Inheritance tax is charged when an estate is passed from a deceased individual to any number of beneficiaries.
Inheritance tax is due within six months after a donor's death, at which point interest will accrue based on the Bank of England rate if it's not paid.
Inheritance tax is paid directly to HM Revenue & Customs (HMRC) by the executor of the will, or the legal representative involved in distributing the estate - not the beneficiary of the estate.
Inheritance tax due is paid to HMRC via a direct transfer of fund, or by selling off property equity or possessions to meet the total value owed.
