Are life insurance procees taxable if the employer paid the premiums?

No. Life insurance benefits are not eligable for taxation unless the insured passed away without assigning a beneficiary. In this situation the benefits are paid into the deceased's estate and are subject to any back taxes or child support owed by the deceased, or the would be inheritor. Cash value is not the same as an insurance benefit and may be taxable in some situations. Group (employment) insurance has no cash value.
