The RPN (Revenue Payment Notifications)
- The RPN files replace the old P2C files that businesses used to download from ROS for employees
- Each employee in Payroll will have an RPN retrieved from ROS. It details their rates, thresholds, cut-offs and the YTD values for previous employments
- If an RPN is not available for a new employee, the service will attempt to create a new RPN for that employee. The employee needs a PPSN number and Employment ID in their payroll Employee record
- Step 2 of every pay run checks the RPNs with ROS. If needed, the system will retrieve RPNs to apply to employees
