1. Key Ideas

Calculate taxable income by identifying gross income and subtracting only the deductions that are genuinely allowable.

  • The formula: taxable income = gross income − allowable deductions
  • Why tax is applied to taxable income, not gross income

2. Success Criteria

By the end, you should be able to:

  • The formula: taxable income = gross income − allowable deductions
  • That gross income includes all assessable income (salary, interest, rental income)
  • Examples of allowable and non-allowable deductions

3. Key Terms

Taxable IncomeGross income minus allowable deductions — the amount on which tax is calculated.
Gross IncomeTotal income from all sources before any deductions.
Allowable DeductionWork-related expenses that can be subtracted from gross income to reduce taxable income.
Tax OffsetA reduction in the amount of tax payable, also called a tax rebate.
Medicare LevyA 2% levy on taxable income to fund the public health system.
