The government super co-contribution: a free 50% boost for low and middle-income earners

For most super strategies, the benefit is long-term and indirect — contributions grow and compound over decades before paying off. The government super co-contribution is different. For eligible members who make a personal after-tax contribution to super, the government adds 50 cents for every dollar contributed, up to a maximum of $500 per year. That is a guaranteed 50% return on the qualifying contribution, credited directly into super — and it requires no application form. It simply flows through the tax return automatically.

It is not available to everyone. The co-contribution is explicitly designed for low and middle-income earners, and the income test phases it out entirely once income exceeds the upper threshold. But for people who do qualify — part-time workers, non-working spouses, older workers reducing their hours, and anyone with a year of lower-than-usual income — it is one of the simplest high-return retirement strategies available.

How does the government co-contribution work?

The co-contribution applies to personal non-concessional contributions (after-tax contributions made from personal funds). It does not apply to salary sacrifice, employer contributions, or personal deductible contributions — those are concessional and processed differently. To get the maximum $500 co-contribution, a member needs to make a personal NCC of $1,000 or more in a financial year. The government matches at 50 cents per dollar up to $500, so any amount above $1,000 does not generate additional co-contribution. The personal contribution does count toward the standard $120,000 non-concessional contributions cap.

After the tax return is lodged for the year, the ATO calculates the co-contribution amount based on income and the contributions made, and pays it directly to the member's super fund. No action is required beyond lodging the tax return and confirming that the super fund's details are up to date with the ATO.

What are the eligibility conditions?

Several conditions must all be met in the same financial year.

Income must be below the upper threshold. Confirmed FY2025-26 income thresholds (FirstTech Historical Super Rates 2025-26 Table 5; ATO): lower threshold $47,488 (full $500 co-contribution available where the eligible NCC of $1,000+ is made); upper threshold $62,488 (no co-contribution above this). The maximum co-contribution is $500 per FY2025-26 (50 cents per dollar of eligible personal NCC, capped). The co-contribution phases down on a straight-line basis between the lower and upper thresholds: at the midpoint, approximately half the maximum is available. Income for this purpose includes employment income, business income, and reportable items (reportable fringe benefits, reportable employer super contributions), but not investment income alone — the test is designed to target working members.

At least 10% of total income must come from employment or business activities. A retiree living entirely on investment income or account-based pension drawdowns does not qualify, even if their income is below the threshold.

The member must be under age 71 at the end of the income year, and an Australian tax resident.

Total Super Balance (TSB) must be below the general Transfer Balance Cap — for FY2025-26, that cap is $2.0 million. Members with a TSB at or above $2.0 million are ineligible.

Who does the co-contribution matter most for?

Part-time workers are the most natural beneficiaries. A person working reduced hours — either by choice or necessity — and earning below the lower threshold can capture the full $500 co-contribution each year they make a qualifying $1,000 NCC. Over ten years, that is $5,000 of free government contributions plus investment growth on each year's amount.

Non-working spouses who have returned to part-time work often land in exactly the qualifying income range. Their own super may be underdeveloped compared to a working partner's, and the co-contribution is one of the targeted tools designed to address that. Combined with contribution splitting from the working partner and potentially the spouse contributions tax offset, a non-working or part-time spouse can benefit from multiple simultaneous strategies building their super.

Older workers transitioning to part-time — whether phasing into retirement or managing health — frequently have years where their income drops below the threshold. Those years are co-contribution eligible, and the window to accumulate in super is still meaningful even at 60–65 if the member has not yet started drawing pension.

How does the co-contribution stack with other strategies?

The co-contribution works alongside, not instead of, other contribution mechanisms. A couple with super imbalance might deploy: the working spouse splitting concessional contributions to the lower-balance spouse (up to $25,500 per year); the working spouse also making direct spouse contributions (attracting a tax offset if the receiving spouse earns below $40,000); and the lower-income spouse making their own $1,000 NCC each year to capture the co-contribution. These three mechanisms address the same underlying problem — imbalanced super — from different angles simultaneously, and each is available without affecting the others.

The co-contribution is separately modest — $500 per year. The reason it is worth pursuing is that it compounds. $500 at age 50 invested in super for 17 years at typical long-term super fund returns grows to materially more by retirement age, and it costs only the qualifying $1,000 NCC contribution to unlock it each year.
