Stamp Duty Land Tax (SDLT) is a tax you pay when purchasing property or land in England and Northern Ireland above a certain threshold. The amount varies based on the property price, your buyer status, and whether you are a UK resident. Scotland and Wales have their own equivalent taxes — LBTT and LTT — with different rate bands.

How to Use the UK Stamp Duty Calculator
Buying a property in the UK comes with more than just the asking price. Stamp Duty Land Tax is one of the largest upfront costs and can add thousands of pounds to your purchase. This calculator helps you plan ahead by showing exactly how much stamp duty you will owe based on your property price, buyer status, and location.
Step 1: Enter the Property Price
Type in the full purchase price of the property in pounds. SDLT is calculated on a progressive band system — similar to income tax — so only the portion of the price within each band is taxed at that band's rate. A higher price means more of the purchase falls into higher tax bands.
Step 2: Select Your Buyer Type
Choose the option that best describes your situation. First-time buyers benefit from a relief that eliminates stamp duty on properties up to £425,000 and reduces it on properties up to £625,000. Home movers pay the standard rates. Additional property buyers (buy-to-let, second homes) face a 5% surcharge on all bands. Non-UK residents pay an extra 2% on top of the applicable rates.
Step 3: Choose the Property Location
The UK has three separate property tax systems. England and Northern Ireland use Stamp Duty Land Tax (SDLT). Scotland uses Land and Buildings Transaction Tax (LBTT) with different rate bands. Wales uses Land Transaction Tax (LTT) with its own thresholds. Select the correct location to get accurate figures.
Step 4: Review the Breakdown
The calculator shows your total stamp duty, the effective tax rate as a percentage, and the total purchase cost including tax. The band-by-band table shows exactly how much tax applies at each rate. The comparison table lets you see how much you would pay under different buyer types, helping you understand the financial impact of first-time buyer relief or the additional property surcharge.
Understanding the Rates
Stamp duty works on a tiered system. For example, on a £500,000 property purchase in England as a home mover, you pay 0% on the first £250,000, then 5% on the remaining £250,000 — totalling £12,500. If you were buying as an additional property, the 5% surcharge would apply to the entire purchase, adding £25,000 to bring the total to £37,500. These differences can significantly affect your budget, so it pays to calculate accurately before making an offer.

What is Stamp Duty Land Tax (SDLT)?
SDLT is a tax paid when you buy a property or land in England and Northern Ireland over a certain price. The amount depends on the purchase price and whether you are a first-time buyer, home mover, or buying an additional property.
Do first-time buyers pay stamp duty?
First-time buyers in England and NI pay no SDLT on properties up to £425,000. For properties between £425,001 and £625,000, they pay 5% on the portion above £425,000. Properties over £625,000 do not qualify for first-time buyer relief.
What is the additional property surcharge?
If you are buying an additional property such as a buy-to-let or second home, you pay a 5% surcharge on top of the standard SDLT rates on the entire purchase price. This applies to properties costing more than £40,000.
How is stamp duty different in Scotland and Wales?
Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT). Both have their own rate bands that differ from England's SDLT. This calculator covers all three systems.
Do non-UK residents pay extra stamp duty?
Yes, non-UK residents pay a 2% surcharge on top of the applicable SDLT rates when buying residential property in England and Northern Ireland. This surcharge applies in addition to any other surcharges such as the additional property supplement.
Are the stamp duty rates in this calculator up to date?
This calculator uses the SDLT rates effective from April 2025. Tax rates can change in government budgets, so always verify with HMRC or a solicitor for the most current rates before completing a purchase.
