How to boost your super with a lump sum

Shane Lee • September 4, 2023

If you’re lucky enough to have received a windfall, perhaps an inheritance or a retrenchment payout, your first decision will be what to do with it.

Assuming you have decided against a shopping splurge, finding the best place to invest a lump sum is all about the effect on your tax bill and how soon you will need access to the funds.

For those interested in investing their lump sum for a longer term, superannuation is one approach because of its tax benefits.

But be aware that, while super can be a tax-effective investment, there are limits on how much you can pay into your super without having to pay extra tax. These are known as  contribution caps.

Different types of contributions

There are two types of super contributions you can make – concessional and non-concessional – and contribution caps apply to both.

Concessional contributions are paid into super with pre-tax money, such as the compulsory contributions made by your employer. They are taxed at a rate of 15 per cent.

Non-concessional or after-tax contributions are paid into super with income that has already been taxed. These contributions are not taxed.

So, the tax you pay depends on whether:

  • the contribution was made before or after you paid tax on it
  • you exceed the contribution caps
  • you are a  high income  earner (If your income and concessional contributions total more than $250,000 in a financial year, you may have to pay an extra 15 per cent tax on some or all of your super contributions.)

Investing after-tax income

There are many  different types of after-tax contributions  that can be made to your super including contributions your spouse may make to your fund, contributions from your after-tax income, an inheritance, a redundancy payout or the proceeds of a property sale.

Based on current rules, the annual limit for non-concessional or after-tax contributions is $110,000. You can also bring-forward two financial years’ worth of non-concessional contributions and contribute $330,000 at once but then you can’t make any further non-concessional contributions for two financial years. Note that are certain limitation on these types of contributions.

It is also useful to note that, under certain conditions, there are some types of contributions that do not count towards your cap. These include: personal injury payments, downsizer contributions from the proceeds of selling your home and the re-contribution of COVID-19 early release super amounts.

The  Downsizer  scheme allows the contribution of up to $300,000 from the proceeds of the sale (or part sale) from your home. You will need to be above age 55 but there is no upper age limit, the home must be in Australia, have been owned by you or your spouse for at least 10 years, the disposal must be exempt or partially exempt from capital gains tax and you have not previously used a downsizer contribution.

Giving your super a boost

A review of your super balance and some quick calculations about your projected retirement income might inspire you to give your super a boost but not everyone has access to a lump sum to invest.

A strategy that uses smaller amounts could include any amount from your take-home pay. These contributions will count towards your non-concessional or after-tax cap.

Alternatively, you add to your super from your pre-tax income using, for example, salary sacrifice. These types of concessional or pre-tax contributions attract a different contribution cap: $27,500 per year, which includes all contributions made by your employer.

If your super fund balance is less than $500,000, your limit may be higher if you did not use the full amount of your cap in earlier years. You can check your cap at ATO online services in your myGov account.

The rules for super contributions can be complex so give us a call to discuss how best to maximise your benefits while avoiding any mistakes.

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.
