Does salary sacrifice into super reduce the amount of super my employer must pay?

No. Under the Superannuation Guarantee (Administration) Act, salary sacrificed amounts that would otherwise be ordinary time earnings (or qualifying earnings from 1 July 2026) remain part of your super guarantee base. Your employer must still pay 12% super on those sacrificed earnings. For example, if you sacrifice $500 of your $2,500 fortnightly wage into super, your qualifying earnings are still $2,500, and your employer's super contribution is 12% of that.

Can salary sacrifice bring my cash wage below the national minimum wage?

No. The Fair Work Act requires that your base rate of pay (the cash amount before any sacrifice) cannot fall below the applicable minimum wage. If you are award-free and an adult, your base rate must be at least $26.44 per hour. Salary sacrifice arrangements can only reduce your take-home pay, not the base rate used to check compliance with the minimum wage.

How do I know if I am award-free or covered by an award?

Most employees in the national system are covered by a modern award if their occupation and industry are listed. You can check on the Fair Work Ombudsman website or use our [Which minimum wage applies](/) guide. If no award applies and no enterprise agreement covers you, you are award-free and the national minimum wage (or a special rate for juniors, apprentices, etc.) is your floor.

Salary sacrifice into super calculator: How it affects your minimum wage and super guarantee

From 1 July 2026, the national minimum wage is $26.44 per hour ($1,004.90 per week) for award-free adult employees, with super guarantee of 12% on top of ordinary time earnings.

Salary sacrifice into super calculator and the minimum wage

When you use a salary sacrifice into super calculator, you are typically working out how much of your pre-tax salary you can direct into your super fund and how that affects your take-home pay. However, from a minimum wage perspective, the key question is whether salary sacrifice changes the legal pay floor or the super guarantee your employer must pay. The answer is no – with important nuances.

The legal minimum: award-free versus award-covered

Australia’s pay system has two main layers. The national minimum wage is set by the Fair Work Commission . From 1 July 2026, it is $26.44 per hour ($1,004.90 per week for 38 ordinary hours) for adult award-free employees. Casual employees receive a 25% loading, making the casual rate $33.05 per hour. However, not every worker must receive $26.44. Junior employees (under 21), apprentices, trainees, and supported wage employees have lower special rates. For example, a 17-year-old award-free junior receives $15.29 per hour (57.8% of the adult rate) and a casual junior $19.11.

If you are covered by a modern award, the award sets a minimum rate for your classification. From the first full pay period on or after 1 July 2026, award minimum wages rose by 4.75%, but the lowest ongoing classification cannot fall below the national minimum wage ($26.44). An introductory rate (first 6 months) cannot be less than $25.74 per hour or $978.10 per week. An enterprise agreement can also set a higher rate.

Salary sacrifice and the super guarantee

The Australian Taxation Office explains that from 1 July 2026, super guarantee is calculated on qualifying earnings . Qualifying earnings include ordinary time earnings – payments for ordinary hours of work, commissions, and certain leave. Importantly, if you salary sacrifice part of your wage into super, that sacrificed amount remains part of your qualifying earnings. Your employer must still pay 12% super on it. A salary sacrifice into super calculator that ignores this rule would underestimate your super.

Separating the floors

Legal minimum: The national minimum wage or award rate. This is the lowest base rate an employer can pay you in cash (before any sacrifice). Salary sacrifice cannot reduce this base rate.
Survey average: The ABS May 2026 figure for full-time adult ordinary-time earnings is $2,083.70 per week. This is an average, not a floor. Many workers earn less.
Award rate: If your award applies, your classification rate is your minimum. It may be higher than the national minimum.
Negotiated salary: You can agree to a higher salary than the minimum. Salary sacrifice can then reduce your take-home pay but not the base rate.

Practical example

Mika earns $2,500 per fortnight. Under a salary sacrifice arrangement, $500 goes directly into super. Mika’s qualifying earnings are still $2,500. Her employer pays 12% super on $2,500 ($300). Mika’s cash wage is $2,000, but her base rate of $2,500 per fortnight ($32.89 per hour) is well above the national minimum. If Mika were award-free and earned only $1,004.90 per week, she could not sacrifice any amount that would bring her cash wage below that floor.

Using our resources

To check which minimum applies to you, see our Rate tables and Guides. Remember, super is an employer payment on top of your wage – it does not count towards meeting the minimum wage. Always confirm your award or agreement, as it can require a higher rate than the national minimum.

Key takeaway

A salary sacrifice into super calculator is useful for budgeting, but it does not change your legal entitlements. Your employer must still pay you at least the applicable minimum wage in cash and 12% super on your full ordinary time earnings, including any sacrificed amounts.
