Auditing In-House Assets: Rules, Risks, and Compliance Tips

Swarn Sandhu | 06-Jan-2026

What Counts as In-House Assets?

In-house assets are one of the most commonly misunderstood areas of SMSF compliance. The ATO regularly reports that thousands of SMSFs breach the rules each year simply because trustees don’t fully understand what an in-house asset is or how the 5% limit works.

An in-house asset is any investment your SMSF makes with a related party, whether it’s a loan, an investment in a related company, or certain types of assets leased to related parties. This is because these transactions can easily create conflicts of interest. In addition, the ATO monitors them very closely. As a result, auditors play a key role in checking whether SMSFs stay within the legal limits.

The 5% Rule Explained

The 5% rule is the cornerstone of the in-house asset rules. It means your SMSF can only have in-house assets up to 5% of the fund’s total assets at market value. This percentage is tested every financial year on 30 June.

How the 5% Rule Works in Simple Terms

If your SMSF has $800,000 total assets, you can only have up to $40,000 in in-house assets. If the market value goes above 5% on 30 June, whether due to investment performance or a change in valuations, you must prepare and execute a written plan to reduce the in-house assets to the allowed limit within 12 months.

What counts as an in-house asset?

  • Loans to members or relatives
  • Loans to related trusts or companies
  • Investments in related companies or unit trusts
  • Assets leased to related parties (with limited exceptions)

What does not count?

  • Business real property leased to a related party (allowed if rules are met)
  • Cash held in bank accounts
  • Listed shares in unrelated companies
  • Managed funds or ETFs

Even though some related-party transactions are allowed, they must meet strict conditions. Auditors are required to check every detail.

What are the Risks of Breaches?

In-house asset breaches happen more often than most trustees realise. Many occur unintentionally, such as when a related trust suddenly drops in value and pushes the SMSF over the 5% limit. But even accidental breaches can trigger consequences.

Some of the common risks and consequences are listed below:

Financial penalties – The ATO may impose administrative penalties on trustees personally, not from SMSF funds.
Forced asset disposal – If the SMSF exceeds the 5% cap, trustees must create a written plan to fix the breach within 12 months. If they do not act, the ATO can force the sale of assets.

Compliance status at risk – Repeated or large breaches can result in the fund being made non-compliant, which may lead to higher tax rates (up to 45% on fund assets).

Lending to members (illegal) – Loans to members or relatives are one of the most serious breaches. The ATO flags hundreds of cases each year where SMSFs provided “temporary loans” to cover personal bills or business expenses. These are strictly prohibited.

Unapproved related-party transactions – Investments in related companies often breach rules when the loans aren’t properly documented, or no commercial terms exist. It can also occur if interest is not charged or security is missing.

Property leased to related parties – If the property is not business real property, leasing it to a related party becomes an in-house asset and may exceed the 5% limit.

The ATO’s annual reports show that in-house asset breaches remain one of the top five compliance issues for SMSFs. As a result, auditors must apply strong oversight.

Audit Compliance Approach

When auditing in-house assets, the auditor’s main job is to check whether your SMSF has stayed within the 5% limit and whether all related-party dealings follow the strict ATO rules. Auditors begin by reviewing your fund’s financial statements to confirm the market value of all assets as of 30 June. This helps them determine the exact percentage of in-house assets for the year.

Next, the auditor examines documents related to loans, related-party trusts, related companies, and any property leased to related parties. They look for proper agreements, valuations, repayment terms, and evidence that transactions were made on normal commercial conditions. Even a small mistake, such as a missing loan agreement or an incorrect valuation, can lead to a compliance issue.

If your in-house assets exceed 5%, the auditor must verify that you have created a written rectification plan and that it is realistic and prepared within the required timeframe. They also review whether the trustee has started taking steps to bring the fund back under the limit. Overall, an SMSF auditor ensures that your fund is protecting member money and following ATO rules without any hidden risks.
