Hi,
You will need to review the tax treaty between the UK and Hong Kong at:
Hong Kong: tax treaties, to determine whether your sources of income are taxable in Hong Kong or UK or both countries.  
Where your overseas income is taxable in the UK,  you will need to submit a self assessment tax return and where tax is payable overseas on that income, you can claim a foreign tax credit.
Thank you.

Hi,
As you have moved abroad, you can no longer contribute to the ISA after the end of the tax year that you moved.  
No-one else will be able to contribute to it either.  
You can still keep your savings in the ISA and get tax relief on money and investment held in it.
Thank you.

Hi,
It would depend on the type of pensions as in net and not net pension.
Please contact personal tax on 0300 200 3300 if the question is in relation to the tax for further advice.
Thank you.

Unfotunately these costs are not allowable.  You can only claim expenses that are incurred in the actual letting of the property.

Hi,
On the basis of the informastion provided, split year treatment would apply for the 2021/22 tax year, and the UK part of the year would commence on the date you rented your apartment (ie the date from which you had your only home in the UK).
If your only income from the date you arrived in the UK was the bank interest figure quoted, you would not have to complete a 2021/22  tax return. However if you are in receipt of a foreign pension, you would have to register for Self Assessment:                                                             
Check if you need to send a Self Assessment tax return
Thank you.
