How Stamp Duty Works in the UK

Stamp duty is a tax levied on property purchases in the UK. The amount you pay depends on where you are buying, the purchase price, and your circumstances as a buyer. Each nation within the UK has its own system:

England & NI

SDLT — Stamp Duty Land Tax. Applies progressive rates with nil-rate band up to £125,000. First-time buyers get relief up to £300,000.

Scotland

LBTT — Land and Buildings Transaction Tax. Nil-rate band up to £145,000 (£175,000 for first-time buyers). ADS of 6% on additional properties.

Wales

LTT — Land Transaction Tax. Nil-rate band up to £225,000 for main residences. No first-time buyer relief. Higher rates for additional properties.

All three systems use a progressive band structure, meaning you only pay the higher rate on the portion of the price that falls within each band — not on the entire purchase price. This is similar to how income tax works.

On top of standard rates, additional property surcharges apply when purchasing a second home or buy-to-let investment. And in England & Northern Ireland, non-UK residents face an additional 2% surcharge on all applicable rates.

Stamp Duty FAQs

Common questions about stamp duty, SDLT, LBTT, and LTT answered by our team.

What is stamp duty land tax (SDLT)?

Stamp Duty Land Tax (SDLT) is a tax you pay when you buy a property or land in England or Northern Ireland above a certain price threshold. The amount you pay depends on the purchase price, your buyer status (first-time buyer, next home, or additional property), and whether you are a UK resident. Scotland and Wales have their own equivalent taxes: Land and Buildings Transaction Tax (LBTT) and Land Transaction Tax (LTT) respectively.

How much is stamp duty for first-time buyers?

In England and Northern Ireland, first-time buyers pay no SDLT on properties up to £300,000. For properties between £300,001 and £500,000, first-time buyers pay 5% on the portion above £300,000. If the property costs more than £500,000, first-time buyer relief does not apply and standard rates must be used. In Scotland, first-time buyers benefit from an increased nil-rate band of £175,000. Wales does not offer first-time buyer relief on Land Transaction Tax. Most UK lenders require a minimum deposit of 5% of the property value, giving you a 95% loan-to-value (LTV) mortgage. However, a larger deposit typically unlocks lower interest rates. A 10% deposit often reduces your rate significantly, and a 25% deposit or more gives you access to the most competitive deals.

Do I pay stamp duty on a buy-to-let property?

Yes, buy-to-let properties are classified as additional properties and attract the higher stamp duty rates. In England and Northern Ireland, this means a 5% surcharge on top of each standard rate band. In Scotland, the Additional Dwelling Supplement (ADS) adds 6% on the entire purchase price. In Wales, higher residential rates apply starting from 5% on the first band. These higher rates apply even if the buy-to-let is your only property but is not your main residence.

How does the additional property surcharge work?

The additional property surcharge applies when you buy a property in addition to your main residence, such as a second home or buy-to-let investment. In England and Northern Ireland, a 5% surcharge is added to each standard SDLT band. In Scotland, the Additional Dwelling Supplement (ADS) charges 6% on the entire purchase price on top of the standard LBTT. In Wales, a separate set of higher residential rates applies, starting at 5% for the first band instead of 0%.

What is the non-UK resident stamp duty surcharge?

Non-UK residents purchasing property in England or Northern Ireland must pay a 2% surcharge on top of the standard SDLT rates. This applies to individuals who are not present in the UK for at least 183 days in the 12 months before the purchase. The surcharge applies in addition to any other surcharges, such as the additional property surcharge, meaning a non-UK resident buying a buy-to-let property could face both the 5% additional property surcharge and the 2% non-UK resident surcharge.

Is stamp duty different in Scotland and Wales?

Yes. Scotland uses Land and Buildings Transaction Tax (LBTT) instead of SDLT, with different thresholds and rates. The nil-rate band starts at £145,000 (or £175,000 for first-time buyers). Wales uses Land Transaction Tax (LTT), with a nil-rate band of £225,000 for main residences. Both systems operate on a progressive band structure similar to SDLT, but the thresholds and rates differ. Neither Scotland nor Wales currently applies a non-UK resident surcharge.

Can I reduce my stamp duty bill?

There are limited ways to reduce your stamp duty liability legitimately. First-time buyer relief can eliminate or reduce SDLT for eligible purchasers. If you are replacing your main residence and have sold your previous home, you may avoid the additional property surcharge. Some purchases, such as certain types of commercial property or transactions below the nil-rate threshold, may attract lower or no stamp duty. Always consult a property tax specialist for advice specific to your situation.

When do I pay stamp duty?

Stamp duty must be paid within 14 days of the effective date of the property transaction, which is usually the completion date. In practice, your conveyancer or solicitor will normally handle the SDLT return and payment on your behalf as part of the conveyancing process. The 14-day deadline applies to SDLT in England and Northern Ireland, LBTT in Scotland, and LTT in Wales. Late filing or payment can result in penalties and interest charges.

Does stamp duty apply to remortgages?

No, stamp duty does not apply to remortgages. SDLT, LBTT, and LTT are only payable when you purchase a property or land. If you are simply switching your mortgage to a different lender or changing your mortgage deal with the same lender, no stamp duty is due. Stamp duty only becomes relevant again if you are purchasing a new property or transferring ownership.

What happens if I am replacing my main residence?

If you are buying a new main residence and have sold or will sell your previous main residence within 3 years, the additional property surcharge does not apply. However, if you complete the purchase of your new home before selling your old one, you will initially pay the higher rates. You can then claim a refund of the surcharge from HMRC within 3 months of selling your previous main residence, as long as the sale happens within 3 years of the new purchase.
