Overview
- HM Treasury is modelling a national property levy paid by sellers on home sales above about £500,000, according to new reports.
- Under the option described, the charge would be due at sale and calibrated to property value, with stamp duty surcharges on second homes reportedly unchanged.
- The Chancellor is also said to be examining whether to apply capital gains tax to very high‑value primary residences.
- Tax advisers and campaign groups warn a CGT change could depress transactions and revenues, proposing alternatives such as land value taxes, proportional annual charges, higher levies on second homes, or comprehensive council tax reform.
- The Treasury says it is prioritising economic growth and keeping income tax, employee national insurance and VAT rates unchanged, and any decisions are likely to come at a Budget with a longer‑term council tax replacement also under review.
