Feel like your super balance isn't quite where it should be? There's a powerful rule called carry-forward concessional contributions that lets you play catch-up by using the 'unspent' portions of your pre-tax contribution caps from previous years.
It’s a bit like rolling over unused mobile data. If you didn't use your full allowance one month, you get to add it to the next. The same principle applies here, allowing you to make larger, tax-effective contributions to boost your retirement savings. This is a key strategy we implement for clients at Wealth Collective to help them accelerate their journey to financial freedom.
Catch Up on Your Super with Carry-Forward Contributions
It’s easy to get so caught up in building a career or a business that your retirement savings take a backseat. Years can fly by, and suddenly you realise your super hasn't kept pace with your ambitions. If that sounds familiar, you're not alone. This is a common story for driven professionals, business owners, and anyone juggling life's financial priorities.
The good news? The system has a built-in, though often overlooked, mechanism to help you make up for lost time without being penalised.
Supercharge Your Retirement Savings
This strategy is known as making carry-forward concessional contributions. In simple terms, it lets you use any leftover concessional (pre-tax) contribution caps from the past five financial years. This is a game-changer for:
- High-income earners who want to reduce their taxable income.
- Business owners or contractors with lumpy or unpredictable income streams.
- Anyone returning to the workforce after a break who needs to get their super back on track.
Let’s say you're an executive in Perth, so focused on your work that you haven't been maxing out your super contributions. Thanks to this rule, which kicked in from the 2018-19 financial year, you can now bundle up all that unused cap space and make a significant contribution in a single year.
This is your clear, step-by-step roadmap to understanding how you can accelerate your journey towards a secure retirement. It transforms a complex rule into a practical wealth-building tool.
This guide will break down exactly how it works, who can use it, and how to figure out your available cap. We'll walk through real-world examples to make it all crystal clear, giving you the confidence to take the next step. If you need a refresher on the basics, our guide on what superannuation is in Australia is a great place to start.
Putting this rule into action is a cornerstone of our Retirement Roadmap service. At Wealth Collective, we specialise in helping clients turn this opportunity into a tangible financial outcome, ensuring their strategy is perfectly aligned with their long-term goals. Let's dive in and see how you can make it work for you.
How the Carry Forward Contribution Rule Works
First, let's quickly recap what a concessional contribution is. In simple terms, it's any 'before-tax' money that goes into your super fund. This covers the super your boss pays for you (Superannuation Guarantee) and any extra you chip in through a salary sacrifice arrangement.
Every year, there's a strict limit on these contributions, known as the concessional cap. The carry-forward rule is a fantastic provision that lets you mop up any leftover, unused parts of this cap from previous years. It's designed to help people catch up on their super, especially if they’ve had periods of lower income, taken time off work, or were self-employed.
The Two Golden Rules of Eligibility
So, who gets to use this strategy? It's not available to everyone, and the Australian Taxation Office (ATO) has two clear conditions you must meet. Getting this right is critical, as failing to meet either one means you can't use the rule for that financial year.
The main hurdle is your super balance. To be eligible, your total super balance must have been less than $500,000 on the 30th of June of the previous financial year. This is a non-negotiable threshold and the most common reason people find they aren't eligible.
The second condition is much simpler: you actually need to have unused concessional cap amounts from the last five years. If you’ve been a diligent saver and have hit your cap every single year, you won't have anything left over to carry forward.
To help you figure out where you stand, we've put together a simple checklist.
Quick Eligibility Check for Carry Forward Contributions
Use this simple checklist to see if you could be eligible to use the carry-forward rule in the current financial year.
| Eligibility Factor | What You Need to Check |
|---|---|
| Total Super Balance | Was your total super balance under $500,000 on 30 June of last year? You can find this figure on your latest super statement or through ATO online services via myGov. |
| Unused Caps | Do you have unused concessional contribution cap amounts from any of the past five financial years (starting from 2018–19)? This information is also available in your myGov account. |
If you can tick both these boxes, you're likely in a position to take advantage of this powerful strategy.
At Wealth Collective, our initial analysis always starts with these two key eligibility checks. It’s the foundational step in our Retirement Roadmap service to ensure any super-boosting strategy is both compliant and effective for your specific situation.
Understanding the Five-Year Rolling Window
The system works on a ‘five-year rolling window’. This means you can only reach back and use the unused caps from the last five financial years. Once a year drops off the back of that window, any unused amount from that year is gone for good.
For example, when we enter the 2025–26 financial year, any unused cap you had from the 2019–20 financial year will vanish forever if you haven't used it. This "use it or lose it" nature means a bit of forward planning is essential.
The good news is the ATO automatically applies your contributions against your oldest available unused cap first. This is a huge help, as it ensures the amounts closest to expiring are used up before they disappear, helping you get the maximum benefit.
While the ATO tracks all this for you, just having the data isn't the full picture. The real art is knowing when to use your accumulated cap. A Wealth Collective adviser can help you pinpoint the best time to make a larger contribution—perhaps to offset a capital gain from selling an asset or to minimise your tax bill in a high-income year.

How to Calculate Your Available Carry-Forward Cap
Alright, let's get down to the numbers. Knowing the rules is one thing, but figuring out your exact contribution room is where the real power lies. To do this, you'll need to look back at the last five financial years and add up any unused portions of your concessional caps.
Think of it like checking for unused credits on your account. Each year you contributed less than the limit, you banked a little extra capacity. Now, you can add up those credits to see how much you can contribute above this year's standard cap.
A Step-by-Step Calculation Example
Let's walk through a realistic scenario. Imagine Sarah, whose income has fluctuated a bit over the years. Importantly, her total super balance has always been comfortably under the $500,000 threshold.
Here’s a breakdown of her contributions against the annual caps:
- 2021–22 Financial Year: The cap was $27,500. Sarah put in $20,000, leaving $7,500 unused.
- 2022–23 Financial Year: The cap was $27,500. Sarah contributed $22,000, leaving $5,500 unused.
- 2023–24 Financial Year: The cap was $27,500. Sarah added $25,000, leaving $2,500 unused.
- 2024–25 Financial Year: The cap increased to $30,000. Sarah put in $25,000, leaving $5,000 unused.
- 2025–26 Financial Year: The cap is $30,000. Sarah contributes $28,000, leaving $2,000 unused.
To work out her total carry-forward amount for the 2026–27 financial year, we just add up all those unused bits: $7,500 + $5,500 + $2,500 + $5,000 + $2,000 = $22,500.
This means in the 2026–27 financial year, Sarah can contribute the standard $30,000 cap plus her extra $22,500. That's a total potential tax-deductible contribution of $52,500.
The diagram below shows the simple checks you need to make before you even start calculating.
It’s a great reminder: always check your Total Super Balance first, then find your unused amounts. Get those two things right, and you're on your way.
How Your Contributions Are Applied
Here’s a smart detail in the rules you need to know: the Australian Taxation Office (ATO) automatically applies your catch-up contributions against your oldest available unused cap first. This is a fantastic feature.
It means the amounts closest to expiring (remember that five-year rolling window?) get used up before they disappear. You don't have to do a thing.
In Sarah’s case, when she makes her catch-up contribution in 2026–27, the ATO will first use the $7,500 she had left over from the 2021–22 financial year. This system is designed to give you the maximum long-term benefit without any complicated admin.
The potential for a massive catch-up contribution is huge, especially for those who haven't maximised their caps. For instance, in the 2025–26 financial year (starting 1 July 2025), the concessional cap is $30,000. If your super balance was under $500,000 on 30 June 2025, you could access unused caps from as far back as 2020–21.
Imagine you made no concessional contributions for five years. You'd have banked $137,500 in unused caps. Add this year's $30,000, and you could theoretically make a tax-deductible contribution of $167,500 in one go! You can discover more insights about superannuation thresholds and see how they impact your broader strategy.
A word of caution: While you can find your unused cap information in your myGov account, relying on that figure alone can be risky. The data can sometimes lag and might not reflect very recent contributions.
The Importance of Professional Verification
This is precisely where professional advice makes all the difference. As part of our Retirement Roadmap service, we never take the ATO data at face value. A Wealth Collective adviser will meticulously cross-reference those figures with your actual contribution records to get the true picture.
Getting it wrong and accidentally contributing too much can trigger excess contributions tax and a whole lot of paperwork.
Our process ensures your strategy is solid, compliant, and timed perfectly to suit your financial situation—whether you want to reduce your tax bill in a high-income year or offset a large capital gain. It’s about turning a powerful rule into a precise, effective part of your wealth plan.

Strategic Scenarios for Using Carry-Forward Contributions
Knowing the rules of carry-forward contributions is one thing. Knowing exactly when to use them is where the real value lies.
A well-timed contribution can do more than just top up your super; it can dramatically reduce your tax bill and put your retirement savings on the fast track. It’s about turning a complex rule into a powerful tool for building wealth.
This is where our financial planning process shines. We look at your entire financial picture to pinpoint those key moments where a large, tax-deductible super contribution makes the most sense. Let's walk through a few real-world situations where this strategy is highly effective.
The Business Owner's Exceptional Year
Let's say you're a small business owner and you've just had a knockout year. Profits are way up, which is fantastic, but it also means you're staring down the barrel of a much bigger tax bill. This is a classic opportunity to put your unused caps to work.
By making a large personal deductible contribution, you can shift a decent chunk of that income from your top marginal tax rate—which could be as high as 47% with the Medicare levy—into the super environment, where it's taxed at only 15%. The tax saving can be enormous, and you've just given your nest egg a powerful boost.
Offsetting a Large Capital Gain
Another perfect time to use this strategy is after selling a major asset, like an investment property or a significant share portfolio. This kind of event almost always triggers a Capital Gains Tax (CGT) bill, which gets added to your taxable income for the year.
A smart carry-forward contribution can be a brilliant way to soften that blow. By using your banked contribution capacity, you can make a large deductible contribution that directly lowers your taxable income, reducing or even wiping out the CGT you owe. This is a core strategy we use with our Retirement Roadmap clients to protect their hard-earned investment returns from being lost to tax.
This forward-thinking approach is crucial. Instead of just reacting to a tax bill, you're proactively using the super system as intended to manage your financial outcomes across different areas of your life.
Returning to the Workforce
Life rarely moves in a straight line. Many of our clients take time out of the workforce to raise children, study, or care for a family member. During those years of lower or no income, super contributions often fall by the wayside, creating a savings gap that can feel hard to close.
This is where the carry-forward rule becomes your best friend. When you return to full-time work and start earning a higher income again, it allows you to catch up by contributing far more than the standard annual cap. It’s a fantastic way to get your retirement goals back on track much faster.
The Pre-Retirement Super Boost
As you get closer to retirement, your focus naturally shifts to beefing up your super balance to fund the lifestyle you’ve worked so hard for. This is often a time when your income is at its peak and major expenses, like the mortgage, are finally paid off, freeing up more cash.
If you’re in this phase of life, you might also find our guide on the transition to retirement strategy helpful.
For pre-retirees whose super balance is under the limit, using carry-forward contributions offers one last powerful opportunity to inject a large sum into their fund. That final boost before you hang up your boots can make a real difference to the income your super generates for the rest of your life.
Each of these scenarios shows how carry-forward concessional contributions are a tactical tool, not just a set-and-forget rule. At Wealth Collective, our job is to help you spot these opportunities on the horizon and build a plan to take full advantage of them, making sure you don’t leave valuable tax savings or retirement dollars on the table.
Watching Out for Traps and Tricky Rules
Using your carry-forward cap is a fantastic way to get more money into your super and potentially slash your tax bill, but it's not always a simple 'set and forget' strategy. Australian superannuation law is notoriously complex, and a few different rules can collide in unexpected ways. One wrong move could turn a savvy strategy into a costly headache, complete with penalty tax and a mountain of paperwork.
This is where getting the right advice is so important. It’s not just about knowing the rules; it’s about understanding how they all fit together and, crucially, how they apply to your specific financial situation.
The Division 293 Tax Sting
For high-income earners, the biggest trap is often Division 293 tax. This is an extra tax designed to level the playing field, reducing the tax concession on super contributions for anyone whose income and contributions combined tip over $250,000 in a financial year.
Let's say your income is already hovering near that $250,000 mark. Making a large catch-up contribution could easily push you over the threshold. If that happens, an additional 15% tax is slapped on some or all of your concessional contributions. Your contributions tax effectively doubles from 15% to 30%. Now, that's still likely better than your top marginal tax rate, but it’s a critical piece of the puzzle that can seriously change the numbers on your expected tax saving.
It’s exactly why our Retirement Roadmap service includes such a detailed tax analysis. We run the numbers on Division 293 before you make a move, so you know exactly what the net benefit will be, with no nasty surprises.
The Knock-On Effect on Other Contributions
Another area that needs a careful eye is how your pre-tax (concessional) contributions can impact your ability to make after-tax (non-concessional) contributions. It can be a real balancing act.
For example, making a large carry-forward contribution might, in some very specific scenarios, affect your eligibility to use other valuable strategies, like the bring-forward rule for non-concessional contributions. Get the timing or amounts slightly wrong, and you could unintentionally lock yourself out of another opportunity to build your nest egg.
At Wealth Collective, we see ourselves as your financial guardrail. We map out how all these rules interact to make sure one smart move doesn't accidentally trip up another, keeping your entire super strategy on track.
The High Cost of Getting it Wrong
The most common – and most expensive – mistake is simply putting in too much. This usually happens from a simple miscalculation of your unused caps or forgetting to add up all your contributions for the year, including what your employer puts in and any salary sacrifice you have set up.
The ATO is pretty good at tracking this and will automatically use your oldest available unused cap first. But if you go over your limit and have no carry-forward amount to cover it, you'll be hit with excess contributions tax. The extra amount is added back to your taxable income and taxed at your personal marginal rate (less a 15% tax offset), which completely wipes out the tax benefit you were hoping for. You can discover more key changes and implications for the latest super thresholds and how they apply.
With over 50 years of combined experience, our advisers at Wealth Collective will meticulously check your ATO records to confirm the exact carry-forward amounts you have available. From there, we build a clear plan that fits your goals, so you can build your super with confidence, not stress. Knowing what can go wrong is the first step to making sure it doesn't.
Taking the Next Step With Your Super
We’ve unpacked how powerful the carry-forward concessional contributions rule can be. It's a fantastic way to boost your retirement savings, trim your tax bill, and catch up if you’ve had years with lower contributions. But turning that knowledge into a real strategy takes careful planning tailored to your own financial life.
It's time to move from theory to action.
Turn a Smart Idea Into a Real Result
For people like small business owners with lumpy income or young professionals who've been smashing their mortgage, this strategy is a genuine game-changer. Why? Because contributions are taxed at just 15% inside super, which is a whole lot better than paying up to 45% (plus the Medicare levy) on your personal income. You can see more on how the various super thresholds impact your strategy and see key changes here.
Here at Wealth Collective, our advisers can pull up your ATO records to see exactly what your unused caps are and build a plan that fits perfectly into your bigger financial picture. This is a core part of our Retirement Roadmap service.
Getting super rules right comes down to the details. A simple miscalculation can flip a smart tax-saving move into a costly mistake, which is why having an expert double-check everything is so important.

Answering Your Questions
Getting your head around the details of carry-forward concessional contributions is the key to using this strategy with confidence. Let's tackle some of the most common questions that pop up.
What Happens If My Super Balance Goes Over $500,000 During the Year?
This is a great question and highlights a really important detail. Your eligibility is checked at a single point in time: the 30th of June of the previous financial year. That date is set in stone.
So, if your balance was under $500,000 on that specific day, you're good to go for the entire financial year that follows. It doesn't matter if investment returns or contributions later push your balance over the threshold during the year – your eligibility for that year is already locked in.
It all comes down to that one snapshot. This is something we double-check for clients as a crucial step in our Retirement Roadmap service to make sure everything is by the book.
Can I Use This Rule With a Self-Managed Super Fund?
Yes, you certainly can. The carry-forward rules are attached to you as an individual, not to the type of super fund you're with.
The rules of the game are the same for everyone, whether you have your money in a big industry fund, a retail fund, or you're running your own Self-Managed Super Fund (SMSF). You've got the same contribution caps, the same five-year rolling window to use up old amounts, and the same $500,000 balance test.
How Does Salary Sacrificing Affect My Carry-Forward Cap?
Salary sacrificing is a fantastic way to boost your super, and it's treated as a concessional contribution. This means any money you salary sacrifice counts towards your annual cap for that year.
Let’s say your employer’s compulsory super contributions plus your salary sacrifice payments don't quite use up your entire annual limit. The leftover amount simply becomes part of your ‘unused cap’ for that year, ready for you to catch up on later. You could then make a personal deductible contribution to use up that leftover amount from previous years.
Just remember that the five-year window is always ticking. From 1 July 2025, any unused cap amounts from the 2019–20 financial year will disappear for good. This makes the current 2024–25 financial year your last chance to use them. You can read more about how the latest superannuation thresholds have key changes and implications that might affect your plans.
