Generally those premiums paid through an employer are pretax. If you are uncertain whether your health insurance premiums are taken out of your
paycheck pre-tax or after-tax Talk to your payroll department, or check
your W-2. If your premiums are paid with pre-tax money, that money will
not be included as income in Box1 (wages) on your W-2. If your premiums
are paid with after-tax money, that money will be included as income on
your W-2. If your premiums weren’t included as income on your W-2, you
cannot take them as a deduction because they’re already tax-free.
