Self-Managed Super Fund (SMSF)
A private super fund you manage yourself, with up to 6 members, offering full control over investment choices.
A Self-Managed Super Fund (SMSF) is a private super fund that you manage yourself, regulated by the ATO (not APRA like retail and industry funds). SMSFs can have up to 6 members (increased from 4 in 2021), and all members must be trustees (or directors of the corporate trustee). This structure gives you full control over investment decisions, including the ability to invest in direct property, unlisted assets, and alternative investments not available through retail or industry funds.
SMSFs are subject to the same tax rules as other super funds — 15% tax on concessional contributions, 15% tax on investment earnings (10% on long-term capital gains), and tax-free earnings in the retirement phase. However, SMSFs come with significant responsibilities: you must develop and follow an investment strategy, keep proper records, have the fund audited annually by an approved SMSF auditor, and lodge an annual return with the ATO.
SMSFs are generally only cost-effective for larger balances — typically $200,000+ — because the fixed costs of administration, audit, and compliance are the same regardless of balance size. Running costs typically range from $2,000 to $5,000 per year. For smaller balances, a retail or industry fund is usually more appropriate. The ATO actively monitors SMSFs and can impose significant penalties for compliance breaches, including making the fund non-complying (which results in the fund's assets being taxed at 45%).
How it works
An SMSF is a private super fund where the members are also the trustees (or directors of the corporate trustee), giving direct control over investment decisions rather than relying on a retail or industry fund's investment menu. It can have up to six members and is regulated by the ATO rather than APRA. The same tax rules apply as any other fund — 15% on concessional contributions and most earnings, 10% on long-term capital gains — the difference is who makes the investment calls, not how the fund is taxed.
In practice, running an SMSF means ongoing compliance work: a documented investment strategy, an annual audit by an approved SMSF auditor, and an annual return lodged with the ATO. Because these fixed costs — typically $2,000 to $5,000 a year — apply regardless of the fund's balance, an SMSF is generally only cost-effective once the balance is around $200,000 or more; below that, the same fixed costs eat up a larger share of the balance than a retail or industry fund would charge.
The ATO actively monitors SMSFs and can impose significant penalties for compliance breaches, including making the fund non-complying, which results in the fund's assets being taxed at 45% rather than the usual concessional super rates — a severe outcome that makes ongoing compliance non-negotiable. A common misconception is that setting up an SMSF is mainly about control over investment choice; the trade-off is that same control comes with personal trustee responsibility for every compliance obligation.
Example: SMSF running costs versus balance
An SMSF with a $150,000 balance and $3,000 a year in running costs is paying about 2% of its balance in fixed admin fees alone, before any investment costs — a heavy drag compared with a typical retail or industry fund fee.
The same $3,000 fixed cost against a $400,000 balance works out to 0.75%, much closer to what a retail or industry fund might charge — which is why the ATO's rule-of-thumb $200,000-plus threshold for cost-effectiveness matters when deciding whether an SMSF makes sense.
