I made some trading losses of around £20,000 in March 2021. I am seeing some conflicted information online about the rules with regards to carrying forward losses. Am I correct to assume that if I declare this loss before March 2025, I can carry these losses forward indefinitely to offset against future capital gains or has my opportunity to declare these losses expire following the 3rd preceding tax year end which I understand would be 4th April 2024 (end of 23/24) Also, if they can still be declared, can this be done at any point during the year as an individual submission?
