I'm trying to get my head around Single Touch Payroll. I own my own business and therefore have no problem with what I need to do for my employees. Problem is that I also work for two other businesses (help with BAS lodgement monthly/qtrly)that use Reckon, one of which has a different employee that does the payroll. Do I just need to add the other two businesses to my own business Reckon Portal login and then use that software ID in each separate businesses AUSKEY to get started? I then have to add the payroll staff to the business where I don't do the payroll so that they can do the STP? The additional payroll staff would also need to register on the Reckon Portal and get MFA. Is this process correct?
