SMSF investment rules: What every trustee should know

Self-managed super funds (SMSFs) can potentially provide members with far more control and flexibility than big super funds, but that doesn’t mean it’s open slather. Breaking the rules can be costly.

The Australian Taxation Office (ATO) has the power to issue financial penalties on SMSF trustees who break the investment rules or fail to meet their tax obligations.

These penalties are referred to as the trustee penalty provisions.

Penalties are assigned ‘penalty units’ ranging from five to sixty. Currently, each penalty unit incurs a fine of $330. So, a breach of five penalty units would mean a penalty of $1,650 and a breach of sixty units would mean a penalty of $19,800.

It is, therefore, important that SMSF members have a clear understanding of the rules and their responsibilities when it comes to overseeing their SMSF.

Need to know

All trustees must sign a trustee declaration – a legal document that signifies they have understood all their legal requirements as a trustee.

The trustee declaration must be read and signed by anyone looking to join an SMSF and it must be kept on file.

Learn more about the SMSF trustee declaration.

SMSFs also need a trust deed that sets out how the fund will be run and operated. Trust deeds are usually sourced from a legal (document) provider and they can differ, depending on their source.

So, it’s important you understand the wording and rules contained within your own SMSF trust deed.

SMSF trustees must also develop and implement a fund-specific investment strategy that explains how they believe the investments chosen are in the best interests of members.

Sole purpose test

SMSFs need to comply with the sole purpose test, which requires your super fund to be run for the sole purpose of providing retirement benefits for its members.

The sole purpose test applies to all super funds, not just SMSFs. You can read more about how it relates to SMSFs in ‘Self-managed superannuation funds ruling SMSFR 2008/2: sole purpose test’.

The sole purpose test prohibits trustees from maintaining an SMSF for purposes other than for providing retirement or death benefits for, or in relation to, SMSF members. These are referred to as the core purposes.

In addition, the SMSF can also be maintained for other specified ancillary purposes relating to the provision of benefits on the cessation of a member’s employment and other death benefits and approved benefits not specified under the core purpose.

Essentially if you, or anyone related to the fund, receives a financial benefit not related to your retirement, then your fund might not meet the sole purpose test.

Assets in the name of the fund

It’s a legal requirement that your SMSF holds investments in the name of the trustee(s) of the fund – not in your own name. For example:

  • ABC Pty Ltd as trustee for the XYZ Superannuation fund
  • Mr. A Jones and Mrs. B Jones as trustees for the Jones Superfund.

Your SMSF must have its own bank account and again, this needs to be held in the correct name.

As the assets belong to the fund trustee, they are somewhat protected in the event of a personal legal dispute against one of the members’ assets.

The penalty for failing to keep the assets of the fund separate from members’ personal assets is 20 penalty units, where each penalty unit is $330 (as at March 2026) and applies to each trustee, which would be $6,600 for each individual trustee of the fund or $6,600 in total for a corporate trustee.

Investing in the name of the fund is relatively straightforward for most kinds of assets. However, if your fund invests in property and the property is not owned outright by the fund, you must be careful about which legal entity is the holder of the asset. This is particularly the case if your fund acquires the asset via a limited recourse borrowing arrangement (LRBA).

In these cases, a holding trust will need to be set up to acquire the asset, and it is the holding trust that needs to be on the contract. However, this will depend on the state in which the asset is located, so it’s important to get legal advice on the issue.

Learn more about LRBA structures.

Where there is a legal impediment in holding SMSF assets in the correct name, the fund trustees can put in place acknowledgements or declarations that the asset is being held on behalf of the SMSF. As there are separate legal and tax issues that need to be considered, which often differ between jurisdictions, states and territories, it is best to seek legal advice on this.

Restrictions (on investments)

An SMSF isn’t a free-for-all when it comes to investments. There are restrictions around what you can and can’t invest in that have evolved over time as the regulator cracks down on loopholes.

In addition to possible penalties for breaching the rules, if you don’t abide by these restrictions, your SMSF may lose its concessional tax treatment, which would increase its tax rate from 15% to the highest marginal tax rate of 45%. A trustee can also be disqualified.

Collectables

The regulations for investing in collectables have tightened over the years and now state that collectables or personal use assets cannot be stored in the private residence of any related party of the fund.

Items must also be insured in the fund’s (trustee’s) name within seven days of acquisition and must be allowed in the fund’s trust deed and explained in the fund’s investment strategy.

Learn more about investing in collectables.

Borrowing

Rules around borrowing to buy assets, such as property, have evolved over time. Where originally it was barely allowed at all, a relaxation of these rules in 2007 means that, in very specific circumstances, SMSFs can purchase properties, and occasionally other assets, through limited recourse borrowing arrangements (LRBA) or through instalment warrants. Both these types of borrowings limit the lender’s rights to the asset and the lender cannot claim on other assets held in the SMSF.

Also, in limited circumstances, your SMSF can borrow money for a short period if the amount is less than 10% of the fund’s total assets. Those circumstances are:

  • A maximum of 90 days to meet benefit payments or to pay an outstanding surcharge liability, or
  • A maximum of seven days to cover the settlement of security transactions. You can only do this if, at the time you bought the securities, you did not think you would need to borrow funds.

Learn more about borrowing to invest.

All investments by your SMSF need to be made on a ‘commercial arm’s-length basis’. If you invest in an asset, you need to get a market rate of return for it. If you buy (or sell) an asset that needs to be at market value as well. If it isn’t, you will breach the arm’s-length requirements.

When it comes to complying with the arm’s-length requirement, one of the biggest challenges for SMSF trustees is the rules about related parties and investments.

A related party is not just a relative or another member of your SMSF – it includes associates of all members of the SMSF. This is defined by the ATO as:

  • The relatives of each member
  • The business partners of each member
  • Any spouse or child of those business partners
  • Any company that the member, or their associates, control or influence
  • Any trust that the member or their associates control.

‘Business partners’ refers to the situation where the member, or a relative, is a partner in a partnership and other partners in the partnership are included as related parties.

Important

It is the tax law definition of a partnership that is used for the related party test, and this definition is much wider than just two or more people carrying on a business together.

For instance, a property owned jointly by two or more individuals would result in those individuals being in receipt of income jointly and hence be in a partnership for tax law purposes. The same could apply where a bank account earning interest is owned by two or more individuals.

Problems arise when related parties, say a son or business associate, sell an asset to an SMSF at below market value. That would be in breach of the arm’s-length rule.

Read more about the arm’s-length rule.

Need to know

Income earned through the SMSF by activities conducted on a non-arm’s-length basis is called non-arm’s-length income (NALI) and is taxed at the highest marginal rate.

In-house assets

Assets that have connections to related parties are called in-house assets and include:

  • An investment in a related trust of your fund
  • A fund asset that is leased to a related party
  • An investment in (or a loan to) a related party of your fund.

Learn more about in-house assets.

The total of all in-house assets cannot exceed 5% of your SMSF’s total assets at market value. Exceptions to this rule include business real property or commercial property.

A related company (as opposed to the property the business operated in) would not be an exception to the in-house asset test. So, the SMSF could only invest 5% of the fund’s assets in the related company. The investment would also have to be at market value in accordance with the arm’s-length rule.

Need to do

The ATO suggests SMSF trustees make a list of all related parties of the fund when the fund is established and check investment restrictions if the fund ever contemplates transacting with any of the parties on the list.

Lending money and early access

Under Section 65 of the Superannuation Industry (Supervision) Act 1993, SMSF trustees are not able to lend money or give any other financial assistance using the resources of the fund to a member of the fund or a relative of a member of the fund.

This is a separate restriction to the in-house assets test and means that no amount from a super fund can be lent to a member of the fund or their relatives.

Withdrawing funds from the SMSF to give to a relative of a member would fall under ‘other financial assistance’ and could, in most cases, be regarded as early access to super. Early access is illegal if the member has not met a condition of release that allows the trustees to pay the benefit.

Letting a family member stay in a property owned by an SMSF rent-free would also be considered financial assistance and not allowed. These arrangements would also breach a number of other strict investment rules!

There are some limited instances when an SMSF can lend to a related party, providing it is not a member or their relative, as long as it does not breach the in-house assets test. The loan needs to be on an arm’s-length basis and the SMSF’s investment strategy would also need to explain how the loan is in the members’ best interests.

Exotic investments such as foreign currencies, commodities, options and cryptocurrency

Foreign currencies and commodities are usually traded via contracts for difference or CFDs.

SMSFs can invest in CFDs, but they should be careful when depositing funds with the CFD provider. They can deposit funds when they open their account, but they should not, under a separate written agreement with the provider, deposit fund assets as security for margin calls on the investment. That would create a charge over the fund assets, which is not allowed.

An SMSF’s investment strategy and trust deed need to allow CFDs and explain how investing in CFDs benefits the fund. Also, a risk assessment statement – called a derivatives risk statement – needs to be part of the investment strategy.

CFDs are a complex leveraged instrument, and any risk assessment statement should include an explanation of the trustee’s level of knowledge and experience with the asset class.

Investments in options and cryptocurrency are also allowed, provided the trust deed allows it, and the investment strategy explains the motivation and includes a risk assessment statement.

For tax purposes, cryptocurrencies are not a form of money but are capital gains tax assets.

Carrying on a business within an SMSF

Your SMSF can invest in a business if you can show it’s being run for the sole purpose of retirement savings, is conducted on an arm’s-length basis and is allowed under the trust deed. The investment strategy must explain why and how the investment is in the members’ best interests.

The ATO has cited the following as the kinds of cases that attract their attention when it comes to businesses conducted by the trustees of SMSFs:

  • The trustee employs a family member (we look at things such as the stated rationale for employing the family member and the salary or wages paid)
  • The ‘business’ is an activity commonly carried out as a hobby or pastime
  • The business carried out by the fund has links to associated trading entities
  • There are indications that the fund’s business assets are available for the private use and benefit of the trustee or related parties.

Need to know

The ATO also points out that:

The rules governing SMSFs prohibit or limit some activities available to other businesses, such as entering into credit arrangements or having overdrafts. You should get professional advice before carrying on a business through your SMSF.

The bottom line

There are many investment options available to SMSF trustees, but whatever you choose to invest in, you need to stick to the rules. You must also explain in your investment strategy how each investment is in the SMSF members’ best retirement interests.
