I have recently sold a UK property - March 2025 - that I lived in for a number of years and then rented out when my partner and I purchased a property together. I appreciate that I have to pay CGT on this sale however just wondering if I have to pay the CGT immediately or if I can add it to my HMRC tax return for 2024-2025 which I will be submitting later this year? I am getting mixed messages on when I should pay the CGT. Many thanks.
