Calculate your commercial stamp duty

We recommend using our commercial stamp duty calculator to check the stamp duty rates so you know exactly what you’ll have to pay and there are no surprises during your next property purchase.

The stamp duty you have to pay depends on the property’s price and you have to pay stamp duty if you buy a property costing more than £500,000 (£15,000 for additional homes).

If you're a first time buyer you may not need to pay stamp duty, find out more here.

The stamp duty calculator presumes that none (or part) of the property qualifies as mixed-use for which the current SDLT would be 4%.

Please note that this tool is an indicator only, your solicitor or tax consultant will advise you as to the actual stamp duty land tax that must be paid on completion.

All calculations are based on new temporary rules as of 8th July 2020, which are subject to change at any time.
