Second Home Stamp Duty Calculator 2025 - 26: Surcharge Rates and Calculator
Use this second home stamp duty calculator for holiday homes, pied-à-terres, weekend residences and other personal-use additional properties. The page is intentionally separate from the buy-to-let version: the tax mechanics are often similar, but the user's decision context is different. A second-home buyer is normally assessing personal affordability, refund eligibility and exemptions, not rental yield.
In short
On a second home, you usually pay standard residential stamp duty plus the additional-property charge. In England & Northern Ireland this currently adds 5 percentage points to the SDLT bands. Scotland applies an 8% ADS, while Wales uses separate higher residential LTT rates. Refunds may be available if you replace your main residence within 36 months.
Second home stamp duty calculator: personal-use additional property
The calculator should open in Additional Dwelling mode, with England & NI selected and £300,000 entered as the default price. The copy should speak to personal second-home buyers, not landlords: holiday homes, city crash pads, homes for family members and non-investment second residences. Keep the buy-to-let page linked but distinct.
Intent distinction: BTL page = investor; second home page = personal-use additional property.
What counts as an additional dwelling for SDLT purposes?
An additional dwelling is broadly a residential property bought when the buyer will own another residential property worth £40,000 or more at completion and is not replacing their only or main residence. The rules can apply even if the other property is overseas, jointly owned, inherited or not rented out. The practical question is not 'will I use this as a second home?' but 'will I own more than one dwelling at completion?'
This section should answer 'what counts as a second home for stamp duty?' in the first 100 words.
Second home surcharge rates by jurisdiction
Second home tax rules vary across the UK. England and Northern Ireland use SDLT higher rates, Scotland uses LBTT plus ADS, and Wales uses LTT higher residential rates. The calculator should avoid the misleading phrase 'UK second home stamp duty' unless it immediately explains the jurisdiction split.
| Jurisdiction | Tax | Current second-home treatment | Display in calculator |
|---|---|---|---|
| England & Northern Ireland | SDLT | 5 percentage points above standard SDLT rates | Show standard SDLT, surcharge and total. |
| Scotland | LBTT + ADS | 8% ADS on full price plus standard LBTT | Show standard LBTT, ADS and total. |
| Wales | LTT | Higher residential LTT rates by band | Show standard LTT comparison and higher-rate total. |
The legacy +4% Wales shorthand is not suitable for current WRA higher residential rates.
Worked example: £300,000 second home in England
A £300,000 second home in England & NI currently produces total SDLT of £20,000. The standard SDLT is £5,000 and the additional-property charge adds £15,000.
| Component | Calculation | Tax due |
|---|---|---|
| Standard SDLT | 0% on £125,000 + 2% on £125,000 + 5% on £50,000 | £5,000 |
| Additional-property charge | 5% of £300,000 | £15,000 |
| Total SDLT | Standard SDLT + additional-property charge | £20,000 |
If old copy says the surcharge is £9,000 at £300,000, that reflects the former 3% rate and should be updated before publication.
Worked example: £450,000 second home in Wales
A £450,000 Welsh second home should use current higher residential LTT bands, not a flat add-on. The current higher-rate LTT is £36,200. The main residential LTT comparison is £14,250, so the higher-rate impact is £21,950.
| Component | Calculation | Tax due |
|---|---|---|
| Main residential LTT comparison | 0% to £225,000; 6% to £400,000; 7.5% to £450,000 | £14,250 |
| Higher residential LTT | 5% to £180,000; 8.5% to £250,000; 10% to £400,000; 12.5% to £450,000 | £36,200 |
| Higher-rate impact | Higher residential LTT minus standard LTT | £21,950 |
Use 'higher-rate impact' rather than 'surcharge' for Wales because the rate structure is banded.
Second home stamp duty refund: selling your main home within 3 years
The most common refund scenario is an overlap in main-residence ownership. If you buy a new main home before selling your previous main home, you may pay the higher rates at completion. If you then sell the previous main home within 36 months, you can normally apply for a refund of the additional-property element. The refund calculator input should be simple: original purchase price + surcharge rate or higher-rate impact paid.
| Refund input | Formula | Example |
|---|---|---|
| England & NI surcharge refund | Purchase price × 5% | £300,000 × 5% = £15,000 |
| Scotland ADS refund | Purchase price × 8% | £400,000 × 8% = £32,000 |
| Wales refund estimate | Higher-rate LTT paid minus standard LTT | £450,000 example: £21,950 |
Refunds are time-sensitive; users should verify deadlines and forms with the relevant authority.
Exceptions to the second home surcharge
The page should list exceptions clearly because this is a high-intent FAQ cluster. The surcharge generally should not apply where the buyer is replacing a main residence and the previous main home has already been sold before completion. Court-ordered divorce transfers can also be exempt. Properties under £40,000, caravans, mobile homes and houseboats are outside the normal higher-rate dwelling rules. Small recently inherited shares, including shares of 50% or less, can be disregarded in specific circumstances.
| Exception | Plain-English treatment | Content warning |
|---|---|---|
| Replacing main residence | No surcharge if previous main home already sold before completion | If sold after completion, refund route may apply. |
| Court-ordered transfers | Often exempt in divorce or separation contexts | Link to transfer-of-equity page. |
| Inherited share ≤50% | May be ignored for higher-rate tests in defined circumstances | Do not oversimplify; facts matter. |
| Property under £40,000 | Generally outside higher-rate rules | Confirm full consideration. |
| Caravan, mobile home, houseboat | Generally not treated as SDLT dwellings | Different legal categories may still apply. |

Holiday let, second home and overseas property rules
A holiday let and a personal second home can produce the same higher-rate stamp duty outcome even when income tax treatment differs later. Overseas property also matters: a buyer with a home in Spain, Dubai or Australia who buys a second UK dwelling can be treated as already owning another residential property. The calculator should include a soft prompt: 'Do you own any residential property anywhere in the world?'
This page should not imply that personal use avoids the surcharge. It usually does not.
Check the total second-home stamp duty bill and whether a main-residence refund route may apply.

You pay £15,000 extra SDLT on a £300,000 second home in England & NI under the current 5% additional-property surcharge. The total SDLT is £20,000, made up of £5,000 standard SDLT plus £15,000 surcharge.
You currently pay £36,200 LTT on a £450,000 second home in Wales under higher residential rates. The standard LTT would be £14,250, so the higher-rate impact is £21,950.
A second home is usually a residential property bought when you already own another dwelling and are not replacing your main residence. The rule can apply to holiday homes, pied-à-terres, homes for family use and other additional residences.
Yes, an overseas residential property can count when assessing whether a UK purchase is an additional dwelling. The SDLT test looks at residential property ownership anywhere in the world, not only homes in the UK.
You can usually claim a refund if you paid the additional-property surcharge because you had not sold your old main home, then sell that previous main residence within 36 months. The refund is based on the surcharge element, not the standard stamp duty.
No, you usually do not pay the additional-property surcharge if the new property replaces your main residence and your previous main residence has already been sold before completion. The key test is your property ownership position at completion.
Yes, purchases under £40,000 are generally outside the higher-rate additional-dwelling rules. This low-value exclusion is narrow and should not be assumed for normal residential purchases.
No, caravans, mobile homes and houseboats are generally not treated as dwellings for SDLT higher-rate purposes. The surcharge is aimed at purchases of residential land and buildings.
A small recently inherited property share may be ignored for higher-rate SDLT purposes, including where the inherited share is no more than 50% within the relevant period. Buyers should confirm the facts because inherited ownership can still affect tax treatment.
The additional-dwelling stamp duty logic is usually the same for a holiday let and a second home. A furnished holiday let may have different income tax or business-rate issues, but the acquisition surcharge can still apply.
