Stamp Duty on a Second Home: The 5% Surcharge and When You Can Reclaim It

If you buy an additional residential property in England or Northern Ireland for £40,000 or more, you pay a 5% stamp duty surcharge on top of the standard SDLT rates, charged on the whole purchase price. Scotland charges 8% Additional Dwelling Supplement (ADS) and Wales uses a separate higher-rates table. The surcharge can be reclaimed in full if the purchase was actually replacing your main home and you sell the old one within three years.

• The surcharge applies if you own an interest in another dwelling anywhere in the world at the end of the day you complete, and you are not replacing your only or main residence.
• In England and Northern Ireland the extra is 5 percentage points on every band, so a £350,000 second home costs £25,000 instead of £7,500.
• Married couples and civil partners are treated as one buyer — you cannot sidestep the surcharge by buying in one name.
• If you bought before selling your old main home, you can reclaim the surcharge once the old home sells, provided that happens within three years.
• Scotland's ADS is 8% and Wales has its own higher rates that reach 17% at the top.

Who pays the second home surcharge

The higher rates are not really about "second homes" in the holiday-cottage sense. The test is mechanical: at the end of the day you complete, do you own a major interest in two or more dwellings, and is the new one not a replacement for your main residence? If the answer to both is yes, the surcharge applies.

That catches far more people than expected, including:

• Buy-to-let landlords buying their first rental while owning the home they live in.
• Someone who keeps their old flat and rents it out when they move.
• A homeowner buying a holiday home or a property for a family member.
• Anyone who already owns property abroad and is buying their first UK home — an overseas dwelling counts.
• Parents going on the deeds of a child's purchase, because the surcharge is judged on the whole price if any buyer owns another dwelling.

The £40,000 rule

Two separate £40,000 tests matter. First, the surcharge only applies if the property you are buying costs £40,000 or more. Second, when HMRC counts the property you already own, an interest worth less than £40,000 is ignored — so a tiny share in a low-value property does not automatically drag you into the higher rates.

What counts as a dwelling

Caravans, mobile homes and houseboats are excluded. A share in a property you inherited within the last three years is ignored in England and Northern Ireland if that share is 50% or less. Leases with less than 21 years left to run are also disregarded. A self-contained annexe within the grounds of the main house can be treated as part of the main dwelling rather than a separate one where it meets the subsidiary dwelling conditions.

First-time buyer relief and the surcharge are mutually exclusive. If you own or have ever owned a dwelling anywhere in the world you are not a first-time buyer, which is covered in more detail in our guide to stamp duty for first-time buyers in 2026.

Second home stamp duty rates in 2026

In England and Northern Ireland the higher rates are the standard rates plus five percentage points in every band, including the nil-rate band. In practice that means you calculate normal SDLT and then add 5% of the full purchase price.

Worked example — £350,000 second home in England. Standard SDLT is nothing on the first £125,000, 2% on the next £125,000 (£2,500) and 5% on the final £100,000 (£5,000) — £7,500 in total. The surcharge adds 5% of £350,000, which is £17,500. Total due: £25,000, payable within 14 days of completion.

Scotland and Wales

Scotland charges LBTT plus the Additional Dwelling Supplement at 8% of the whole price where the purchase is £40,000 or more. Wales does not bolt a surcharge on top; it applies a completely separate higher-rates table starting at 5% from the first pound.

The Scottish figure is built from LBTT of £2,100 (2% on £145,000–£250,000), £3,750 (5% on £250,000–£325,000) and £2,500 (10% on £325,000–£350,000), giving £8,350, plus ADS of £28,000. The Welsh figure is £9,000 (5% on the first £180,000), £5,950 (8.5% on the next £70,000) and £10,000 (10% on the final £100,000).

Two further add-ons exist in England and Northern Ireland. Non-UK residents pay a further 2% on top of the higher rates, and companies buying a single dwelling above £500,000 can face a flat punitive rate unless a relief such as property rental business relief applies. You can compare any price and any scenario in the second home stamp duty calculator.

Replacing a main home: the big exception

You do not pay the surcharge simply because you own two properties on completion day. The higher rates are switched off where the new property replaces your only or main residence. To qualify in England and Northern Ireland you must:

1. Be buying a property you intend to live in as your only or main residence; and
2. Have sold your previous main residence in the three years before the purchase; and
3. Have actually lived in that previous property as your main residence at some point in those three years.

If the sale completes on or before the day you buy, the surcharge never applies — even if you own five buy-to-lets. Owning other property is irrelevant as long as the chain of main residences is unbroken.

Problems start when the sale slips. If you complete on the new home before the old one sells, you own two dwellings at the end of the day and the surcharge is due in full. It is not optional and it is not deferred: you pay it, then reclaim.

The three-year refund

Sell your previous main residence within three years of buying the new one and you can claim the entire surcharge back. HMRC repays the difference between what you paid and what the standard rates would have produced.

Worked example. You buy a £450,000 house to live in while your old home is still on the market. Standard SDLT is £2,500 (2% on £125,000–£250,000) plus £10,000 (5% on £250,000–£450,000) = £12,500. The surcharge adds 5% of £450,000 = £22,500, so you pay £35,000 at completion. Fourteen months later the old home sells. You claim and HMRC refunds the £22,500, leaving £12,500 — exactly what you would have paid had the sale gone through first.

How and when to claim

In England and Northern Ireland you claim through HMRC's repayment of higher rates of Stamp Duty Land Tax service. You need the UTRN from the original SDLT return, both completion dates and the amount of tax paid. The deadline is the later of 12 months from the date you sold the old main residence and 12 months from the filing date of the SDLT return on the new home. Miss it and the money is gone, so the claim should follow the sale quickly rather than wait.

In Scotland the ADS reclaim window was extended to 36 months for transactions from 1 April 2024, and the claim is made by amending the original LBTT return with Revenue Scotland. In Wales the Welsh Revenue Authority operates a three-year disposal window with a similar 12-month claim deadline.

One point catches people out: the three years run from the purchase, not from when the property was listed. Exceptional delays outside your control — a blocked sale, for example — can sometimes be accepted late, but this is discretionary rather than automatic.

Married couples and civil partners

For surcharge purposes, spouses and civil partners living together are treated as a single unit. If either of you owns another dwelling, a purchase by either of you attracts the surcharge, even if the buyer's name on the deeds is only one of you and the mortgage is in one name too. The same applies to the replacement rule: the property you sold must have been the couple's main residence.

There is one meaningful exception. If you are permanently separated — under a court order, a formal deed of separation, or in circumstances where the separation is likely to be permanent — you stop being treated as one unit. That matters in divorce, where one partner buys a new home while the former matrimonial home is still jointly owned.

Unmarried couples are assessed individually, but joint purchases are not helped by this: if any single buyer owns another dwelling, the higher rates apply to the whole price, not to their share.

Is there a second home loophole?

There is no clean way to avoid stamp duty on a second home, and the arrangements marketed as loopholes usually fail or cost more than they save. What genuinely exists in the legislation:

• Purchases under £40,000 fall outside the surcharge entirely and generally need no return.
• Mixed-use property — a flat above a shop, say — is charged at non-residential rates with no surcharge, but HMRC challenges weak claims hard.
• Six or more dwellings in one transaction can be treated as non-residential. Multiple Dwellings Relief was abolished for transactions from 1 June 2024, so that route has closed.
• Timing the sale so the old main home completes on or before the new purchase avoids the surcharge upfront and is the only reliable planning most buyers have.
• Buying through a company does not help: companies pay the surcharge from the first pound and face the corporate flat rate above £500,000.

Firms offering contingent-fee "reclaim" services for purchases that were never main-residence replacements are a known risk area. If HMRC opens an enquiry the tax, interest and any penalty land on the buyer, not the adviser.

What to do next

Work out the real cost before you commit to an offer. Run the price through the second home stamp duty calculator to see the surcharge for your nation, then compare it with the standard figure in the stamp duty calculator — the gap is the amount you could reclaim if the purchase turns out to be a delayed main-home replacement. If you are buying your first property and only own something overseas, read the 2026 first-time buyer stamp duty guide before assuming relief applies.
