Salary Sacrifice Into Super Australia 2026 — How Much Should You Contribute?

How Salary Sacrifice Into Super Works

Salary sacrifice is an agreement with your employer to redirect part of your before-tax salary into your superannuation fund instead of receiving it as take-home pay. Because the money never reaches you as salary, it isn't taxed at your marginal income tax rate. Instead it lands in your super fund as a concessional contribution and is taxed at a flat 15% inside the fund (or 30% if your combined income and concessional contributions exceed $250,000, under the Division 293 rules).

The gap between your marginal rate and that 15% contributions tax is your saving. Under the 2026-27 resident tax rates, marginal rates are 15% on income from $18,201 to $45,000, 30% up to $135,000, 37% up to $190,000, and 45% above that — plus the 2% Medicare levy for most taxpayers. So a middle-income earner is effectively giving up 32 cents of every sacrificed dollar to tax if they take it as salary, versus 15 cents if it goes into super. Salary sacrifice also reduces your taxable income, which is why it appears on so many end-of-financial-year checklists.

The trade is straightforward: less cash now, more retirement savings later, with the tax system paying part of the difference. Whether that trade suits you depends on your income, your cash-flow needs and how far you are from age 60. You can model your own numbers in our superannuation calculator and see the income-tax side in the income tax calculator.

Worked Examples: Sacrificing $500 a Month

Let's make it concrete. Suppose you sacrifice $500 per month — $6,000 per financial year — at three different salary levels, using 2026-27 rates plus the 2% Medicare levy. In each case, the $6,000 would have been taxed at your marginal rate plus Medicare if taken as salary; inside super it's taxed at 15% ($900).

Notice that the $70,000 and $95,000 earners save the same amount — the 30% bracket now stretches from $45,000 to $135,000, so a large share of workers get an identical percentage benefit. The step-up comes at higher incomes: the $150,000 earner keeps roughly $1,440 a year, about 24% of every dollar sacrificed.

The take-home cost is also smaller than the sacrifice itself. The $95,000 earner giving up $6,000 of gross pay only loses about $4,080 of after-tax income (they were only ever going to keep 68% of it), yet $5,100 lands in super after contributions tax. That asymmetry is the whole point of the strategy.

The $30,000 Concessional Cap — and Your Headroom

Concessional (before-tax) contributions are capped at $30,000 per financial year, and the cap includes your employer's compulsory Superannuation Guarantee, which is now 12% of ordinary time earnings. To work out how much you can sacrifice, subtract your expected SG from $30,000.

Worked example: on a $95,000 salary, employer SG is $95,000 × 12% = $11,400. Your salary sacrifice headroom is $30,000 − $11,400 = $18,600 for the year, or about $1,550 per month. Someone on $150,000 receives $18,000 of SG, leaving $12,000 of headroom. Bonuses, commissions and any insurance premiums your employer pays through super can also count, so leave a small buffer rather than sacrificing to the exact dollar. Excess concessional contributions are added back to your taxable income and taxed at your marginal rate, which unwinds the benefit and creates paperwork.

Carry-Forward: Catching Up on Unused Caps

If your total super balance was under $500,000 at the previous 30 June, you can use unused concessional cap amounts from up to five earlier financial years. Suppose you contributed only the SG minimum for the past few years and accumulated $25,000 of unused cap. In a year where you receive a bonus, sell an asset, or return to full-time work, you could contribute well beyond $30,000 — using this year's cap plus the carried-forward amounts — and claim the full tax benefit. Carry-forward is especially valuable after career breaks, parental leave or years of part-time work, and it pairs well with one-off windfalls. Your unused cap history is visible in ATO online services through myGov.

Salary Sacrifice vs Personal Deductible Contributions

You don't need a payroll arrangement to get the same tax outcome. A personal deductible contribution — paying money from your bank account into super and claiming a tax deduction — produces an identical net result: the contribution is taxed at 15% in the fund and your taxable income falls by the same amount. The differences are mechanical:

• Salary sacrifice happens automatically every pay cycle, before you ever see the money. Great for discipline; requires your employer to offer it; changes can take a pay cycle or two.
• Personal deductible contributions can be made any time before 30 June, in any amount, from any bank account — but you must lodge a notice of intent to claim a deduction with your fund and receive written acknowledgement before you lodge your tax return (or start a pension or roll over). Miss the notice and the deduction is lost.

Many people combine them: a modest ongoing sacrifice for dollar-cost averaging, plus a top-up personal contribution in June once they know their cap headroom for the year.

The Trade-Offs You Should Weigh First

• Your money is locked away. Contributions are preserved until you reach age 60 and meet a condition of release (generally retiring). A 35-year-old is committing that money for 25 years. Don't sacrifice money you may need for a home deposit (outside FHSS), an emergency fund, or high-interest debt — paying off a 20%+ credit card beats a 17-point tax saving every time.
• Cash flow. Your take-home pay drops from the first adjusted pay cycle. Start small — even $100 per fortnight — and increase it once you've confirmed your budget absorbs it.
• The HECS-HELP trap. This one catches people every year. Your HELP repayment income is your taxable income grossed back up by reportable super contributions — salary sacrifice is added straight back. So sacrificing does not reduce the income your compulsory HELP repayment is calculated on. Worse, payroll withholds HELP based on your reduced taxable salary, so you can be left with a repayment shortfall as a tax bill at return time. Budget for it.
• Division 293. Above $250,000 combined income, concessional contributions attract an extra 15% tax (30% total). Still typically better than the top marginal rate, but the saving halves.

How to Set It Up With Payroll

1. Check your headroom: $30,000 minus your expected SG (salary × 12%), minus any carry-forward you plan to use.
2. Ask payroll or HR for their salary sacrifice form or portal. The arrangement must be prospective — it can only apply to salary you haven't yet earned, so it starts from a future pay cycle.
3. Put it in writing: a simple agreement stating the amount per pay and the fund it goes to. Confirm your SG will still be calculated on your full pre-sacrifice salary (this is a legal requirement since 2020, but it's worth the one-line email).
4. Verify the first cycles: check your payslip shows the deduction as "RESC"/salary sacrifice super and that it arrives in your fund.
5. Review each July when the new financial year resets your cap, and pause it if your circumstances change — most employers let you vary or stop with a pay cycle's notice.

First Home Super Saver Scheme (FHSS)

Eligible first home buyers can withdraw voluntary contributions (up to $15,000 per year, $50,000 in total, plus deemed earnings) toward a first home deposit. Sacrificed contributions get the concessional treatment going in, and the withdrawal is taxed at your marginal rate less a 30% offset — usually a meaningful net saving versus a bank account. Only voluntary contributions qualify (never SG), and you must request an FHSS determination from the ATO before signing a contract.

Frequently Asked Questions

Does salary sacrifice reduce my employer's super contributions?

It shouldn't. Since 1 January 2020, employers must calculate SG on your pre-sacrifice ordinary time earnings, and sacrificed amounts can't count toward the SG they owe. Confirm with payroll that your 12% is based on your full salary.

Is salary sacrifice better than a personal deductible contribution?

The net tax result is identical. Salary sacrifice wins on automation and discipline; personal deductible contributions win on flexibility and timing — but require the notice-of-intent paperwork to be lodged and acknowledged before you claim the deduction.

How much can I salary sacrifice in 2026?

Up to the $30,000 concessional cap minus your employer's SG. On $95,000, that's roughly $18,600 of headroom; check your carry-forward balance in myGov if your super balance is under $500,000, as it may allow considerably more.

Does salary sacrifice affect my HECS-HELP repayments?

Yes — repayment income adds reportable super contributions back, so sacrificing doesn't lower your compulsory repayment and can create a shortfall bill at tax time because payroll withholds less.

When can I access the money?

Generally at preservation age 60 once you retire (or via transition-to-retirement rules), with the FHSS scheme the main earlier exception for eligible first home buyers.

Can I change or stop the arrangement?

Yes. Salary sacrifice isn't locked in — you can vary or cancel it with your employer at any time, effective from a future pay cycle.
