Commercial Lease to Related Party: 5 Critical Rules

When an SMSF owns property and contemplates entering into a commercial lease with a related party, the arrangement must be carefully structured. A commercial lease between the fund and a related party can offer great benefits such as stable rental income, asset control, and member business integration—but it also carries significant regulatory risks.
Trustees must understand the rules around a commercial lease with a related party, ensure compliance with the in‑house asset rules, confirm arm’s‑length terms and document the arrangement properly. At WA SMSF Specialists, led by Bradley Raw CA SSA, trustees receive guidance on structuring a commercial lease to a related party correctly and safely.

In this article we set out five critical rules trustees must observe when setting up a commercial lease to a related party, illustrate key concepts, and provide practical best‑practice steps. Throughout we reference both “commercial lease” and “related party” frequently, as both terms are central to the arrangement.

Rule 1: Ensure the Property Qualifies as Business Real Property and the Lease is on Arm’s‑Length Terms

One of the first essential requirements before executing a commercial lease with a related party is to ensure the property is business real property (BRP). If the SMSF is leasing its property to a related party via a commercial lease, the property must satisfy the definition of business real property to avoid contravening the in‑house asset rule.

A related party leasing a property from the SMSF under a commercial lease must be treated no differently with respect to commercial terms than an unrelated third‑party tenant. The lease must reflect market rental rate, appropriate term, responsibilities for maintenance, and regular review in the same way as a non‑related tenant. dbalawyers.com.au

Key actions:

• Obtain a third‑party market rental valuation before the commercial lease to the related party is entered.
• Document the commercial lease, specifying the term, rental payment frequency, expense responsibilities (rates, insurance, repairs), review mechanisms.
• Ensure the property remains business real property, and no personal use is made by the related party outside the business purposes.
• Review the lease annually (or as required) to compare with market rates and adjust accordingly.

If a commercial lease to a related party fails to comply with arm’s‑length terms or the property does not qualify as BRP, the SMSF may breach the in‑house asset rules or fail the sole‑purpose test, putting tax concessions at risk.

Rule 2: Avoid Leasing Residential Property to a Related Party Unless Strict Conditions Are Met

While an SMSF may engage in a commercial lease to a related party if the property is business real property, leasing residential property to a related party is far more restricted. The rules are strict because residential leases to a related party may be caught as an in‑house asset and/or breach the sole purpose test.

For instance, a lease of residential property by an SMSF to a related party member is generally prohibited unless the value of the in‑house assets (which may include the lease arrangement) remains under 5% of the total fund assets.

Therefore, if the property is residential and the SMSF proposes a commercial lease to a related party, trustees must treat the arrangement as higher risk and ensure that the property is genuinely commercial in nature, or doesn’t involve the related party living in the property (unless strict exemptions apply). The arrangement should focus on business use rather than personal residential use.

Rule 3: Document the Commercial Lease to a Related Party Clearly and Conduct Regular Reviews

Proper documentation is fundamental when entering a commercial lease with a related party. As many guidance sources highlight: a commercial lease to a related party must mirror third‑party leases in almost all respects.

Key elements of the lease should include:

• Start date, term, and options for renewal.
• Rent amount, payment frequency (e.g., monthly), and any review/increase clause.
• Which party pays for property expenses (rates, insurance, maintenance, repair).
• Make‑good or restoration clauses, retention of ownership of tenant fit‑out where relevant (especially in a commercial lease scenario). dbalawyers.com.au
• Regular market‑rent reviews, with third‑party evidence.
• Lease must be signed before the related party moves in or starts using the premises.

Once a commercial lease is in place, trustees should annually review the lease against market conditions and document any variations. Failure to do so may expose the SMSF to audit risk or contravention of related‑party rules.

Rule 4: Ensure the Financial Benefits, Risks and Terms of the Commercial Lease to a Related Party Align with the SMSF’s Strategy

A commercial lease to a related party must align with the SMSF’s investment strategy and risk profile. If the SMSF owns property and leases it to a related party, trustees must consider how this commercial lease fits into liquidity, risk, diversification, and retirement objectives. Failure to incorporate the commercial lease to a related party into the SMSF investment strategy may breach trustee duties.

Considerations include:

• Cash‑flow: Will the rent from the related party under the commercial lease cover property costs, insurance, maintenance and SMSF outgoings?
• Concentration risk: If the commercial lease income depends entirely on one related party tenant, the SMSF may lack diversification.
• Exit strategy: Assess what happens if the related party tenant defaults or vacates — can another tenant be found on a commercial lease basis?
• Governance: The commercial lease must be managed carefully to avoid the related party effectively controlling the fund asset without proper oversight.

Trustees should document how the commercial lease to a related party contributes to their SMSF’s goals and ensure that it remains consistent as member circumstances evolve.

Rule 5: Monitor Compliance Risks, Especially the In‑House Asset Rule and Sole Purpose Test Related to Commercial Lease and Related Party Arrangements

Whenever an SMSF enters a commercial lease with a related party, compliance risks are elevated. Two major risks to focus on: the in‑house asset rule and the sole purpose test.

In‑House Asset Rule

Leasing property to a related party may trigger the in‑house asset limits if the lease is treated as an in‑house asset rather than legitimate business real property. The in‑house asset rules generally cap in‑house assets at 5% of the SMSF’s total assets.

To mitigate this risk when a commercial lease to a related party is in place:

• Confirm the property is business real property (BRP).
• Document the commercial lease on arm’s‑length terms.
• Ensure the related party is a business tenant and the property is used wholly and exclusively in that business.
• Maintain evidence that the lease to the related party meets market terms and that property use remains commercial.

Sole Purpose Test

The SMSF must be maintained solely for the purpose of providing retirement benefits to its members, or their dependants after death. If a commercial lease to a related party undermines this—e.g., by providing private benefit to a member—then the arrangement may breach super laws. The ATO will examine whether the lease is genuinely arm’s‑length and whether the related party receives any non‑commercial benefit.

Other Compliance Issues

• Related‑party improvements via the tenant could be treated as contributions if not managed carefully. dbalawyers.com.au
• Lease terms must avoid giving the related party control of the SMSF asset beyond standard tenancy rights.
• Trustees must keep robust records including the commercial lease document, market rent evidence, payment receipts, and audits of the arrangement.

Regular monitoring ensures that the commercial lease arrangement with a related party remains compliant and doesn’t inadvertently convert into an in‑house asset or give prohibited private benefit.

Conclusion

A commercial lease to a related party can be a viable strategy for SMSFs that own business real property, but only if structured carefully and compliant with all regulatory requirements. The five critical rules outlined above provide trustees with a guide to minimise risk and maximise benefit:

1. Ensure the property qualifies as business real property and lease terms are arm’s‑length.
2. Avoid leasing residential property to a related party unless strict conditions apply.
3. Document the commercial lease with a related party clearly and conduct regular reviews.
4. Ensure the commercial lease to a related party aligns with the SMSF’s investment strategy, liquidity and risk profile.
5. Monitor key compliance risks including the in‑house asset rule, sole purpose test, and contributions via tenant improvements.

By following these rules, SMSF trustees can structure a commercial lease with a related party that delivers value, remains aligned with the fund’s retirement goals, and avoids regulatory pitfalls. Experts such as Bradley Raw, CA SSA at WA SMSF Specialists are well placed to assist in setting up and reviewing these arrangements to ensure compliance, documentation and strategic alignment.

Frequently Asked Questions

1. Can an SMSF enter into a commercial lease with a related party?
Yes—an SMSF can enter into a commercial lease with a related party if the property is business real property, the lease is arm’s‑length, and the arrangement meets compliance requirements including the in‑house asset rule and sole purpose test.

2. What does arm’s‑length terms mean in a commercial lease to a related party?
Arm’s‑length terms mean the lease conditions (rent amount, term, tenant obligations, review mechanisms) are the same as would apply if the tenant were unrelated. For a commercial lease to a related party, trustees should obtain third‑party rental valuations and document the lease accordingly.

3. Why is leasing residential property to a related party more risky than a commercial lease?
Residential leases to a related party often do not qualify as business real property and may be treated as in‑house assets, which increases compliance risk. The property may also fail the sole purpose test if a member uses the property personally.

4. What records should an SMSF keep for a commercial lease to a related party?
Records should include the written lease document, market rental evidence, proof of rent payments made on time, evidence of expense responsibilities, annual reviews of the lease terms, and how the arrangement aligns with the SMSF investment strategy.

5. Could improvements made by a related party tenant in a commercial lease become a problem?
Yes. If a related party tenant pays for a floor plan fit‑out or other significant improvements without proper retention of ownership or make‑good clauses, the improvement might be treated as a contribution or trigger non‑compliance. Trustees should include appropriate clauses to avoid this risk.

6. How does the in‑house asset rule affect a commercial lease to a related party?
If a commercial lease to a related party does not qualify as business real property, the lease may be treated as an in‑house asset, which must not exceed 5% of the SMSF’s assets. Exceeding that limit triggers breaches of super law.

7. What happens if the SMSF breaches the sole purpose test because of a commercial lease to a related party?
If the arrangement serves a private benefit (for example, favourable lease terms to the related party or personal use of the property by a member), the SMSF may be non‑complying and lose tax concessions, and trustees may face penalties.

8. How often should a commercial lease to a related party be reviewed?
Annually or whenever market conditions change. The lease should be reviewed to ensure rent remains at market rate, the tenant obligations remain appropriate, and the arrangement still aligns with the SMSF’s strategy.

9. Can a commercial lease to a related party be backdated or informal?
No. The commercial lease to a related party must be properly executed in writing before use, must reflect market terms, and must be formally documented. Informal or backdated leases increase compliance risk.

10. Should I seek professional advice before entering a commercial lease to a related party?
Yes. Because the combination of a commercial lease and a related party introduces complexity around valuation, compliance, documentation and strategy, using specialist advice from firms like WA SMSF Specialists ensures you structure the lease correctly and maintain ongoing compliance.
