Premium Conversion is a pre-tax arrangement that allows the part of your salary that goes for health insurance premiums to be non-taxable. This means you save on Federal income tax and FICA taxes (Social Security and Medicare taxes). In most cases, you'll also save on State income tax and local income tax. The payroll office will sign you up for Premium Conversion automatically. You don't need to fill out a form.
