Catch-Up Super Contributions: Making the Most of Your Final Years

The Window Is Open But Not Forever.

There’s a version of this story that plays out regularly.

Someone hits their mid-50s, finally starts taking retirement planning seriously, and realises their super isn’t where it needs to be. Maybe they took time out of the workforce. Maybe they were self-employed and contributions were sporadic. Maybe they just never got around to salary sacrificing consistently because life kept getting in the way.

The question is always the same: is it too late to fix it?

Not necessarily. The catch-up contribution rules exist precisely for this situation. And for many Inner West professionals in their 50s and early 60s, they’re one of the most powerful tools available for accelerating super in the final stretch before retirement.

But they’re time-limited. And they require your super balance to be under a specific threshold to use them. Which means the window for some people is narrower than they think.

The Basics: Concessional Contribution Caps

Let’s start with the foundation.

Concessional contributions are before-tax contributions to super — employer contributions (including compulsory super), salary sacrifice amounts, and personal contributions you claim as a tax deduction.

The annual concessional cap is currently $30,000 per financial year (2025–26). Any amount contributed above this cap is included in your assessable income and taxed at your marginal rate — with a 15% offset.

For most working Australians, employer SG contributions eat up a chunk of this cap. On a $100,000 salary, the 11.5% SG rate means roughly $11,500 in mandatory employer contributions — leaving around $18,500 in headroom to salary sacrifice or contribute personally.

Many people never use that headroom. Which is where catch-up contributions come in.

Catch-Up Contributions: How They Work

If your total super balance was under $500,000 on 30 June of the previous financial year, you can carry forward any unused concessional cap from the previous five financial years — and use it in a single year.

To illustrate how this works:

Suppose you’re 58, your super balance is $420,000, and for the past three years you’ve only had employer SG contributions going in — say $11,000 per year, leaving about $19,000 unused each year.

Over three years, that’s up to $57,000 in carried-forward cap. In a year where you have the cash available — from a bonus, a redundancy, an inheritance, or proceeds from an investment sale — you could potentially contribute significantly more than the standard $30,000 cap, all at the concessional tax rate of 15%.

The tax saving compared to taking that income at your marginal rate can be substantial. On a 39% marginal rate (including Medicare), the difference is 24 cents in the dollar. On $50,000, that’s $12,000 in tax you didn’t pay.

The $500,000 Balance Threshold

The catch-up rules are means-tested in a specific way. Your total super balance — across all your funds — must be below $500,000 on 30 June of the previous year for you to access carried-forward amounts.

This is worth checking carefully. If your super balance is already close to or above $500,000, the catch-up mechanism isn’t available to you.

For many Inner West pre-retirees, this means acting sooner rather than later. If your balance is currently $380,000 and growing, the window for catch-up contributions may be narrower than you’d expect. Plan when to use the carried-forward cap before the balance threshold closes off the option.

Non-Concessional Contributions: The After-Tax Option

Catch-up rules apply to concessional (before-tax) contributions. But there’s a separate mechanism for after-tax contributions worth knowing about.

Non-concessional contributions (NCCs) are made from your after-tax income — money you’ve already paid tax on. The annual NCC cap is $120,000 (2025–26), but if you’re under 75 you can use the ‘bring-forward’ rule to contribute up to three years’ worth in a single year — up to $360,000.

This is relevant if you have a lump sum outside super — from a property sale, an inheritance, or a windfall — and you want to move it into the tax-effective super environment before retirement.

There’s a separate total super balance threshold for NCCs. Once your super balance exceeds $1.9 million, non-concessional contributions are not permitted. For the bring-forward rule, partial eligibility applies between $1.66 million and $1.9 million.

The Downsizer Contribution: A Separate Mechanism

If you’re 55 or older and you sell a home you’ve owned for at least 10 years, you may be able to make a downsizer contribution of up to $300,000 per person ($600,000 per couple) into super — outside the normal contribution caps.

This applies even if you have more than $500,000 in super. It’s not subject to the total super balance threshold for NCC purposes (though it does count toward your transfer balance cap once in pension phase).

The downsizer contribution is one of the most significant mechanisms available to Inner West pre-retirees, given the property values in our area. A couple selling a Balmain terrace could potentially inject $600,000 into super from the proceeds — significantly boosting their dairy herd for retirement.

It requires careful planning — you need to make the contribution within 90 days of settlement, and it has implications for your Age Pension assessment — but for the right client, it’s transformative.

Strategies Worth Considering

Here’s how these mechanisms typically come together for Inner West clients in their 50s and early 60s:

• Salary sacrifice aggressively in your final working years to maximise concessional contributions and reduce taxable income
• Review your carried-forward concessional cap balance — most super funds will show this in your account details or it can be checked via your MyGov/ATO account
• Time a large concessional contribution in a year where your income is higher than usual — a bonus year, a trust distribution, or a year before you step back to part-time
• Use a downsizer contribution if you’re planning to sell the family home and downsize as part of your retirement transition
• Consider a spouse contribution or contribution splitting if one partner has a lower super balance — equalising balances can be tax-effective

Why This Connects to Building Your Dairy Herd

Maximising super contributions in your final working years is the most direct way to expand your dairy herd — and that’s the foundation of the 2 Cows Strategy.

Every extra dollar in super — particularly in the final five to ten years — has more impact than it looks. You’re not just adding to the balance; you’re adding income-producing capacity. If your super earns 5% in distributions per year, an extra $50,000 in contributions adds $2,500 per year in income. Every year. For the rest of your retirement.

Getting the herd as large as possible before you retire — using every legitimate mechanism available — is what the final stretch of pre-retirement planning is about.

The catch-up rules are one of the best tools available to do exactly that. But they’re time-limited, income-dependent, and balance-threshold restricted. The earlier you look at them, the more options you have.
