Who Needs to File a Tax Return in 2025?

Here’s a list of people who generally need to lodge a tax return in Australia:

  • Anyone who earned taxable income over the threshold ($18,200)
  • Individuals who had tax withheld from any job or Centrelink payments
  • Sole traders or freelancers
  • Property investors with rental income
  • Investors in shares, ETFs, or cryptocurrency
  • Individuals with foreign income
  • Trustees of Self-Managed Super Funds (SMSFs)

The ATO is also increasing scrutiny on capital gains declarations, particularly targeting ‘wash sales’, a strategy where investors sell and repurchase assets like shares or crypto solely to trigger artificial capital losses.
