What is an SMSF, and when does it actually make sense?

A self-managed superannuation fund is a superannuation fund that you run yourself. Instead of your retirement savings sitting in a fund managed by an institution, you become a trustee, and you decide how the money is invested.

That is the appeal, and it is a genuine one. It is also the entire source of the complication, because the control comes attached to legal responsibility that does not transfer to anyone else — including your adviser, accountant, or auditor.

This article covers how an SMSF works, what you take on as a trustee, what it costs to run, and the circumstances in which the structure tends to make sense or not.

How an SMSF differs from a public offer fund

In an APRA-regulated fund — an industry or retail fund — you are a member. You choose from a menu of investment options, and a professional trustee makes the decisions within them.

In an SMSF, you are the trustee. The fund can have up to six members, and every member must generally be a trustee (or a director of the corporate trustee). The fund is regulated by the Australian Taxation Office rather than APRA, and it must be maintained for the sole purpose of providing retirement benefits to its members.

The practical difference is not the range of investments. Many public offer funds now allow direct shares and term deposits. The difference is that in an SMSF, the investment strategy, the compliance, the record-keeping and the consequences of getting any of it wrong are yours.

What you are legally responsible for as a trustee

This is the part that deserves the most attention before anything else, because it is where the real cost of an SMSF sits — and it is not primarily financial.

According to the ATO, your obligations as a trustee include:

• Keeping up to date with superannuation and income tax law as it changes

• Developing, implementing and regularly reviewing an investment strategy

• Arranging an independent audit of the fund each year

• Valuing all of the fund’s assets at market value annually

• Keeping records, including minutes documenting trustee decisions

• Preparing financial statements and lodging the SMSF annual return

The single most important point, in ASIC’s own words on MoneySmart: trustees are always legally responsible for the fund’s decisions, even if you use an adviser, accountant or lawyer.

You can delegate the work. You cannot delegate the accountability. If the fund breaches the rules, the ATO’s compliance action is directed at the trustees. That can include penalties, and in serious cases the fund losing its concessional tax treatment — an outcome expensive enough to overwhelm any benefit the structure was set up to deliver.

Anyone considering an SMSF should be comfortable with that allocation of risk before going further. If it sounds like something you would rather not carry, that is a legitimate and sensible answer, and it points toward a public offer fund.

What an SMSF costs

Costs vary considerably depending on the fund’s assets, complexity and how much of the administration is outsourced, so any single figure quoted as typical is worth treating with suspicion. What can be said reliably is what the unavoidable cost categories are.

The ATO and MoneySmart identify these recurring costs:

• The annual ATO supervisory levy

• An annual independent audit, which is mandatory

• Accounting, tax and administration fees

• ASIC fees where a corporate trustee is used, including an annual review fee (lower where the company acts solely as a super fund trustee)

• Investment fees on whatever the fund holds

• Insurance premiums, where the fund holds cover for members

• Actuarial fees, where the fund pays certain pensions

• Legal and advice fees as required

A point that is frequently misunderstood: establishment costs are capital expenses and the fund cannot claim a deduction for them. If you pay the setup costs personally, regulation 5.02 of the Superannuation Industry (Supervision) Regulations 1994 allows the fund to charge those costs against your super benefits, meaning you can seek reimbursement from the fund.

Why balance size matters more than the headline cost

Several of these costs are largely fixed. The audit, the levy and the base administration fee cost roughly the same whether the fund holds $200,000 or $2 million.

MoneySmart puts the consequence plainly: the lower the SMSF’s starting balance, the greater the impact of fixed costs on overall returns. A fixed annual cost that is a rounding error on a large balance can be a material drag on a small one.

You will see specific minimum balances quoted widely as the threshold below which an SMSF is not viable. Be careful with those numbers. ASIC’s MoneySmart does not publish a minimum balance figure, and the right threshold genuinely depends on what the fund holds, how much administration is outsourced, and what the alternative fund would have charged. The useful exercise is not comparing your balance to a rule of thumb, but comparing your projected total annual SMSF cost — as a percentage of the balance — against the fee you would pay in a public offer fund for a comparable portfolio.

When an SMSF tends to make sense

An SMSF is a structure, not a strategy. It earns its cost when the structure itself does something a public offer fund cannot. The situations where that is genuinely true tend to share certain features:

Assets a public offer fund will not hold. Direct commercial property is the clearest example. An SMSF can own business real property, including — subject to strict conditions — premises leased to a member’s own business. This is a common and legitimate reason for business owners to establish a fund.

Genuine control over asset selection and timing. For investors with a specific investment approach, the ability to decide precisely what is held and when positions change can matter more than the cost differential.

Estate planning requirements. SMSFs allow greater precision in how death benefits are directed, which can matter in blended families or where a business succession plan interacts with superannuation.

Multiple members pooling balances. Because many costs are fixed per fund rather than per member, a fund with several members — a couple, or a family — may spread those costs across a larger asset base.

A balance large enough that fixed costs are immaterial, combined with a genuine willingness to take on trustee duties.

When it usually does not

• The primary motivation is a belief that you will outperform, without a specific strategy the structure enables

• The balance is small enough that fixed costs are a meaningful percentage drag

• Nobody involved wants to take on the compliance, record-keeping and annual audit

• The attraction is access to a particular investment that a public offer fund could actually provide

• You would be relying on an adviser so completely that the “self-managed” element is nominal — in which case you carry the trustee liability without exercising the control it is meant to buy

Questions worth asking before you set one up

1. What is the projected total annual cost of running the fund, itemised, and what percentage of the balance is that?

2. What would the equivalent portfolio cost inside a public offer fund?

3. What specifically will the SMSF let us do that a public offer fund will not?

4. Who prepares the investment strategy, and how often is it reviewed?

5. Individual or corporate trustee, and what are the cost and control implications of each?

6. What happens on the death or incapacity of a member or trustee?

7. What insurance cover do members currently hold, and would it be lost on rolling out of an existing fund?

That last question is often overlooked and occasionally expensive. Insurance held inside an existing superannuation fund may not be replaceable on the same terms, particularly where a member’s health has changed since the original cover was underwritten.

Where advice fits

An SMSF is one structure among several, and it is not a decision that should be made on the strength of the control argument alone. The relevant analysis compares the total cost of the structure against what it actually enables, alongside the trustee obligations the members would be accepting.
