This course deals with the taxation of companies, partnerships and trusts, the key structures for business and investment in Australia. This comparative treatment emphasises a coherent understanding of the tax structures and a critical appreciation of the reasons for them. The Ralph proposals for a unified entities regime highlight the divergences. The course deals with practical problems arising from concepts of legal personality (or the lack of it), dual tax at the entity and member level, including the various distribution rules and operation of company franking mechanisms. Students should have completed or be enrolled in ATAX0009 The Law of Companies, Trusts and Partnerships.
