Changelog

Updates, corrections, and improvements to auincometax.com.

v2.2FixOctober 2026
  • –HECS/HELP: the homepage FAQ, the homepage quick-facts panel, the glossary and the About page still described the old system (first threshold about $58,518, rates from 1% to 10% on the whole income). They now show the ATO 2026-27 table: nil up to $69,528, 15c for each $1 above that up to $129,717, then $9,028 plus 17c for each $1 up to $186,050, and a flat 10% of total repayment income above $186,050.
  • –The calculator and the HECS-HELP page already used these figures. The 2026-27 thresholds are no longer estimates: they were checked against the ATO table (page updated 30 June 2026).
  • –The HECS notes in v2.0 and v1.3 below are superseded by this entry: the repayment has been marginal since 1 July 2025, except for the flat 10% top band.
v2.1FixOctober 2026
  • –Salary pages: the comparison with typical earnings used an unsourced figure of $90,000. It now uses the ABS average full-time adult ordinary time earnings for May 2026 ($2,083.70 a week, about $108,352 a year) and says "average", because the ABS figure is a mean, not a median.
  • –Methodology: added the ABS Average Weekly Earnings release to the list of primary sources.
v2.0Major updateJuly 2026
  • –Updated all resident, non-resident, and working holiday maker tax rates for 2026-27.
  • –Implemented Stage 3 tax cuts: resident 19% bracket reduced to 15% from 1 July 2026.
  • –Checked working holiday maker rates for 2026-27 against ATO Schedule 15: 15% to $45,000, then 30%, 37% and 45% (the 30% rate has applied since 2024-25).
  • –Updated Superannuation Guarantee rate to 12% (effective 1 July 2025).
  • –Added Working Holiday Maker dedicated page and calculator.
  • –Added salary sacrifice input (pre-tax super contributions).
  • –Updated HECS/HELP repayment thresholds (estimated from 2024-25 + CPI indexation — pending ATO confirmation of final 2026-27 figures).
  • –Added Medicare Levy Surcharge (MLS) thresholds for 2026-27.
  • –Added Methodology, About, Tax Disclaimer, Glossary, Changelog, and Contact pages.

v1.3FixOctober 2025
