Specialist Investigations Operational Guidance

Introduction and organisation: recording information: preserving confidentiality

You should be aware that people can infer from SI’s involvement in a case that someone or some entity has serious tax problems. It is therefore essential that there is no inadvertent breach of confidentiality. You must preserve the taxpayer’s confidentiality by ensuring that letters are properly addressed and that letters, documents, and so on are faxed to the correct number. Letters must be headed ‘Private and Confidential’. If a fax is sensitive or personal it must go to the right individual so it is best to phone beforehand to make sure that someone is available at the other end to pick it up. If in doubt, you should send the correspondence in a more secure way. For more information on confidentiality you should refer to the Information Disclosure Guidance found in the Intranet Library
