DT18505 | Double Taxation Relief Manual: Taiwan: interest
From HM Revenue & Customs · Double Taxation Relief Manual
The Taiwanese tax deducted from interest at the agreement rate of 10 per cent qualifies for credit as a direct tax.
The reduction to the above rate is not given if the interest is effectively connected (see INTM153110 fifth sub-para.) with a business carried on by the United Kingdom resident recipient through a permanent establishment in Taiwan or with a fixed base in Taiwan from which they perform professional services.
However no tax should be deducted by Taiwan from interest
paid to and beneficially owned by the United Kingdom government or a United Kingdom local authority, or an agency or instrumentality of the United Kingdom government or local authority;
paid in respect of loans made, and loans debt-claims or credit guaranteed or insured by an approved agency or instrumentality of that other territory. The United Kingdom Export Credits Guarantee Department is specified as an approved agency/ instrumentality for this purpose.
