Reporting CGT on Overseas Property sale

I have Lasting Power of Attorney for my aunt. Together with her husband she bought a French property in 1987, then the adjoining plot in 1988. When the husband died she inherited (in 2024) his 50% share of the combined property. It has now been sold, as one property. On the self assessment capital gains page (and computation sheet) how do I present these 3 acquisition dates (1987, 1988, 2024) and 3 acquisition values, given that it has been sold as a single asset?

Hi Frenchenglish Taylor,
There is no capial gains tax liability on the transfer of assets between spouses or civil partners, so your aunt would acquire each 50% share of a property at the
value it was acquired for in 1988 and 2024.  
This would mean that the acquistion cost of 100% of each property is the value it was acquired for.  
Add the three together and you have the acquisition cost, which can be deducted from the single disposal value.
Thank you.

Hi, Thank you for HMRC Admin support. 1. After studying the capital gain summary note and the eligibility of PRR. My parents and I know that they are eligible to claim the PRR on their old residential flat in Hong Kong. I have calculated the value for relief. However, I could not find a box to fill in this figure. It seems from the SA108 that: box 6 = box 4 minus box 5. Should box 5 (allowable cost) also include this figure of PRR relief as part of the cost? Or any other place I can reflect this figure? 2. I do not perform any "real time transaction returns", therefore I just need to leave the box 11 blank. Am I right? Thank you. 

Hi, I currently own 50% of an apartment, with the remaining 50% owned by my mum. This property has been the main and only residence for my parents and me since 2008 in Hong Kong. I moved to the UK in 2022. In 2025, I plan to transfer (as a gift) my 50% ownership to my mum (a non-UK resident) and then purchase my first home in the UK. Under these circumstances, will I be liable to pay Capital Gains Tax in the UK, or would I be eligible for full Private Residence Relief? Thank you.

Hi Skinny,
You do not include it, but it should be reflected in the figure declared at box 6 on the SA108. You will include a calculation to show how you have worked out the relief.
Yes, as you are not using real time, you will leave box 11 blank.
Thank you.

Hi Cac,
As it has not been your main and only residence for the whole period of ownership, capital gains is likely to be due. You can see guidance here:
HS283 Private Residence Relief (2025)
Thank you.

Hi, Thanks for the the admin clear explanation. Further questions: 1. Where should I put my calculation? Could I put that in box 54? 2. I noticed that there is a computation work sheet in the SA108 summary notes. Could I also show the computation in this worksheet? 3. Do I need to inform the HMRC the detail address of my sold flat in Hong Kong as information in the SA108? Thank you.

Hi ,
 

You would declare the disposal of a foreign property on SA106 boxes 33 to 40 (:   Self Assessment: Foreign (SA106) ) or teh equivalent boxes in the foreign section of the online tax return .

Hi, Thanks for your reply. There is no need to claim foreign tax relief on the selling of Hong Kong property. 1. Besides the capital gain in the SA108, do I still need to fill in SA106 on the selling of Hong Kong residential property? 2. Since I need to claim the PRR in SA108, I need to do show my calculations of the figure of the PRR. Should I put these calculations in box 54, Can I add additional paper to show the calculations? 3. Do I need to tell HMRC about the details address of the Hong Kong residential property? Thanks for your attention.

Hi Skinny,
1. no  
2 no - please refer to SA108 notes on how to report and yes you can add additional calculations  
3. yes
Thank you.
 

Dear Admin team， Thank you for previous replies. My Hong Kong flat is sold at GBP 179000, and the allowable costs is GBP 36140. and the value of PRR relief is GBP 138524 after calculation. Then, box 4 = 179000 box 5 = 36140 box 6 = 179000 - 36140 - 138524 = 4336. and box 8 PRR Am I right? Thanks.

Hi Skinny,
