Where the numbers come from
Every figure is read from the body that actually sets it — ATO, Revenue NSW, State Revenue Office Victoria, Queensland Revenue Office, RevenueSA, RevenueWA, State Revenue Office of Tasmania and ACT Revenue Office — and each calculator names its sources, with the date they were last checked where we have one on record, so you can check us.
These are estimates, not advice. Your own allowances, reliefs and circumstances can move the number, and every finance page says so where you'll see it. How we check our figures.
What these calculators cover
The Australian calculators follow the 2026–27 financial year: resident tax rates with the Medicare levy, the low income tax offset and HELP repayments, super on top, GST at 10% with the divide-by-11 reverse, and transfer duty in every state and the ACT with first-home concessions.
Not modelled: foreign residents and working holiday makers, who use different rate scales; the seniors and pensioners tax offset; family Medicare levy and surcharge thresholds, which need a spouse's income; deductions and other offsets; and Northern Territory stamp duty.
