About SDLT
Stamp Duty Land Tax (SDLT) is a tax you pay when buying property or land in England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT).
SDLT is calculated on a tiered basis — you only pay each rate on the portion of the purchase price that falls within each band.
Additional properties (buy-to-let, second homes) attract a 5% surcharge on every band from April 2025.
