Throughout the platform you can enter costs and revenue as GST inclusive, exclusive, or exempt.
Feasly automatically standardises all amounts to Ex GST for consistency across your feasibility.
Why GST is kept separate
GST doesn’t represent a true project cost — it’s a tax flow, not a profit driver.
Keeping GST separate ensures your feasibility reflects the real financial position of your project by:
Maintaining consistent logic across all sections.
Preventing inflated margins or incorrect returns.
Providing a clear distinction between project performance and tax obligations.
The Margin Scheme Exception
There’s one GST scenario that can impact project profit — the Margin Scheme.
Under the Margin Scheme, GST is collected on sales but may be calculated at a reduced effective rate (often around 7%).
Because you’ve collected GST on sales but pay back less GST to the ATO, the difference:
Improves free cashflow, and
Increases net project profit.
It’s not as simple as adding the Margin Scheme impact into cashflow Ex GST, as that mixes tax and project performance.
Coming soon: Feasly will introduce a GST toggle (Ex / Inc) in Cashflow— the same function used in Summary — so you can see this impact clearly.
Summary Section: GST Views
Switch between:
GST Exclusive – Standard feasibility view showing true project profitability.
GST Inclusive + GST Position – Updates all values across your feasibility to assess total exposure, tax flows, and timing.
Financials Section: GST Summary
The GST Summary is a monthly cashflow-based report (not a tax outcome) automatically generated in the Financials section.
Use it to:
Track GST payable and refundable.
See GST split by Debt and Equity funded costs.
Account for Margin Scheme or Land Purchase Tax Credits.
Forecast GST cashflow impact, timing, and cumulative position.

Seek Professional Advice
GST treatment varies by project, entity structure, and funding.
Common considerations include:
Using the Margin Scheme or claiming land tax credits
Requirements for separate GST accounts (some lenders require this)
What’s exempt, claimable, or not claimable for your entity
How your accountant reports GST (e.g. monthly vs quarterly)
Feasly gives you the flexibility to model GST, but your accountant will ensure it’s applied correctly to your specific circumstances and project.
