How Superannuation Tax Works in Australia: Contributions, Earnings and Withdrawals Explained (2026)
Superannuation is the most tax-advantaged savings vehicle in Australia — but only if you understand the rules. Super is taxed at three separate stages: when money goes in (contributions), while it's growing (earnings), and when it comes out (withdrawals). Each stage has different rates, caps and traps. This guide walks through every layer with real dollar examples so you can see exactly how the numbers work.
This guide is general information only and does not constitute financial advice. Consider your own circumstances and seek professional advice before making financial decisions.
Stage 1 — Tax on Contributions (Money Going In)
There are two types of contributions and they're taxed completely differently.
Concessional (Before-Tax) Contributions
Concessional contributions include employer Super Guarantee (SG), salary sacrifice, and personal contributions you claim as a tax deduction. They enter your fund from pre-tax income and are taxed at a flat 15% inside the fund — well below most people's marginal tax rate.
The annual concessional cap for 2025–26 is $30,000.
Worked example: concessional contribution tax
James earns $100,000. His employer contributes 11.5% SG = $11,500. He salary-sacrifices an additional $10,000.
- Total concessional contributions: $21,500
- 15% contributions tax: $21,500 × 0.15 = $3,225
- Net amount credited to his super account: $18,275
Without the salary sacrifice, that $10,000 would have been taxed at his 32.5% marginal rate (plus 2% Medicare Levy) = $3,450 in tax. Inside super it costs $1,500 in tax. Saving: $1,950.
What Happens If You Exceed the Concessional Cap?
Contributions over the $30,000 cap are added to your assessable income and taxed at your marginal rate — on top of the 15% already paid inside the fund. You'll receive an excess concessional contributions determination from the ATO. You can elect to release the excess from your fund or pay the additional tax from your own savings. The ATO also charges an interest charge (called the Excess Concessional Contributions Charge) on the extra tax from the start of the financial year until you lodge your return.
Non-Concessional (After-Tax) Contributions
Non-concessional contributions are made from after-tax income. Because you've already paid income tax on this money, they enter your fund tax-free — no 15% contributions tax applies.
The annual non-concessional cap for 2025–26 is $120,000. If you're under 75, you can use the bring-forward rule to contribute up to $360,000 in a single year (three years' worth at once). The bring-forward is only available if your total super balance is under $1.9 million at 30 June of the previous year.
Warning: exceeding the non-concessional cap
Excess non-concessional contributions are taxed at 47% (top marginal rate plus Medicare Levy) unless you elect to withdraw the excess and associated earnings from your fund within 60 days of the ATO determination. The earnings on the excess are taxed at your marginal rate. This is one of the most expensive tax mistakes you can make — always track your cap carefully.
Division 293 Tax — The Extra 15% for High Earners
If your income plus concessional contributions exceeds $250,000, you pay an additional 15% tax on the concessional contributions that push you over the threshold. This brings the effective contributions tax rate to 30% — still below the top marginal rate of 45%.
Worked example: Division 293
Sophie earns $260,000. Her employer contributes $29,900 in SG. Her income plus super = $289,900.
- Amount over $250,000 threshold: $289,900 − $250,000 = $39,900
- Division 293 applies to the lesser of the excess ($39,900) and total concessional contributions ($29,900) = $29,900
- Extra tax: $29,900 × 15% = $4,485
Sophie can elect to pay the $4,485 from her super fund or from personal savings. Most people release it from super.
Stage 2 — Tax on Earnings (Money Growing Inside Super)
Investment returns inside super — interest, dividends, rent, and realised capital gains — are taxed at a maximum of 15% during the accumulation phase (while you're still working and building your balance).
Capital Gains Inside Super
Assets held inside super for more than 12 months receive a one-third CGT discount, reducing the effective tax rate on those gains from 15% to 10%. Compare that to the personal CGT rate of up to 23.5% (after the 50% individual discount) outside super.
| Scenario | Tax Rate on Earnings |
|---|---|
| Interest, dividends, rent (accumulation phase) | 15% |
| Capital gains on assets held 12+ months (accumulation) | 10% (after 1/3 discount) |
| Capital gains on assets held under 12 months (accumulation) | 15% |
| All earnings in retirement phase (pension) | 0% |
Franking Credits Inside Super
Super funds receive franking credits from Australian company dividends, just like individual shareholders. Because the fund's tax rate is 15% and companies pay 30% tax before distributing dividends, the fund gets a refund of the excess franking credits. This effectively boosts after-tax returns on Australian shares inside super.
Worked example: earnings tax inside vs outside super
$200,000 invested in an Australian share fund returning 7% ($14,000) per year:
- Outside super (37% marginal rate + 2% Medicare Levy): tax on $14,000 = $5,460. After-tax return: $8,540.
- Inside super (accumulation): tax on $14,000 at 15% = $2,100, minus franking credit refund ≈ $900 = $1,200 effective tax. After-tax return: $12,800.
- Inside super (retirement pension): tax = $0. After-tax return: $14,000.
The Transfer Balance Cap
When you move money from the accumulation phase into a tax-free retirement pension, there's a limit on how much you can transfer. The general transfer balance cap for 2025–26 is $1.9 million. Any amount above this stays in the accumulation phase and continues to be taxed at 15%.
The cap is a lifetime limit, not annual. If you start a pension, it counts against your cap. If you commute (reverse) part of it and later restart, the amount is tracked via your personal transfer balance account.
Stage 3 — Tax on Withdrawals (Money Coming Out)
The tax on super withdrawals depends on your age, whether you've met a condition of release, and the components of your super balance (tax-free vs taxable).
Tax-Free vs Taxable Components
Your super balance is made up of two components:
- Tax-free component — non-concessional contributions and certain other amounts (e.g. government co-contributions). These are always withdrawn tax-free regardless of your age.
- Taxable component — concessional contributions and investment earnings. The tax treatment depends on your age when you withdraw.
| Your Age | Tax-Free Component | Taxable Component |
|---|---|---|
| 60 and over (met condition of release) | Tax-free | Tax-free |
| Preservation age (57–59) to 59 | Tax-free | First $235,000 tax-free (low rate cap), remainder at marginal rate |
| Under preservation age | Tax-free | Marginal rate + 2% Medicare Levy |
Worked example: withdrawal at age 62
Linda retires at 62 with $600,000 in super — $120,000 tax-free component and $480,000 taxable component.
- Tax-free component: $120,000 — $0 tax
- Taxable component: $480,000 — $0 tax (she's over 60)
- Total tax on withdrawal: $0
If she starts an account-based pension, all ongoing earnings and pension payments are also tax-free (up to the transfer balance cap).
Worked example: early withdrawal at age 45 (hardship or other condition)
Mark accesses $30,000 on compassionate grounds at age 45. His super is 10% tax-free component and 90% taxable component.
- Tax-free portion: $30,000 × 10% = $3,000 — $0 tax
- Taxable portion: $30,000 × 90% = $27,000
- Tax on taxable portion (at marginal rate, say 32.5% + 2% ML): $27,000 × 34.5% = $9,315
Early access is expensive. The tax hit plus the loss of decades of compounding makes it a last resort.
Death Benefits — Tax on Super Paid to Your Estate
If you die, your super isn't automatically part of your estate. It's paid out as a death benefit, and the tax treatment depends on who receives it:
- Tax dependants (spouse, child under 18, financial dependant): the entire benefit — both tax-free and taxable components — is received tax-free.
- Non-dependants (adult children, other beneficiaries): the tax-free component is tax-free, but the taxable component is taxed at 15% (plus 2% Medicare Levy = 17%).
Why this matters: the death benefit trap
A single person with $800,000 in super (10% tax-free, 90% taxable) who dies and leaves their super to an adult child:
- Tax-free component: $80,000 — $0 tax
- Taxable component: $720,000 × 17% = $122,400 tax
This is why estate planning around super — including binding death benefit nominations and insurance structuring — is critical. A financial adviser can help you minimise the tax hit on your beneficiaries.
The Full Picture: Total Tax on $1 Through Super vs Outside Super
The real power of super becomes clear when you trace a single dollar through the entire system.
| Step | Inside Super (Concessional) | Outside Super |
|---|---|---|
| Gross income | $1.00 | $1.00 |
| Tax on contribution/income (37% marginal rate example) | −$0.15 (15% contributions tax) | −$0.39 (37% + 2% ML) |
| Amount invested | $0.85 | $0.61 |
| Annual earnings tax (on 7% return) | ~10–15% | Up to 39% |
| Tax on withdrawal (age 60+) | 0% | N/A (already taxed) |
At a 37% marginal rate, you start with 39% more capital inside super ($0.85 vs $0.61). That gap compounds every year because earnings are also taxed at a lower rate. Over 20–30 years, the difference is enormous.
Common Tax Mistakes With Super
Mistakes that cost people real money
1. Forgetting the Notice of Intent for personal deductible contributions
If you make a personal contribution and don't lodge the Section 290-170 form with your fund before lodging your tax return, the contribution is treated as non-concessional. You get no tax deduction, and you may accidentally breach the non-concessional cap.
2. Not knowing your employer SG counts towards the $30,000 cap
Your employer's 11.5% SG contributions count toward the $30,000 concessional cap. If you earn $120,000, your employer contributes $13,800 — leaving $16,200 of cap space, not $30,000. Exceeding the cap triggers excess contributions tax at your marginal rate.
3. Ignoring the Division 293 assessment
If you earn over $250,000 (including super), you'll receive a Division 293 tax notice. Ignoring it doesn't make it go away — the ATO will chase it. Elect to pay from super early so your personal cash flow isn't disrupted.
4. Not updating your death benefit nomination
If you don't have a valid binding nomination, the fund trustee decides who gets your super — and they may distribute it to non-dependants, triggering a 17% tax bill that could have been avoided. Review your nomination every three years (most binding nominations expire after three years unless your fund offers non-lapsing nominations).
5. Assuming all super withdrawals after 60 are tax-free
Lump sum withdrawals from a taxed fund after age 60 are tax-free. But if any portion of your super came from an untaxed source (some public sector and defined benefit funds), the untaxed element is taxed at up to 17% on withdrawal. Check your fund's annual statement for "untaxed" components.
Smart Tax Strategies Within the Rules
1. Max Out Concessional Contributions (Especially at Higher Marginal Rates)
The tax saving from concessional contributions increases with your marginal rate. At the 45% bracket ($190,001+), every dollar salary sacrificed into super saves 30 cents in tax (45% + 2% ML minus 15% contributions tax). At the 30% bracket ($135,001–$190,000), it saves 17 cents.
2. Use Catch-Up Contributions If You Have Unused Cap Space
If your total super balance is under $500,000, you can carry forward unused concessional cap amounts from the previous five financial years. This is particularly valuable after a career break, parental leave, or years when employer SG was your only contribution.
Worked example: catch-up contributions
Priya took three years of parental leave (2021–22, 2022–23, 2023–24) and only received employer SG of $8,000 per year during that time. She's now back at work earning $130,000.
- Unused cap per year during leave: $27,500 − $8,000 = $19,500 (the cap was $27,500 before 2024–25)
- Three years of unused cap: $19,500 × 3 = $58,500
- Plus current year cap: $30,000
- Total available concessional space: $88,500
If Priya contributes $50,000 this year (after SG), she'd save approximately $8,750 in tax compared to receiving that money as salary at her marginal rate.
3. Split Contributions With Your Spouse
You can split up to 85% of your concessional contributions to your spouse's super fund. This doesn't save income tax directly, but it can help equalise super balances — which means both partners can maximise the $1.9 million transfer balance cap and reduce potential death benefit tax.
4. Contribute to Your Low-Income Spouse's Super
If your spouse earns less than $40,000, you can make a non-concessional contribution to their super and receive a tax offset of up to $540 per year. The maximum offset applies when you contribute $3,000 and your spouse earns $37,000 or less.
5. Time Large Capital Gains With Super Contributions
If you're selling a property or large parcel of shares, making a large concessional contribution in the same financial year can push your taxable income down a bracket — reducing the marginal rate applied to the capital gain. Combine this with catch-up contributions for maximum effect.

Frequently Asked Questions
Is super really worth it if I can't access it until I'm 60?
Yes — if you're comparing like-for-like. The tax savings mean you start with more capital and it grows faster. A 30-year-old contributing $10,000 per year to super instead of investing the after-tax equivalent outside super will have roughly 40–60% more at retirement, depending on their marginal rate and investment returns. The trade-off is liquidity — you can't touch it early (except in limited hardship situations).
Do I pay tax on super pension payments after 60?
No — pension payments from a taxed super fund after age 60 are completely tax-free. You don't even need to include them on your tax return (though your fund reports them to the ATO). The only exception is if your fund has an "untaxed" element, which mainly applies to some public sector defined benefit schemes.
What is the difference between a taxed and untaxed super fund?
Most super funds in Australia are "taxed" funds — they pay 15% tax on contributions and earnings as they go. Some public sector and defined benefit funds are "untaxed" — they defer the tax until the benefit is paid out. If you're in an untaxed fund, your withdrawal tax treatment is different (and generally less favourable). Check your annual statement or call your fund to confirm.
Can I contribute to super if I'm not working?
Yes. There is no work test for contributions if you're under 75. You can make both concessional and non-concessional contributions regardless of employment status. To claim a tax deduction on concessional contributions, you need to lodge a Notice of Intent. If you have no taxable income, a deduction may not be beneficial — in that case, non-concessional contributions or the government co-contribution may be more appropriate.
How does super tax compare to other countries?
Australia's super tax system is relatively generous by global standards. The 15% flat rate on contributions and earnings is well below most people's marginal rate, and the 0% rate in retirement is rare internationally. The UK's pension system taxes withdrawals as income; the US 401(k) defers tax but charges full marginal rates on withdrawal. Australia's system effectively taxes at a low flat rate in, a low flat rate during, and zero on the way out — a structure that rewards long-term saving.
The Bottom Line
Super is taxed at three stages — contributions, earnings and withdrawals — and the rates at each stage are significantly lower than personal income tax rates for most Australians. The system rewards those who understand the rules and penalises those who exceed the caps or miss the paperwork.
The most valuable actions for most people:
- Max out concessional contributions (or get as close to $30,000 as you can afford)
- Use catch-up contributions if you have unused cap space from previous years
- Lodge the Notice of Intent if you make personal deductible contributions
- Review your death benefit nomination every three years
- Understand your fund's tax-free vs taxable components so there are no surprises at retirement
Super isn't exciting — but the tax maths is unambiguous. Every dollar that flows through super instead of your personal tax return keeps more of itself. Over 20 or 30 years, that difference compounds into tens or hundreds of thousands of dollars.
