IHTM14835 | Lifetime transfers: associated operations: transfer in stages
From HM Revenue & Customs · Inheritance Tax Manual
A transfer may be effected in a series of stages. Typically successive portions of a property may be transferred, often annually. The portion may be calculated in a variety of ways: often it is a share equivalent in value to the amount of the annual exemption. This is sometimes referred to colloquially as ‘salami slicing’ (IHTM14161).
