Quick Answer
What are the mandatory compliance requirements for an SMSF in 2026?
Every SMSF must complete an independent annual audit, lodge an SMSF annual return with the ATO (usually by October 31), maintain a documented investment strategy, pay the ATO supervisory levy ($259 in 2026), and keep records for 5–10 years. All trustees must have signed the ATO trustee declaration. The biggest ongoing compliance risks for property investors are the sole purpose test (no personal use of SMSF property), related party transaction rules, and the in-house asset limit (max 5% in related party assets).
The Annual SMSF Compliance Checklist
Use this checklist to ensure your SMSF meets all ATO obligations each financial year. Your SMSF accountant will handle most of these, but trustees remain personally responsible for compliance.

The Sole Purpose Test: The Most Important Rule
The sole purpose test is the foundation of all SMSF compliance. It requires that an SMSF be maintained solely for the purpose of providing retirement benefits to its members, or to their dependants in the case of a member's death.
In practice, for property investors, this means the SMSF property must be held as a genuine investment — not used for personal benefit by members, their family, or any related parties. The test is applied to the intent and outcome of investment decisions, not just their form.
What Breaches the Sole Purpose Test
- Living in your SMSF investment property — even temporarily, even if you pay rent
- Letting family members live in the property — even at market rent
- Using the property for personal holidays or short-stay accommodation for yourself
- Making investment decisions to provide a current personal benefit rather than retirement benefit
- Renting the property to any related party for residential purposes
The Exception: Business Real Property
Business real property (commercial property used entirely in a business) is exempt from some related party restrictions. Your SMSF can purchase your own business premises and lease it back to your business — provided it is leased at genuine market rates with a formal lease agreement. This is a legitimate and commonly used SMSF strategy for small business owners. Residential property does not qualify for this exemption.
Important: The ATO can look back years to find breaches
The ATO has sophisticated data matching and can look back multiple years when investigating SMSF compliance. A sole purpose test breach from 3 years ago can still be pursued and result in the fund being retrospectively declared non-complying, triggering massive back-taxes. Don't assume an undiscovered breach is a safe breach.
The Annual Audit: What the Auditor Actually Checks
Every SMSF must undergo an annual audit by an ATO-registered SMSF auditor who is independent of the fund. Your accountant arranges this. The audit has two components: a financial audit and a compliance audit.
The Financial Audit
The financial audit verifies that the fund's financial statements are accurate — that assets are correctly valued, income is correctly recorded, and expenses are legitimately fund-related. For a property-holding SMSF, the auditor will check:
- Property valuation: must reflect current market value as at 30 June
- Rental income: must match bank records and lease agreements
- Loan balance (LRBA): must match lender statements
- Property expenses: must be properly documented with receipts
- Separation of SMSF and personal finances: no commingling
The Compliance Audit
The compliance audit checks that the fund has operated within the SIS Act rules. For a property-holding SMSF, key compliance areas checked include:
- Sole purpose test compliance — no personal use of property
- Investment strategy: documented, up to date, and followed
- Trustee declarations: signed by all trustees
- Related party transactions: arm's length and compliant
- In-house assets: within the 5% limit
- LRBA structure: properly documented bare trust
- Contribution limits: no excess contributions received
What Happens When the Auditor Finds a Problem
If the auditor finds a minor issue (a documentation gap, a slightly late trustee declaration), they will typically issue a qualified audit report and give the trustees opportunity to rectify. If the issue is more serious — particularly a prohibited transaction or a sole purpose test concern — the auditor is legally required to lodge an Auditor Contravention Report (ACR) with the ATO, regardless of whether you've fixed it.
Once an ACR is lodged, the ATO investigates. Depending on the severity, consequences range from administrative penalties ($1,260–$12,600 per trustee per breach) to fund disqualification (entire balance taxed at 47%). Regularity and severity of breaches determines the ATO's response.
Property Valuation Requirements
SMSF-owned property must be valued at market value as at 30 June each year for the financial statements. This is not optional — understating or overstating property values creates compliance problems.
What Counts as an Acceptable Valuation?
The ATO does not require a full formal valuation every year. Acceptable evidence includes: a formal valuation by a licensed property valuer, a recent comparable sales analysis, a kerbside assessment from a licensed real estate agent, online valuation tools (CoreLogic, Domain) with supporting comparable sales data, or council rate valuations. Your auditor decides what evidence is sufficient — provide something objective rather than just the trustees' own opinion.
In years where property values have moved significantly (up or down), or if the property is being used as a basis for related party transactions, a formal valuation from a licensed valuer is strongly recommended. Cost: $500–$1,500 for a standard residential property.
Pro Tip: Get formal valuations for related party commercial leases
If your SMSF owns commercial property leased to your business, the ATO pays close attention to whether rent is at market value. Get a formal market rent assessment from a licensed commercial property agent every 1–2 years and keep the documentation. Charging below-market rent to your business is a related party benefit — a clear compliance breach.
Investment Strategy: What Compliance Requires
Having an investment strategy is legally mandatory under Section 52B of the SIS Act. The strategy must be in writing, must be reviewed regularly, and must address specific matters.
What Your Investment Strategy Must Address
- Risk and likely return: the expected return from property and how it fits the members' risk profile
- Diversification: how the fund balances property against other assets (or justifies concentration in property)
- Liquidity: how the fund will meet expenses, pensions, and member benefits when they fall due — particularly important when holding illiquid property
- Insurance: whether each member's insurance needs are considered within the strategy (even if you decide not to hold insurance in the fund)
- Ability to discharge liabilities: including any LRBA repayments and ongoing fund costs
Your strategy should be specific to your fund's situation — not a generic template. Auditors increasingly require evidence that the strategy has been genuinely considered. Update it when members' circumstances change, when you acquire or sell property, or when the borrowing arrangement changes.
Record Keeping Requirements
Poor record keeping is the most common reason minor compliance issues become major ones. The ATO can request records from SMSF trustees at any time — and cannot verify your fund's compliance without them.
SMSF Record Retention Requirements
Minimum retention periods by document type
| Document Type | Minimum Retention | Storage Requirement |
|---|---|---|
| Financial statements & tax returns | 5 years | Secure (digital OK) |
| Bank statements & receipts | 5 years | Secure (digital OK) |
| Trustee declarations | 10 years | Original preferred |
| Minutes of trustee meetings/decisions | 10 years | Signed originals |
| Original trust deed | Indefinitely | Original document |
| All trust deed amendments/variations | Indefinitely | Original documents |
| Member benefit payment records | 10 years | Secure (digital OK) |
| LRBA loan documentation | 5 years after loan repaid | Secure (digital OK) |
Store original trust deeds and deed variations extremely carefully — in a fireproof safe, with a solicitor, or via a specialist document storage service. If your original trust deed is lost or damaged, reconstituting it can cost $5,000–$15,000 in legal fees and creates serious compliance complications.
Prohibited Transactions and Related Party Rules
Related party transaction rules are the second most common source of SMSF compliance breaches after the sole purpose test. Know these rules precisely — they are strictly applied.
The In-House Asset Rule (5% Limit)
Your SMSF cannot invest more than 5% of its total assets in "in-house assets" — loans to, or investments in, related parties of the fund. Related parties include members, their relatives, companies controlled by members, trusts associated with members, and employers of members.
If you breach the 5% limit (for example because property values have changed the ratio), you have 12 months to bring it back within the limit. You cannot make new in-house asset investments if you are already at or above 5%.
Prohibited Transactions: What You Can Never Do
Some transactions are absolutely prohibited regardless of circumstances:
- Lending money to members or their relatives from the SMSF
- Acquiring assets from a related party (other than listed securities at market value, or business real property at market value)
- Providing financial assistance to members using fund assets
- Charging a higher price for assets sold to related parties (or buying at below market value from related parties)
Event-Based Reporting (EBR) Requirements
Certain significant events must be reported to the ATO within 28 days of occurrence. For property-holding SMSFs, key events include: commencing a pension (must report each pension commencement), receiving a commutation of pension, making a structured settlement contribution, and trustee becoming disqualified. Failing to report on time attracts penalties and can cause downstream issues with transfer balance cap calculations.
What Happens When Compliance Is Breached
The consequences of SMSF compliance breaches scale rapidly from minor administrative penalties to catastrophic fund-level consequences.
SMSF Compliance Breach Consequences
Penalty scale based on breach type and severity
| Breach Type | ATO Response | Typical Cost |
|---|---|---|
| Late trustee declaration | Administrative penalty | $1,260/trustee |
| Inadequate investment strategy | Administrative penalty | $1,260/trustee |
| Late event-based reporting | Administrative penalty | $1,260–$3,150/trustee |
| Minor investment rule breach | Education direction + penalty | $2,520–$12,600/trustee |
| Related party transaction breach | Penalty + possible disqualification | $12,600/trustee + legal costs |
| LRBA structuring error | Fund rectification required | $10,000–$30,000 to rectify |
| Sole purpose test breach | Non-complying fund declaration | 47% tax on entire balance |
Important: Non-complying status is devastating
If an SMSF is declared non-complying, its entire taxable component is taxed at 47% in that financial year. A fund with $700,000 in accumulated assets would face a tax bill of approximately $329,000 — destroying nearly half the fund's value in one year. This is the worst-case outcome of SMSF compliance failure, and it can happen for a single serious breach.
ATO Audit Triggers: What Gets SMSF Trustees Flagged
The ATO uses data matching, auditor contravention reports, and its own analytical tools to identify SMSF funds at higher risk of compliance issues. Understanding what triggers ATO attention helps you manage your fund in a way that minimises scrutiny.
Auditor Contravention Reports (ACRs)
The most direct trigger for ATO investigation is an Auditor Contravention Report. When your annual SMSF auditor identifies a compliance breach and lodges an ACR, the ATO reviews it. The frequency and nature of ACRs from a given fund determines whether the ATO takes passive or active interest. A single minor ACR may generate an ATO letter. Repeated ACRs or a serious breach will trigger a formal compliance review.
In the 2023-24 financial year, the ATO received over 22,000 ACRs from SMSF auditors. The most common breach types reported were: investments not consistent with investment strategy (29%), sole purpose test concerns (18%), in-house asset rule breaches (16%), and related party transaction issues (14%). Property-related compliance is a significant proportion of all ACRs.
ATO Data Matching
The ATO matches SMSF data against external sources including: land registry records (checking property ownership against related parties), rental income declared on the SMSF annual return vs property address information, transfer balance cap records (pension phase reporting), and member TFN contribution records (checking for excess contributions). Data matching catches situations where the SMSF has relationships with properties or people that should be arm's-length but aren't.
Late Lodgment of Annual Returns
Consistently late SMSF annual return lodgments are a reliability flag. The ATO's systems identify funds that regularly lodge late and may direct more scrutiny to those funds' compliance generally. Always lodge by the due date (or via your tax agent's lodgment program which provides extended deadlines). If you know you will be late, contact the ATO proactively — late lodgment combined with no communication is worse than late lodgment with an explanation.
Unusual Fund Transactions
The ATO's analytics flag certain transaction patterns as higher risk: large cash transfers from the SMSF to related entities without clear investment purpose, property transactions where the counter-party shares a postcode or entity type with fund members, and funds where the declared property value in the annual return stays unchanged year over year (suggesting the valuation is not being genuinely updated).
Voluntary Disclosure: What to Do When You've Made a Mistake
Every SMSF trustee should know about the ATO's voluntary disclosure process. If you have made a compliance mistake — even a serious one — coming forward proactively almost always results in better outcomes than being discovered.
The ATO's Approach to Voluntary Disclosure
The ATO's SMSF compliance framework explicitly provides for reduced penalties and more cooperative outcomes when trustees self-identify and report compliance issues. Under the ATO's penalty framework, voluntary disclosure before an audit commences typically results in penalties remitted to 25–50% of the standard amount. Disclosure after an audit starts but before formal findings can still reduce penalties by 25%. The key principle: the ATO prefers compliance correction over punishment, and trustees who engage cooperatively and remediate issues receive better outcomes than those who resist.
How to Make a Voluntary Disclosure
Voluntary disclosures are made through the ATO's Online Services for Business portal or through your registered tax agent. Before disclosing, work with your SMSF accountant to: clearly identify the breach, understand its legal characterisation under the SIS Act, assess its impact on the fund's compliance status, and ideally remediate it before disclosure (or have a clear remediation plan). The ATO's response depends heavily on whether the breach was unintentional, isolated, and whether it has been fixed or is being actively fixed.
Pro Tip: Don't wait for your auditor to find it
If you become aware of a compliance issue during the year — before your annual audit — tell your SMSF accountant immediately. Issues resolved before the audit are far easier to manage than issues discovered during it. Your auditor must report certain breaches to the ATO regardless, but the difference between "we identified this issue and rectified it before audit" versus "the auditor found this unresolved issue" is significant in terms of the ATO's response.
When to Seek Specialist SMSF Legal Advice
For serious compliance breaches — sole purpose test violations, significant related party transactions, potential NALI issues — you should engage a specialist SMSF lawyer before making any disclosure or communicating with the ATO. Legal professional privilege protects communications with your lawyer, whereas communications directly with the ATO or through your accountant are not privileged. In serious cases, having a lawyer manage the disclosure process can protect your position significantly.
SMSF Compliance — Frequently Asked Questions
Frequently Asked Questions
There are two levels of consequence. Minor issues flagged by the auditor (like a late trustee declaration or a documentation gap) result in the auditor lodging a reportable compliance breach with the ATO. The ATO may issue administrative penalties of $1,260–$12,600 per trustee per breach. Serious breaches — like the sole purpose test violation or a related party transaction — can cause the fund to be declared 'non-complying,' which means your entire SMSF balance is taxed at 47% in that financial year. We've seen $600,000 funds hit with $282,000 tax bills.
The SIS Act requires trustees to regularly review the investment strategy — but doesn't define a specific frequency. The ATO's expectation is at minimum annual review, and the strategy must be updated whenever members' circumstances change significantly: a member approaches retirement, the fund acquires a new property, member balances shift materially, or there's a significant market event. Your SMSF auditor reviews the strategy every year — a strategy that hasn't been touched in 3+ years will get flagged, even if it's technically still compliant.
This is a very common scenario and it's actually fine — if you do it correctly. You can reimburse yourself from the SMSF for legitimate SMSF expenses you paid personally (like a council rates bill you paid from your personal account while waiting for SMSF funds to arrive). The key requirement: the expense must be genuinely an SMSF expense, you must have documentation proving you paid it, and the reimbursement must happen promptly — not months or years later. Extended delays can make it look like an illegal financial assistance arrangement.
Minimum retention periods: 5 years for most financial records (bank statements, receipts, tax returns, financial statements, rental income records). 10 years for trustee declarations, minutes of trustee meetings, written consent of members, and documents that alter the trust deed. Indefinitely for the original trust deed and all deeds of variation — these are the foundation documents of the fund. Store original documents safely (not just digital copies) — auditors and the ATO can request originals, and courts have ruled against funds that couldn't produce originals.
There's no explicit requirement in the SIS Act for trustee meetings — but your trust deed almost certainly requires them, and your auditor will expect documented decisions. In practice, you need written trustee resolutions (minutes) for major decisions: acquiring or disposing of property, changing the investment strategy, commencing a pension, accepting a new member, approving financial statements. Verbal decisions that aren't documented create compliance problems — your auditor cannot verify an undocumented decision. Keep a simple meeting minutes file — it takes 30 minutes per year and prevents audit headaches.
The in-house asset rule limits the amount of fund assets that can be invested in related parties to 5% of the fund's total assets. A 'related party' includes members, relatives of members, employers of members (if the SMSF is related), and certain companies or trusts associated with members. For property, this means your SMSF cannot lend money to related parties, and cannot own an interest in a property that is partly owned by a related party (unless it's business real property under specific conditions). If you breach the 5% threshold, you have 12 months to rectify it — but penalties apply.
