Salary Sacrifice Charity and the Australian Minimum Wage: What You Need to Know

Salary Sacrifice Charity and Your Pay Floor

When you arrange a salary sacrifice charity deduction, your employer redirects part of your pre-tax salary to a registered charity. This can reduce your taxable income, but it does not change the minimum wage that must appear in your bank account each pay period. Understanding how the legal pay floor applies is essential for both employees and employers.

The Legal Minimum Wage Remains Unchanged

The Fair Work Commission sets the national minimum wage each year. 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. This is the absolute minimum for award-free and agreement-free employees in the national system. Casual employees receive a loading of 25%, making the casual minimum $33.05 per hour. These rates apply regardless of any salary sacrifice arrangement. Your employer must pay you at least these amounts in cash before any salary sacrifice deduction is taken. Superannuation is an additional employer payment of 12% on top of your ordinary time earnings.

If you are award-free and under 21, junior percentage rates apply. For example, a 17-year-old award-free employee must receive at least $15.29 per hour (57.8% of the adult rate), or $19.11 per hour casual. Salary sacrifice cannot reduce these minimums. The same principle applies to apprentices and trainees, who follow the Miscellaneous Award rates.

Award Coverage and Salary Sacrifice

Most Australian employees are covered by a modern award. Awards set minimum wages that are often higher than the national minimum. From the first full pay period on or after 1 July 2026, award minimum wages rise by 4.75%, but the lowest ongoing classification cannot fall below the national minimum of $26.44 per hour. Introductory rates for the first six months are capped at $25.74 per hour or $978.10 per week. If your award specifies a higher rate for your job, that is your minimum cash wage. Salary sacrifice to a charity cannot reduce your pay below that award rate. The Fair Work Ombudsman explains and enforces award conditions.

Superannuation Guarantee

Employers must pay superannuation guarantee contributions of 12% on your ordinary time earnings. Ordinary time earnings are the amount you earn for your ordinary hours of work, including any salary sacrifice amounts (unless the sacrifice is to super itself). So if you salary sacrifice $100 per week to a charity, your employer still calculates super on your full ordinary time earnings before the sacrifice. This ensures your retirement savings are not reduced by the arrangement.

Negotiated Salaries and Enterprise Agreements

Some employees negotiate individual salaries or are covered by enterprise agreements. These can set rates higher than the award or national minimum, but never lower. A salary sacrifice charity arrangement is a separate agreement between you and your employer. It does not change the minimum wage obligation. If your enterprise agreement specifies a base rate, that base rate must be paid in cash before any salary sacrifice deduction.

Summary

Salary sacrifice to a charity is a tax-effective way to support a cause, but it does not alter your entitlement to the legal minimum wage. The Fair Work Commission sets the floor; the Fair Work Ombudsman enforces it. Whether you are award-free, award-covered, or on an enterprise agreement, your cash pay must meet the applicable minimum. For more detail on which minimum applies to you, see Which minimum wage applies and Rate tables. Always check your award or agreement, and remember that super is paid on top of your ordinary time earnings.
