Overview

The Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017 (the Act) applies a tax on land transactions that take place in Wales. This is called the “land transaction tax” and affects people who purchase a residential property to live in, as well as persons who acquire a non-residential property (as part of a business, for example). 

Provision is made about the key concepts underlying the tax, including:

  • which transactions count as land transactions;
  • what is a chargeable interest and when it applies;
  • which land transactions the tax is charged upon;
  • tax bands and rates;
  • how to calculate the tax;
  • the reliefs available from the tax.

The Act explains how the tax applies to leases, and to companies, partnerships and trusts. It also explains when and by whom returns and payments are required to be made to the Welsh Revenue Authority. Provision is also made in order to counteract avoidance arrangements in relation to devolved taxes. 

Further information on the Act can be found in the Explanatory Notes:
