The potential loss of social security benefits increases each year that employees continue to participate in POP because there is no social security deducted from their share of out-of-pocket health/dental premiums. However, it should be noted, that it would take many years of continued participation in POP before the social security benefits lost exceeded the tax savings realized each month. Employees concerned about either the low income impact or their social security benefits should be advised to seek the advice of a qualified tax consultant. Employees have days from the date they first become eligible for POP to disenroll. Thereafter, all POP enrollees may disenroll each year during the annual open enrollment period by completing Attachment G - Premium Only Plan (POP) Disenrollment Form (CalHR ).
