Quick answer
Federal Marketplace Open Enrollment for 2026 coverage ended January 15, 2026. As of July 27, 2026, most people need a Special Enrollment Period to enroll in or change a Marketplace plan. Medicaid and CHIP applications remain open year-round, and state-run Marketplaces can use different dates.
Key takeaways
- Do not treat the expired January 15 deadline as a current call to enroll.
- A qualifying life event can open a time-limited Special Enrollment Period.
- Coverage does not start until required enrollment steps and the first premium are completed.

What can you do now?
- Use HealthCare.gov to check whether a recent loss of coverage, move, marriage, birth, adoption, or other qualifying event opens a Special Enrollment Period.
- Check Medicaid and CHIP eligibility; applications are accepted year-round.
- If your state runs its own Marketplace, follow that exchange’s current dates and documentation rules.
Special Enrollment Period timing matters
HealthCare.gov explains that some qualifying events allow enrollment for a limited period before or after the event, often 60 days. The event, documentation, and coverage start date vary, so use the official eligibility flow rather than assuming a date.
Before selecting a plan
- Update expected 2026 household income and household members.
- Compare premiums, deductibles, out-of-pocket limits, provider networks, and drug coverage.
- Read notices about advance premium tax credits and report income changes promptly.
- Pay the first premium to the insurance company by its deadline.
