How It Works

Stamp Duty Land Tax (SDLT) is payable on property purchases in England and Northern Ireland above certain thresholds. From April 2025, the standard nil-rate band is £125,000. Rates then rise through bands: 2% (£125,001–£250,000), 5% (£250,001–£925,000), 10% (£925,001–£1.5m) and 12% (above £1.5m).

First-time buyers purchasing their first home up to £500,000 pay no SDLT on the first £300,000, then 5% on the portion from £300,001 to £500,000. Properties above £500,000 do not qualify for first-time buyer relief.

If you already own a property and are buying an additional one (second home, buy-to-let), a 5% surcharge applies to the entire purchase price on top of standard rates. This calculator handles all three scenarios — standard, first-time buyer and additional property.

Example: £350,000 property (standard rates)

  1. £0–£125,000 at 0% = £0
  2. £125,001–£250,000 at 2% = £2,500
  3. £250,001–£350,000 at 5% = £5,000
  4. Total SDLT: £7,500 (effective rate: 2.14%)
