Sources and assumptions
Data Sources and Calculation Assumptions
How Oz Pay Check approaches Australian pay, tax, superannuation, HECS/HELP, Centrelink and finance calculator assumptions.
Oz Pay Check is an independent calculator website. It is not affiliated with the Australian Taxation Office, Services Australia, Centrelink, myGov, Fair Work or any Australian Government department. Results are estimates only.
Tax and pay settings
Australian income-tax year settings are used where available.
Medicare, HECS/HELP and superannuation options are shown separately where calculators support them.
Salary, hourly, weekly and fortnightly pages are designed to explain the same result in practical pay periods.
Centrelink estimates
Centrelink pages are estimate tools only, not Services Australia decisions.
Payment examples may depend on income, partner income, rent, children, assets and reporting periods.
Users should confirm payment eligibility and reporting rules directly with Services Australia.
Limitations
The calculators cannot cover every offset, concession, surcharge, payroll arrangement or personal situation.
Important decisions should be checked with official sources or a qualified professional.
If a possible error is found, users can report the page and scenario through the contact page.
