Why STP?
Basically, it's a more efficient way to run the taxation system. In theory, it also makes it harder to operate in the 'black economy' because the ATO has a better understanding of who is being paid what and when. Single Touch Payroll is designed to streamline business reporting and help the ATO monitor whether employers are complying with their Superannuation Guarantee and PAYG Withholding obligations. By reporting through Single Touch Payroll, employers need not complete Pay-As-You-Go Withholding Activity Statements throughout the year and Payment Summaries will be available to employees through MyGov.
