Spouse super contributions
You can support your partner’s super in two ways: by making after tax contributions to their account or by splitting some of your concessional contributions with them.
In many families, the partner that contributes more of the unpaid caregiving will generally have less super in retirement. This is known as the super gap. On average, men have 30% more super at retirement than women1.
To help close the gap, primary income earners can add to their spouse’s super.
By making contributions to your spouse’s super2, you can help strengthen your combined retirement savings while potentially benefiting from a tax offset.
You don’t have to be married
A spouse means:
- a person who is legally married to you, or
- a person who lives with you on a genuine domestic basis in a relationship as a couple, or
- a person with whom you are in a relationship that is registered under law of a State or Territory.
How after-tax spouse contributions work
To help boost retirement savings, the primary income earner can make spouse contributions into their partner’s super from their take-home pay. These contributions are classified as after-tax (non-concessional) contributions, meaning they won’t be taxed again when deposited into the spouse’s account. Spouse contributions form part of the receiving spouse’s non-concessional contributions cap.
For spouses earning less than $40,0003 per year:
- The contributing spouse may be able to claim a tax offset of up to 18% on the first $3,000 they contribute to their spouse’s super account. This could result in a maximum offset of $540 each year.
- The tax offset gradually decreases for every dollar earned over $37,000.
Eligibility criteria
To qualify for the spouse contribution tax offset, both partners must meet specific requirements:
- you must be spouses
- the receiving spouse must be under the age of 754
- the super fund must have your spouse’s Tax File Number (TFN) on record
- you must both be Australian residents
- the receiving spouse must not have exceeded their non-concessional contributions cap in the year in which the contribution is made. Their super balance must have been less than the ‘general transfer balance cap’ at the end of the previous financial year. The general transfer balance cap is $2.1 million as at 1 July 2026
- you and your spouse must not be living separately and apart on a permanent basis.
Benefits of spouse contributions
Contributing to your spouse's super can provide several advantages.
Potential tax advantages

Help cover their insurance costs
Contributing to your spouse’s super can help maintain their insurance cover for illness, injury or death.
Help bridge the super gap

Split before-tax super contributions
Here is another way you can help boost your spouse’s retirement savings.
Regardless of your age, you can split (share) your before-tax (concessional) contributions for the financial year with your spouse, including both employer contributions and salary sacrifice payments. Any contributions you make to super are counted as part of your contribution limits, not your spouse’s limits. You’ll need to complete the Split your super contributions with your spouse form and send it back to us.
Contribution splitting limits
You can split the lesser of:
- 85% of your before-tax contributions each financial year, or
- your before-tax contributions cap for that financial year5
You must split at least $1,000 with your spouse.
Age requirements
Your spouse must be under 60 years of age, or between 60 and 65 and not retired when contributions are split.
Use our super contributions calculator to track your super as a couple or individually.
Things to consider
Before deciding if spouse super contributions are right for you, there are a few things you should consider.
-
Contribution limits
To qualify for the maximum tax offset, you’ll need to contribute $3,0003. Contributions above this amount are ineligible for the offset and must remain within the $130,000 non-concessional cap. -
Maximise your offset
Keep in mind that the maximum tax offset is capped at $540, regardless of the total amount you contribute to your spouse’s super. -
Contribution splitting
Before proceeding, check if your super fund:
- allows contribution splitting (before-tax)
- charges fees for this service.
Both you and your spouse must be Australian citizens and in a relationship (legally married, de facto or registered under law of a State or Territory) when making contributions.
