From HM Revenue & Customs · Specialist Investigations Operational Guidance
Here are some guidelines for what you should include in an SI investigation file:
The external correspondence file should contain copies of all outgoing and the originals of all incoming correspondence, including:
clear evidence of to whom copy letters have been sent
exactly what information has been faxed to whom and exactly when.
Notes of telephone calls with taxpayers and, where appropriate, their advisers. These should be placed in the external correspondence file.
Notes of all telephone conversations or meetings with colleagues in local offices, technical experts, Solicitor’s Office, and so on. These should be put in the internal correspondence file (see TTOG10010 - Appendix 2).
Where letters, and so on include attachments, which are filed separately; this should be clearly referenced on both sets of papers.
Notes of any meeting held either with a taxpayer and/or the adviser. They should record the substance of what was said and what was agreed. The notes must be circulated and agreed.
Notes of meetings must meet the highest standards, for further guidance see SIOG1700.
Hard copies of all emails sent in relation to the case. Copies of all emails should also be retained in the electronic case folder for that case.
