Report capital losses for previous years

If any capital loss of disposal of shares for previous years were not reported in the corresponding tax turns for those years, can I amend the tax return for the year 2022-2023 (which is currently available to amend) and report those losses there as the capital losses taken forward for future uses? Thanks a lot.

Hi,

The 4 years only refers to HMRC being notified that they exist. the loss itself can be carried forward indefinately.

You are now to late to make a claim for these from 2019 to 2020.

Thank you.
