What Is Superannuation?
Superannuation - usually just called "super" - is a system where money is set aside during your working life to fund your retirement. It's compulsory: your employer must pay a percentage of your ordinary time earnings into a super fund on your behalf. You generally can't touch this money until you retire.
The money sits in a super fund, gets invested (in shares, property, bonds, or cash depending on your chosen investment option), and compounds over your entire working life. The tax treatment is preferential - contributions and earnings inside super are taxed at lower rates than your personal income.
Australia's super system holds over $3.5 trillion in assets - it's one of the largest pension systems in the world relative to the size of the economy.
The Superannuation Guarantee rate is 11.5% for 2024/25 and rises to 12% from 1 July 2025. This means if you earn $80,000 per year, your employer must contribute at least $9,200 to your super in 2024/25 - rising to $9,600 from July 2025. This is in addition to your salary, not taken from it (unless you're on a total remuneration package).
Types of Contributions
| Contribution Type | Tax Treatment | 2024/25 Cap | Who Makes It |
|---|---|---|---|
| Employer SG | Taxed at 15% in fund | Part of $30k cap | Your employer |
| Salary sacrifice | Taxed at 15% in fund | Part of $30k cap | You (pre-tax) |
| Personal deductible | Taxed at 15% in fund | Part of $30k cap | You (claim deduction) |
| Non-concessional (after-tax) | No tax on entry | $120,000/yr | You (no deduction) |
| Government co-contribution | Tax-free | Up to $500 | Government (if eligible) |
| Spouse contribution | Tax offset available | Within NCC cap | Your spouse |
The concessional cap of $30,000 covers all before-tax contributions combined - your employer's SG, any salary sacrifice you arrange, and any personal contributions you claim a tax deduction for. If your employer's SG alone is $11,500 on a $100,000 salary, you have $18,500 of remaining concessional cap to use through salary sacrifice or personal deductible contributions.
How Super Is Taxed
Super's tax treatment is what makes it so powerful for long-term wealth building. There are three stages:
- On contributions: Concessional (before-tax) contributions are taxed at 15% inside the fund. If your marginal tax rate is 32.5% or 37%, contributing to super saves you the difference in tax. High earners above $250,000 pay an extra 15% (Division 293 tax), making their effective super tax rate 30% - still lower than the top marginal rate of 45%
- On earnings: Investment earnings inside super are taxed at a maximum of 15%. Capital gains on assets held for more than 12 months are taxed at an effective rate of 10% (a one-third discount applies). Compare this to paying your marginal rate of up to 47% on investment income outside super
- On withdrawal: Once you reach age 60 and meet a condition of release, super withdrawals are generally completely tax-free - both lump sums and pension income payments
Salary Sacrifice - The Most Accessible Strategy
Salary sacrifice means asking your employer to redirect part of your pre-tax salary into super rather than paying it to you as income. You pay 15% tax on that money inside super instead of your marginal rate.
On a salary of $90,000 (marginal rate 32.5%), sacrificing $10,000 per year into super:
- Without salary sacrifice: $10,000 is taxed at 32.5% = $3,250 in tax, leaving $6,750 after tax
- With salary sacrifice: $10,000 goes into super, taxed at 15% = $1,500 in tax, leaving $8,500 in super
- Annual saving: $1,750 - plus the compounding of that extra $1,750 over decades
You set this up through your employer's payroll department. Most employers accommodate this. The only constraint is staying within the $30,000 concessional cap including your employer's SG.
Some employment contracts are structured as "total remuneration" packages where super is included in the stated salary figure. If that's your situation, salary sacrifice reduces your take-home pay dollar for dollar and the benefit calculation is different. Check your contract or ask HR before assuming your employer's SG is on top of your salary.
When Can You Access Your Super?
Super is preserved until you meet a condition of release. The main one is reaching your preservation age and retiring. Preservation age depends on your date of birth:
- Born before 1 July 1960: preservation age is 55
- Born 1960-1964: preservation age rises gradually from 56 to 59
- Born on or after 1 July 1964: preservation age is 60
Once you reach 65, you can access your super regardless of whether you've retired. Other conditions of release include permanent incapacity, terminal illness, severe financial hardship (limited access), and the First Home Super Saver Scheme for first home buyers.
Choosing a Super Fund
Check fees first
Annual fees of 1% vs 0.5% on a $200,000 balance cost $1,000 vs $500 per year. Over 20 years compounded, that's a difference of tens of thousands. Use the ATO's YourSuper comparison tool to compare fees across funds.
Check long-term performance
Compare 5 and 10-year net returns (after fees and tax). The ATO's YourSuper tool shows this. Avoid comparing short-term returns - one good year means nothing.
Consolidate multiple accounts
Each super account charges fees. If you've changed jobs, you may have multiple accounts. Consolidate into one through myGov/ATO online - it takes minutes and saves you paying multiple sets of fees.
Choose the right investment option
Most funds default you to a "balanced" option. If you're under 50, a higher growth option (more shares, less bonds) typically produces better long-term returns. Review your investment option every few years as you approach retirement.
If you earn under $58,445 (2024/25) and make after-tax contributions to super, the government adds a co-contribution of up to $500. To get the maximum $500 co-contribution, earn under $43,445 and contribute $1,000 after-tax. The co-contribution phases out between $43,445 and $58,445. This is genuinely free money - check if you're eligible.
