Hi lando,
Welcome to QuickBooks.
Let's make sure that Electronic Lodgement is enabled so you can successfully add each employee without any error. Let me walk you through how.
- Click Employees.
- Go to the Payroll Setting tabs.
- Select ATO Settings.
I have attached a screenshot for your visual reference.
Then, follow the instructions to enable electronic lodgement. Once done, you can start adding your employees.
