SMSF Investment in Private Companies: Understanding the Rules

Self-managed super funds (SMSF) offer flexibility and control, especially when it comes to investment choices. But if you’re considering investing your SMSF in a private company, act carefully — it’s not as simple as buying a few shares. From ATO regulations to complex valuation requirements, there are critical rules every SMSF trustee needs to understand.

In this blog, our smsf accountants will break down the rules, risks, and realities of SMSF investment in private companies, so you can make informed decisions and stay compliant.

Why Invest in a Private Company Through an SMSF?

For some SMSF trustees, investing in private companies is appealing due to the potential for higher returns, early-stage investment opportunities, and strategic alignment with existing portfolios. However, private company investments are subject to more scrutiny than investing in listed shares.

You must ensure:

• The investment is for the sole purpose of providing retirement benefits.
• The company is not a related party; if it is, it falls within strict limits.
• You can justify the annual market valuation of the investment.
• You meet in-house asset rules.

What Are the SMSF Investment Rules?

The Australian Taxation Office (ATO) has clear rules around SMSF investment in private companies:

🔹 1. The Sole Purpose Test

The investment must genuinely aim to provide retirement benefits. It cannot exist to support a business you’re involved in personally, help a family friend, or generate early access to benefits. Any deviation from this can breach the sole purpose test — a serious compliance offence.

🔹 2. Related Party Restrictions & In-House Asset Rule

If the private company is controlled by you or a related party (e.g. a family member or business associate), the investment may be classified as an in-house asset. SMSF’s are only allowed to have a maximum of 5% of their total assets in in-house assets.

Going over this limit requires a written plan to bring it back under control, or the fund risks being made non-compliant.

🔹 3. Arm’s Length Requirements

All transactions must occur on commercial terms. Suppose your SMSF buys shares in a private company at below-market value, or the company pays above-market dividends. In that case, the income may be considered non-arm’s length income (NALI) and taxed at the highest marginal rate (up to 45%).

What Needs to Be in Place?

To even consider this type of investment, SMSF trustees must ensure:

• The trust deed allows for such investments
• The investment strategy reflects this kind of asset.
• There’s a clear and defensible valuation method.
  
• Access to company financials is guaranteed for auditing.

For example, if your SMSF invests in a start-up with limited trading history and no independent valuation, you may struggle to prove market value each year, placing your compliance at risk.

Risks of Investing in Private Companies Through an SMSF

It’s not just about the rules — there are real risks involved:

• Liquidity issues – You may not be able to exit the investment easily if cash is needed for pensions or lump sum payments.
• Limited valuation transparency – Private companies aren’t listed, so it can be difficult to provide independent valuations.
• Concentration risk – Relying too heavily on a single private company can reduce diversification, a requirement under your investment strategy.
• Compliance risk – Failing any one of the rules above could see your fund penalised or lose its complying status.

A Case for Professional Support

Because the rules are complex and the stakes are high, this is where an SMSF accountant becomes indispensable. At Bruce Edmunds, we help Melbourne trustees assess:

• Whether a proposed investment meets the SIS Act
  
• If the 5% in-house asset cap will be breached
• How to structure the investment in line with your trust deed
  
• What ongoing reporting and valuation will be required?
  

For investors wanting to be proactive but cautious, we also help with strategy reviews and adjusting the portfolio to stay compliant over time.
