Stamp Duty Land Tax (SDLT) is a progressive tax on property purchases in England and Northern Ireland. Rates are applied in bands — you only pay each rate on the portion of the price that falls within that band.
Investment properties and additional dwellings pay an extra 5% surcharge on all bands. Companies buying residential property over £500,000 face a flat 15% rate.
