Stamp Duty Calculator UK 2025

Our stamp duty calculator uses the official HMRC rates to calculate your Stamp Duty Land Tax (SDLT). Simply enter your property price, select your buyer type, and the stamp duty calculator instantly shows you the tax due. This online stamp duty calculator works as a stamp duty checker and stamp duty estimator to give you accurate results.

To calculate stamp duty, enter your property price into our calculator above. Stamp duty is calculated in bands - you pay 0% on the first £125,000, then 2% on £125,001-£250,000, 5% on £250,001-£925,000, 10% on £925,001-£1.5m, and 12% above £1.5m. Our property stamp duty calculator does this calculation for you instantly.

How much stamp duty you pay depends on the property price and your buyer type. For example, on a £350,000 property, a standard buyer pays £7,500, while a first-time buyer pays just £2,500. Use our stamp duty calculator above to see exactly how much stamp duty you'll pay on your specific property.

To work out stamp duty costs, you need to apply the SDLT rates to each band of your property price. Our stamp duty cost calculator does this automatically. For a quick stamp duty calculation, enter your house price above and select whether you're a first-time buyer, standard buyer, or buying an additional property.

Estimated stamp duty is the approximate amount of Stamp Duty Land Tax you'll need to pay when buying a property. Our stamp duty estimator gives you an accurate estimate based on current 2025 HMRC rates. The estimated stamp duty helps you budget for your property purchase alongside other costs like solicitor fees and surveys.

Stamp duty normally ranges from 0% to 12% depending on the property price. For an average UK house price of around £290,000, a standard buyer would pay approximately £4,000 in stamp duty, while a first-time buyer would pay £0 (as first-time buyers pay no stamp duty up to £300,000). Stamp duty charges increase significantly for properties over £925,000.

Stamp duty charges for additional properties include a 5% surcharge on top of standard rates. This means if you're buying a second home or buy-to-let property, you'll pay stamp duty starting at 5% from £0 (not £125,000). On a £300,000 property, additional property stamp duty would be £17,500 compared to £5,000 for a standard purchase.

You must pay stamp duty within 14 days of completing your property purchase. Your solicitor or conveyancer usually handles the stamp duty payment and SDLT return as part of the transaction process. Late payment can result in penalties and interest charges.

Yes, if you sell your previous main residence within 36 months of completing your new purchase, you can apply for a refund of the additional 5% surcharge. The refund must be claimed within 12 months of selling your old property or within 12 months of filing the SDLT return for the new property, whichever is later.

You qualify for first-time buyer relief if you've never owned an interest in a residential property in the UK or abroad, and the property price is £500,000 or less. If buying with someone else, both buyers must be first-time buyers to use the first-time buyer stamp duty rates.
