The Government Super Co-Contribution: Up to $500 Free

A guaranteed 50% return does not exist anywhere in investing. It does exist in the tax system, once, and it is the government super co-contribution.

The headline is simple: put in $1,000 of your own after-tax money and the government puts in $500. What is rarely explained is what happens between the two income thresholds — because above the lower one, there is a point where every extra dollar you contribute earns you nothing at all.

The basics

Make a personal after-tax (non-concessional) contribution to super, earn under the threshold and the government contributes 50 cents for every dollar, to a maximum of $500.

For 2026-27 the thresholds are:

The thresholds are indexed every 1 July, so the year matters — the Co-Contribution Calculator carries the figures for the year you pick rather than one set of numbers going stale.

The part that gets misunderstood

Read the middle row carefully. The taper reduces the maximum, not the match.

Your entitlement is the lesser of two things: 50 cents per dollar you contributed, and the maximum for your income. It is not the match with the taper then applied on top of it. That distinction sounds academic and is worth real money to anyone in the phase-out range.

It also means the interesting question is not "how much do I get for $1,000" but "how much do I need to contribute to reach my own maximum".

Where the extra dollars stop working

Take an income of $56,000 in 2026-27.

• You are $6,707 above the lower threshold
• Your maximum is reduced by 3.333c per dollar of that, leaving $276.43 — which the ATO rounds up to $276.45
• To collect that at 50c per dollar you need to contribute $553

Contribute $553 and you receive $276.45. Contribute $1,000 and you receive exactly the same $276.45. The last $447 attracted nothing.

That money is not wasted — it is in your super, and it counts toward your non-concessional cap. But it earned no government match, and anyone contributing "the full $1,000" because that is the figure in every headline is quietly getting a much lower return than they think.

The general rule: your optimal contribution is twice your tapered maximum. Below the lower threshold that is the familiar $1,000. Above it, it falls away fast.

Who is eligible

Beyond the income test, you generally need to:

• Make the contribution from after-tax money and not claim a deduction for it
• Earn at least 10% of your total income from employment or carrying on a business
• Be under 71 at the end of the income year
• Lodge a tax return for the year
• Be under the non-concessional contributions cap, with a total super balance under the general transfer balance cap

"Total income" here is not just your salary. It is broadly your assessable income plus reportable fringe benefits and reportable employer super contributions, less allowable business deductions. Salary sacrifice therefore does not help you qualify — it is added back.

The deduction trap

This is the most common way people lose the entitlement, and it is entirely avoidable.

The co-contribution rewards non-concessional contributions. Claim a tax deduction for your personal contribution and it becomes concessional, and it no longer counts. You cannot have both on the same dollar.

For someone in the co-contribution income range the choice is usually not close. A deduction on $1,000 at a 15% marginal rate is worth $150 and the contribution is then taxed 15% inside the fund, costing $150 — a net benefit near zero. The co-contribution on the same $1,000 is up to $500, paid in cash into your super. There is a fuller comparison in salary sacrifice vs after-tax super.

LISTO is a different scheme, and people mix them up

The Low Income Super Tax Offset is not the co-contribution. It refunds the 15% contributions tax on your concessional contributions, up to $500, if your adjusted taxable income is $37,000 or less. It requires no contribution of your own and no action at all — the ATO pays it to your fund automatically provided your fund holds your TFN.

You can receive both in the same year. One rewards money you chose to put in after tax, the other refunds tax on money that went in before tax.

Worth diarising: from 1 July 2027 the LISTO threshold rises from $37,000 to $45,000 and the maximum from $500 to $810. The co-contribution thresholds are unaffected by that change.

How and when you get paid

You do not apply. The ATO works the entitlement out once it has both your tax return and your fund's contribution reporting, then pays it into your super. That means it arrives some months after you contribute, and both halves have to be in — a fund that has not reported, or a return not yet lodged, simply delays it.

Two small mechanics worth knowing. If your calculated entitlement comes to less than $20, the ATO pays a $20 minimum anyway. That floor lifts a small entitlement, but it does not turn someone ineligible into a $20 payment. And payments are rounded up to the nearest 5 cents, which is why a calculated entitlement of $276.43 lands in your fund as $276.45.

Is it worth doing?

For anyone eligible, yes, with one honest caveat.

Even a fully tapered $276 on a $553 contribution is a 50% return before the money is invested. Nothing else available to a retail investor comes close, and it is not a forecast — it is legislated.

The caveat is liquidity. This is super, so the money is preserved until you meet a condition of release. If you might need it within a few years, a 50% return you cannot access is not the same as one you can. That is a genuine trade-off rather than a reason not to do it, and it is the only real argument against.
