Spouse Super Contributions vs Contribution Splitting: What’s the Difference?

Spouse super contributions and contribution splitting are often confused.

They both involve your spouse.
They both involve super.
They both move money between partners.

But they are not the same strategy.

If you are searching for “spouse super vs contribution splitting” or even “85% spouse contribution”, this page will clarify the difference.

Quick decision guide

• If you want access to the $540 tax offset → you must make a direct spouse super contribution.
• If you want to rebalance concessional contributions already made → contribution splitting may be relevant.
• If you are not contributing new after-tax money → splitting is the only option.

Clarity of purpose matters more than the mechanics.

The short answer

• A spouse super contribution is a new after-tax contribution made directly into your spouse’s super fund.
• Contribution splitting is a rollover of concessional contributions you already made to your own super.

Only one of these may qualify for the $540 tax offset.

---

Side by side comparison

Contribution splitting is subject to restrictions on the type and amount of contributions that can be split, and your fund has discretion to allow or refuse a request.

What is a spouse super contribution?

A spouse super contribution is:

• An after-tax contribution made directly into your spouse’s super.
• Treated as their non concessional contribution.
• Not deductible to you.
• Potentially eligible for a tax offset of up to $540.

Eligibility depends on:

• Your spouse’s income being below $40,000.
• Their non concessional cap not being exceeded.
• Their total super balance being below the general transfer balance cap immediately before the income year.
• Being under 75 at the time of contribution for 2020–21 and later income years.

What is contribution splitting?

Contribution splitting allows you to split certain concessional contributions you have already made to your own super.

These typically include:

• Employer contributions.
• Personal contributions you claimed as a tax deduction.

You apply to your fund, generally after the end of the income year in which the contributions were made.

The amount split is treated as a rollover to your spouse. It is not treated as a new contribution for them.

This is important.

Because it is a rollover:

• It does not reduce your original concessional contributions.
• It does not change how those contributions count towards your concessional cap.
• It does not qualify for the $540 spouse tax offset.

Why the “85% rule” causes confusion

You may see references to an “85% spouse contribution”.

That does not relate to the $540 tax offset strategy.

It refers to contribution splitting, where up to 85% of eligible concessional contributions may be split. The 85% reflects the 15% contributions tax generally deducted inside the fund.

It is a separate mechanism entirely.

When might a spouse super contribution make sense?

A spouse contribution may make sense if:

• Your spouse earns less than $40,000.
• You want to receive the tax offset of up to $540.
• You want to increase the lower balance spouse’s super using after-tax savings.

It is most effective when the lower income spouse is below the $37,000 threshold, as that allows the full offset.

---

When might contribution splitting make sense?

Contribution splitting may be considered when:

• One spouse has significantly higher concessional contributions.
• You want to even out super balances over time.
• You are not contributing additional after-tax savings.
• You are not focused on receiving the spouse tax offset.

It is a balance management tool. It is not an offset strategy.

A simple example

Scenario 1: Spouse contribution

You contribute $3,000 after tax directly to your spouse’s super.

Their income is $30,000.

You may receive a $540 tax offset.

Scenario 2: Contribution splitting

You made $10,000 of concessional contributions to your own super.

After the end of the year, you apply to split a portion to your spouse.

No tax offset applies.

The split does not reduce your concessional cap usage.

Same couple. Very different outcomes.

---

Which one should you use?

They are not interchangeable.

If your goal is the $540 tax offset, you must make a direct spouse contribution.

If your goal is to rebalance existing concessional contributions without using new after-tax cash flow, contribution splitting may be appropriate.

The rule is simple. The objective determines the strategy.

FAQs

Is contribution splitting the same as a spouse super contribution?

No. A spouse super contribution is a new after-tax contribution made directly to your spouse’s super. Contribution splitting is a rollover of concessional contributions you already made to your own super.

Can I get the $540 tax offset if I split contributions?

No. The spouse tax offset only applies to direct non-concessional contributions made to your spouse’s super.

Does contribution splitting reduce my contribution cap?

No. The original concessional contribution still counts towards your concessional contributions cap, even if you later split it to your spouse.
