Single Touch Payroll (STP) is an initiative by the ATO which, in simple terms, means that any time you process employee-related pay data, the ATO needs to be notified electronically at the time the payment is made.
As of the 1st July 2019, all business that pay employees are required to report to the ATO using Single Touch Payroll. The employee’s salary/wages, pay as you go (PAYG) withholding and superannuation must be reported to the ATO each time you pay them.
