Health insurance after moving to New Hampshire
Updated for plan year 2026
Run the numbers again, even if you just ran them in your old state. Premiums are set locally — by rating area, roughly your county — so the same insurer's same-tier plan can cost meaningfully more or less after a move, and the benchmark plan that your subsidy is measured against changes too. Same income, new address, different subsidy: in New Hampshire, the benchmark silver plan for a 40-year-old runs $450 a month before help, and what you personally pay depends on the math below, not the math you remember.
The deadline attached to the re-run: a move gives you 60 days after the moving date to enroll through HealthCare.gov — if you had qualifying coverage for at least one day in the 60 days before the move. That prior-coverage rule is the gatekeeper most pages mention last; here it's first, with its exceptions, in the next section. The estimator below prices your new county in about a minute, against the 46 plans New Hampshire lists from 4 insurers for 2026.
What you would actually pay in New Hampshire
Pre-filled with a New Hampshire 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 HealthCare.gov 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, New Hampshire'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 New Hampshire
New Hampshire uses the federal marketplace, HealthCare.gov — that is where you compare plans and enroll. For plan year 2026, 46 plans from 4 insurers are filed statewide.
New Hampshire 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 15, 2026. PY2027 window: shortened to Nov 1 - Dec 15, 2026 by the 2025 CMS Marketplace Integrity and Affordability final rule (previous standard window was Nov 1 - Jan 15). Coverage starts Jan 1, 2027.

A worked example
A single adult earning $39,100 a year — about 250% of the federal poverty level — would get an estimated subsidy of $175/month against the typical Silver benchmark in New Hampshire.

How to enroll in New Hampshire
- 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
Split the work into before-the-truck and after-the-boxes, and nothing falls through. Before: three protective moves. Keep your current coverage active — at least one day of qualifying coverage in the 60 days before the move is what opens the enrollment window after it, so an early cancellation can lock you out of the very thing you're counting on. Capture the paperwork while it's easy: a letter or bill from your insurer showing coverage and dates, because the marketplace may ask for it later. And note your move date precisely — the 60-day clock runs from it, not from when you feel settled.
After the move, week one or two: re-run the money. Premiums and benchmarks are set by rating area, so your subsidy in New Hampshire is a fresh calculation against your new county — statewide, benchmark silver sits at $450 for a 40-year-old — the estimator above handles it — and your income estimate should cover the whole calendar year across both states, job changes included; the result prices you against New Hampshire's market, not your old one. Then apply: through HealthCare.gov, which for arrivals from a different marketplace platform means a new application rather than a hand-off. Answer the move questions exactly; the application checks Medicaid eligibility automatically, which matters because Medicaid neither travels between states nor has an enrollment deadline.
Picking the plan deserves its own evening. Networks reset with the move, so search each finalist's directory for a primary care doctor and an urgent care near the new address; check drug lists if you take anything regularly; rank by twelve premiums plus the deductible you'd realistically touch. County menus differ enough — New Hampshire lists 46 plans from 4 insurers — that your old plan's brand may not exist here, and where it does, it may be priced and networked differently — judge it as a stranger.
Last, the follow-through that makes it stick: if the eligibility notice requests documents, send proof of the move (a lease, a utility bill, a change-of-address confirmation) and proof of the prior coverage by the notice's deadline — coverage can't be used until eligibility is confirmed and the first premium is paid. Then end the old plan as the new one starts, the first of the month after you pick. Two folders, two evenings, no gap.
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 New Hampshire, enrollment runs through HealthCare.gov. 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 15, 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 HealthCare.gov, 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 New Hampshire'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 15, 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 New Hampshire that's HealthCare.gov. 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 New Hampshire?
- New Hampshire uses HealthCare.gov. If you're arriving from another HealthCare.gov state, log into your existing account, report the move with your new address, and the application re-prices you for the new county — same login, updated plan menu. If you're arriving from a state that ran its own marketplace, your old account doesn't transfer: you'll create a HealthCare.gov account and complete a fresh application. Either way, the 60-day window covers the process, and your old plan needs an end date from its own marketplace.
Related guides
If you've read this far and the prior-coverage rule shut you out — you arrived without insurance and fit no exception — here is the honest playbook for the months ahead. Check Medicaid first: it has no enrollment window, New Hampshire's income rules may reach further than you expect, and the HealthCare.gov application checks for you. Watch for qualifying events that open their own windows: a new job's coverage starting and later ending, marriage, a baby. Meanwhile, community health centers bill on a sliding scale, which keeps routine care affordable while you wait. Then circle open enrollment — November 1, 2026 to December 15, 2026 — and treat it as non-negotiable, because it's the guaranteed door back in for next year's coverage. Set the reminder now, while the lesson stings. The rule that kept you out exists to stop people from buying coverage only after getting sick; it's reasonable policy and bad luck, and the system genuinely reopens every fall. Be standing at the door when it does — 46 plans from 4 insurers will be on the other side.
