Calculate Stamp Duty Land Tax (SDLT) on a UK property purchase, including first-time buyer relief and the additional property surcharge.
2025 SDLT bands for England & Northern Ireland (example)
This calculator estimates Stamp Duty Land Tax (SDLT) — the tax payable when buying property or land in England and Northern Ireland — based on the property price, whether you're a first-time buyer, and whether the property is an additional property (such as a second home or buy-to-let). SDLT is calculated using a banded structure, similar to Income Tax, where different portions of the price are taxed at different rates.
SDLT uses a banded (marginal) structure: each portion of the property price falling within a band is taxed at that band's rate, similar to how Income Tax bands work. First-time buyers get different, more generous bands up to a certain price threshold. An additional property surcharge, if applicable, is calculated as a flat percentage of the entire property price and added on top of the base tax.
Formula: For each band, Tax in Band = (min(Price, Band Upper Limit) − Band Lower Limit) × Band Rate, summed across all applicable bands = Base Tax. Surcharge = Price × Additional Property Rate (if applicable). Total SDLT = Base Tax + Surcharge. Effective Rate = (Total SDLT ÷ Price) × 100.
Example (using example 2025 bands): A £300,000 property purchase by a buyer who isn't a first-time buyer and isn't buying an additional property falls into the 0% band up to £125,000 (£0 tax), the 2% band from £125,000-£250,000 (£2,500 tax on £125,000), and the 5% band from £250,000-£925,000 (£2,500 tax on the remaining £50,000) — giving a total SDLT of £5,000, an effective rate of about 1.67%. A first-time buyer purchasing the same £300,000 property would pay £0 SDLT, as the first-time buyer relief band covers the full price up to £300,000 at 0%. (Note: bands and rates used in this example are illustrative — always check current HMRC SDLT rates, as these are reviewed and changed periodically.)
Stamp Duty Land Tax applies to property and land purchases in England and Northern Ireland — Scotland has its own Land and Buildings Transaction Tax (LBTT) and Wales has its own Land Transaction Tax (LTT), both with different bands and rates, so this calculator's bands (designed for England & NI) won't apply if you're buying in Scotland or Wales. SDLT bands and rates are set by the UK government and have been changed multiple times in recent years, including temporary changes during economic events — always check the current HMRC SDLT rates for the date of your purchase, as the rates used in this calculator are illustrative examples. First-time buyer relief offers reduced or zero SDLT on properties up to a certain value, intended to help people get onto the property ladder, but this relief typically doesn't apply above a certain price ceiling, and you must not have owned property anywhere in the world previously to qualify. The additional property surcharge applies an extra percentage on top of standard rates for buyers purchasing a second home, buy-to-let property, or other additional residential property — this can add a substantial amount to the SDLT bill and is a key consideration for landlords and second-home buyers. SDLT is normally due within a set number of days of completion, and is typically handled by your conveyancing solicitor as part of the purchase process.
No. This calculator uses Stamp Duty Land Tax (SDLT) bands, which apply to England and Northern Ireland only. Scotland has its own Land and Buildings Transaction Tax (LBTT), and Wales has its own Land Transaction Tax (LTT) — both have different bands and rates, so this calculator wouldn't give an accurate result for properties in those nations.
Generally, you must never have owned a residential property anywhere in the world before (either on your own or with someone else), and you must be buying the property as your only or main residence. First-time buyer relief usually only applies up to a certain property price — above that ceiling, standard rates may apply to the whole price. Check current HMRC rules for the exact criteria and price thresholds.
If you're buying a property that will be an additional property (such as a second home, holiday home, or buy-to-let) rather than replacing your main residence, an extra percentage surcharge (example rate — check current HMRC rules) is added on top of the standard SDLT rates, calculated on the entire purchase price. This can add a significant amount to the total SDLT owed.
SDLT is normally due within a set number of days of completing the property purchase (commonly handled and filed by your conveyancing solicitor as part of the transaction). The buyer is responsible for paying SDLT — it's not paid by the seller.
The bands used here are illustrative examples based on a recent SDLT structure. UK governments have changed SDLT rates and thresholds multiple times in recent years, including temporary reductions during certain periods. Always check the current rates on HMRC's website or with your solicitor before relying on a figure for an actual purchase.
Generally, if you're replacing your main residence (selling your previous main home, even if the sale completes after the purchase, subject to time limits for reclaiming any surcharge paid), the additional property surcharge typically doesn't apply to the new main home. However, if you temporarily own two properties, you may need to pay the surcharge upfront and then reclaim it once your previous home is sold, within a specified time limit. Check current HMRC guidance for the exact rules and time limits.
