Super Guarantee 2026: the 12% Rate, Due Dates & Penalties

Let me start with the basics, then I'll explain why this matters so much.

What is the Super Guarantee?

The Super Guarantee is an Australian employer obligation. If you have employees, you must contribute a percentage of their salary to their chosen superannuation fund. The current rate is 12% of their ordinary time earnings — the legislated step-ups finished when the rate reached 12% on 1 July 2025.

It's not voluntary — it's a legal minimum. Every eligible employee (generally anyone earning over a threshold, currently around $11,700 per year) must receive Super Guarantee contributions. There are very few exceptions.

The key thing: Super Guarantee isn't optional for employees, and it's not a salary sacrifice arrangement. It's a legal obligation on you, the employer. You have to pay it, regardless of whether the employee asks for it or how their pay is structured.

When is Super Guarantee due?

This is where a lot of business owners get tripped up. Super Guarantee is due within 28 days after the end of each quarter. The quarters are:

• Q1 (1 July – 30 September): Due 28 October
• Q2 (1 October – 31 December): Due 28 January
• Q3 (1 January – 31 March): Due 28 April
• Q4 (1 April – 30 June): Due 28 July

The ATO is strict about these dates. There's no grace period. If the payment isn't in the super fund by that date, you've missed the deadline — even if it's sitting in your bank account ready to transfer.

What happens if you miss the Super Guarantee deadline?

Here's the part that hurts. If your super payment is late, the ATO charges you a Super Guarantee Charge (SGC). And this is where it gets expensive.

The SGC is more than the super contribution itself. It typically includes:

• The super contribution amount you should have paid
• Interest on that amount (at the current ATO interest rate)
• An additional penalty component (which varies but is substantial)

In practical terms: if you owed $10,000 in super and it was 6 months late, the SGC might be $12,500 or more. You're paying interest and penalties on top of the original obligation.

And here's the kicker: the SGC is not tax deductible. You have to pay it from after-tax profit. Compare that to the original super contribution, which IS tax deductible. So missing the deadline costs you significantly more than paying on time.

What else happens if you're late?

Beyond the financial penalty, there are other consequences:

• ATO notice: The ATO will contact you. Ignoring their correspondence always makes things worse, so respond immediately.
• You must lodge a Super Guarantee Charge Statement: This is a formal lodgement with the ATO acknowledging the late payment. It becomes part of your compliance record.
• Director liability: If you're a company director, you can personally be held liable for unpaid super in certain circumstances — which is why this matters to you personally, not just the business.
• Employee issues: Your employees have a right to their super. If you've withheld or delayed it, they have a legal claim against you. This can lead to disputes, reputational damage, and in serious cases, court action.

How to make sure you never miss a Super Guarantee payment

It's honestly not complicated if you have a system:

1. Know your calculation. Super is calculated on ordinary time earnings — generally, wages and salaries, but not bonuses, redundancy, or some other payments. Your payroll software should calculate this automatically.

2. Set calendar reminders early. Don't rely on memory. Set a reminder for the 15th of each deadline month (October, January, April, July). That gives you two weeks to process and send the payment.

3. Use regular, ongoing contribution payments. The best way to ensure you're never late is to pay super regularly — monthly or fortnightly, along with your payroll. This removes the "bulk payment at quarter-end" crunch and spreads the cash flow impact.

4. Use your payroll software or ATO's SuperStream portal. Electronic payments to super funds are straightforward and can be set up as recurring. No manual cheques, no processing delays.

5. Work with a bookkeeper who tracks this. This is honestly one of the best investments. A bookkeeper tracks super accruals, reminds you of deadlines, and ensures payments are made on time. It's a small cost compared to an SGC penalty.

The bottom line

Super Guarantee isn't optional, and the due dates aren't flexible. But with a simple system — calendar reminders, regular payments, and solid bookkeeping support — you'll never miss a deadline.

And your employees will get their super on time, which is what they're legally entitled to. That builds trust with your team and keeps you out of trouble with the ATO.
