I'm stuck on the CGT pages of self assessment. I have (I think) a simple case. I sold some shares (1 transaction) and the proceeds exceeded £50k, but the gain was less than the 2023/24 allowance of £6k, so I don't believe there is any CGT to pay. Do I report this on the form as a loss? It's not clear whether I should subtract the allowance as well as the fees/sale costs, and report balance as a loss (there is no reference to the allowance on the online form, it only refers to reliefs and exemptions which don't apply to me) ? I will attach a copy of the confirmation of sale (which only shows the sale proceeds and costs) and a separate document showing how I've worked out the gain based on the original share price paid and the sale price.
