How salary sacrifice superannuation changes your take-home pay

Salary sacrifice superannuation is an arrangement where you and your employer agree to divert part of your pre-tax salary into your super fund. The Australian Taxation Office explains that these contributions are treated as employer contributions and are not subject to PAYG withholding. This reduces your taxable income, meaning you pay less income tax and Medicare levy. But it also reduces the cash that reaches your bank account each pay cycle.

The mechanics of salary sacrifice

Under a salary sacrifice agreement, your employer pays the sacrificed amount directly to your super fund. Your super guarantee (currently 12% from 1 July 2026) is still calculated on your full salary before the sacrifice – the ATO confirms that salary sacrifice does not reduce your super guarantee entitlement. The sacrificed amount is taxed at 15% inside your super fund, which is generally lower than your marginal tax rate. Moneysmart notes that salary packaging can reduce your tax, but the items or services you receive cannot be claimed as deductions.

Impact on your fortnightly pay

Let’s say you earn $60,000 a year. Without salary sacrifice, your tax (excluding Medicare) is $8,520 under the 2026–27 rates, and the Medicare levy adds 2% ($1,200). Your take-home pay is about $50,280 annually, or $1,933 per fortnight. If you salary sacrifice $5,000 a year into super, your taxable income drops to $55,000. Tax becomes $7,020, Medicare levy $1,100, and take-home pay $46,880 – a reduction of $3,400 in cash. But you have $5,000 in super (after 15% tax, $4,250) instead of the $3,400 you would have had after tax if you took it as cash. The net benefit is $850 more in super.

Comparing with benchmarks

The national minimum wage is $26.44 an hour and $1,004.90 a week. Full-time adult ordinary time earnings average $2,083.70 per week. If you earn around the average, salary sacrifice can be more impactful because your marginal rate is higher. For example, on $108,352 (full-time ordinary time), the 30% bracket applies, so each dollar sacrificed saves 30c in tax plus 2c Medicare. The trade-off is lower cash flow, but faster super growth.

Medicare levy considerations

The Medicare levy is 2% of your taxable income. Reducing your taxable income through salary sacrifice also reduces your Medicare levy. The latest single-person thresholds are $28,011 and $35,013. If your taxable income falls below $28,011 after sacrifice, you pay no Medicare levy. Between $28,011 and $35,013, a shading-in applies. This can be a useful strategy if you are close to these thresholds.

Important limits and rules

• Concessional cap: The amount you can contribute at the 15% tax rate is capped each year. Exceeding the cap means the excess is taxed at your marginal rate.
• Division 293 tax: If your combined income and concessional contributions exceed $250,000, an additional 15% tax applies.
• No FBT: Salary sacrifice super is not a fringe benefit, so no FBT applies.
• Reportable super: The sacrificed amount is included in your reportable super contributions and must be shown in your tax return.

Should you salary sacrifice?

Salary sacrifice superannuation is most beneficial if you are in a higher tax bracket and can afford the reduction in take-home pay. It is a long-term strategy to boost retirement savings.
