Super and Parental Leave: Protecting the Balance
Time out of paid work to raise children usually pauses super contributions — and because it often happens early in a career, it's a major driver of the retirement gender gap. Recent changes add super to government Paid Parental Leave, and couples have tools to close the rest of the gap.
- The gap: unpaid or low-paid leave pauses super contributions early in a career, when compounding matters most — a leading cause of women retiring with less.
- The change: from 1 July 2025, the government pays superannuation on its Paid Parental Leave, helping reduce the gap at the source.
- The tools: a working partner can split contributions or make spouse contributions, and carry-forward lets the returning parent catch up later.
When Cass's sister-in-law took a year off with her first child, her super simply stopped growing for twelve months — a small pause that, compounded over thirty years, is anything but small. It's the quiet mechanism behind the retirement gender gap.
01 Why parental leave dents super
Super is paid as a percentage of wages, so when paid work pauses for parental leave, contributions usually pause too — many employers don't pay super on unpaid leave. Because this often happens in your 30s, the missed contributions lose decades of compounding, making the long-run cost far larger than the leave period suggests. The calculator shows the effect of a leave gap compounded to retirement. Repeated across more than one child, and often combined with returning to part-time work, this is a primary reason women in Australia retire with substantially less super than men.
Shows: the long-run retirement cost of a period of leave with no super contributions, compounded to retirement. Ignores: the new super on government Paid Parental Leave (from 1 July 2025), spouse contributions, and any employer-paid parental super.
Many parents assume that pausing their own contributions during leave simply pauses their own money, and reduce or opt out on that basis. During paid parental leave the employer must keep contributing on your normal full salary while your own contribution is based on the reduced pay — an unusually favourable ratio that opting out forfeits entirely. It is the one period where staying in is worth more than it appears.
On the defaults above, the worked example shows: Missing 12 months of super costs about $72,758 by retirement — part of the super gap that contributes to women retiring with less.
02 Super now paid on government Paid Parental Leave
A significant change helps at the source: from 1 July 2025, the government pays a superannuation contribution on its Paid Parental Leave, so parents receiving it now accrue some super during that period rather than none. It doesn't replace a full salary's worth of contributions, but it directly targets the gap by ensuring government-funded leave isn't entirely super-free. Check what your own employer offers too — some pay super on employer-funded parental leave, and a growing number continue super contributions during paid and even unpaid parental leave as a deliberate equity measure.
The change is commonly read as closing the parental-leave super gap, and it does not close it. Super on government Paid Parental Leave is a genuine improvement, but it is calculated on the statutory payment rather than on your normal salary — so someone earning $90,000 still accrues far less than they would have working, and the gap narrows rather than disappears.
03 A working partner can help directly
Contribution splitting lets the working partner transfer up to 85% of a financial year's concessional contributions into the other's super. It is applied for after the year ends, using a form from the contributing partner's fund, and it moves real money — often $15,000 or more — into the account that has stopped receiving anything. Over a two-year leave period that can close most of the gap.
The spouse contribution offset works from the other direction. If the partner on leave has income of $37,000 or less, the working partner can contribute up to $3,000 to their super and claim a tax offset of up to $540. It is a smaller amount but it is a direct rebate rather than a transfer, so the household is genuinely better off.
The two stack, and neither reduces the other. A household using both moves the working partner's concessional contributions across and adds $3,000 of after-tax money with a $540 rebate attached — which is close to replacing a year of Super Guarantee for a mid-income earner.
Both require someone to act. Splitting has an application window tied to the following financial year, and the offset is claimed in a tax return, so a couple who plan to "sort the super out later" typically find the window for the leave year has closed.
Couples have two effective tools to keep the leave-taking partner's super growing. Contribution splitting lets the working partner transfer up to 85% of their concessional contributions into the other's super each year — a direct way to keep the lower-earning partner's balance moving during leave. And a spouse contribution can earn the contributing partner a tax offset of up to $540 if the receiving partner's income is low. Neither fully replaces a salary's worth of contributions, but together they stop the couple's super skewing entirely toward the working partner.

04 Catching up on return to work
Unused concessional cap from the previous five financial years can be used in a single year, provided your total super balance was under $500,000 at the previous 30 June. A leave period generates precisely that unused cap — you contributed little or nothing while the cap continued accruing — so the years that created the gap also created the room to close it.
The constraint is cash flow rather than eligibility. The year you return to work is rarely the year you have spare money, and the $500,000 test can switch the mechanism off as the balance grows. Someone planning to catch up "in a few years" may find the room expired — the oldest unused year drops off after five — or the balance test has closed the door.
Two things make it more achievable. The contribution can be made as a personal deductible contribution rather than through salary sacrifice, so it can be a single payment before 30 June once the year's income is known, rather than a monthly commitment. And it is worth doing in the highest-income year available, because the deduction is worth your marginal rate.
Check the available figure in ATO online services through myGov before planning around it, because reconstructing it from payslips reliably understates what is there.
When the returning parent's income picks back up, carry-forward is the catch-up mechanism. Unused concessional cap from the previous five years can be used in one year if total super balance is under $500,000 — so the leave period's unused cap isn't lost, it's banked. A parent returning to work, especially to a higher income, can make larger deductible contributions to make up ground, capturing the 15% tax break while refilling the gap. The system is designed to accommodate uneven contribution patterns exactly like this.
05 The co-contribution on return to part-time
Many parents return to part-time work first, on a lower income — which opens up the government super co-contribution. If you earn under the threshold and make a personal after-tax contribution, the government adds up to $500 (50c per dollar), a guaranteed 50% return that's especially valuable at the lower incomes common after returning from leave. Combined with carry-forward for the higher-income years and a partner's splitting during the leave itself, a family can largely close a parental-leave super gap over time — but it takes deliberately using these tools, not assuming it sorts itself out.
Source: ATO — Super co-contribution
The parental-leave super gap is one of the clearest, most fixable inequities in the system, and it's finally being addressed at the source now that government Paid Parental Leave includes super. But the policy change alone won't close it — couples have to use the tools. The move I push hardest: the working partner splits contributions to the one on leave, so the household's super doesn't lurch onto one balance during the very years compounding matters most. Add the co-contribution on the part-time return and carry-forward later, and a year off doesn't have to mean a smaller retirement. Treat it as a shared household balance, not two separate ones.
FAQ
Does parental leave affect my super?
Usually yes — super is paid on wages, so when paid work pauses for leave, contributions often pause too, and many employers don't pay super on unpaid leave. Because it happens early in a career, the compounding cost is large.
Is super paid on Paid Parental Leave?
From 1 July 2025, the government pays a superannuation contribution on its Paid Parental Leave, so parents accrue some super during that period. Some employers also pay super on their own parental leave.
How can my partner help my super during leave?
A working partner can split up to 85% of their concessional contributions into your super each year, and make a spouse contribution for a tax offset of up to $540 if your income is low.
How do I catch up on super after parental leave?
Use carry-forward — unused concessional cap from the previous five years can be used in one year (if your total super balance is under $500,000) — and the co-contribution if you return on a lower part-time income.
