Particular features of the 2013 edition include: Seven parts: overview and structure, principles of income, deductions and offsets, timing issues, investment and business entities, tax avoidance and administration, and indirect taxes; clearly structured chapters within those parts grouped under helpful headings; flowcharts, diagrams and tables, end of chapter practice questions, and case summaries; an appendix containing all of the up to date and relevant rates; and the online self-testing component mentor, which provides questions for students of both business and law. Every major aspect of the Australian tax system is covered, with chapters on topics such as goods and services tax, superannuation, offsets, partnerships, capital gains tax, trusts, company tax and tax administration. All chapters have been thoroughly revised.
