What is Australian Income Tax?

Australian Income Tax is a system of taxation where individuals pay a portion of their earnings to the Australian government. The amount of tax paid is determined by a person's taxable income and residency status. Australia uses a progressive tax system, meaning that the tax rate increases as the taxable income increases.

The Australian Income Tax Formula

The general formula for calculating Australian income tax is:

Tax=i=1n(Incomei×Ratei)

Where:

  • Incomei = Taxable income in bracket i
  • Ratei = Tax rate for bracket i
  • n = Number of applicable tax brackets

Step-by-Step Tax Calculation

  1. Determine the individual's residency status (resident or non-resident).
  2. Identify the applicable tax brackets and rates based on residency status.
  3. Calculate the tax for each bracket where income falls: Taxbracket=(IncomeinbracketLowerthreshold)×Ratebracket
  4. Sum up the tax from all applicable brackets to get the total tax.
  5. Calculate the effective tax rate: EffectiveRate=TotalTaxTotalIncome×100%

Example Calculation

Let's calculate the income tax for an Australian resident with an annual income of $85,000:

  1. $0 - $18,200: 18,200×0%=$0
  2. $18,201 - $45,000: (45,00018,200)×19%=$5,092
  3. $45,001 - $85,000: (85,00045,000)×32.5%=$13,000
  4. Total Tax: $0+$5,092+$13,000=$18,092
  5. Effective Tax Rate: 18,09285,000×100%=21.28%
