Health insurance after moving to Illinois
Updated for plan year 2026
An honest page has to start with the uncomfortable case: if you arrive in Illinois without recent coverage, the move itself probably doesn't let you enroll. The rule requires qualifying coverage for at least one day in the 60 days before a move — without it, and outside a few exceptions (arriving from abroad or a U.S. territory, tribal membership, living where no marketplace plan existed), the marketplace stays closed until open enrollment starts November 1, 2026. Your real options in the meantime: check Medicaid, which has no enrollment window and depends on income and Illinois's rules; watch for a different qualifying event — a job loss, marriage, a baby — that opens its own window; and lean on sliding-scale community health centers if neither applies.
If you did arrive insured — an employer plan, a marketplace plan, COBRA, or Medicaid all count — the door is open for 60 days from your move date. The rest of this page is for using it well: multiple plans from participating insurers on Get Covered Illinois, repriced for your new address.
What you would actually pay in Illinois
Pre-filled with a Illinois ZIP — change it to yours for exact results.
Here's how to use the rest of this page, depending on what the number above just told you. If the subsidized premium looks manageable, your remaining work is plan selection — read the cost and enrollment sections, then the mistakes list, and you can realistically finish on Get Covered Illinois within the hour. If the number looks high, the worked example and the deep-dive section explain the levers that actually move it: your income estimate, your household details, and in some cases the calendar itself. And if the number looks too good, trust it provisionally — then verify the income you entered, because optimistic estimates are the single most common source of tax-time regret in this system. The marketplace pays your subsidy in advance against the figure you give it, and the reconciliation at filing season is indifferent to good intentions. Whichever bucket you're in, Illinois's specifics are below: the actual market, the real prices, the deadlines that govern your situation, and answers to the questions people in your position ask most often. One habit serves all three buckets: write down the income figure you used today. When your situation changes — and it will — knowing exactly what the marketplace thinks you earn makes the update a two-minute correction instead of an archaeology project, and it keeps the advance subsidy honest all year.
The marketplace in Illinois
Illinois runs its own exchange, Get Covered Illinois — that is where you compare plans and enroll.
Illinois expanded Medicaid, so if your household income falls below about 138% of the federal poverty level you likely qualify for free or very low-cost coverage — check the state Medicaid office before buying a marketplace plan. The next open enrollment window runs from November 1, 2026 to December 31, 2026. This state has historically extended enrollment into January; under the 2025 federal rule (unstayed), PY2027 enrollment must end by Dec 31, 2026. Final dates not yet announced — based on the legal maximum.
A worked example
A single adult earning $39,100 a year — about 250% of the federal poverty level — would get an estimated subsidy of $371/month against the typical Silver benchmark in Illinois. Illinois runs its own exchange, so this is a state-average estimate — rougher than the figures for federal-marketplace states.
Your number depends on your actual income, household, and ZIP — run it above.
How to enroll in Illinois
- 01
Check your window
This qualifying event opens a special enrollment period: you have up to 60 days after it to pick a plan — there is no apply-ahead window. Miss it and you generally wait for the next open enrollment.
- 02
Gather your documents
If your Marketplace Eligibility Notice asks for documents, you must send two kinds: proof of the move and proof of prior coverage. Proof of move must show your name and the date of the move — e.g., bills or financial statements showing the new address or newly started services, a U.S. Postal Service change-of-address confirmation letter, a mortgage or rental/lease agreement for the new address, a letter from a government organization (Social Security, SNAP/TANF, DMV, IRS, LIHEAP, voter registration), or a homeowner's/renter's insurance letter showing the policy start date. You must also submit a document showing you had qualifying health coverage for at least 1 day in the 60 days before the move — a letter from an insurance company, employer (including COBRA coverage), or a government health program like Medicaid, CHIP, TRICARE, VA, or Peace Corps. If you moved from a U.S. territory or foreign country, you instead submit proof of that (official ID showing the territory, an I-94/I-94A arrival record, or a passport admission stamp). Upload or mail documents as soon as possible — if you don't submit them by the deadline, you won't have Marketplace coverage; a letter of explanation can be submitted if no listed documents are available.
- 03
Estimate your income honestly
Your subsidy is based on what you expect to earn this calendar year, not last year — estimating low means repaying the difference at tax time. Use the calculator above to see your number first.

Pick by total cost, not premium
The real annual cost is premium plus deductible, copays, and coinsurance — a cheaper-premium plan can cost more overall if you use care.
Your coverage start date is based on when you pick a plan, and you can't use coverage until your documents (if requested) confirm your eligibility and you pay the first premium. Under the federal effective-date rules (45 CFR 155.420(b)), a plan selected after the move takes effect the first day of the month following plan selection; if the plan is selected on or before the day of the move, coverage takes effect the first day of the month following the move.
What a move changes about your coverage, honestly
The rule that governs everything: to use a move as your way into Illinois's marketplace outside open enrollment, you must have had qualifying health coverage — an employer plan, a marketplace plan, Medicaid, COBRA, TRICARE, and similar all count — for at least one day during the 60 days before the move. Most pages mention this after the excitement; it deserves the lead, because it changes behavior before the move. Keep your old coverage running until you leave, even if you're tempted to cancel early and save a premium. That coverage is your ticket.
The exceptions are real but narrow. People moving to the U.S. from a foreign country or U.S. territory qualify without prior coverage. So do members of federally recognized tribes and ANCSA corporation shareholders. So does anyone who spent at least a day of the prior 60 living where no marketplace plan was available. And the definition of a qualifying move is broader than moving trucks: students moving to or from school, seasonal workers moving with the work, people leaving shelters or transitional housing. What never qualifies: a stay that's really a vacation, or relocating somewhere purely for medical treatment.
If the rule shuts you out, honesty about what's next: the marketplace generally stays closed to you until open enrollment, November 1, 2026 to December 31, 2026. The interim options are Medicaid — no enrollment window, income-based, worth checking in Illinois specifically since rules differ by state — another qualifying life event if one happens to you, and sliding-scale care at community health centers. It's a thin list; that's the point of leading with the rule.
If the rule lets you in, you get 60 days from the move date — all of them after it; there's no applying ahead of a move the way there is for a known coverage loss — to pick from multiple plans offered by participating insurers on Get Covered Illinois, where benchmark silver runs around $646 a month. Coverage starts the first of the month after you pick, the marketplace may ask for proof of both the move and the prior coverage, and the new county's prices and networks owe nothing to your old ones. The sections around this one handle each of those; none of them matter in Illinois or anywhere else unless the rule is satisfied first.
What to watch out for
The prior-coverage rule, before anything else
A move opens an enrollment window only if you had qualifying health coverage — an employer plan, a marketplace plan, Medicaid, COBRA, and similar — for at least one day during the 60 days before the move. This is the gatekeeper for everything else on this page, and it rewards planning: keep your old coverage running through the moving date rather than canceling early, and save a letter or bill that proves it. Arrive insured and you have 60 days to enroll; arrive uninsured and, outside a few exceptions, the move alone opens nothing.
The exceptions, if you arrive without coverage
Three groups can use the move-based window without prior coverage: people who moved to the U.S. from a foreign country or a U.S. territory; members of federally recognized tribes and Alaska Native (ANCSA) corporation shareholders; and people who lived somewhere no marketplace plan was available for at least a day of the prior 60 or during your most recent enrollment period. Qualifying moves also include students moving to or from school, seasonal workers moving with the work, and people leaving transitional housing. What doesn't qualify: vacation stays, or relocating somewhere solely for medical treatment.
Two kinds of proof, one folder
If your eligibility notice asks for documents, you'll need to show both halves: that you moved, and that you had coverage before it. For the move: a lease or mortgage, bills or financial statements showing the new address, a USPS change-of-address confirmation, or a letter from a government agency. For the coverage: a letter from an insurance company, employer, or program like Medicaid showing at least one day of coverage in the 60 days before the move. Arrivals from abroad or a U.S. territory substitute proof of that — a passport stamp or arrival record. Build the folder before the move scatters everything.
Your network doesn’t make the trip
Plan networks are contracts with local doctors and hospitals, and many plan types — HMOs and EPOs especially — cover routine care only inside them, with emergencies as the main exception. An out-of-state plan can leave you paying list price for every checkup near your new home while the premium keeps drafting. When you compare plans in the new county, open each finalist's provider directory and search for a primary care office and an urgent care near your actual address — and check the drug list while you're in there, because formularies reset along with networks.
Same name, different price
Premiums are set by rating area — roughly, your county — so a move changes prices even when nothing else changes: the same insurer's same-tier plan can cost meaningfully more or less at the new address. Your subsidy shifts too, because it's measured against the local benchmark plan, which changed when your county did. Same income, new address, different math, in either direction. Re-run the estimate against the new ZIP code before assuming anything from your old plan's pricing carries over — it usually doesn't, and the direction of the surprise is hard to guess.
A new marketplace can mean a new application
How you enroll depends on the marketplace your new state uses. Moving between two HealthCare.gov states means updating your existing application with the new address. Moving between marketplace systems — into or out of a state that runs its own portal — means starting fresh: new account, new application, income and household entered again. In Illinois, enrollment runs through Get Covered Illinois. Plan menus are county-level either way, so even an in-state move can change what's available. Budget an evening for the cross-system case, and tell your old marketplace when to end the old plan — it won't find out on its own.
Mistakes people make
Assuming your coverage moves with you
Health plans are sold, priced, and networked by location. A marketplace plan from your old state generally can't just continue in the new one, and even where an insurer operates in both, the plan, the network, and the price are different products. Treat a move as a re-purchase: new application, new comparison, new enrollment — inside the 60-day window the move opens. The people who skip this step usually discover it at the first doctor's visit, as an out-of-network bill.
Arriving uninsured without knowing the rule
The move-based enrollment window requires qualifying coverage for at least one day in the 60 days before the move. People drop their old plan early to save a premium, arrive uninsured, and learn they've disqualified themselves — the move alone opens nothing, and the wait runs to open enrollment unless an exception applies (arrival from abroad or a territory, tribal membership, or living where no plan was sold). The prevention costs one or two premiums: keep the old coverage through moving day.
Letting the move eat the 60-day window
60 days sounds generous until it competes with a lease, a job start, school registration, and furniture. The window runs from the move date and doesn't pause for any of it; week nine is too late no matter how good the excuse. Put the deadline on the calendar the week you arrive, and treat enrollment as one of the move's fixed tasks — an evening with the estimator and the plan listings settles it. Coverage also starts the first of the month after you pick, so early beats late by real weeks.
Keeping the out-of-state plan until things settle
It feels prudent — don't change everything at once — and it quietly converts your coverage into an emergency-only product. Routine care near the new home bills out-of-network under most plan types, often at full price with no out-of-pocket cap. Meanwhile the 60-day enrollment window is burning. Settle the insurance first, not last: enroll in a local plan, set the old one to end when the new one starts, and let everything else stay chaotic a little longer instead.
Not re-running the subsidy math in the new county
Your premium tax credit is the gap between the local benchmark plan and your expected income contribution — and 'local' changed. Movers who assume last year's subsidy carry the old number into the new budget and get surprised in either direction: a cheaper rating area can shrink the credit, a pricier one can grow it. The fix takes a minute: re-run the estimate with the new ZIP code, and while you're in the application, update the income figure for any job change that came with the move.
Frequently asked questions
What if I missed the 60-day deadline?
- You generally wait for open enrollment, which runs November 1, 2026 to December 31, 2026 for coverage starting next year. The exceptions are other qualifying life events — getting married, having a baby, moving to a new coverage area, or losing other qualifying coverage — each of which opens its own enrollment window. In the meantime, check whether you qualify for Medicaid, which has no enrollment deadline, and know that any care you get while uninsured is billed at full price.
Do I lose my health insurance if I move to another state?
- A marketplace plan doesn't follow you across state lines — plans are sold and networked by state and county, so moving means ending the old plan and enrolling in a new one where you live. The move itself opens a 60-day enrollment window, provided you had qualifying coverage at least one day in the 60 days before the move. Employer coverage that continues at the new location, and plans with multi-state networks, are the exceptions worth confirming with the plan directly.
I just moved — can I enroll in a health plan now?
- Yes, if you had qualifying health coverage for at least one day during the 60 days before your move — that's the rule most people learn too late. Qualifying coverage includes an employer plan, a marketplace plan, Medicaid, CHIP, COBRA, and similar. If you clear it (or fit an exception, like arriving from abroad), you have 60 days from the move date to pick a plan through Get Covered Illinois, with coverage starting the first of the month after you choose.
What counts as coverage before my move?
- Qualifying health coverage for at least one day in the 60 days before the move: a job-based plan (yours or a family member's), a marketplace plan, Medicaid, CHIP, TRICARE, VA coverage, or COBRA continuation coverage all count. Proof, if requested, is a letter from the insurer, employer, or program showing coverage during that window. If you moved from a foreign country or U.S. territory, you don't need prior coverage — proof of where you lived takes its place.
What if I moved without having insurance?
- Then the move alone generally doesn't open an enrollment window — that's the honest answer, and the exceptions are narrow: you arrived from a foreign country or U.S. territory, you're a member of a federally recognized tribe or an ANCSA corporation shareholder, or you lived somewhere no marketplace plan was available. Otherwise: check Medicaid, which has no enrollment deadline and depends on Illinois's income rules; watch for other qualifying events like a job's coverage starting then ending, marriage, or a birth; and mark open enrollment, November 1, 2026 to December 31, 2026.
How long after moving do I have to enroll?
- 60 days, counted from the date of the move — and the window runs only after it. Unlike a known coverage loss, a planned move generally can't be used to enroll ahead of time, so plan on doing the work once you've arrived. Coverage starts the first of the month after you pick a plan, which makes the first weeks the valuable ones: enrolling early can move your start date up a full month compared with enrolling near the deadline. Miss the window and you generally wait for open enrollment.
Can I keep my marketplace plan in my new state?
- No — marketplace plans are specific to the state and county where they're sold. After a move you enroll through the new state's marketplace; in Illinois that's Get Covered Illinois. If both states use the federal platform, you update your existing application with the new address and pick from the new county's plans; if either state runs its own marketplace, expect to create a new account and apply fresh. Either way, tell your old marketplace when to end the old plan so it doesn't bill past your move.
Does moving within the same state count?
- It can. The qualifying event is moving to a new home in a new ZIP code or county — crossing a state line isn't required, because plan menus and prices change at the county level. The same conditions apply: qualifying coverage for at least one day in the 60 days before the move, and 60 days after it to act. Moving within the same ZIP code generally doesn't qualify; in that case just update your address with your insurer and the marketplace.
What documents do I need after a move?
- Two kinds, if your eligibility notice asks for them. Proof of the move, showing your name and the date: a lease or mortgage, bills or bank statements at the new address, a USPS change-of-address confirmation, or a letter from a government agency. And proof of prior coverage: a letter from an insurance company, employer, or a program like Medicaid showing at least one day of coverage in the 60 days before the move. Submit by the notice's deadline — coverage can't be used until eligibility is confirmed and the first premium is paid.
Does COBRA count as coverage before a move?
- Yes. COBRA continuation coverage is qualifying coverage for the move rule — the marketplace's own list of acceptable proof documents includes letters showing employer coverage including COBRA. So if you kept COBRA running after a job ended and then moved, you meet the prior-coverage requirement, and the move opens a 60-day window to switch into a marketplace plan in your new state. That switch is often a money-saver, since COBRA bills the full premium and marketplace plans price against your income.
Why is the same insurer's plan a different price after my move?
- Because premiums are set by location. Insurers price plans by rating area — groups of counties — to reflect local medical costs and competition, so an identical-looking plan carries a different premium at your new address. Your subsidy changes too: it's measured against the local benchmark plan, which changed along with your county. The result can move your bottom line in either direction even with the same income, which is why re-running the numbers in the new county is step one, not a formality.
Do I need a new application in Illinois?
- Probably yes. Illinois runs its own marketplace, Get Covered Illinois, and accounts don't transfer between marketplace systems — an application from HealthCare.gov or another state's portal doesn't follow you. Plan to create an account with Get Covered Illinois and enter your application fresh: income, household, the new address. The subsidies are the same federal premium tax credit you had before; only the paperwork starts over. Don't forget the other half: ask your old marketplace to end your old plan as the new one starts.

The quiet money mistake after a move is keeping last year's subsidy math. Your premium tax credit is the gap between a local benchmark plan's price and your expected contribution — and the benchmark changed when your county did. Same income, new rating area, different credit: sometimes larger, sometimes smaller, rarely identical. In Illinois the benchmark silver plan runs around $646 a month for a 40-year-old before help; what that means for you personally is exactly what the estimator above computes from your new ZIP code, across the multiple plans Illinois actually sells. While you're updating the address, update the income too — moves cluster around job changes, and the marketplace wants your expected total for the whole calendar year, both states' earnings included. An estimate that drifted through the move gets reconciled on your tax return; five minutes on Get Covered Illinois keeps the advance credit honest. Then enroll inside the 60-day window, and let the new county's math — not the old one's, and not the old plan's reputation — pick the plan.
