Is Salary Sacrificing Into Super Worth It?
The short answer: if you earn over $45,000 and can afford a small reduction in take-home pay, yes — it's one of the most tax-effective strategies available to Australian workers. Here's exactly how it works with real numbers.
How It Works
Instead of receiving part of your salary as cash (taxed at your marginal rate — up to 45%), you redirect it into super where it's taxed at only 15%. The difference is your tax saving. Your employer's 12% super guarantee contributions don't change — salary sacrifice is on top of that.
The Real Numbers
$60,000 salary, sacrificing $5,000/year: Your marginal rate is 30%. Tax on $5,000 normally: $1,500. Tax on $5,000 in super: $750. You save $750 in tax while adding $4,250 (after 15% tax) to your super. Your take-home pay drops by $3,500 — but your total wealth increases by $750. Net benefit: $750/year.
$90,000 salary, sacrificing $10,000/year: Marginal rate: 30%. Tax saving: $1,500/year. Super receives $8,500 (after 15% tax). Take-home drops by $7,000. Net wealth increase: $1,500/year.
$130,000 salary, sacrificing $15,000/year: Marginal rate: 37%. Tax saving: $3,300/year. Super receives $12,750. Take-home drops by $9,450. Net wealth increase: $3,300/year — and your super is growing significantly faster.
The $30,000 Cap
Total concessional contributions (employer SG + salary sacrifice) are capped at $30,000/year. On a $90,000 salary, your employer contributes $10,800 (12%), leaving room for $19,200 in salary sacrifice before hitting the cap. Exceed the cap and the excess is taxed at your marginal rate plus a charge — worse than not salary sacrificing at all.
Calculate Your Salary Sacrifice Benefit →When It's NOT Worth It
If your salary is under $45,000, your marginal rate is only 16% — the saving (16% minus 15% = 1%) is negligible. If you have high-interest debt (credit cards at 20%+), paying that off delivers a guaranteed 20% return versus 1-15% from salary sacrifice. If you need every dollar of take-home pay to cover expenses, reducing it further creates financial stress. Pay yourself first, but don't starve yourself.
For everyone else — particularly anyone earning $80,000+ with no high-interest debt — salary sacrifice is free money. The earlier you start, the more compound growth does the heavy lifting.
