This report provides an in-depth analysis of taxation principles and planning, focusing on current issues in Australian tax law. It examines the Multinational Anti-Avoidance Law (MAAL), the Diverted Profits Tax (DPT), and Country-by-Country (CbC) reporting, which are key components of Australia's efforts to combat tax avoidance by multinational corporations. The report explains the objectives, mechanics, and application of MAAL, including its intent to counter the erosion of the Australian tax base through artificial arrangements. It also details the aims and mechanics of DPT, designed to prevent the diversion of profits offshore, and explores the objectives and scope of CbC reporting, which aims to provide tax administrations with a higher-level overview of multinational enterprises' operations and tax risk profiles. The report concludes that MAAL has the potential to efficiently fight multinational tax avoidance, while DPT is likely to be readily implemented, though it is more complex and has faced criticism. This report is a valuable resource for students seeking to understand contemporary tax challenges and the measures being taken to address them.
