Withholding tax is a tax that the payer of income deducts from income payments such as employment income, interest, dividends, and other types of income. The payer pays the withheld tax directly to the tax authorities on behalf of the recipient. Withholding tax aims to combat tax evasion. It is typically treated as a prepayment of the recipient's final tax liability but may be refunded or result in additional taxes owed depending on the recipient's actual tax situation.
