Reporting To HMRC On A Split Estate

I am the Executor to my late Father’s estate. The estate comprises a bungalow, gardens and a piece of land to the rear. Before the estate went on the open market for sale, a price was agreed for a section of the land (STC) to an adjacent neighbour. A price has also now been agreed for the bungalow and remaining land and is awaiting exchange of contracts and completion. Completion of the sale of the separate section of land to the neighbour took place on 21st December 2023. My Accountant has calculated for me what the Capital Gains Tax liability will be on the whole estate. Inheritance Tax is not applicable. The sale of the separate section of land to the neighbour is,in itself, not subject to CGT- the gain between the estimated value of that section of land at the time of my Father’s passing and the subsequent agreed price, being £3,000. However, this land does form part of the overall estate, which is subject to Capital Gains Tax- effectively there are two separate transactions. My question is: Do I need to report anything to HMRC, at this juncture, in respect of the sale of the separate section of land to the neighbour? Or is it swept up with the Capital Gains Tax return when the remaining sale is completed- expected to be in a couple of months time. Thank you.

Hi Mark Taylor,
It is 2 separate transactions and the sale of the property needs to be declared under the 60 day residential property rule.
The land is different and would be included in the return. 
If you have used any of the annual exempt amount when working out any gain for the land, it  should be taken into account when filing the property disposal return.
When it comes to filing the end of year tax return, both disposals should be declared on the return with only one annual allowance being given, further guidance is at:-

Thank you.

Thank you for clarifying that for me. Regards.
