More than 93,000 self-managed super funds are behind on their annual returns. If yours is one of them — or one of your clients' funds is — the window to fix it quietly is closing. The ATO has put overdue lodgement squarely on its 2026 compliance agenda, and the consequences of staying behind escalate faster, and more publicly, than most trustees realise.
Here's the scale of the problem, what actually happens when a fund falls behind, and why the 45-day audit rule means catching up is something you have to start now — not at the deadline.
The backlog the ATO is done ignoring
As at 31 December 2025, more than 93,000 SMSFs had one or more outstanding annual returns. Of those, around 20,000 have never lodged a single return — many registered purely to roll money out of an APRA-regulated fund and then left dark.
The ATO calls that cohort the "never lodgers", and describes it as the highest-risk group from its compliance perspective. Almost 40% of funds that registered, took a rollover and never lodged end up illegally accessing their super — and the value of that illegal early access rose by nearly 40% last year. If your fund sits in that group without a compliance problem, you are still standing in the same queue as the funds that do.
Addressing overdue annual returns is, in the ATO's own words, one of its current compliance priorities. Deputy Commissioner Ben Kelly put the reasoning plainly at the SMSF Association National Conference in February 2026:
"Lodgment is the cornerstone of compliance. It is how trustees can best demonstrate they are meeting their legal responsibilities."
An annual return isn't just a tax form — it's the mechanism by which you evidence that the fund is being run within the law. Miss it, and the regulator's working assumption shifts from "compliant until shown otherwise" to "why can't we see this fund?"
What actually happens when you fall behind
This is where trustees are caught off guard. The consequences aren't only financial, and they don't wait long.
Two weeks overdue — the fund goes dark on Super Fund Lookup
Once an SMSF's annual return is two weeks overdue, the ATO removes the fund's regulation details on the first business day of the month. Super Fund Lookup then shows the status "Regulation details removed."
While the fund sits in that state:
- Rollovers stop. APRA-regulated funds are not able to roll money over to a fund with regulation details removed — so consolidations and transfers in simply fail.
- Employer contributions dry up. The ATO advises employers not to contribute to a fund whose compliance status is unclear, and payroll teams and clearing houses check Super Fund Lookup before paying. In practice, super guarantee and salary sacrifice stop landing in the fund. A related-party employer can still contribute, but takes on real risk if the fund is later found non-complying.
It is also visible. Anyone — an employer, an adviser, a counterparty — can search the fund and see the status.
The status doesn't clear the moment you lodge, either. Once the overdue returns are in, the ATO updates regulation details twice a week, on Mondays and Wednesdays, with the change appearing on Super Fund Lookup the following business day. That happens automatically, so there is no need to call the ATO to chase it — but it does mean a lag between lodging and money being able to flow again.
Failure-to-lodge penalties
The ATO can apply a failure-to-lodge (FTL) penalty of one penalty unit for every 28 days (or part thereof) a return is overdue, capped at five units per return.
From 1 July 2026 a Commonwealth penalty unit rose to $364 (up from $330), so a return that falls overdue on or after that date attracts up to $1,820. Older years accrue at the unit value in force when they fell due — $330 or less — so a four- or five-year backlog runs to something under $10,000 in FTL penalties alone, before a cent of tax, interest or catch-up audit fees.
Two things worth being precise about. The FTL penalty is levied on the fund, and it is not deductible to the fund. Separately, the failures that tend to travel with a backlog carry administrative penalties under section 166 of the SIS Act — not preparing the fund's accounts and statements, or not giving the auditor requested documents within 14 days. Those penalties are personal: they apply to each individual trustee (or once to a corporate trustee, with the directors jointly and severally liable) and cannot be paid or reimbursed out of fund assets.
The worst case — non-complying status
If the ATO issues a Notice of Non-Compliance, the arithmetic changes completely. In the year the fund becomes non-complying, its assessable income includes the market value of the fund's total assets less its non-concessional (undeducted) contributions — and that amount is taxed at 45%, not the concessional 15%. It is effectively a one-off tax on the whole asset pool, and the fund continues to be taxed at 45% for as long as it stays non-complying.
That sits on top of the other sanctions the ATO can reach for: administrative penalties, rectification and education directions, enforceable undertakings, and disqualification of the trustees.
Why the 45-day clock changes your timeline
Here's the part that catches people out. You cannot simply "lodge and be done." Every outstanding year has to be independently audited first, and under section 35C of the SIS Act and regulation 8.02A of the SIS Regulations trustees must appoint an approved SMSF auditor at least 45 days before the annual return is due to be lodged.
Two things follow from that, and both argue for acting today:
- For years already overdue, the 45-day deadline has passed. You can't un-miss it — but every further week without an appointment compounds the breach and delays the audits that unlock lodgement.
- For the current year, 45 days is a statutory minimum, not a target. With tens of thousands of funds trying to get current at the same time, auditor capacity is the bottleneck. Booking at the last legal moment is how a fixable problem turns into another missed deadline.
The same framework sets the rest of the tempo: once appointed, the auditor's written requests for documents must be answered within 14 days (s 35C(2)), and the auditor then has 28 days from receiving everything relevant to issue the report (reg 8.03). Reconstructing several years of financials is what actually consumes the runway.
How to get current — the practical path
- Confirm the position. Search the fund on Super Fund Lookup and confirm with the ATO exactly which years are outstanding — trustees are often out by a year in either direction.
- Appoint a registered SMSF auditor immediately. Don't wait for a 45-day window that, for overdue years, has already closed. Engage now so the backlogged years can be scheduled in sequence.
- Rebuild the records. Each overdue year needs its own financials, bank data and market valuations at 30 June of that year. Valuation evidence for prior years is the single most common cause of delay.
- Lodge oldest first, then watch the refresh. Once the audits are done and the returns are in, the "Regulation details removed" flag lifts at the next twice-weekly update and shows on Super Fund Lookup the following business day — and rollovers and contributions can resume.
A late lodgement is a fixable problem, but only if you leave enough runway for the audit to happen properly. The trustees who get ahead of this treat it as a now job, not a deadline job.
