Why Second Homes Cost More in Stamp Duty
If you already own a property and are buying another one, you will normally pay higher residential rates on top of the standard property tax rules. That can apply whether the new property is a holiday home, a buy-to-let, or a home for a family member.
Each UK nation runs this differently. England and Northern Ireland use higher SDLT bands, Scotland charges the Additional Dwelling Supplement through LBTT, and Wales uses separate higher-rate LTT bands.
How the Second Home Surcharge Is Calculated
The calculator uses the same underlying rate engine as the England, Scotland, and Wales calculators. For England & Northern Ireland, the worked example above updates directly from the selected regional rate config when you switch region.
Standard stamp duty is tiered, which means each rate applies only to the slice of the price in that band. Additional-property rates are also applied through bands in the calculator, so the safest approach is to calculate the full purchase price rather than relying on a single headline percentage.
Can You Get the Surcharge Back?
If you buy a new main home before selling your previous one, you may need to pay the additional-property amount upfront. You may then be able to reclaim it if you sell the old main residence within the relevant deadline. See our stamp duty refund guide for the detailed process.
Second Home vs Buy-to-Let Stamp Duty
Second home stamp duty and buy-to-let stamp duty are usually the same thing for tax purposes. The rules focus on whether you own another residential property, not whether you intend to live in the new property, rent it out, or use it as a holiday home.

FAQ Section: Questions You Might Have
How is stamp duty calculated on a second home?
Standard stamp duty is calculated first using the normal tiered bands for your region, then the second-home surcharge or higher-rate structure is applied. The two figures are added together for your total bill.
How much is stamp duty on a second home?
It depends on the purchase price, the region, and the current higher-rate rules. Enter your price and choose England and Northern Ireland, Scotland, or Wales in the calculator to get an exact figure.
How do you calculate stamp duty on a second home?
Work out the standard property tax due on the purchase price using your region's bands, then apply the additional-property rates. England and Scotland effectively add a percentage surcharge, while Wales uses separate higher residential bands.
Do first-time buyers pay the second home surcharge?
No. The surcharge only applies if you already own another residential property. First-time buyers by definition do not own another home, so they pay standard rates and may qualify for first-time buyer relief where available.
Can you add the second home surcharge to your mortgage?
No. Stamp duty, LBTT, or LTT is a purchase cost and is normally paid in cash through your solicitor or conveyancer. Lenders do not treat it as part of the property's value.
Will the second home surcharge change in 2026?
No further changes have been announced for 2026 at the time of writing. This calculator uses the current rates in the site's stamp duty engine and will be updated if official rates change.
Do you pay the surcharge on a property bought through a limited company?
Yes. Company purchases of residential property usually attract the higher rates, and a company generally cannot claim main residence replacement treatment in the same way as an individual buyer.
What counts as owning another property for the surcharge?
A property can count if you own another residential property anywhere in the world when the purchase completes. Rules for spouses, civil partners, inherited shares, and replacement main residences can be complex, so check with your solicitor.
Is the second home surcharge the same as buy-to-let stamp duty?
Yes. There is no separate buy-to-let stamp duty rate. The higher rates apply to additional residential properties whether you plan to live in them occasionally, let them out, or keep them as holiday homes.
How is stamp duty calculated for a second home if I am also a non-UK resident?
In England and Northern Ireland, the non-UK resident surcharge can apply on top of the additional-property rates. Scotland and Wales have separate property tax systems, so get advice if residency is part of your transaction.
