“What’s the best structure for property development?” is one of those questions that has no single right answer — and the wrong answer can cost six figures.

The right structure depends on whether you intend to hold the developed property long-term or sell it, how many developers are involved, the GST treatment of the sales, the CGT exposure on the underlying land, stamp duty, asset protection from project risk, and how profits will be extracted at the end. A structure that works perfectly for a single-developer four-unit townhouse build is the wrong structure for a six-developer apartment block, and vice versa.

This guide explains the main structure options used for Australian property development, the tax and protection trade-offs of each, and the questions to work through before settling on one. It comes from our team at Trinity Accounting Practice — a Sydney-based registered tax agent practice that has advised NSW property developers on structure choice and project tax for over two decades.

The First Question — Are You Holding or Selling?

The most important fork in the road. “Property development” can mean two very different things from a tax perspective:

Develop to sell. The land and constructed property is trading stock in the hands of the developer. Profits are ordinary income (not capital gains). GST applies on the sale of new residential premises. CGT is largely irrelevant — the assets are stock, not capital.
Develop to hold (investment). The completed property is a capital asset producing rental income. Profits on eventual sale are subject to CGT. GST treatment is different — long-term residential rental is input-taxed; commercial is taxable.

The ATO looks at the actual intent at the time of development, supported by evidence (contracts, marketing material, finance applications). Trying to retrofit a “we always intended to hold” position when there are pre-sale contracts is a losing argument.

The Main Structure Options

1. Individual or Sole Trader

Develop in your own name.

Simplest setup. Existing TFN, ABN if needed for GST registration.
Profits taxed at your marginal rate. Big project, top marginal rate (47% including Medicare).
50% CGT discount available if you hold the property as a long-term investment (12+ months) — but not if it’s trading stock.
No asset protection. All your other assets are exposed to project liability.
Rarely the right answer for anything beyond a single, owner-built, hold-strategy project.

2. Private Company (Pty Ltd)

A company is incorporated to undertake the development.

Profits taxed at the company rate — 25% (base rate entity) or 30% for the 2025–26 income year.
No 50% CGT discount — companies don’t get it.
Limited asset protection. The company’s liability is limited to its assets, but director’s guarantees on bank finance often defeat the protection.
Profit extraction needs planning. Dividends to shareholders carry franking credits — but the cash is still taxed in the shareholder’s hands.
Good fit for develop-to-sell projects where the developer is happy to retain profit in the company or has a bucket-company strategy.

3. Discretionary (Family) Trust

A discretionary trust holds the project, with the developer’s family as beneficiaries.

Flexible distribution. Profits can be streamed to whichever beneficiary has the lowest marginal rate that year.
50% CGT discount available for capital gains on long-term holds — flows through to beneficiaries.
Asset protection is stronger than individual ownership but not bulletproof — depends on the trust deed wording and the appointor’s position.
Profits cannot be retained inside the trust at a low rate. Trust income is taxed at the beneficiary’s rate. Undistributed income is taxed at the top marginal rate (47%).
Good for develop-to-hold where annual rental income is being distributed to family beneficiaries. Less efficient for develop-to-sell, where one-off large profits are realised.

4. Unit Trust

A fixed unit trust where each developer holds units in proportion to their investment.

Common for multi-party projects. Each developer’s interest is clearly defined and proportional.
Income and capital gains flow through proportionally to unit holders — no entity-level tax.
50% CGT discount available on long-term holds where the unit holder is an individual or trust.
Stamp duty can apply when units are issued or transferred — depends on the state and on the trust’s underlying assets.
Good for joint ventures between unrelated developers.

5. Joint Venture (Contractual JV, not an entity)

Two or more developers enter a contractual JV agreement, each contributing land, capital or services. There is no separate entity — each JV partner declares their share of income and expenses.

No new entity required — each developer’s existing structure handles their share.
GST treatment depends on whether the JV is a “GST joint venture” under the ATO definition. A properly structured GST JV can simplify GST flow significantly.
Common in larger developments where each developer wants control over their own profit allocation.
Documentation is critical. Joint venture agreements need to be carefully drafted — most disputes between developers come from ambiguous JV agreements.

GST — The Single Biggest Property Development Variable

GST on new residential property is the single largest variable in most Australian property development tax outcomes. The high-level mechanics:

Sale of new residential premises is a taxable supply. GST applies on the sale.
The developer registers for GST and claims input tax credits on construction costs.
The margin scheme (where eligible) calculates GST on the margin between the sale price and the developer’s cost — typically a much smaller GST amount than the full 1/11 of the sale price.
The PAYG withholding at settlement requires the buyer to remit GST direct to the ATO from settlement proceeds.

Margin scheme eligibility, input tax credit timing, and the GST treatment of mixed-use developments are all areas where good structure advice early in the project pays for itself many times over.

Asset Protection — How Much Does It Matter?

If you have meaningful assets outside the project — a family home, investment portfolio, an operating business — asset protection should be a structure driver, not an afterthought. The two most common configurations we see for Sydney developers:

Project company owned by a discretionary trust. Project liabilities sit inside the company. Trust holds the shares for the family. Profits flow up via fully franked dividends, then distributed by the trust.
Unit trust for multi-developer projects, each developer holding units through their own family trust. Provides proportional flexibility while preserving each family’s separate asset protection.

A Trinity insight from 22 years in practice

The most expensive property-development structure mistake we’ve helped a Sydney client unwind involved a develop-to-sell project run through a family trust. The profit (around $1.4m) had to be distributed in the year of sale — there was no way to retain it in the trust at a low tax rate. Three of the four beneficiaries were already on the top marginal rate. The structure was wrong from day one for a develop-to-sell project. A simple company-with-bucket-company strategy would have saved the family hundreds of thousands in immediate tax and preserved working capital for the next project. Get the structure advice before the contract is signed — not after.

Stamp Duty — The State-by-State Trap

Property transactions attract stamp duty in every state. The traps for developers:

Land transfers between related entities can attract full duty unless a specific exemption applies.
Trust structures can be subject to “land rich” or “landholder” duty regimes when units or shares are transferred.
NSW foreign investor surcharge duty applies if any beneficiary, unit holder or director is a “foreign person” under the definition.

Stamp duty needs to be modelled into the structure decision from day one. State revenue offices do not care that you “didn’t realise.”

What This Means for You

If you are planning your first development: get a structure review before you sign the land contract. Once the land is in the wrong entity, restructuring almost always triggers duty.
If you have a project mid-way through: verify the structure still works for the actual end-state (hold vs sell). If your intent has shifted, the structure may need to as well.
If you are entering a joint venture: get the JV agreement drafted by a lawyer experienced in property development, and have your accountant review the tax flow before signing.
