Remittance basis, UK fund earn Overseas interest

I select the remittance basis this year. This year, I transfer funds (eg. GBP 20000) originally in the UK to an overseas bank and earn interest (eg 1000) overseas, do I need to pay UK tax on this interest earned overseas even if I do not transfer the interest into the UK? Does it matter that the original capital was within the UK? I planned to select the arising basis next year... Do I need to pay tax on this fund (GBP 20000) if I transfer it back to the UK?

Hi,

Please refer to guidance at:

Remittance basis 2023 (HS264)
