Salary sacrifice WA: How it interacts with minimum wage and award rates

Salary sacrifice WA: Understanding your minimum wage obligations

Salary sacrifice in Western Australia (WA) is a common way to reduce your taxable income by swapping part of your before-tax salary for benefits like a car, electronic devices, or extra super contributions. However, salary sacrifice does not change the minimum wage or award rate you must legally receive. This guide explains how salary sacrifice interacts with the national minimum wage, modern awards, and the super guarantee, and what you need to check if you are in the WA state system.

The legal minimum wage floor

From 1 July 2026, the adult national minimum wage is $26.44 per hour, or $1,004.90 per week for a 38-hour week. Casual employees receive a loading of 25%, making the casual rate $33.05 per hour. These rates apply to national-system employees who are award-free and agreement-free. Most private-sector employees in WA are in the national system, but some state public sector and local government employees, and some sole traders and partnerships, are covered by state awards instead.

Salary sacrifice does not reduce this floor. Your employer must pay you at least the minimum wage or the applicable award rate before any salary sacrifice arrangement. For example, if you agree to salary sacrifice $100 per week for a car, your gross salary must still be at least $1,004.90 per week (if you are an adult award-free employee). The sacrificed amount comes out of your pay after the minimum wage obligation is met.

Award rates and salary sacrifice

If you are covered by a modern award, your base rate of pay must be at least the minimum rate for your classification. From the first full pay period on or after 1 July 2026, modern award minimum wages rise by 4.75%, but the lowest ongoing classification cannot sit under the national minimum of $26.44 per hour. Introductory rates (first 6 months) cannot sit under $25.74 per hour or $978.10 per week.

Salary sacrifice does not allow your employer to pay you less than the award rate. Your award may also have specific rules about salary sacrifice, such as how it affects overtime or penalty rates. Always check your award or enterprise agreement. If you are award-free, the national minimum wage applies, but an enterprise agreement can set a higher rate.

Super guarantee on top

Employers must pay super guarantee of 12% on your ordinary time earnings. Ordinary time earnings are the gross salary before any salary sacrifice. So if you salary sacrifice part of your salary, your super guarantee is still calculated on the full amount you would have earned without the sacrifice. This protects your retirement savings. For example, if your ordinary time earnings are $1,004.90 per week, your employer must contribute $120.59 in super (12% of $1,004.90), even if you sacrifice $100 of that salary.

WA state system considerations

WA has a separate state industrial relations system for some employees, including state public sector workers and local government employees. If you are in the state system, your minimum wages and conditions are set by state awards or the WA Industrial Relations Commission. Salary sacrifice rules may differ slightly, but the principle remains: salary sacrifice cannot reduce your minimum wage or award rate. Check with the WA Department of Mines, Industry Regulation and Safety or your union for state-specific guidance.

Practical check for your hourly rate

To see if your salary sacrifice arrangement is lawful, compare your gross hourly rate (before sacrifice) to the legal floor. If you are an adult award-free employee, your gross rate must be at least $26.44 per hour. If you are on a modern award, find your classification rate. If you are a junior, apprentice, or trainee, different rates apply (see the junior percentages in the reference). Remember, salary sacrifice is a voluntary agreement between you and your employer. It cannot be used to pay you below the minimum.
