Avoid these SMSF Development Site Mistakes

Buying a development site through your SMSF is no longer a residential property strategy.

The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 changed the rules for limited recourse borrowing arrangements. From approximately 10 August 2026, new LRBAs can only be used to acquire real property that satisfies the definition of business real property under section 66 of the SIS Act, and residential property does not meet that definition. If you're a registered nurse considering an SMSF loan to purchase land, the classification of that land determines whether borrowing is permitted at all.

Why Most Development Sites Don't Qualify

Vacant land not currently used in a business does not qualify as business real property. Business real property means land and buildings used wholly and exclusively in one or more businesses. A block of land purchased with the intention of subdividing or building residential dwellings falls outside this definition because the intended future use is residential, not commercial. The definition depends on actual use at the time of acquisition, not what you plan to do with the property later.

Consider a nurse practitioner with $400,000 in their SMSF who identifies a vacant 1,200-square-metre block zoned for medium density residential development. Under the pre-2026 rules, this would have been a potential SMSF purchase using an LRBA. After the ban, the vacant land cannot be acquired using borrowed funds because it is not currently used in a business. The SMSF could purchase the land outright if the trustee had sufficient existing fund assets, but borrowing is prohibited.

When a Development Site Can Be Acquired with Borrowing

A development site may qualify if it contains a commercial property used wholly and exclusively in a business. A property zoned mixed-use or commercial that currently operates as a warehouse, office, or retail premises and is used in a business can meet the definition. The business does not need to be operated by the SMSF itself.

In a scenario where a clinical nurse specialist locates a 600-square-metre commercial site with an older workshop building leased to a plumbing business, the property may satisfy the business real property test provided the workshop is used wholly and exclusively in the plumbing business and no part of the site is used for domestic or private purposes. Where the property contains a dwelling for private or domestic purposes, it can still qualify if the dwelling occupies no more than 2 hectares and the main use of the whole property is not domestic or private. If the site is being acquired because the existing tenant is leaving and the buyer intends to demolish the workshop and build residential units, the classification at the time of acquisition is what matters. Once the business use ceases, the property no longer meets the definition, and the SMSF may be in breach of the sole purpose test if the property is not being used to provide retirement benefits.

The Single Asset Requirement and Multiple Titles

Multiple real property titles cannot be acquired under a single LRBA, and an exception applies where the properties are distinctly identifiable as a single asset, meaning they are identifiable, have equal market value, and are bought and sold together. This creates a problem for nurses looking to acquire adjoining blocks or a subdivided site held on separate titles. Even if the two blocks are side by side and purchased from the same vendor at the same time, they are treated as two separate assets and cannot be acquired under one LRBA.

A registered nurse with a $600,000 SMSF balance may find two adjoining commercial lots, each with a small retail tenancy, available for purchase as a combined sale. If the lots are on separate titles, the SMSF cannot borrow to acquire both under a single arrangement. The trustee would need to acquire one lot with borrowing and the other with existing fund assets, or acquire one lot only. Properties on separate titles do not qualify even if substantially similar.

Related Party Leasing and Arm's Length Terms

If the business real property is leased to a related party of the fund, the lease must be on arm's length terms at market value. Business real property leased between the fund and a related party of the fund is excluded from the in-house asset rules, but any such lease must be made on arm's length terms at market value. For nurses operating a private practice or a company that provides clinical services, leasing commercial premises from your SMSF is permitted, but the rent must reflect what an unrelated tenant would pay for the same premises.

An aged care nurse who operates a consultancy business through a company might purchase a small office using an SMSF loan and lease it to her own company. The rental income flows to the SMSF, and the company claims a tax deduction for the rent paid. The arrangement is only compliant if the rent is set at market value and reviewed regularly. Overcharging the company or undercharging to benefit the business both create compliance risks. SMSF loans for nurses involve stricter rules than standard investment loans for nurses, and the penalties for non-compliance include loss of concessional tax treatment and potential disqualification of the fund.

Contract Date Versus Settlement Date

The 2026 residential ban applies based on the date of contract exchange, not the settlement date. A contract exchanged before the operative date is protected even if settlement occurs after the ban takes effect, and no action is required by trustees with existing compliant residential LRBAs. This grandfathering provision does not extend to new contracts entered after the commencement date, even if the purchase was under negotiation before the law changed.

A midwife who exchanged contracts on a residential development site on 5 August 2026 with settlement scheduled for September would have a grandfathered arrangement. A midwife who exchanged contracts on 12 August 2026 for the same type of property would be unable to proceed with SMSF borrowing. The two-week difference determines whether the LRBA is permitted. If your existing SMSF loan relates to residential property and was entered before the commencement date, you can continue to hold and refinance the arrangement without triggering the new rules, provided the refinancing does not constitute a new LRBA under ATO guidance.

Contributions and Balance Limits from 1 July 2026

Increasing your SMSF balance to reduce the amount you need to borrow requires contributions within the annual caps. The concessional contributions cap is $32,500 per annum from 1 July 2026, and the non-concessional contributions cap is $130,000 per annum. For nurses with significant savings or equity in other property, non-concessional contributions can be brought forward over three years, allowing up to $390,000 to be contributed in a single year if your total superannuation balance on 30 June of the previous year was below $1.84 million.

A community health nurse in her early 50s with a current SMSF balance of $320,000 and $180,000 in equity from her principal place of residence might use a refinancing strategy to release that equity and contribute it to super as a non-concessional contribution. If her total superannuation balance was below the threshold, she could contribute the full $180,000 in one year under the bring-forward rules. Combined with her existing balance, the fund would hold $500,000, which could then be used to acquire a commercial property outright without needing to borrow. This approach avoids the LRBA restrictions entirely and eliminates loan servicing costs within the fund.

Division 296 Tax on Large Balances

From 1 July 2026, where a member's total superannuation balance at the end of the financial year exceeds $3 million, Division 296 tax of 15 percent applies to the proportion of earnings attributable to the amount above that threshold. Where the total superannuation balance exceeds $10 million, an additional 10 percent Division 296 tax applies to the proportion of earnings above that threshold. For nurses with higher SMSF balances, the tax treatment of returns from a commercial property acquired through the fund becomes part of the overall calculation.

Outstanding LRBA amounts entered into on or after 1 July 2018 are included in a member's total superannuation balance in certain circumstances, including where the LRBA is with an associate of the fund or where the member has satisfied a condition of release with a nil cashing restriction. This means borrowing within your SMSF can push your balance over the $3 million threshold for Division 296 tax purposes even though the borrowed amount is not technically part of the fund's net assets.
