Tax on the same dollar of pre-tax income

Pre-tax super contributions are taxed at 15% rather than your marginal rate: the core tax-effectiveness argument.

Tax-effective use of super
You're saving $1,800 in tax this year by contributing pre-tax to super (vs paying 30% marginal rate).

How it works

Super is taxed when money goes in, while it earns, and sometimes when it comes out, and the rates depend on your age, your income and the kind of contribution. This works out the tax at each stage on your numbers, and how it compares with paying your marginal rate.

  1. 1Enter your total annual income to determine your marginal tax rate.
  2. 2Input your employer super contributions (SG amount).
  3. 3Add any salary sacrifice or personal after-tax contributions.
  4. 4Enter your current balance and expected return rate.
  5. 5See a breakdown of tax on contributions, earnings, and eventual withdrawal.

The figures today

Across 50 MySuper products, the typical return over the ten years to 30 June 2026 was 8.0% a year after fees and tax, and the typical fee on a $50,000 balance was $408 a year, from APRA's data.

Worked examples

Tax Savings from Salary Sacrifice

Sarah earns $120,000 and salary sacrifices $10,000 into super.

Without salary sacrifice, Sarah pays 32% (marginal rate + Medicare) on that $10,000 = $3,200 tax. In super, the tax is 15% = $1,500. Net tax saving: $1,700 per year. Over 25 years with compounding, this strategy adds ~$100,000+ to her super.

Division 293 Warning

James earns $260,000. His employer pays $31,200 in SG (12%).

James exceeds the $250,000 threshold for Division 293 tax. He'll pay an additional 15% (total 30%) on the portion of contributions that push him over the threshold. He should consider this when planning additional salary sacrifice.

Questions people ask

What is Division 293 tax?
Division 293 imposes an additional 15% tax on super contributions for individuals whose income plus concessional contributions exceed $250,000. This brings the total tax on those contributions to 30% instead of 15%. The ATO will send you an assessment after you lodge your tax return.
Are super withdrawals taxed?
For most people withdrawing after age 60 from a taxed fund, withdrawals are completely tax-free. Before age 60, withdrawals may be taxed depending on the tax components. Lump sum withdrawals of the tax-free component are always tax-free regardless of age.
Can I claim a tax deduction for personal super contributions?
Yes. If you make personal contributions to your super fund, you can claim a tax deduction by lodging a 'Notice of Intent to Claim a Deduction' with your fund before lodging your tax return. This effectively converts non-concessional contributions to concessional contributions.

The terms, in plain English

Concessional Contributions
Pre-tax contributions including employer SG, salary sacrifice, and personal contributions you claim a tax deduction for. Taxed at 15% entering the fund (cap: $32,500/year).
Non-Concessional Contributions
After-tax contributions made from your take-home pay. Not taxed entering the fund because tax has already been paid (cap: $130,000/year).
Division 293
An additional 15% tax on super contributions for high-income earners whose income plus super contributions exceed $250,000.
Earnings Tax
Investment returns earned inside super are taxed at a maximum of 15%. Capital gains held for over 12 months are taxed at 10% (one-third discount).
