The summary of this report says:
This note suggests that:
The UK should create an Office for Tax Responsibility (OTR).
This OTR should report to the House of Commons Public Accounts Committee so that it might hold HM Revenue & Customs, HM Treasury and the Chancellor of the Exchequer to account for their management of the UK tax system.
The Office for Tax Responsibility should be responsible for preparing annual assessments of the UK tax gap and tax spillovers.
Presumably to be run by Britain’s foremost retired accountant and expert in the tax gap and tax spillovers?
