This guide is fully updated for the 2026/27 HMRC tax year. All calculations and tax rules have been audited against official UK legislation.
For property investors, landlords, and anyone buying an additional property, Stamp Duty represents a major upfront cost. In England and Northern Ireland, additional residential properties are subject to a significant surcharge known as the Higher Rates for Additional Dwellings (HRAD). This surcharge was increased to **5%** in the Autumn Budget, representing a massive tax increase for buy-to-let purchases and holiday homes. In this guide, we break down the surcharge rates, rules, and exemptions for the 2026/27 tax year.
What is the Additional Property Surcharge?
The surcharge is an extra **5% tax** added on top of the standard residential Stamp Duty Land Tax (SDLT) bands. It applies to any residential purchase where, at the end of the transaction day, the buyer owns **two or more residential properties** globally and is not replacing their main home.
Second Home & BTL Stamp Duty Bands (2026/27)
The table below details the standard residential rates compared to the BTL/Second Home rates (including the 5% surcharge) for the 2026/27 tax year:
| Property Value Band | Standard Residential SDLT Rate | Second Home / BTL SDLT Rate (5% Surcharge) |
|---|---|---|
| £0 to £125,000 | 0% | 5% |
| £125,001 to £250,000 | 2% | 7% |
| £250,001 to £925,000 | 5% | 10% |
| £925,001 to £1,500,000 | 10% | 15% |
| Over £1,500,000 | 12% | 17% |
How the Surcharge is Triggered
The 5% surcharge is legally triggered if the transaction meets the following criteria:
- The purchase price is **£40,000 or more**.
- The property is residential (non-residential or commercial properties are completely exempt from this surcharge).
- You own another residential property anywhere in the world (including outside the UK) with a market value of £40,000 or more.
- You are not replacing your primary residence.

Replacing Your Main Residence: The 36-Month Refund Rule
If you buy a new home to live in before you have sold your old home, you must pay the 5% surcharge on the purchase day because you temporarily own two properties. However, if you sell your previous main home within **36 months (3 years)** of the purchase date, you can claim a **100% refund** of the 5% surcharge from HMRC. You must claim this refund within 12 months of selling your old home or within 12 months of the filing date of the SDLT return, whichever is later.
What People Search For: FAQs on Second Home & Buy-to-Let Stamp Duty
1. How much is stamp duty on a second home or buy-to-let in 2026/27?
The stamp duty rate starts at 5% for properties under £125,000, 7% on the portion between £125,001 and £250,000, 10% on the portion between £250,001 and £925,000, 15% on the portion between £925,001 and £1.5 million, and 17% on any amount over £1.5 million. This reflects the standard rates plus the 5% HRAD surcharge.
2. What is the 36-month refund rule for replacing a main residence?
If you buy a new main home before selling your old one, you must pay the 5% surcharge. If you sell your previous main home within 36 months of the new purchase, you can apply to HMRC for a full refund of the 5% surcharge paid.
3. Do limited companies pay the 5% surcharge on all property purchases?
Yes. Limited companies must pay the 5% surcharge on all residential property purchases from the very first pound. There is no tax-free allowance or lower band starting rate for corporate buyers of residential real estate.
4. Does the second home stamp duty surcharge apply if I own property abroad?
Yes, absolutely. HMRC counts residential properties owned anywhere in the world. If you own a house or flat overseas and are buying a residential property in the UK (and not replacing a main residence), you will be charged the 5% surcharge.
5. What counts as a second home for stamp duty purposes?
Any additional residential property you purchase for £40,000 or more is considered a second home if you already own a residential property. This includes buy-to-let investments, holiday homes, or properties you buy for family members.
6. Can a married couple own one home each to avoid the 5% surcharge?
No. HMRC treats married couples and civil partners as a single unit for Stamp Duty purposes. If one spouse owns a property, any additional property purchased by either spouse will automatically attract the 5% surcharge unless they are replacing their main residence.
7. Is there a way to legally avoid the stamp duty surcharge on second homes?
Legitimate options include purchasing a property that has a commercial element (mixed-use), buying 6 or more residential properties in a single transaction (which qualifies for commercial rates), or replacing your main residence within the 36-month window to claim a refund.
8. Do I pay the 5% surcharge on inherited properties or inheritances?
If you inherit a property or a share of one, you do not pay Stamp Duty on the inheritance itself. However, owning that inherited property will count as owning a home, meaning any future residential property you purchase will attract the 5% surcharge.
9. Does the 5% surcharge apply to residential properties purchased to be let out on Airbnb?
Yes. Furnished Holiday Lets (FHL) and Airbnb properties are treated as residential dwellings under UK tax law. Therefore, if you already own a main home, purchasing another property to use for short-term holiday letting will attract the 5% additional property surcharge.
10. What happens if I buy a second property for my children to live in?
If you buy the property in your own name (or jointly with your child) and you already own a residential property, the 5% surcharge will apply. To avoid the surcharge, you could consider gifting the deposit to your child so they can buy the property solely in their name, provided they are first-time buyers or do not own other properties.
