Stamp Duty is charged using a banded tax system, meaning different portions of the property’s value are taxed at different rates.

Rather than paying one percentage on the full purchase price, each price band is taxed separately.

The general calculation is:

Stamp Duty = Tax payable across each SDLT threshold

Additional property purchases and certain buyer categories may attract higher rates or qualify for specific reliefs.
