Under 18 and working more than 30 hours: when super starts in 2026

Published by SESAY · 2026-11-03 · General Australian payroll guidance

What to understand first

Australian super guarantee rules treat age and weekly hours differently from junior wage rates. Current Fair Work guidance says an employee under 18 is eligible for super guarantee when they work more than 30 hours in a week; exactly 30 hours does not meet that test. From 1 July 2026, eligible contributions are generally calculated at 12% of qualifying earnings and paid on payday, with receipt by the fund generally required within seven business days unless an extended timeframe applies. The ATO's employer guidance explains that actual hours are tested week by week and cannot be averaged across a fortnightly or monthly pay period. Once an employee is 18, the under-18 hours test no longer applies. Award coverage, junior pay rates and lawful working-hour restrictions are separate questions.

Practical checks

• Record the employee's verified date of birth and actual hours by week. Do not use the fortnightly total or an average of two weeks to decide whether the more-than-30-hours test is met.
• Identify each week in which the employee worked more than 30 hours. Treat a week of exactly 30 hours separately because the current test says more than 30.
• Map the qualifying earnings attributable to each eligible week and calculate the contribution using the current rate. Do not assume every allowance or payment is qualifying earnings.
• Include the contribution in the relevant payday process and reconcile the amount from payroll calculation through submission to fund receipt. Apply any extended receipt timeframe only when the official exception fits the facts.
• Investigate missing super by checking age, weekly hours, earnings mapping, fund details and provider outcomes. A zero contribution should have an explainable reason rather than an unexplained system flag.
• Update the eligibility control when the employee turns 18 and retain enough time-and-wage evidence to explain the calculation.

Fictional example

Fictional employee Maya is 17 and paid fortnightly. Assume she earns $24 per hour, all ordinary wages in this example are qualifying earnings and no extended contribution timeframe applies. Maya works 28 hours in week 1, earning 28 × $24 = $672, and 34 hours in week 2, earning 34 × $24 = $816. Week 1 does not pass the more-than-30-hours test. Week 2 does, so the assumed super contribution is $816 × 12% = $97.92. Averaging the fortnight to 31 hours per week would incorrectly treat both weeks alike. Payroll should also confirm the fund receives the $97.92 within the applicable timeframe.

Your next step

Check the last three pay cycles for employees under 18. Compare the weekly time record with the payroll eligibility result, then trace any calculated contribution to fund receipt. Ask payroll to document how split weeks, late timesheets and corrections are handled. Employees should compare their roster, payslip and fund transactions, but allow for processing timing before concluding that super is missing. Raise unexplained differences with the employer and use current ATO or Fair Work guidance rather than relying on a coworker's arrangement.

How SESAY can help

SESAY can help employers and payroll teams design a weekly-hours exception report, test age-based eligibility settings, document the Payday Super handoff and reconcile contribution outcomes within an agreed scope. SESAY does not determine individual legal entitlements, replace the employer's records or guarantee that a software configuration is compliant without evidence and review.
