Calculate Land Transaction Tax with multiple dwellings relief

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

For more complex cases including linked transactions, or if you're uncertain how the tax or relief applies:

• use our MDR technical guidance
• watch our short explainer videos on calculating with MDR
