In a Treasury media release dated 25 February 2026, headline inflation was reported at 3.8% and underlying inflation at 3.4% through the year to January 2026.

Why this matters for tax outcomes

Persistent inflation can shift tax results even when rates are unchanged:

  • nominal pay rises can increase withholding and annual tax payable
  • business input cost pressure can tighten margins and affect PAYG settings
  • higher living costs can increase pressure to access deductions, where records must still meet ATO standards

Practical checklist

  1. Compare this year’s expected taxable income against last year’s withholding pattern.
  2. Review deductible expense records now, not just at year-end.
  3. Revisit salary packaging and super contribution settings if take-home cash is under pressure.
  4. Update quarterly tax cash-flow forecasts where costs are rising faster than revenue.

Timing reminder

Rate settings may be stable while inflation remains elevated. That gap is where many taxpayers misread their likely year-end position.
