SCHADS Underpayment Risk Calculator
By CrossVault · Updated
Most SCHADS underpayment isn't a payroll officer mistyping a rate — it's four systematic patterns repeating quietly every pay run: missed broken shift allowances, unpaid sleepover disturbances, short shifts paid below the minimum payment, and workers sitting a pay point behind their anniversary. This calculator prices those patterns for your workforce at the 1 July 2026 award rates. Every assumption is adjustable, and the formulas are shown in full below.

How the Estimate Is Calculated
- Missed broken shift allowances = annual shifts × % broken days × % missing the allowance × $21.81 (clause 25.6 / 20.12(a); the 2-break allowance of $28.87 would increase this).
- Unpaid sleepover disturbances = sleepover nights per year × % with an unpaid disturbance × your hourly rate × 150% — the clause 25.7(e) minimum of 1 hour at overtime rates, counting a single disturbance per affected night. Multiple disturbances each attract their own hour, so this is conservative.
- Minimum payment shortfalls = annual shifts × % under-paid × 1 hour at the ordinary rate — a conservative average gap for short engagements paid as worked instead of at the clause 10.5 minimum (2 or 3 hours by stream).
- Pay point lag = workers behind × $1.14/hour (the SACS Level 2.1 → 2.2 step at 1 July 2026 rates) × 38 hours × 52 weeks — ordinary hours only; penalties and overtime on the same gap would add 20–40%.
Why These Four Patterns
From Estimate to Evidence
Common Questions
Frequently Asked Questions
- How accurate is this underpayment estimate?
- It's a transparent model, not an audit: your workforce inputs multiplied by adjustable error-rate assumptions, priced at the 1 July 2026 award figures. The default assumptions reflect patterns commonly seen in provider timesheets, and the model deliberately omits several error types, so real audited exposure is often higher. For an evidence-based number, audit actual timesheets.
- Why does the calculator multiply the annual figure by six?
- Underpayment claims under the Fair Work Act can reach back up to 6 years, and systematic payroll errors typically run unchanged until found. If a misconfiguration has existed for the full period, the accumulated exposure approaches six times the annual figure — before interest, penalties or the super owed on the qualifying part of the back pay.
- What are the biggest sources of SCHADS underpayment?
- In our timesheet audits: missed broken shift allowances, minimum payments not applied to short engagements, unpaid sleepover disturbances, whole-shift loadings paid partially, wrong overtime bands by stream, and classification or pay point errors. The calculator prices the four most quantifiable; the others add to real exposure.
- Does underpayment also create a superannuation problem?
- It adds a super bill, but an underpayment is not a late-super problem by itself. Unpaid wages owe no super until they are paid. Once back pay is paid, super at 12% is owed on its qualifying-earnings part (ordinary hours, casual loading and penalties) and is due 7 business days after the payday it goes out on, or by the next regular payday's deadline if it is paid separately from the regular pay cycle. Overtime-rate components, such as a sleepover disturbance paid at overtime rates, are not qualifying earnings. The superannuation guarantee charge, which adds notional earnings and an administrative uplift, applies only if that super is then paid late, or if earnings that were paid were wrongly treated as not attracting super. The ATO has not ruled on the SCHADS broken shift and sleepover allowances, so confirm how they are treated with the ATO or an adviser.
