As a solicitor or conveyancer, use this calculator to help work out the tax due on transactions if claiming multiple dwellings relief (MDR).

The relief can be claimed where a taxpayer buys more than one dwelling in Wales (multiple dwellings) from the same seller either:

  • in a single transaction with the same effective date
  • in a number of linked transactions

You’ll need to know:

  • if main rates or higher rates of the tax apply
  • the total purchase price for all dwellings
  • the number of dwellings involved
  • the total purchase price for all other land
