Our tools help Australians estimate income tax and take-home pay, understand marginal rates, and explore how Medicare, HELP, offsets, deductions, and pay frequency affect an estimate.
About
Who publishes Income Tax Calculator, what it provides, and how its work is maintained.
Last updated: 28 July 2026
Who publishes this website
Income Tax Calculator is published and maintained by MoneyToolkit, an independent Australian publisher of practical financial calculators and plain-English guides.
MoneyToolkit is responsible for the calculators, editorial content, updates, and corrections on this site. We use a publisher identity so the work is accountable without requiring an individual contributor to make their personal identity public.
We are not affiliated with the ATO, a payroll provider, employer, accounting practice, lender, or financial adviser. Advertising does not influence results or editorial conclusions.
What we build
The site includes the main income-tax calculator plus pay-frequency, hourly-rate, bonus, second-job, contractor, marginal-rate, bracket, and year-comparison tools.
They are designed for employees, job seekers, contractors, households, and taxpayers checking a general salary or tax scenario.
Sources you can inspect
We prioritise ATO guidance and rate tables, Commonwealth tax and Medicare legislation, official HELP rules, and published government thresholds.
Reviewed when inputs change
We prioritise review when tax brackets, offsets, Medicare or HELP rules, official guidance, or calculator logic changes.
Private by design
Calculator inputs are processed in your browser. You can use the tools without creating an account or sending the values you enter to us.
How to assess our work
Read the calculator methodology for the model, assumptions, and sources, and the editorial policy for our sourcing, review, and independence standards. If something appears wrong or out of date, the corrections policy explains how to report it.
Important limitation
A final tax assessment depends on residency, income sources, deductions, offsets, private health cover, family circumstances, reportable amounts, and other facts a general calculator cannot fully capture.
