Investing an inheritance into super: What you need to know

Receiving an inheritance is usually a mix of emotions. Although you’re happy about the improvement in your finances, it’s coupled with sadness at the loss of a family member or friend.

It can also be challenging working out the best way to manage the bequest.

While your first thought may be to pay off your mortgage or take a holiday, it’s worth considering putting at least some of the money away for your retirement.

Points to consider before making a decision

It’s important to carefully review your current financial situation before you decide how to use an inheritance:

  • Look at things like your level of debt, income and cash flow, how much risk you feel comfortable with, and how close you are to retirement.
  • List your future financial goals such as taking early retirement or travelling overseas for an extended period.
  • Consider eliminating any significant non-deductible debts like credit cards and car or personal loans to reduce your financial stress level.
  • Think about the cost of investing outside the super system. For example, buying shares or a rental property outside super has administration and transaction costs like stamp duty or brokerage fees, while any income or capital gains may be taxed more heavily.

There’s a lot to consider, so it may be wise to talk to an independent financial adviser. They can help you work out your financial goals and offer personalised advice about the best course of action for your financial situation.

Super tip

Inheritances can involve significant sums of money, so take your time and don’t let emotions sway your judgement. Think carefully about your decision and your financial and lifestyle priorities. Avoid making a snap move you may regret later when you’re feeling less emotional about your loss.

If you decide to take the opportunity to invest for your future and you’re comfortable with locking your money away until you’re at least 60, the super system is an attractive option. Here is what you need to know.

Contributing an inheritance into super: 10 points to weigh up

1. Lowers your investment tax bill

Investment earnings in super are taxed at a maximum of 15%. This may be much lower than the personal income tax rate you pay outside super, which can be as much as 47%.

When you retire or turn 65, you can use your super to start an income stream where investment earnings are completely tax free.

To sweeten the deal further, withdrawals from super are generally not taxable when you withdraw your money after turning 60. Learn how super is taxed and review our tax guide to accessing super after turning 60.

2. Your contribution could be tax deductible

If you claim a tax deduction for personal contributions to super, you can trade your marginal income tax rate for the 15% super tax rate.

If you have a large amount to invest, you can consider spreading your contributions over several financial years to stay within annual contribution caps and maximise the benefit of your tax deduction.

3. Contribution amounts are limited

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

A non-concessional contribution is money that has been taxed before you add it to super. This includes your personal contributions when you don’t claim a tax deduction and contributions from your spouse. The annual non-concessional contribution cap for 2024–25 is $120,000. The cap is zero if your total super balance was $1.9 million or more on 30 June 2024.

Concessional contributions are amounts that have not been taxed before being added to super such your employer’s contributions and amounts you have chosen to salary sacrifice. Personal contributions you claim as a tax deduction are also concessional. The concessional contribution cap for 2024–25 is $30,000.

These limits might seem restrictive, but there are two super rules that can help you to contribute more.

The bring-forward rule applies to non-concessional contributions and can allow contributions of up to three times the usual cap in one year. Your total super balance on 30 June determines whether you’re eligible to use a bring-forward arrangement in the following financial year and the total amount you can contribute.

For concessional contributions, the carry-forward rule allows you to use up any concessional contribution cap you didn’t take advantage of in the prior five financial years in addition to the current year’s cap. To make a carry-forward contribution, your total super balance must be below $500,000 on 30 June of the prior financial year.

4. Age limits apply

Your plans to put your inheritance into super may be challenged by the age limits applying to super contributions.

If you’re 75 or more, the only amounts your super fund can accept are compulsory contributions from your employer and downsizer contributions you make after selling your home.

If you’re 67 or more and you plan to make a tax-deductible personal contribution you need to meet the work test. The work test requires that you work for 40 hours or more in a period of 30 consecutive days at least once during the financial year that you make the contribution.

Find out more about the work test for tax-deductible contributions.

5. Access to more investment options

Large super funds offer access to a wide range of asset classes. Personal investors often find it hard to gain exposure to asset classes like overseas bonds, infrastructure, commercial and international property, private equity and commodities. Investing through a super fund makes it easier to access these assets.

Learn about investing in infrastructure assets.

6. Potential to improve social security benefits

While you’re under age 67, money you have in super is not assessed in Centrelink means tests. If you or your partner are eligible for benefits, choosing to invest some of your inheritance in super could help to retain those benefit payments while simultaneously giving your retirement savings a welcome boost.

7. You could qualify for a bonus from the government

If you move some of your inheritance into your super account as a non-concessional contribution, you may qualify for a co-contribution payment of up to $500.

Learn about super co-contributions.

8. Super isn’t easily accessible

Once your inheritance is in your super account, you won’t be able to immediately access the money. Except in very specific circumstances, super can’t be withdrawn until you turn 60.

If you plan to use your inheritance to retire before 60 or want earlier access to your investment for any other reason, investing outside super may be preferable.

Learn about the conditions of release that permit access to super.

9. What about the mortgage?

If you have a mortgage, paying it down with any lump sum that comes into your hands can be tempting. Repaying even some of your mortgage debt will reduce interest and potentially free up other income to invest for the future. Being mortgage-free early can also offer a sense of security and peace of mind.

Financially though, investing in your super is likely to come out ahead, particularly if you have room under your concessional cap to make deductible contributions. Tax savings and strong investment growth in super can combine to outpace the interest savings possible from repaying the mortgage.

Of course, the comparison depends on your personal situation.

Learn more about the super vs mortgage decision.

10. Very high balances

Because super is such a tax-effective way to save, the government imposes additional rules on people with high balances.

One of these is the transfer balance cap (TBC). This is the maximum that one person can use to invest in retirement income streams where investment earnings are tax free. The TBC stands at $1.9 million in 2024–25. Any excess amount you have at retirement can be kept in a super accumulation account where investment returns are taxable or can be withdrawn to be invested elsewhere.

If proposed legislation is passed, super balances above $3 million will attract additional tax on their growth from 1 July 2025.

Depending on your situation, these caps could make investing your inheritance in super a little less attractive.

Case studies

Centrelink troubles

Beth, age 59, and her husband Max, 68, have just received $500,000 from the estate of Beth’s late mother. Beth cares for Max full time because he is significantly disabled after having a stroke two years ago. Max receives Age Pension plus $10,000 a year from his super pension (current balance $200,000) while Beth is eligible for carer’s pension and carer allowance. They have $25,000 in assessable assets outside super including their car and home contents and own their home but have no other savings except Beth’s super of $250,000.

Prior to receiving the inheritance, the couple were receiving a total of $47,774 per year from Centrelink in addition to Max’s super pension. They were comfortable living on their income.

After declaring the addition of $500,000 to their savings, the couple’s combined Centrelink payments have reduced to $27,864 per year, nearly $20,000 less than before. They can’t live on the lower income, but don’t want to draw on Beth’s inheritance for their additional needs if it’s not necessary.

After considering the options, Beth chooses to contribute $360,000 as a lump sum to her super account. Under the bring forward rule, this contribution is permitted and considered to be within the non-concessional contribution cap.

After making the contribution, the couple’s Centrelink entitlements return to the same level as before receiving the inheritance. This is because Beth’s super is not assessable in Centrelink’s means tests while she is under 67.

Beth and Max have kept the remaining $140,000 from the inheritance in a high-interest bank account that is accessible at any time. When Beth turns 60, she will also be able to take money out of her super account if she chooses because she is retired and does not intend to return to work.

When Beth turns 67, her super will begin to be assessed by Centrelink. When this occurs, she plans to consider starting her own super pension to provide any additional income she needs on top of her reduced Centrelink benefits.

Tax-deductible contributions

Angelo is 45 and earning $90,000 per year. He has received a lump sum inheritance of $135,000. Angelo has decided he wants to invest this money for his future, and he is comfortable with adding it to his super knowing he can’t access it again until he turns at least 60.

Last 30 June, Angelo’s total super balance was $200,000 and he has unused concessional contribution cap of $82,500 available from the last five years, so he is eligible to carry forward unused concessional cap space.

He decides to make annual tax-deductible contributions to super that will reduce his taxable income to as little as $45,000 while staying within the concessional cap he has available each year (including carried forward cap). This will ensure his contributions are taxed at 15% and will generate a tax deduction on income he would otherwise pay 32% tax on (including Medicare Levy).

We have laid out Angelo’s plan in a table based on the current concessional contribution cap of $30,000 per year, the 2024–25 tax rates, and assuming he continues to earn $90,000 per year. Angelo will use the annual tax refund his contributions generate to add to the amount he has available to contribute during the following years.

Employer super contributions Angelo’s tax-deductible contribution Unused cap space remaining at year end Tax refund Savings remaining outside super at year end*
Year 1 $10,800 $45,000 $56,700 $14,400 $104,000
Year 2 $10,800 $45,000 $30,900 $14,400 $73,400
Year 3 $10,800 $45,000 $5,100 $14,400 $42,800
Year 4 $10,800 $24,300 $0 $7,776 $26,276
Year 5 $10,800 $19,200 $0 $6,114 $13,190
Year 6 $10,800 $19,200 $0 $6,114 $0

*(initial inheritance – contributions to super + tax refund)

In the sixth year shown in the table, Angelo plans to contribute $19,200 but expects to have only $13,190 remaining from his inheritance. He will make the contribution using the remaining inheritance, plus $6,010 from his emergency savings. When Angelo’s tax return is processed, he will receive a refund of $6,114 that he can reinvest in his emergency savings account.

Based on his planned strategy, Angelo has calculated he can turn his $135,000 inheritance into $168,045 added to his super. This is the sum of all his tax-deductible contributions over six years, minus 15% contribution tax. The additional $33,045 in savings has been generated thanks to the difference between Angelo’s 32.5% marginal tax rate and the 15% tax on super contributions.

Angelo will need to tweak his rough plan each year based on his actual taxable income, employer contributions and the remaining unused concessional cap space he has available. He plans to make his deductible contributions each June when this information is readily available.
