Carry-Forward Concessional Contributions: Using Your Unused Caps
Written by Kurt Armbruster, Financial Adviser | Last reviewed: 21st September 2026
The concessional contribution carry-forward rules allow eligible individuals to access unused concessional contribution caps from up to five previous financial years. This provides a significant opportunity for those who have experienced fluctuating income, taken career breaks, or recently received a large lump-sum payout.
By “topping up” their superannuation using these carried-forward amounts, individuals can reduce their taxable income in high-earning years and accelerate their retirement savings. To be eligible, your total superannuation balance must be below the legislated threshold at the end of the previous financial year. This is a powerful strategy for tax management, but it requires diligent record-keeping of your historical cap usage. Working with an adviser to calculate your eligibility is highly recommended to avoid inadvertent breaches of contribution caps.
Who benefits from carry-forward contributions?
This rule is particularly advantageous for professionals whose earnings vary significantly from year to year, such as consultants, real estate agents, or primary producers. In lower-income years where the standard annual concessional cap ($32,500 in 2026-27) is not fully utilised, the unused portion automatically rolls forward on a rolling five-year basis. When a high-earning year occurs, the individual can absorb these accumulated cap amounts in addition to the standard annual cap, creating a substantial tax deduction that offsets marginal income tax liabilities.
Am I eligible to use carry-forward contributions?
To successfully implement a carry-forward strategy, individuals must verify that their total superannuation balance was under $500,000 as of 30 June of the preceding financial year. The Australian Taxation Office (ATO) tracks unused cap amounts automatically, but cross-referencing these records against personal contributions and employer Superannuation Guarantee payments is vital. Concessional contributions apply on a first-in, first-out basis, ensuring that the oldest available carry-forward caps are applied first before expiring after the five-year window closes.
If you are making a personal contribution and claiming it as a tax deduction, you must also give your super fund a valid notice of intent to claim a deduction and receive the fund’s acknowledgement before you lodge your tax return.

Using carry-forward contributions to offset a capital gain
In practice, utilising carry-forward provisions can also buffer against major capital gains events, such as selling an investment property or liquidating a share portfolio outside of superannuation. Making a large personal deductible contribution up to the maximum carry-forward threshold can offset the capital gain, effectively converting a taxable liquidity event into a boosted retirement fund. Strategic planning ensures that these contributions are executed prior to the end of the financial year to capture full tax relief.
For business owners selling business assets, the small business CGT concessions may offer a further way to move sale proceeds into super.
Carry-forward contribution FAQs
Unused concessional cap amounts can be carried forward for up to five financial years. After five years, any unused amount expires. The oldest unused amounts are applied first when you make contributions above the annual cap, so it pays to use them before they fall out of the window.
Your total superannuation balance must be below $500,000 at 30 June of the previous financial year. The balance is measured across all of your super accounts. If you are above $500,000, you can still contribute up to the standard annual concessional cap, but you cannot use carried-forward amounts that year.
You can see your unused concessional cap amounts in ATO online services through myGov, under the super section. It is worth checking these figures against your fund statements and payslips, because late employer contributions or unreported salary sacrifice can make the ATO figure differ from what you expect.
There is no separate application. The ATO applies carried-forward amounts automatically when your concessional contributions exceed the annual cap and you are eligible. If you make a personal contribution and want to claim it as a deduction, you must lodge a notice of intent with your fund and receive its acknowledgement before lodging your tax return.
