Australian financial year calculator
See which financial year a date falls in, and how many days remain in the current year.
What the result means
The Australian individual income year runs from 1 July to 30 June. 30 June 2026 is still 2025–26; 1 July 2026 is the first day of 2026–27. Tax brackets, HELP thresholds and the superannuation guarantee all attach to that year, not to the calendar year.
How it is calculated
If month ≥ July, FY starts this calendar year; otherwise it started last 1 July
- FY label: Start year–last two digits of end year, for example 2026–27.
The bounds are always 1 July through 30 June inclusive.
Assumptions
- Standard individual income year. Not a substituted company year.
Worked example
19 August 2026
Today in the Phase 2 build.
- Month
- August is after June
- FY
- 2026–27, ending 30 June 2027
Tax on that year’s resident salary uses 2026–27 rates.
Why the label looks like two years
“2026–27” means the year that starts on 1 July 2026 and ends on 30 June 2027. Nothing in the label is a tax rate. It is only a name for those 365 or 366 days. A pay, a bonus or a deductible expense is assessed in the year of the date it belongs to, which is why 30 June and 1 July are not interchangeable.
The financial year guide walks through what actually changes on 1 July — resident brackets, Medicare shade-in, HELP thresholds and the superannuation guarantee — and when self-lodgers ordinarily have to lodge.
Companies and substituted years
Some companies use a substituted accounting period that does not end on 30 June. That is a corporate reporting choice. It does not change the individual income year for an employee of that company. Your PAYG summary and your tax return still run from 1 July to 30 June.
Questions
When do I lodge?
If you lodge yourself, the ATO’s ordinary due date is 31 October after the year ends. Registered agents lodge later under a lodgement program. This page only names the income year a date belongs to.
Does a 30 June payday belong to the new year?
No. 30 June is the last day of the old year. 1 July is the first day of the new one. A bonus paid on 30 June 2026 is 2025–26 income.
Which year do the other OzCalc tax tools use?
The default is 2026–27. Where a second year is available you can switch, and each page shows the ATO source and the review date.
