What tax obligations do sole traders have?

Understand the main tax obligations sole traders may need to consider, including income tax, GST, PAYG instalments, deductions, and records.

Summary

Sole traders generally need to report business income in their individual tax return, keep records, claim only allowable deductions, and consider whether registrations such as GST apply. Depending on their circumstances, sole traders may also need to manage PAYG instalments and other business tax obligations.

What this means

A sole trader has fewer structural obligations than a company, but tax responsibilities still matter. The main areas usually include income reporting, deduction records, business registrations, GST if required, and tax payment planning.

The specific obligations depend on the business activity, turnover, income level, whether the sole trader has workers, whether GST applies, and whether the ATO places the taxpayer into PAYG instalments.

Typical actions

  • Report business income in the individual tax return.
  • Keep records of income and expenses.
  • Check whether GST registration is required.
  • Check whether PAYG instalments apply.
  • Keep deduction evidence.
  • Review obligations if hiring workers or contractors.
  • Speak with a registered tax agent for complex situations.
