FIRS: Through the TaxPro Max portal.
SIRS: Each state has its own online remittance system (e.g., Lagos, Rivers, or Oyo IRS portals).

3. Applicable Rates

WHT rates range from 5% to 10%, depending on the nature of the transaction (services, rent, dividends, etc.).
