How salary sacrifice saves tax

You agree with your employer to take less salary and have the difference paid into super before tax ever touches it. Sacrifice $10,000 from a $100,000 salary and your taxable income drops to $90,000: tax and Medicare fall by $3,200, take-home pay falls by $6,800, and $8,500 lands in your fund after the 15% contributions tax. Giving up $6,800 of spending money to bank $8,500 is the whole pitch in one sentence. This tool sits alongside the rest of our tax calculators if you want the full pay picture.

The saving scales with your marginal rate under the 2026-27 tax brackets. The same $10,000 sacrifice saves $3,200 in the 30% bracket but $4,700 in the top bracket, because the sacrificed dollars would otherwise have been taxed at 45% plus the Medicare levy. In the 15% bracket the arithmetic barely moves: the fund pays 15% anyway, so the arrangement earns its keep from the 30% bracket up.

Salary packaging vs salary sacrifice

The two terms get used interchangeably, but packaging is the umbrella. Salary packaging means paying for anything out of pre-tax salary: super, cars, laptops, or living expenses if you work for a charity or public hospital. Salary sacrificing to super is the specific arrangement this page calculates, and it is the simplest of the lot because super has its own flat 15% contributions tax.

Packaged cars and other benefits work differently: they can attract fringe benefits tax through your employer and show up on your income statement as reportable fringe benefits. If a car is the benefit you are weighing up, the novated lease tax calculator models that pre-tax deduction instead.

Watch-outs before you sign the form

Worth checking first

  • The $32,500 concessional cap for 2026-27 counts employer SG plus your sacrifice together
  • Confirm with payroll that your 12% SG stays based on your pre-sacrifice salary
  • Sacrifice agreements only work on future salary, so set them up before the pay period starts

What sacrifice does not do

  • It does not cut your HELP repayment: sacrificed super is added back to repayment income
  • It does not give you access to the money; super stays locked away until a condition of release
  • It does not escape tax entirely; the fund still deducts 15% on the way in

The HELP add-back trips people up every year. If you carry a study loan, run your pre-sacrifice income through the HECS repayment calculator to see the repayment that still applies. To estimate the employer SG side of your cap, use the super guarantee calculator.

Frequently asked questions

Does salary sacrifice reduce taxable income?
Yes. The sacrificed amount comes out before tax, so a $100,000 earner sacrificing $10,000 is taxed on $90,000 and saves $3,200 in tax and Medicare for 2026-27. The trade is that take-home pay falls by $6,800.
How much can I salary sacrifice into super?
The concessional cap for 2026-27 is $32,500, and it includes your employer's 12% SG as well as your sacrifice. If you have unused cap amounts from earlier years you may be able to carry them forward; your fund or ATO online services shows the running total.
Is salary sacrificing worth it on my income?
The saving per dollar equals your marginal rate minus the 15% contributions tax. In the 30% bracket that is a solid gap; in the top bracket the same $10,000 saves $4,700. In the 15% bracket the gap nearly vanishes, so check the numbers before locking money away.
Does salary sacrifice reduce my HECS repayment?
No. Sacrificed super counts as a reportable super contribution, which the ATO adds straight back into your repayment income. Your HELP repayment is worked out as if you never sacrificed.
What is the 15% contributions tax?
Concessional contributions, including salary sacrifice and employer SG, are taxed at 15% inside the super fund rather than at your marginal rate. That gap between 15% and your bracket is the entire source of the saving.
What happens if I go over the concessional cap?
Excess concessional contributions are taxed at your marginal rate less a 15% offset for the tax the fund already paid, which unwinds the benefit. The ATO tracks the cap across all your funds and will issue a determination if you exceed it.
Salary packaging and salary sacrifice: same thing?
Sacrifice to super is one form of packaging. Packaging covers any benefit paid from pre-tax salary, including cars and devices, some of which trigger fringe benefits tax. Super is the clean case with its own 15% treatment.
