How retirement savings salary sacrifice affects your take-home pay
Your take-home pay depends on how much you salary sacrifice; the national minimum wage is $26.44 per hour ($1,004.90 per week) and full-time ordinary time earnings average $2,083.70 per week.
How retirement savings salary sacrifice changes your after-tax pay
When you agree to a retirement savings salary sacrifice arrangement, you swap part of your salary for extra super contributions. This lowers your taxable income, which reduces the income tax and Medicare levy you pay. But it also means less cash reaches your bank account each pay period.
What is salary sacrifice for super?
Salary sacrifice is an agreement with your employer to divert some of your pre-tax salary into your super fund. The Australian Taxation Office explains that these contributions are treated as employer super contributions and are not subject to pay-as-you-go withholding. They are taxed inside your super at 15%, which is generally less than your marginal tax rate. Your employer must still pay the full super guarantee (12% from 1 July 2026) on your original salary, not the sacrificed amount.
Impact on your take-home pay
Your take-home pay is what lands in your bank account after tax and the Medicare levy are deducted. When you salary sacrifice, your taxable income falls, so the amount withheld for tax also falls. However, the sacrificed amount is not paid to you – it goes to your super. The net effect is that your cash take-home is lower than if you had not sacrificed, but your super balance grows faster.
To see how this works, compare your situation to the national benchmarks. The Minimum wage is $26.44 per hour ($1,004.90 per week). The Average pay for full-time adult ordinary time earnings is $2,083.70 per week. If you earn around that level, salary sacrificing a portion could move you into a lower tax bracket, saving you tax at your marginal rate.
Tax rates and Medicare levy for 2026–27
For the 2026–27 income year, the resident tax rates are:
- $0 – $18,200: Nil
- $18,201 – $45,000: 15c for each $1 over $18,200
- $45,001 – $135,000: $4,020 plus 30c for each $1 over $45,000
- $135,001 – $190,000: $31,020 plus 37c for each $1 over $135,000
- $190,001 and over: $51,370 plus 45c for each $1 over $190,000
The Low Income Tax Offset (LITO) can reduce tax by up to $700 for incomes up to $37,500, then phases out. The Medicare levy is 2% of taxable income for most people. The latest single-person thresholds are $28,011 and $35,013 – if your taxable income after salary sacrifice falls below the lower threshold, you pay no Medicare levy; between the thresholds, a shading rate applies.
Example: how sacrifice changes your tax
Suppose you earn the full-time ordinary time average of $108,352 per year. Without salary sacrifice, your tax (before offsets) would be roughly $24,667 plus Medicare levy of $2,167, giving take-home around $81,518. If you salary sacrifice $10,000 into super, your taxable income drops to $98,352. Your tax falls to about $21,517, Medicare to $1,967, and take-home becomes $74,868. The $10,000 goes to super, taxed at 15% ($1,500), so your super gets $8,500. Your cash take-home is $6,650 less, but you have saved $3,650 in tax and Medicare, and your super grows by $8,500.
Considerations before you start
Salary sacrifice is not right for everyone. The ATO notes that if your combined income and concessional contributions exceed $250,000, you may pay Division 293 tax. Also, salary sacrifice counts towards your concessional contributions cap ($27,500 for 2026–27). Exceeding the cap means extra tax. Use the Clearance tool to check your situation.
Your employer must agree to the arrangement. You can change or stop it at any time, but check your employment contract. Salary sacrifice does not reduce your employer's super guarantee obligation – they must still pay 12% on your original salary.
Where salary sacrifice fits against benchmarks
The national minimum wage of $26.44 per hour gives an annual salary of about $52,255. At that level, salary sacrifice may be less beneficial because your marginal rate is only 15c (plus 2% Medicare). Sacrificing $1,000 saves you $170 in tax and Medicare, but you lose $1,000 in cash. For higher earners, the savings are larger.
Full-time ordinary time earnings of $108,352 sit in the 30c bracket. Sacrificing $10,000 saves $3,200 in tax and Medicare (30c + 2c), making it more attractive. The Salary packaging guide has more details.
Final thoughts
Retirement savings salary sacrifice can be a smart way to boost your super while reducing your tax bill. But it directly reduces your take-home pay. Always consider your cash flow needs and contribution caps. For a personalised estimate, use the Take-home pay calculator and review the Tax and Medicare page.
Questions
Does salary sacrificing super reduce my take-home pay?
Yes. When you salary sacrifice, part of your pre-tax salary goes directly into your super fund instead of your bank account. Your taxable income drops, so you pay less income tax and Medicare levy, but your cash take-home pay is lower because the sacrificed amount is not paid to you.
How is salary sacrifice treated for tax purposes?
Salary sacrifice super contributions are classified as employer contributions and are not subject to PAYG withholding. They reduce your assessable income, meaning you pay tax at your marginal rate on a smaller amount. The contributions are taxed inside your super fund at 15%, which is often lower than your marginal rate.
Can salary sacrifice affect my Medicare levy?
Yes, because the Medicare levy is 2% of your taxable income. If salary sacrifice lowers your taxable income, your Medicare levy also decreases. However, if your income after sacrifice falls below the single-person thresholds ($28,011 or $35,013), you may qualify for a reduced levy or exemption.
