2026–26 Australians: Get Fund Acknowledgement to Claim Personal Super

Member checking super fund acknowledgement

You can claim a tax deduction for personal super contributions you make from after-tax income, as long as you meet eligibility rules and your fund gives written acknowledgement of a valid notice. Once claimed, the contribution converts from non-concessional to concessional and is generally taxed inside the fund at 15% instead of your marginal rate. That conversion also eats into your concessional cap, so the deduction is a trade-off, not free money.

TL;DR:

  • Claiming a personal super contribution converts it into a concessional contribution taxed at 15%, which reduces the concessional cap and may limit further deductible claims.
  • Eligibility depends on making an after-tax contribution to a complying fund before June 30 and providing a valid notice that the fund acknowledges in writing.
  • Contributions from defined benefit funds, untaxed funds, downsizer contributions, and recontributions under the First Home Super Saver Scheme are ineligible for claiming deductions.
  • The concessional cap for 2025-26 is $30,000, rising to $32,500 from July 1, 2026, with unused cap amounts potentially carry-forwarded for five years.
  • Claiming involves multiple steps, including transferring funds, submitting a notice before deadlines, and waiting for fund acknowledgment, with amendments possible if acknowledgment is delayed.

Quick checklist: is claiming worth it this year?

Claiming a personal deductible contribution tends to suit people whose income does not flow through a standard employer super guarantee, or anyone wanting a year-end top-up against a higher-than-usual tax bill.

  • Check whether you are self-employed, have irregular income, or received a bonus that pushed you into a higher bracket this year.
  • Add up employer contributions, salary sacrifice, and any amount you plan to claim to confirm you stay under your concessional cap before you contribute.
  • Confirm your fund accepts personal deductible contributions and understand that the money becomes preserved once it is in, generally until retirement.

Who is eligible to claim, and which funds are excluded

To claim, you need to have made a personal contribution from after-tax money to a complying super fund or retirement savings account, and the fund must still hold that contribution when you lodge your notice. The Australian Taxation Office confirms that eligibility depends on meeting these conditions alongside giving a valid Notice of intent and receiving the fund’s written acknowledgement.

Age and work rules matter too. If you are between 67 and 74, you generally need to meet a work test or qualify for a limited exemption, while people under 18 can only claim a deduction if they also earned income from employment or business during the year. The notice itself must reach your fund by the earlier of your lodgment date or 30 June of the following financial year.

Some contributions simply cannot be claimed. Defined benefit funds and certain untaxed funds often exclude deductible contributions, and downsizer contributions or amounts you have recontributed under the First Home Super Saver Scheme are never eligible.

How caps and the 15% contributions tax interact with Division 293

Once you lodge a valid notice and your fund acknowledges it, the contribution stops being non-concessional and starts counting toward your concessional cap, alongside employer super guarantee payments and any salary sacrifice you already arranged. Mixing these up is one of the most common planning mistakes, since people often forget to check what their employer has already reported before deciding how much to claim.

Flow from personal contribution to concessional cap

The concessional contributions cap sits at $30,000 for the 2025-26 financial year and rises to $32,500 from 1 July 2026, according to the ATO’s cap guidance. If your total super balance is under the relevant threshold, you may also carry forward unused cap amounts from the previous five years, which can let you claim a larger deduction in a single year.

Inside the fund, a claimed contribution is generally taxed at 15%. Go over your concessional cap and the excess is taxed at your marginal rate with an interest charge added, which is why checking your running total before contributing matters more than checking it afterward.

How to make the contribution and lodge your Notice of intent

The process has a clear order, and skipping a step is what causes most delays.

  1. Transfer the money to your super fund from your own bank account and keep the payment confirmation or bank statement as evidence.
  2. Complete the ATO’s Notice of intent form (NAT 71121) or your fund’s equivalent, including the exact contribution amount, the financial year, and your member details.
  3. Submit the notice to your fund before the earlier of your lodgment date or 30 June of the following year.
  4. Wait for your fund’s written acknowledgement before you claim anything on your tax return, since this acknowledgement is the actual control point, not the payment itself.

Pro Tip: Submit your Notice of intent weeks before you plan to lodge, since some funds take time to process and acknowledge, and the ATO will not allow the deduction without that written confirmation.

Working out how much you can safely claim

Before you nominate a deduction amount, add up every concessional contribution already made on your behalf this year: employer super guarantee, any salary sacrifice arrangement, and contributions reported by other funds if you hold more than one account or have gone through a successor fund transfer. Subtract that total, plus any amount you intend to claim, from your cap (including carry-forward space if you qualify) to see how much room remains.

  • Keep every payment receipt showing the contribution left your bank account and reached the fund.
  • Retain a copy of your signed Notice of intent and the fund’s written acknowledgement together.
  • Save your own cap calculation showing employer, salary sacrifice, and claimed amounts side by side.

A salaried employee earning $90,000 with $10,800 in employer contributions might claim a $15,000 personal deduction and stay well under the $30,000 cap. A sole trader with no employer contributions has more room to claim a larger amount in a single year, provided their fund acknowledges the notice before they lodge.

Reporting the deduction in myTax and fixing a late acknowledgement

Personal super deductions are entered under the deductions section in myTax, and the ATO requires your fund’s acknowledgement before the amount can actually be claimed. If your fund has not acknowledged the notice by the time you need to lodge, you can lodge your return without the deduction and amend it later once acknowledgement arrives, rather than waiting and risking a late lodgment.

Amending is straightforward through myTax or your registered tax agent once you have the acknowledgement in hand, and the ATO generally processes these amendments within normal review timeframes.

Weighing liquidity, preservation, and other concessions

Money you contribute and claim as a deduction is locked away until you meet a condition of release, typically reaching preservation age or retiring, so check your short-term cash needs before committing funds you might want sooner. Claiming a deduction can also reduce your eligibility for the government co-contribution and the Low Income Super Tax Offset, and it may push you closer to the Division 293 threshold if your income is already high. Where spouse splitting, the spouse contribution tax offset, or early access to capital are part of your plan, modelling the full picture before you contribute beats guessing.

Model before you commit

The tax saving from claiming a deduction looks attractive on paper, but the real question is whether locking money away until preservation age beats keeping it liquid or directing it elsewhere, like paying down a mortgage. Running the numbers side by side, including concessional tax, Division 293 exposure, and long-term balance growth, gives a clearer answer than a single-year tax calculation ever will. Where your situation involves multiple income streams, business ownership, or complex caps, a licensed financial adviser can confirm the figures specific to you.

FAQ

Is it worth claiming personal super contributions?

It depends on your income, tax bracket, and how much you value the tax saving against locking the money away until preservation age. For many people on higher marginal rates, paying only 15% contributions tax instead of their marginal rate makes claiming worthwhile, but you should check your cap position and Division 293 exposure first using ATO guidance.

What expenses are tax-deductible in Australia?

Deductible expenses generally include work-related costs, self-education tied to your current role, and personal super contributions when you meet the eligibility and notice requirements described above. Each category has its own rules, so personal super contributions require a valid Notice of intent and fund acknowledgement before they can be claimed.

Where do I find the Notice of intent to claim a tax deduction form?

The approved form, NAT 71121, is available through the ATO’s official instructions page, and many super funds also provide their own equivalent version. Either version works, but your fund must acknowledge it in writing before you claim the deduction.

Do I need to pay superannuation as a sole trader?

Sole traders are not required to pay themselves super guarantee contributions, which is why personal deductible contributions are a common planning tool for the self-employed, as MoneySmart explains. Making contributions voluntarily and deciding at tax time whether to claim them gives sole traders flexibility that employees with employer contributions do not have in the same way.

Authoritative ATO and MoneySmart resources

For the official forms and current figures, consult the ATO’s personal super contributions page, the Notice of intent instructions, concessional cap guidance, and myTax reporting instructions.
