Capital gains tax take overtakes stamp duty Britons are paying more capital gains tax than stamp duty for the first time in 15 years. Taxpayers last year paid a record £18bn in taxes on investment profits, £3bn more than was paid in stamp duty. HMRC figures show that CGT receipts grew by £3bn year-on-year while stamp duty rose by only £1bn due to a slowdown in the property market. Sean McCann, of advisers NFU Mutual, which carried out the analysis, said buy-to-let landlords offloading property was behind the surge in CGT receipts. He said: “With the value of the average UK property having increased by 70% over the last 10 years, many are facing substantial bills,” adding: “More buy-to-let landlords are offloading property because of increasing mortgage rates and are being hit based on the rise in the value of their property.” The Office for Budget Responsibility has forecast a £4.7bn drop in stamp duty receipts in 2023/24 due to a housing market downturn.
