This assignment examines the tax implications of two income streams for a taxpayer in Australia: a $100,000 annual salary and a $400,000 joining bonus from a new television network. It applies relevant sections of the ITAA 1997 to determine if both payments are considered assessable income, using case law like Smith v FCT (1987) as supporting evidence. The analysis concludes that both payments fall under assessable income categories and explains the reasoning behind this classification.
