Where CDF offer is made 30 June 2014 onwards: managing the detailed disclosure process: timescale for submission of detailed disclosure report
If it is clear at the initial meeting who will be preparing the disclosure report, the investigator should try to agree a timescale for its submission. There is no fixed period.
A very detailed report is not necessary in every case. For example, in a very simple case (simplicity and size are quite distinct) this may require only a short period - perhaps even weeks - for a perfectly adequate report to be produced.
Most cases will be more complex and inevitably require longer. We should always seek a period of no more than six months, but six months should not be viewed as standard. Each case must be considered on its merits. A lot depends on whether the concerns under investigation relate to direct tax, indirect tax or both. Investigators must listen to any representations made by customers and their advisers. A reasonable approach must be taken so that it is not possible for a customer to subsequently argue that their incomplete disclosure was brought about by the unreasonable deadline set by HMRC.
It will be exceptional to agree a timescale for a disclosure report that goes beyond six months and this should only be done with the written agreement of your Authorising Officer.
There will be cases where nothing more than a very general indication of the nature or quantum of the irregularities has been given in the Outline Disclosure. Additionally the customer might not have been able to give any more information at any subsequent meeting where this has been discussed. In this type of situation Investigators should be particularly aware of the need to monitor progress very closely. This will also be the case where all that is disclosed in an Outline Disclosure and any subsequent meeting, are matters previously disclosed to HMRC officers, and you suspect that the customer is understating the true extent of the problem.
