Work out Stamp Duty in England and Northern Ireland
An educational estimate using GOV.UK rates (checked October 2026). Your solicitor confirms the actual amount. It does not cover Scotland or Wales.
How the calculation works
Stamp Duty is charged in slices: each rate applies only to the part of the price in its band. The calculator uses the GOV.UK residential rates that apply from 1 April 2025: 0% up to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5 million and 12% above.
First-time buyers pay 0% up to £300,000 and 5% from £300,001 to £500,000, with no relief above £500,000. Additional properties of £40,000 or more pay 5% more on each band, and non-UK residents pay 2% more. The total is rounded down to the nearest pound. It does not cover leasehold rent, mixed-use or non-residential property, company purchases or other reliefs.
