How is Stamp Duty Land Tax (SDLT) calculated?
Stamp Duty Land Tax (SDLT) is a tax payable when purchasing property or land in England and Northern Ireland. As of 1 April 2025, several key changes have been implemented, affecting both first-time buyers and those purchasing additional properties. It’s crucial to understand these rates to accurately calculate your tax liability.
Residential property rates (effective from 1 April 2025)
- Up to £125,000: 0%
- £125,001 – £250,000: 2%
- £250,001 – £925,000: 5%
- £925,001 – £1.5 million: 10%
- Above £1.5 million: 12%
These rates apply to the portion of the property price within each band.
First-time buyer relief
First-time buyers benefit from reduced rates:
- Up to £300,000: 0%
- £300,001 – £500,000: 5% (on the amount above £300,000)
IMPORTANT: If the purchase price exceeds £500,000, standard residential rates apply to the entire amount.
HIGHER RATES FOR ADDITIONAL PROPERTIES
If purchasing an additional residential property (e.g., buy-to-let or second home), a 3% surcharge applies on top of the standard rates:
- Up to £125,000: 3%
- £125,001 – £250,000: 5%
- £250,001 – £925,000: 8%
- £925,001 – £1.5 million: 13%
- Above £1.5 million: 15%
This surcharge applies if you own another property anywhere in the world.
NON-UK RESIDENT SURCHARGE
Non-UK residents are subject to an additional 2% surcharge on residential property purchases. This is in addition to the standard rates and any applicable surcharges for additional properties.
NON-RESIDENTIAL AND MIXED-USE PROPERTIES
For non-residential or mixed-use properties:
- Up to £150,000: 0%
- £150,001 – £250,000: 2%
- Above £250,000: 5%
Note: Mixed-use properties combine residential and non-residential elements, such as a shop with a flat above.
CALCULATING AND PAYING SDLT
- SDLT must be paid within 14 days of completion.
- Your solicitor will typically handle the calculation and submission of the SDLT return to HM Revenue & Customs (HMRC).
- Delays in payment can result in penalties and interest charges.
