Stamp Duty Explained: UK Home Buyer Guide to SDLT, Rates and Reliefs

Category: Buying a Home > Home Buyers Guide > Stamp Duty

Stamp Duty Land Tax, also called SDLT, is a tax buyers may need to pay when buying property or land in England or Northern Ireland.

Simple answer: Stamp Duty is usually paid by the buyer after completion. The amount depends on the property price, buyer type, whether you already own another property, and whether you are a UK resident.

Stamp Duty can be one of the biggest hidden costs of buying a home, so buyers should check it before making an offer, before exchange of contracts and before completion.


What Is Stamp Duty?

Stamp Duty is a property tax paid when buying certain property or land. In England and Northern Ireland, it is officially called Stamp Duty Land Tax.

Most buyers hear about Stamp Duty when they receive a quote from their solicitor or mortgage adviser. However, it is better to check it much earlier, because it can affect your full buying budget.

Stamp Duty can apply to freehold houses, leasehold flats, buy-to-let properties, second homes and some shared ownership purchases.


Does Stamp Duty Apply Across the Whole UK?

No. Different parts of the UK use different property tax systems.

Location Property Tax Name
England Stamp Duty Land Tax, also called SDLT
Northern Ireland Stamp Duty Land Tax, also called SDLT
Scotland Land and Buildings Transaction Tax, also called LBTT
Wales Land Transaction Tax, also called LTT
Buyer tip: If you are buying in Scotland or Wales, do not use England and Northern Ireland SDLT rates. Use the correct Scottish or Welsh property tax guidance.

Stamp Duty at a Glance

Question Simple Answer
Who pays Stamp Duty? The buyer usually pays Stamp Duty, not the seller.
When is Stamp Duty paid? Usually after completion, within 14 days of completion.
Who normally files it? Your solicitor or conveyancer usually files the SDLT return and pays HMRC.

How Stamp Duty Is Calculated

Stamp Duty is usually calculated in bands. This means you do not normally pay one rate on the full property price. Instead, each rate applies only to the part of the price inside that band.

For example, if a home mover buys a main home for £450,000, the tax is worked out in portions.

Part of Price Rate Tax
First £125,000 0% £0
Next £125,000 2% £2,500
Remaining £200,000 5% £10,000
Total SDLT £12,500
Common mistake: Buyers sometimes think the highest rate applies to the full purchase price. Usually, SDLT is charged in bands.

Current Stamp Duty Rates for a Main Home

These standard SDLT rates usually apply when, after completion, the property is the only residential property you own.

Property Price Band SDLT Rate
Up to £125,000 0%
£125,001 to £250,000 2%
£250,001 to £925,000 5%
£925,001 to £1.5 million 10%
Above £1.5 million 12%

First-Time Buyer Stamp Duty Relief

First-time buyer Stamp Duty relief can reduce the amount of SDLT payable when buying your first home.

To qualify, all buyers must usually be first-time buyers. If you are buying with another person and one of you has owned property before, the relief may not apply.

First-Time Buyer Price Band SDLT Rate
Up to £300,000 0%
£300,001 to £500,000 5% on that portion
Above £500,000 First-time buyer relief does not apply
Example: If a first-time buyer purchases a home for £350,000, SDLT is charged at 5% on £50,000. The estimated SDLT would be £2,500.

Second Home and Buy-to-Let Stamp Duty

If buying a property means you will own more than one residential property, you may need to pay the higher rates of Stamp Duty. This is common for second homes, investment properties and buy-to-let purchases.

The higher rates can also be affected by property owned outside the UK, joint buyers, spouses or civil partners. Always check your own position before making an offer.

Additional Property Price Band Higher SDLT Rate
Up to £125,000 5%
£125,001 to £250,000 7%
£250,001 to £925,000 10%
£925,001 to £1.5 million 15%
Above £1.5 million 17%
Buyer warning: Additional property Stamp Duty can add thousands of pounds to your buying cost. Check it before you offer, not after your offer is accepted.

What If You Are Replacing Your Main Home?

If you are selling your current main residence and buying a new main residence, the higher additional property rate may not apply.

However, timing is important. If you complete on your new home before selling your old main residence, you may temporarily own two properties. In that case, you may need to pay the higher rate first and later check whether you can claim a refund.

Situation Possible Stamp Duty Result
You sell your old main home before or on the same day as buying the new one You may avoid the additional property rate.
You buy the new home before selling the old one You may pay higher rates first and later check refund rules.
You keep the old home as a rental or second property You will usually pay higher SDLT rates on the new purchase.

Non-UK Resident Stamp Duty Surcharge

If you are not a UK resident for SDLT purposes, you may need to pay an extra 2% non-resident Stamp Duty surcharge when buying residential property in England or Northern Ireland.

This can apply on top of standard SDLT rates, first-time buyer rates or additional property rates. Overseas buyers should get proper tax and legal advice before making an offer.

Important: Residency for SDLT can be different from everyday residency. Do not guess. Ask your solicitor or tax adviser to confirm.

Stamp Duty on Leasehold and Shared Ownership Homes

Stamp Duty can also apply to leasehold properties, including flats. For most leasehold purchases, SDLT is calculated mainly on the purchase price, also called the premium.

For some new leases, rent over the lease term may also be considered. Shared ownership properties can also have different SDLT options depending on how the purchase is structured.

Buyer tip: Leasehold and shared ownership Stamp Duty can be more complicated than a normal freehold purchase. Ask your conveyancer to explain the SDLT calculation clearly.

When Do You Pay Stamp Duty?

Stamp Duty is usually paid after completion. Your solicitor or conveyancer normally submits the SDLT return and pays HMRC using money you have provided.

The SDLT return and payment are usually due within 14 days of completion.

Buying Stage What Buyers Should Do
Before property search Understand whether Stamp Duty may apply to your budget.
Before making an offer Estimate your SDLT based on the offer price and buyer type.
Before exchange Ask your solicitor for the exact SDLT figure in the completion statement.
After completion Your solicitor normally files the SDLT return and pays HMRC.
