With the 2026-27 financial year now well underway, tracking your superannuation contribution caps is essential to maximise your retirement savings without triggering excess contributions tax. Missing the caps can cost you up to 47% in tax penalties, while underusing them means leaving tax-effective retirement savings on the table.

Understanding where you stand now, in late September 2026, gives you nine months to optimise your strategy before 30 June 2027.

What You Will Learn

This guide walks you through the current contribution caps, how to check your year-to-date contributions, calculate your remaining capacity, and plan your contribution strategy for the rest of the 2026-27 financial year. You will learn practical steps to avoid penalties and make the most of your available caps.

Step 1: Understand the Current Caps

According to the Australian Taxation Office, the concessional contributions cap for 2026-27 is $30,000 per year. Concessional contributions include employer Superannuation Guarantee (SG) payments, salary sacrifice contributions, and personal deductible contributions. These are taxed at 15% inside your super fund, making them highly tax-effective for most workers.

The non-concessional contributions cap is $110,000 per year. These are after-tax contributions made from your take-home pay. If you are under 75 and your total superannuation balance is below $1.9 million (as of 1 July 2026), you may access the bring-forward rule, allowing you to contribute up to $330,000 over three years.

As covered in foundational retirement planning texts such as Principles of Finance (OpenStax, 2022), contribution caps exist to limit the tax advantages available through superannuation while encouraging long-term savings.

Step 2: Check Your Year-to-Date Contributions

Log in to myGov and access your ATO online account. Navigate to the Super section and review your contributions for the 2026-27 financial year (1 July 2026 to 30 June 2027). The ATO updates contribution data regularly, though there may be a delay of one to two months depending on when your employer or fund reports.

You can also request a contribution statement from your super fund directly. Most industry and retail funds provide real-time dashboards showing your concessional and non-concessional contributions to date.

If you have multiple super accounts, add up contributions across all accounts. The caps apply to your total contributions, not per fund.

Step 3: Calculate Your Remaining Capacity

Subtract your year-to-date contributions from the relevant cap. For example, if you have made $12,000 in concessional contributions so far (including employer SG payments from July to September 2026), your remaining concessional cap is $18,000.

For non-concessional contributions, if you have made $20,000 in after-tax contributions so far, you have $90,000 remaining capacity for the year.

If you are eligible for catch-up concessional contributions (available if your total super balance was below $500,000 on 30 June 2021 or later), you may have unused cap amounts from previous years. Check your ATO online account for your available catch-up amount.

Step 4: Plan Your Contribution Strategy

Once you know your remaining capacity, decide how to use it. Common strategies include:

Salary sacrifice: Arrange with your employer to divert part of your pre-tax salary into super. This reduces your taxable income and uses your concessional cap. For workers on marginal tax rates above 30%, this delivers immediate tax savings.

Personal deductible contributions: Make after-tax contributions to your super fund and claim a tax deduction in your 2026-27 tax return. You must lodge a notice of intent to claim with your fund before lodging your return or before you withdraw or roll over the money.

Spouse contributions: If your spouse earns below $40,000, you can make non-concessional contributions on their behalf and potentially claim a tax offset of up to $540.

Top-up before 30 June 2027: If you receive a bonus, inheritance, or property sale proceeds later in the financial year, consider using part of it to top up your non-concessional contributions before the deadline.

Step 5: Time Your Contributions

Contributions must be received by your super fund by 30 June 2027 to count toward the 2026-27 caps. Employer contributions and salary sacrifice payments typically follow your pay cycle, so confirm the timing with your payroll team if you are adjusting your salary sacrifice late in the financial year.

For personal contributions (both deductible and non-concessional), allow at least five business days before 30 June for the payment to be received and processed by your fund.

Common Mistakes to Avoid

Exceeding the concessional cap triggers excess contributions tax, charged at your marginal tax rate plus an interest charge. Non-concessional cap breaches are taxed at the top marginal rate. Always leave a buffer to account for employer contributions you may not have visibility over, such as SG on bonuses or allowances.

Do not assume your super balance updates instantly. Contribution data can lag by several weeks, so check early and often.

If you are over 75, different rules apply. Non-concessional contributions are not permitted after age 75, and concessional contributions require you to meet the work test or work test exemption.

Frequently Asked Questions

Do employer SG contributions count toward my concessional cap?
Yes. Employer SG payments, salary sacrifice, and personal deductible contributions all count toward the $30,000 concessional cap.

Can I carry forward unused concessional cap space?
Yes, if your total super balance was below $500,000 on 30 June of the previous financial year. Unused amounts from the past five years can be carried forward. Check your ATO online account for your available catch-up concessional contributions.

What happens if I accidentally exceed the cap?
The ATO will send you an excess contributions determination. You can choose to withdraw the excess amount (plus 85% of associated earnings) or leave it in super and pay the excess contributions tax.

Conclusion

Planning your super contributions before 30 June 2027 ensures you maximise tax-effective retirement savings without penalties. Check your year-to-date position now, calculate your remaining capacity, and adjust your salary sacrifice or personal contributions accordingly.
