About AusTax Tools
AusTax Tools is an independent website focused on practical Australian tax calculators and plain-English tax explainers.
What we publish
- Interactive calculators for income tax, CGT, GST, payroll tax, and property taxes.
- Scenario pages that compare common tax decisions side by side.
- Tax insights articles that explain rules, thresholds, and timing decisions.
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.
