What stamp duty you’ll pay on a house in England or Northern Ireland — including first-time buyer relief and the extra on a second home. Stamp duty is not one number attached to a price. Four things can apply at once: the standard bands, first-time buyer relief that takes you to nothing below £300,000, a 5% surcharge that lands on the whole purchase price rather than just the top slice if this is a second home or a buy-to-let, and another 2% if you are buying from abroad. They stack. Two of those changed recently — the bands went back up on 1 April 2025 and the second-home surcharge rose from 3% to 5% in October 2024 — so a general-purpose AI will often hand you a number that was right eighteen months ago and is now thousands of pounds out. Scotland and Wales charge different taxes altogether, LBTT and LTT, and are not covered here.
