Australian residents pay income tax on all forms of income, after a tax-free threshold of $18,200. Tax is calculated at four different rates according to how much income you earn each year, and the tax rate increases the more you make.

To protect the security of your tax and super information, the ATO is introducing a new process to ensure that only your authorised tax agent, BAS agent or Payroll service provider can access your account and act on your behalf.
