I have an existing client where they have 3 separate businesses all operating under 1 umbrella (same business #).   The 3rd business is new and is a retail outlet and they will now have a couple of employees.  They plan on hiring a payroll provider to do the payroll for the employees.   For the owner, she used to take dividends but with the new company she wants to draw a salary but doesn't want to use the payroll provider for that as the bank account won't have enough funds in the first while to pay her employees and her so she asked if I could do the payroll on my end just for her.    The issue I see with this is I don't know if CRA will allow 2 different T4 summaries to be filed under the same business number (one by me and one by the payroll provider).  Their accountant recommended they use a payroll provider even though I could do it using Sage.  I suggested she find out from the payroll provider if they are able to withdraw her salary from a different bank account for a while until there is enough in the store's bank to cover her employees and hers.  Each of the 3 businesses have their own bank account.
