Claiming a tax deduction on your personal super contributions: the Notice of Intent

For Australians who make personal contributions to superannuation — directly from their own bank account rather than through employer salary sacrifice — claiming a tax deduction on those contributions is not automatic. It requires a specific procedural step: lodging a Notice of Intent to Claim a Deduction with the super fund. Miss the step, miss the deduction.

Why does claiming a personal super contribution deduction matter?

When a personal contribution is made to super without claiming a deduction, it is treated as a non-concessional contribution — paid from after-tax money, not taxed further in the fund, but no deduction either. When a deduction is claimed, the contribution becomes a concessional contribution — the fund pays 15% contributions tax on it, but the member receives a personal income tax deduction at their marginal rate. For most Australians, the marginal rate exceeds 15%, so the net effect is a tax saving. At the 32.5% bracket, the saving is approximately 17.5 cents in the dollar of contributions. At 37%, it is 22 cents. At the top marginal rate including Medicare levy, it is approximately 32 cents.

For self-employed Australians — sole traders, partners in partnerships, business owners who draw income other than as salary — personal deductible contributions are the primary mechanism for tax-effective superannuation accumulation. Employer salary sacrifice is not available when there is no employing entity. The personal deductible contribution achieves the same economic outcome.

How does the Notice of Intent process work?

The steps are straightforward but must be followed correctly.

First, make the personal contribution from after-tax money to the super fund. Second, lodge a Notice of Intent to Claim a Deduction with the fund — using the ATO-approved form or the fund's own approved equivalent. Third, receive a written acknowledgment from the fund that the notice has been processed. Fourth, claim the deduction in the personal income tax return for the year the contribution was made.

The Notice of Intent is what converts the contribution from non-concessional to concessional. Without it, the contribution is locked as non-concessional regardless of intent.

When must the Notice of Intent be lodged?

The notice must be lodged with the fund by the earlier of two dates: the day the member lodges their income tax return for the financial year in which the contribution was made, and the end of the financial year following the year of contribution. The practical consequence is that lodging the tax return before lodging the Notice of Intent forfeits the deduction — the return lodgment triggers the earlier deadline and the notice opportunity is gone.

For most members, the safest approach is to lodge the Notice of Intent as soon as the contribution has been processed — well before tax return preparation begins. If there is any possibility the fund will be wound up, a pension will be commenced, or a partial withdrawal will be made from the account, the Notice should be lodged even earlier: certain events (commencing an income stream, making a lump sum withdrawal, rolling over the balance) can invalidate a notice or require it to be submitted before those events occur.

What eligibility rules apply to members aged 67 to 74?

Members under 67 can make personal deductible contributions without any work test requirement. For members aged 67 up to and including the 28th day after the end of the month they turn 75, the position is more nuanced.

Super funds can accept contributions from members in this age group without confirming that the member has satisfied a work test — the 2022 legislative changes removed that requirement from the fund's acceptance obligations. However, to actually claim a tax deduction for the contribution, the member in this age bracket still needs to satisfy the work test or the work test exemption.

The work test requires gainful employment for at least 40 hours in any period of 30 consecutive days during the income year in which the contribution was made. The work test exemption provides an alternative for members who met the work test in the prior income year and whose total super balance at the end of that prior year was below $300,000 — but it is available once only.

For members who have ceased employment and intend to make personal deductible contributions in retirement, the work test eligibility question must be specifically assessed for each year.

How does the concessional contributions cap apply?

Personal deductible contributions count against the concessional contributions cap, which is $30,000 per year in 2025-26. The cap is shared with employer SG contributions, salary sacrifice contributions, and any other concessional contributions from all sources. A member whose employer contributes $9,000 in SG during the year has $21,000 of concessional cap remaining for personal deductible contributions.

Members with total super balances below $500,000 at the prior 30 June can access unused cap from previous years through carry-forward provisions, potentially allowing significantly higher concessional contributions in a single year.

Excess concessional contributions above the cap are included in assessable income and taxed at marginal rates, with a 15% offset to account for tax already paid in the fund.

What are the most common errors with personal super contribution deductions?

The most common error is failing to lodge the Notice of Intent at all — the contribution is made with the intention to claim a deduction, but the Notice is never lodged, or it is lodged after the tax return has already been submitted. The deduction is then lost entirely. The second most common error is lodging the Notice for an incorrect amount. If the amount on the notice differs from the contribution actually made, only the amount on the notice is treated as concessional. Members who have contributed to multiple super funds need a separate Notice for each fund holding contributions they wish to claim as deductible.
