Purchasing a second home, holiday property, or buy-to-let investment in the UK comes with a significantly higher Stamp Duty Land Tax (SDLT) bill than buying a primary residence. Following two major changes in October 2024 and April 2025, many buyers are now paying substantially more SDLT than they expected. This comprehensive AccFirm guide explains the current rates, the 5% surcharge, how to calculate your SDLT liability, and the circumstances under which you may be entitled to a refund.
What Is Stamp Duty on a Second Home?
Stamp Duty Land Tax (SDLT) is a tax paid to HMRC when you purchase property or land in England and Northern Ireland above a certain value. For buyers who already own a residential property anywhere in the world, an additional surcharge applies on top of the standard SDLT rates. This is known as the Higher Rates for Additional Dwellings (HRAD) surcharge.
As of October 2024, this surcharge was increased from 3% to 5% , a significant uplift that substantially increases the SDLT bill for second home buyers and property investors. This change was announced in the Autumn Budget 2024 and took effect from 31 October 2024.
Current Stamp Duty Rates for Second Homes in England (from April 2025)
From 1 April 2025, the standard nil-rate SDLT threshold reverted from £250,000 back to £125,000. The second home rates, including the 5% surcharge, are as follows:
| Purchase Price Band | Standard SDLT Rate | Second Home Rate (incl. 5% surcharge) |
| 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% |
| Over £1,500,000 | 12% | 17% |
Note: SDLT is a tiered tax you pay the applicable rate only on the portion of the purchase price falling within each band, not on the entire purchase price. The 5% surcharge applies from the first pound on second home purchases where the property is worth more than £40,000.
Worked Examples: Second Home SDLT Calculations
Example 1: Buying a £300,000 Holiday Home
- 5% on the first £125,000 = £6,250
- 7% on the next £125,000 (£125,001–£250,000) = £8,750
- 10% on the final £50,000 (£250,001–£300,000) = £5,000
- Total SDLT: £20,000
- Compare to a first-time buyer paying £0 on the same property
- Compare to a home mover paying £5,000 on the same property
Example 2: Buying a £500,000 Buy-to-Let Property
- 5% on £0–£125,000 = £6,250
- 7% on £125,001–£250,000 = £8,750
- 10% on £250,001–£500,000 = £25,000
- Total SDLT: £40,000
- The additional 5% surcharge alone adds £25,000 to this bill versus standard residential rates
What Counts as an Additional Dwelling for SDLT Purposes?
The 5% surcharge applies whenever, at the end of the day of completion, you own two or more residential properties anywhere in the world. This includes:
- Any property you own outright or jointly with another person
- Properties you own but rent out (buy-to-let)
- Holiday homes, even if located overseas
- Inherited properties, even if you did not choose to purchase them
- Properties purchased jointly if any one buyer in the transaction already owns another property, the surcharge applies to the whole purchase
- Properties owned by a company you control
Who Is Exempt from the Second Home SDLT Surcharge?
The 5% surcharge does not apply in the following circumstances:
- The purchased property costs less than £40,000 — no surcharge applies below this threshold
- You are replacing your main residence: If you sell your main home on the same day as or before completing on a new purchase, you pay standard rates (not the surcharge)
- Charities and housing associations purchasing for qualifying purposes
- Certain property purchase arrangements involving annexes or granny flats valued at less than one-third of the total property price
- Properties with more than six units at completion treated as commercial property
Replacing Your Main Residence: The Three-Year Rule
One of the most commonly encountered exemptions is the main residence replacement rule. If you buy a new home before you sell your old one, you will technically own two properties at completion triggering the 5% surcharge. However, if you sell your previous main residence within three years of completing on the new purchase, you can apply to HMRC for a refund of the surcharge.
Key conditions for the refund:
- The property sold must have been your main residence
- You must sell within three years of the purchase completion date
- Apply to HMRC for the refund within 12 months of the sale date (or within 12 months of the SDLT filing deadline, whichever is later)
- Submit supporting documents: sale contracts, proof of ownership, completion statements
This refund can amount to tens of thousands of pounds always apply if eligible.
SDLT in Scotland and Wales: Different Rules Apply
Second home purchases in Scotland and Wales are subject to separate taxes with different rates:
Scotland Land and Buildings Transaction Tax (LBTT)
Scotland uses LBTT instead of SDLT. For additional residential properties in Scotland, a 6% surcharge applies (compared to 5% in England). Rates range from 8% on properties up to £145,000 to 20% on properties over £750,000.
Wales Land Transaction Tax (LTT)
Wales uses LTT. For second homes and buy-to-let properties in Wales, higher rates apply including a 5% rate on properties up to £180,000, rising to 16% on the portion above £1.5 million.
Companies Buying Residential Property
If a company purchases a single residential property worth more than £500,000, a flat 17% SDLT rate applies (as of April 2025), rather than the standard tiered rates. This is an anti-avoidance measure designed to prevent individuals from sheltering property portfolios within corporate structures to avoid higher SDLT rates. Companies with large property portfolios (Multiple Dwellings Relief was abolished in June 2024) now face a less favourable SDLT landscape than in previous years.
Non-UK Resident Surcharge
Non-UK residents face an additional 2% surcharge on residential property purchases in England and Northern Ireland, on top of both the standard rates and the 5% additional dwellings surcharge. An individual is treated as a non-UK resident for this purpose if they were not present in the UK for at least 183 days in the 12 months before the purchase. This can result in a combined surcharge of 7% for non-resident second home buyers.
SDLT Payment Deadline
SDLT must be paid and the SDLT land return filed with HMRC within 14 days of the completion date. Your solicitor or conveyancer normally handles this automatically as part of the conveyancing process. Missing the deadline results in penalties and interest charges from HMRC.
Frequently Asked Questions: Stamp Duty on Second Home
How much is the stamp duty surcharge on a second home in 2025?
From 31 October 2024, the additional dwellings surcharge is 5%, added on top of the standard SDLT rates. This applies to second homes, holiday homes, and buy-to-let properties in England and Northern Ireland.
Can I avoid the second home SDLT surcharge?
You can avoid the surcharge legitimately by selling your main residence before or on the same day as completing on the new purchase. If you pay the surcharge but sell your main home within three years, you can apply to HMRC for a refund.
Does inheriting a property trigger the second home surcharge?
Yes. An inherited property counts as an additional residential property for SDLT purposes. If you inherit a property and then buy another home, the 5% surcharge will apply unless you qualify for an exemption.
What if I buy with a partner who already owns property?
If any buyer in a joint purchase already owns a residential property, the 5% surcharge applies to the entire purchase. You cannot split ownership to avoid the surcharge HMRC treats all joint buyers as a single unit.
