Superannuation has tax applied at three separate points, and mixing them up is the most common reason people misread their balance. This article explains that mechanics chain — money going in, earnings while it is invested, and money coming out — using only the published positions of Moneysmart and the Australian Taxation Office (ATO). It does not recommend contribution amounts, funds or strategies, and nothing here is personal advice.
The three points where tax applies
Moneysmart (moneysmart.gov.au) sets super tax out as three separate stages:
- Contributions going in — your employer pays money into your super and your fund taxes most of these contributions at 15%.
- Investment earnings — your fund invests the money, and the fund pays tax on the earnings from those investments.
- Withdrawals coming out — how much tax you pay depends on the taxable, tax-free and untaxed components of your super.
The practical takeaway: the tax is mostly handled inside the fund, not by you at tax time. You generally do not "pay" contributions tax as a separate bill; it is deducted before the money is credited to your member balance. That is also why two people with similar take-home pay can have noticeably different super outcomes, depending on how much of their pay is packaged as super.
Concessional (before-tax) contributions
The ATO asks you to understand which contributions are before-tax or after-tax, because the rules diverge sharply.
Concessional contributions are the before-tax side. In practice this bucket covers the money your employer pays in under super guarantee arrangements, plus amounts you arrange to go in before tax, such as salary sacrifice. The defining feature is that the contribution has not yet been taxed as your income.
Per Moneysmart, your super fund taxes most employer contributions at 15%. The ATO's page is the reference point for the current concessional cap, because caps are indexed and change over time. Exceeding a cap has consequences, which is why the cap — not the headline tax rate — is the number readers most often need to check first.
One nuance worth flagging: personal contributions you make from your own bank account can sometimes be treated as before-tax if you claim a tax deduction for them. Moneysmart points readers to the ATO page for claiming a deduction on personal contributions. Whether a deduction is available to you, and how it must be documented, depends on your circumstances and on ATO rules that sit outside this explainer.
Non-concessional (after-tax) contributions
Non-concessional contributions are made from money that has already been taxed as your income. The ATO's guidance is direct on the headline point: non-concessional (after-tax) contributions are not taxed unless you exceed the cap.
That asymmetry explains most of the confusion. Before-tax money is taxed on the way in; after-tax money generally is not. The obligation on you is record-keeping: the ATO specifically says to keep track of your non-concessional contributions, because the only time they attract contributions tax is when the cap is exceeded. If you make ad-hoc payments from salary savings, inherited money or the proceeds of an asset sale, track them yourself rather than assuming your fund has done it.
| Contribution type | Usual source | Taxed on the way in? | What to check |
|---|---|---|---|
| Employer contributions | Employer, under super guarantee | Yes — most taxed at 15% in the fund (Moneysmart) | Whether any employer amounts sit outside this treatment |
| Salary sacrifice | Your pre-tax salary, arranged with your employer | Treated as before-tax | How it interacts with your concessional cap |
| Personal, deductible claimed | Your own money, deduction claimed | Treated as before-tax | ATO rules on claiming the deduction |
| Personal, no deduction | Your own money after tax | No, unless the cap is exceeded (ATO) | Running total of non-concessional contributions |
Caps, and Division 293 tax
Both sources point to caps and limits as the controlling variable, not preferences. The ATO page covers caps and limits on super contributions and how they are taxed, including caps that apply to defined benefit funds and constitutionally protected (CPF) funds. If you are a member of either type, do not assume the standard accumulation-style treatment applies to you.
The ATO also flags a specific extra tax. The published trigger is: if your income and concessional super contributions total more than $250,000, check whether you have to pay Division 293 tax. This is the one threshold quoted in this article, and it comes straight from the ATO page. "Income" here is a defined concept in ATO material — how your particular income is measured for this test is exactly the kind of detail you should confirm on the ATO page rather than assume.
The ATO page also refers to Division 296 tax. This article does not attempt to set out its operation, rates or commencement, because those details are not covered in the supplied reference material. Treat it as a topic to look up directly on the ATO site if it may affect you.
How contributions show up in records
"Reporting" in super usually means three things, and only the first is truly yours to manage:
- What your employer does — compulsory and salary-sacrificed amounts should appear on your payslip and be paid to the fund.
- What your fund records — contributions and the tax deducted from them should appear in your transaction history and annual statement. Reconciling your payslip against what the fund received is the single most useful check you can run.
- What reaches the ATO — the ATO holds records relating to your contributions and caps. The ATO's own page is the authority on what flows to it and when.
Two habits follow from this. First, check that the tax your fund deducted matches the contribution type you believe you made — a mislabelled personal contribution changes which cap it counts against. Second, keep your own running total of non-concessional contributions across all your funds; if you have had more than one job, more than one fund is likely, and each fund only sees its own slice.
Questions you should put to the sources
- What is the current concessional cap and non-concessional cap, in dollars, this financial year? (ATO)
- Do defined benefit or constitutionally protected fund caps apply to me instead? (ATO)
- Does my income plus concessional contributions total exceed $250,000, on the ATO's definition of income? (ATO)
- Am I entitled to claim a deduction for a personal contribution, and what must I do before or by when? (ATO)
- What are the taxable, tax-free and untaxed components of my balance, and how will they be taxed when I withdraw? (Moneysmart)
Next step
Open your most recent fund statement and your last payslip side by side. Write down three numbers: concessional contributions this financial year, non-concessional contributions this financial year, and your income figure for Division 293 purposes. Then check those numbers against the ATO's "Caps, limits and tax on super contributions" page for current rates and thresholds, and Moneysmart's "Tax and super" page for how each stage is taxed. If your situation involves a defined benefit fund, a constitutionally protected fund, a large balance or a once-off contribution, that combination is the point at which a registered tax agent or financial adviser is the appropriate next call.
