More detail

What an S corporation costs to run

Starting figures. New employers start at 2.4 percent unemployment. A family corporation that employs only family members who each own at least 50 percent can elect out of Hawaii unemployment under HRS 383-7(20). If yours has, put zero. Other payroll cost means TDI, prepaid health care and workers comp, where they apply to you as the owner.
