> This guide covers the Stamp Duty Land Tax (SDLT) additional property surcharge, which applies an extra 5% tax to purchases of second homes or buy-to-let investments in England and Northern Ireland from 1 April 2025. Learn about the latest rates, math calculations, and key refund rules.

The SDLT additional property surcharge is a 5% levy applied to residential property purchases when the buyer already owns another dwelling. It works by stacking an extra 5% on top of all standard tax bands rather than acting as a separate self-contained transaction tax. If you buy a second home or buy-to-let property in England or Northern Ireland, this higher rate will apply unless a specific exemption is met.

## Key Takeaways: Second Home Stamp Duty

- **5% Surcharge Rate**: This additional tax rate is stacked directly on top of the standard residential SDLT bands.
- **Effective Date**: This 5% rate applies to transactions completed on or after 1 April 2025, as updated by section 51 of the Finance Act 2025.
- **Global Reach**: The surcharge applies if you own or part-own another residential property anywhere in the world on the day of completion.
- **Exemption Potential**: You can avoid the surcharge entirely if you sell your old main residence on or before the same day you complete on your new one.
- **Refund Opportunity**: If you buy your new home before selling your old one, you can claim a refund of the 5% surcharge if you sell the old home within 36 months.

## How does the 5% additional property surcharge work?

The 5% additional property surcharge is a tax stacked on top of standard residential SDLT bands, rather than a separate self-contained tax.

According to the legislation set out in Schedule 4ZA to the Finance Act 2003, the surcharge does not replace standard SDLT rates. Instead, the higher rate is applied automatically directly above the active standard residential rate for each specific price band. For instance, any price band that otherwise carries a 0% standard SDLT rate incurs a 5% surcharge rate, while a band with a 2% standard rate carries a 7% surcharge rate.

## What are the second home Stamp Duty rates for 2026?

The following rates show the combined stamp duty charges on additional properties in England and Northern Ireland effective from 1 April 2025.

| Purchase price band | Standard rate | +5% surcharge | Second home rate |
| --- | --- | --- | --- |
| Up to £125,000 | 0% | +5% | 5% |
| £125,001 – £250,000 | 2% | +5% | 7% |
| £250,001 – £925,000 | 5% | +5% | 10% |
| £925,001 – £1,500,000 | 10% | +5% | 15% |
| Over £1,500,000 | 12% | +5% | 17% |

## How is the second home surcharge calculated?

The second home surcharge is calculated using a progressive, band-by-band method rather than a flat percentage of the overall purchase price.

To illustrate this progressive calculation, consider the purchase of a second home valued at £300,000. Under the rates effective from 1 April 2025, the tax liability is divided across three separate rate bands:

- **First Band**: The first £125,000 is taxed at the 5% rate, which equals £6,250.
- **Second Band**: The portion between £125,001 and £250,000 (£125,000) is taxed at the 7% rate, which equals £8,750.
- **Third Band**: The remaining £50,000 between £250,001 and £300,000 is taxed at the 10% rate, which equals £5,000.

Adding these amounts together results in a total SDLT liability of £20,000. Under standard residential rates, a buyer purchasing a main residence with no other property would pay only £5,000 on a £300,000 property, meaning the 5% surcharge adds an extra £15,000 of tax liability.

## When does the 3% or 5% higher rate apply?

The higher rate of SDLT applies whenever a buyer purchases a residential property while already holding an interest in another home.

- **Global Ownership**: You own or part-own any other residential property anywhere in the world on the day your transaction completes.
- **Minimum Value**: The purchase price of the additional residential property being bought exceeds £40,000.
- **Investment Use**: The property is being purchased specifically to be used as a holiday home, secondary residence, or buy-to-let investment.

## When do you not have to pay the second home surcharge?

The 5% additional property surcharge does not apply if you meet specific standard exemptions established by HM Revenue and Customs.

If you sell your old main residence on or before the same day you complete the purchase of your new main residence, you do not pay the surcharge. Additionally, purchases under £40,000 do not incur the surcharge, though they are still counted as owned dwellings for future transactions. Non-stationary structures, such as caravans, mobile homes, and houseboats, are also completely exempt from the additional property surcharge.

## How does the 36-month SDLT refund rule work?

The 36-month refund rule allows buyers to reclaim the 5% surcharge if they sell their old main home after completing their new purchase.

If you buy your new main residence before selling your old one, you must pay the 5% surcharge upfront at completion. You can claim a full refund of this surcharge from HM Revenue and Customs if you sell your old main residence within 36 months of the completion date on your new home. Buyers should note the cash-flow impact of this rule, as they must secure the extra funds to pay the tax upfront before waiting to recover them.

## How much stamp duty do non-UK residents pay?

Non-UK residents must pay an extra 2% surcharge on top of standard and second-home stamp duty rates when purchasing property.

If you are not physically present in the UK for at least 183 days during the 12 months immediately preceding completion, you are classified as a non-resident. This triggers an additional 2% non-resident surcharge that stacks directly on top of the standard and second-home rates. Consequently, a non-resident purchasing a second home faces a total surcharge of 7% above the standard residential rates across all bands.

## What is the deadline for paying SDLT to HMRC?

The strict legal deadline to file your SDLT return and pay any tax due to HM Revenue and Customs is 14 days post-completion.

It is essential to submission requirements that both filing and payment are finalized within this calendar window. Your professional conveyancer or legal representative typically manages this paperwork and submits the payment on your behalf. Failing to meet this 14-day timeline can result in automatic financial penalties and interest charges accruing on the unpaid tax.

### What is the stamp duty on a second home UK?

In England and Northern Ireland, buying a second home triggers a 5% surcharge on top of standard SDLT rates. For example, a second home under £125,000 has a 5% rate, and the rate rises across bands up to 17% for portions above £1.5 million.

### Can I claim back the second home stamp duty surcharge?

Yes, you can claim a refund from HMRC if you bought your new main residence before selling your old main residence. To qualify, you must sell your previous main residence within 36 months of purchasing your new home.

### Does the 5% surcharge apply if the property is under my partner's name?

Yes, married couples and civil partners are treated as a single unit by HMRC. If either partner owns another residential property globally, the 5% surcharge will apply to a new transaction in either partner's name.

### Do you pay second home stamp duty on global properties?

You do not pay UK SDLT on properties located overseas. However, owning a property anywhere in the world on the day you complete a UK transaction will trigger the 5% surcharge on your UK purchase.

### How long do I have to claim back SDLT after selling my old home?

You must request your SDLT refund from HMRC within 12 months of the date you sold your previous main residence, or within 12 months of the filing date of your SDLT return, whichever is later.
