What is Stamp Duty?

Stamp Duty, more formally known as Stamp Duty Land Tax (SDLT) is the tax you pay when you buy a property over a certain price. It varies by country in the UK. In Scotland, you’ll pay Land and Buildings Transaction Tax (LBTT) instead of Stamp Duty, while in Wales you’ll pay the Land Transaction Tax (LTT).

How much is Stamp Duty?

If you’re a first time buyer, you will only pay Stamp Duty on properties costing more than £425,000. For second time buyers, you will pay Stamp Duty on properties costing more than £250,000.

The amount you pay is based on the Stamp Duty tax bands. The tax is calculated on the portion of the property price that falls into each band. For example, if you bought a 450,000 house as a second time buyer, you would not pay any Stamp Duty on the first £250,000. On the remaining £200,000 you would pay 5%, which would be £10,000.

These Stamp Duty bands only apply to properties in England and Northern Ireland. For properties in Scotland and Wales, you’ll pay different rates.


The results from the Stamp Duty calculator is intended as guidance to give an indication of stamp duty liability for residential property purchases in England and Northern Ireland. The results from the calculator are subject to change depending on tax rules and results may vary depending on individual circumstances.

When do you pay Stamp Duty?

Once you have completed on your property, you will have 14 days to file a Stamp Duty Land Tax (SDLT) return and pay any Stamp Duty due. If you don’t submit a return and pay the tax within 14 days, you may be charged additional penalties and interest by HMRC.
