How superannuation works in Australia

Superannuation — or "super" — is Australia's compulsory retirement savings system. It's one of the most powerful wealth-building tools available to Australian workers, but the rules can be confusing. Here's what you need to know to make sense of your super and project where you'll land at retirement.

How it works

Your employer is legally required to contribute a percentage of your ordinary time earnings into a super fund on your behalf. This is called the Superannuation Guarantee (SG). From 1 July 2025, the SG rate rose to 12% — its final legislated rate after a decade of gradual increases from 9.5%.

That 12% lands in your super account and is invested by your fund across a mix of assets — shares, property, bonds, and infrastructure — depending on the investment option you choose. Over time, compound returns do the heavy lifting. A dollar invested at age 30 can be worth $7–10 by the time you retire at 65, assuming a 7.5% annual return.

You can accelerate this by making extra contributions yourself. Salary sacrifice — where you ask your employer to direct some of your pre-tax pay into super — is taxed at just 15%, compared to your marginal tax rate which could be 30% or higher. This is one of the most effective (and legal) ways to reduce tax while boosting your retirement savings.

Australian context

Australia's super system is unique. The total pool of super assets exceeds $3.9 trillion, making it one of the largest pension systems in the world relative to GDP. Key rules to know:

• Preservation age: You can access your super from age 60 (if you retire) or 65 regardless of employment. Born after June 1964? Your preservation age is 60.
• Concessional contributions cap: $30,000 per year (2025–26). This includes your employer's SG and any salary sacrifice. Go over and you'll pay extra tax.
• Carry-forward rule: If your total super balance is under $500,000, you can use unused concessional cap amounts from the previous 5 years — a great catch-up strategy.
• Government co-contribution: If you earn under $60,400 and make a personal after-tax contribution, the government may match up to $500.

Common mistakes

• Ignoring fees: A 1% difference in fees can cost you $100,000+ over your career. Compare funds on performance after fees.
• Default investment option: The default "balanced" option may not suit you. If you're under 40, a growth or high-growth option might be more appropriate.
• Multiple accounts: If you've changed jobs, you might have 2–3 super accounts all charging fees. Consolidate into one low-fee fund via MyGov.
• Assuming 12% is enough: For most people, the SG alone won't deliver a comfortable retirement. Even an extra 2–3% salary sacrifice makes a huge difference over 30 years.
• Relying on the Age Pension alone: The full Age Pension is about $29,000/yr for a single. It's a safety net, not a retirement plan.
