stamp duty
noun /ˈstæmp djuːti/
/ˈstæmp duːti/
[uncountable]- a tax in the UK on some legal documentsCultureIn the past, stamp duty was paid on documents used to transfer houses and flats from one person to another. In December 2003 this was replaced by a 'Stamp Duty Land Tax' (SDLT). This tax is paid directly to the government rather than by paying for a document to be stamped. The amount depends on the value of the property bought. The tax is often still referred to as ‘Stamp Duty’.
