🏠 UK Stamp Duty Land Tax Calculator

Estimate SDLT on residential purchases in England & Northern Ireland using HMRC bands. Covers standard, first-time buyer relief and additional-property surcharge. Estimates only — not tax advice; confirm with your conveyancer and the official rates.

How SDLT works (England & NI, residential)
SDLT is charged in slices — each portion of the price is taxed at its band rate, not the whole price at the top rate.

Standard residential (from 31 Oct 2024):
£0–£125k 0% · £125,001–£250k 2% · £250,001–£925k 5% · £925,001–£1.5m 10% · over £1.5m 12%.

First-time buyer relief: 0% to £300k, then 5% on £300,001–£500k (relief only if price ≤ £500k; above that, standard rates apply). You must never have owned residential property anywhere in the world.

Additional property: +5 percentage points on each band (so the bottom slice is 5%, not 0%). Applies when you will own 2+ residential properties at completion.

Scotland (LBTT) and Wales (LTT) have different bands — this tool covers England & NI only. Always confirm with the official SDLT guidance.

Estimates only — not tax or conveyancing advice. Rates shown are residential England & NI as set in the Autumn Budget 2024 (additional-property surcharge 5%). Rates can change; verify before exchange.
