About managing GST for commercial properties
Invoice Automate supports accurate GST on commercial properties where the owner is registered for GST. This prevents double-counting and ensures invoices meet Australian and New Zealand GST expectations when synced to Property Tree. Commercial leases generally attract GST when the lessor is registered, while residential rent is usually input‑taxed or exempt.
Before you start
Confirm these settings so GST is calculated and reported correctly.
Confirm the ownership is GST‑registered in Property Tree - When an ownership is registered for GST, Property Tree displays the ABN on tenancy invoices and treats amounts as GST inclusive by default
Verify creditor and account code setup - Property Tree uses the selected account code to apply GST rules to line items. Ensure default accounts are set for creditors, and BPAY details are correct if used
Check your Invoice Automate integration is active - Invoice Automate is embedded in Property Tree and supports a simple upload‑approve‑sync flow
Manage GST on a commercial tenancy invoice
Use these steps when processing invoices for a commercial property with a GST‑registered owner.
In Invoice Automate > Open the invoice that relates to the commercial tenancy
Check that the property is a commercial property and the ownership is GST‑registered
Ensure line items that attract GST are marked accordingly, and that any GST‑free items remain GST‑free. Property Tree applies GST based on the account code on each line
Check that the GST attributable to the owner’s taxable supply is shown once and that you have not added GST again on the same supply via a service account line. Commercial rent and most outgoings attract GS for GST‑registered lessors; do not replicate that GST on duplicate lines
