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
- Compare this year’s expected taxable income against last year’s withholding pattern.
- Review deductible expense records now, not just at year-end.
- Revisit salary packaging and super contribution settings if take-home cash is under pressure.
- 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.
