We have been asked to take over the payroll processing for a company with 80 employees for July. The previous payroll agents were using IRIS System whereas we are using Sage 50 Payroll Software. Am I correct in assuming that in addition to usual employees' details, i.e. Name, NINO, Address, we also need the long 16 character RTI Works/Employee number to be copied over into our Sage System (along with other details and Year-to-Date values) ? When we asked the previous payroller, this was the first time they had heard about RTI Employee reference to be used this way. The worrying thing is the fact they had acquired this client from an earlier agents using Sage. They seem to have successfully e-filed June FPS without thinking twice about obtaining the RTI no's from the previous agents. Can you please help as we are getting conflicting views and opinions from Software providers as well as from HMR&C.
