Business real property and SMSFs: what your fund can actually borrow to buy

Short answer. Business real property is land used wholly and exclusively in one or more businesses. Since 10 August 2026 it is the only real property an Australian SMSF can borrow to acquire. The test is what the property is used for, not how it is zoned, and it disqualifies a surprising amount of commercial property while allowing some residential.

I was quoted on this change in The Australian Financial Review on 11 August 2026. In the days since, the same question has come at me repeatedly from investors and from their accountants: which buildings actually qualify?

Almost every explanation I have read gets the answer half right. So here is the whole of it.

If you are earlier in the process and want the wider picture first, start with our guide to buying investment property with super. This article deals with one specific question inside it.

What is business real property?

Business real property is defined in subsection 66(5) of the Superannuation Industry (Supervision) Act 1993, the legislation governing every self-managed super fund. Two limbs, and both must be satisfied.

One, an eligible interest in real property. A freehold interest in real property, a leasehold interest in real property, or a qualifying interest in Crown land. A share in a company that owns land is not an interest in real property, which catches people out.

Two, that real property is used wholly and exclusively in one or more trades or businesses. It does not have to be run by the fund or its members. A tenant's trading activity counts.

That second limb is where every argument happens, and where most property investment plans come unstuck.

What "real property" actually means

Real property refers to land and anything fixed to it. Buildings, permanent structures, fixtures. It does not extend to the plant and equipment sitting inside, and it does not extend to a shareholding in an entity that happens to own land.

The interest has to be a real one. A licence to occupy is not enough. The fund needs an interest carrying exclusive possession of the property, which in practice means a freehold title or a genuine registered lease.

The business use test

Practitioners call the second limb the business use test, and it runs in two stages. Both have to clear before a property meets the definition of business real property.

Stage one, is a business being carried on? Somebody has to carry on a business on that land. Not necessarily your business. A tenant will do. But there must be genuine commercial activity with a profit motive, repetition and system behind it, rather than a passive holding or a hobby.

Stage two, is the property used wholly and exclusively in it? Every part of the land, all of the time. This is where the business use test is satisfied or lost. A property may clear the first stage comfortably and fail the second on a single room.

SMSF trustees should ask what is happening on the land today. Not what the council says it may be used for, not what the listing calls it, not what the owner intends.

An SMSF holding business real property gets two concessions no other property type receives, so the definition is doing real work:

• It is exempt from the 5 per cent in-house asset rule, which is what lets a fund lease to a related party.
• It can be acquired from a related party at market value under subsection 66(2)(b), which residential property never can.

Since 10 August 2026 it does a third job. It is the gateway for every new geared acquisition of land.

Why zoning does not matter

This is the single most common error I hear, and it runs in both directions.

A residentially zoned property used exclusively in a business can qualify as business real property. A commercially zoned one only partly used that way is not.

Councils zone land for planning purposes. The Tax Office asks a different question entirely, and the two answers do not have to agree.

What generally qualifies as business real property

• A standalone warehouse, factory or industrial unit on a single commercial lease.
• An office suite or consulting rooms leased to a business, with no residential component. Straightforward business premises.
• Retail space operating as a shop, with nothing let separately above or behind.
• The business premises your own company trades from. The SMSF buys them and leases them back at market rent, on arm's length terms.
• Farmland used in a genuine primary production business. A dwelling does not break it, provided the residential area is two hectares or less and primary production remains the predominant use.
• A motel with a manager's flat, or a pub with accommodation. The living space is part of running the business.

That last one surprises people, and it is the key to the whole test.

What does not qualify

• A shop with a flat above it let separately to a residential tenant. That flat has nothing to do with the shop.
• A surgery, pharmacy or clinic with the practitioner's own home attached. Private residence, not business use.
• Vacant premises. No business is being carried on there.
• Off-the-plan or newly built premises with no tenant at settlement. Same problem, and genuinely unresolved.
• Serviced apartments, short-stay and holiday letting. Residential units that are leased this way are treated as residential use even when income producing.
• Lifestyle blocks and hobby farms, where no genuine business is being carried on.

The distinction that decides it

Put the two lists side by side and one line separates them.

Same street. Similar building. Different answer.

The motel manager's flat exists because the business needs someone on site. It serves the business. The flat above the shop exists because someone needs somewhere to live, and it has no relationship to the shop at all.

The "wholly and exclusively" threshold

Those three words do most of the damage. They are not "mainly", "predominantly" or "substantially". A property that is 90 per cent business use is not 90 per cent qualifying.

There is one important qualification. Asked about mixed-use property, the Australian Taxation Office has said not all of it is automatically excluded, and that "the significance of any non-business use must be considered in the context of the arrangement".

That is the regulator declining to draw a bright line. Any non-business use of the property still has to be explained, and the burden sits with the trustee.

And here is the practical problem. Lenders are not waiting for context. They are declining anything with a residential component, because if the security is later found not to be business real property the loan itself may be non-compliant. A property can sit comfortably inside the ATO's stated position and still be unfinanceable.

Legally arguable and actually financeable are now two different things, and plenty of buyers will find that gap after they have exchanged.

What changed on 10 August 2026

Before 10 August, an SMSF could gear into residential or commercial premises through a limited recourse borrowing arrangement.

From that date, an LRBA can only be used to acquire land that meets the definition.

Grandfathered and unaffected by the new borrowing rule:

• Arrangements entered into before 10 August 2026.
• Refinancing of those arrangements.
• Binding contracts exchanged before 10 August 2026, even where settlement happens afterwards.
• Buying residential property outright, with no borrowing at all.

The measure is expected to raise about $50 million over the forward estimates. Only 11 per cent of SMSFs carry a loan at all, and it sits heaviest in funds holding between $500,000 and $1 million rather than the large ones the measure targeted.

What it does to buying power

The displaced buyer is specific. A fund with $200,000 to $400,000 available to leverage was reaching a $600,000 to $800,000 residential property. It no longer can.

That same fund is now competing for business-use assets in the $500,000 to $1.2 million band, mostly metro office and retail suites and small industrial warehouses. If you have not bought in this asset class before, our guide to commercial real estate investing covers how these assets are valued, leased and stress-tested, and it applies whether or not a fund is involved.

Lending against these assets inside super also runs at lower loan-to-value ratios, typically 60 to 70 per cent against 70 to 80 on residential, so the same deposit reaches a smaller asset. Lenders mortgage insurance is also not generally offered on SMSF lending, so unlike a purchase in your own name there is no way to use LMI to stretch a smaller deposit. What the fund has is what it can use.

For context on where the sector sits, Australian SMSFs held $120.1 billion in non-residential real property against $62.7 billion residential at March 2026, on total assets of $1.058 trillion. Roughly two to one, and it has been for years.

The 5 per cent in-house asset rule

An in-house asset is broadly one leased to, or invested in, a related party. No more than 5 per cent of a fund's total assets may sit in that category.

Business real property is excluded from that cap entirely.

That exclusion is what makes the strongest remaining strategy possible: the SMSF owns the premises your business trades from, and leases them back to you. Without the exclusion the arrangement would be an in-house asset of the SMSF and the 5 per cent cap would make it impossible at any meaningful scale.

Rent that was going to a landlord goes into your own superannuation instead, taxed at 15 per cent in accumulation phase and nil in pension phase, without consuming any of your contributions caps.

Get this wrong and it is expensive. The lease must be in writing, at genuine market rent, on arm's length terms, and reviewed. Under-renting to help the business along is exactly what auditors look for, and non-arm's length income is taxed at the top marginal rate.

Acquiring property from a related party

Section 66 prohibits an SMSF acquiring assets from related parties. Business real property is one of the few exceptions, under subsection 66(2)(b), provided the acquisition is at market value.

A related party of an SMSF means members, their relatives, their business partners, and entities those people control. The definition is wider than most people assume, and it is worth checking rather than guessing.

This is how business owners move premises they already hold into their fund.

How an SMSF can acquire the property

There is more than one route, and the new borrowing rule changes the ranking between them.

Outright purchase. The fund pays cash. No borrowing, no LRBA, no lender to satisfy. Simplest and now the most common answer for smaller funds.

In-specie transfer. You transfer premises you already own into the fund, either as a contribution counted against your caps, or as a sale at market value, or a combination. Only available because business real property carries the related party exception.

Related non-geared unit trust. The fund and the members hold units in a trust that owns the property, structured to satisfy the conditions in the SIS regulations. The trust cannot borrow and cannot have a charge over its assets. Useful where a fund cannot afford the whole asset, and unforgiving if the conditions are breached.

Tenants in common. The SMSF owns a share of the title directly alongside the members or another fund. Clean, but it makes any later sale a negotiation.

Limited recourse borrowing arrangement. The fund borrows through a bare trust. Since 10 August 2026 this route is only open where the property meets the business use test.

Which structure suits depends on the fund's cash position, the members' contribution caps, and the state duty consequences. This is an accountant's decision, not a buyer's agent's, and it should be settled before you make an offer.

Tax, duty and the costs that get skipped

Most of the surprises in this strategy are not about whether the property qualifies. They are about what the transfer costs.

Stamp duty. Payable on the transfer in most cases and calculated on market value, not on what you agree between yourselves. Treatment varies by state and some jurisdictions offer concessions in narrow circumstances. It is routinely oversimplified in adviser marketing, so get it confirmed for your state before you commit.

Capital gains tax. Moving premises you own into your fund is a disposal at market value, so CGT is triggered even though no money may change hands. Small business CGT concessions may reduce it. They may also not apply.

One thing worth saying plainly, because business owners ask it constantly. Inside super the deductions work differently from a property held in your own name. There is no negative gearing benefit to be had against your personal income, because a loss inside the fund can only be offset against the fund's own income. If the strategy only works on an after-tax basis in your own name, it does not automatically work in the fund.

GST. Commercial property sales can attract GST, and a fund that is registered may be able to claim input tax credits or use the going concern provisions. This is a live issue on most business premises and it needs to be priced in, not discovered at settlement.

Valuation. A market value acquisition needs to be supported. An independent valuation is the cheapest insurance in the whole exercise, and the lease that follows should be reviewed regularly on the same basis.

Common mistakes I see

• Assuming commercial zoning is enough. It is not, and this is the error behind most failed deals.
• Buying vacant premises intending to find a tenant later. The property must be in business use at the time it matters, not eventually.
• Letting the related party lease drift below market, or run without written terms, and inviting a non-arm's length income assessment.
• Treating a share in a company that owns land as an interest in real property. It is not.
• Ignoring the residential component because it is small. Wholly and exclusively means what it says.
• Committing to a purchase before confirming the fund can actually finance it under the new rule.
• Leaving the fund's investment strategy unamended after a large, illiquid asset lands in it.

The honest trade-offs

I am a buyer's agent and commercial property is what our commercial division buys, so take the following in that spirit. It is still true, and it applies to the asset class generally.

These assets generally deliver less capital growth than residential. The higher yield is compensation for that, not a bonus on top.

Vacancy is longer and more expensive. A tenanted asset can sit empty for six to twelve months while the fund keeps making loan repayments, and re-letting often needs incentives and a fitout contribution. In a fund paying a pension, that is a liquidity problem, not an inconvenience.

Concentration is real. One lumpy asset in a fund of a few hundred thousand dollars is a concentration problem whatever the yield. If it is also the premises of your own business, you have doubled down on a single outcome.

Exit is slower. When you need to sell the property, the buyer pool is thinner than residential and the sale can take months rather than weeks.

The settings may move again. An amendment has been flagged in Parliament and industry bodies are pushing for a carve-out on newly built premises. Anyone who needs certainty should factor that in.

For a meaningful number of people the right answer this year is to buy residential unleveraged, or to buy nothing at all. That is a legitimate outcome and nobody should be talked out of it.

Frequently asked questions

Where this leaves you

The rule is narrower than "commercial property" and stranger than "no residential". It turns on one question, and if you can answer that question you can assess most buildings yourself.

Everything else follows, and it should be reflected in the fund's investment strategy before any offer goes in.

If you own the premises your business trades from, the strategy in this article is worth a serious conversation with your accountant as part of a wider property investment strategy. If you are looking at a specific property and cannot tell which side of the line it falls on, that is worth a conversation before you spend money on a specialist opinion.

Once a property clears the business real property test, the harder question starts. In commercial property the lease is the asset, not the building, and two identical premises on different lease terms are worth very different amounts. That is a separate discipline, and it is what our commercial buyer's agent service exists to do.
