Spouse super contributions – what are the benefits?

If your partner is earning a low income, working part-time, or currently unemployed, boosting their super could be a smart financial move for both of you.

When your partner isn’t earning much, or is out of work, their super might not be growing enough to support them in retirement. By contributing to their super, you may not only help them but also enjoy some tax benefits yourself.

We’ll explore how the spouse contributions tax offset works and how it differs from contribution splitting.

The spouse contributions tax offset

Are you eligible?

To be entitled to the spouse contributions tax offset:

  • You need to make a non-concessional contribution to your spouse’s super. This means you add money from your after-tax income and don’t claim a tax deduction for it.

  • You must be married or in a de facto relationship together and are not living apart or separately.

  • You must both be Australian residents.

  • Your spouse’s income should be $37,000 or less for the full tax offset, and under $40,000 for a partial tax offset.

  • Your spouse is under 75 years of age, and their total superannuation balance is less than the general transfer balance cap ($1,900,000 for 2024-25) as at 30 June of the prior year.

What are the financial benefits?

If eligible, you can generally make a contribution to your spouse’s super fund and claim an 18% tax offset on up to $3,000 through your tax return.

To be eligible for the maximum tax offset, which works out to be $540, you need to contribute a minimum of $3,000 and your partner’s annual income needs to be $37,000 or less. If their income exceeds $37,000, you’re still eligible for a partial offset. However, once their income reaches $40,000, you’ll no longer be eligible for any offset, but can still make contributions on their behalf.

Are there limits to what can be contributed?

You can’t contribute more than your partner’s non-concessional contributions cap, which is $120,000 per year for everyone, noting any non-concessional contributions your partner may have already made.

However, if your partner is under 75 and eligible, they (or you) may be able to make up to three years of non-concessional contributions in a single income year, under bring-forward rules, which would allow a maximum contribution of up to $360,000.

Another thing to be aware of is that non-concessional contributions can’t be made once someone’s super balance reaches $1.9 million or above as at 30 June 2024. So you won’t be able to make a spouse contribution if your partner’s balance reaches that amount. There are also restrictions on the ability to trigger bring-forward rules for certain people with large super balances (more than $1.66 million in 2024-25). 

There are also different super balance limits in place if you want to take advantage of the bring-forward rules.

How contributions splitting differs

Another way to increase your partner’s super is by splitting up to 85% of your concessional super contributions with them, which you either made or received in the previous financial year. Concessional super contributions can include employer and or salary-sacrifice contributions, as well as voluntary contributions you may have claimed a tax deduction for.

What rules apply for contribution splitting?

To be eligible for contributions splitting, your partner must be between age 60 (preservation age) and 65 (and not retired). 

Are there limits to how much can be contributed?

Amounts you split from your super into your partner’s super will count toward your concessional contributions cap, which is $30,000 per year for everyone.

On top of this, unused cap amounts accrued in the last 5 years can also be contributed, if they’re eligible. Note, this broadly applies to people whose total super balance was less than $500,000 on 30 June of the previous financial year.

Do all super funds allow for this type of arrangement?

You’ll need to talk to your super fund to find out whether it offers contributions splitting, and it’s also worth asking whether there are any fees.

What else you and your partner should know

  • If either of you exceeds super contribution caps, additional tax and penalties may apply.

  • The value of your partner’s investment in super, like yours, can go up and down, so before making contributions, make sure you both understand any potential risks.

  • The government sets rules about when you can access your super. Generally, you can access it when you’ve reached age 60 (preservation age) and retire.

  • While you can’t personally make further non-concessional contributions into your super once you have a total super balance of $1.9 million or above (as at 30 June of the previous financial year), it’s still possible to make contributions to your partner’s super (noting the caps).

Where to go for more information

Your circumstances will play a big part in what you both decide to do. And, as the rules around spouse contributions and contributions splitting can be complex, it’s a good idea to chat to your financial adviser to make sure the approach you and your partner take is the right one.

Australians are living longer than ever before due to a combination of factors including improved healthcare, better living conditions and over all better quality of life. With this longevity comes the challenge of ensuring financial security throughout a longer retirement. Data from the Australian Bureau of Statistics (ABS) shows that life expectancy at birth is now 81.1 years for males and 85.1 years for females1. Despite the increases in these averages, many Australians will live well beyond these ages, making planning for your retirement income more important than ever. What is longevity risk? Longevity risk refers to the possibility of outliving your savings. Living longer allows you to enjoy the fruits of life for longer but it also means planning carefully to ensure your savings last as long as you do. For Australian retirees, this is especially important, as the Age Pension alone may not be enough to cover all living expenses over an extended period. According to the Challenger Retirement Happiness Index2, 72% of Australians aged 60+ report that the rising cost of living has adversely impacted their financial security, with 34% admitting the impact was significant. This highlights the importance of planning for longevity risk to maintain financial confidence in retirement. Building financial security for the future To ensure a comfortable and secure retirement, it’s important to take proactive steps to manage longevity risk. Here are some key considerations: 1. Understand how long your retirement savings may last Knowing how long you might live can help you plan your finances to last throughout retirement. Factors like health, lifestyle and family history can play a role in estimating life expectancy. 2. Understand your income sources Retirement income can come from a mix of sources, including the Age Pension, superannuation, personal savings and investments. For many Australians, the Age Pension alone may not be enough to cover all living expenses, especially if superannuation or other savings run out. Adding a source of regular income such as a lifetime annuity to your retirement income plan can help you manage the risk of outliving your savings. By using some of your super or other money to set up a lifetime income stream, you could create an additional layer of secure income that complements the Age Pension, if you are eligible. This approach helps to provide peace of mind by ensuring you have a regular source of income that can cover essential needs throughout your life. This can form part of a comprehensive retirement income plan. 3. Use planning tools and resources Make a budget The Age Pension is a key safety net for many Australians. Consider how it works, including eligibility and its role alongside superannuation and lifetime income streams. For personalised guidance to help you make informed decisions about your finances, consider accessing free services like the Financial Information Service (FIS) offered by Services Australia or see a Financial Adviser. The benefits of financial security Financial security can transform retirement into a time of freedom and fulfilment, allowing retirees to focus on what truly matters. With a lifetime income stream you can enjoy meaningful activities like traveling, pursuing hobbies or spending quality time with loved ones without the stress of financial uncertainty. The Challenger Retirement Happiness Index2 reveals that 41% of Australians aged 60+ see "having enough money to enjoy retirement" as essential for happiness, while 33% value knowing their money will last. This financial confidence provides the foundation for a retirement filled with confidence, happiness and peace of mind. Planning for a confident retirement A well thought out retirement plan provides the confidence to enjoy life without the constant worry of running out of money. By understanding longevity risk and taking proactive steps, you can feel more confident that your retirement income will last as long as you do. Source: Challenger
