Stamp Duty Calculator

Stamp Duty Land Tax (SDLT) must be paid to HM Revenue and Customs when buying a residential property or land over a certain price in England, Wales and Northern Ireland.

Up until December 2014 Stamp Duty rates were based on a 'slab' system, with the amount being a percentage of the whole of the purchase price, with the total property value defining the percentage band. This system resulted in steep increases in stamp duty at the band thresholds and was thought to have a distorting effect on house prices.

Since December 2014 the rates are calculated using a cumulative banding system whereby a certain percentage is due on the amount of the property value above banded thresholds, resulting in a smooth increase in SDLT as the property price increases.

In April 2016 an increase in SDLT was applied to certain purchases, eg second-homes, resulting in a 3% higher rate across all bands.
