Who is uninsured in Connecticut
200,524 people under 65 in Connecticut have no health coverage — 7.0% of the under-65 population, 37th highest of the 51 states and DC. Of those, 95,936 earn inside the premium tax credit range — 48% of the state's uninsured.
53,800 uninsured Connecticut residents (27% of the total) earn under $22,025. Connecticut expanded Medicaid, so that group mostly qualifies for it instead — and it enrolls year-round.
Where Connecticut residents enroll, and by when
Connecticut does not use HealthCare.gov. It runs Access Health CT at accesshealthct.com, and sets its own enrollment dates — which are not always the federal ones. Applying at HealthCare.gov will redirect you.
Open Enrollment for Connecticut: October 23, 2026 to January 15, 2027.
Checked 2026-09-01. 2027 dates moved nationally after a court ruling — what changed and why.
