Hi.
If you are resident in the UK then by default, you are taxed using the arising basis on your world-wide income regardless of whether your bring it to the UK or not, so you would declare your
HK property income in the foreign section of a tax return and claim a foreign tax credit of up to 100% of the foreign tax paid. You will need to review the tax treaty between Hong Kong and
the UK, to determine if any of your Hong Kong sources of income are only taxable in Hong Kong. Have a look at the article on employment, interest etc to see how you are affected by them:
UK/HONG KONG DOUBLE TAXATION AGREEMENT AND PROTOCOL
Thank you.
