Can salary sacrifice reduce my cash pay below the minimum wage?

No. The base rate of pay (the rate before any salary sacrifice) must be at least the national minimum wage or the applicable award rate. Salary sacrifice reduces the cash you receive, but the base rate remains unchanged. Your employer cannot pay you a base rate below the legal minimum, even if you agree to sacrifice part of your salary into super.

Does salary sacrifice reduce the employer's super guarantee obligation?

No. The super guarantee is calculated on your ordinary time earnings (OTE), which is generally your base salary or wage before salary sacrifice. Salary sacrifice contributions count towards the employer's 12% obligation, but the employer must still contribute at least 12% of your OTE. If your salary sacrifice into super is less than 12% of OTE, the employer must make up the difference.

Salary sacrifice superannuation employer obligations: what you need to know

Q: Are award-covered employees allowed to salary sacrifice into super?

Yes, but the arrangement must comply with the award and any enterprise agreement. The award rate remains the minimum base rate, and salary sacrifice cannot reduce that base rate. Some awards may have specific rules about salary sacrifice, so check your award or seek advice from the Fair Work Ombudsman.

The legal minimum cash rate is $26.44 per hour or $1,004.90 per week, with super guarantee of 12% on top; salary sacrifice does not reduce this base rate or the super obligation.

Understanding salary sacrifice superannuation employer obligations

When an employee agrees to salary sacrifice part of their pay into superannuation, the employer still has clear obligations under the Fair Work Act and superannuation law. The key point is that salary sacrifice does not change the legal minimum cash rate or the employer's super guarantee requirement. This guide explains how salary sacrifice interacts with the national minimum wage, award rates, and super guarantee, with a focus on award coverage versus award-free employment.

The legal minimum cash rate

The national minimum wage from 1 July 2026 is $26.44 per hour or $1,004.90 per week for a full-time adult employee. Casual employees receive a loading of 25%, making the casual minimum $33.05 per hour. These are the cash rates before any salary sacrifice. The employer must also pay super guarantee of 12% on top of ordinary time earnings.

For award-covered employees, the modern award sets a higher minimum cash rate for the classification. The award rate is the base rate, and salary sacrifice cannot reduce that base rate. Award-free employees who are not covered by an agreement must receive at least the national minimum wage. Junior, apprentice, and trainee rates may be lower, as set out in the award or the Miscellaneous Award for award-free employees.

How salary sacrifice affects super guarantee

The super guarantee is 12% of the employee's ordinary time earnings (OTE). OTE is generally the salary or wages the employee earns for their ordinary hours, before any salary sacrifice. If an employee salary sacrifices part of their salary into super, that contribution is treated as an employer contribution for super guarantee purposes. However, the employer must still ensure that total super contributions (including the salary sacrifice amount) equal at least 12% of OTE. If the salary sacrifice amount is less than 12%, the employer must pay the difference.

Importantly, salary sacrifice does not reduce the employer's obligation to pay super on the full OTE. The employer cannot use salary sacrifice to avoid paying the 12% minimum. The employee's cash pay will be lower, but the base rate for super calculations remains unchanged.

Award coverage versus award-free rates

For award-covered employees, the award rate is the minimum base rate. Salary sacrifice arrangements must not bring the cash pay below that base rate. Some awards restrict salary sacrifice or require written agreement. For award-free employees, the national minimum wage is the floor. In both cases, the employer must pay super on the base rate, not on the reduced cash amount.

Enterprise agreements may also set higher rates or specific rules about salary sacrifice. If an agreement applies, its terms prevail over the award or national minimum wage, as long as they do not undercut the safety net.

Survey average and negotiated salaries

The ABS reports that full-time adult ordinary-time earnings averaged $2,083.70 per week in May 2026. This is well above the minimum wage. Many employees negotiate salaries above the award or minimum, and salary sacrifice is often used to reduce tax on higher incomes. However, the legal minimum remains the floor, and super obligations apply to the full OTE regardless of the salary level.
