Self Managed Super Fund: Rules, Costs and Trustee Duties

A self managed super fund (SMSF) is a superannuation fund you set up and run yourself, with you and the other members acting as trustees. Instead of an outside trustee choosing the investment menu, you decide the strategy, hold the assets in the fund's name and answer to the ATO for compliance. The ATO regulates SMSFs and states that an SMSF can have up to six members, and that generally each member must be a trustee or a director of the fund's corporate trustee.

This guide is for people weighing up whether to take on that job: employees with a decent balance who want direct control, couples pooling their retirement savings, and small business owners who want the fund to hold assets such as commercial property. It is also for anyone who already has a fund and wants to know what the trustee obligations actually involve day to day.

What you will get from this guide is a practical sequence rather than a sales pitch. We cover what the structure is, how contributions and investments flow through the fund, the trustee duties and the sole purpose test, the realistic cost picture and minimum balance question, how a self managed super fund compares with a large public offer fund, what changes when you add a partner or adult children, and how a fund is wound up when you no longer want to run it.

One boundary to set early: this is general information about how the rules work. It is not personal advice about whether an SMSF suits your circumstances, and the ATO is clear that trustees remain responsible for their fund's decisions even when they use professionals. Contributions caps, deduction rules for personal contributions and other superannuation tax settings sit alongside this topic, and our giving and super deduction guides deal with the claim side in more detail.

• A self managed super fund is a private fund you run as trustee, regulated by the ATO rather than APRA, with up to six members allowed.
• Every member must generally be a trustee (or a director of the corporate trustee), and trustees carry the legal responsibility for investment decisions, an annual audit and lodging the fund's annual return.
• The sole purpose test means the fund must be maintained to provide retirement, death or ill health benefits, which rules out using fund assets for present day personal benefit.
• Fixed running costs (audit, ASIC fees, the ATO supervisory levy, accounting) mean the cost per dollar of savings falls as the balance grows, so small balances face a proportionally higher fee drag.
• Winding up is a defined process: pay out or roll over benefits, complete a final audit and final return, then close accounts and cancel the ABN.

A self managed super fund is a trust set up for the sole purpose of providing retirement benefits to its members. It has its own trust deed, its own tax file number and ABN, its own bank account and its own investment strategy. The ATO administers the SMSF rules, while large public offer funds are prudentially supervised by APRA. That difference in regulator is the reason the compliance work lands on you.

The structural choice made at setup shapes the paperwork that follows.

The ATO's SMSF setup guidance covers both structures and the trustee declaration each new trustee must sign within 21 days of appointment.

Money enters a self managed super fund the same way it enters any fund: employer contributions under the super guarantee, salary sacrifice, personal contributions and rollovers from existing accounts. Contributions caps and the ATO's contribution acceptance rules apply regardless of fund type, and the fund must accept only amounts it is permitted to accept.

The fund then invests according to a written investment strategy that trustees must prepare and review regularly. The ATO expects that strategy to address risk, return, diversification, liquidity and whether to hold insurance for members. Assets must be held in the fund's name, kept separate from personal and business assets, and valued at market value each year for reporting.

On the way out, benefits can generally only be paid once a member meets a condition of release, such as reaching preservation age and retiring. Trustees pay benefits as a lump sum, an income stream or a combination, and must document the decision. Each year the fund needs an audit by an approved SMSF auditor before the annual return is lodged.

Trustee duties are set out in superannuation law and summarised in the ATO trustee declaration. You must act honestly in all matters, act in the best financial interests of all members, keep the fund's money separate from your own, and not enter arrangements that give a member or relative a present day benefit from fund assets. That last point is the practical edge of the sole purpose test: a holiday unit the family uses on weekends fails it, even if the fund bought it at market price.

Several specific restrictions catch new trustees:

• In house assets, such as loans to or investments in a related party, are generally capped at 5% of the fund's total assets.
• The fund cannot lend money or provide financial assistance to a member or a member's relative.
• Assets generally cannot be acquired from related parties, with limited exceptions including listed securities and business real property acquired at market value.
• Borrowing is restricted, with limited recourse borrowing arrangements the main permitted route.

Breaches can lead to the ATO issuing directions, imposing administrative penalties on each trustee personally, or treating the fund as non complying, which carries a heavy tax consequence.

The most common reason people stop short is time. Running a superannuation fund is an ongoing administrative job: maintaining minutes, tracking contributions against caps, reconciling the bank account, valuing assets, arranging the audit and lodging the annual return by the due date. Even with an accountant and an administrator engaged, trustees still sign off on the numbers.

The second reason is knowledge. Trustees need enough financial literacy to write and review an investment strategy, and enough legal awareness to spot a related party problem before the auditor does. There is no requirement to hold a qualification, which is precisely why the ATO puts the responsibility in writing at setup.

Three further hesitations deserve more weight than they usually get:

• Dispute resolution. Members of an APRA regulated fund can take complaints to the Australian Financial Complaints Authority. SMSF members generally cannot, so internal disagreements can end up in court.
• Compensation for fraud or theft. Commonwealth financial assistance for losses caused by fraudulent conduct is not available to SMSFs.
• Insurance and succession. Cover must be arranged deliberately, and a superannuation death benefit nomination needs to be valid and current for the outcome you expect.

There is no legislated minimum balance for a superannuation fund you run yourself. The practical constraint is fixed costs, which do not shrink with the balance.

Expect setup costs for the trust deed and, if you choose one, a trustee company registered with ASIC. Recurring costs typically include:

• The ATO SMSF supervisory levy, payable with the annual return.
• An independent audit by an approved SMSF auditor, required every year even for a simple fund.
• Accounting and administration to prepare financial statements and the annual return.
• ASIC annual review fees where a corporate trustee is used.
• Investment platform, brokerage, valuation and, if used, financial advice fees.

Do the arithmetic as a percentage. If fixed costs run to roughly $3,000 a year, that is about 1.5% of a $200,000 balance but around 0.4% of an $800,000 balance. ASIC has previously flagged that funds with low balances tend to be uncompetitive on cost against large funds, which is why the balance question is really a cost efficiency question. Note that fund expenses are generally deductible to the fund, not to you personally.

The trade off between a large public offer fund and a super fund SMSF structure is control against convenience. A large fund handles administration, audit, reporting, insurance and complaints handling, and members choose from a set investment menu. In a self managed fund you can hold direct shares, term deposits, business real property and other permitted assets, and you control the timing of buying and selling, which matters for capital gains and for pension phase planning.

Points that are easy to miss when comparing:

• Insurance in a large fund is often available on a group basis without individual underwriting, while an SMSF must buy cover on the open market.
• Franking credits and asset segregation can be managed member by member in an SMSF, but the same tax rules apply in both structures.
• Switching is not one way. You can hold an SMSF and a public offer account at the same time, which some members do to keep insurance in place.

An SMSF can have up to six members, so a couple, or parents and adult children, can share one super fund SMSF structure. Pooling balances spreads the fixed costs across more members and can make a lumpy asset such as commercial property achievable. It also lets a family run a single investment strategy rather than several.

The complications are governance ones. Every member is generally a trustee, so each has a say, and the trust deed decides how disputes are settled and whether votes are counted per head or by account balance. Practical questions to settle in writing before anyone joins:

• How decisions are made if trustees disagree, and what happens in a deadlock.
• How a member exits, including how assets will be valued and whether any must be sold.
• What happens on death, divorce or loss of capacity, including binding death benefit nominations.
• Whether members with different time horizons can hold different investment mixes within the fund.

Adding members also means updating trustee appointments, ASIC records for a corporate trustee, and asset titles where individual trustees are used.

Many trustees eventually decide the administration is no longer worth it, often well into retirement or after a member dies or loses capacity. Winding up is a defined process rather than simply closing the bank account. The trust deed sets out the steps, and the ATO expects trustees to:

• Deal with all fund assets, which usually means selling them or transferring them in specie where permitted.
• Pay out benefits to members who have met a condition of release, or roll the balances over to an APRA regulated superannuation fund.
• Obtain a final audit and lodge a final SMSF annual return, indicating it is the last return.
• Pay any outstanding tax, then close the fund's bank account and cancel its ABN and registrations.

Two timing traps are worth planning around. Selling assets can trigger capital gains tax inside the fund, so the sequence relative to pension phase matters. And a rollover generally cannot happen until the fund's reporting is up to date, so leaving the final return until the last minute can delay the transfer.

Eligibility is broad: most people can be a trustee, the fund can have up to six members, and each member generally must be a trustee or corporate trustee director. The calculation that decides whether it makes sense is a cost one, comparing fixed annual costs such as the ATO supervisory levy, audit and administration against your balance. Record keeping is the ongoing obligation: an investment strategy, trustee minutes, market valuations, an annual audit and the fund's annual return.

Is it worth having a self-managed super fund?

It depends on your balance, your interest in the job and the assets you want to hold. An SMSF is generally worth considering if the fixed annual costs are a small percentage of your balance, you want direct control over specific assets, and you are willing to act as trustee and sign off on the fund's compliance every year. It is usually not worth it if you would outsource every decision anyway, because you keep the legal responsibility without gaining the control.

What is the 5 rule for SMSF?

People usually mean the in house asset rule. Under superannuation law, a fund's in house assets, broadly loans to or investments in related parties and assets leased to related parties, cannot exceed 5% of the fund's total assets measured at market value. Business real property leased to a related party is an important exception and is not counted as an in house asset when the conditions are met. Trustees also apply a 5% type test in practice at year end, because exceeding the limit requires a written plan to reduce the holding.

Can a doctor help with self managed super fund?

A doctor cannot help with the fund itself. Medical practitioners are relevant in two narrow situations: supporting an early release of benefits on the grounds of permanent incapacity or terminal medical condition, and providing evidence where a member has lost the capacity to act as trustee. For the fund's setup, strategy and compliance you need appropriately licensed and registered professionals, such as a financial adviser, an SMSF accountant and an approved SMSF auditor.

How much super do you need for a self-managed fund?

There is no legal minimum. The workable answer comes from dividing your expected fixed costs by your balance. As a rule of thumb, a lower balance carries a higher percentage cost, and ASIC has cautioned that small funds can be uncompetitive against large funds on fees alone. Consider also whether future contributions and pooled member balances will lift the fund's scale within a few years.

What is the best self-managed super fund in Australia?

We do not rank funds, and no single structure suits everyone. A self managed super fund is a structure you run rather than a product you buy, so the useful comparison is between your own likely costs, investment plans and available time and what a large public offer fund already provides. Use the ATO's SMSF material for the rules and obtain licensed advice for the decision.
