Contributing to your spouse's super can earn you a tax offset of up to $540 while helping balance retirement savings between partners. Here's everything you need to know.
What Are Spouse Super Contributions?
Spouse super contributions allow you to make after-tax (non-concessional) contributions to your spouse's superannuation fund. If your spouse earns below certain income thresholds, you can claim a tax offset of up to $540 on your tax return. This strategy is particularly valuable for couples where one partner has reduced income due to caring responsibilities, part-time work, or career breaks.
Why Spouse Contributions Matter
The super gap is real: Women retire with an average of $157,050 less super than men due to career breaks for caregiving, part-time work, and the gender pay gap. Spouse contributions help bridge this gap while providing immediate tax benefits.
Who Can Make Spouse Contributions?
To make spouse super contributions and claim the tax offset, both you and your spouse must meet certain eligibility criteria:
Eligibility Requirements
| Requirement | Contributing Spouse | Receiving Spouse |
|---|---|---|
| Relationship | Legally married or de facto partner | Legally married or de facto partner |
| Living arrangements | Must not be living apart permanently | Must not be living apart permanently |
| Age requirement | Any age | Under 75 years old |
| Income for tax offset | No limit (but must have tax liability) | Below $40,000 for full offset |
| Super balance | No limit | Under $1.9 million (transfer balance cap) |
Spouse Income Limits for Tax Offset
The spouse tax offset is based on your spouse's "assessable income plus reportable fringe benefits plus reportable employer super contributions." Here's how the offset phases out:
| Spouse's Income | Your Contribution | Tax Offset Available | Offset Rate |
|---|---|---|---|
| $0 - $37,000 | $3,000 | $540 | Full (18%) |
| $37,001 - $38,000 | $3,000 | $450 | Reduced |
| $38,001 - $39,000 | $3,000 | $360 | Reduced |
| $39,001 - $40,000 | $3,000 | $270 | Reduced |
| Over $40,000 | $3,000 | $0 | Nil |
How the Offset is Calculated
The tax offset equals 18% of contributions up to $3,000. For every dollar your spouse earns above $37,000, the maximum contribution eligible for the offset reduces by $1. So at $38,000 income, only $2,000 is eligible ($360 offset). At $40,000+, no offset is available.
How to Calculate Your Spouse Tax Offset
Let's walk through the calculation with a practical example:
Example: Sarah and Michael
Sarah works full-time earning $95,000/year
Michael works part-time earning $28,000/year (caring for children)
Example with Phase-Out Income
Example: Alex and Jordan
Jordan earns $38,500/year
Alex contributes $3,000 to Jordan's super
Contribution Caps to Be Aware Of
Spouse contributions count toward your spouse's non-concessional (after-tax) contribution cap. Here are the key limits for 2024-25:
| Cap Type | Annual Limit | Notes |
|---|---|---|
| Non-concessional cap | $120,000 | Per person per year |
| Bring-forward rule | $360,000 | 3 years' cap in one year (if under 75) |
| Total super balance limit | $1.9 million | No non-concessional contributions above this |
| Optimal for tax offset | $3,000 | Maximum for full $540 offset |
Exceeding Caps Warning
If spouse contributions cause your partner to exceed their non-concessional cap, excess contributions will be taxed at their marginal rate plus an interest charge. For large contributions, check your spouse's existing contributions and total super balance first.
How to Make Spouse Super Contributions
Step-by-Step Process
- Check eligibility: Ensure your spouse's income is under $40,000 and they're under 75
- Verify cap space: Check your spouse's non-concessional contribution cap remaining
- Get super fund details: You need your spouse's super fund BSB, account number, and member number
- Make the contribution: Transfer funds via BPAY or direct deposit (must come from YOUR bank account)
- Complete the form: Your spouse's super fund may require a contribution form specifying this is a spouse contribution
- Keep records: Save proof of payment and contribution date for tax purposes
Important Timing
- Contributions must be received by the super fund by 30 June to count for that financial year
- Allow 3-5 business days for BPAY processing
- Make contributions by mid-June to ensure they're processed in time
How to Claim the Tax Offset
Claiming the spouse super contribution tax offset is straightforward when lodging your tax return:
At Tax Time
- Log into myGov and access myTax
- Go to "Deductions" section
- Select "Superannuation" then "Spouse super contributions"
- Enter the total contributions made to your spouse's super
- Enter your spouse's income details
- The offset will be calculated automatically
Using a Tax Agent
Provide your tax agent with:
- Proof of spouse contributions (bank statements, super fund receipts)
- Your spouse's income details (payslips, payment summaries)
- Your spouse's reportable employer super contributions
Spouse Contributions vs Contribution Splitting
Don't confuse spouse contributions with contribution splitting - they're different strategies:
| Feature | Spouse Contributions | Contribution Splitting |
|---|---|---|
| Source of funds | Your after-tax money | Your existing super contributions |
| Tax benefit | Up to $540 tax offset | No direct tax benefit |
| Cap impact | Uses spouse's non-concessional cap | No cap impact (transfers within caps) |
| Timing | Any time during financial year | Must apply after EOFY for prior year |
| Best for | Low-income spouse (under $40k) | Balancing super between partners |
Pro Tip: Use Both Strategies
You can use both spouse contributions AND contribution splitting to maximize retirement savings for a lower-earning partner. Contribute $3,000 for the tax offset, then split your employer contributions as well.
When Spouse Contributions Make Sense
Ideal Scenarios
Stay-at-Home Parent
Partner caring for children with little or no income. Full $540 offset available, helps build retirement savings.
Part-Time Worker
Spouse earning under $37,000 part-time. Tax offset plus building super during reduced work period.
Career Break
Partner taking study leave, sabbatical, or between jobs. Maintains super growth during break.
Self-Employed Low Income
Spouse running a business with low drawings. Building super for retirement when business income is reinvested.
When It May Not Be Worth It
Consider Carefully If:
- Your spouse earns over $40,000 (no offset available)
- You don't have $3,000 in after-tax savings to spare
- Your spouse's super balance is near $1.9 million
- You have higher-interest debt to pay off first
- Your own super needs boosting more urgently
Long-Term Impact: The Power of Spouse Contributions
Small annual contributions compound significantly over time. Here's the potential growth of $3,000 annual spouse contributions:
