Second Home Stamp Duty
The complete guide to the 5% additional property surcharge.
Key Takeaways
- A £400,000 second home now costs £30,000 in SDLT (7.5% effective rate) compared to £10,000 for a main residence. The 5% surcharge adds £20,000 to the purchase price.
- Joint ownership with someone who already owns a property triggers the surcharge for both buyers. Even if one buyer is a first-time purchaser, the entire purchase attracts the additional 5%.
- Divorce settlements where a spouse receives property under a court order are exempt from the surcharge. This applies even if the receiving spouse already owns another property.
- Properties purchased through a company always pay the surcharge, with no 36-month refund option. Corporate ownership eliminates the replacement main residence relief available to individuals.
- The effective date for determining ownership is exchange of contracts, not completion. Owning property on exchange day triggers the surcharge even if you sell before completing.
- Wales's separate LTT higher rate structure means a £750,000 second home costs £61,875 in Wales vs £65,000 in England. Welsh rates can be slightly cheaper at certain price points.
- Non-UK residents buying a second home pay 7% on the first £125,000 (5% additional property + 2% non-resident). This compounds to create significantly higher total SDLT bills.

What is the Second Home Surcharge?
The additional property surcharge (commonly called the "second home surcharge") is an extra 5% stamp duty charged on the purchase of additional residential properties. Use our second home calculator for your exact cost.
The surcharge was introduced in April 2016 at 3% and increased to 5% in April 2025. It applies to the entire purchase price, not just portions above certain thresholds.
5% Surcharge Explained
The 5% surcharge is not a flat additional tax on top of standard rates. Instead, it's added to the rate charged on each band of the purchase price.
Here's how it works in practice:
- First £125,000: Standard 0% + 5% surcharge = 5% total
- £125,001 - £250,000: Standard 2% + 5% surcharge = 7% total
- £250,001 - £925,000: Standard 5% + 5% surcharge = 10% total
- £925,001 - £1,500,000: Standard 10% + 5% surcharge = 15% total
- Over £1,500,000: Standard 12% + 5% surcharge = 17% total
Important: The surcharge was increased from 3% to 5% in October 2024. See our April 2025 second home rates guide for the full picture. This means buyers purchasing second homes since October 2024 pay significantly more than those who bought before this date.
What Counts as an 'Additional' Property?
A property is considered "additional" if, at the end of the day you complete the purchase, you own two or more residential properties worth £40,000 or more.
This includes:
- Any residential property you already own in the UK
- Residential property you own anywhere else in the world
- Inherited properties where you own 50% or more
- Properties you have a beneficial interest in (e.g., through a trust)
- Mixed-use properties with a residential element
The £40,000 Rule
Properties worth less than £40,000 are ignored when determining if the surcharge applies. However, this threshold is rarely relevant in practice - most residential properties exceed £40,000 in value. Caravans, mobile homes, and houseboats can sometimes fall below this threshold.
Replacing Your Main Residence
You can avoid the surcharge entirely if you're replacing your main residence. See our replacement main residence guide for full eligibility. To qualify, you must:
- Intend for the new property to be your only or main residence
- Be selling (or have already sold) your previous main residence
- Have occupied the previous property as your main residence at some point in the 3 years before completion
If you've already sold your old home before buying the new one, the surcharge doesn't apply at all. If you buy the new home before selling the old one, you'll pay the surcharge initially but can claim it back later (see 3-Year Refund Window below).
3-Year Refund Window
How the Refund Works
If you buy a new main residence before selling your old one, you'll pay the 5% surcharge on completion. However, if you sell your previous main residence within 36 months (3 years), you can claim a full refund of the surcharge amount. Our refund guide explains the process step-by-step.
You must claim the refund within 12 months of selling your old property, or 12 months from filing your SDLT return (whichever is later). Claims are made by amending your original SDLT return.
Example scenario: You buy a £400,000 new home on 1 March 2025 while still owning your old home. You pay £30,000 stamp duty (includes the 5% surcharge = £20,000 extra). You sell your old home on 1 December 2026 (21 months later). You can claim back the £20,000 surcharge, reducing your total stamp duty to £10,000.
Married Couples and Joint Ownership
Treated as One Unit
Married couples and civil partners are treated as a single unit for stamp duty purposes. If eitherspouse owns another property, the surcharge applies to purchases made by either or both of you.
This means:
- If your spouse owns a buy-to-let, you can't buy a "main residence" without the surcharge
- Property owned before marriage counts towards the surcharge after marriage
- Separation doesn't automatically end this rule - you remain treated as one unit until divorce is finalized
- The rule applies even if only one name appears on the new property's title deed
Exception: If you're legally separated or in divorce proceedings, you may be able to claim exemption from this rule, but you'll need professional advice and proper documentation.
Holiday Homes and Inherited Properties
Holiday Homes
Holiday homes and second homes purchased for personal use (not rental) trigger the 5% surcharge in full. There's no exemption for properties you don't intend to rent out. The surcharge applies whether you plan to use the property for weekends, holidays, or leave it empty.
Inherited Properties
Inherited properties affect the surcharge differently depending on your ownership share:
- Less than 50% share: Ignored for surcharge purposes (doesn't trigger surcharge on other purchases)
- 50% or more: Counts as an additional property, triggering the surcharge on future purchases
- Inherited within 3 years: Special rules may apply if you inherited less than 50% within 3 years of purchase
Example: You inherit a 25% share of your parents' property worth £300,000. This doesn't trigger the surcharge when you buy your own home. However, if you inherit 60% of the same property, it counts as an additional property, and any future residential purchase will attract the 5% surcharge.
Worked Example: £350,000 Second Home vs Primary Residence
Here's the exact calculation showing the difference between buying a £350,000 property as your main residence versus as a second home:
Primary Residence (No Surcharge)
Second Home (With 5% Surcharge)
Extra cost for second home: £17,500 (more than double the standard rate)
The 5% surcharge adds £17,500 to the stamp duty bill on a £350,000 second home. This represents a 233% increase compared to buying the same property as a main residence.
Second Home SDLT Rates

| £750,000 | £27,500 | £65,000 | +£37,500 |
When Does the Surcharge Apply?
The surcharge applies if, at the end of the day of purchase, you will own two or more residential properties and you're not replacing your main residence.
The Surcharge DOES Apply To:
- ✓ Second homes and holiday homes
- ✓ Buy-to-let investment properties
- ✓ Properties bought by companies (though corporate buyers may face the higher 17% rate instead)
- ✓ Buying a new home before selling your old one
- ✓ Properties where you have a beneficial interest over 50%
- ✓ Purchases by non-resident buyers (who also pay the additional 2% non-resident surcharge)
The £40,000 Threshold
The surcharge only applies to properties costing more than £40,000. Properties below this threshold don't attract the surcharge (though they still count as "additional properties" when assessing other purchases).
Replacement Main Residence
You can avoid the surcharge if you're replacing your main residence and selling your previous main home. The key conditions are:
- The new property will be your main residence
- You're selling (or have sold) your previous main residence
- The previous property was your main residence at some point in the 3 years before buying
The 36-Month Refund Rule
Claim Back the Surcharge
If you paid the surcharge because you bought a new home before selling your old one, you can claim a refund if you sell your previous main residence within the 36-month window.
Time limit: You must claim within 12 months of selling your old property, or within 12 months of filing your SDLT return (whichever is later).
Inherited Property
Inheriting a property can trigger the surcharge on future purchases, but there are important rules:
- Less than 50% share: If you inherit less than 50% of a property, it's ignored for surcharge purposes
- 50% or more: If you inherit 50% or more, it counts as an additional property
- 3-year rule: Inherited property is ignored if you inherited it within 3 years of buying and have a share of less than 50%
Married Couples
Important: Spousal Ownership
Married couples and civil partners are treated as a single unit. If either spouse owns another property, both are considered to own it for surcharge purposes. This applies even if only one person is buying the new property.
Property Abroad
The surcharge considers property ownership worldwide. If you own residential property in another country, it counts as an additional property for UK stamp duty purposes.
Scotland and Wales
Scotland charges the Additional Dwelling Supplement (ADS) on second home purchases at 8%, higher than England's 5% surcharge.
| Region | Surcharge Rate | Name |
|---|---|---|
| England & NI | 5% | Higher Rates for Additional Dwellings |
| Scotland | 8% | Additional Dwelling Supplement (ADS) |
| Wales | Separate bands (from 5%) | Higher Rates |
Frequently Asked Questions About Second Home Stamp Duty
How much extra stamp duty do I pay on a second home?
You pay an additional 5% on top of all standard stamp duty rates when buying a second home. This applies to the entire purchase price, not just higher bands. For example, on a £300,000 second home, the 5% surcharge adds £15,000 to your stamp duty bill (from £5,000 standard to £20,000 total). The surcharge increased from 3% to 5% in October 2024, significantly increasing costs for second home buyers.
Can I avoid the second home surcharge?
Yes, in certain circumstances. The surcharge doesn't apply if you're replacing your main residence - meaning you're selling your previous home and buying a new one to live in. If you buy the new home before selling the old one, you'll pay the surcharge initially but can claim a full refund if you sell your previous main residence within 36 months (3 years). The refund must be claimed within 12 months of selling your old property.
Do I pay the surcharge if I own a property abroad?
Yes. The surcharge applies if you own any residential property anywhere in the world worth £40,000 or more. This includes holiday homes in Spain, inherited apartments in Poland, family properties in India, or any other country. When you buy a UK property while owning property abroad, HMRC treats it as an additional property purchase, triggering the 5% surcharge. The worldwide property rule is strictly enforced.
What if I'm replacing my main residence?
If you're selling your current main residence and buying a new one to replace it, you can avoid the surcharge. The key conditions are: (1) the new property must be your intended main residence, (2) you must be selling your previous main residence, and (3) you lived in the previous property as your main home at some point in the 3 years before completion. If you buy before selling, you'll pay the surcharge but can reclaim it within 36 months of purchase if you sell the old property within that time.
How do I claim back the second home surcharge?
You claim the refund by amending your original SDLT return after selling your previous main residence. You must sell the old property within 36 months (3 years) of buying the new one, and claim the refund within 12 months of selling (or 12 months from filing your SDLT return, whichever is later). The refund is the full 5% surcharge amount you paid. Your solicitor can handle the amendment, or you can do it yourself through HMRC. The refund typically takes 4-6 weeks to process.
