About this tool

Stamp Duty Land Tax is charged in bands — each slice of the price is taxed at its band rate (post-2025 standard: 0% to £125k, 2% to £250k, 5% to £925k, 10% to £1.5m, 12% above). Buying a second home or buy-to-let adds +5% on every band. This calculator shows the slice-by-slice breakdown so you can verify any online quote. Scotland (LBTT) and Wales (LTT) have different bands.
