About This Calculator
Who built it, how it works, and what it is not.
Who's behind this
I'm Borja Pérez, and I built and maintain auincometax.com. I'm not an Australian tax agent — I built this tool because I kept needing a quick, honest way to estimate take-home pay in Australia and couldn't find a calculator that made its sources clear or its assumptions easy to check. So I built one, sourced every rate directly from the ATO, and published exactly how it calculates on the Methodology page.
You can also find me on LinkedIn or write to borja@auincometax.com.
If you spot something that looks wrong, or you just want to ask a question about how a figure was calculated, you can reach me directly via the contact page. I read every message myself.
What is auincometax.com?
auincometax.com is a free, independent Australian income tax calculator for the 2026-27 financial year (1 July 2026 – 30 June 2027). It calculates estimated take-home pay, income tax, Medicare Levy, HECS/HELP repayments, and employer superannuation for Australian residents, non-residents, and working holiday makers.
I built it for people who want a quick, clear estimate of their net pay — employees, job seekers comparing offers, contractors, students, recent graduates, and anyone moving to or within Australia.
Data sources and accuracy
All tax rates, thresholds, and offsets are sourced directly from the Australian Taxation Office (ATO) and the Australian Treasury. I cite the specific ATO pages used on the Methodology page.
The 2026-27 HECS/HELP repayment thresholds come from the table the ATO published for 2026-27 (nil up to $69,528, then marginal rates). Any figure that is still an estimate, such as the Medicare levy shade-in range, is marked as one on the page where it appears.
Results are estimates only. They do not account for all individual circumstances, salary sacrifice arrangements not entered by the user, tax agent deductions, fringe benefits, investment income, or other complex situations. Always confirm your tax position with a registered tax agent or the ATO's own tools.
