Super Through a Career Change or Income Gap

01 Why a gap costs more than it looks

When you change careers and contributions pause — whether from lower income, self-employment, or time off — it's tempting to treat it as a minor, temporary thing. But super compounds, and a dollar not contributed in your 30s would have decades to grow. The calculator shows the effect: a one or two year gap can cost a surprisingly large amount by retirement, because the missed money loses the most years of growth. The gap itself is small; the forgone compounding is what stings, and it's invisible until decades later.

A pause in contributions is commonly treated as costing the contributions paused, and that understates it by a factor most people would find surprising. A dollar not contributed at 32 loses about thirty years of compounding as well as itself, so the same two-year gap costs several times more in your thirties than in your fifties — which is precisely the age at which career breaks usually happen.

On the defaults above, the worked example shows: A 2-year pause costs about $105,473 by retirement — small now, large later, because the missed money loses the most compounding.

02 Going self-employed: replace the SG yourself

The fix is personal deductible contributions, which reach exactly the same tax outcome as salary sacrifice by a different route: you contribute from your own money, then claim a deduction, so the contribution is effectively taxed at 15% inside super instead of at your marginal rate. It counts toward the same $30,000 concessional cap.

One administrative step is easy to miss and fatal if you do. To claim the deduction you must lodge a notice of intent with your fund and receive their acknowledgement before you lodge your tax return — and before you start a pension, roll the money elsewhere, or withdraw any of it. Without a valid acknowledged notice the contribution still counts, but as a non-concessional one: no deduction, and it consumes your after-tax cap instead.

The advantage the self-employed have over employees is timing. You can wait until May or June, see what the year actually earned, and size the contribution to the income — which an employee on a fixed salary sacrifice arrangement cannot do. The disadvantage is that nothing is automatic, so the contribution competes every year with reinvesting in the business, and the business usually wins unless the decision is removed by making it a standing transfer.

The most common career-change super gap comes from going self-employed, where no employer pays the 11.5% Super Guarantee for you. The fix is personal deductible contributions: you contribute from your own money and claim a tax deduction, getting the same 15% concessional treatment as an employee's salary sacrifice. It takes discipline without an employer doing it automatically, but it's the same tax break — just self-directed. Even contributing a rough equivalent of the SG you've lost keeps the trajectory intact.

The cap is the part worth holding on to. That $30,000 is a single annual allowance across every concessional route, so a personal deductible contribution does not sit on top of salary sacrifice — it draws on the same room. For someone moving from employment to self-employment mid-year, the employer contributions already made count against it, and the amount left to contribute personally is the cap minus what the old job already used.

What genuinely changes is the timing. An employer pays the Super Guarantee whether or not you think about it; a personal contribution happens only when you decide to make one, and a year of trading is easy to finish without having made it. Treating the contribution as a quarterly transfer on the same rhythm an employer would have used is what keeps the trajectory intact, because it removes the decision rather than relying on it being made twelve times.

03 Refilling the gap with carry-forward

If you couldn't contribute much during the change, carry-forward lets you catch up later. Unused concessional cap from the previous five years can be used in a single year, provided your total super balance is under $500,000 — so a strong year after a lean career-change period can carry a much larger deductible contribution than the annual cap alone. This is the system's built-in mechanism for uneven careers: the gap doesn't have to be permanent, because the cap you didn't use is banked for up to five years.

04 Consolidate and check SG on the way through

A career change is the ideal moment for super housekeeping, because you are already dealing with paperwork and the cost of not doing it compounds.

Multiple jobs often leave multiple super accounts, each charging administration fees and insurance premiums on a balance that may be small. Three accounts can mean three sets of fixed fees and three overlapping default insurance policies, only one of which you could meaningfully claim on. Consolidating stops that — but check what insurance you would be cancelling first, because closing an account ends its cover and it may not be replaceable on the same terms after a health change.

Check the Super Guarantee was actually paid by the employer you are leaving. The final quarter is the one most likely to go missing, and it is far easier to raise while the relationship is current than a year later. Log in to myGov, link the ATO, and compare the contributions your fund has reported against the SG line on your final payslips.

Also check for lost super at the same time. The ATO holds accounts that have been transferred to it from inactive low-balance funds, and reclaiming them takes minutes through myGov. Someone with a varied work history frequently finds a few thousand dollars they had forgotten about.

None of this is large individually. Together, done once at the point of a job change, it routinely recovers more than a year of voluntary contributions would have added.

A career change is the ideal moment for super housekeeping. Multiple jobs often leave multiple super accounts, each charging fees and insurance premiums — consolidating into one (while keeping any insurance you need) stops paying several times over. It's also the time to check your employer was actually paying your SG correctly before you left, via your myGov ATO record, since underpayment is common and recoverable. And when you start a new role, you can usually choose your fund rather than defaulting to the employer's, keeping your super in one low-fee place across job changes.

05 If a partner keeps earning

If you're part of a couple and one of you takes the income hit during a career change, the household has extra tools. The higher-earning partner can split up to 85% of their concessional contributions into the lower earner's super, and can make a spouse contribution for a tax offset if the lower earner's income is small. These don't fully replace lost contributions, but they keep the lower-earning partner's balance growing through the gap and stop a career change from skewing the couple's super heavily toward one person — which matters for using two transfer balance caps later.
