The UK Government has released a calculator that allows potential homeowners to calculate how much Stamp Duty they'll pay.

This calculator can be used for property purchases that are:

• for first-time buyers
• replacing main residence
• additional property
• residential or non-residential
• freehold or leasehold

The calculator will work out the SDLT payable for most transactions. You should check the guidance if you are uncertain about how SDLT applies to your purchase or if you believe it may qualify for a relief.

There are different rules for a corporate body purchasing residential property for more than £500,000.
