Can a salary sacrifice form reduce my pay below the minimum wage?

No. Under the Fair Work Act, salary sacrifice cannot reduce your base rate of pay below the minimum award rate or the national minimum wage. You must always receive at least the minimum cash amount for each hour worked.

How does salary sacrifice affect my super guarantee?

Generally, salary sacrifice contributions are included in your ordinary time earnings for super guarantee purposes, so your employer must still pay 12% super on top of your salary sacrifice amount. However, some arrangements may have specific rules – check with your employer or the ATO.

Does the salary sacrifice form affect my tax and Medicare?

Yes. Salary sacrifice reduces your taxable income, which may lower your income tax and Medicare levy. However, the Medicare levy still applies once your annualised ordinary gross income exceeds $30,000. The ATO provides a low-income reduction for those earning under certain thresholds. Use the ATO's tax calculator for your specific situation.

Salary sacrifice form and the minimum wage: what you need to know

The national minimum wage from 1 July 2026 is $26.44 per hour or $1,004.90 per week for adults, with super guarantee of 12% on top. A salary sacrifice arrangement cannot reduce your cash pay below this floor.

Salary sacrifice form and the minimum wage

When you fill out a salary sacrifice form, you are agreeing to forgo part of your pre-tax salary in exchange for benefits such as super contributions, a car, or electronic devices. This arrangement can reduce your taxable income, but it must never push your cash pay below the legal minimum. This guide explains how the salary sacrifice form fits with Australia's pay floors, tax, Medicare, and super.

The legal minimum

The Fair Work Commission sets the national minimum wage. From 1 July 2026, the adult rate is $26.44 per hour or $1,004.90 per week for a 38‑hour week. Casual employees receive a 25% loading, making the casual minimum $33.05 per hour. These figures apply to national‑system employees who are not covered by a modern award or enterprise agreement. If you are award‑free and agreement‑free, your base rate of pay cannot be less than the national minimum. A salary sacrifice form cannot reduce your cash earnings below this floor.

Award rates and enterprise agreements

Many employees are covered by a modern award, which sets minimum wages for specific industries and occupations. From the first full pay period on or after 1 July 2026, award minimum wages rise by 4.75%. The lowest ongoing classification in an award cannot sit under the national minimum of $26.44 per hour. Introductory rates (first six months) are capped at $25.74 per hour or $978.10 per week. An enterprise agreement may also set higher rates. If your award or agreement requires a higher base rate, your salary sacrifice arrangement must still leave you with at least that higher cash amount. Always check your award or agreement before signing a salary sacrifice form.

Award‑free juniors and other categories

For award‑free employees under 21, junior percentages apply. For example, a 17‑year‑old must receive at least $15.29 per hour (or $19.11 casual). Apprentices and trainees follow the Miscellaneous Award rates. Salary sacrifice cannot reduce these minimums. The Fair Work Ombudsman provides guidance on junior and supported wage rates.

Super guarantee on top

Employers must pay super guarantee of 12% on ordinary time earnings. This is on top of the cash wage. Salary sacrifice contributions are generally included in ordinary time earnings, so your employer still pays super on the sacrificed amount. However, if you sacrifice into super, the super guarantee may already be satisfied by those contributions – check with your employer. The super payment is separate from the minimum cash wage and does not count towards meeting the minimum.

Tax and Medicare considerations

Salary sacrifice reduces your taxable income, which can lower your income tax and Medicare levy. For the 2026‑27 tax year, resident rates apply with the full tax‑free threshold. Medicare is estimated at 2% once annualised ordinary gross income reaches $30,000. The ATO provides a low‑income reduction for those earning under certain thresholds. This site’s model leaves out the low income tax offset, HELP repayments, salary sacrifice, and the Medicare levy surcharge. Use the ATO’s tax calculator for your personal situation. Remember that salary sacrifice does not affect the Medicare levy surcharge if you are single and earn above the threshold.

How your pay compares

The ABS May 2026 survey shows full‑time adult ordinary‑time earnings of $2,083.70 per week and all‑employee average total earnings of $1,579.20 per week. The national minimum of $1,004.90 is well below these averages. If you earn above the minimum, a salary sacrifice form can be a useful way to reduce tax, but you must ensure your cash pay remains above the legal floor. For award‑free employees, the minimum is the national minimum; for award‑covered employees, it is the award rate.

Summary

A salary sacrifice form is a tool to manage your tax, but it must never reduce your cash pay below the applicable minimum wage. The national minimum from 1 July 2026 is $26.44 per hour ($1,004.90 per week) for adults, with 12% super on top. Award and agreement rates may be higher. Always check your award or agreement before signing, and consult the Fair Work Ombudsman or a tax professional if you are unsure.
