Withholding tax
From ACT Wiki
(WHT).
Withholding tax is a tax deducted at source on earnings, including employment income, dividends and interest payments, and can also include intangible services.
WHT is subject to some exemptions.
For example in the UK there is an exemption for any payments of interest on a quoted Eurobond, being any security issued by a company and the security is listed on a recognised stock exchange and carrying a right to interest.
There is also an exemption for interest paid by banks in the ordinary course of their business.
