What if I exceed my super contribution caps?

Patrick McVeigh • August 24, 2021

Making additional personal contributions to superannuation is a great way to boost your retirement savings in a tax-effective way. But there are strict caps or limits on the amount you can contribute each year and stiff tax penalties for exceeding the limits.

Even though the annual contribution caps went up on 1 July 2021, you still need to keep a close eye on how much you and your employer contribute.

If you do go over your annual caps, it could be a costly mistake come tax time.

Higher limits from 1 July 2021
It’s important to remember there are caps on both the concessional (pre-tax) and non-concessional (after-tax) contributions you can make each year.

From 1 July 2021, the cap on concessional contributions into super is $27,500, regardless of your age. In recent years this annual cap was only $25,000, so the new higher limit means you can add a little more of your pre-tax income to your retirement nest-egg.

It’s worth remembering that your $27,500 concessional cap includes any contributions made into your account by your employer and any salary sacrifice amounts. Also, your employer’s compulsory super guarantee amounts increased from 9.5 per cent to 10 per cent from 1 July 2021, so you may need to be extra careful about exceeding your cap.

If your super account balance could do with a little help and you haven’t used the entire amount of your annual concessional contributions cap in recent years, you may be eligible to contribute a larger amount using the ‘carry-forward’ rule.

The annual cap on non-concessional (after-tax) contributions also rose on 1 July 2021 from $100,000 to $110,000.

If you meet certain eligibility criteria, you may be able to contribute up to three years of non-concessional contributions caps (3 years x $110,000 = $330,000) in a single financial year, by ‘bringing forward’ up to two years’ contribution caps. The rules for doing this have recently become even more complex, so ensure you talk to us before making your contribution.

What happens if I exceed my caps?
In short, you could be up for additional tax. The actual amount of tax will depend on your age, the type of contribution and the financial year in which the contribution was made.

Exceeding your concessional cap
Going over your concessional contributions cap, generally means a bigger tax bill because the excess amount is counted as part of your assessable personal income.

Until 30 June 2021, you were also required to pay a penalty to the ATO called the excess concessional contributions (ECC) charge. This was removed from 1 July 2021, but you will still be up for additional tax.

If you exceed your annual concessional contributions cap, the ATO will notify you. Your excess contributions are then included in your assessable income, meaning they are taxed at your marginal tax rate, minus a 15 per cent tax offset to reflect the contributions tax you paid when the money entered your account.

You then have a choice:
• You can withdraw up to 85 per cent of your excess concessional contributions from your super.
• Or, if you choose to leave the contributions in your super account, they are counted towards your annual non-concessional contributions cap. This may create additional challenges if you have also made large non-concessional contributions.

Exceeding your non-concessional cap
Making non-concessional contributions that go over your annual cap also results in a larger tax bill, as these excess contributions are taxed at the top tax rate of 47 per cent (including the Medicare levy).

The ATO will notify you and you can then choose to withdraw your excess contributions and 85 per cent of the earnings on them. Generally, these earnings will be taxed at your marginal tax rate less a tax offset.

However, if you decide to leave your excess non-concessional contributions in your super account, they are taxed at 47 per cent, even if your personal marginal tax rate is lower. As non-concessional contributions are from after-tax money, this means you are paying double tax, because the tax amount must be paid from money in your super account.

Making additional voluntary super contributions is a great way to boost your retirement savings, but as you can see, it is important to know your limits.

Many Australians don't know how their super fund has performed or what it invests in. Are you one of them? Here's what to check and why it matters. Do you know how your super fund performed over the last two years? Many Australians don’t and are working towards their financial future without fully understanding one of their most important assets and without a clear plan for how their super may support them in retirement. That's not surprising, as many people view super as something that should run quietly in the background while they're busy with careers, families and everything else that life throws at them. But when you’re not sure what’s happening behind your balance, it’s harder to know whether you’re on track, whether your current approach reflects your goals or what opportunities might be available to help you make the most of what you’ve built so far. Your super isn't sitting in an account, it's invested Super is invested by a fund on your behalf across a mix of assets, with those investments working to grow your balance over time. Those include: Shares Ownership in Australian and international publicly listed companies. Their value can rise and fall, sometimes substantially over short periods but shares can provide capital growth over the long term. Property and infrastructure Real assets like office buildings, shopping centres, airports and energy networks. They can produce income and don't always behave in the same way as share markets, helping diversify investment holdings. Fixed interest and bonds Lending to governments and companies in return for interest. They can provide regular income and be steadier than shares, although returns and risk vary depending on the investment. Cash Generally, the most stable and lowest risk investment type. It can provide stability and faster access to money but typically offers lower longer term return potential. The investment option you choose determines the mix of assets held in your super based on your risk appetite. Most super funds offer options from conservative to high growth. If you’re young, a growth option with a higher exposure to growth assets like shares could offer higher returns over time – but it also comes with higher risk. As retirement nears, you might want to consider a more conservative approach with more defensive assets, like bonds for example to protect your savings. If you've never made a choice, you're probably in your fund's default option, which is designed to suit a broad membership. It’s worth knowing whether the mix you're in matches your circumstances and goals, including how far you are from retirement. Why performance alone is not a true comparison If you're thinking about how your super compares, returns are often where people start. The trouble is that a return figure means nothing without context: What it's being compared to Growth and conservative options invest differently and with different levels of risk. Compare like with like or the comparison may not be genuine. The comparison period A single year can be heavily influenced by short term market conditions. Super is measured in decades, so five, seven and ten year returns tell you far more about whether a fund is consistently doing its job, albeit not a predictor of future performance. Fees and tax Published returns should reflect investment fees, costs and tax but administration fees may be charged separately from your balance. Two funds quoting the same return can leave you in meaningfully different places once all fees are accounted for. Then there are the things that returns can't show you at all. For example, what insurance is attached to your account and what it's costing you, whether the fund offers guidance, tools and advice or simply sends a statement once a year. Another consideration maybe the level of support available when you need it. When comparing funds, it's worth looking at the full picture, including performance, fees, investment options, retirement support and member benefits. What today’s decisions mean tomorrow To understand how your super stacks up, start here: Find your investment option It's on your annual statement and in your online account. Look at what's in it Your fund publishes the asset allocation (shares, cash etc.) for each investment option. Check the long-term return for that option Focus on five and ten year returns, not just last year and compare them with equivalent options. Understand the total cost Add together administration fees, investment fees and insurance premiums as an annual dollar figure. Comparing super is about working out which option will perform best for you. Before you jump in, it’s worth understanding what's behind the numbers so you can make decisions based on more than a headline return. Knowing where you stand is the first step A super balance tells you where you are today. Understanding how your super is invested, how it compares and whether it's aligned with your goals helps show whether you're heading in the right direction.

More Australians are choosing to take direct control of their retirement savings by establishing a self-managed super fund (SMSF) and according to the SMSF Association, Aussies now see their super as an important part of building and managing their overall wealth.
