Foreign capital losses carry forward and self assessment form

Dear team, I appreciate your advice. I have foreign capital losses (short term ang ling term losses) for year 2019-20, 20-21 and 21-22. I was not aware if that could be included in UK self assessment in those eespective tax returns. These losses are clearly recorded in overseas country tax returns. 1) I wonder if there is an option for me to amend or claim against those losses here? 2) If yes, do they need to be claimed only against overseas income or can it be substracted from gross UK income? 3) Is there a time-limit to carry forward such a loss? Thank you.

Dear HMRC team, May I have response to above query please. Thanks.

Hi,

Yes, Foreign Capital Losses can be set against UK Capital Gains. Detailed guidance on quantifying, calculating and claiming Capital Losses is provided at CGT15800.

Thank you.
