EOFY 2026 Checklist: Every Deadline Australian Small Businesses Need Before 30 June
The 2025–26 financial year ends on 30 June 2026. This year has more moving parts than usual, with several major changes landing the very next day.
Here is a simple checklist to get your business ready, along with the key dates you cannot afford to miss.
Before 30 June: Clean Up Your Books
Start with reconciliation. Match your bank accounts, GST coding, invoices, and expenses before the year closes.
Chase any overdue invoices now. Outstanding debtors are far easier to collect before EOFY than after.
If your business holds stock, complete a stock take. This figure directly affects your taxable income for the year.
Before 30 June: Use the Instant Asset Write-Off
Eligible small businesses can immediately deduct assets costing less than $20,000, instead of depreciating them over several years.
To qualify for this financial year, the asset must be first used or installed ready for use by 30 June 2026. Assets purchased after that date cannot claim this benefit for 2025–26.
A separate proposal would make this write-off permanent from 1 July 2026 onward, but that change is not yet law. The current $20,000 threshold for this financial year is confirmed.
Key Dates After 30 June
14 July 2026 — Single Touch Payroll finalization deadline. Employee income statements must be ready for tax time.
28 July 2026 — Final quarterly super guarantee payment, covering April to June. This is the last quarterly super payment most businesses will ever make, since Payday Super begins the day before.
31 October 2026 — Tax return deadline for self-lodgers. A registered tax agent may give you extended time.
The Big Change Starting 1 July
From 1 July 2026, Payday Super replaces the quarterly system. Super must be paid with every pay run, landing in your employee’s fund within seven business days.
This is the moment to confirm your payroll software is ready, and that you have moved off the ATO’s Small Business Superannuation Clearing House before it closes.
The tax rate on income between $18,201 and $45,000 also drops from 16 percent to 15 percent from this date, automatically through payroll.
A Simple EOFY Checklist
Reconcile all accounts and GST coding before 30 June.
Finalize any equipment purchases if you plan to use the instant asset write-off this year.
Pay your final quarterly super by 28 July and confirm it has cleared in time.
Confirm your payroll software and clearing house are ready for Payday Super from 1 July.
Finalise Single Touch Payroll by 14 July and prepare for the new tax year ahead.
Frequently Asked Questions
What is the most important EOFY deadline this year? The 28 July super guarantee payment matters most, since it is the final quarterly payment before Payday Super takes over.
Is the instant asset write-off definitely $20,000 this year? Yes, for assets installed by 30 June 2026. A proposal to make this permanent beyond that date is still not law.
Do I need to do anything differently because of Payday Super? Yes. Your payroll system and super clearing house need to be ready before your first pay run in the new financial year.
