Single Touch Payroll (STP) Phase 1 was switched off on 27 February 2025. To start reporting your payroll to the ATO again, you must move to STP Phase 2 (Payroll menu > Single touch payroll reporting > Move to Phase 2).
If you haven't made the move to STP Phase 2 and you've processed pays after STP Phase 1 was shut down, see what you need to do.
