Stamp Duty Land Tax SDLT Calculator for Property Buyers

Understanding the Stamp Duty Land Tax (SDLT) in the UK

Stamp Duty Land Tax (SDLT) is a tax you must pay when purchasing a residential property in England or Wales. This SDLT calculator helps you get a clear estimate of the amount you'll need to pay before you buy, making it easier to plan your finances accurately. Whether you're a first-time buyer or investing in an additional property, our tool simplifies the calculation process.

Who Pays Stamp Duty?

If you're buying property over £250,000 in England or Wales, you'll usually need to pay SDLT. However, first-time buyers can enjoy relief on properties valued up to £425,000, and partial relief up to £625,000. This tool reflects the latest thresholds and reliefs.

Rates Based on Buyer Type

• First-Time Buyers: Pay no stamp duty on the first £425,000, and 5% on the portion between £425,001 and £625,000.
• Home Movers: Pay no SDLT up to £250,000, then progressive rates above this threshold.
