Before you can send data such as STP events or tax file number (TFN) declarations, you will need to connect your portal to the ATO.
This is required for all sending methods as the data files require the same information as the webservice.
Go to Config > Company Management > select the entity.
In Entity Details, set the Entity Name, Trading Name and ABN (with no spaces).
In the Payroll tab, enter the Payroll Address (in its entirety, including country)
In the Tax Office Settings section, enter the ATO Signatory. This is the user who will be identified as signatory when TFN declarations or STP events are submitted.
