How superannuation contributions work
Superannuation is Australia's compulsory retirement savings system. Your employer contributes a percentage of your salary (the Superannuation Guarantee) into your super fund, where it grows until you retire.
Types of super contributions
Concessional contributions
Before-tax contributions including:
- Employer SG contributions (mandatory 12%)
- Salary sacrifice (voluntary pre-tax)
- Personal deductible contributions
Taxed at 15% inside super. Cap: $30,000/year
Non-concessional contributions
After-tax contributions including:
- Personal contributions (no tax deduction claimed)
- Spouse contributions
- Government co-contributions
Not taxed (already taxed). Cap: $120,000/year
Superannuation Guarantee rate history
| Financial Year | SG Rate |
|---|---|
| 2023-24 | 11% |
| 2024-25 | 11.5% |
| 2025-26+ | 12% (final rate) |
Salary sacrifice benefits
Salary sacrificing into super can be one of the most tax-effective ways to build wealth. By contributing pre-tax dollars, you pay only 15% contributions tax instead of your marginal income tax rate.
| Your Marginal Rate | Super Tax Rate | Tax Saved per $1,000 |
|---|---|---|
| 16% ($18,201 - $45,000) | 15% | $10 |
| 30% ($45,001 - $135,000) | 15% | $150 |
| 37% ($135,001 - $190,000) | 15% | $220 |
| 45% ($190,001+) | 15% | $300 |

Division 293 tax for high earners
If your income plus concessional super contributions exceeds $250,000, you pay an additional 15% tax on your super contributions. This brings the total tax on affected contributions to 30%.
How Division 293 is calculated
- Add your taxable income plus concessional super contributions
- If the total exceeds $250,000, Division 293 applies
- The additional 15% tax applies to the lesser of:
- Your concessional contributions, or
- The amount by which you exceed $250,000
Example: Division 293 calculation
Income: $240,000
Super contributions: $25,000 (SG + salary sacrifice)
Div 293 income: $265,000
Amount over threshold: $15,000
Div 293 tax: $15,000 x 15% = $2,250
The $2,250 is in addition to the $3,750 (15%) already deducted from contributions.
Concessional cap and carry-forward
The concessional contributions cap for 2025-26 is $30,000 per year. This includes all employer SG, salary sacrifice, and personal deductible contributions.
Carry-forward unused caps
If your total super balance is under $500,000, you can carry forward unused concessional cap amounts from the previous 5 years. This allows for larger contributions in years when you have extra income.
Example: If you only used $20,000 of your cap last year, you have $10,000 unused. This year you could contribute up to $40,000 ($30,000 + $10,000 carry-forward).
