Avoid These SMSF Related Party Lease Mistakes

Market Rent is Not Optional

Any lease between your SMSF and a related party must be made on arm's length terms at market value. This requirement sits in section 109 of the SIS Act and applies whether the related party is your company, partnership, trust, or any other entity you control. The Australian Taxation Office treats non-compliance as a breach of the sole purpose test and the in-house asset provisions, even though business real property is otherwise excluded from in-house asset restrictions.

A market valuation performed by a qualified property valuer is the only acceptable method to determine annual rent. A desktop estimate or comparison to advertised listings will not satisfy the requirement if the ATO or fund auditor requests documentation. The valuation must consider the specific use, lease terms, location, and condition of the property at the time the lease is entered into. Many fund trustees assume a market range is acceptable, but the lease must specify a single dollar figure that sits within that range and is supported by the valuation report.

How Market Rent is Determined

Market rent reflects the amount a willing but not anxious tenant would pay a willing but not anxious landlord for the same property under comparable lease conditions. The valuer assesses recent leasing transactions for similar commercial properties in the same precinct, adjusts for differences in size, fit-out, and lease structure, and provides a dollar-per-square-metre rate or total annual figure.

Consider a Self-Managed Super Fund that acquires a warehouse in Welshpool through an SMSF commercial loan. The property is 400 square metres and will be leased back to the member's logistics company. The valuer identifies three comparable transactions within two kilometres: $180 per square metre, $195 per square metre, and $170 per square metre. After adjusting for age, access, and roller door configuration, the valuer concludes that $185 per square metre is appropriate, producing an annual rent of $74,000 plus GST. The lease must reflect this figure or sit within the range the valuer considers defensible. Picking the bottom of the range without justification exposes the trustee to compliance risk.

Lease Terms That Trigger Scrutiny

Rent-free periods, delayed payment terms, and contingent rent clauses are rarely arm's length in related party leases unless the valuer explicitly accounts for them in the market rent assessment. A lease that defers the first rent payment for six months without a corresponding reduction in the headline rent figure will be treated as non-arm's length. If market conditions support an incentive, the valuer must quantify it and the lease must document it clearly.

Options to renew at a predetermined rent, or leases that allow the tenant to set rent based on financial performance, do not meet the arm's length standard. Rent must be reviewed at intervals that reflect commercial practice in the relevant property sector. For most commercial leases in Western Australia, this means annual reviews tied to CPI or fixed percentage increases, with a market review at each option period. A lease that locks in the same dollar figure for five years without review will not withstand auditor or ATO scrutiny, even if the initial rent was at market.

Valuation Timing and Frequency

The initial market valuation must be obtained before the lease is signed. Retrospective valuations are not acceptable. Where the lease includes annual CPI increases, a new valuation is not required each year, provided the CPI adjustment clause is standard and the initial rent was set correctly. A full market review is required at each option renewal or if the lease terms change materially.

A fund trustee who renews a lease after three years without obtaining a current valuation risks setting rent below market if property values or demand have increased. In growth precincts such as Jandakot or around the Kewdale industrial corridor, rental rates can shift materially over a short period. The auditor will compare the lease rate to recent transactions and, if a gap exists, may qualify the fund's financial statements or issue a contravention report.

What Happens When Rent is Below Market

If the ATO determines that rent is below market, the shortfall is treated as non-arm's-deal income under section 295-550 of the Income Tax Assessment Act 1997, taxed at 45% rather than the concessional 15% rate. The trustee may also face administrative penalties under section 166 of the SIS Act for failing to maintain arm's length dealings. The fund auditor is required to report contraventions to the ATO, which can result in enforcement action including rectification directions, education directions, or disqualification of the trustee.

The tenant does not receive a corresponding deduction for the below-market component. The rent paid is deductible as normal, but the fund's tax position is compromised and the compliance breach remains on the fund's record. Rectifying the issue requires bringing the rent to market immediately, obtaining a compliant valuation, and amending the lease. The ATO does not accept gradual increases over multiple years as a remedy.

Lease Documentation and Audit Requirements

The lease must be a written agreement executed before occupation begins. Verbal agreements, informal arrangements, and backdated leases do not satisfy the requirements under either the SIS Act or the fund's limited recourse borrowing arrangement. The lender's security documentation will typically require the lease to be registered if the term exceeds three years, and a failure to register can breach both the loan terms and the trustee's obligations.

The fund auditor will request the lease agreement, market valuation, and evidence of rent receipts. Payment must occur on the due date specified in the lease. Late payments or irregular payment patterns raise red flags. If the tenant is experiencing cash flow difficulties, the lease cannot be informally varied or paused. Any concession must be documented in a formal lease variation and assessed against the arm's length standard at the time the variation is made.

GST and Rental Income Treatment

Commercial property leases are generally subject to GST, and the fund must be registered for GST if the annual rent exceeds $75,000. Rent is treated as assessable income and taxed at 15% in accumulation phase or 0% if the fund is in pension phase, provided the lease is compliant. Capital gains tax applies when the property is sold, with a one-third discount available if the property is held for more than 12 months and certain conditions are met.

The tenant can claim GST credits on the rent paid, provided the fund issues a tax invoice. The fund's GST liability on rental income and any capital gain is separate from the tenant's tax position and does not create circularity. The rental income contributes to the fund's earnings, which are used to service the limited recourse borrowing arrangement and meet the fund's investment objectives.

Refinancing and Market Rent Reassessment

When a fund refinances an existing SMSF commercial loan, the lender will review the lease to confirm rental income supports serviceability. If the lease has not been reviewed for several years and the rent is below current market, the lender may require a new valuation and lease variation as a condition of approval. This is common when refinancing to access equity or when moving from a fixed to variable rate structure.

Fund trustees who plan to refinance their SMSF loan should obtain a current market valuation at least 90 days before lodging the application. Lenders assess net rental income after deducting outgoings, vacancies, and management costs. A lease that is close to expiry or includes below-market rent will reduce the amount the lender is willing to advance, even if the property value has increased.
