SolvedIHTM31751 | Assessing: deposits: introduction
From HM Revenue & Customs · Inheritance Tax Manual
A deposit is a sum of money
placed by the taxpayer
with HMRC
against a possible liability to Inheritance Tax
to stop interest from accruing on that sum.
When you receive a deposit, file it inside the file cover and note the details. If your registry staff enter the details, they will notify you of the deposit so you can consider how to deal with it.
