How Stamp Duty works
Stamp Duty Land Tax, usually shortened to SDLT, may be payable when you purchase property or land in England or Northern Ireland.
SDLT is calculated progressively. Different portions of the purchase price can be taxed at different rates.
Eligible first-time buyers can benefit from different SDLT thresholds on qualifying purchases.
Higher SDLT rates can apply when you purchase an additional residential property.
How we estimate your Stamp Duty
The calculator divides the property price into the relevant SDLT bands and applies the appropriate tax rate to each portion.

What is Stamp Duty Land Tax?
Stamp Duty Land Tax is a tax that may be payable when buying property or land in England or Northern Ireland.
Do first-time buyers pay Stamp Duty?
Eligible first-time buyers can receive SDLT relief. For a qualifying purchase of £500,000 or less, the first £300,000 is charged at 0% and the portion from £300,001 to £500,000 is charged at 5%.

First-time buyer relief is not available when the purchase price exceeds £500,000. Standard residential rates are then normally used.
