Stamp duty on second homes is one of the largest extra costs facing anyone who buys an additional property in England or Northern Ireland. If you already own a home and buy another — as a holiday home or a buy-to-let investment — you will normally pay Stamp Duty Land Tax (SDLT) at rates 5 percentage points above the standard residential bands. On a £300,000 purchase, that surcharge alone adds £15,000 to the tax bill. This guide explains the current rates, shows worked examples, and sets out the main exceptions.
What Is Stamp Duty on Second Homes?
Stamp Duty Land Tax is paid by the buyer when land or property is bought in England or Northern Ireland. The standard rates apply when you buy your only home; the higher rates apply when the purchase leaves you owning more than one residential property.
The stamp duty on second homes rules are wider than the name suggests. They can catch a buy-to-let flat, a holiday cottage, or even a share in another property worth £40,000 or more. What matters is your ownership position when you complete, not what you plan to use the property for. Scotland and Wales have separate systems, so this guide covers England and Northern Ireland only.
Current SDLT Rates for Second Homes
The stamp duty on second homes surcharge rose from 3% to 5% on 31 October 2024, and the standard bands below have applied since 1 April 2025. The higher rates add 5 percentage points to every standard band, and SDLT is charged on a slice basis, so each rate applies only to the part of the price inside that band. Rates are current at the time of writing and can change, so check GOV.UK before you complete.
| Portion of the purchase price | Standard rate | Second home / buy-to-let rate |
|---|---|---|
| Up to £125,000 | 0% | 5% |
| £125,001 to £250,000 | 2% | 7% |
| £250,001 to £925,000 | 5% | 10% |
| £925,001 to £1,500,000 | 10% | 15% |
| Above £1,500,000 | 12% | 17% |
Worked Example: Stamp Duty on a £300,000 Second Home
The following worked example shows how the figures add up for an additional residential property costing £300,000:
- First £125,000 at 5% = £6,250
- Next £125,000 at 7% = £8,750
- Remaining £50,000 at 10% = £5,000
- Total SDLT = £20,000
The same property as an only home would cost £5,000 at the standard rates, so the surcharge adds £15,000 here. For a £500,000 buy-to-let, the total would be £40,000 at the higher rates, against £15,000 at the standard rates. These examples assume a UK-resident buyer, no reliefs, and an ordinary residential purchase. For a detailed breakdown, see the guide to stamp duty on a second home.
When Does Stamp Duty on Second Homes Apply?
The higher rates normally apply where the property costs £40,000 or more and you own or part-own another residential property worth at least £40,000 when you complete. Several points catch buyers out:
- Joint purchases. If the higher rates apply to any one joint buyer, they normally apply to the whole transaction.
- Married couples and civil partners. Couples living together are normally treated as one unit, so if either partner triggers the higher rates, the whole purchase can be charged at the higher rates even if only one name is on the deeds.
- Overseas property counts. Owning a home abroad can trigger the higher rates on a UK purchase, because HMRC looks at residential property ownership anywhere in the world.
- Companies. A company buying residential property normally pays the higher rates on any purchase of £40,000 or more.
- Non-UK residents. An extra 2% surcharge can apply on top of the higher rates.
First-time buyer relief, which gives 0% SDLT on the first £300,000 of a purchase up to £500,000, is not available on a second home.
Replacing Your Main Residence and the 3-Year Refund
The most important exception covers people who are simply moving home. If you sell your previous main residence before completing on the new one, the higher rates do not normally apply — even if you still own a separate buy-to-let property.
If you buy first, you pay the higher rates at completion and can claim the extra back, provided the new property becomes your main residence and you sell your previous main residence within three years. The refund claim must normally reach HMRC by the later of 12 months after the sale of the previous main residence, or 12 months after the filing date of the SDLT return for the new property — missing that deadline can put the refund at risk.
Buy-to-Let Property: Extra Points for Landlords
Buying a property to let brings tax questions beyond the SDLT bill. Rental income is taxable and must be reported, and landlords with qualifying income over £50,000 come within Making Tax Digital for Income Tax from April 2026. Allowable expenses and mortgage interest relief at the basic rate also affect the return, so model the running tax cost as well as the one-off SDLT.
When you later sell a buy-to-let property, Capital Gains Tax may apply to the gain. Private Residence Relief can reduce or remove the gain on a home that was your main residence, but it does not normally shelter a property let throughout your ownership. Any CGT due on a UK residential property disposal must usually be reported and paid within 60 days of completion. Property held long term can also affect your estate, so it is worth understanding how Inheritance Tax treats property you own.
How and When to Pay SDLT
Your solicitor or conveyancer will normally handle the SDLT return, but the legal responsibility sits with you as the buyer. The return must be filed and the tax paid within 14 days of the effective date of the transaction, which is usually the completion date. Late filing can lead to penalties and interest, so confirm with your conveyancer that the return has been submitted. Keep the SDLT Unique Transaction Reference Number, as you will need it to claim any refund of the higher rates.
