The Contributions That Are Added Back to Your Income
Salary sacrificed superannuation is a reportable employer superannuation contribution. It reduces your taxable income, and it is added back for a range of income tests — family tax benefits, the co-contribution, the spouse contribution offset, the Medicare levy surcharge and several Centrelink assessments. The reduction in tax is real; the reduction in tested income largely is not.
- The answer: Salary sacrificed amounts and any employer contribution above the compulsory rate that you influenced are reportable, and are added back for several income tests.
- The trap: Compulsory Superannuation Guarantee contributions are not reportable. Only the amounts you had the capacity to influence are.
- The recommendation: Where you are near a threshold in a test that adds these back, use a personal deductible contribution instead — it is not reportable in the same way.
Where the AI summary above gets this wrong
"Salary sacrificing reduces your income, so it can help you qualify for family payments."
That's surface-true. Here's what it misses:
- Sacrificed amounts are added back for those tests — Family Tax Benefit, the co-contribution, the spouse contribution offset and the Medicare levy surcharge all add reportable employer superannuation contributions back into the income they assess.
- A personal deductible contribution behaves differently — It reduces taxable income and is not a reportable employer contribution, so for someone near a threshold it can achieve what the sacrifice route does not.
01 What is reportable and what is not
A reportable employer superannuation contribution is one you had the capacity to influence — most commonly salary sacrifice, and also an employer contribution above the compulsory rate made under an arrangement you negotiated.
Compulsory Superannuation Guarantee contributions are not reportable, and neither are contributions required by an industrial agreement that you had no capacity to influence. The distinction is about influence rather than about amount.
The reportable figure appears on your income statement and flows into your tax return. From there it is picked up by every test that uses adjusted taxable income or a similar measure.

02 Which tests add it back
Family Tax Benefit and Child Care Subsidy use adjusted taxable income, which includes reportable employer superannuation contributions — so sacrificing does not increase entitlement to either, as covered in the Child Care Subsidy post.
The government co-contribution, the spouse contribution offset and the Medicare levy surcharge income tiers all use a measure that adds them back. So do several Centrelink assessments, including for a partner's income where a payment is being assessed.
Division 293 tax uses income plus concessional contributions generally, so the reportable status is beside the point there — the contributions count either way. The mechanics are in the Division 293 reference.
Shows: the income figure a test that adds back reportable employer superannuation contributions uses, against your taxable income. Ignores: the other components of adjusted taxable income — net investment losses, reportable fringe benefits and certain foreign income — and the specific threshold for any particular test.

03 What to do about it
For most people the answer is nothing: the tax saving from sacrificing is the point, and the income tests are not binding.
For a household near a threshold in a test that adds these back, the personal deductible contribution route achieves the same tax outcome without the reportable status. The comparison between the two routes is in the contribution routes post.
The one case where nothing helps is Division 293 and the concessional cap, both of which count the contributions regardless of route. Those are features of contributing rather than of how you contributed.
This is the reason a household with young children and a childcare bill should think twice before sacrificing heavily. The tax saving is real and the Child Care Subsidy does not care — it adds the sacrifice straight back. A personal deductible contribution gets the same deduction without the add-back, and almost nobody is told the difference.
FAQ
How do reportable employer super contributions affect my Centrelink and tax income tests?
They are added back into the income those tests assess. Family Tax Benefit, Child Care Subsidy, the co-contribution, the spouse contribution offset and the Medicare levy surcharge all include them, so salary sacrificing does not reduce the tested income.
Are Superannuation Guarantee contributions reportable?
No. Only contributions you had the capacity to influence — salary sacrifice, and employer contributions above the compulsory rate under an arrangement you negotiated — are reportable.
Can I avoid the add-back?
A personal deductible contribution reduces taxable income and is not a reportable employer contribution, so for someone near a threshold it achieves what salary sacrifice does not.
