Illinois Health Insurance Consumer Guide
Illinois runs a partnership exchange with the federal government. The state operates Get Covered Illinois, which has a website, in-person help, and a help desk.1 However, Illinois residents enroll in Affordable Care Act (ACA) Marketplace health plans through HealthCare.gov. Starting in 2026, Illinois will have its own state-run enrollment platform.
Use this guide to help you understand the Illinois Marketplace and choose the right health plan for you and your family. ACA Marketplace plans – or Obamacare or exchange – are affordable choices for many people. Enrolling on the exchange may make you eligible for financial assistance through an advance premium tax credit.

Frequently asked questions about health insurance in Illinois
Who can buy Marketplace health insurance?
You can buy a health plan through the exchange if:7
- You reside in the United States.
- You are a U.S. citizen or national.
- You are not incarcerated.
- You are not already covered by health insurance from a job, Medicare, Medicaid, Children’s Insurance Program (CHIP), or another approved health coverage provider.
Qualification for financial assistance, such as premium subsidies and cost-sharing reductions (CSR), depends on your income and how it compares with the cost of the second-lowest-cost Silver plan in your area. This can vary based on where you live and your age. Moreover, to be eligible for financial aid for your Marketplace plan, you must:
- Not have affordable health coverage available through your job. If your workplace provides insurance, but you find it too expensive, you can use our Employer Health Plan Affordability Calculator to see if you might be eligible for premium subsidies on the Marketplace.
- Not qualify for Medicaid or CHIP.
When can I enroll in an ACA-compliant plan in Illinois?
In Illinois, open enrollment for ACA Marketplace individual and family health coverage is from November 1 through January 15.8
You can sign up for an exchange plan or make coverage changes outside of open enrollment if you meet special enrollment period (SEP) requirements.9 This means you must have a qualifying life event, such as losing your health insurance, getting married, or having a baby.
If the open enrollment deadline passes and you don’t meet the SEP requirements, you can still sign up for an ACA plan. However, you must meet certain conditions, such as:
- If you’re eligible for premium tax credits and your income is not more than 150% of the poverty level, you can enroll anytime until at least 2025.10
- If you’re a Native American, you can enroll whenever necessary.11
For those who lose Medicaid or CHIP coverage between March 31, 2023 and July 31, 2024, an extended SEP allows you to enroll.12
How do I enroll in a Marketplace plan in Illinois?

How can I find affordable health insurance in Illinois?
Individuals and families have several options to find affordable health insurance coverage in Illinois:
- ACA Marketplace (HealthCare.gov): The ACA Marketplace is the only place where you can qualify for income-based subsidies known as Advance Premium Tax Credits (APTC) that help lower your monthly premiums. Nearly nine out of 10 Illinois exchange enrollees were eligible for subsidies on 2023 plans, saving $540 monthly with premium tax credits in Illinois. As a result, the average after-subsidy monthly premium was $147.13
- Cost-Sharing Reductions: You may qualify for cost-sharing reductions (CSR) if your income is below 250% of the federal poverty level.14 CSRs help reduce your out-of-pocket costs, making coverage more affordable.
- Medicaid: Illinois residents may qualify for affordable Medicaid coverage if eligible.
- Short-Term Health Insurance: For people who are not eligible for subsidies, Medicare, or Medicaid, short-term health insurance may offer a more budget-friendly option.
