What this calculator does

The calculator estimates:

• Whether your spouse’s income is within the eligible range.
• Whether you qualify for the full or partial offset.
• The estimated tax offset amount, up to $540.

It uses the ATO formula:

18% of the lesser of:

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

The offset phases out once your spouse’s income reaches $40,000.

What income does the calculator use?

For the spouse offset test, income includes:

• Assessable income, ignoring any amount released under the First Home Super Saver Scheme.
• Total reportable fringe benefits.
• Total reportable employer super contributions.

This is broader than taxable income.

If you are not sure, check the ATO definition before relying on the result.

What this calculator does not do

This tool does not:

• Confirm residency eligibility.
• Confirm whether your spouse exceeded their non concessional contributions cap.
• Confirm whether your spouse’s total super balance was below the general transfer balance cap immediately before the start of the income year.
• Replace personal financial advice.

It provides an estimate only.

Eligibility depends on your full circumstances.

How the tax offset works

If your spouse earns:

• $37,000 or less, you may receive the full $540 offset if you contribute at least $3,000.
• Between $37,000 and $40,000, the offset reduces gradually.
• $40,000 or more, no offset applies.

For example:

If your spouse earns $38,000:

• That is $1,000 above the lower threshold.
• The maximum eligible contribution amount reduces from $3,000 to $2,000.
• 18% of $2,000 equals a $360 offset.

The calculator automates this calculation.

When does the offset apply?

The spouse contribution must:

• Be made to a complying super fund.
• Be a non deductible contribution.
• Be received by the fund during the income year, typically by 30 June for that financial year.
• Be made while both spouses are Australian residents.
• Be made while you are not living separately and apart on a permanent basis.

Contribution splitting does not qualify.

Should you contribute exactly $3,000?

Not necessarily.

Contributing $3,000 makes sense only if:

• Your spouse earns $37,000 or less, or close to it.
• They have not exceeded their non concessional cap for the year.
• Their total super balance allows further contributions.
• You have the cash flow.

If your spouse earns closer to $40,000, the maximum effective contribution reduces.

The calculator shows you the effective amount based on income.

Common mistakes when using this calculator

• Using taxable income instead of the correct income definition.
• Assuming the offset applies automatically without claiming it at T3.
• Confusing spouse contributions with contribution splitting.
• Forgetting the contribution must be non deductible.
• Leaving it too late in June and missing the fund’s cut off for processing.

---

Is it worth doing?

For some couples, a $540 tax offset for contributing $3,000 can be attractive.

For others, cash flow or contribution cap considerations may matter more.

The offset reduces your tax payable. It does not get paid into super.

FAQs

How much is the spouse super tax offset?

The maximum tax offset is $540. It is calculated as 18% of the lesser of $3,000 minus any amount your spouse’s income exceeds $37,000, or the total spouse contribution you made during the income year.

At what income does the spouse tax offset phase out?

The tax offset begins to reduce once your spouse’s income exceeds $37,000 and phases out completely when their income reaches $40,000.

Does contribution splitting qualify for the $540 offset?

No. Contribution splitting is a rollover of concessional contributions and does not qualify for the spouse super tax offset.
