The ATO released its 2026 Tax Time toolkit for small business on 23 July. Most of the attention went to what is inside it — deduction guides, reporting summaries, a directory of calculators. Useful. But the change most likely to cost a small business money this year is not in the tax return at all. It is Payday Super, which commenced on 1 July, and which most employers are now two to four pay cycles into. That timing is the point. Four weeks in is roughly when the first rejected contributions come back.
What actually changed
Since 1 July, super is paid on every payday rather than quarterly. The detail that catches people is the deadline: the money has to be received by the employee’s fund within seven business days of payday. Not sent, not out of your account — received. A first contribution for a new employee gets a longer 20 business day window.
Two other changes travel with it. Super is now calculated on “qualifying earnings”, a broader base taking in ordinary time earnings, commissions and salary-sacrificed amounts. And Single Touch Payroll now reports both qualifying earnings and the matching super liability — which means the ATO can see the gap between what you owed and what landed, every payday, without having to ask you for anything.
Four checkpoints a year became fifty-two
Under the old system a business running weekly payroll had four super deadlines a year and a great deal of slack between them. If an employee’s fund details were wrong in the second week of a quarter, you would usually find out and fix it long before anything was late. The quarterly cycle quietly absorbed a lot of small errors.
That slack is gone. A weekly payroll now has up to 52 separate opportunities to trigger the super guarantee charge, and no buffer in which to self-correct.
The charge itself is worth understanding, because it is not a late fee you can settle and forget. Paying late reduces it but does not remove it: notional earnings accrue on the shortfall and compound daily, and an administrative uplift of 60% applies to the shortfall and those earnings combined. Voluntary disclosure within 30 days of the qualifying earnings day reduces the uplift (Hall & Wilcox, Clayton Utz).
The failures are record-keeping failures
It is worth being precise about what actually goes wrong here, because it is rarely the payment. In the guidance published ahead of the changeover, the recurring causes are the same short list:
- Fund details that are out of date — wrong USI or member number
- Member mismatches, where the name, date of birth or TFN in your payroll does not match the fund’s record
- Incomplete employee records
- Contractors who should be treated as employees for super, or the reverse
- Pay codes mapped to the wrong earnings base, which matters more now that the base has widened
None of those are accounting problems. They are data problems, and many of them have been sitting in small business payroll systems for years without consequence, because a quarterly cycle was forgiving enough to hide them. A seven business day cycle is not.
That is the part I would take seriously. The reform did not create these errors. It removed the slack that was concealing them.
What the ATO says it will do about it
Some reassurance, and it comes from the ATO rather than from me. For the first year — to 30 June 2027 — the ATO has said it will take a facilitative approach. Employers who are genuinely paying on payday but occasionally slip because of a rejected contribution or incorrect details, and who fix it promptly, are expected to be treated as low risk and not to be the focus of compliance action.
That is not a grace period for not paying. It is a year of tolerance for getting the mechanics wrong while you sort the records out — a meaningfully different thing, and a good argument for using the next few months rather than waiting to see what happens.
What to check this month
- Reconcile employee records against fund records before a pay run, not after a rejection. A one-off comparison of name, date of birth, TFN, USI and member number across your payroll export and your fund confirmations will find most of what is going to bite you.
- Decide who owns a rejected contribution. Under a quarterly cycle this could sit in someone’s inbox for a fortnight. It cannot now. The exception needs a name against it and an alert that reaches that person.
- Check your pay codes against qualifying earnings — commissions and salary sacrifice in particular, since the base has broadened.
- Confirm your clearing house. The Small Business Super Clearing House cannot be used for payments from 1 July 2026. If you were relying on it, download your records and move.
- Look hard at cash flow. The final quarterly payment for the June quarter fell due on 28 July, on top of the payday contributions you have been making since 1 July. Two obligations landed in the same month.
None of this needs new software or a project. What it needs is for the employee data you already hold to be correct, and for someone to notice quickly when it is not. The businesses that find Payday Super painful will mostly be the ones whose payroll records were already wrong and never had cause to find out.
That is a data quality problem with a deadline attached — and it is a good deal cheaper to fix deliberately in August than to discover 52 times over the coming year. If you want a second set of eyes on what your payroll and finance data is actually telling you, that is what a data health check is for.
