Single Touch Payroll (STP) is an initiative introduced by the Australian Tax Office, replacing the PAYG end of year reporting process with a per-pay transmission updating the ATO with information about each employee in the pay and their Year To Date details.
Reporting to the ATO via STP and will be mandatory for all employers with 20 or more employees (by head count), from 1st July 2018.
Support for STP will be incorporated into a new major release - Synergetic v69, due Q2 2018.
