You can use this to calculate the amount of LTT you will need to pay for Welsh transactions completed on or after 1 April 2018.
The calculation is based on the rates and bands approved by the National Assembly for Wales.
You need to determine if higher rates apply to your transaction. If you are an individual and already own one or more residential properties you may need to pay the higher residential rate. If you are replacing your main residence higher rates may not apply.
This calculator is a tool to help you assess the tax you need to pay. It is your responsibility to make sure that the information in your return is accurate.
Linked transactions, acquisitions involving multiple dwellings, persons exercising collective rights and acquisitions of relief may require different calculations.
