How SDLT works in 2026/27
SDLT is a "slice" tax: each portion of the price is taxed at its own rate. From 1 April 2025 the standard residential bands are 0% to £125,000, 2% to £250,000, 5% to £925,000, 10% to £1.5m, and 12% above.
First-time buyers pay nothing up to £300,000 and 5% on the slice to £500,000, but the relief is lost entirely above £500,000. Buying an additional dwelling adds a 5% surcharge to every band, and non-UK residents add a further 2% on top.
Scotland (LBTT) and Wales (LTT) have their own separate systems.
