How it works
Home movers pay 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 nothing up to £300,000 and 5% from £300,001 to £500,000. If the price is over £500,000, there's no first-time buyer relief and standard rates apply.
Buying an additional property (like a buy-to-let or second home) adds 5% to every band. Buyers who aren't UK resident pay another 2%. Scotland and Wales have their own taxes (LBTT and LTT).
