What is stamp duty?

Stamp duty (Stamp Duty Land Tax in the UK) is a tax paid by the buyer on residential property purchases above certain thresholds. It's calculated in tiered bands — you pay a percentage on each slice of the price within each band, not a flat rate on the whole price. First-time buyers, second-home owners, and non-residents face different rates and reliefs.

How to use this stamp duty calculator

Enter the property purchase price and select your buyer status (first-time buyer, mover, or additional property). The calculator returns the stamp duty owed, the breakdown by band, and the effective rate. Always run this number before making an offer — stamp duty can add 3–10%+ to your upfront cost on top of deposit, legal fees, and survey costs.

First-time buyer relief and second-home surcharges

First-time buyers in England and Northern Ireland pay no stamp duty on the first £425,000 (with reduced rates up to £625,000), which can save up to £11,250. On the other side, buying a second home or buy-to-let property adds a 3% surcharge on every band — turning a £20,000 bill into £35,000. Non-resident buyers pay a further 2% on top. Always model your exact circumstances before assuming a headline rate, because reliefs and surcharges can swing the bill by tens of thousands.
