Why dates matter more than you think
For most business owners, deadlines never arrive in isolation.
Business Activity Statements (BAS) roll into super. Super overlaps with payroll. Payroll collides with public holidays, school holidays and staff leave. Add tax lodgements and ASIC fees and cashflow pressure builds quietly in the background.
For healthcare practices, professional services firms and small to medium enterprises, poor timing is not just inconvenient. It can mean:
- cash tied up at the wrong moment
- missed deductions or late payments
- compliance penalties that were entirely avoidable
In 2026, the stakes rise again. Payday super, commencing on 1 July, removes the buffer many employers have relied on for decades. Super is no longer a quarterly consideration. It becomes a real-time cashflow obligation.
That makes forward planning non-negotiable.
Below is a practical, month-by-month guide to the key business, financial and public dates Australian business owners should be planning around in 2026.
2026 key business dates by month
January
- 1 January: New Year’s Day (national public holiday)
- 26 January: Australia Day (national public holiday)
- 28 January:
- Super guarantee due for the October–December 2025 quarter
Key tip: January is often quieter operationally, making it an ideal time to clean up bookkeeping, review payroll systems and stress-test cashflow for the year ahead.
February
- 28 February:
- December quarter BAS due
- Payment summary final checks, where applicable
- Company ASIC annual review fees often fall due around this time, depending on registration date
Key tip: February is a common pinch point for businesses that treated January as downtime rather than planning time.
March
- 31 March: Fringe benefits tax (FBT) year ends
Key tip: March is the preparation window for FBT returns and valuations. Even businesses that do not usually lodge FBT should confirm whether vehicles, entertainment or other benefits trigger obligations.
April
- 3 April: Good Friday (national public holiday)
- 6 April: Easter Monday (national public holiday)
- 28 April: March quarter BAS due
Key tip: Multiple public holidays in April can disrupt billing cycles and staff availability, particularly in healthcare and service-based businesses.
May
- 21 May: FBT return due, if applicable
- PAYG instalment reviews recommended
Key tip: May is one of the most effective months for strategic tax planning, well before end-of-financial-year pressure sets in.
June
- 8 June: King’s Birthday (observed in most states) – Note: State and territory public holidays can also trip you up if you haven’t planned ahead. Check out our calendar of 2026 public holidays to support your annual planning.

- 30 June: End of financial year
Key tip: Key end-of-year actions include finalising deductions, asset purchases, trust distributions and super contribution strategies.
July
- 1 July:
- Payday super rules commence
- New financial year begins
- 28 July:
- June quarter BAS due
- Super guarantee due for the April–June quarter
Key tip: From this point forward, super must be paid at the same time as wages. Businesses without sufficient payroll buffers will feel this change immediately.

August
- Ongoing payroll compliance checks under payday super
Key tip: August is often when weaknesses in payroll systems and processes become visible.
September
- 30 September: Super guarantee reconciliation deadline for corrections or adjustments
Key tip: Early tax planning for individuals and trusts is strongly recommended during September.
October
- 28 October: September quarter BAS due
- 31 October:
- Individual tax returns due if self-lodged
- Trust distribution resolutions must be finalised
Key tip: October is one of the heaviest compliance months of the year.
November
November is typically lighter on statutory deadlines and is well suited to:
- Budget resets
- Staffing and leave planning
- Reviewing profitability before year-end shutdowns
Key tip: Well-run businesses use November for reflection, not recovery.
December
- 25 December: Christmas Day (national public holiday)
- 26 December: Boxing Day
- 28 December: Boxing Day observed (national public holiday)
Key tip: Reduced trading days and staff availability make December a critical month for cashflow planning. Preparation for December quarter BAS and January super obligations often determines how calm, or chaotic, the new year becomes.
The strategic takeaway
Compliance dates are not just reminders. They are decision points.
Businesses that map these dates early can smooth cashflow, manage staffing intelligently and avoid reactive decision-making. Those that do not often end up funding tax and super obligations under pressure.
With payday super commencing in July 2026, the margin for error narrows significantly.
The most resilient businesses treat their calendar like a financial tool, not an afterthought.
Plan early. Review often. And make your 2026 calendar work for your business, not against it.
