Property development inside a self-managed super fund (SMSF) is permitted, but the superannuation rules restrict it far more tightly than the equivalent activity in a company. There is no outright ban. A one-off development, funded from the fund’s own cash, held for the members’ retirement, and priced at arm’s length, can sit inside the rules. A geared, related-party, business-like development generally cannot. This guide sets out what an SMSF can and cannot do, what changed for SMSF property loans on 10 August 2026, and how the numbers change once borrowing is unavailable.
Anyone considering property development inside an SMSF needs a lawyer and an accountant engaged before they start. Every fund, every member, and every site is different, the consequences of a breach fall on the trustee personally, and the questions that decide whether a structure works are questions about a specific fund’s facts. This guide sets out the rules so that conversation starts from an informed position. It does not answer whether a particular arrangement is compliant, and no guide can. There is a list of the questions worth putting to those advisers at the end.
The area is governed by federal law, so the core rules are the same in New South Wales, Victoria, Queensland and every other state and territory. The Australian Taxation Office (ATO) is both the regulator of SMSFs and the tax office, which is why a single transaction can be a compliance breach and a tax problem at once. Superannuation is also a financial product, so advice on acquiring, holding or structuring an interest in one is regulated and has to come from someone licensed to give it.
Can an SMSF develop property at all?
Yes. No provision bans an SMSF from developing property, and the ATO says so directly. In its SMSF Regulator’s Bulletin SMSFRB 2020/1 on self-managed super funds and property development, the Commissioner states that “property development can be a legitimate investment for SMSFs” and that there is no concern where it complies with the superannuation law. The operative question is therefore not whether development is allowed, but whether a particular development can be structured so that it never breaches the rules.
That distinction carries weight because the consequences of a breach are severe. A serious breach can render the fund non-complying, which strips its concessional tax treatment and taxes an amount equal to a large share of its assets at 45%. The ATO can also force the sale of the development asset or the winding up of the fund. The remainder of this guide maps the points at which an otherwise ordinary development contacts a superannuation rule.
The constraining rules come from two instruments: the Superannuation Industry (Supervision) Act 1993 (the Act) and the Superannuation Industry (Supervision) Regulations 1994 (the Regulations). Five do most of the work: the sole-purpose test, the prohibition on borrowing, the ban on acquiring assets from related parties, the in-house asset limit, and the arm’s length requirement. Each is covered below. Read together, they explain why an SMSF development is structured differently from a conventional one, and why the fund’s cash rather than debt is usually the binding constraint.
What is an SMSF property loan, and why did the rules just change?
An SMSF property loan is almost always a limited recourse borrowing arrangement (LRBA), and from 10 August 2026 an LRBA can no longer be used to buy residential property. Trustees are generally prohibited from borrowing at all, and the limited recourse borrowing arrangement is one of the few exceptions, set out in section 67A of the Act. Under it, the fund borrows to buy one asset, the asset is held in a separate holding trust, and the lender’s recourse on default is limited to that asset and cannot reach the fund’s other investments. It has been the standard mechanism for SMSF gearing into property for more than a decade.
That route is now closed for residential property. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026, which received Royal Assent on 26 June 2026 following a parliamentary amendment agreed the previous day, changes the meaning of an “acquirable asset” so that an LRBA can only be used to buy real property that meets the definition of business real property. The ATO’s guidance on the changes to the LRBA provisions sets out three points that determine whether the change applies: it applies to arrangements entered into on or after 10 August 2026, it does not affect arrangements that existed before that date, and it does not affect the refinancing of those existing arrangements.
The effect is that the residential SMSF property loan, already restricted, is unavailable for new arrangements. What remains is a narrower path built around business real property and, more often, around funding development with the fund’s own cash rather than debt.
What still counts as an SMSF property loan after 10 August 2026?
A new LRBA can fund the purchase of business real property, and no other real property. Business real property, defined in section 66(5) of the Act (see section 66), broadly means land and buildings used wholly and exclusively in one or more businesses. A warehouse, a factory, a medical suite or a shopfront run as a business can generally still be bought with an SMSF property loan after 10 August 2026. A house, a townhouse, an apartment or a residential development site generally cannot, because residential premises are not used in a business in the required sense.
Commercial and industrial developers therefore retain a version of the borrowing tool that residential developers lose. Even then, the borrowing funds the purchase and not the build, for the reasons in the next section. An SMSF property loan after the change operates as a means of getting business real property into the fund, not as construction finance.
What happens to a loan already in place?
Existing arrangements are grandfathered and can still be refinanced. Where a fund exchanged a binding contract before 10 August 2026, the ATO’s guidance treats the arrangement as unaffected even if it settles or the loan is formally entered into after that date. An existing residential SMSF property loan can continue on its terms and be refinanced to a new lender without losing its protected status. What cannot occur is a brand-new residential arrangement entered into after the commencement date, and an arrangement that is unwound cannot later be replaced.
Why can’t you build with borrowed money, even under an existing loan?
Because borrowed money under an LRBA cannot be spent on improving the asset, and a development almost always changes the asset’s character. This rule applied long before the 2026 changes. The ATO explains in SMSFRB 2020/1 that the borrowing rules “do not allow for amounts borrowed under the LRBA to be used to improve the acquirable asset”, so while the loan can buy the land, “no amount of the borrowed funds can be put towards development costs”.
There is a second limb. Even where the build is funded from other money, if the works “fundamentally change the character” of the property, the arrangement can fail because the asset is no longer the same single acquirable asset the fund set out to buy. The ATO’s ruling on the key concepts, SMSFR 2012/1, and its guidance on the rules on the asset held under an LRBA state that “a property development will generally change the character of the property”. Demolishing a house and building three townhouses produces an asset that is not the asset the loan was secured against. That is a borrowing breach.
The workable position under a grandfathered loan is therefore narrow: borrowing can fund the purchase, works that constitute repair or maintenance rather than improvement are permitted, and borrowing cannot fund development. Development while an LRBA is on foot carries the character risk described above. For genuine development, the funding has to come from a source the borrowing rules do not reach, which in practice means the fund’s cash or an ungeared structure. For an SMSF, the feasibility question begins with the cash the fund holds rather than what can be borrowed against it.
Where do developers trip over the sole-purpose test?
The sole-purpose test is contravened when the development serves a goal other than the members’ retirement, and it is the provision the ATO applies where a structure is technically compliant but self-serving. Section 62 of the Act (see section 62) requires the fund to be maintained solely to provide retirement or death benefits to members. Any other purpose, called a collateral purpose, is a contravention, and the ATO lists it first among its concerns in SMSFRB 2020/1.
Three patterns attract attention. The first is a development that benefits a related business rather than the fund, for example where the fund carries the risk and cost while a member’s building company collects the work. The second is a fund that operates as a development business rather than an investor: the ATO draws a line between a one-off development undertaken as an investment and a pattern of buying, developing and selling that constitutes carrying on a business, and a super fund is not permitted to run a business of property development. The third is a decision that places the project ahead of the members, and the bulletin gives the example of a trustee who stops paying member pensions so the fund can direct more cash into a struggling development, which may show the fund is being maintained for the development’s success rather than the members’ retirement, breaching section 62.
Scale and repetition are themselves risk factors. A single, modest, cash-funded project held for retirement may sit within the test, depending on the fund’s circumstances. A staged, geared, multi-site program with a member’s construction firm performing the work has the characteristics of a business, which is the pattern the ATO identifies as contravening the sole-purpose test.
What do the in-house asset rules mean for a development?
The in-house asset rules cap how much of the fund can be tied up in related entities and related loans at 5% of the fund’s assets. Section 71 of the Act (see section 71) defines an in-house asset to include a loan to, or an investment in, a related party or related trust, and an asset leased to a related party. The fund must keep in-house assets below 5% of the market value of its total assets under section 82 of the Act, measured at 30 June each year, and it cannot acquire an in-house asset that would take it over the threshold. The ATO collects these restrictions on an SMSF’s investments in one place.
Five per cent is a small number in a development context. A fund holding $1 million in assets has a total allowable exposure to a related development vehicle of $50,000. Structures using a related trust or company therefore do not rely on the 5% headroom; they rely on an exception that keeps the investment out of the in-house asset count entirely. The main exception, the ungeared related trust or company, has its own conditions and is covered below.
Two other exceptions apply to funds that already own commercial premises. Business real property leased to a related party is not an in-house asset, so a fund can own a commercial building and lease it to a member’s business at market rent without breaching the 5% cap. Property held by the fund and a related party as tenants in common is generally not an in-house asset, unless it is leased back to a related party. Both are narrow, both depend on the property being and remaining business real property, and both sit under sections 66 and 71 of the Act. Neither assists a residential development, which leaves cash-funded direct development or an ungeared structure as the available routes.
What is the related-party trap, and how does the business real property exception work?
An SMSF generally cannot buy an asset from a related party, so a developer cannot sell their own site into their fund, and the principal exception is business real property. Section 66 of the Act prohibits the fund from acquiring an asset from a member or a related party, subject to a short list of exceptions. The fund is separately barred from lending to, or providing financial assistance to, a member or their relative under section 65 of the Act, so a development that supports a member’s finances contravenes that provision before the acquisition rules are reached. Residential land held personally sits inside the prohibition: it cannot be transferred into an SMSF, and the fund cannot buy it from the member, even at full market value.
Business real property is the significant exception. Under section 66, an SMSF can acquire business real property from a related party provided it is acquired at market value. Commercial or industrial land used wholly and exclusively in a business can therefore be moved into the fund at market value, which may be done partly as an in-specie contribution (covered below). The “wholly and exclusively” test is central, and the ATO sets out its application in its ruling on business real property, SMSFR 2009/1. Mixed-use property, a shop with a flat above it, or land with any material private use, can fail the test, and once it fails the exception is unavailable.
The exception turns on the property being and remaining business real property, and a development can change what the property is. Land that qualifies while it houses a business may not qualify once it becomes a residential development site, so the acquisition and the ongoing compliance of the structure during development may be connected questions rather than sequential ones. Acquiring at market value can also trigger transfer duty and capital gains tax (CGT) for the transferor personally, so a transfer into super can carry material cost.
Non-arm’s length income: why one bad price can cost 45%
Non-arm’s length income (NALI) is taxed at 45% instead of the concessional 15%, and property development is among the arrangements the ATO identifies as higher risk for it. The rule sits in section 295-550 of the Income Tax Assessment Act 1997 (see section 295-550). Where an SMSF and another party do not deal at arm’s length and the fund derives more income than it would have on commercial terms, that income becomes non-arm’s length income (NALI) and is taxed at the top rate, so the concession does not apply to it. On the regulatory side, section 109 of the Act separately requires the fund to deal at arm’s length, or on terms no more favourable to the other party, so one non-commercial dealing can be both a compliance breach and a tax problem.
A development is a chain of transactions, and non-arm’s length income (NALI) can be triggered at any link. The ATO lists the common instances in SMSFRB 2020/1: buying the land for less than market value, a related party providing building or professional services for free or below a commercial rate, borrowing on terms no commercial lender would offer, or the fund taking a return out of proportion to what it contributed. One recurring instance is a member who is a builder performing the construction at cost or without charge. Under the non-arm’s length expenditure (NALE) extension of the rule, incurring less than a commercial amount of expenditure in gaining the income can taint the income, so a discounted build can convert the entire development profit into non-arm’s length income (NALI) taxed at 45%.
Every transaction in the development, being the land purchase, construction, professional fees, any loan, and the split of proceeds, has to be documented and priced on commercial terms. The ATO notes that where parties are related there is an inference they are not dealing at arm’s length, and the fund carries the onus of rebutting it with evidence. In a feasibility, related-party involvement therefore carries full market rates rather than a discount, because the discount risks a 45% rate on the income.
How do developers actually structure an SMSF development?
There are four routes, and which one is available depends on who the other parties are and how the money flows. None permits development on the terms a conventional developer would use. The ATO discusses each in the appendix to SMSFRB 2020/1.
The first route is direct development by the fund, funded from cash. The fund owns the land outright and pays for the works from its own money, with no borrowing and no related-party discounts. This is the simplest structure to keep compliant, and its constraint is that the fund has to hold enough cash to buy the land and complete the build, which for many SMSFs is not the case.
The second route is an ungeared related trust or company, sometimes called a 13.22C structure, where the fund and related parties invest together in an entity that owns and develops the property. It permits members to pool their own money with the fund’s, and it is also where most contraventions occur; it is covered in the next section. The third route is a joint venture, where the fund contributes to a development alongside another party and shares in the proceeds in proportion to what it contributed. The fourth is investing in a genuinely unrelated development entity, where the fund is a passive investor and the related-party provisions largely fall away, though the arm’s length and sole-purpose rules continue to apply. The two middle routes carry the highest contravention risk and the first and fourth the lowest.
How does the ungeared unit trust (13.22C) work, and how does it break?
An ungeared unit trust permits an SMSF to invest in property development with related parties without the investment counting as an in-house asset, but only while it satisfies a list of conditions at all times, and a single breach is permanent. The exception comes from regulations 13.22C and 13.22D of the Regulations, and it is the structure the ATO encounters most often in SMSF property development. Where the conditions hold, the fund can hold a large stake in a related trust that owns the development. Where they fail, the whole investment becomes an in-house asset.
The conditions are set out in SMSFRB 2020/1: the trust cannot borrow, cannot hold an interest in another entity, cannot lease to a related party except for a legally binding lease over business real property, cannot acquire an asset from a related party (other than business real property), cannot run a business, and cannot give a charge over its assets. The conditions must be met when the investment is made and for as long as it is held. Ordinary development activity contacts these conditions repeatedly. Borrowing to fund the build breaches the no-borrowing condition. Granting a lender security over the land breaches the no-charge condition. Activity that grows into a business breaches the no-business condition.
The damage is permanent. The ATO states that once one of these events occurs, the investment “can never be returned to its former excluded state”, even if the problem is rectified. It becomes an in-house asset, and because the stake is usually well above 5% of the fund, the fund must then bring its in-house assets back under the cap within twelve months, which in practice can require selling the underlying property and ending the development. The bulletin’s worked examples include a fund forced to redeem units, and another in which a lender’s security over the trust’s land converts a $400,000 holding into an in-house asset and forces the land to be sold. A 13.22C structure has no tolerance for variation once established, which is what distinguishes it from active development.
Do you have to register for GST when an SMSF develops property?
Usually yes, because developing property to sell is carrying on an enterprise, and the same Goods and Services Tax (GST) rules apply to an SMSF as to any other developer. Where the fund’s projected turnover from the development is $75,000 or more, it generally has to register for GST and charge GST on the sale of new residential or commercial premises, and it can claim back the GST on its development costs. The ATO’s guidance on building and construction of residential premises treats a fund that builds and sells new premises as carrying on an enterprise, which is what brings GST into play.
The margin scheme applies as it does for any developer. Where available, it calculates GST on the margin between the sale price and the original purchase price rather than on the full sale price, which changes the after-tax result on a development the fund sells. The mechanics and the eligibility conditions are the same as elsewhere and are covered in our guide to GST on property development. The GST position is not altered by the developer being a super fund.
How is the development profit taxed inside an SMSF?
Inside an SMSF, development profit is generally taxed at 15% in accumulation phase, and the capital gains tax (CGT) discount does not usually apply to a development. The ATO’s guidance on how SMSFs are taxed sets the base rate at 15% on investment income in accumulation phase, and earnings on assets fully supporting a retirement-phase pension can be taxed at 0%. The comparable rates outside super are 25% or 30% for a company and up to 47% for an individual.
The qualification is the revenue and capital account distinction that applies to developers generally. A complying fund receives a one-third capital gains tax (CGT) discount on assets held longer than twelve months, giving an effective rate of about 10% in accumulation phase, but the discount applies only where the gain is on capital account. Property developed and sold is usually held on revenue account as trading stock, and revenue-account profit does not attract the discount, so a development sold at completion is generally taxed on its full profit rather than a discounted gain. The distinction is covered for developers generally in the guide to Capital Gains Tax on property development and the guide to income tax on development profit. A model applying an effective 10% rate to a build-to-sell project inside super is applying a discount the project will not generally qualify for.
The treatment differs for a development held rather than sold. A fund that develops to hold and rent holds the completed asset on capital account, earns rent taxed at 15% (or 0% in pension phase), and can access the one-third discount on an eventual sale after twelve months. The concessional rate in either case depends on the income remaining at arm’s length and outside the non-arm’s length income (NALI) provisions.
How much money can be contributed to develop with?
The contribution caps limit how quickly a fund can be topped up, which sets the practical ceiling on cash-funded SMSF development. Because borrowing to develop is unavailable, the fund needs enough cash to buy the land and complete the build. For the 2026-27 year, the concessional (before-tax) contributions cap is $32,500 a person and the non-concessional (after-tax) cap is $130,000 a person, per the ATO’s guidance on the non-concessional contributions cap. These caps have generally indexed upward over time.
The bring-forward rule can allow a person under 75 to contribute up to $390,000 of non-concessional contributions across three years, but access to it is tiered by total superannuation balance (TSB) at the previous 30 June. For 2026-27, the full $390,000 requires a total superannuation balance (TSB) below $1.84 million at 30 June 2026. Between $1.84 million and $1.97 million the bring-forward reduces to $260,000 over two years. At $1.97 million or above no bring-forward is available, though the annual $130,000 can still be contributed, and non-concessional contributions cease entirely once the total superannuation balance (TSB) reaches the general transfer balance cap, which is $2.1 million from 1 July 2026.
For a two-member fund where both members are below the $1.84 million threshold, a full bring-forward from each brings in up to $780,000 of after-tax money in one hit, on top of existing balances and concessional contributions. That funds a modest project, and it is well below the capital a geared developer deploys. The tiering means contribution capacity falls away as balances rise, so the funds with the largest balances have the least ability to add to them. In-specie contributions of business real property can also move value into the fund without cash changing hands, but they consume the same caps and trigger duty and capital gains tax (CGT) on the way in.
What varies by state, and what does not?
The superannuation rules do not vary by state; the taxes on the property itself do, and they apply to an SMSF. The sole-purpose test, the borrowing rules, the in-house asset limit and non-arm’s length income (NALI) all come from federal law, so they read the same in New South Wales, Victoria, Queensland, South Australia, Western Australia, Tasmania, the Australian Capital Territory and the Northern Territory.
Transfer duty (stamp duty) on the fund’s acquisition of land is a state tax, and the rates and thresholds differ in every jurisdiction, from Revenue NSW through to the State Revenue Office Victoria and each other state and territory revenue office. An SMSF pays it on acquisition as any other buyer does, and it is a cost line in the feasibility that the superannuation concessions do not remove. Land tax is also a state tax, and a fund’s status as a trust can change the threshold and rate that applies, so the land tax position is confirmed with the relevant state revenue office rather than assumed. Several states impose a foreign purchaser surcharge on duty and an absentee or foreign owner surcharge on land tax, and an SMSF with a foreign member or beneficiary can be caught. Revenue NSW, for example, can treat the trustee of a fund as a foreign person for surcharge purchaser duty where a beneficiary is not ordinarily resident in Australia. Where any member is a foreign person, the specific state’s rules apply before the fund exchanges.
Does any of this apply in New Zealand?
Not in the same form, because New Zealand has no direct equivalent of the SMSF, so a New Zealand developer cannot self-direct retirement savings into a development in the way an Australian can. KiwiSaver is the main retirement scheme, and it is not a vehicle for developing investment property. A KiwiSaver first-home withdrawal applies to a home the member intends to live in, not an investment or development project.
New Zealand developers holding property through companies or trusts are on a different footing, and the tax and GST treatment of a New Zealand development follows New Zealand rules, which we cover in the guide to GST on property development in New Zealand. For a New Zealand reader, the SMSF development strategy is an Australian one, and the local equivalents are questions of entity structure and the bright-line and GST settings rather than developing inside a super scheme.
How do the numbers work on a cash-funded SMSF development?
A cash-funded SMSF development models as an equity-only deal, because with borrowing unavailable the feasibility turns on the cash the fund holds and the timing of when it goes out and comes back. That is a different shape from a geared development. There is no senior debt, no capitalised interest, and no peak debt to manage. The binding constraint is whether the fund’s cash balance stays positive through construction, and whether the residual land value (RLV) the fund’s cash supports is enough to buy a developable site.
Three numbers do most of the work. The first is the residual land value (RLV): given the fund’s available cash and the build cost, the most the fund can pay for the land and still complete the project. The second is the month-by-month cash position: because the fund cannot draw on debt if it runs short, the model has to show the cash never goes negative, including a contingency for overruns. The third is the after-tax return at the fund’s 15% rate, tested against the applicable treatment, being revenue account for a build-to-sell and capital account for a build-to-hold, so the result does not assume a discount the project will not receive. The broader mechanics are covered in the approach to development cashflow.
There is also a concentration and liquidity dimension. An SMSF development places a large share of the members’ retirement savings into a single, illiquid project, with no ability to borrow through a cash shortfall and a compliance regime that can force a sale at a time not of the trustee’s choosing. The sole-purpose test frames that concentration as a question about the members’ retirement benefits rather than the return on the project.
What to ask your lawyer and accountant
The questions below are the ones that decide whether an SMSF development works, and none of them can be answered from a guide, because each turns on the fund’s own facts and documents. They are set out here so the first meeting starts further along.
- Does the fund’s trust deed permit direct property development, and does its investment strategy cover an illiquid, concentrated holding of this size?
- On these facts, is there a collateral purpose that puts the fund at risk under the sole-purpose test in section 62?
- Is the land business real property, and is it likely to remain so during and after the works? If it stops qualifying part-way, what happens?
- Does any part of the proposed structure create an in-house asset? If a 13.22C ungeared trust is proposed, which of its conditions is most at risk in this project, and what happens operationally if one is breached?
- Which related parties touch the land, the build, the finance or the professional services, and what evidence will the fund hold to show each dealing was on commercial terms if the ATO asks about non-arm’s length income?
- Is this project on revenue or capital account, and what does that do to the effective tax rate and to any capital gains tax (CGT) discount assumed in the numbers?
- When does the fund have to register for GST, is the margin scheme available, and from which invoice does the treatment need to be right?
- What transfer duty, land tax and any foreign purchaser or absentee owner surcharge applies in the relevant state, and does any member’s residency status affect it?
- If an existing LRBA is in place, do the proposed works change the character of the asset, and does anything planned put the arrangement at risk?
- Do the contribution caps and each member’s total superannuation balance allow the fund to be topped up as the cashflow assumes?
- Is this a case where a private ruling from the ATO is worth obtaining before committing?
The position in summary
An SMSF can develop property within a narrow set of conditions, and the 10 August 2026 changes narrow it further. Where a single, cash-funded project is priced at arm’s length at every step and held for the members’ retirement, the fund’s income is generally taxed at 15%, or 0% on assets supporting a retirement-phase pension, subject to the revenue-account treatment that applies to a build-to-sell. A geared, related-party, business-scale development is unlikely to fit, and the sole-purpose test, the in-house asset limit, the borrowing rules and non-arm’s length income (NALI) are the four provisions most often engaged. The restriction on residential SMSF property loans removes the mechanism most funds used to gear into property, leaving business real property and the fund’s own cash.
A structure that depends on gearing, on a related builder working below commercial rates, or on the fund operating as a development business, risks contravening one or more of those provisions, and the contravention is not generally cured by the structure. Whether a particular fund and a particular project fall inside or outside these rules is a question for a licensed SMSF specialist on the specific facts.
This guide is general information for developers, not financial, tax or legal advice. Superannuation is a financial product, and advice on acquiring, holding or structuring superannuation investments is regulated. SMSF development turns on the specific facts of a fund and a project, the rules and thresholds change, and the consequences of a breach are serious. Confirm the current position against the primary sources linked above, obtain licensed advice, and where the stakes justify it, consider asking the ATO for a private ruling before starting.
