Report on Capital Loss for future use

Dear HMRC, I have a query regarding the reporting of capital losses for self-assessment. Assumptions: (1) Financial year: 23/24 (2) Capital gain allowance: £6,000 (3) Capital gain on Share A: £6,000 (4) Capital loss on Share B: £6,000 (4) Capital loss on Share C: £6,000 I am aware that capital losses can be carried forward indefinitely to offset gains in future years. If I intend to declare the loss, could you please advise if the following procedures are correct: Self-Assessment Form SA108 2023: Page CG2 (1) Box 26 input: £6,000 [capital gain of share A] (2) Box 27 input: £12,000 [capital loss of shares B + C] Kindly correct me if I am mistaken. Thank you for your guidance.

Hi,

Gains and losses should be reported as in year losses will be used first even if it means you lose out on the anual exempt amount. further guidance on completing the page is at
