Can my employer use super salary sacrifice to pay me less than the minimum wage?

No. Salary sacrifice agreements reduce your gross salary in exchange for additional super contributions, but your ordinary time earnings (the amount before any sacrifice) must still meet the applicable minimum wage or award rate. The Fair Work Ombudsman treats salary sacrifice as a post‑agreement arrangement; it cannot bring your base pay below the legal floor.

Does super salary sacrifice affect my casual loading or penalty rates?

Yes, if your award or agreement defines ordinary time earnings as the rate before salary sacrifice. Casual loadings and penalty rates are usually calculated on the base hourly rate, not the sacrificed amount. Check your award or enterprise agreement; the Fair Work Ombudsman’s guides explain how loadings interact with salary sacrifice.

Is the super guarantee still payable on salary‑sacrificed amounts?

Yes. The super guarantee (12% from 1 July 2026) is calculated on your ordinary time earnings, which include the amount you salary sacrifice. Your employer must contribute 12% of your pre‑sacrifice earnings into your super fund. Salary sacrifice does not reduce the employer’s super obligation.

Super Salary Sacrifice and the Minimum Wage: How It Affects Your Pay Floor

The adult national minimum wage from 1 July 2026 is $26.44 per hour or $1,004.90 per week, with super guarantee of 12% on top; salary sacrifice arrangements cannot reduce your ordinary time earnings below this floor.

Super Salary Sacrifice and the Minimum Wage

When you arrange a super salary sacrifice with your employer, you agree to forgo part of your before‑tax salary in exchange for additional contributions to your superannuation account. This can reduce your taxable income, but it also raises questions about how the arrangement interacts with Australia’s minimum wage and award system. This guide explains the legal floor that applies and how salary sacrifice fits within the rules set by the Fair Work Commission and enforced by the Fair Work Ombudsman.

The Legal Minimum Wage Floor

From 1 July 2026, the national minimum wage for adult award‑free employees is $26.44 per hour or $1,004.90 per week for a 38‑hour ordinary week. Casual employees receive a 25% loading, bringing the casual minimum to $33.05 per hour. These rates are set by the Fair Work Commission and apply to national‑system employees who are not covered by a modern award or enterprise agreement.

Superannuation is an additional payment on top of the minimum wage. The super guarantee requires employers to contribute 12% of ordinary time earnings (OTE) into the employee’s super fund. OTE is the gross salary before any salary sacrifice arrangement. Therefore, even if you salary sacrifice part of your pay into super, your employer must still pay the full minimum wage rate as your base earnings, and then contribute 12% super on that base amount.

Award Coverage vs Award‑Free Rates

Most private‑sector employees are covered by a modern award. Awards set minimum wages for specific industries and occupations, and these rates are generally higher than the national minimum. From the first full pay period on or after 1 July 2026, award minimum wages rise by 4.75%, but the lowest ongoing classification cannot fall below the national minimum of $26.44 per hour. Introductory rates (for the first six months in a job) are capped at $25.74 per hour or $978.10 per week.

If you are award‑free (no award or enterprise agreement applies), the national minimum wage is your floor. However, junior employees, apprentices, and trainees may be paid less. For award‑free juniors, the percentages range from 36.8% for under‑16s ($9.73 per hour) to 97.7% for 20‑year‑olds ($25.84 per hour). These rates are before super and before any salary sacrifice.

How Salary Sacrifice Interacts with the Minimum

Salary sacrifice is a voluntary agreement between you and your employer. It cannot reduce your ordinary time earnings below the applicable minimum wage or award rate. For example, if your award rate is $28.00 per hour, you cannot sacrifice so much that your base pay drops to $26.44. The sacrifice is deducted from your gross pay after the minimum is satisfied.

Employers sometimes offer salary sacrifice for super as a tax‑effective benefit. The Australian Tax Office (ATO) allows this, but the arrangement must be documented and cannot breach the National Employment Standards or the Fair Work Act. The Fair Work Ombudsman provides guidance on salary sacrifice and minimum entitlements.

Practical Considerations

Ordinary time earnings (OTE) for super guarantee purposes include the salary‑sacrificed amount. So your employer’s 12% contribution is calculated on your pre‑sacrifice earnings.
Penalty rates, overtime, and allowances are usually based on the base rate of pay, not the sacrificed amount. Check your award or agreement.
Tax benefits from salary sacrifice reduce your assessable income, but the Medicare levy (2% once annualised ordinary gross reaches $30,000) and the low‑income tax offset still apply. The ATO’s shade‑in thresholds affect the actual tax outcome.

Where to Find More Information

For a detailed explanation of which pay floor applies to you, see Which minimum wage applies and Rate tables. Our Guides section covers salary sacrifice and super in more depth. The figures on this site are based on official sources: the Fair Work Commission, the Fair Work Ombudsman, the Australian Bureau of Statistics (ABS), and the ATO.

Summary

Super salary sacrifice is a useful tool for boosting retirement savings, but it must not undermine your minimum wage entitlements. Your base pay must always meet the legal floor (national minimum or award rate), and your employer must pay super on your full ordinary time earnings. If you are unsure whether your arrangement complies, consult the Fair Work Ombudsman or a workplace relations professional.
