forign part time job income

I landed UK in June 2022 via BNO visa. I have returned to Hong Kong for a part time job in July and August 2023. The salary is around £22000 and it is reported to the Hong Kong government for taxation. There is no other income otherwise. Do I need to do the self assessment?

Hi ygsam,
Yes,  the tax treaty between the UK and Hong Kong, article 14(2) advises that employment carried out in Hong Kong is taxable in Hong Kong, but  article 14(2)(a) goes on to advise that if you spend less than 183 days in Hong Kong, then it is only taxable in the UK.
 For this reason, you will need to claim a tax refund in Hong Kong and declare the income in a Self Assessment tax return.

Thank you.
