A complying superannuation fund is a regulated Australian super fund that meets the requirements of the Superannuation Industry (Supervision) Act 1993 (the SIS Act) and holds a Notice of Compliance from the Australian Taxation Office. That status is what unlocks the concessional 15% tax rate on contributions and investment earnings. A fund that loses it pays 45% instead, so compliance is the single biggest factor in how much of your retirement savings you keep.
What the SIS Act Requires
The starting point is structural. The trustee must elect to have the fund regulated under the SIS Act, and under section 19(5) that election is irrevocable. Once a fund is in the framework, it stays there, under the ongoing oversight of the ATO for self-managed super funds or the Australian Prudential Regulation Authority for larger funds.
The Three Residency Tests
To qualify as an Australian super fund, three conditions must be satisfied at all times during the financial year:
- The fund was established in Australia, or holds assets here.
- Central management and control ordinarily sits in Australia. A temporary absence of up to two years is allowed; a permanent shift of decision-making offshore is not.
- The active member test is met: either the fund has no active members, or Australian-resident active members hold at least 50% of the total market value of fund assets (or 50% of the amounts payable if those members left).
Fail any one, and the fund is treated as non-resident and cannot be complying.1Australian Taxation Office. Check Your SMSF Is an Australian Super Fund
The Sole Purpose Test
Section 62 requires trustees to maintain the fund solely to provide retirement or death benefits to members. Every activity, from choosing investments to paying benefits, must serve that purpose. The ATO looks at whether trustees negotiated for personal benefits from fund transactions, whether personal benefits influenced investment decisions, and whether a pattern of non-retirement benefits emerges over time. A small, unavoidable side benefit from an otherwise legitimate investment will not necessarily breach the test, but anything more deliberate will.2Australian Taxation Office. SMSFR 2008/2 – The Application of the Sole Purpose Test in Section 62 of the SISA
A Written Investment Strategy
Regulation 4.09 of the SIS Regulations requires a written investment strategy covering the risk and expected return of the fund’s investments, diversification, liquidity, the fund’s ability to meet current and future liabilities, and whether members should be covered by insurance. Trustees must review the strategy regularly and document each review.3AustLII. Superannuation Industry (Supervision) Regulations 1994 – REG 4.09
How a Fund Actually Becomes and Stays Complying
Being regulated is not the same as being complying. A newly registered fund starts life listed as “Registered” and only earns complying status once the ATO issues a formal Notice of Compliance after reviewing its annual return and audit. Until that notice arrives, the concessional tax rate is not available.4Australian Taxation Office. Super Fund Lookup Status for SMSFs
Every SMSF must be audited each year by an independent, registered auditor who examines both the financial statements and the fund’s compliance with the SIS Act and Regulations. The independence bar is strict: the auditor must be free from self-interest, self-review, familiarity, advocacy, and intimidation threats, and must document how they assessed each one.5Australian Taxation Office. Auditor Independence If the auditor finds a serious breach, they lodge an Auditor Contravention Report with the ATO.6Australian Taxation Office. Auditor/Actuary Contravention Report Instructions – Reporting Criteria
Lodging the SMSF annual return on time is non-negotiable. For the 2024–25 year, newly registered funds and funds with overdue returns must lodge by 31 October. Self-preparing funds that are up to date generally have until 28 February, and tax-agent lodgers may have until 15 May.7Australian Taxation Office. Know the Date Your SMSF Annual Return Is Due Miss the date by more than two weeks and the ATO removes the fund’s regulation details from Super Fund Lookup. APRA-regulated funds will not process rollovers to it, and the ATO recommends that employers stop contributing. Filing the overdue return restores the listing, with updates on Mondays and Wednesdays.4Australian Taxation Office. Super Fund Lookup Status for SMSFs
Checking the Status on Super Fund Lookup
Super Fund Lookup is the public registry employers and other funds use to check whether a super fund can receive contributions and rollovers. It covers both ATO-regulated SMSFs and APRA-regulated funds.8Australian Government Super Fund Lookup. Super Fund Lookup If your fund does not show the right status, money stops flowing in.
A fund can appear under one of five labels:
- Registered: regulated but not yet issued a Notice of Compliance or Non-Compliance. Rollovers and contributions can still be accepted.
- Complying: holds a Notice of Compliance, qualifies for the 15% rate, and can receive employer contributions that count toward the super guarantee.
- Non-complying: failed the residency conditions or received a Notice of Non-Compliance. Taxed at 45%, cannot receive rollovers, and employer contributions do not count as super guarantee payments.
- Regulation details withheld: the ATO has concerns and is investigating. Rollovers and contributions are effectively blocked.
- Regulation details removed: annual returns are overdue or the corporate trustee has been deregistered. Rollovers and contributions are effectively blocked until fixed.
Trustees should check their listing periodically to catch a problem before it interrupts contributions.4Australian Taxation Office. Super Fund Lookup Status for SMSFs
The Tax Rates You Get in Return
Complying status delivers a flat 15% tax rate on concessional contributions and investment earnings inside the fund. Concessional contributions include employer super guarantee payments, salary sacrifice, and personal contributions claimed as a deduction. Non-concessional contributions, which come from after-tax income, are not taxed again on entry.
The CGT Discount
On assets held for at least 12 months, a complying fund gets a one-third (33.33%) discount on capital gains. That brings the effective rate on long-term capital gains down to 10%. Capital losses must be offset against capital gains first, with the discount then applied to what remains.9Australian Taxation Office. CGT Discount
Retirement Phase Earnings Become Tax-Free
Once a member enters the retirement phase and the fund starts paying an income stream, earnings on assets supporting that pension are exempt current pension income and pay no tax at all.10Australian Taxation Office. Exempt Current Pension Income The general transfer balance cap for 2025–26 is $2 million, which limits how much a member can move into that tax-free retirement phase.11Australian Taxation Office. Transfer Balance Cap This is where complying status pays off most: a well-managed fund moves from 15% during accumulation to 0% on retirement-phase earnings.
What Happens If the Fund Loses Complying Status
A Notice of Non-Compliance is severe. In the year the notice is issued, the fund’s assessable income includes an amount equal to the market value of all fund assets, less any non-concessional contributions already taxed. That whole amount is taxed at 45%. For a fund with $800,000 in assets and $200,000 in previously taxed non-concessional contributions, $600,000 would be taxed at 45%, producing a tax bill of $270,000.12Australian Taxation Office. Our SMSF Non-Compliance Actions
The ATO weighs the seriousness of the breach, its effect on fund assets, the trustee’s efforts to fix it, the compliance history, and the circumstances behind the breach before going this far. The step is treated as a last resort, but trustees who repeatedly ignore obligations should not assume they will get a softer landing.12Australian Taxation Office. Our SMSF Non-Compliance Actions
Enforcement Short of Non-Compliance
Before that point, the ATO has other tools it uses to push trustees back on side. These escalate with severity:
- Education directions require a trustee to complete an approved SMSF education course, provide evidence of completion, and re-sign their trustee declaration within 21 days.
- Administrative penalties apply to specific breaches. Late lodgment attracts one penalty unit (currently $330) for every 28 days overdue, capped at five units. False or misleading statements attract 20 penalty units for carelessness up to 60 for intentional disregard of the law.
- Rectification directions require trustees to fix a specific breach within a set timeframe.
Education directions are often paired with a penalty, so a trustee who misunderstood the rules faces both a financial consequence and the knowledge to avoid repeating the mistake.13Australian Taxation Office. Supporting SMSF Compliance Through Education Directions
Voluntary Disclosure
If you find a breach before the ATO does, disclosing it voluntarily can reduce the response substantially. The ATO’s voluntary disclosure service lets trustees report the breach and propose a rectification plan. Disclosing before an audit begins is factored into the penalty decision, and the ATO generally will not open an audit off an Auditor Contravention Report if the issue is already being resolved through the service. You cannot use it once you have been notified of an ATO audit or review of the same matter.14Australian Taxation Office. SMSF Voluntary Disclosure Service
