You must pay Stamp Duty Land Tax (SDLT) if you buy a property or land over a certain price in England, Wales and Northern Ireland.
The current SDLT threshold is £125,000 for residential properties and £150,000 for non-residential land and properties.
Stamp duty rates have increased for anyone purchasing an additional property. From April 2016 a 3% surcharge has been applied on top of the normal SDLT rate. This means buy to let purchases now attract higher levels of SDLT unless individual ownership is limited to a single property.
