ACA Health Insurance Open Enrollment 2027: November 1 Start, December 15 Deadline
The ACA Marketplace opens for 2027 coverage on November 1, 2026, with a December 15 deadline to enroll for January 1 coverage. Expats and newcomers without employer insurance must act during this annual window or face coverage gaps.
The Affordable Care Act (ACA) Marketplace open enrollment period for 2027 coverage has been confirmed after months of legal uncertainty. In most states, open enrollment runs from November 1, 2026, through January 15, 2027, though state-run marketplaces may have different schedules.
Key Enrollment Dates
- Open enrollment starts: November 1, 2026 (most states); October 15 in Idaho; October 23 in Connecticut and Massachusetts
- Deadline for January 1 coverage: December 15, 2026 (all states)
- Final enrollment deadline: January 15, 2027 (HealthCare.gov and most states); some state marketplaces extend to December 31
- Coverage start dates: January 1 if enrolled by December 15; February 1 if enrolled December 16–January 15
How to Enroll
Visit HealthCare.gov (federally operated) or your state's marketplace. You will need household income information, immigration status documentation, and details about any current coverage. Financial assistance (tax credits and cost-sharing reductions) is available if your household income is 100–400% of the federal poverty level.
What This Means for Foreigners
If you are a lawful permanent resident, asylee, refugee, or other eligible immigrant without employer-sponsored health coverage, open enrollment is your annual opportunity to select a plan. Missing the deadline means you cannot enroll unless you experience a qualifying life event (marriage, birth, job loss, loss of other coverage). Mark December 15 in your calendar—this is the critical deadline for coverage starting January 1, 2027. Review your state marketplace directly, as some (California, New York) have extended deadlines past December 15. Delaying enrollment risks coverage gaps and unexpected medical costs.
