Super guarantee charge: what changes under Payday Super (and how to stay out of trouble)

Paying super (SG) late has never been a good idea, but under Payday Super the stakes will be even higher.

Right now, the super guarantee charge (SGC) generally turns up when employers miss the quarterly super deadlines. Once Payday Super begins (currently planned for 1 July 2026), the test shifts to each individual pay run. That means a few “small” delays here and there can add up quickly and attract SGC much sooner than many employers are used to.

This blog post walks through how the SGC works today, what is expected to change under Payday Super, and practical steps you can take now to stay out of SGC trouble.

Key takeaways

• Today, the SGC usually applies when you haven’t paid enough super to the right fund by the quarterly due dates, even if you catch up a little late.
• The current SGC is based on total salary and wages for the quarter, includes 10% p.a. interest from the start of the quarter plus a $20 per‑employee, per‑quarter admin fee, and is not tax‑deductible.
• Under Payday Super (planned from 1 July 2026), super will move to a per‑payrun model, using qualifying earnings (QE) as the base and expecting contributions to reach funds within about 7 business days of each payday (with a longer window for some first‑time contributions).
• The SGC framework is expected to be updated so that late or missed per‑payrun contributions can trigger SGC, not just quarterly shortfalls.
• The exact formulas under Payday Super are still being finalised as at March 2026, but policy material points to shortfall amounts, “notional earnings” and administrative uplifts/penalties, especially for repeated non‑compliance.
• You can reduce your SGC risk now by moving towards super each pay run, checking fund details and payroll settings, and tightening your STP and reconciliation processes.
• In Payday Super world, the onus is directly on the employer to ensure that super contributions reach super funds within the 7-day timeframe. This means that simply making the super payment on time does not exclude you from being liable for the SGC. The delays that could occur at the bank, clearing house and super fund end, could effectively cause super to be paid late, thus triggering a SGC liability. Again, ensuring successful payment of super within the 7-day period in terms of the SGC, falls squarely on the shoulders of employers, even though much of the process beyond making the payment is out of their control.

How the super guarantee charge works today

Under the current rules, the SGC is designed to compensate employees (and penalise employers) when the minimum super guarantee hasn’t been paid correctly or on time. You are liable for SGC if you:

• don’t pay the correct super for an eligible employee by the quarterly due date, or
• pay super late, to the wrong fund or with incorrect or incomplete information, so that the contribution is not properly received by the employee’s fund by the due date.

Quarterly SG due dates (current system)

Super contributions must be received by the fund by:

• Q1 (1 Jul–30 Sep): 28 October
• Q2 (1 Oct–31 Dec): 28 January
• Q3 (1 Jan–31 Mar): 28 April
• Q4 (1 Apr–30 Jun): 28 July

What makes up the current SGC

Today’s SGC has three main components:

• SG shortfall – the amount of SG that should have been paid but wasn’t, calculated on total salary and wages (including overtime) for the quarter, not just ordinary time earnings (OTE).
• Nominal interest – 10% per annum, calculated from the start of the quarter until the date the SGC is paid to the ATO.
• Administration fee – $20 per affected employee, per quarter.

On top of that, SGC is not tax‑deductible. Additional penalties can apply, including Part 7 penalties (up to 200% of the SGC), general interest charge (GIC) on unpaid SGC and penalties for failing employee‑choice obligations. If you miss a due date, you are expected to lodge an SGC statement and pay the SGC to the ATO, generally by one month after the SG due date for that quarter.

A quick refresher on Payday Super and qualifying earnings

Payday Super is planned to commence from 1 July 2026 and will apply to most employers with SG obligations, including small businesses.Instead of paying SG quarterly, employers will need to calculate and send contributions at or close to each payday, aligned to their pay cycle. Treasury and ATO material indicates that:

• super contributions will generally need to reach the employee’s super fund within about 7 business days of each payday, and
• there will be a longer window (around 20 business days) for the first contribution for a new employee or when an employee changes super funds, to allow for onboarding and data‑matching.

Under Payday Super, SG will be calculated on “qualifying earnings (QE)” at the legislated SG rate (expected to be 12% by 1 July 2026 – employers will need to check the current rate). Based on ATO and software‑developer guidance, QE is expected to be broadly similar to today’s ordinary time earnings (OTE) – for example:

• ordinary hours pay
• many loadings on ordinary hours
• many allowances
• commissions and bonuses linked to ordinary work
• paid leave.

As at March 2026, final QE schedules are still being settled, so the current OTE lists remain the best practical proxy when you’re reviewing your payroll.

SGC now vs under Payday Super – what is changing?

While the detail is still going through consultation, the direction of change is clear: the focus is moving from “Did you pay enough by the end of the quarter?” to “Did each pay’s super reach the fund on time?”

1. Trigger point for SGC

• Current rules (quarterly test): The ATO effectively looks at each quarter and asks: “By the quarterly due date, has the employee’s fund received at least the minimum SG on time?” If not, the whole shortfall for that quarter can fall into SGC, even if you pay the super shortly after the due date.
• Payday Super (expected per‑payrun test): The test is expected to move to each pay event: “Has the SG for this pay been paid, and has it reached the fund, within the allowed timeframe (about 7 or 20 business days)?” Late or missing contributions for a particular pay period can trigger SGC for that pay, without waiting for a quarterly review.

2. Calculation base

• Current rules: SGC is calculated on total salary and wages for the quarter, which is often broader than OTE (for example, including overtime).
• Payday Super (expected): Shortfalls are expected to be worked out based on unpaid SG on qualifying earnings (QE) for each pay period. Final legislation may adjust how this SGC base compares with today’s “salary and wages” base, so this is an area to watch as the law is finalised.

3. Interest/earnings and penalties

• Current rules: A single nominal interest rate of 10% p.a. applies from the first day of the quarter until SGC is paid, plus the flat $20 per employee, per quarter admin fee.
• Payday Super (expected direction): Policy material suggests the reformed SGC will still include the shortfall amounts, but may move towards:
  • “notional earnings” or daily interest that better reflects the investment earnings employees miss when contributions are late
  • an administrative uplift/penalty rather than a simple flat fee, especially for repeated or serious non‑compliance
  • possible additional loadings where employers also breach fund‑choice obligations.

4. Detection and enforcement

• Current rules: The ATO often finds out about unpaid super well after the fact – for example, via employee complaints, fund reporting or data‑matching. The ATO relies heavily on employers self-reporting late super payments via manually lodging a SGC statement.
• Payday Super: With STP reporting of qualifying earnings and super liabilities, plus more frequent contribution data, the ATO will have near real‑time visibility of who is falling behind. Employers can expect contact much sooner after a missed or late contribution. The ATO will raise and send a SGC liability notice to the employer after it receives notification that super payments were late or missed i.e. the ATO is in control of who will pay the SGC, not the employer.

5. Side‑by‑side snapshot

*Payday Super settings are based on Treasury and ATO guidance as at March 2026 and may change when final legislation and regulations are enacted.

How to avoid the SGC now and when Payday Super begins

1. Avoiding SGC under current rules (before 1 July 2026)

• Pay on time, every quarter. Make sure contributions are received by the fund by each quarterly due date, not just sent. Build in time for clearing‑house and bank processing.
• Use correct funds and member details. Confirm each employee’s super fund, USI, member number and choice form where applicable. Fix rejected or returned contributions promptly – a rejected payment that isn’t resent by the due date can still create SGC exposure.
• Check your SG calculations. Review which pay items you treat as OTE to ensure you’re paying at least the required SG % on all eligible earnings. Watch edge cases like allowances, bonuses, piece rates and leave payments.
• Self‑assess quickly if you’re late. If you do miss a due date, lodge an SGC statement and pay the SGC as soon as possible to limit interest and penalties. Voluntary, timely lodgement is generally viewed more favourably than waiting for ATO contact.

2. Preparing your payroll for Payday Super

• Shift towards “super every pay run”. Even before 1 July 2026, consider moving to per‑payrun super payments so the change is absorbed into your normal rhythm and cash flow.
• Map pay items to qualifying earnings (using OTE as a proxy). Use the ATO’s current OTE lists to review which earnings are likely to become QE. Correct any misclassified items now so your calculations are already robust when QE rules apply.
• Review software and clearing arrangements. Talk to your payroll software provider about how they will handle Payday Super (QE fields, per‑payrun SG, STP reporting and payment integration). If you rely on the Small Business Superannuation Clearing House, note that government material indicates it will be phased out from 1 July 2026, so you’ll need an alternative.
• Understand cut‑off times. Make sure your payroll calendar and super payment dates align with clearing‑house and fund processing windows so contributions reliably reach funds within the 7‑day (or 20‑day) windows.

3. Operating under Payday Super (from 1 July 2026 onwards)

• Lock in a repeatable process. Treat SG calculation and payment as a standard step in every pay run, not an end‑of‑quarter tidy‑up.
• Monitor fund receipts, not just payment files. Use clearing‑house or fund reports to confirm that contributions are successfully received within the required timeframe. Investigate and fix rejects, errors or delays straight away.
• Respond quickly to issues. If you find a shortfall or late payment, correct it promptly and consider voluntary disclosure before the ATO contacts you – this may reduce penalty loadings.
• Document your efforts. Keep clear procedures and evidence that you take reasonable care to meet your Payday Super obligations (checklists, payroll approvals, reconciliations). This can help if the ATO reviews your position.

When to seek advice

Because the Payday Super and updated SGC framework are still being finalised, it’s wise to:

• keep an eye on official ATO and Treasury updates, and
• speak with your bookkeeper, BAS agent or tax adviser if you’re unsure how the changes interact with your awards, enterprise agreements or industry practices.

Getting tailored advice now can help you tidy up any existing SG issues and design a Payday‑Super‑ready process that fits your business.

Stay updated

Payday Super represents a significant shift in how super is handled day to day. The aim is to protect employees’ retirement savings, but it also means employers will need stronger processes to avoid non‑deductible SGC bills.
