Why trust these numbers

Every rate and threshold on AussieCalcs comes from an official source: the ATO, state revenue offices, Fair Work or Treasury. Each figure is recorded with a link and a verification date, re-checked every 1 July and after every budget, and each calculator shows exactly how it reached its answer.

AussieCalcs is built and maintained by Planometric, a software developer in Melbourne, Australia. Read the editorial policy or the about page. If a number looks wrong, report it and it gets fixed and noted.
