Can I salary sacrifice below the minimum wage?

No. Salary sacrifice cannot reduce your cash pay below the applicable minimum wage, award rate, or enterprise agreement rate. The Fair Work Ombudsman requires that your base rate of pay after any salary sacrifice arrangement still meets the legal minimum. Any agreement that brings your effective hourly rate under the floor is void.

How does salary sacrifice affect superannuation?

Salary sacrifice contributions are generally subject to the super guarantee of 12% on ordinary time earnings. However, if you sacrifice salary into super, your ordinary time earnings for super calculation may be reduced depending on the arrangement. Check with your employer or payroll provider to ensure compliance with super guarantee obligations.

What is the tax benefit of salary sacrifice?

Salary sacrifice reduces your taxable income, potentially lowering your income tax and Medicare levy. For the 2026–27 tax year, resident rates with the full tax-free threshold apply, and Medicare is estimated at 2% once annualised ordinary gross reaches $30,000. The ATO provides tax tables to estimate net pay after sacrifice. Note that salary sacrifice does not change the minimum wage floor.

Calculating salary sacrifice: how it interacts with Australia's minimum wage

The national minimum wage is $26.44 per hour or $1,004.90 per week from 1 July 2026, but salary sacrifice arrangements must not reduce your pay below this floor.

Understanding salary sacrifice and the minimum wage

When calculating salary sacrifice, it is essential to know how it interacts with Australia’s minimum wage system. Salary sacrifice is an arrangement where an employee agrees to forgo part of their salary or wages in exchange for benefits such as additional superannuation contributions, a car, or other non-cash items. While this can reduce taxable income, it must never push your effective hourly or weekly pay below the legal floor.

The legal minimum wage floor

The Fair Work Commission sets the national minimum wage. 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 ordinary week. Casual employees receive a loading of 25%, making the casual rate $33.05 per hour. These figures apply to national‑system employees who are award‑free and agreement‑free. Most private‑sector workers are in the national system, though some state public sector and local government employees may be covered by state awards.

Modern awards and enterprise agreements can set higher rates. For example, the lowest ongoing classification in a modern award cannot sit under the national minimum, and introductory rates (limited to the first six months) cannot fall below $25.74 per hour or $978.10 per week. Award‑free junior employees have percentage‑based rates (e.g., 18‑year‑olds receive 68.3% of the adult rate, or $18.06 per hour). Apprentice and trainee rates for award‑free employees follow the Miscellaneous Award.

Employers must also pay the super guarantee of 12% on top of ordinary time earnings. This is an employer cost, not deducted from the employee’s base rate.

How salary sacrifice fits in

Salary sacrifice is a voluntary arrangement between you and your employer. It reduces your gross salary for tax purposes, but the base rate of pay – the cash component – must still meet the minimum wage or applicable award rate. The Fair Work Ombudsman explains that salary sacrifice cannot reduce your pay below the legal minimum. For instance, if you earn exactly the national minimum of $26.44 per hour, you cannot sacrifice any of that cash wage because you would then fall below the floor. Salary sacrifice is typically used by employees earning above the minimum.

When calculating salary sacrifice, remember that the sacrificed amount is not subject to PAYG withholding, but it may affect other entitlements such as leave loading, overtime, and super guarantee calculations. Always check your award or agreement, as some awards limit the types of salary sacrifice allowed.

Comparing with average earnings

The Australian Bureau of Statistics (ABS) reported that in May 2026, full‑time adult ordinary‑time earnings averaged $2,083.70 per week, while all employees averaged $1,579.20 per week. These figures are significantly higher than the national minimum wage. Salary sacrifice is more common among higher earners who can afford to redirect part of their salary into super or other benefits. However, even on the minimum wage, you can still make personal after‑tax super contributions if you wish.

Tax and Medicare considerations

For the 2026–27 tax year, resident tax rates with the full tax‑free threshold apply. Medicare is estimated at 2% once annualised ordinary gross income reaches $30,000. Salary sacrifice reduces your taxable income, which may lower your tax bracket and Medicare levy. However, the ATO’s low‑income tax offset and the Medicare levy surcharge are not considered in this simple model. Always use the ATO’s tax tables or consult a tax professional for your specific situation.

Summary

When calculating salary sacrifice, always start with the legal minimum wage: $26.44 per hour or $1,004.90 per week from 1 July 2026. Your salary sacrifice arrangement must not reduce your cash pay below this floor. Superannuation of 12% is paid on top by your employer. Award or agreement rates may be higher, and you cannot sacrifice below those either. Use the ABS average earnings as a benchmark, but remember that the minimum wage is the safety net.
