CGT and completing SA100 after SA108 has been submitted and the tax due paid

Hi, I sold my part share in a residential property last November. SA108 was completed and the tax that was due was paid. I am now completing SA100 for 2023/24 and finding it very difficult to navigate the section on Capital Gains. This property sale was my only gain for the tax year. I am assuming that having submitted SA108 that I do not need to use the worksheets. To date every effort I have made has produced a RED response. Can you offer guidance? All other tax forms have by comparison been easy for me to use. Please can you provide me with guidance on which sections need to be completed and if any will be pre-filled from my SA108 submission.

Hi,
For residential property you should have reported using the property disposal return -  Tax when you sell property.
If this has been submitted then when it comes to completing the actual tax return you need to report the same info again under the residential property section.
You then show the details for disposals already reported so that you are not charged twice.
Further guidance on how to complete the page is at Capital Gains Tax summary notes
Thank you.
