Super Contribution Deadline 2027: Australia Dates & Compliance
September 19, 2026 | By Gopareto Marketing
If you’re an Australian employer, you’re required to contribute to employees’ superannuation. Miss the deadline and you face penalties of up to 200% of the unpaid contribution amount. That’s not a warning—that’s a fine that will hurt.
But superannuation deadlines aren’t straightforward. There are quarterly deadlines, annual deadlines, and special rules for different employee types. Many employers get confused and miss them.
This guide lists every superannuation contribution deadline for 2027, explains what triggers penalties, and shows how to automate compliance so you never miss one again.
Superannuation Basics
Superannuation is mandatory retirement savings for Australian employees. As an employer you must contribute a minimum percentage of ordinary time earnings—11.5% as of 2027, rising annually—to the employee’s nominated fund, by a specified quarterly or annual deadline.
Super is required when an employee
- Is 18 years or older
- Earns A$11,200 or more per year
- Is not a contract worker, unless super inclusion was agreed
Exceptions where no super is due
- Casual employees earning under A$11,200 a year
- Contract workers, unless agreed otherwise
- Non-residents, under specific rules
- Contractors and ABN holders
Super Contribution Deadlines 2027
Quarterly Deadlines
Most employers contribute quarterly. The rule to remember: the 28th of the month following the quarter.
| Quarter | Period | Contribution deadline |
|---|---|---|
| Q1 | 1 Jul – 30 Sep 2026 | 28 October 2026 |
| Q2 | 1 Oct – 31 Dec 2026 | 28 January 2027 |
| Q3 | 1 Jan – 31 Mar 2027 | 28 April 2027 |
| Q4 | 1 Apr – 30 Jun 2027 | 28 July 2027 |
The Full 2027 Calendar
| Submission period | Contribution due |
|---|---|
| 1 Jan – 31 Mar 2027 | 28 April 2027 |
| 1 Apr – 30 Jun 2027 | 28 July 2027 |
| 1 Jul – 30 Sep 2027 | 28 October 2027 |
| 1 Oct – 31 Dec 2027 | 28 January 2028 |
Annual Contribution Alternative
Some smaller employers contribute annually instead. For financial year 2026–27, running 1 July 2026 to 30 June 2027, the contribution is due by 28 October 2027—28 days after the financial year ends.
What Triggers Penalties
Late contribution
- An interest charge applies from day one late
- The rate adjusts quarterly, typically 5–7% a year
- A$100,000 due on 28 April and paid on 28 May costs roughly A$416–583 in interest
Under-contribution
- You owe the shortfall plus interest plus a penalty
- The penalty can reach 50–100% of the unpaid amount
The Superannuation Guarantee Charge
If you fail to contribute at all, the ATO issues a Superannuation Guarantee Charge: the unpaid contribution, plus interest of 10% or more per year, plus the SGC itself at 10% and an administration fee. In total that reaches 100–200% of the unpaid amount.
| Worked example: A$1,000,000 owed, paid 12 months late | Amount |
|---|---|
| Unpaid contribution | A$1,000,000 |
| Interest at 10% per annum | A$100,000 |
| SGC penalty at 10% plus admin | A$105,000 |
| Total cost | A$1,205,000 |
Director Penalty Notices
- In cases of deliberate non-compliance, the ATO can make directors personally liable for unpaid super
- Personal assets, bank accounts and property can be pursued
- This applies where a company deliberately withholds super, the director is aware, and payment doesn’t follow notices
Your 2027 Quarterly Compliance Checklist
The same process runs each quarter. Complete it before the quarter closes, and lodge by the 28th of the following month.
Calculate
- Calculate 11.5% of each employee’s ordinary time earnings
- Identify new employees who crossed the A$11,200 threshold
- Identify employees who left, and finalise super by their departure date
Verify and lodge
- Confirm fund name, ABN and account number for each employee
- Check default fund assignment for new employees
- Generate the super contribution file
- Submit to the ATO via SuperStream electronic lodgement
- Process payments to the super funds
Year-end, by 30 June 2027
- Finalise all super contributions for the year
- Reconcile against payroll
- Prepare the superannuation year-end statement
- Review any disputes or corrections needed
Five Mistakes That Cost Employers Money
Wrong contribution percentage
Calculating 10% instead of 11.5%. The rate rises each year: 11.5% in 2026–27, an estimated 12% in 2027–28. Check whether your payroll system reflects the current rate.
Missing threshold crossings
Once a casual employee earns A$11,200 in a financial year, super starts. Run a quarterly payroll audit to catch newly eligible staff.
Contributing to the wrong fund
Employees choose their fund, and contributions must go there unless they have none. Keep a current employee super fund register.
Late final payments on departure
Super is payable as at the employee’s last day of engagement. Flag departures so final super is processed immediately, not at the next monthly run.
Ignoring SuperStream
The ATO requires electronic SuperStream submissions in XML format. A manual bank transfer doesn’t count as compliant lodgement.
Why Automation Pays for Itself
Managing super manually is error-prone, and one mistake costs thousands in penalties.
The manual process
- Spreadsheet-based calculations
- Manual percentage updates that are easy to miss
- Email coordination with super funds
- No audit trail when disputes arise
- High penalty risk
The automated process
- Payroll calculates super, and updates the rate when it changes
- Employees crossing the threshold are identified automatically
- SuperStream files are generated for you
- Deadline reminders arrive before the 28th
- Payment confirmations and a full audit trail are retained

Conclusion
Super contribution deadlines in Australia are quarterly—28 October, 28 January, 28 April and 28 July—or annual, on 28 October. Missing them costs 100–200% in penalties, which is never worth the risk.
Automate your super compliance and you’ll ensure no deadline is missed, no calculation is wrong, and no penalties are incurred.
