Canadian payroll - employee moves to another company & Corp Taxx ID

Hello,

I just want to clarify what is supposed to happen when an employee moves to another company within the same organization and is assigned another Corporate Taxx ID. The BIN(first 9 digits) stay the same, the RP changes.

What YTDs are supposed to reset? Gross, DBAs, Fed Tax, CPP, EI ?

I believed any time the Taxx ID was changed all YTDs would restart.

I ask this because an issue was brought to our attention by an employee and we are seeing some strange things showing up. The Tax, CPP and EI YTD appear to be continuing on from the previous Taxx ID totals when output on the pay stubs. But the Gross and DBA YTDs were reset.
