End of Financial Year Super Strategies Your Complete Guide to Maximising Super Before 30 June 2026

The 30 June Deadline Is Absolute

Every financial year, superannuation contribution caps reset on 1 July. Any unused cap space from the current year (with the exception of carry-forward concessional amounts) is lost permanently. This makes the weeks leading up to 30 June one of the most important windows in the financial planning calendar.

Whether you are an employee looking to reduce your tax bill, a self-employed person seeking a deduction, or a retiree making strategic contributions, the strategies available to you before 30 June 2026 are well-established and can deliver meaningful financial benefits. But they require action, and they require it in time for funds to be received by your super fund before the end of the financial year.

Strategy 1: Maximise Your Concessional Contributions

The concessional contributions cap for 2025-26 is $30,000. This cap includes all concessional contributions: employer Superannuation Guarantee (SG), salary sacrifice contributions, and personal deductible contributions. If you have not yet used your full cap, you have an opportunity to do so before 30 June.

For Employees

Your employer's SG contributions (currently 12% of your ordinary time earnings) count toward the $30,000 cap. If your salary is $100,000, your employer contributes approximately $12,000 in SG over the year, leaving $18,000 of concessional cap space. You can fill this gap through salary sacrifice arrangements or by making personal contributions and claiming a tax deduction.

If you choose to salary sacrifice, speak with your payroll department to increase your salary sacrifice amount for the remaining pay cycles before 30 June. Alternatively, you can make a personal contribution directly to your super fund and submit a Notice of Intent to Claim a Deduction (Section 290-170 form) to your fund before lodging your tax return or before the end of the following financial year, whichever is earlier.

For Self-Employed and Business Owners

Since 1 July 2017, virtually all individuals under age 75 can claim a tax deduction for personal super contributions, regardless of employment status. For self-employed individuals, this is often the most tax-effective strategy available. A $30,000 concessional contribution reduces your taxable income by $30,000 (minus the 15% contributions tax within super), producing an effective tax saving of up to $7,050 for someone in the 45% marginal tax bracket (including Medicare levy).

The Mechanics

1. Check your year-to-date concessional contributions with your super fund
2. Calculate your remaining cap space ($30,000 minus contributions already made)
3. Make a personal contribution to your fund via direct deposit, BPAY, or cheque
4. Submit a valid Notice of Intent to Claim a Deduction to your fund
5. Receive acknowledgement from your fund before lodging your tax return

Strategy 2: Use Carry-Forward (Catch-Up) Contributions

If your Total Superannuation Balance was less than $500,000 at 30 June 2025, you can access unused concessional cap amounts from the previous five financial years. This is known as the carry-forward or catch-up concessional contributions provision.

For example, if you only contributed $15,000 in concessional contributions in the 2021-22 financial year (when the cap was $27,500), you have $12,500 of unused cap space from that year that can be used in 2025-26, in addition to your current year's $30,000 cap. Across five years of accumulated unused amounts, some individuals have well over $100,000 of available concessional cap space.

This strategy is particularly powerful for:

• Parents who took time out of the workforce to raise children
• Self-employed individuals who had lean years with minimal contributions
• People who received a one-off windfall (bonus, inheritance, asset sale) and want to redirect it into super
• Anyone who has recently sold a business and wants to accelerate their super savings

Strategy 3: Spouse Contributions

If your spouse earns less than $40,000 per year in assessable income (including reportable fringe benefits and reportable super contributions), you may be eligible for a tax offset by making a contribution to their super fund. The maximum tax offset is $540 (18% of up to $3,000 contributed) when the spouse's income is $37,000 or less. The offset phases out between $37,000 and $40,000.

This is a non-concessional contribution into your spouse's fund, so it does not affect your concessional cap. It is a straightforward way to build your spouse's super balance while receiving a tax benefit yourself. To qualify, the contribution must be made before 30 June, and your spouse must be under age 75.

Strategy 4: Government Co-Contribution

If your total income is less than $60,400 (for 2025-26), the government will co-contribute to your super when you make after-tax (non-concessional) personal contributions. The maximum co-contribution is $500, paid when you contribute $1,000 and your income is $45,400 or below. The co-contribution reduces for incomes between $45,400 and $60,400.

To be eligible, you must:

• Make a personal non-concessional contribution to your super before 30 June
• Have total income below $60,400
• Have at least 10% of your total income from employment or business
• Lodge your tax return for the relevant year
• Be under age 71 at the end of the financial year

The co-contribution is automatically calculated by the ATO after you lodge your return. No separate application is needed. For low-income earners, this represents a 50% immediate return on up to $1,000, which is difficult to match anywhere else in the financial system.

Strategy 5: Non-Concessional Contributions

If you have already maximised your concessional contributions and have additional savings to deploy, non-concessional (after-tax) contributions offer a way to get more money into the super system. The non-concessional cap for 2025-26 is $120,000, and if you are under 75 and your Total Superannuation Balance is below $1.9 million, you may be able to use the bring-forward rule to contribute up to $360,000 in a single year.

Non-concessional contributions do not provide an upfront tax deduction, but the investment earnings on those contributions are taxed at a maximum of 15% in accumulation phase (and 0% in pension phase), which is significantly lower than most individuals' marginal tax rates. Over the long term, this concessional tax treatment on earnings can be very powerful.

Watch Your Total Super Balance

Your ability to make non-concessional contributions depends on your Total Superannuation Balance at the previous 30 June. If your balance was $1.9 million or more at 30 June 2025, your non-concessional cap for 2025-26 is nil. Between $1.66 million and $1.9 million, the bring-forward amount is reduced. These thresholds are critical to check before making any contribution.

Strategy 6: Check Your Employer's SG Payments

It is remarkably common for employer SG contributions to be late, underpaid, or in some cases, not paid at all. Under the current quarterly system, SG must be paid within 28 days of the end of each quarter. With the transition to payday super from 1 July 2026, the compliance environment is changing, but for the 2025-26 financial year, the quarterly rules still apply.

Before the end of the financial year, log in to your super fund and verify that all four quarters of SG have been received:

• Q1 (July-September): due 28 October 2025
• Q2 (October-December): due 28 January 2026
• Q3 (January-March): due 28 April 2026
• Q4 (April-June): due 28 July 2026 (this one falls in the next financial year)

If any payments are missing, raise the issue with your employer first. If the matter is not resolved, you can report unpaid super to the ATO, which has the power to pursue the employer for the outstanding contributions plus interest and penalties.

Strategy 7: Review Insurance Inside Super

Many Australians hold life insurance, total and permanent disability (TPD) insurance, and income protection insurance within their super fund. The premiums are deducted from your super balance, which can erode your retirement savings over time if not managed carefully.

Before 30 June, review the following:

• Is your cover appropriate? Life circumstances change. If you have paid off your mortgage, your children are independent, or your financial obligations have reduced, you may be over-insured.
• Do you have duplicate cover? If you have multiple super accounts, you may be paying for insurance in each of them. Consolidating to a single fund can eliminate unnecessary premiums.
• Are the premiums competitive? Default insurance inside super is not always the cheapest or most appropriate. Compare your cover with alternatives, both inside and outside super.
• Is the insurance structure correct? For example, TPD insurance can be offered on an "any occupation" or "own occupation" basis, with significant differences in claim outcomes. The structure matters as much as the sum insured.

Your EOFY Super Checklist

Use this checklist to ensure you have covered the key strategies before 30 June 2026:

• Calculate your year-to-date concessional contributions and identify remaining cap space
• Check if you are eligible for carry-forward contributions (TSB under $500,000 at 30 June 2025)
• Arrange additional salary sacrifice or make a personal deductible contribution
• Submit your Notice of Intent to Claim a Deduction if making personal deductible contributions
• Consider a spouse contribution if your partner's income is below $40,000
• Make a $1,000 non-concessional contribution to trigger the government co-contribution (if eligible)
• Review your non-concessional contribution capacity and consider a lump-sum contribution
• Verify all employer SG contributions have been paid and received by your fund
• Review insurance held within super for appropriateness, duplication, and cost
• Consolidate multiple super accounts to reduce fees and simplify management
• Check your nominated beneficiaries are up to date (binding nominations typically expire after three years)
• Book a review with your financial adviser to model the impact of any contributions

The Cost of Doing Nothing

Superannuation contribution strategies are not speculative. They rely on established rules and deliver predictable tax outcomes. Yet every year, billions of dollars in cap space goes unused simply because people do not act before the deadline. A $30,000 concessional contribution for someone in the 45% marginal tax bracket produces a net tax benefit of approximately $7,050. Failing to make that contribution costs you real money.

The difference between a well-optimised super strategy and an ad hoc approach is often tens of thousands of dollars over a decade. The rules are there for everyone. The advantage goes to those who use them.

If you are unsure about your contribution position, your eligibility for carry-forward amounts, or how to coordinate these strategies with your broader financial plan, seek professional advice. The cost of a single consultation is a fraction of the potential benefit.
