Reporting Capital Gain Losses via letter

Hi. In the tax year 2022 - 2023 I transferred certificated shares to an Investment Platform, where they were held in a general account in digital format. I subsequently sold some of these shares and repurchased them in an ISA, via the Bed and ISA process. As the shares in the general account were sold at a price that was lower than the acquired cost, I suffered a loss. Could you please confirm that I can therefor treat this as a capital gain loss, which could be carried forward for future years, Assuming that this loss can and should be reported, I would propose to do so via writing a letter to HMRC, (since I am not required at present to submit an annual self assessment). Could you please advise what information/evidence I should provide in the letter. Awaiting your reply. Kind Regards. Charlie

Hi,

The repurchase of the shares within the ISA would not be affected by the 30 day bed and breakfasting rule. This is because the ISA manager is deemed to have bought the shares, and so the disposal would be calculated in the normal way for capital gains purposes. You can see guidance here:

CG21500 - Individuals: Losses: assessment

Thank you.
