All Australian businesses need to be using Single Touch Payroll (STP) software to run payroll.
You do have a few options with how you do this. You can choose to run payroll yourself using software.
You can hire an accountant, bookkeeper or payroll manager to do it for you. STP approved software such as Payroller provides an Agent Portal for accountants, bookkeepers and tax agents. You can easily invite your accounting professional to manage your payroll using Payroller on your behalf.
What option you choose ultimately comes down to your budget and your own confidence with running payroll on your own.
