How to Lease SMSF Property to Family at Market Rent

If your self-managed super fund owns a commercial property and you want to lease it to your own business or a family member's business, the rent you charge has to match what an unrelated tenant would pay for the same premises.

That requirement sits at the centre of two separate rules. The first is the arm's length rule under the Superannuation Industry (Supervision) Act. The second is the in-house asset test. Both apply the moment a lease involves a related party, and both create problems if the rent is set below market value.

What Counts as Market Rent for an SMSF Lease

Market rent is the amount a willing tenant would pay a willing landlord for the same property in the same condition at the same time. It's not what you think is fair, or what you paid five years ago, or what the tenant can afford. It's what comparable properties in the area are leasing for right now.

For a commercial lease in Bega, that might mean checking what other shopfronts along Carp Street are charging per square metre, or what industrial sheds near the saleyards are listed at. The comparison has to account for size, location, fit-out, access, and lease terms. A short-term lease with no outgoings included will command a different rent to a five-year lease where the tenant covers all costs.

If the property is unique or there are few comparables, you'll need a formal valuation from a qualified property valuer with local knowledge. The valuation should be updated regularly, particularly when market conditions shift or the lease is renewed. A valuation from three years ago won't satisfy the requirement if rents have moved since then.

Why the ATO Treats Below-Market Rent as Non-Arm's Length Income

When an SMSF leases property to a related party at below-market rent, the ATO can treat the shortfall as non-arm's length income. That income is taxed at 45 percent, not the usual 15 percent rate that applies to super fund earnings.

Consider a scenario where your SMSF owns a workshop in Bega and leases it to your landscaping business for $1,200 per month. If comparable properties are leasing for $2,000 per month, the ATO may assess the difference of $800 per month as non-arm's length income. Over a year, that's $9,600 taxed at 45 percent instead of 15 percent. The additional tax bill would be $2,880, which comes directly out of the fund's balance and reduces what's available for your retirement.

The non-arm's length income rules were strengthened in recent years and now apply more broadly than before. The ATO's position is that any arrangement that results in the fund receiving less income than it would in an arm's length dealing can trigger the higher tax rate. That includes rent set too low, rent reviews that aren't conducted, or lease terms that favour the tenant beyond what a commercial landlord would accept.

How the In-House Asset Test Applies to Related Party Leases

Business real property leased to a related party is excluded from the in-house asset rules, but only if the lease is made on arm's length terms. If the rent is below market value, the property may be treated as an in-house asset. An SMSF cannot hold more than five percent of its total assets as in-house assets. If the fund breaches that limit, it loses its complying status and faces penalty tax.

Business real property means land and buildings used wholly and exclusively in one or more businesses. The property must be used for business purposes at all times, not just most of the time. A property with a residential component, such as a shop with a flat above it, may not qualify unless the residential portion is clearly separated and not used.

The definition is strict. A property marketed as commercial doesn't automatically meet the test if the actual use is mixed or domestic. The ATO looks at how the property is being used, not what it's zoned for or how it's described in the listing.

Setting Rent When the Lease Starts and Reviewing It Over Time

Rent should be set at market value when the lease is signed and reviewed at every rent review date specified in the lease. Most commercial leases include annual or biennial rent reviews, either as a fixed percentage increase or a market review. If the lease specifies a market review, that review must actually take place.

In Bega, commercial rents can shift depending on local demand, particularly in sectors tied to agriculture, tourism, or government services. A retail premises on Auckland Street might hold value differently to a warehouse on the Tathra side of town. Rent set in one year may no longer reflect market conditions two or three years later, especially if nearby businesses have closed or new developments have changed the area's appeal.

Where the lease includes a CPI-based increase, check whether that increase still results in market rent. CPI adjustments don't always track actual rental movements. If market rents have risen faster than CPI, the lease may fall below market value even with annual indexation.

What Happens If You Get the Rent Wrong

If the ATO identifies that an SMSF has been leasing property to a related party at below-market rent, the consequences depend on how long the issue has been occurring and whether it was deliberate. The fund may face additional tax on non-arm's length income, penalties for breaching the in-house asset rules, and potential loss of complying status.

Loss of complying status means the fund is taxed at the top marginal rate on all its income, not just the rental income. That can wipe out years of contributions and earnings in a single financial year. Even if the breach is corrected, the fund may still face administrative penalties and will need to demonstrate to the ATO that it has systems in place to prevent future breaches.

Trustees are also personally liable for breaches of the superannuation rules. If the fund cannot pay the penalty, the ATO can pursue the trustees personally. That's particularly relevant where the fund's assets are tied up in property and there's limited cash to cover unexpected liabilities.

When to Get a Valuation and When to Use Comparable Evidence

A formal valuation from a registered valuer is the safest approach, particularly when the lease is first signed or when there are few comparable properties. Valuations should be updated every two to three years, or sooner if there's been a significant change in the local market.

For properties where there are clear comparables, such as a standard retail or office space in a well-serviced area, you may be able to support the rent with evidence of similar leases in the area. That evidence should be documented and kept with the fund's records. Screenshots of listings, leasing agent reports, or local market summaries from a real estate agency can all support the rent figure, but they need to be current and directly relevant to the property type and location.

Where the property has been modified or improved, the valuation needs to account for that. A shed with a cool room installed is not comparable to a bare shed. A shopfront with a commercial kitchen fitted out is not the same as an empty retail space. The rent charged should reflect the actual state of the property as leased.

If you're working with a mortgage broker or SMSF advisor in the region, they'll often have contacts with local valuers and leasing agents who understand the Bega commercial property market. That local knowledge matters when comparables are scarce or when the property type is specific to the area, such as farm sheds, cool stores, or timber mill facilities.

Using Super to Buy Commercial Property Through an SMSF Loan

If your SMSF is buying the commercial property with borrowed funds under a limited recourse borrowing arrangement, the loan terms also need to meet arm's length conditions. The ATO publishes safe harbour interest rates each year. If the loan is from a related party and the interest rate is below the safe harbour rate, the income from the property may be treated as non-arm's length income.

The interest rate for related party loans secured by commercial property is typically higher than the residential rate. For the current year, check the ATO's published guideline or speak to an SMSF specialist before setting the loan terms. The loan must also be limited in recourse to the property being purchased, meaning the lender can only claim against that asset if the loan defaults, not against other fund assets.

If you're considering refinancing an existing SMSF loan or setting up a new loan to acquire commercial property, the same market rent rules apply once the property is leased to a related party. The rental income needs to service the loan, cover holding costs, and still reflect what an independent tenant would pay.
