Find out if a postcode is in Wales for LTT

Use our postcode checker for LTT to check whether the postcode of the land or property that’s being bought or leased is in Wales.

This will help you to decide if a return needs to be filed with us.

Calculate LTT with multiple dwellings relief (MDR)

MDR can be claimed when property in Wales is bought from the same seller, in the same transaction (or linked transactions), if it’s made up of more than 1 dwelling.

To help work out the tax due on transactions if claiming MDR, including a number of linked transactions, we’ve an interim MDR spreadsheet calculator on our website.

To find out when MDR could apply to a transaction, use our MDR quick guide or watch our short MDR explainer videos.

The calculator is in beta-phase. Please give feedback to help us improve it.

User research

We're always looking to make our services easier to use. Sign up to join our user feedback group and help us improve by emailing:

We’re developing ways to make transactions that may be entitled to MDR easier to file. We’re developing an online calculator similar to our tax calculator and higher rates checker. Also, we’re amending the LTT return to help you file MDR transactions correctly.

These improvements will help us both to save the time and expense of reviewing transactions that have already been filed. To make these changes work we need your help as you use our system every day.

Penalties for late filing and for paying tax late

We want to make sure that the tax system in Wales is fair to help the right amount of tax to be paid at the right time.

If LTT must be paid, and the deadlines and requirements are not met, we may charge a penalty.

A penalty may need to be paid if the LTT return is filed late or the tax bill is paid late.

To find out more about tax penalties for LTT, how this is calculated and what you can do, please read our penalties guidance.

  • non-residential
  • mixed use

Watch our short mixed use explainer video which includes 6 business tests to help you decide.

We also have a non-residential and mixed use quick guide.

LTT calculator improvements

Based on user feedback, we made improvements to our LTT calculator. The calculator is now quicker and easier to use.

We also updated the calculator’s URL. If you use the previous URL it’ll redirect. The GOV.WALES start page for the calculator has not changed. To avoid confusion, we recommend that you always use the LTT calculator start page on GOV.WALES instead of the first screen of the calculator.

We’ve also updated the higher rates checker URL. If you use the previous URL it’ll redirect. We recommend that you use always use the higher rates checker start page on GOV.WALES.
