Do you expect your household health insurance costs to increase in the coming year?
Individual health insurance open enrollment for Illinois residents will begin on November 1, 2026. Residents can secure coverage through the Get Covered Illinois marketplace or by working directly with insurance providers.
Why it matters
Understanding these enrollment dates is critical for residents to maintain continuous health coverage, as those ineligible for tax credits face rising premium costs. The market is also seeing constrained options, with only one provider available in some regions.
Enrollment windows for the 2027 plan year are tiered based on sign-up dates. While tax credits are available to offset rising costs, individuals without such subsidies will see premium increases.
