Capital gains tax receipts hit £24.3bn in 2025/26, up 77% year on year, HMRC figures show

New HMRC figures show capital gains tax receipts reached just under £24.3bn in 2025/26, up 77% on the previous year and 244% over the decade. The jump reflects the annual allowance falling to £3,000 and rates rising in October 2024 to 18% and 24%. For sellers of second homes or buy-to-let property, more of any gain is now taxable, sharpening the incentive for landlords to weigh exit timing carefully. Receipts cover all asset disposals, so property sales are only part of the rise.
