Key Takeaways

  • An SMSF is a private Superannuation fund regulated by the ATO that you run yourself, with up to six members who are usually also the trustees.
  • Trustees are legally responsible for all decisions, including Investment strategy, compliance, record keeping and the annual audit.
  • SMSFs must meet the sole purpose test, lodge an annual return, pay the ATO supervisory levy (currently $259 for continuing funds) and be audited each year by an ASIC-registered SMSF auditor.
  • Running an SMSF involves real costs, including setup fees, ongoing administration, audit, ASIC fees for corporate trustees, and investment-related expenses.
  • An SMSF is not suitable for everyone. Investors should compare it with retail, industry and wrap super Options, and seek licensed professional advice.

For many Australians, superannuation is the largest financial asset they will ever own outside of the family home. While most people leave their retirement savings inside an APRA-regulated retail or industry super fund, a growing number are asking a different question: how does an SMSF work, and could a self-managed super fund give them more visibility and control over how their money is invested? According to the Australian Taxation Office (ATO), there are now more than 653,000 SMSFs in Australia, holding more than $1 trillion in Assets across roughly 1.2 million members. That makes the SMSF sector one of the largest segments of the country’s $4 trillion super system.

This guide explains how a self-managed super fund actually works, what trustees are required to do, what the ATO expects, and the costs and risks that every Australian should understand before deciding whether an SMSF could be relevant to their circumstances.

What Is an SMSF?

A self-managed super fund (SMSF) is a private superannuation fund that you set up and run for the benefit of yourself and, where relevant, other members. Unlike retail or industry funds that are regulated by the Australian Prudential Regulation Authority (APRA), SMSFs are regulated by the ATO. They can have between one and six members, and in most structures every member must also be a Trustee or a director of a corporate trustee.

In simple terms, an SMSF is your own super fund. You decide how the money is invested, within the boundaries of superannuation law. You also accept full legal responsibility for running it in line with the Superannuation Industry (Supervision) Act 1993 (SIS Act) and ATO guidance.

How Does an SMSF Work in Practice?

Understanding how an SMSF works means understanding the lifecycle of the fund, from the moment it is established to the day it is wound up. A typical SMSF moves through several stages.

Establishment

You decide on the trustee structure (individual trustees or a corporate trustee), choose a fund name, prepare and sign a trust deed, and apply for an Australian Business number (ABN) and tax file number (TFN) with the ATO. You then open a dedicated bank account in the name of the fund and, where relevant, an investment trading account.

Rollovers and contributions

Once the fund is registered, members can roll over existing super balances from other funds and make new contributions, subject to the concessional and non-concessional contribution caps set by the ATO. Employers can also make superannuation guarantee contributions directly into the SMSF, using SuperStream-compliant processes.

Investment

Trustees prepare and follow a written investment strategy that considers risk, return, Diversification, Liquidity, the ability to pay benefits and the insurance needs of members. The fund can invest in shares, managed funds, Exchange-traded funds (ETFs), term deposits, residential or commercial property, certain types of collectables and other assets allowed under super law. All investments must be made on commercial terms, separated from members’ personal assets, and managed for the sole purpose of providing retirement benefits.

Ongoing administration

Trustees keep accurate records, value assets at Market Value each year, lodge an annual SMSF return with the ATO, pay the supervisory levy and arrange an annual audit by an independent ASIC-registered SMSF auditor. Many trustees engage an SMSF administrator, Accountant and tax agent to handle the technical work.

Pensions and wind-up

When members reach the relevant preservation age and meet a condition of release, the fund can start paying pensions. Eventually, the SMSF will be wound up, with assets either paid to beneficiaries or rolled to another super fund, and a final return lodged with the ATO.

Trustee Structures: Individual vs Corporate

A core part of how an SMSF works is the choice of trustee structure. There are two main options.

Individual trustees

Every member must be a trustee, and every trustee must be a member. For a fund with two members, you would have two individual trustees. This structure is generally cheaper to set up but involves more paperwork if membership changes, because assets must be re-registered into the new trustees’ names.

Corporate trustee

A company acts as trustee, and every member is a director of that company. This structure has higher upfront and ongoing costs, including ASIC registration and annual review fees, but offers cleaner separation of personal and fund assets, easier handling of membership changes and clearer Liability boundaries. ASIC charges a special-purpose company an annual review fee that is significantly lower than that for a standard company.

The right structure depends on personal circumstances, succession planning and cost tolerance. Trustees should compare both options and seek professional advice before deciding.

Sole Purpose Test and Investment Strategy

Every SMSF must satisfy the sole purpose test. This means the fund must be maintained solely to provide retirement benefits to members or, in the event of a member’s death, to their dependants. It cannot be used to give a current-day benefit to members or related parties, such as living in a property owned by the fund or using fund assets for personal enjoyment.

Trustees must also prepare and regularly review a written investment strategy. The strategy must consider:

  • The risk and likely return from the fund’s investments.
  • The composition and diversification of investments.
  • The liquidity of investments and the fund’s ability to discharge liabilities.
  • The insurance needs of members.

The ATO has made it clear that a “set and forget” investment strategy is not acceptable. Trustees should document why each major asset is held, review the strategy after significant events, and keep evidence that the strategy is being followed in practice.

ATO Rules, Compliance and the Annual Audit

The ATO is the regulator of SMSFs and publishes detailed guidance on trustee obligations. Trustees must:

  • Lodge an annual SMSF return covering income tax, regulatory information and member contributions.
  • Pay the SMSF supervisory levy, which has been $259 per year for continuing funds (with $518 typically payable in the first year as the levy is paid one year in advance).
  • Arrange an annual audit by an independent SMSF auditor registered with ASIC. The auditor reviews both the fund’s financial statements and its compliance with super law.
  • Keep records for prescribed periods (generally five years for accounting records and ten years for trustee minutes and certain decisions).
  • Use a SuperStream-compliant electronic service to receive contributions and rollovers.

If the fund breaches super law, the ATO can apply administrative penalties, education directions, rectification orders or, in serious cases, disqualify trustees and make the fund non-complying, which can result in the loss of significant tax concessions.

Costs of Running an SMSF

Costs are a key reason many Australians decide an SMSF is not for them. While fees vary widely, typical expenses can include:

  • Setup costs, often between $800 and $3,500 depending on whether a corporate trustee and tailored trust deed are used.
  • Annual administration and accounting fees, commonly between $1,500 and $3,500 for online or low-touch services and higher for fully advised funds.
  • The independent audit fee, often several hundred dollars per year.
  • The ATO supervisory levy of $259 per year for continuing funds.
  • ASIC fees for corporate trustees (an annual review fee applies; the rate for special-purpose companies is significantly lower than for standard companies).
  • Investment costs such as brokerage, managed fund fees, ETF management costs and property-related expenses.
  • Optional advice fees from a licensed financial adviser.

Moneysmart and the ATO have both noted that SMSFs with low balances can be relatively expensive to run as a percentage of assets, which is one reason regulators urge careful comparison with APRA-regulated funds.

Why It Matters

The question of how an SMSF works is more than a technical one. It speaks to a much bigger issue: how much control Australians want over their retirement savings, and how much responsibility they are willing to take on to get that control. For some investors, the ability to choose specific shares, hold direct property, run a transition-to-retirement strategy or invest in unlisted assets is highly attractive. For others, the time, complexity and personal liability involved outweigh the potential benefits.

With the SMSF sector continuing to grow, and the ATO publicly signalling closer attention to trustee decision-making, record keeping and the sole purpose test, the stakes are rising. Australians who understand how SMSFs actually work are in a much stronger position to compare them fairly with other super options.

What Australians Should Know Before Acting

Before assuming an SMSF is the right path, Australians should consider several practical points.

First, an SMSF is a long-term legal structure. Trustees remain legally responsible even if they delegate work to accountants, administrators or advisers. The buck stops with the trustees.

Second, costs need to be assessed against the fund’s expected balance and investment style. A simple, low-cost SMSF might suit some investors with larger balances, while others may find that an industry, retail or wrap super fund is more efficient.

Third, compliance is non-Negotiable. The ATO publishes guidance on contraventions, penalties and disqualifications, and breaches can be very expensive to fix.

Finally, an SMSF affects estate planning. Trustees should think carefully about binding death benefit nominations, reversionary pensions and how the fund will be managed if a member loses capacity or dies.

For these reasons, investors should compare SMSFs with other options, read the ATO’s official trustee material and seek personal financial, legal and tax advice from licensed professionals before making any decisions.
