What Happens to a Super Account You Stop Using
The Protecting Your Super rules exist because small super accounts were being consumed by fees and premiums faster than they grew. They cap the fees chargeable on a low balance, cancel insurance on an account that has been inactive, and transfer small inactive balances to the ATO. Each of those is protective by default and each can be the wrong outcome for a particular person.
- The answer: Administration and investment fees on balances below the threshold are capped, exit fees are banned, and insurance is cancelled on accounts inactive for the specified period.
- The trap: Insurance cancellation is automatic. Someone on parental leave or between jobs can lose cover simply because no contribution arrived.
- The recommendation: If you want to keep cover on an account you are not contributing to, tell the fund in writing. An election overrides the automatic cancellation.
Where the AI summary above gets this wrong
"Protecting Your Super means your super fund cannot charge you excessive fees."
That's surface-true. Here's what it misses:
- The insurance rule is the one that actually affects people — Cover is cancelled automatically on an account that has received no contribution for the specified period, which catches people on parental leave, on extended leave, or between jobs.
- Small inactive balances leave the fund entirely — They are transferred to the ATO, where they earn interest but are not invested, so a balance sitting there falls behind a fund's long-run return.
01 The fee caps and the exit fee ban
For accounts below the low-balance threshold, combined administration and investment fees are capped at a percentage of the balance each year. That stops the situation where a small account was being eroded faster than contributions or returns could rebuild it.
Exit fees are banned outright on all accounts regardless of balance, which removes the cost of consolidating. Before the ban, rolling several accounts together could cost more than a year of the fees it saved.
Neither rule makes a small account a good place to leave money. The flat components of fees still bite proportionally harder on a small balance, which is why merging accounts remains the answer even with the caps in place. What the drag costs over a career is in the super fees post.

02 Automatic insurance cancellation
Insurance is cancelled on an account that has received no contribution or rollover for a continuous period, unless you have told the fund in writing that you want the cover maintained. The fund must write to you before cancelling, at the address they hold.
The people this catches are not people who abandoned an account. They are people on parental leave, on long-term sick leave, between jobs, working overseas, or self-employed in a year they did not contribute — which is to say, several of the groups most likely to need the cover.
The election to keep cover is a short written notice and it persists. Making it is the single most valuable action available in this area, and it costs nothing except that the premiums continue to be deducted, which is the point.

03 Transfers to the ATO
An inactive low-balance account is transferred to the ATO, which then attempts to consolidate it into an active account you hold. Where it cannot, the money stays with the ATO and earns interest at a rate set by legislation.
That interest is not a market return. A balance sitting with the ATO for a decade falls a long way behind the same money invested in a growth option, so recovering it is worth doing rather than leaving it as found money.
Recovery is done through myGov, which shows ATO-held amounts alongside your fund accounts. It is the same screen that finds lost super, and it is worth checking after any period of irregular work rather than only when you remember.
Shows: the gap between a balance left as ATO-held super earning the legislated interest rate and the same balance invested in a fund at a long-run return. Ignores: fees inside the fund, tax on earnings, and any insurance the fund account would have carried.
The insurance cancellation is the part that does real harm, and it does it to exactly the wrong people. Someone taking two years out to raise a child has an account receiving nothing and a family that depends on the cover. The election to keep it is a form and a signature. Make it before the leave starts, not after the letter arrives.
FAQ
What are the Protecting Your Super rules?
They cap administration and investment fees on low balances, ban exit fees, cancel insurance on accounts that have been inactive for the specified period, and transfer small inactive balances to the ATO.
Can I stop my insurance being cancelled?
Yes. Tell the fund in writing that you want the cover maintained. The election overrides the automatic cancellation and persists, and the premiums continue to be deducted.
What happens to super transferred to the ATO?
It earns interest at a rate set in legislation but is not invested, so it falls behind a fund's long-run return. You can claim it back into an active fund through myGov at any time.
