Stamp Duty on a Second Home or Buy-to-Let Property
Second homes and buy-to-let properties attract a 3% stamp duty surcharge on top of standard rates. Here is the exact calculation, the exceptions, and what changed in 2024.
Buying a second property in England means paying substantially more stamp duty than a first-time buyer. The surcharge significantly affects the economics of buy-to-let investment and holiday homes.
Standard Rates vs Second Home Rates (England)
Standard Stamp Duty Land Tax (SDLT) rates (from Oct 2024):
Up to £125,000: 0%
£125,001 to £250,000: 2%
£250,001 to £925,000: 5%
£925,001 to £1,500,000: 10%
Above £1,500,000: 12%
Second home / additional dwelling surcharge: +3% on ALL bands
Effective additional dwelling rates:
Up to £250,000: 3% (was 0% or 2%)
£250,001 to £925,000: 8%
£925,001 to £1,500,000: 13%
Above £1,500,000: 15%
Worked Example: Buy-to-Let at £280,000
Standard SDLT:
Up to £125,000: 0% x £125,000 = £0
£125,001-£250,000: 2% x £125,000 = £2,500
£250,001-£280,000: 5% x £30,000 = £1,500
Standard total: £4,000
Second home surcharge (3% of total purchase price):
£280,000 x 3% = £8,400
Total SDLT payable: £4,000 + £8,400 = £12,400
As a percentage: £12,400 / £280,000 = 4.43%
vs standard rate: £4,000 / £280,000 = 1.43%
The surcharge nearly triples the stamp duty bill at this price point.
When the Surcharge Applies (and When It Doesn't)
APPLIES when:
- Buying a residential property and you already own one or more residential properties
- The property is not replacing your main residence
- Buying as a company (always pays the surcharge)
DOES NOT APPLY when:
- The property costs less than £40,000 (below minimum threshold)
- You are replacing your main residence (main home sold, buying another)
- Property is a caravan, mobile home, or houseboat
- Property is commercial (SDLT still applies but different rates)
Replacing main home rule:
If you buy a new main home BEFORE selling the old one,
you pay the surcharge initially.
If you sell within 3 years: HMRC refunds the surcharge.
Refund must be claimed within 12 months of the sale.
Impact on Buy-to-Let Returns
Buy-to-let at £280,000, rental yield 5%:
Annual gross rent: £280,000 x 5% = £14,000
Standard SDLT: £4,000 -- recovered in 3.4 months rent
Second home SDLT: £12,400 -- recovered in 10.6 months rent
This is why gross yield requirements for buy-to-let have risen:
The upfront cost is now much higher, requiring longer to recover
the additional stamp duty before the investment is profitable.
At 5% yield with mortgage: most investors now need 6-7% gross yield
to achieve acceptable returns after SDLT, mortgage, maintenance, and voids.
