When a property developer sells a completed project, the instinct is to ask how much capital gains tax they will pay. The more important question is whether CGT applies at all, or whether the entire profit is taxed as ordinary income with no discount available. It is a question every property developer accountant in Australia should be asking from day one.
Three possible tax treatments exist for property development profits in Australia: income from a business of property development, a profit from a profit-making undertaking or scheme, and a capital gain from the mere realisation of a capital asset. Each produces a materially different tax outcome, and the facts that determine which applies are often locked in long before you sign a contract of sale.
This is not a theoretical concern. On a $100,000 development profit, the difference between capital and revenue treatment exceeds $20,000 in additional tax at the top marginal rate, and that gap widens significantly on larger projects or where the developer is earning other income at a high marginal rate. We work with property developers across Australia, including Melbourne and Brisbane, to get this right before it becomes a problem. Our property development tax advisory service is the right starting point.
Why the Distinction Matters So Much
If your development profit is treated as a capital gain, individuals can apply the 50% CGT discount before tax is calculated, and trusts can pass that discounted gain through to beneficiaries who apply their own discount. The tax base is effectively halved before any rate applies.
If the profit is treated as being on revenue account, whether as business income or as proceeds from a profit-making undertaking, the 50% CGT discount does not apply at any level. The full profit is assessable as ordinary income. On top of this, GST may apply to the sale, further reducing your net return. The interaction between GST and property development is a complex area in its own right. See our related article on how the GST margin scheme works on a development sale for more detail on when GST applies and how to reduce the liability.
The distinction also affects whether the main residence exemption can apply, whether pre-CGT asset status is preserved, how capital losses interact with the gain, whether small business concessions are available, and the timing of when tax becomes payable. Getting the classification wrong has consequences across multiple areas of tax law simultaneously.
The Three Categories Explained
1. Business of Property Development
A taxpayer is carrying on a business of property development where their activities are systematic, organised, carried on in a businesslike manner, and conducted on a regular or continuous basis. Indicators include maintaining a business plan, keeping commercial records, employing or engaging contractors as a regular course of activity, and deriving income from development as a primary or significant pursuit. TR 97/11 provides the ATO's guidance on what constitutes a business in this context.
2. Profit-Making Undertaking or Scheme
A profit-making undertaking can arise even from a single, isolated transaction. The key is whether the transaction has the character of a commercial dealing, with a purpose of profiting from the development and sale. This is where many first-time developers are caught: they assume that because they have never developed before, the outcome must be capital. That assumption is wrong. As the courts have confirmed, a single transaction conducted in a commercial manner, with a clear profit purpose from acquisition, is a revenue account event.
3. Mere Realisation of a Capital Asset
Where a property was genuinely acquired for long-term investment or private purposes and is subsequently sold, sometimes with minor subdivision or improvement, the proceeds may be treated as the mere realisation of a capital asset. In this case the 50% CGT discount is available and GST generally does not apply to the sale. This was the position in the Peter scenario: an industrial property held for long-term rental, rezoned by council without the owner's initiative, and sold to an unsolicited purchaser with no development works completed.
