CGT on property abroad

Hi, I have sold a property abroad this September 2024. Firstly, my understanding is that I can report the CGT in my self assessment for 2024/25. Secondly, can I use the same HMRC Euro/GBP exchange rate for the sales and purchase. Please note that the purchase was about twenty years ago. Any help is appreciated.

Hi Reijo Koverskoi,
Yes, you will report this in your tax return.
You need to use the exchange rates for the tax year the house was bought and again then sold. HMRC rates are at:

Thank you. 

Hallo, trank you for the reply. However, HMRC does not have 20 year old exchange rates. So what rate should I use. Thank you in advance.
