Stamp Duty Calculator

A handy tool to work out how much you'll need to pay.

Stamp Duty Land Tax (SDLT) is a lump sum tax that has to be paid on all property transactions in England, Wales and Northern Ireland which have a purchase price above £125,000. The tax applies to houses, flats, land and other buildings and the amount you have to pay is based on the property’s value at the time of purchase.

So what is it all about?

In December 2014 the Chancellor announced major reforms to stamp duty. Prior to the change a uniform tax rate was applied to the whole purchase price - with that rate determined by the price of the property. Under the new system the amount of tax paid on a house purchase will be tiered, like income tax, with the rate varying according to the different tax thresholds covered by the property price. It means that in many cases buyers are paying less stamp duty and are avoiding the sudden jumps in stamp duty that previously took place between the price thresholds. The new rates are:

Purchase price
of property
Rate of SDLT
percentage of portion of purchase price
£0 - £125,000 0%
£125,001 - £250,000 2%
£250,001 - £925,000 5%
£925,001 - £1.5 million 10%
Over £1.5 million 12%

There is no tax on the first £125,000 for any of the properties under the new system. Add together the percentages as the property prices increase to see what the stamp duty will be; for example, a £350,000 property will generate £7,500 in stamp duty, calculated in the following way:

£0 - £125,000 0% £0
£125,001 - £250,000 2% + £2500
£250,001 - £350,000 5% + £5000
Total Stamp Duty due  = £7500

Stamp duty has to be paid within 30 days from the date of completion - when all the contracts are signed and is usually paid through your solicitor. To find out how much you would have to pay under the new system, and to compare against the previous one, use our stamp duty calculator above.

For those looking to purchase an additional property as a buy to let or second home, there will be a surcharge of 3% on each stamp duty band from April 2016.
