The employer/corporation provides health insurance to all employees, including outside sales.  Employees contribute through payroll deduction.  In this case, statutory employee pays $200/month.  Employer/corporation also has a 401k plan and provides a company match, even to outside sales/statutory employees.

Yes, there are some expenses but they are quite minimal in relation to the W-2 income.  It is primarily home based with travel to customers within a localized geographic area.  Occasionally travel to employer/corporation's local office for meetings, to drop off checks collected from customers, etc.
