How we calculated your result

Gain = sale price − purchase price − allowable costs. Subtract the £3,000 Annual Exempt Amount. The remainder is taxed at 18% to the extent it fits in your basic-rate band, and 24% above. Your other taxable income fills the basic-rate band first.

Official UK rules in simple English

  • Annual Exempt Amount: £3,000 (down from £12,300 in 2022/23).
  • Rates: 18% basic / 24% higher (residential and other unified Oct 2024).
  • Allowable costs: stamp duty paid, legal fees, agent fees, capital improvements (not maintenance).
  • Pay within 60 days of completion via HMRC’s online service.

Common pitfalls to watch out for

  • 60-day reporting trap

    Late returns trigger penalties even if no tax is due.
  • Improvements vs maintenance

    A new extension counts. Replacing the boiler doesn’t.
  • PPR relief only on main home

    If you ever lived in the property, Private Residence Relief reduces the gain pro-rata.

Frequently asked questions

Can I offset previous losses?
Yes — capital losses from prior years can reduce taxable gains. Must have been reported within 4 years.
