Stamp Duty Tax Calculator

Understanding the costs involved in purchasing a property is an essential step in your home-buying journey. One of these costs is Stamp Duty Land Tax (SDLT). Use our simple Stamp Duty Calculator to get an estimate of the tax you’ll need to pay on your property purchase. 

What Is Stamp Duty Tax?

Stamp Duty Land Tax is a government tax paid by buyers when purchasing property or land above a certain price threshold. It applies to both residential and commercial properties. The amount payable varies depending on the property’s value and the type of buyer you are.

What's The Benefits for Different Buyer Types?

Standard buyers moving homes can benefit from zero Stamp Duty on the first £125,000 of their property purchase. Buyers purchasing additional properties, such as buy-to-let investments or second homes, are subject to an extra 5% surcharge on top of the standard Stamp Duty rates.

First-time buyers can claim tax relief on properties valued up to £300,000, and pay tax on the amount over this threshold. This is how tax is calculated for first-time buyers:
 

  • Up to £300,000 = 0%
     

  • The next £675,000 ( the portion from £250,001 to £925,000) = 5%
     

  • The next £575,000 (the portion from £925,001 to £1.25 million) = 10%
     

  • The final amount (the portion above £1.25 million) = 12%


​

Why Is Stamp Duty Tax Needed?

Stamp Duty contributes to public services, infrastructure development, and government spending. It is a key source of revenue that supports community improvements and public projects.
