Retirement savings salary sacrifice: checking your hourly rate against the minimum wage

Retirement savings salary sacrifice and the minimum wage

Salary sacrificing part of your pay into superannuation is a common way to boost retirement savings while reducing your taxable income. However, it cannot reduce your hourly rate below the legal minimum. This guide helps you check whether your arrangement keeps you above the pay floor.

The legal minimum wage floor

The Fair Work Commission sets the national minimum wage. From the first full pay period on or after 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 $33.05 per hour. The employer must also pay the 12% super guarantee on top of ordinary time earnings. These rates apply to national‑system employees who are not covered by a modern award or enterprise agreement. If you are award‑free and agreement‑free, this is your legal floor. For more detail on which minimum applies to you, see Which minimum wage applies.

How salary sacrifice interacts with the minimum wage

Salary sacrifice reduces your gross salary in exchange for a benefit—usually extra super contributions. But the Fair Work Ombudsman explains that the arrangement cannot reduce your base rate of pay below the minimum wage. Your cash hourly rate after the sacrifice must be at least $26.44 (or the relevant award rate if higher). For example, if you earn $30 per hour and sacrifice $5 per hour into super, your cash rate becomes $25 per hour, which is below the minimum. That is not permitted. You must adjust the sacrifice amount so that your cash rate stays above the floor.

Award and agreement rates

Many employees are covered by a modern award or an enterprise agreement. These instruments often set higher minimum rates than the national minimum wage. The award backstop from 1 July 2026 is $26.44 per hour for ongoing employees, but introductory rates (first six months) are $25.74 per hour. Junior, apprentice, and trainee rates also differ. If your award or agreement specifies a higher rate, that becomes your minimum. Your salary sacrifice must not bring your cash rate below that higher figure. See Rate tables for current award minimums.

Super guarantee on top

Remember that the super guarantee is an employer payment on top of your ordinary time earnings. The 12% contribution is calculated on your ordinary time earnings before any salary sacrifice. Salary sacrifice contributions are additional and do not reduce the employer’s obligation. So your total super contributions (mandatory plus sacrificed) can be higher, but the minimum wage check is about your cash hourly rate, not your total package.

Practical check for your hourly rate

To see if your salary sacrifice arrangement is lawful, follow these steps:

1. Find your gross annual salary (before sacrifice).
2. Divide by 52 to get weekly gross.
3. Divide by your ordinary weekly hours (usually 38) to get your hourly rate before sacrifice.
4. Subtract the hourly equivalent of your salary sacrifice amount.
5. Compare the result to $26.44 (or your award rate).

If the cash rate is below the floor, you need to reduce the sacrifice amount or increase your base salary. This check is a starting point—it does not replace professional advice.

Other considerations

Salary sacrifice can affect your tax, Medicare levy, and eligibility for certain offsets. The ATO provides guidance on how salary sacrifice interacts with the tax‑free threshold and the low‑income tax offset. This site does not give tax advice.

Always check your pay slip and compare your cash hourly rate to the relevant minimum. If you suspect an underpayment, contact the Fair Work Ombudsman.
