Miss December 15 and January Has No Coverage: The 2027 Open-Enrollment Dates, the $12,000 Out-of-Pocket Cap, and 3 Checks Before November 1
Open enrollment for 2027 Marketplace coverage starts on November 1, 2026, on HealthCare.gov. Two deadlines do two different jobs, and confusing them is the expensive mistake. December 15, 2026, is the last day to enroll or change plans for coverage that starts January 1, 2027. January 15, 2027, is the last day to enroll at all. A person who enrolls on December 16 has not missed open enrollment, but has missed January: that coverage starts February 1, 2027, once the first premium is paid. If a current plan ends December 31, that is a month with no coverage and no cap on what an emergency could cost. ✅ Miss December 15 and January Has No Coverage: The 2027 Open-… at a glance ✓ November 1, 2026 open enrollment starts. ✓ December 15, 2026 enroll by this day for January 1, 2027 coverage, and pay the… ✓ January 15, 2027 open enrollment ends. ✓ Before November 1 update 2027 income and household size, compare total yearly c… ✓ After January 15 only a Special Enrollment Period or Medicaid/CHI...
