Is a compliance check meeting actually compulsory?
No. In an ordinary civil compliance check, HMRC has no statutory power to force you to attend a meeting. Schedule 36 Finance Act 2008 gives HMRC power to require documents and information, but it doesn't give a power to compel physical attendance at an interview in the way, for example, a criminal interview under caution would.
HMRC's opening letters often propose a meeting as the natural next step, and many advisers do agree to one because it can speed things up. But it remains a request rather than a demand, and declining it, at least in a standard civil check, carries no direct penalty.
