Brought Forward Losses, self assessment

I have brought forward capital losses from a prior year to offset against this years capital gains. I have added these to box 58 in the online self assessment form which seems to be the correct box but the loss is not reducing the capital gains due. I presume I need to complete another box as well - which one and what else do I need to do?

Hi,

You need to show them as losses brought forward and used in year. This then reduces the capital gain when you get to look at the calculation.

Thank you.

Thanks very much. The calculation is working. I subsequently realised it is a separate offset that isn't for which I created a different post.
