About
About Payroll Tax by State
What this site is, what it publishes and how it is paid for.
Payroll Tax by State is an independent publication, part of a small network of websites that turn official data into plain-language guides and tools. This site puts the payroll tax rules of Australia's eight states and territories side by side and estimates the tax with the formulas they publish. It exists because each revenue office explains its own rules well, but none compares the states or shares a threshold across several of them in one tool.
We are not a government website, a tax agent or an accounting firm, and we are not linked to any revenue office or software company. The site gives general information, not tax advice.
What we publish
- Only figures we have read on an official page or in the legislation, each linked to its source with the date we checked it.
- Formulas taken from the revenue offices and the payroll tax Acts, tested against every official worked example we could find.
- Where an official source cannot be read, or the law leaves a case open, we say so instead of filling the gap.
How the site is paid for
The site shows advertising served by Google AdSense. Google's automatic placement decides where ads appear on a page; the space we reserve for ads comes after the calculator. In future the site may link to payroll software through partner programmes; any such link will be labelled, and partners will never decide what we publish or change a figure.
Your data
The calculator runs entirely in your browser: the wages you type are not sent to us or to anyone else. See the privacy page.
Corrections
Rates change every 1 July and sometimes mid-year. We re-read every official source on a schedule and before each update. If you spot an error, use the corrections form: we check it against the official source and fix the page.
General information, not tax advice. Figures and formulas are taken from the official revenue office pages and legislation linked on each page. Payroll tax depends on facts this site cannot check (what counts as wages, exemptions, grouping, contractors). Confirm your liability with the revenue office of each state where you pay wages, or with a registered tax agent.
