How salary sacrifice into super changes your take-home pay when comparing job offers

Why your take-home pay matters more than the advertised salary

When you compare job offers, the headline figure can be misleading. What really counts is the amount that lands in your bank account each fortnight after income tax and the Medicare levy. One way to change that number is through salary sacrifice into super – an arrangement where you swap part of your pre-tax salary for extra super contributions. The Australian Taxation Office explains that this reduces your taxable income, so you pay less tax. But it also means less cash in hand now. This guide helps you weigh the trade-off.

How salary sacrifice into super works

Salary sacrifice into super is a type of salary packaging. You and your employer agree to divert some of your before-tax pay into your super fund. The Australian Taxation Office notes that these are treated as employer contributions, not personal ones. Your employer must still pay the full super guarantee on your original salary – the sacrificed amount does not reduce their obligation. The contributions are taxed inside your super fund at 15%, which is usually lower than your marginal income tax rate. Because the sacrificed amount is not included in your assessable income, you pay less income tax and Medicare levy on your remaining salary.

The impact on your take-home pay

Your take-home pay is what remains after tax and the Medicare levy are withheld. For the 2026-27 tax year, the rates are:

• 0% on the first $18,200
• 15c per dollar from $18,201 to $45,000
• 30c per dollar from $45,001 to $135,000
• 37c per dollar from $135,001 to $190,000
• 45c per dollar over $190,000

Plus the Medicare levy of 2% (with reduced rates for singles earning between $28,011 and $35,013).

If you salary sacrifice $5,000 into super, your taxable income drops by $5,000. At a marginal rate of 30c, you save $1,500 in tax plus $100 in Medicare levy – an extra $1,600 in your pocket each year. But that $5,000 goes into super, not your bank account. So your fortnightly pay will be lower than if you had taken the full salary. You need to decide whether the long-term super boost is worth the short-term cash reduction.

Comparing job offers with salary sacrifice options

When you look at two offers, consider the total remuneration package. One employer might offer a higher base salary but no salary sacrifice arrangement. Another might offer a slightly lower base but allow you to salary sacrifice into super. To compare fairly:

1. Calculate the take-home pay from each offer using the tax rates above and the Take-home pay guide.
2. Add the value of any salary sacrifice into super you plan to use. Remember, the sacrificed amount is not taxed now, but it grows in super and will be taxed when you withdraw it.
3. Check the concessional contributions cap. Moneysmart notes the yearly limit is $32,500 for 2026-27, which includes your employer's super guarantee. If you exceed it, you may pay extra tax.

For example, if you earn $80,000 and your employer pays 12% super ($9,600), you have $22,900 of cap left. Sacrificing $10,000 would keep you under the cap and save you about $3,200 in tax and Medicare. Your take-home pay would drop by roughly $10,000 minus the tax saved, so about $6,800 less cash per year. But your super balance grows by $10,000 plus earnings.

Other factors to consider

• Division 293 tax: If your combined income and concessional contributions exceed $250,000, an extra 15% tax applies to some of your super contributions.
• Medicare levy surcharge: If you don't have appropriate private hospital cover and your income is above a threshold, you may pay an extra 1% to 1.5%. Salary sacrifice into super can reduce your income for this test.
• Employer policies: Not all employers offer salary sacrifice into super. Check your contract or ask HR.

Bottom line

Salary sacrifice into super can be a smart way to boost your retirement savings while lowering your tax bill. But it reduces the cash you have to spend now. When comparing job offers, always look at the net amount that reaches your account after tax and Medicare, and factor in any sacrifice you plan to make. Use the Super guide to estimate your long-term benefit. And remember, the national minimum wage is $26.44 an hour or $1,004.90 a week – a useful benchmark if an offer seems low.
