Understanding Stamp Duty Land Tax

Stamp Duty Land Tax (SDLT) is a tax paid when you buy a property in England or Northern Ireland. Scotland and Wales have their own systems: Land and Buildings Transaction Tax (LBTT) in Scotland and Land Transaction Tax (LTT) in Wales. This calculator helps you understand the exact tax you'll owe based on your property price and circumstances.

England & Northern Ireland SDLT Rates (2025/26)

Standard buyer (second property onwards):

• £0 to £250,000: 0%
• £250,001 to £925,000: 5%
• £925,001 to £1,500,000: 10%
• £1,500,000+: 12%

First-Time Buyer Relief (2025/26):

• £0 to £425,000: 0%
• £425,001 to £550,000: 5%
• £550,001+: Standard rates apply

Additional Property Surcharge: Properties that are not your main residence (buy-to-let, second homes) are subject to a 5% additional surcharge on top of standard rates. This makes a £300,000 property cost 10% SDLT (5% + 5% surcharge) instead of 5%.

Scotland: Land and Buildings Transaction Tax (LBTT) Rates

LBTT uses different bands and rates than England. Current rates (2025/26):

• £0 to £145,000: 0%
• £145,001 to £250,000: 2%
• £250,001 to £325,000: 5%
• £325,001 to £750,000: 10%
• £750,001+: 12%

Scotland also offers first-time buyer relief up to £175,000 (0% tax). The relief extends to properties worth up to £350,000 with a sliding scale.

Wales: Land Transaction Tax (LTT) Rates

Wales introduced its own tax system with these bands (2025/26):

• £0 to £225,000: 0%
• £225,001 to £400,000: 6%
• £400,001 to £750,000: 7.5%
• £750,001 to £1,500,000: 10%
• £1,500,001+: 12%

Wales also provides first-time buyer relief on properties up to £425,000.

When Do You Pay Stamp Duty?

You must pay stamp duty within 14 days of completion of your property purchase. You typically pay it to HMRC before your solicitor registers the property with the Land Registry. If you miss this deadline, you'll incur penalties and interest charges.

Key Stamp Duty Exemptions & Reliefs

First-Time Buyer Relief: If you've never owned a property (or haven't in the past 3 years), you may qualify for relief on properties up to £425,000 in England, £175,000 in Scotland, or £425,000 in Wales.

Multiple Relief: If you're buying a new main residence while still owning another property, you may get a partial refund after selling your old home within 3 years.

Disadvantaged Area Relief: Some rural and economically disadvantaged areas offer full SDLT relief on purchases up to £500,000.

Right-to-Buy: Council tenants buying their home under Right-to-Buy schemes get SDLT relief.

Freehold Enfranchisement: Buying the freehold on your flat (leaseholders only) is SDLT-free.

Additional Property Surcharge Explained

If you already own a property and buy another (e.g., buy-to-let, holiday home, student accommodation), you pay an extra 5% surcharge on top of standard SDLT rates. On a £300,000 property, the surcharge adds £15,000 to your stamp duty bill. This was introduced to discourage investment in the housing market and protect first-time buyers. The surcharge applies to non-UK residents as well.

Common Questions About Stamp Duty

Can I avoid stamp duty? Only through exemptions like first-time buyer relief, disadvantaged area relief, or right-to-buy schemes. If you're not eligible, you must pay. Don't attempt to artificially split the purchase price to avoid tax—this is illegal.

Do I pay stamp duty on a mortgage? No. Stamp duty is paid on the property price, not your mortgage. It's a separate cost you must budget for when buying.

What if I miss the deadline? Penalties start at 5% of the unpaid tax and rise to 10% if still unpaid after 12 months. Interest is also charged. Always pay on time.

Is there relief if I buy and sell within a short timeframe? Yes, multiple relief allows you a refund if you sell your old main residence within 3 years of buying a new one. You must apply within 12 months of the sale.
