Personal super contributions

It isn't the contribution that earns you the tax deduction. It's the notice.

Topping up your super and claiming it on tax is one of the simplest ways to reduce what you owe the ATO, but the deduction lives or dies on a single piece of paperwork, and the order you do things in.

If you've added money to your super from your own bank account, separate from what your employer pays in, you may be able to claim it as a tax deduction. It's called a personal deductible contribution, and thousands of people use it every year to lower their taxable income while boosting their retirement savings.

The mechanics of making the contribution are easy. What trips people up, often without realising until it's too late, is everything that happens after the money lands in the fund. Here's what actually determines whether your deduction survives.

Who can claim it

Anyone who makes a personal super contribution can claim a deduction, but the rules tighten with age.

Under 18

You can only claim a deduction if you earned income as an employee or from running a business during the year.

67–74

You need to meet the work test: gainfully employed for at least 40 hours within any 30-day period in the financial year. A once-only exemption exists if you met the test last year and your super balance was under $300,000.

75 and over

Your window closes 28 days after the end of the month you turn 75. Contribute after that and the money can still go into your super, it just won't be deductible.

The four steps that make it real

A personal contribution doesn't become a tax deduction automatically. It's treated as an ordinary contribution right up until your fund confirms, in writing, that they've received a valid Notice of Intent, often shortened to an NOI. Do the steps out of order, or take certain actions before step three is done, and the deduction can disappear entirely.

Make the contribution

Transfer the money into your super fund as a personal contribution, separate from your employer's payments and from any salary sacrifice arrangement.

Lodge your Notice of Intent

Tell your fund, in the approved form, how much of that contribution you intend to claim. This is due before you lodge your tax return for that year, or by the following 30 June, whichever comes first.

Wait for written acknowledgement

Your fund has to confirm receipt in writing. Nothing is claimable until this happens.

Rolling money out, withdrawing, or starting a pension before this point can shrink or wipe out what you're able to claim.

Claim it on your tax return

Once acknowledged, the amount counts as a deduction, and against your concessional contributions cap for that year.

The golden rule

Lodge your Notice of Intent and get written acknowledgement from your fund before you roll over, withdraw, split, or start a pension with any part of that money. Once one of those events happens, the notice can no longer cover the contribution, even if the amount involved is as small as a dollar.

Where deductions quietly disappear

A partial withdrawal or rollover

Take money out or roll part of your super to another fund before your notice is acknowledged, and only a proportion of your original contribution may still be eligible. The rest is treated as if it had already left the fund.
Starting a pension

Begin drawing an income stream from the same fund, and the entire contribution can lose its eligibility, regardless of how small a share of your balance the pension uses.
Wrong contribution type on record

If your fund logs the payment as an employer contribution instead of a personal one, you can't deduct it, and if it's already been reported to the ATO, it may not be fixable.
Timing against a property sale or payout

A capital gain is counted in the year the sale contract is signed, not the year settlement happens. A contribution meant to offset that gain needs to land, and be claimed, in the same financial year the contract was signed.

Keep an eye on the caps

Deductible contributions count toward your concessional contributions cap alongside anything your employer puts in, so it's worth checking your total before you lodge the notice, not after.

$32,500

General concessional cap for 2026/27. If your total super balance was under $500,000 last 30 June, unused cap from the past five years can top this up.

$250,000

Combined income and concessional contributions threshold above which an extra 15% Division 293 tax applies. Worth watching in a year with a one-off payout or property sale.

Treatment of excess

Go over your concessional cap and the excess doesn't disappear, it just gets taxed differently, and you get a choice about where it ends up.

Taxed at your marginal rate

Any excess concessional contributions are taxed at your individual marginal tax rate, less a 15% offset to account for the contributions tax your fund already paid.
You can choose to withdraw it

You have the option to withdraw the excess amount from your super, net of a 15% fund tax.
Otherwise it counts toward your NCC cap

Any excess you don't withdraw counts toward your non-concessional contributions cap instead.

The strategy is simple. The sequencing is where it pays to get advice.

If you're planning a personal contribution, especially alongside a property sale, a rollover, or starting a pension, talk to your financial adviser first. Getting the order right is the difference between a deduction and a missed one.
