IHTM09381 | Obtaining mandates: introduction

From HM Revenue & Customs · Inheritance Tax Manual

If possible, you should obtain a mandate from the taxpayer under enquiry before contacting the third party.

There are two forms of mandate

  • a mandate for enquiries of banks and building societies (there is background information on when and how to approach banks directly at )

  • a mandate which, suitably amended if necessary according to the facts of the case, may be used for other enquiries of third parties ().

If you cannot get a mandate from the taxpayer you should first approach the third party on an informal basis. If you need to consider issuing an information notice () under to a bank or building society you should consult Litigation before taking any action.

You should make the taxpayer aware that the bank may charge them for the information provided.
