About AusTax Tools

AusTax Tools is an independent website focused on practical Australian tax calculators and plain-English tax explainers.

What we publish

How calculator logic is maintained

Calculator formulas are implemented in code and reviewed against public ATO and state revenue references. When rates or thresholds change, we update calculation constants and publish updated pages.

You can also review our reference datasets under Tax Data Assets.

How content is prepared

Each guide is written for informational use and checked against primary sources such as ATO guidance, legislation references, and state revenue office materials where relevant.

For detailed publishing standards, see our Editorial Policy.

Important limitations

This site does not provide personal tax advice. Results are estimates based on information entered and the assumptions shown on each page.

For advice tailored to your circumstances, speak with a registered tax agent.
