Running your own super fund feels like the smart move until the first audit lands, the contribution caps shift again, the rules change, and you realise the structure you set up three years ago no longer fits the way you actually invest. Plenty of trustees reach this point. The fund is compliant on paper, the returns are reasonable, but the tax bill keeps creeping up and nobody can quite explain why.
So how do you know if your SMSF is leaking money to the ATO that it shouldn't be?
When you set up a self-managed super fund, the conversation tends to focus on the exciting parts. Property inside super. Direct shares. Control over asset allocation. The flexibility to choose your own investments. What gets glossed over is the boring middle bit, where most of the tax inefficiency hides.
If any of those made you pause, you're not alone. The rules around super change often enough that even trustees who read the ATO updates struggle to keep pace. Getting tax advice on your SMSF from someone who specialises in this area, rather than a general accountant who handles a couple of funds on the side, tends to surface savings most trustees didn't know were available.

Part of the answer is timing. The ATO doesn't fine you for missing an opportunity, so missed opportunities don't show up on any compliance report. They just quietly cost you money year after year.
Take pension phase as one example. Once you hit preservation age and meet a condition of release, you can start an account-based pension from your SMSF. Earnings on the assets backing that pension become tax-free, up to the transfer balance cap. Trustees who delay starting a pension because the paperwork feels daunting often pay 15% on earnings they could have been receiving tax-free for years.
Another common one is asset segregation. If your fund holds a mix of pension and accumulation accounts, the way assets are pooled or segregated affects how capital gains are taxed. Get it right and gains on pension assets are exempt. Get it wrong and you pay tax that could have been avoided entirely.
Then there's the timing of contributions. Making a personal deductible contribution in June rather than July can shift tens of thousands of dollars in deductions from one financial year to another. Useful if you've had a high-income year. Less useful if it pushes you over a cap and triggers excess contributions tax.

Property is where things get genuinely complicated. Limited recourse borrowing arrangements, in-house asset rules, related-party transactions, the sole purpose test. Each of these has tripped up funds that looked perfectly fine until an auditor started asking questions.
The sole purpose test is probably the most misunderstood. Your fund exists to provide retirement benefits to its members. It doesn't exist to provide a holiday house, a workshop for your business, a storage shed, or a property your adult children can rent at mates' rates. Auditors are increasingly looking at whether trustees treat fund assets as personal assets, and the penalties for getting this wrong are severe enough to wipe out years of tax savings.
If you've borrowed to buy property inside your SMSF, the loan terms also need ongoing review. Interest rates move, refinancing rules apply differently to SMSF loans, lender appetites shift, and what was a sensible structure in 2020 might be costing you significant interest in 2026.

Every SMSF needs an independent audit each year. Most trustees treat this as a tick-box exercise. The auditor signs off, you pay the fee, and life moves on until next year.
The trouble is that auditors are required to report contraventions to the ATO once they spot them. A fund that's been quietly non-compliant for several years can suddenly find itself dealing with breach notices and administrative penalties, or in worst cases, the loss of complying fund status. A non-complying fund pays tax at 45% instead of 15%. That's not a typo.
This is why having someone review your fund before audit season matters. Issues caught in May can often be fixed before year-end. Issues caught in October by the auditor become formal contraventions.

If you already have an accountant looking after your SMSF, a few questions can quickly reveal whether you're getting genuine specialist support or just basic compliance work:
How many SMSFs does the firm currently administer? When did they last review your fund's investment strategy document, and was it updated to reflect any changes in your asset mix? Have they walked you through your transfer balance cap position? Do they proactively contact you about contribution timing before year-end, or only after you've already made the contribution?
The answers tell you a lot. A specialist SMSF practice will have systems for tracking these things across hundreds of funds. A general accountant treating your SMSF as one of fifteen miscellaneous client jobs probably won't.

docAlpha provides centralized monitoring and intelligent workflow automation for tax-related documents, approvals, and financial records. Improve transparency, reduce missed deadlines, and support more responsive tax operations.
If your fund balance is growing, your circumstances have changed, you're approaching pension phase, or you've taken on more complex assets, a fresh review tends to pay for itself many times over. Same goes if you've recently inherited assets, sold a business, restructured your work arrangements, or are thinking about contribution strategies in the lead-up to retirement.
The cost of a proper SMSF review sits somewhere between a few hundred and a few thousand dollars depending on fund complexity. The cost of getting it wrong, whether through missed deductions, contribution cap breaches, compliance failures, or excess contributions tax, runs into tens of thousands. The maths usually works out in favour of asking.
Your super is probably your second-largest asset after your home. Worth checking it's being managed as carefully as you'd manage anything else of that value.
