Worked example

GOV.UK's own example: an additional property bought for £300,000 on or after 1 April 2025 pays 5% on the first £125,000 (£6,250), 7% on the next £125,000 (£8,750) and 10% on the final £50,000 (£5,000). Total: £20,000. Put £300,000 into the calculator above and you get the same.

Things that change the answer

  • Properties under £40,000 do not pay the 5% surcharge.
  • Companies buying residential property usually pay the higher rates from the first property.
  • Replacing your main home can mean the surcharge does not apply, or can be reclaimed if you sell the old one within three years.
  • Scotland and Wales have their own taxes, Land and Buildings Transaction Tax and Land Transaction Tax, with different rates. This calculator does not cover them.
  • Mixed-use and six or more dwellings can be taxed at non-residential rates. Take advice.
This calculator gives an estimate for straightforward purchases. Reliefs and exceptions depend on your circumstances, so confirm the figure with your conveyancer or HMRC's own calculator before you exchange.
