It depends. In most states, if your income is below 150 percent of the federal poverty level, you can enroll in a Marketplace plan year-round. Additionally, if you are currently enrolled in a Marketplace plan and become newly eligible for cost-sharing reduction subsidies (CSRs), or if you’ve had a change in eligibility for CSRs, you should qualify for a special enrollment so long as you apply within 60 days of your change in status. If you are newly eligible for CSRs, you may enroll in either a silver plan or within the same metal level as your current plan. (45 C.F.R. § 155.420.)
Note: In most states, if your income is below 138 percent of the federal poverty level, you may be eligible for Medicaid, which is open for enrollment year-round.
