Stamp duty calculator

Calculate your SDLT payable following the changes introduced in the 2016 Budget.

June 01, 2017

The 2016 Budget brought changes to the stamp duty land tax (SDLT) rates payable by purchasers on freehold commercial property and leasehold premium transactions. These changes took effect from 17 March 2016.

Under the reforms SDLT is now payable on the portion of the transaction value which falls within each tax band. Previously the SDLT band applied to the whole transaction value. Under the reforms buyers of commercial property worth up to £1.05m will pay less in stamp duty.​

This calculator determines the SDLT payable following the changes introduced in the 2016 Budget.
