Illinois operates its own state-based health insurance marketplace, Get Covered Illinois (GetCoveredIllinois.gov), which launched in 2024 replacing Healthcare.gov for Illinois residents. Illinois expanded Medicaid under the ACA, covering adults up to 138% of the Federal Poverty Level ($20,783 for a single person). For those above 138% FPL, marketplace plans are available with ACA premium subsidies. Average premiums for a 40-year-old Silver plan in Illinois are roughly $480/month before subsidies. Illinois also prohibits tobacco surcharges on marketplace plans — one of only a handful of states to do so. Our calculator estimates your premium, Medicaid eligibility, subsidy amounts, and out-of-pocket costs based on income, age, and household size.

Over 3.5 million Illinoisans are enrolled in Medicaid/CHIP.
What is Get Covered Illinois?
Get Covered Illinois is the state's own health insurance marketplace (state-based exchange) that launched for the 2024 plan year. It replaced Healthcare.gov for Illinois residents, giving the state more control over enrollment, outreach, and consumer assistance. Enrollment works the same way — shop Bronze/Silver/Gold plans, check subsidy eligibility, and enroll online at GetCoveredIllinois.gov.
When is open enrollment in Illinois?
Open enrollment for Get Covered Illinois marketplace plans typically runs November 1 through January 15. You can enroll outside this window only with a qualifying life event (QLE) such as job loss, marriage, birth of a child, or moving to Illinois. Medicaid enrollment is available year-round with no open enrollment period — apply anytime through ABE (Application for Benefits Eligibility).
Are ACA subsidies available in Illinois?
Yes — if your household income is above 138% FPL (below that you qualify for Medicaid) and up to 400% FPL, you qualify for premium tax credits. Enhanced subsidies (extended through 2025) cap premiums at 8.5% of income for households above 400% FPL. A single person earning $40,000 might receive $200-350/month in subsidies, bringing a Silver plan to $100-250/month.
