"""
- If you buy health insurance through the state- or federally run health insurance marketplaces, you can deduct only the portion of the premium you pay out of your own pocket. You cannot deduct the amount of any subsidy.
- If you buy an individual or family health insurance plan, either on the open market or through a marketplace, and you pay all of the cost out of pocket, then the whole amount is deductible.
