Australian compliance calendar 2026–2027: every deadline you need
A month-by-month list of every major Australian compliance deadline for 2026 and 2027 — tax, super, AML, privacy, climate, WHS, modern slavery. Free .ics download.
How to use this calendar
This is the reference index. Every entry below links to the underlying Rules Mate obligation page (with source citations) or regulator guidance. Bookmark the page or subscribe to the live .ics feed so new and changed deadlines flow into your calendar automatically.
Three filters worth applying:
- Jurisdiction — most deadlines are Commonwealth, but state taxes (payroll, land, stamp duty) and state WHS notifications have their own cycles.
- Entity type — large entities (ASRS Group 1, WGEA ≥100 emp, Modern Slavery ≥$100M) face deadlines small businesses don't.
- Industry — financial services, NDIS providers, RTOs, AHPRA-registered practitioners and aged care have sector-specific cycles on top of the universal ones.

Frequently asked
Is this calendar comprehensive?
It covers every major federal compliance deadline plus the highest-volume state deadlines. State payroll tax, retail trading hours and licensing renewals have their own state cycles — see the state hubs (/states/nsw, /states/vic, etc.) for state-specific lists.
How do I subscribe via my calendar app?
Copy the link rulesmate.com.au/api/deadlines.ics and add it as a subscription in Outlook / Google Calendar / Apple Calendar. New and updated deadlines flow through automatically.
What time zone are deadlines in?
All deadlines are AEST/AEDT (Sydney time) unless explicitly noted. State deadlines follow that state's local time.
What if I'm exempt from one of these?
Most deadlines have entity-size or industry triggers (WGEA ≥100 emp, Modern Slavery ≥$100M, ASRS thresholds). Each obligation page on Rules Mate shows the exact triggers. The Fingerprint tool filters this for you.
