Key takeaways
- Stage-based cost tracking reveals true profitability. Code costs by project and stage to make timely decisions and keep lenders confident.
- GST rules are project-critical. Know when GST at settlement applies, when the margin scheme can be used, and how to manage BAS and credits.
- A simple setup beats spreadsheets. Configure your chart, tracking, bank rules, and approvals once to automate reconciliation and reduce errors.
- Real-time reporting drives outcomes. Use dashboards and KPIs to watch WIP, cash burn, and margin, then course-correct before costs blow out.
What is property development accounting?
Property development accounting is the practice of tracking costs, revenues, and profitability across a development's full lifecycle, from land purchase through design, construction, and settlement.
For real estate accounting and accounting for property development, the challenge is matching costs to the right stage and project so you see true margins before it's too late.
Why it's different:
- Track each project separately: A Parramatta townhouse has different costs than a Brisbane commercial build
- Projects span years, with land in year one, approvals in year two, build in year three, sales in year four
- Costs accumulate, but revenue comes at the end
- You need to manage WIP, track development costs by stage, and recognise revenue correctly
Why track costs across project stages?
Stage tracking shows where money is going and whether you're on budget.
- Spot blowouts early. If you lump everything together, you won't know if problems are in earthworks, structural, or finishing until it's too late.
- Keep lenders happy. Banks want detailed breakdowns. Having this in your system saves hours of manual work.
- Forecast better. If structural came in 10% over, you can adjust forecasts for remaining stages.
Typical stages: land acquisition, planning/approvals, siteworks, building construction, sales/settlement. Within construction: foundations, frame, roofing, services, fit-out.
How to set up your accounting for property projects
Get this right once and save time on every project.
- Set up tracking categories. Create 'Project' and 'Stage' tracking categories in your accounting software so you can tag every transaction to the right job. This gives you instant visibility into costs by project and phase and saves you time digging through spreadsheets. Learn more about project tracking.
- Separate direct costs from overheads. Direct costs hit a specific project: land, construction contracts, consultant fees, materials. That split usually breaks down into hard costs (construction, land, materials) and soft costs (permits, legal, design and consultants). Overheads keep the business running but aren't tied to one job: office rent, admin salaries, insurance. Getting this split right from the start means your project margins actually mean something. See construction job costing.
- Set up suppliers correctly. Capture ABNs, business addresses, and payment terms upfront. You'll need this for TPAR reporting, and it saves chasing details at year-end when you're already busy.
- Create bank rules. Auto-code recurring transactions, like regular supplier payments or equipment hire, to the right project. Review your rules quarterly to catch any that need updating as projects wrap up or new ones begin. Clean coding also keeps your cash flow position easy to read at a glance.
- Set up approvals. Use apps like ApprovalMax to set spending limits and approval chains before costs get out of hand. This is especially useful when you have site managers or project leads authorising purchases.
- Get GST codes right. Margin scheme, commercial taxable, input-taxed residential: each needs different treatment and mistakes are expensive to fix. Work with your accountant to set up the right codes before your first transaction, not after.
Accounting for costs from land to settlement
Property development moves through distinct phases, each with its own accounting treatment. Here's what to track at every stage.
- Land acquisition: Capitalise the purchase price, stamp duty, legal fees, and interest on land loans to work in progress (WIP). These costs stay on your balance sheet until you recognise revenue at settlement and not when you pay them. Keep supporting documents organised from day one, as you'll need them for audits and financing.
- Planning and approvals: Architect fees, engineering, consultants, surveys, and council fees all go to WIP. These costs add up quickly, especially on complex sites with rezoning or environmental requirements. If you're working in a joint venture, track each party's contributions carefully in separate equity accounts as messy records here create headaches when it's time to split profits.
- Construction: This is usually the biggest cost category: construction contracts, subcontractors, and materials. Strong processes here protect your margins. See the construction accounting guide.
- Progress claims: Verify the work is complete, obtain the required certificates, then process payment. Don't pay ahead of verified work.
- Loan drawdowns: Match each drawdown to the corresponding progress claim for clean reconciliation and easier reporting to lenders.
- Variations: Update your project budget immediately when a variation is approved, not at the end of the month. Small delays in recording changes make it harder to see your true position.
- Sales and settlement: Deposits are liabilities, not revenue. They sit on your balance sheet until settlement completes. Revenue recognition under Australian accounting standards, for residential property held as trading stock, typically means recognising at settlement rather than contract signing. Work with your accountant to finalise GST using correct settlement statements, as errors here can trigger ATO adjustments.
How GST applies to property development
GST in property development accounting isn't straightforward and the rules depend on what you're selling and how you acquired it. Here's a quick overview, but always confirm the details with your accountant.
You must register for GST once your turnover reaches $75,000 or more in a 12-month period. Since 1 July 2018, GST at settlement has also applied to new residential premises and new residential land, so the buyer withholds the GST from the price and pays it directly to the ATO. Where the margin scheme applies, the amount withheld is 7% of the contract price. For the day-to-day mechanics, it helps to have your GST tracking set up before your first sale.
- Margin scheme (residential): You pay GST on the margin (sale price minus what you paid) rather than the full sale price, which usually means lower GST. Use the ATO's GST property decision tool to check if you're eligible. The trade-off? You can't claim input credits on construction costs. See the ATO's residential property GST info for more detail.
- Commercial property: Fully taxable. You charge GST on the sale and claim input credits on your costs. It's simpler to manage, but the GST liability is higher.
- Land sales: Residential land is usually input-taxed, meaning no GST on the sale and no credits to claim. But subdivisions and land development can change things so get specific advice before assuming.
- BAS reporting: If you're on accrual accounting, you report GST when invoices are issued, not when cash moves. This matters for cash flow planning, and it means your records need to be detailed, especially if you're using the margin scheme.
Is profit capital or revenue for tax?
This distinction can significantly affect your tax bill. If your profit is treated as a capital gain, individuals and trusts can access the 50% CGT discount on an asset held for at least 12 months, which halves the taxable gain. Ordinary income is taxed at your full marginal rate.
The ATO looks at several factors:
- Are you in the business of developing property?
- Do you have a history of buying, developing, and selling?
- What was your intention when you purchased?
- How long did you hold?
- How many projects have you completed?
If you're developing regularly, the ATO will likely treat your profits as ordinary income.

FAQs on property development accounting
These quick answers cover the questions developers ask most about day-to-day property project accounting. Use them alongside advice from your accountant.
Accrual or cash accounting?
Most developers use accrual as it matches revenues/expenses to when earned/incurred, giving accurate pictures on long projects. Check with your accountant.
How do I handle joint venture contributions?
Joint ventures need separate equity accounts per partner. Allocate costs by agreed profit-share. Use a detailed JV agreement.
Can I track profitability by lot?
Yes. Create sub-tracking for 'Lot'. Allocate direct costs to specific lots, shared costs by floor area. More coding work but valuable insights.
How should I treat loan interest?
Capitalise interest on development loans to WIP during development. Once complete and ready for sale, expense further interest as period costs.
What reports do lenders want?
Budget vs actual by stage, drawdowns against limits, profitability forecasts, WIP balances. Plus presales, construction progress, valuations.
