67.This section effects the transfer to Treasury Ministers and the Inland Revenue of policy functions of the Secretary of State in relation to contributions and the NIF. The transfers are to come into effect from an appointed day.
68.In tax legislation, regulation-making functions are generally reserved to the Treasury where they affect matters such as the existence or size of a tax liability. Regulation-making powers relating to administrative functions are generally transferred to the Board of Inland Revenue. This Act provides for the same general divide in relation to contributions. So the regulations relating to policy functions transferred would be made by the Treasury, although the Inland Revenue would be responsible both for advising Ministers on policy and for its operational implementation.
