The training requirement

Policy matters

Responsibility for policy remains with CTIS at 100 Parliament Street. Enquiries on policy matters should, however, be referred in the first instance to the Technical Adviser.

HM Revenue & Customs, its Commissioners and officers

Where there is a provision for the making of regulations by HMRC, FA00/SCH22/PARA145 restricts this to the Board of Inland Revenue. Under section 13(3)(a) of the Commissioners for Revenue & Customs Act 2005 this function is now reserved to the Commissioners for Revenue & Customs.  Elsewhere in Schedule 22 and the regulations, the reference to (the former) ‘Inland Revenue’ includes any officer (section 13(1)).  However, certain functions should not be exercised without first referring to the Tonnage Tax Technical Adviser.  These include:

* Giving clearance to a foreign company or group TTM02060
* Exchange of information with DfT TTM04030
* Considering exclusion for exceeding 75% limit on charters-in TTM05300
* Considering exclusion for tax avoidance TTM05520
