Health insurance after moving to Washington
Updated for plan year 2026
The costliest assumption in a move is that health insurance comes along like furniture. It mostly doesn't. Plan networks are built around local doctors and hospitals — many plans cover little or nothing out of network except emergencies — so a plan from your old state can leave you effectively uncovered in your new one even while you keep paying for it. And plans are priced and sold by location: cross a state or even a county line and the menu changes, the prices change, and your old plan may simply not exist here.
What you get instead is a fresh start with a deadline: a move qualifies you for a 60-day enrollment window in Washington — provided you had qualifying coverage for at least one day in the 60 days before the move, a requirement this page treats as headline news rather than fine print. Below: the rule and its exceptions, what multiple plans from participating insurers cost at your income through Washington Healthplanfinder, and the handoff that avoids a gap between the old plan and the new one.
What you would actually pay in Washington
Pre-filled with a Washington ZIP — change it to yours for exact results.
The estimate is most fragile at the edges, so check whether you're near one. At the low end sits Medicaid: if your household income falls under that line, marketplace subsidies generally aren't the path — the program itself is, with no premium for most people and no enrollment deadline at all. At the high end, the help phases out: in 2026 the premium tax credit stops above 400% of the federal poverty level, so an estimate that drifts over the line takes the entire subsidy with it, not a sliver of it. Between those edges the math is smooth and forgiving — a thousand dollars of income moves the subsidy modestly. Near them, it isn't. If the income you entered sits close to either threshold, this is the moment to firm it up: check what you've actually earned year-to-date and make a sober guess about the rest before you lean on the result. The Washington sections below treat both edges honestly — including what to do if your income lands below the marketplace's reach, where the answer depends on decisions Washington has made about Medicaid. And treat the 400% line with particular respect if you're anywhere near it: a year-end bonus, a capital gain, or an unexpectedly strong fourth quarter can push a household over after months of subsidies were already paid out — all of which get reconciled on the return. Near that edge, a conservative income estimate is the financially cautious one, the opposite of the usual advice.
The marketplace in Washington
Washington runs its own exchange, Washington Healthplanfinder — that is where you compare plans and enroll.
Washington 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. PY2027 window announced by Washington Healthplanfinder: Nov 1 - Dec 31, 2026 (shortened from the prior Nov 1 - Jan 15 window by federal rule).
A worked example
A single adult earning $39,100 a year — about 250% of the federal poverty level — would get an estimated subsidy of $337/month against the typical Silver benchmark in Washington. Washington 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 Washington
- 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
Take the failure case seriously, because it's common: you arrive in Washington uninsured — coverage lapsed before the move, or there was never any — and you assume the move itself gets you in. It doesn't. The move-based special enrollment period requires qualifying coverage for at least one day during the 60 days before the move. No coverage, no window — unless you fit one of the narrow exceptions: you moved 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 with no marketplace plan available for at least a day of those 60 days or during your last enrollment period.
What the months until open enrollment actually look like, honestly. Medicaid is the first stop: it has no enrollment window, it's run state by state — so Washington's income rules apply, not your old state's, and old-state Medicaid generally won't pay for care here — and the Washington Healthplanfinder application screens you for it automatically. Children often qualify for Medicaid or CHIP at household incomes well above the adult cutoffs, so check the kids even if the adults miss. Beyond that: a different qualifying life event — starting a job with coverage and later losing it, marriage, a birth — opens its own window whenever it happens; community health centers charge on sliding scales; and open enrollment, November 1, 2026 to December 31, 2026, is the guaranteed reentry for next year's coverage.
Now the prevention, for anyone reading before the truck arrives. Keep your old plan through the move even if it feels wasteful — one extra premium is the cheapest insurance against months uninsured in a state whose benchmark runs around $612 a month. COBRA counts as qualifying coverage, so continuing an employer plan you'd otherwise drop preserves the window too. And once you land, move fast: the window runs 60 days from the move date, coverage starts the first of the month after you pick from Washington's multiple plans, and the marketplace may ask for proof of both the move and the coverage that preceded it. The rule rewards people who arrive insured; arrange to be one of them.
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 Washington, enrollment runs through Washington Healthplanfinder. 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 Washington Healthplanfinder, 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 Washington'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 Washington that's Washington Healthplanfinder. 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 Washington?
- Probably yes. Washington runs its own marketplace, Washington Healthplanfinder, 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 Washington Healthplanfinder 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 Washington the benchmark silver plan runs around $612 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 Washington 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 Washington Healthplanfinder 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.
