Within Property Tree, if you have an Owner as marked as a 'Registered for GST' Invoice Automate will display a 'Owner Registered for GST' tag in the Owner Details section.

When creating a Tenancy Invoice through Invoice Automate, the system will include an added Owner GST amount to the Tenancy Invoice Amount, and the GST and Exc GST should be calculated and updated in relation to that Invoice Amount in the Tenancy Invoice.

If an Owner is marked as a 'Registered for GST' in the PT system, the system will display a 'Owner Registered for GST' tag in the Bulk Review section.
