Concessional Super Contributions: 7 Ways to Maximise Tax Benefits

Concessional super contributions can be one of the most effective ways to lower personal tax while accelerating retirement savings for employees, business owners and SMSF members. Whether you contribute through salary sacrifice, personal deductible payments or rely on employer Super Guarantee, a clear plan helps you capture immediate tax benefits and stay compliant. If you want a tailored strategy for your situation, our SMSF team can help you model outcomes and implement contributions correctly across the year.

The rules in plain English

Concessional super contributions are before‑tax amounts paid into super, typically taxed at 15 percent by your fund. They include Super Guarantee from your employer, salary sacrifice, and personal contributions for which you later claim a tax deduction (Australian Taxation Office — Understanding concessional and non‑concessional contributions).

The annual cap for concessional super contributions is $30,000 in 2025–26. All concessional amounts across all your super funds are added together and counted in the financial year your fund receives them, not the day you transfer the money (Australian Taxation Office — Concessional contributions cap).

From 1 July 2025 the Super Guarantee rate is 12 percent, which increases what many workers receive into super during the year (Australian Taxation Office — Super guarantee).

Alongside concessional caps sit after‑tax non‑concessional caps. These are separate and are relevant if you are blending strategies with your spouse or equalising balances. The general non‑concessional cap is $120,000 for 2025–26 and interacts with the general transfer balance cap when determining eligibility to contribute (Australian Taxation Office — Non‑concessional contributions cap).

If your income plus concessional contributions exceeds $250,000, Division 293 adds an extra 15 percent tax on some or all of your concessional super contributions. Even then, the total tax inside super is often below top personal rates, so the after‑tax benefit can remain significant (Australian Taxation Office — Division 293 tax).

Seven strategies to maximise tax benefits

1) Fill your annual cap with purpose

For many Australians, maximising the $30,000 annual limit for concessional super contributions delivers an immediate deduction at their marginal rate while contributions are taxed at 15 percent in the fund. This cap includes employer Super Guarantee, any salary sacrifice arrangements, and personal deductible contributions that you claim via a notice of intent (Australian Taxation Office — Understanding concessional and non‑concessional contributions).

Practical steps
Estimate what your employer will contribute by 30 June, then calculate the gap you can fill with salary sacrifice or a personal deductible contribution without exceeding your cap.

2) Carry forward unused cap amounts for high‑income or high‑gain years

If your total super balance was under $500,000 at the previous 30 June, you may be eligible to use unused concessional cap space from the prior five years. Deployed well, this lets you make larger concessional super contributions in a single year to help manage lumpy income or a large capital gain (Australian Taxation Office — Concessional contributions cap).

Planning tip
Use carry‑forward space in years where your marginal tax rate is highest, while modelling whether Division 293 would apply once you add your intended concessional super contributions (Australian Taxation Office — Division 293 tax).

3) Choose the right route: salary sacrifice or personal deductible contribution

Salary sacrifice directs future pre‑tax salary into super. A personal deductible contribution is paid from after‑tax cash and then claimed with a valid notice of intent acknowledged by your fund. Both count toward your cap and both are concessional super contributions (Australian Taxation Office — Understanding concessional and non‑concessional contributions).

If you are between 67 and 74 and wish to claim a deduction for a personal contribution made after turning 67, you must meet the work test in the financial year of contribution or qualify for the one‑off work test exemption for recent retirees.

Documentation tip
You can only claim the deduction if your notice of intent is lodged and the fund issues an acknowledgement before you lodge your tax return for the relevant year. Keep these records with your tax file.

If you want a clean set of trustee minutes and deduction notices prepared for your SMSF, we can bundle this for you.

4) Get the timing right so contributions land before 30 June

Contributions count in the year your fund receives them. Payments made near the end of June can miss 30 June due to clearing houses, bank processing or internal fund cut‑offs. Plan early so your concessional super contributions are credited before year end (Australian Taxation Office — Concessional contributions cap).

Employers must also ensure Super Guarantee contributions reach an employee’s fund by the quarterly due dates to avoid the Super Guarantee Charge. The June quarter due date is 28 July (Australian Taxation Office — Super payment due dates).

5) Manage Division 293 if your income is near or above $250,000

Division 293 adds an extra 15 percent tax to some or all concessional super contributions when your income plus concessional contributions exceeds $250,000. The ATO issues a Division 293 assessment after it receives both your tax return and your fund’s contribution data. You can pay the bill personally or by releasing money from super via an election (Australian Taxation Office — Division 293 tax).

Important nuance
Salary sacrifice reduces taxable income but increases concessional contributions by the same amount, so it usually does not lower your Division 293 “income” calculation. Even with the additional 15 percent, many high‑income earners still benefit from concessional super contributions because the combined 30 percent inside super is typically below their marginal rate.

We can model different contribution sizes to show after‑tax outcomes for your household and advise on paying the assessment from cash flow or by release authority.

6) Split concessional contributions to your spouse to equalise balances

Subject to eligibility and fund rules, you can apply to split up to 85 percent of the previous financial year’s concessional contributions to your spouse’s super. This does not change the original contributor’s cap usage, but it can help equalise balances, improve future access if one spouse is older, or preserve thresholds that support carry‑forward strategies for concessional super contributions (Australian Taxation Office — Contributions splitting for members).

Eligibility usually requires the receiving spouse to be under their preservation age, or between preservation age and 65 and not retired when the split is processed (Australian Taxation Office — Contributions splitting for members).

If you want us to prepare the splitting request and ensure it aligns with your broader plan, we are happy to help.

7) If you are 67–74, meet the work test to claim deductions

Funds can accept most contribution types up to age 75, but if you are 67–74 and wish to claim a deduction for a personal contribution made after you turn 67, you must satisfy the work test in the year of contribution or qualify for the one‑off work test exemption for recent retirees. Time‑critical planning ensures your concessional super contributions remain deductible (Australian Taxation Office — Restrictions on voluntary contributions).

A practical year‑end checklist

• Confirm your year‑to‑date concessional super contributions and any available carry‑forward amounts in ATO online services before adding more. Use this to set your target contribution and avoid excesses.
• Forecast your employer’s Super Guarantee to 30 June so you do not inadvertently exceed the $30,000 cap once you add salary sacrifice and any personal deductible amount.
• If your projected income is near $250,000, model Division 293 before making large concessional super contributions so you understand the after‑tax benefit.
• Make personal contributions by mid‑June and confirm allocation in your super portal so they count this financial year. Employers should diarise the SG due dates, noting the June quarter must be received by 28 July.
• If you are 67–74 and want to claim a deduction, ensure you meet the work test or qualify for the exemption and keep evidence. Lodge your notice of intent and wait for the acknowledgement before lodging your tax return.
• If you operate an SMSF, ensure contributions are received by the SMSF bank account before 30 June and are allocated in your records correctly, especially where carry‑forward concessional super contributions are involved.

Common pitfalls to avoid

• Waiting until the last banking day of June. Contributions only count when the fund receives them, and clearing houses or internal processing can push them into July. Align payment dates so your concessional super contributions land in time.
• Forgetting to account for employer Super Guarantee when calculating your remaining concessional cap. This can cause accidental excess contributions.
• Assuming salary sacrifice avoids Division 293. It typically leaves your Division 293 “income” unchanged because the reduction in taxable income is offset by higher concessional contributions. Even so, concessional super contributions can still be beneficial after tax.
• Lodging a tax return before your notice of intent is acknowledged by the fund. Without a valid acknowledgement, your personal contribution will not be deductible.
• Skipping documentation in an SMSF. Trustees need clear records of contribution receipt and allocation, particularly where carry‑forward concessional super contributions are used.

The current rules give Australians meaningful options to reduce tax and build wealth through concessional super contributions. With a $30,000 annual cap, five‑year carry‑forward availability for eligible members, and spouse splitting to balance accounts, a well‑timed plan can materially improve your after‑tax position while supporting retirement goals.
