How to report CGT paid on a buy to let property in my SA?

Hi - Where do I include the CGT I've already paid in my Self Assessment? I dont want to pay CGT twice

Hi,
Please have a look at the paper SA108.
Capital Gains summary (2024)
Choose the relevant section for your type of gain, such as residential property.
For residential property you will see box 9 and 10, other property assets and gains are boxes 21 & 22.  
Listed shares use boxes 29 & 30 and unlisted shares use boxes 37 & 38.  
The online tax return does not use the same numbering, so when in the relevant section, look for the boxes with the same wording.
Thank you.
