Hi Lilian Tong
As you are in receipt of overseas income (of any kind) you must declare your share of the income and expenses, in a self assessment tax return (SA100) on supplementary page SA105 (Property) and SA106 (foreign).
On page F4 of SA106, you would complete the boxes 14 to 32 as appropriate. You do not need to work out the foreign tax credit yourself, we will do this for you, provide you submit your tax return by the filing date.
Only fill in box 2 if you want to calculate the FTCR yourself. You can work out the foreign tax credit relief available for the Hong Kong tax paid, using
Relief for foreign tax paid (Self Assessment helpsheet HS263)
or if you submit your tax return.
Foreign notes
Foreign.
For submitting your tax return online, you would tick yes to foreign income and no to claim Foreign Tax Credit Relief on Capital Gains
Thank you
