Super
Payday Super for Casual & Part-Time Staff (From 1 July 2026): Irregular Hours, Sorted
From 1 July 2026, super on casual and part-time wages must be received by each fund within 7 business days of every payday — there is no carve-out for irregular hours. Here is exactly how per-payday super works when your roster never looks the same two weeks running, and what to do before the SBSCH closes on 30 June 2026.
If you employ casuals or part-timers, your super has always been the lumpy part of payroll. One fortnight a casual picks up four shifts; the next, none. Under the old quarterly system that lumpiness washed out — you tallied a quarter's worth of earnings and paid super once. From 1 July 2026 that ends. Payday super means the 12% you owe has to be received by each worker's fund within 7 business days of every single payday, however irregular the hours behind it.
This guide is for the small employer or bookkeeper running a casual-heavy or mixed roster. It walks through how the new clock treats irregular pay, which casual pay items super is actually due on, the traps that catch variable rosters, and the short list of things to fix before the cutover.

The one rule that changes everything
Payday super does not change how much super you owe a casual. It changes when it has to land. The facts, confirmed against the ATO:
- The rate is 12% for FY2026-27 — the superannuation guarantee rate is unchanged and not rising further.
- Super is worked out on the qualifying earnings (QE) paid on each payday, not pooled across a quarter. QE is essentially ordinary time earnings (OTE) plus certain other payments. What counts as OTE has not changed.
- The 7-business-day rule: super is on time only when it is received by the fund — with everything the fund needs to allocate it to the member — within 7 business days of the qualifying-earnings payday. Received-by, not sent-by. Business days, never calendar days.
- No casual, part-time, or small-business exemption. Every employer is in, regardless of size or workforce mix.
For the full background on the change, see the complete employer guide to payday super and the deeper explainer on why "received within 7 business days" is the rule that matters. The headline for anyone with casuals: every payday now stands on its own.
Does payday super apply to casuals? (Short answer: yes)
There is a stubborn myth that casuals are somehow "out" of super, or that very short shifts do not count. Neither is true under the new rules.
Casual employees are covered exactly the same way as everyone else. If a casual is paid qualifying earnings on a payday, the 12% super on those earnings is due — and from 1 July 2026 it is due on that payday, received by the fund inside 7 business days. The old $450-per-month earnings threshold has already been removed, so super is generally payable on qualifying earnings from the first dollar, no matter how few hours a casual worked. A handful of narrow exceptions still exist (for example, some employees under 18 who work 30 hours or less in a week), but for the typical adult casual, super is due on every dollar of qualifying earnings.
So the question is never "is this casual big enough to bother?" It is "what were their qualifying earnings this payday, and is the 12% on track to be received within 7 business days?"
Which casual pay items attract super
Because the reform does not change what is OTE, the rules you already follow still decide what super is due on — you are simply paying it sooner. Here is how the common casual and part-time pay items sit:
| Pay item | Part of qualifying earnings? | Super due on payday? |
|---|---|---|
| Ordinary hours (casual or part-time) | Yes — it's OTE | Yes |
| Casual loading on ordinary hours | Yes — OTE | Yes |
| Penalty rates for ordinary hours (weekend, evening) | Yes — OTE | Yes |
| Public-holiday loading on ordinary hours | Yes — OTE | Yes |
| Shift allowances that are OTE | Yes — OTE | Yes |
| Overtime (where ordinary hours are clearly identified) | No — not OTE | No |
| Reimbursements (e.g. genuine expense repayments) | No — not OTE | No |
| Salary-sacrificed amounts that would have been QE | Yes — included | Yes |
The item that trips up casual payroll most is casual loading. The 25% (or award-specified) loading a casual gets on their ordinary hours is part of OTE, so super is due on it. Don't strip it out. By contrast, overtime is not qualifying earnings — provided your award or agreement clearly identifies ordinary hours — so you don't accrue super on it. If you are unsure whether a particular hour is "ordinary" or "overtime" for a casual under your award, that is a question to confirm with the Fair Work Ombudsman or a BAS agent, because it decides whether super applies.
How the 7-day clock treats irregular hours
This is the part that feels new. With quarterly super you had one big calculation every three months and the week-to-week variation didn't matter. Under payday super, each pay run triggers its own contribution and its own 7-business-day deadline.
Concretely, for a casual whose hours swing around:
- Every payday is calculated on what was actually paid in that run. A quiet week with one shift produces a small super amount; a busy week with five produces a larger one. You apply 12% to that payday's qualifying earnings — no averaging, no smoothing.
- Each payday starts its own clock. The 7 business days run from that payday. There is no "I'll catch it up next time" — a missed run is a late contribution on its own terms, even if the next run is on time.
- A zero-hours fortnight is simply zero super. If a casual is rostered nothing and paid nothing, there are no qualifying earnings and nothing is due for that payday. You don't owe a placeholder contribution.
So the operational shift is from one quarterly batch to a small, reliable habit every single pay run. The annual super bill for a casual is identical to before — same 12% on the same qualifying earnings across the year. What changes is the rhythm and the working-capital timing: the money leaves with each run instead of sitting in your account until quarter-end. To see what that does to your cash, run your own numbers in the free Payday Super cashflow calculator — it shows super-per-payday and the annualised figure for a variable roster, with a live countdown to 1 July 2026.

The new-starter trap (and the 20-day window that helps)
Casual rosters churn people. That means a steady stream of first contributions to new funds — and first contributions are where late and bounced super most often happens, because the fund details aren't confirmed yet.
The ATO gives you some room here. For the first contribution to a new employee, or the first contribution to a new fund, the deadline is 20 business days after the qualifying-earnings day, not the usual 7. Use that window deliberately:
- Get the fund and member details right the first time. A new casual's TFN, fund USI/ABN and member number need to be correct before that first contribution goes out, or it bounces and the clock keeps running.
- Chase stapled-fund details promptly. If a new casual doesn't nominate a fund, you generally request their stapled fund from the ATO — do it early so the first contribution can be made and confirmed.
- Remember the second contribution is back to 7 days. The 20-day window only applies to the first contribution. Once a casual is set up, every later payday runs on the standard 7-business-day deadline.
What late super actually costs (and the two penalties people confuse)
The point of getting the rhythm right is avoiding the superannuation guarantee charge (SGC). If a casual's super isn't received by the fund in time, you can become liable for it. Two separate penalties sit inside the redesigned system, and they are routinely conflated — they are not the same thing:
- The late-payment penalty (25%, or 50%) is not remittable. Under the new-look SGC from 1 July 2026, a late-payment penalty of 25% of the super shortfall applies — rising to 50% if you were liable for the SGC at any time in the prior 24 months. The Commissioner cannot reduce or remit this component. It is the cost of being late, full stop.
- The separate Part 7 penalty (up to 200%) is remittable. On top of the charge, a distinct Part 7 penalty of up to 200% of the SGC can be imposed. Unlike the late-payment penalty, this Part 7 penalty can be remitted (reduced) by the ATO in appropriate cases — for example where you've engaged early and cooperated.
The practical takeaway for a casual-heavy payroll: the non-remittable 25%/50% bites on every shortfall, so the cheapest strategy is simply never to be late. There is no guaranteed escape and no "she'll be right" once a deadline passes. For the full breakdown, see the new SGC and penalties explainer.

What to do before 1 July 2026
A short, casual-roster-specific checklist:
- Confirm your payroll software is payday-super-ready and reports year-to-date qualifying earnings and YTD super per employee each payday via Single Touch Payroll — including for irregular casual runs.
- Check your clearing-house or fund turnaround beats 7 business days. A slow clearing house is now a compliance risk on every pay run, not just an annoyance once a quarter.
- Map every casual pay item (loading, penalty rates, allowances, overtime) to "QE or not" so super calculates correctly on every variable run.
- Clean up fund details for current casuals now — stale or missing fund data is the single biggest cause of late and bounced contributions on a churning roster.
- Move off the SBSCH. The Small Business Superannuation Clearing House closes 11:59pm AEST 30 June 2026; see the SBSCH closing guide for alternatives and how to migrate.
- Do a dummy run before 1 July with a couple of casuals to confirm super is received inside 7 business days end to end.
Work through the full 12-point readiness check to confirm nothing's been missed, and run the cashflow calculator on your variable roster so 1 July holds no surprises. If you want the policy, the per-payday SOP and the casual employee comms already written for you, the Payday Super Compliance Pack (A$79) has the editable templates.
