The 5% in-house asset limit under s.82 SIS Act isn't a one-time test — it's measured at market value every 30 June. A bear market can shrink the fund's other assets while a related-party loan or property holds its value, pushing the in-house percentage above 5% even though the trustee did nothing wrong. Rectification is required within a year, and non-compliance risks the fund losing its concessional tax treatment entirely.
Most SMSF trustees who hold related-party investments understand the 5% in-house asset rule as a one-time test at acquisition. That understanding is incomplete. Section 82 of the Superannuation Industry (Supervision) Act 1993 caps in-house assets at 5% of total fund value on an ongoing basis, measured at market value at each 30 June (ATO, https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/self-managed-super-funds-smsf/investing/in-house-assets-and-related-party-transactions/in-house-assets). The denominator moves with markets — and that is where the trap lies.
The arithmetic is simple. Imagine a retiree's SMSF holding $4,800,000 in listed shares and cash plus $200,000 in a related-party business loan. At 1 July, the in-house asset percentage is 4.0% — comfortably compliant. Then the market drops 35% across the financial year. Listed shares fall to $3,120,000. The related-party loan, being a fixed-value debt instrument from a private business, holds its $200,000 value. At 30 June: total fund value $3,320,000, in-house assets $200,000, in-house percentage 6.0% — non-compliant. The trustee has done nothing wrong. The market moved, and the rule was breached.
From the moment of identification, SIS Act s.82 requires the trustee to prepare a written plan and bring the percentage back to 5% or below by 30 June of the following financial year. The rectification options all carry real frictions. Selling the in-house asset to a non-related party at market value is the cleanest fix — but selling a private business loan or a related-party equity stake during a market downturn is exactly when buyers are scarcest. Injecting cash via member contributions grows the denominator, but the caps constrain the pace: $30,000 of concessional contributions and $120,000 of non-concessional contributions per year, or up to $360,000 under the three-year bring-forward rule subject to Total Super Balance thresholds (ATO, https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/growing-and-keeping-track-of-your-super/caps-limits-and-tax-on-super-contributions/concessional-contributions-cap). Buying more non-in-house assets requires liquidity the fund may not have. Winding down the in-house asset directly — recovering a loan, ending a lease — sometimes works, sometimes cannot.
The retirement-phase dynamic makes the problem compound. In pension phase, the fund is paying minimum drawdowns — 5% of account balance per year for a member aged 65 to 74, rising with age (ATO, https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/self-managed-super-funds-smsf/paying-smsf-benefits/minimum-annual-payments-for-super-income-streams). Those drawdowns are funded by selling liquid assets — typically the listed-share portion. As the listed-share component shrinks, the related-party investment becomes a larger fraction of the smaller remaining fund. The in-house percentage rises even without further market movement. A trustee paying $80,000 of pension out of a fund with a static $200,000 related-party investment can watch the percentage drift upward year on year.
Non-compliance consequences are severe. If the breach is not rectified by the deadline, the SMSF can be deemed non-complying. The fund loses its concessional super tax treatment and fund income is taxed at the top marginal rate — currently 45%. Trustee penalties, both administrative and pecuniary, can apply. In practice, the ATO works with trustees who are actively rectifying, but the legal threshold is strict and the consequences of inaction are catastrophic for the retirement balance.
The pre-emptive strategies follow from understanding the dynamic. Maintain a buffer well below the 5% ceiling — 2% to 3% gives room for substantial market movement before the rule bites. Hold liquid non-in-house assets that can be sold quickly if needed. Reassess whether the related-party investment belongs in the SMSF once the member moves into retirement phase — the combination of forced drawdowns and ongoing in-house testing makes the structure progressively riskier with age. For trustees holding business real property with related parties, Regulation 13.22C of the SIS Regulations carves out an exception for interests in ungeared related trusts or companies that hold business real property and meet specific structural conditions — moving the holding outside the in-house asset framework entirely.
The 5% rule is not a static check completed once at acquisition. It is a market-sensitive, ongoing test that interacts with the broader portfolio in ways most trustees do not appreciate until a downturn forces the issue. For retirees with related-party SMSF exposure, the bear-market trap is real, underappreciated, and arrives at exactly the worst time.

Key takeaways
- The 5% in-house asset limit under s.82 of the Superannuation Industry (Supervision) Act 1993 is an ongoing test, measured at market value at each 30 June, not a one-time check completed at acquisition.
- A market downturn can breach the limit on its own: if listed shares and cash fall in value while a related-party loan or business investment holds its fixed value, the in-house percentage of the smaller total fund can rise above 5% with no new investment and no trustee wrongdoing.
- Once identified, the trustee must prepare a written plan and bring the percentage back to 5% or below by 30 June of the following financial year — options include selling the in-house asset (hardest during a downturn when buyers are scarce), injecting cash via contributions (constrained by annual caps), or winding down the asset directly.
- In pension phase, compulsory minimum drawdowns are typically funded by selling liquid assets, which shrinks the non-in-house portion of the fund and can push the in-house percentage upward year on year even without further market movement.
- If a breach isn't rectified by the deadline, the SMSF can be deemed non-complying, losing its concessional tax treatment with fund income taxed at the top marginal rate (currently 45%) — pre-emptive strategies include maintaining a 2-3% buffer below the 5% ceiling and reassessing whether related-party investments still belong in the fund once the member moves into retirement phase.
Frequently asked questions
Is the SMSF 5% in-house asset rule only tested when the asset is acquired?
No. It's an ongoing test under section 82 of the Superannuation Industry (Supervision) Act 1993, measured at market value at each 30 June. A fund that was compliant at acquisition can breach the limit later purely because of market movements in its other assets, with no new related-party investment made.
How can a bear market cause an SMSF to breach the 5% in-house asset rule?
If the fund's listed shares and cash fall in value while a related-party loan or business investment holds a fixed value, the total fund value shrinks faster than the in-house asset value. The in-house asset percentage — calculated as in-house assets divided by total fund value — rises as a mechanical result, even though the trustee has done nothing to cause it.
What has to happen if my SMSF breaches the 5% in-house asset limit?
The trustee must prepare a written plan and bring the in-house asset percentage back to 5% or below by 30 June of the following financial year. Options include selling the in-house asset to a non-related party, injecting cash through contributions (limited by annual caps), buying more non-in-house assets, or winding down the in-house asset directly, such as recovering a loan.
What happens if an SMSF doesn't fix an in-house asset breach in time?
The fund can be deemed non-complying, losing its concessional superannuation tax treatment — fund income is then taxed at the top marginal rate, currently 45%. Trustee penalties, both administrative and pecuniary, can also apply, though in practice the ATO works cooperatively with trustees who are actively rectifying a breach.
