Non-Concessional Super Contributions 2025: Rules, Limits & Strategies

Want to boost your super and pay less tax in retirement? Non-concessional contributions might be your secret weapon. With new rules and higher caps coming into effect in 2025, now’s the time to take a fresh look at how after-tax super contributions can fit into your financial plan.

What Are Non-Concessional Super Contributions?

Non-concessional contributions are after-tax amounts you add to your super fund. Unlike concessional (pre-tax) contributions, these don’t attract a 15% contributions tax on entry, because you’ve already paid tax on the money. They’re a popular way for Australians to fast-track their super savings, particularly for those close to retirement or selling assets like an investment property.

In 2025, non-concessional contributions remain a central part of superannuation strategy, especially in a rising-cost environment and with the government’s ongoing tweaks to super rules.

2025 Non-Concessional Contribution Caps & Rules

The government reviews super caps regularly to keep up with inflation and wage growth. Here’s what you need to know for 2025:

• Annual cap: The non-concessional contributions cap for 2025 has increased to $120,000 per financial year (up from $110,000 in 2024).
• Bring-forward rule: If you’re under 75, you can trigger the bring-forward arrangement and contribute up to $360,000 in a single financial year by ‘bringing forward’ three years’ worth of caps.
• Total super balance: You can only make non-concessional contributions if your total super balance is below $1.9 million as at 30 June of the previous financial year. If you’re over this threshold, you can’t make further non-concessional contributions without penalty.
• Age limits: The work test was scrapped for non-concessional contributions up to age 75. This means even if you’re retired, you can still contribute up until just before you turn 75.

Example: Kim, aged 62, has a super balance of $1.3 million. In July 2025, she sells an investment property and decides to top up her super. She can contribute $360,000 at once (using the bring-forward rule), provided she hasn’t triggered it in the past two years and her balance remains under $1.9 million.

Why Consider Non-Concessional Contributions?

With superannuation earnings taxed at just 15% (and 0% in pension phase), moving your after-tax savings into super can deliver huge long-term benefits. Here’s why more Australians are making these contributions in 2025:

• Tax-free withdrawals: Once you reach preservation age and retire, withdrawals of both your contributions and earnings are tax-free.
• Boost your retirement: Higher balances mean more income in retirement, especially with the Age Pension asset test tightening in 2025.
• Estate planning: Non-concessional contributions can be a way to pass wealth to beneficiaries, as the tax on death benefits is lower for non-concessional amounts.

With property and share markets fluctuating, using non-concessional contributions can also help diversify your wealth into the tax-advantaged super environment.

Key Strategies and Pitfalls in 2025

Non-concessional contributions are powerful, but there are traps and opportunities to navigate:

• Timing: Plan contributions early in the financial year to avoid missing out if your super balance rises above the cap by June 30.
• Downsizer contributions: In 2025, Australians aged 55+ can also access the downsizer contribution (up to $300,000 per person from the sale of a home). This is separate from the non-concessional cap and can be combined for a mega-boost to super.
• Excess contributions: Exceed the cap and you’ll pay extra tax and could see your excess contributions taxed at the top marginal rate.
• Splitting with your spouse: Consider spouse splitting to balance super between partners and optimise tax and Centrelink outcomes.

Real-world scenario: Raj and Priya, both 60, sell their family home in Melbourne. Each makes a $300,000 downsizer contribution and uses the bring-forward rule for $360,000 in non-concessional contributions. In one year, they add $1.32 million to their combined super—tax-free and ready for retirement.

Recent Policy Updates and What’s Next

In 2025, the government reaffirmed its commitment to preserving the superannuation system’s integrity, but also raised the non-concessional cap in line with average wage growth. There are ongoing discussions about further indexation, and possible changes to total super balance thresholds as the population ages. Expect more tweaks in the federal budget cycles, but the core benefits of non-concessional contributions remain intact for now.

Conclusion: Make Your Super Work Harder

Non-concessional super contributions are more than just a tax perk—they’re a strategic lever for Australians to take control of their financial future. With the 2025 cap increases and policy tweaks, there’s never been a better time to review your super strategy, especially if you’re approaching retirement or have a windfall to invest. The earlier you act, the more you could benefit from compounding growth and tax-free retirement income.
