Buying a second home or a buy-to-let property comes with a bigger Stamp Duty bill than buying your only residence. This guide covers how second home Stamp Duty works across England, Northern Ireland, Scotland and Wales, what the current rates are, when you’re exempt, and how to work out what you’ll owe.
What Is Stamp Duty?
England and Northern Ireland
Stamp Duty Land Tax (SDLT) is payable when you buy a property or land above a certain value in England and Northern Ireland. It applies to most purchases, including:
- Freehold property
- Leasehold property, whether a new or existing lease
- Property bought through a shared ownership scheme
- Land
If the property will be your main and only residence, you pay Stamp Duty at the standard rates. If you’re buying a second home or a buy-to-let property, you pay the standard rates plus a 5 percent surcharge on each band. The rates are identical for second homes and buy-to-let purchases, since both count as additional residential property.
Scotland
In Scotland, the equivalent tax is LBTT (Land and Buildings Transaction Tax), which works on a similar principle to Stamp Duty but with its own thresholds and rates.
On top of standard LBTT, second homes and buy-to-lets in Scotland attract ADS (Additional Dwelling Supplement), a flat 8 percent of the full purchase price.
Wales
In Wales, the tax is LTT (Land Transaction Tax), again similar in principle but with separate thresholds and rates from Stamp Duty.
Second homes and buy-to-lets in Wales are charged at the higher rates of LTT, which sit entirely apart from the main residential rates and bands.
How Stamp Duty Is Calculated
Stamp Duty is worked out in bands, with each band taxed at its own rate rather than the whole purchase price being taxed at one rate.
Example – main residence purchase at £300,000:
- 0% on the first £125,000
- 2% on the next £125,000
- 5% on the remaining £50,000
- Total Stamp Duty payable: £5,000
Second Home Stamp Duty Bands
The same banded structure applies to second homes and buy-to-lets, but with a 5 percent surcharge added to each band.
Example – second home or buy-to-let purchase at £300,000:
- 5% on the first £125,000
- 7% on the next £125,000
- 10% on the remaining £50,000
- Total Stamp Duty payable: £20,000
Second Home Stamp Duty Rates (England and Northern Ireland)
| Property Value | Standard SDLT Rate (from 1/4/25) | SDLT Rate on Second Homes or Buy-to-Lets (from 1/4/25) |
|---|---|---|
| Up to £125,000 | 0% | 5% |
| £125,001 – £250,000 | 2% | 7% |
| £250,001 – £925,000 | 5% | 10% |
| £925,001 – £1,500,000 | 10% | 15% |
| From £1,500,001 | 12% | 17% |
Worked Example: £700,000 Second Home
- 5% on the first £125,000 = £6,250
- 7% on the next £125,000 (£125,001 – £250,000) = £8,750
- 10% on the remaining £450,000 (£250,001 – £700,000, within the £250,001 – £925,000 band) = £45,000
- Total second property Stamp Duty: £60,000
Second Home LBTT and ADS Rates in Scotland
| Property Value | Standard Residential LBTT Rate |
|---|---|
| Up to £145,000 | 0% |
| £145,001 – £250,000 | 2% |
| £250,001 – £325,000 | 5% |
| £325,001 – £750,000 | 10% |
| Over £750,000 | 12% |
ADS is charged at 8 percent of the total purchase price, on top of the LBTT above.
Worked Example: £300,000 Second Home in Scotland
- 0% on the first £145,000 = £0
- 2% on the next £105,000 = £2,100
- 5% on the next £50,000 = £2,500
- Plus 8% ADS on £300,000 = £24,000
- Total (LBTT + ADS): £28,600
Second Home Main and Higher Rate LTT in Wales
| Property Value | Main Residential LTT Rate | Property Value | Higher Rate LTT |
|---|---|---|---|
| Up to £225,000 | 0% | Up to £180,000 | 5% |
| £225,001 – £400,000 | 6% | £180,001 – £225,000 | 8.5% |
| £400,001 – £750,000 | 7.5% | £225,001 – £400,000 | 10% |
| £750,001 – £1,500,000 | 10% | £400,001 – £750,000 | 12.5% |
| Over £1,500,000 | 12% | £750,001 – £1,500,000 | 15% |
| Over £1,500,000 | 17% |
Worked Example: £300,000 Second Home in Wales
- Higher Rate LTT at 5% on the first £180,000 = £9,000
- Higher Rate LTT at 8.5% on the next £70,000 = £5,950
- Higher Rate LTT at 10% on the next £50,000 = £5,000
- Total Higher Rate LTT payable: £19,950
Non-UK Residents
Non-UK residents pay a further 2 percent surcharge on top of the standard rates, applying to any property or land purchase over £40,000.
This applies even if only one buyer on the purchase is an overseas resident. In practice, this means a non-UK resident buying a second home faces 7 percent above the standard rate in total, while one buying their only residence faces 2 percent above the standard rate.
What Counts as a Second Home or Buy-to-Let?
If you already own a home, any further residential property you buy for personal use counts as a second home, and the 5 percent surcharge applies. The same goes for any additional property bought with the intention of letting it out.
This holds true even if:
- Your existing property is a holiday home abroad and this is your first UK purchase
- Your other property is held under shared ownership
- Your other property is freehold or leasehold
As long as you own a home, any new residential property purchase is treated as an additional property. It makes no difference whether you bought, inherited, or were added to the title deeds of your existing property – it still counts as ownership.
Why Is Stamp Duty Higher on Second Homes?
The surcharge exists to manage demand in the housing market and give priority to people buying a home to live in. Second homes and buy-to-let purchases can reduce the supply of property available to local buyers and put upward pressure on prices, so the surcharge is intended to discourage investors from competing directly with home movers and first-time buyers. It also raises additional revenue and encourages a more balanced spread of property ownership.
When Do You Have to Pay?
Stamp Duty must be paid within 14 days of completing the purchase. Missing this deadline results in a penalty, with interest accruing on the amount owed.
How Do You Pay?
If a solicitor, conveyancer, or agent is handling your purchase, they’ll usually submit the Stamp Duty return as part of completion and add the amount to their fees, so you pay it through them.
If this isn’t offered, you can file the return yourself and pay HMRC directly, following their process.
Can You Avoid Second Home Stamp Duty?
Outside of specific exemptions (such as the first-time buyer exemption), there’s no way to avoid the surcharge if anyone on the title deeds already owns another property.
One option to reduce exposure is a joint borrower, sole proprietor arrangement, where both people are named on the mortgage but only one, typically a first-time buyer, is on the title deeds.
If you’re married or in a civil partnership, you’re treated as a single unit for Stamp Duty purposes – if either of you owns another property, the surcharge applies regardless of whose name is on the title deeds.
When Are You Exempt?
You’re exempt from the second home surcharge if:
- The property, or your share of it, is valued under £40,000
- You’re buying a caravan, mobile home, or houseboat
Even outside these exemptions, it’s sometimes possible to claim back the surcharge you’ve paid.
Do First-Time Buyers Pay the Surcharge on a Buy-to-Let?
Technically, a first-time buyer can’t purchase a second home, since they don’t yet own a first. Lenders can be harder to find for a first-time buyer wanting a buy-to-let mortgage, but it isn’t impossible. If a first-time buyer does purchase a buy-to-let, they pay Stamp Duty at the basic rate only, with no surcharge applied.
Buying a New Main Residence While Keeping Your Existing Property
If you already own a property you intend to keep and you buy another, you’ll pay the second home surcharge on the new purchase, whether it becomes your main residence or not, since you technically own more than one property at that point.
If you go on to sell your original home, you may be able to claim back the surcharge you paid on the new purchase.
Claiming Back the Second Home Surcharge
You can claim back the surcharge if the new property becomes your main residence and you sell your previous home within 3 years of the new purchase.
In practice, this covers situations where someone buys a new main residence before selling their previous one, initially paying the standard rate plus the 5 percent surcharge. If the previous property is then sold within 3 years, a refund of the surcharge can be claimed. This is particularly useful if a previous sale falls through or takes longer than expected, or where a quick relocation is needed.
Other Taxes on Second Properties
Stamp Duty is only paid once, at the point of purchase. Beyond that, you’ll pay Council Tax for as long as you own the property.
Any further tax depends on how the property is used and whether you later sell it:
- Letting the property out as a buy-to-let may mean paying Income Tax on the rental income
- Selling the property may trigger a Capital Gains Tax liability
