Salary sacrificing into super and the minimum wage: what you need to know

Understanding salary sacrificing into super and the minimum wage

Salary sacrificing into super is an arrangement where you agree to forgo part of your pre-tax salary in exchange for your employer paying that amount into your superannuation fund. It can be a tax-effective way to boost your retirement savings, but it must not put you below the legal minimum wage. This guide explains how the minimum wage floor, award rates, and super guarantee interact with salary sacrificing into super.

The legal minimum wage floor

The national minimum wage is set by the Fair Work Commission and enforced by the Fair Work Ombudsman. From the first full pay period on or after 1 July 2026, the adult national minimum wage is $26.44 per hour or $1,004.90 per week for a 38‑hour week. This is the minimum cash amount you must receive for your work before any salary sacrifice arrangement. If you are covered by a modern award or enterprise agreement, the minimum rate in that instrument applies instead, and it may be higher than the national minimum. The lowest ongoing classification in a modern award cannot fall below $26.44 per hour, and introductory rates (limited to the first six months) cannot fall below $25.74 per hour or $978.10 per week.

Salary sacrificing into super cannot reduce your cash wage below the applicable minimum. For example, if you earn exactly the national minimum of $1,004.90 per week, you cannot sacrifice any amount into super because your cash wage would then be less than $1,004.90. Salary sacrifice is only possible when your gross wage is above the minimum, so that the cash component after sacrifice still meets the legal floor.

How salary sacrifice affects your weekly packet

When you salary sacrifice into super, your taxable income decreases, but your employer must still pay the super guarantee (12% from 1 July 2026) on the sacrificed amount. The ATO confirms that salary sacrificed amounts to super are qualifying earnings for super guarantee purposes. So if you sacrifice $100 from a gross wage of $1,200, your employer pays 12% on the full $1,200 ($144) – not just on the $1,100 cash you receive.

To see how this works with the minimum wage, consider an employee earning the national minimum of $1,004.90 per week. They cannot salary sacrifice because the cash wage would drop below the floor. But an employee earning, say, $1,200 per week could sacrifice $195.10 into super, leaving a cash wage of $1,004.90 (the minimum). The employer would then pay 12% super on $1,200 ($144), not just on $1,004.90. This is a key benefit of salary sacrificing into super.

Comparing with award rates and average earnings

Award rates often set higher minimums than the national minimum. For example, many awards have classifications above $26.44 per hour. If you are covered by an award, you must be paid at least the award rate in cash before any salary sacrifice. The Fair Work Commission’s Modern Awards Pay Database contains the calculated minimum rates, allowances, and penalty rates for each award. You can check your award using the Which minimum wage applies guide or the Rate tables on this site.

The Australian Bureau of Statistics reported that in May 2026, full‑time adult ordinary‑time earnings averaged $2,083.70 per week. This is well above the minimum, meaning most full‑time employees have room to salary sacrifice into super without breaching the floor. However, part‑time or casual employees on award rates may have less flexibility.

Super guarantee on top

Remember that the super guarantee is an employer payment on top of your wage. The national minimum wage of $26.44 per hour does not include super; the employer must pay an additional 12% into your super fund. When you salary sacrifice into super, the sacrificed amount is still treated as ordinary time earnings, so the employer’s super obligation does not decrease. This makes salary sacrificing into super an efficient way to increase your retirement savings without reducing your employer’s contribution.

Important distinctions

• Legal minimum: The national minimum wage or award minimum – the floor that cannot be undercut by salary sacrifice.
• Survey average: ABS average earnings – a benchmark, not a legal requirement.
• Award rate: The minimum set by a modern award for your classification and industry.
• Negotiated salary: Your actual pay, which may be above the minimum and can include salary sacrifice arrangements.
