On 21 December 2020, the Welsh Government announced changes to the rates and bands of Land Transaction Tax. We’ve updated our LTT calculator to include the new rates that come into effect on 22 December 2020. The date you enter into the calculator decides which rates and bands it uses.

If higher residential rates apply to your transaction and you exchanged contracts before 21 December, but are completing on or after 22 December, the previous higher rates apply in most cases. The calculator will not take this into account. Further information is in our higher rates quick guide.

For leases with an effective date in or after February 2021, where the relevant rent is between £9,000 and £13,500, you’ll need to contact us for a calculation.

Read our announcement or our guidance on the LTT rates and bands changes announced in December.

This calculator can help you work out how much Land Transaction Tax (LTT) you need to pay if you buy property or land over a certain price in Wales.

This is for transactions in Wales completed on or after 1 April 2018.

The calculation is based on the tax rates and bands approved by Welsh Parliament. 

Before you start

If you already own 1 residential property or more, you may need to pay the higher residential rate. If you're replacing your main residence, higher rates may not apply. See our guide to higher rates

This calculator is a tool to help you assess the tax you need to pay for most transactions in Wales. It is your responsibility to make sure that the information in your return is accurate.
