I know I shouldn't have left it until today and am now lost - does anyone have a clue about the capital gains bit of tax returns

[MrsFogi]

I need to fill in the bit about selling my flat that I had when I got married and have the calculations but don't know what to put where and the guidance pages haven't really helped me! Any mners willing to hold my had for 5 mins to tell me what to put where?

if it was your main residence you don't have to pay CG tax
