Spouse Super Contributions: Tax Offsets and Benefits

If you're looking for ways to boost your spouse's superannuation while getting a tax benefit yourself, spouse super contributions might be exactly what you need. It's a smart strategy that can help couples build wealth together, and the Australian Tax Office (ATO) even rewards you with a tax offset of up to $540 per year if you meet the eligibility criteria. Whether you're planning for retirement or want to help your partner catch up on their super, understanding how spouse contributions work is essential.

What Are Spouse Super Contributions?

Spouse super contributions are after-tax contributions you make to your spouse's superannuation account on their behalf. Unlike salary sacrifice or concessional contributions that come from your pre-tax income, spouse contributions come straight from your take-home pay. You don't claim a tax deduction for these contributions, but you may be eligible for a tax offset instead—which is actually a better deal for many Aussies.

There are two main ways to boost your spouse's super:

• Spouse contributions – Direct after-tax contributions you make to your spouse's account
• Contribution splitting – Transferring some of your own superannuation to your spouse's account

This article focuses on spouse contributions, which are the most straightforward approach for most people.

Who Can Make Spouse Contributions?

Your Eligibility as the Contributor

The good news is that there are no age restrictions for the person making the contribution. You can be any age and still contribute to your spouse's super. However, you do need to meet these basic criteria:

• You must be an Australian resident when making the contribution
• You must have assessable income from any source
• You and your spouse must not be living separately and apart on a permanent basis
• You must be in a legal marriage or de facto relationship (including those registered under state or territory laws)

Your Spouse's Eligibility

Your spouse needs to meet specific criteria to receive contributions and, importantly, to qualify for the tax offset:

• They must be under 75 years old
• They must be an Australian resident with a valid Tax File Number (TFN)
• Their total assessable income must be less than $40,000 for the financial year
• They must have a superannuation account to receive the contributions

The Tax Offset: Your Key Benefit

This is where spouse contributions become really attractive. You can claim a tax offset of up to $540 per year if you meet the eligibility criteria. This is a direct reduction in your tax bill, which is more valuable than a tax deduction.

How the Tax Offset Works

To claim the maximum offset of $540, you need to contribute at least $3,000 to your spouse's account, and their income must be $37,000 or less for the financial year.

The tax offset is calculated as 18% of the lesser of either:

• $3,000 minus the amount your spouse's income exceeds $37,000, or
• The total spouse contributions you made that income year

Partial Tax Offset Example

Let's work through a practical example. Say you contribute $3,000 to your spouse's account and they earned $37,500 that financial year:

• $3,000 – $500 (income over $37,000) = $2,500
• Tax offset = 18% of $2,500 = $450

So even though your spouse's income is slightly over the threshold, you still get a $450 tax offset instead of the maximum $540.

Income Thresholds

The tax offset phases out gradually:

• Up to $37,000 income: Full tax offset available (up to $540)
• $37,001 to $39,999 income: Partial tax offset (reduced amount)
• $40,000+ income: No tax offset available, but you can still make contributions

Contribution Limits and Caps

Non-Concessional Contribution Cap

Spouse contributions count as non-concessional contributions, which means they're subject to the non-concessional contributions cap of $120,000 per financial year. This is the maximum your spouse can receive in non-concessional contributions from all sources combined in a single year.

If your spouse has already made their own contributions during the year, those count towards this cap too.

Bring-Forward Rules

If your spouse is under 75 and eligible, they may be able to use bring-forward rules to make up to three years' worth of non-concessional contributions in a single income year. This would allow a maximum contribution of up to $360,000 in one year, though this is subject to their total super balance.

Total Super Balance Restrictions

Non-concessional contributions can't be made once someone's super balance reaches $1.9 million or above as at 30 June 2024. If your spouse's balance is approaching this threshold, you'll need to check with their super fund before making contributions.

How to Make Spouse Contributions

Making a spouse contribution is straightforward. You'll typically be able to contribute via:

• BPAY
• Cheque
• Direct bank transfer (depending on your super fund)
• Your super fund's online platform

You'll need to know your spouse's account details, including their account number and their super fund's details. Check with their super fund for the specific payment methods they accept.

Key Conditions You Must Meet

To claim the tax offset for spouse contributions, all of these conditions must be satisfied:

• You make a spouse contribution into your spouse's super account
• You don't claim a tax deduction for the contributions
• Both you and your spouse are Australian residents when the contribution is made
• You and your spouse are not living separately and apart on a permanent basis
• Your spouse's assessable income (including fringe benefits and salary sacrifice amounts) was less than $40,000 for the financial year
• Your spouse didn't exceed their non-concessional contributions cap that year
• Your spouse's total super balance was below the general transfer balance cap at the start of the financial year

Spouse Contributions vs. Contribution Splitting

It's worth understanding the difference between spouse contributions and contribution splitting, as they work quite differently:

Spouse Contributions: You contribute your own after-tax money to your spouse's account. This counts towards their non-concessional cap but not yours.

Contribution Splitting: You transfer some of your own superannuation to your spouse's account. This is a concessional contribution that counts towards your concessional cap ($30,000 per year), not your spouse's. Your spouse must be under their preservation age or between preservation age and 65 and not retired to be eligible.

For most people, spouse contributions are simpler and more accessible, especially if you want to claim the tax offset.

Why Spouse Contributions Matter for Your Retirement

Spouse contributions are a powerful wealth-building tool for couples. They help balance super between partners, which is particularly useful if one spouse has taken time out of the workforce for caring responsibilities or has had lower earning years. By boosting your spouse's super while claiming a tax offset, you're essentially getting the government to help you both save for retirement.

Over several years, the tax offsets add up. If you contribute $3,000 annually for 10 years and claim the maximum $540 offset each year, that's $5,400 in tax benefits while building $30,000 in your spouse's super balance (before investment returns).

Getting Started

If spouse contributions sound right for your situation, here's what to do next:

1. Check your spouse's current super balance and confirm they have an active account
2. Calculate your spouse's total assessable income for the financial year to see if they qualify for the tax offset
3. Confirm they're under 75 and that their super balance is below the general transfer balance cap
4. Contact your spouse's super fund to get their account details and payment methods
5. Make your contribution via BPAY, cheque, or bank transfer
6. Keep records of the contribution for your tax return
7. Claim the tax offset when you lodge your tax return with the ATO

Spouse super contributions are one of the few areas of superannuation where the ATO actively rewards you with a tax benefit. If your circumstances allow, it's worth taking advantage of this opportunity to strengthen your retirement savings as a couple.
