Superannuation tax is often summed up in one sentence: your super is taxed at 15%. That sounds simple. It is also incomplete.

Tax can apply when money enters your super fund, while the fund invests it and when you eventually take it out. The rate at each stage depends on the type of contribution, your income, your age, the tax components in your account and the size of your total super balance.

Used carefully, super can reduce the amount of tax you pay while you are working. There is a trade-off, though. Money placed in super is generally locked away until you meet a legal condition of release.

General information only: This article does not consider every tax rule, income test or personal circumstance. Contribution caps and thresholds can change. Check the current Australian Taxation Office guidance or speak with a registered tax agent or licensed financial adviser before making a large contribution.

Super tax applies at three different points

The easiest way to understand the system is to separate it into three stages.

Stage	What may be taxed	Usual treatment
Money going in	Employer, salary-sacrifice and deductible personal contributions	Usually taxed at 15% inside the fund
Money being invested	Interest, dividends, rent and capital gains	Generally taxed at up to 15% in an accumulation account
Money coming out	Lump sums and income-stream payments	Often tax-free from age 60 when paid from a taxed fund, although exceptions apply

The word “usually” matters. High-income earners may pay extra tax on contributions. People with very large super balances face separate rules from 1 July 2026. Withdrawals from untaxed funds and some defined benefit pensions can also be taxed differently.

Tax on employer super contributions

Most employees receive compulsory employer contributions under the super guarantee system. The super guarantee rate is 12% of qualifying earnings in 2026–27.

Employer contributions are concessional contributions. Your fund normally deducts 15% contributions tax when the money arrives.

Suppose your employer pays $1,000 into your account. After 15% contributions tax, about $850 remains available for investment.

That tax is paid from your super account. It does not normally appear as an extra amount on your personal income tax return.

Your employer’s contributions count towards your annual concessional contributions cap. This catches people who assume the cap applies only to voluntary payments.

What counts as a concessional contribution?

Concessional contributions are amounts that receive concessional tax treatment when they enter super. They commonly include:

Compulsory super guarantee payments made by your employer.
Extra employer contributions.
Salary-sacrifice contributions.
Personal contributions for which you claim a tax deduction.
Certain government-funded super contributions, including eligible paid parental leave super payments.

The concessional contributions cap for 2026–27 is $32,500.

The cap applies across all your super funds combined. Opening a second account does not give you a second cap.

Contributions count in the financial year in which the super fund receives them. A payment listed on a June payslip may count in July if it reaches the fund after 30 June.

You can check current contribution caps on the ATO contributions caps page.

How salary sacrifice can reduce tax

Salary sacrifice means asking your employer to direct part of your future pre-tax salary into super.

The contribution is generally taxed at 15% in the fund instead of being paid to you and taxed at your marginal income tax rate. The arrangement must relate to salary you have not already earned.

Here is a basic example.

Assume you are in the 30% personal income-tax bracket and pay the standard 2% Medicare levy. If you receive an extra $1,000 as salary, you may keep about $680 after those taxes, ignoring offsets and other adjustments.

If the same $1,000 goes into super through salary sacrifice, about $850 may remain after 15% contributions tax.

In this simplified example, $170 more is invested for retirement.

That does not make salary sacrifice the right answer for every spare dollar. The money is generally inaccessible until you meet a condition of release. You may need cash for debt repayments, an emergency fund, housing costs or other near-term expenses.

Salary sacrifice contributions also count towards the $32,500 concessional cap, along with your employer’s compulsory payments. Check how much has already gone into your account before choosing an amount.

The ATO explains the arrangement in its salary-sacrifice guidance.

Claiming a tax deduction for personal super contributions

You do not need a workplace salary-sacrifice arrangement to make a concessional contribution.

You can transfer money from your bank account into super and may then claim a personal tax deduction. Once the deduction is validly claimed, the contribution is treated as concessional and usually attracts 15% contributions tax inside the fund.

There is an administrative step that cannot be skipped. You generally need to give your fund a valid notice of intent to claim a deduction and receive its written acknowledgement.

Do this before lodging your tax return. You may also lose the ability to claim the deduction if you roll the full balance to another fund, withdraw the money or start a pension before submitting the notice.

Keep the fund’s acknowledgement with your tax records. A bank receipt alone is not enough to prove that the notice requirements were met.

Personal deductible contributions count towards the same concessional cap as employer and salary-sacrifice payments.

Using unused concessional cap amounts

Some people can contribute more than the standard annual cap by using unused concessional cap amounts from earlier years.

You may qualify when your total super balance was below $500,000 at the previous 30 June. Eligible unused amounts can generally be carried forward for up to five years.

This can help after a career break, a period of part-time work or a year in which your income rises unexpectedly. It may also be useful when selling an investment or receiving a bonus, although the contribution still needs to meet the tax rules.

Do not estimate your unused amount from memory. Log in to ATO online services through myGov and check the concessional contributions information recorded against you.

Recent contributions may not appear immediately. Compare the ATO figure with your fund transactions before making a large end-of-year payment.

Division 293 tax for higher-income earners

The standard 15% contributions tax does not always apply on its own.

Division 293 can impose another 15% tax when your income for Division 293 purposes, plus relevant concessional contributions, exceeds $250,000.

The extra tax applies to the lesser of:

Your concessional contributions for Division 293 purposes.
The amount by which your income and those contributions exceed the $250,000 threshold.

This can bring the total tax on the affected contributions to 30%.

Even at 30%, super may still receive better tax treatment than salary taxed at the highest personal rates. The calculation is personal, though, and the Division 293 income definition includes more than ordinary taxable salary.

The ATO usually issues a Division 293 assessment after processing your tax return and receiving contribution information from your fund. You can pay it personally or, within the allowed period, elect to release money from super.

Read the current rules on the ATO Division 293 page.

What happens when you exceed the concessional cap?

Going over the cap does not mean the whole contribution is confiscated. It can still produce an unexpected tax bill.

Excess concessional contributions are generally included in your assessable income and taxed at your marginal rate. You receive a tax offset for the 15% already paid by the fund.

You may be allowed to release part of the excess amount from super to help pay the resulting liability.

An amount left in the fund can also count towards your non-concessional contributions cap. That creates a second problem if you have already used most of that cap.

Before adding money near 30 June, include employer payments that have not yet appeared in your account. Payroll timing is one of the easiest ways to go over by accident.

Non-concessional contributions use after-tax money

Non-concessional contributions are personal payments made from money on which you have already paid income tax. You do not claim a deduction for them.

Because the money is after-tax, your fund does not normally deduct the 15% contributions tax when it arrives.

The non-concessional contributions cap for 2026–27 is $130,000.

Your ability to use the cap depends on your total super balance at the previous 30 June. If that balance is too high, your non-concessional cap may be reduced to nil.

Eligible people may be able to use the bring-forward arrangement and contribute up to several years of cap space at once. For 2026–27, this can allow contributions of up to $390,000 over a three-year period, depending on your total super balance and any bring-forward arrangement already in progress.

Do not assume the full $390,000 is available. The thresholds change when contribution caps and the general transfer balance cap are indexed.

The ATO’s non-concessional contributions guide contains the current balance thresholds.

Tax on investment earnings inside super

Once money is in an accumulation account, the fund invests it. Tax can apply to interest, dividends, rent and realised capital gains.

A complying super fund generally pays tax on investment earnings at a rate of up to 15%.

Capital gains on assets held for at least 12 months may qualify for a one-third discount. That can reduce the effective tax rate on the discounted capital gain to 10%.

The actual tax deducted from your account may not look like a neat 15% calculation. Funds can receive franking credits, claim deductions and offset gains against losses. Large pooled funds also build tax provisions into unit prices or crediting rates.

Your investment return is normally reported after investment tax has been taken into account. Check the fund’s annual statement or product disclosure documents to see how returns are presented.

What changes when you start a retirement pension?

Investment earnings on money supporting a retirement-phase income stream are generally exempt from tax inside the fund.

You cannot transfer an unlimited amount into the tax-exempt retirement phase. The general transfer balance cap is $2.1 million from 1 July 2026.

Your personal transfer balance cap may be lower than the general cap if you started a retirement-phase pension before that date. Indexation is proportional for people who have previously used part of their cap.

Money above your available personal cap usually needs to remain in an accumulation account or be withdrawn from super. Earnings on the accumulation portion continue to be taxed under the normal fund rules.

A transition-to-retirement income stream does not automatically receive the same earnings-tax exemption as a retirement-phase pension. The account generally needs to enter retirement phase before the exemption applies.

Check your personal cap through ATO online services and read the ATO transfer balance cap guidance.

Division 296 tax on large super balances

A separate tax regime began on 1 July 2026 for people with large total super balances.

For 2026–27, the large super balance threshold is $3 million. Division 296 applies an additional 15% tax to the proportion of eligible earnings attributable to balances above that threshold.

A second threshold applies at $10 million. A further 10% tax can apply to the proportion of earnings attributable to balances above that amount.

The thresholds apply to your total super balance across your accounts, not to each account separately.

Division 296 is assessed to the individual rather than being part of the ordinary tax return lodged by the super fund. The rules contain separate calculations for contributions, withdrawals, defined benefit interests and realised earnings.

People near either threshold should obtain advice before moving assets, starting pensions or making large contributions. The ATO explains the new system on its Division 296 page.

Is super tax-free after age 60?

For many people, benefits paid after age 60 from a taxed super fund are tax-free.

This commonly covers lump-sum withdrawals and account-based pension payments from large retail, industry and public-offer funds.

There are exceptions. Untaxed public-sector schemes, some defined benefit income streams and death benefits can receive different treatment.

Reaching age 60 does not always mean you can withdraw the entire account immediately. You still need to meet a condition of release.

You can generally access super:

After reaching age 60 and retiring.
After reaching age 60 and ending an employment arrangement.
At age 65, even if you continue working.
Under one of the limited early-release provisions.

For most people now approaching retirement, preservation age is 60.

Tax on withdrawals before age 60

Withdrawals before age 60 may contain a tax-free component and a taxable component.

The tax-free component usually comes from non-concessional contributions and certain other amounts. It is generally paid tax-free.

The taxable component may be taxed, depending on your age, the type of fund and how the benefit is paid.

People who have reached preservation age but are under 60 may receive concessional treatment on some lump-sum benefits. Income-stream payments can be included in assessable income, sometimes with a tax offset.

Early access on severe financial hardship or compassionate grounds does not automatically make the payment tax-free. The ordinary super benefit tax rules can still apply.

Ask the fund for an estimate of the tax components and withholding before requesting a withdrawal.

Government payments and offsets that can add to your super

Tax concessions are not limited to people on high salaries.

Low income super tax offset

If you earn $37,000 or less and meet the conditions, the low income super tax offset may return up to $500 of contributions tax to your super account.

You do not normally apply for it. The ATO calculates the amount after your tax return is lodged and your fund reports its contribution information.

From 1 July 2027, legislated changes are scheduled to increase the income threshold to $45,000 and the maximum payment to $810.

Government co-contribution

Eligible low- and middle-income earners who make an after-tax personal contribution may receive a government co-contribution of up to $500.

A contribution claimed as a tax deduction does not qualify as an after-tax contribution for this purpose.

The income thresholds are indexed, so check the current ATO table before deciding how much to contribute.

Spouse contribution tax offset

You may be able to claim a tax offset of up to $540 when you contribute to the super account of a low-income or non-working spouse.

The full offset generally requires an eligible contribution of at least $3,000 and spouse income of $37,000 or less. The offset reduces as the spouse’s income approaches $40,000.

Separate conditions apply to both partners, including total super balance and age rules.

Common super tax myths

“Every dollar in super is taxed at 15%”

No. Concessional contributions are usually taxed at 15%, but non-concessional contributions are not taxed again on entry. Earnings, withdrawals and high-balance taxes have their own rules.

“Salary sacrifice does not count towards my cap”

It does. Salary sacrifice, employer super and deductible personal contributions all use the concessional cap.

“I can claim a deduction after moving the money to another fund”

Possibly not. You generally need to submit a valid notice of intent before rolling over, withdrawing or starting a pension with the contribution.

“Super is always better than investing outside super”

Super often receives lower tax rates, but access is restricted. An investment held outside super may suit money needed before retirement. Fees, investment choices and personal tax rates also affect the comparison.

“All super withdrawals are tax-free after 60”

Many payments from taxed funds are tax-free after 60. Untaxed schemes, defined benefit pensions and some death benefits can be treated differently.

“Opening several funds gives me several contribution caps”

No. Contribution caps apply to you across all funds combined.

Simple checks that may prevent an avoidable tax bill

Confirm how much your employer has already contributed this financial year.
Check contributions in every super account, not only your main fund.
Use ATO online services to view available carry-forward amounts.
Allow for contributions that are still being processed.
Submit a notice of intent before lodging a deduction claim.
Check your total super balance before making an after-tax contribution.
Review Division 293 exposure when income is near $250,000.
Check your personal transfer balance cap before starting or adding to a pension.
Give your tax file number to the fund so additional tax is not deducted unnecessarily.
Keep acknowledgements, contribution receipts and fund statements with your tax records.

Keeping more does not mean avoiding tax altogether

Super works well as a tax concession because the usual contribution and investment tax rates are lower than many personal income-tax rates.

The benefit comes with boundaries. Annual caps limit how much can receive concessional treatment. Access rules keep the money inside the retirement system. Extra taxes can apply to higher incomes and large balances.

Start with the purpose of the money. If it is genuinely for retirement, concessional contributions may leave more invested than taking the same amount as salary. If you may need the money next year, the tax saving may not compensate for losing access to it.

Check the numbers before 30 June rather than after it. Once a contribution reaches the fund, fixing an error can be slow and, in some cases, impossible without an ATO determination.
