Bank Interest

I received foreign bank interests in period of monthly, quarterly and bi-annully, all in foreign currencies. In completing the 2023 tax return, what exchange rate(s) should I apply to each of these interests? Should I just use the monthly exchange rate of April 2023 for all these received interests or monthly exchange rate in the month I received the relevant interest? Please advise.

Hi,

Under the terms of Self Assessment, HMRC does not provide an official exchange rate that you must use. The onus is on the individual to use a just and reasonable exchange rate for each acquisition and disposal. HMRC does list average monthly rates, average annual rates and two spot rates, which can be found here:

Thank you.
