Dear Sir, I purchased Lloyds Bank shares in 2007 and 2008, worth £33k in each deal at the time. In Oct 2021 and Mar 2022, I sold out the shares and incuured a total loss of £30k. Can I use the loss to offset or reduce my year 2023/24 income tax? If I can, how to do it in my self-assessment? I have tried a few times on HMRC self-assessment website, but cannot access either box 41 ('Losses used against income – amount claimed against 2023–24 income') or Box 43 ('Losses used against income – amount claimed against 2022–23 income). Please help. Thank you. Shao
