Open vs special enrollment
Annual open enrollment typically runs November–January. SEPs trigger after job loss, marriage, birth, or moving. Missing windows can leave gaps unless you qualify for Medicaid or a short-term plan.
Subsidies and metal tiers
Premium tax credits reduce monthly premiums based on income vs federal poverty level. Cost-sharing reductions lower deductibles on Silver plans for qualifying households.
