Hi,
Article 11(1) of the double taxation agreement advises the interest arising in the UK and paid to a resident of Hong Kong, may be taxed in Hong Kong. c
Clause 11(2) goes on to state that interest may also be taxable in the UK, unless at least one of the conditions in paragraph 11(3) are met.
Clause 11(3)(ii) relates to an individual. This means that if the beneficial owner of the UK interest is an individual, resident in Hong Kong, then the interest is only taxable in Hong Kong.
Take a look at the guidance in this link:
UK/HONG KONG DOUBLE TAXATION AGREEMENT AND PROTOCOL
Thank you
