A successor employer who has acquired all or part of a business and who has immediately succeeded the former employer as the new employer of an employee, may, under certain circumstances, take into consideration the CPP/QPP, EI and provincial parental insurance plan (PPIP) deductions already withheld by the previous employer and continue withholding and remitting such deductions as if there was no change in employer. If employees have already paid the maximum deductions, no further deductions would be taken for the year.
See Employer restructuring/Succession of employers to see if you can benefit from these legislative changes.
If these legislative changes do not apply to your business, even though some employees paid the maximum CPP/EI deductions for the year before the restructure or reorganization, you may want to ask for administrative relief for your employees by submitting a written request for relief to your tax services office.
