Methodology and sources
Every calculator runs in your browser from a rate file for each financial year. Nothing you enter is sent to us.
Update process
- Each June we update the rate files for the new financial year from ATO, Fair Work and state revenue office publications.
- Automated tests check results against published worked examples (for example, a $80,000 salary in 2026–27: $14,520 tax, $1,600 Medicare levy, $63,880 take-home).
- Rates were last checked on 26 September 2026.
- Found an error? Tell us. We correct errors and note significant corrections on this page.

Known limitations
- 2026–27 Medicare levy low-income thresholds are not yet published, so 2025–26 thresholds are used.
- 2026–27 foreign resident and working holiday maker assessment rates are not yet published by the ATO. We use 2025–26 rates, which match the 2026–27 withholding schedule.
- Only offsets shown in each calculator are included.
