1. What actually changed
Until now, being “lawfully present” was enough for two separate things: it let you buy a plan through the Marketplace, and it let you qualify for the premium tax credit that brings the monthly cost down. From plan year 2027 those two tests come apart. Lawful presence still decides whether you can enroll. A narrower test now decides whether you get help paying.
CMS set this out in guidance released on October 5, 2026, implementing section 71301 of Public Law 119-21. From plan year 2027, advance payments of the premium tax credit and income-based cost-sharing reductions are allowed only for U.S. citizens, U.S. nationals and “eligible noncitizens”. The underlying change is effective for taxable years beginning after December 31, 2026, which is why it lands on the 2027 plan year and not this one.12
2. The three statuses that keep it
“Eligible noncitizen” sounds like a broad description and is not one. It is a defined term, and it is a subset of lawfully present rather than a synonym for it. It covers exactly three groups:13
- Lawful Permanent Residents — green card holders.
- Cuban or Haitian Entrants.
- Individuals lawfully residing under a Compact of Free Association — migrants from the Marshall Islands, Micronesia and Palau.
If you are in one of those three, your eligibility for financial help is unchanged. That is worth saying plainly in this county, because the category that is being quietly preserved is the one that covers a large share of the households who have been calling us frightened. Being a Cuban or Haitian Entrant does not put you outside the new rule. It puts you inside the group the rule protects.
3. Who can still enroll, but pays full price
The people genuinely affected are lawfully present noncitizens who do not fall into those three categories. For them the rule is specific and limited: they remain eligible to enroll in a qualified health plan through the Marketplace if they otherwise qualify, but no premium tax credit and no cost-sharing reductions are allowed for their coverage. In plain terms, the door is still open and the discount is gone.1
That distinction matters because of how people react to bad news. Someone who believes they have lost coverage altogether tends to walk away from the Marketplace entirely. Someone who understands they have lost the subsidy can still shop, still compare a Bronze plan against a Silver one, and still make a decision with real numbers in front of them. CMS wrote the implementing regulation into the 2027 Notice of Benefit and Payment Parameters, and nothing in it removes the right to buy.5
There are now two different tests, not one
Lawful presence decides whether you may buy a Marketplace plan. Eligible noncitizen status decides whether you get help paying for it. From plan year 2027 it is possible to pass the first test and fail the second — and that is the case this rule creates.
4. The December 15 deadline
Open Enrollment for 2027 coverage runs from November 1, 2026 to January 15, 2027 on HealthCare.gov. December 15, 2026 is the last day to enroll or change plans for coverage that starts January 1; people who enroll between December 16 and January 15 start on February 1 instead. Those dates are the familiar ones and they have not moved.4
What is new is that December 15 now carries a second job. CMS ties the redetermination of noncitizen enrollees to “the last day on which a plan selection may be made for coverage effective January 1” — December 15. Return to the Marketplace and update your application with your current immigration document before that date and you are assessed on what you actually are. Let it pass and you are assessed on whatever the government can confirm electronically without your help.1
December 15, not January 15
January 15 is when Open Enrollment closes. December 15 is the day that decides whether you are renewed with financial help or without it. Most reminder emails mention only the first one.
5. If they cannot verify you: the 95 days
Here is the sequence if you do nothing. If the Marketplace already holds verified data from the Department of Homeland Security showing you are an eligible noncitizen, you stay eligible and are renewed normally. If it can newly verify you, same outcome. If it has neither — no prior verification and no successful check now — you are redetermined ineligible for financial help effective January 1, 2027, and generally re-enrolled into a plan without the credit and without cost-sharing reductions. Separately, if the check shows you are no longer lawfully present, Marketplace coverage itself ends on January 1.1
If you do apply and the electronic check fails, you are not simply refused. You receive a data matching issue and 95 calendar days to send documents, and during those 95 days you keep the premium tax credit and cost-sharing reductions if you are otherwise eligible. Documents that CMS names as examples include a Permanent Resident Card, an Employment Authorization Document and an Arrival/Departure Record I-94 or I-94A. The system is built to give you time — but only if you are in it.7
6. The dates, in one table
Four dates decide almost everything here, and only one of them is widely known. This is the whole calendar in one place:
| Date | What happens | What it means for you |
|---|---|---|
| November 1, 2026 | Open Enrollment opens for 2027 coverage | The application now asks whether you have eligible noncitizen status |
| December 15, 2026 | Last day to pick a plan for January 1 coverage | Also the cut-off that decides how a noncitizen enrollee is redetermined |
| January 1, 2027 | New eligibility rule takes effect | Anyone not verified as an eligible noncitizen loses financial help from this date |
| January 15, 2027 | Open Enrollment closes | Enrol December 16 to January 15 and coverage starts February 1 |
| 95 days from a failed check | Data matching issue deadline | Send documents; you keep the credit while the clock runs |
Read the middle row twice. December 15 is doing two different jobs this year, and the second one is not printed on the reminder emails most people get.14
Open Enrollment runs November 1 to January 15
Not sure which category you are in? That is the fifteen-minute version of this conversation.
7. The grace period that is gone
There is a provision in the federal rules giving people who fall behind on premiums a three-month grace period before coverage is terminated. It is a genuine protection and a lot of households have quietly relied on it. It applies only to enrollees who were receiving the premium tax credit at the point they entered delinquency.6
So someone auto-re-enrolled without the credit is, by definition, outside it. CMS says these enrollees instead get whatever grace period the insurance company sets, subject to state law. The practical effect compounds the first problem: the household is now paying a much larger premium than last year, and the cushion that used to absorb one missed month is no longer there.1
8. Mixed-status households and Form 1095-A
Households where some members are citizens and others are not do not collapse under this rule. Each person is assessed on their own status, so the citizens and the eligible noncitizens in a household keep their own eligibility for financial help regardless of who else is on the application.1
- The household stays on one application. Nothing in this rule requires a mixed-status household to split itself into separate applications.
- Each person is assessed on their own status. A citizen child and a Lawful Permanent Resident parent keep their own eligibility for financial help whatever the status of anyone else on the form.
- The share belonging to members who are not eligible noncitizens is separated out. CMS describes this on Form 1095-A: the enrollment premium and benchmark plan amounts may be reduced to exclude that portion.
Expect the tax paperwork to look different. All lawfully present enrollees, including eligible noncitizens, will receive Form 1095-A from January 2028 for the 2027 tax year. Enrollees who are lawfully present but not eligible noncitizens may see blank or zero entries in Part III. In a mixed-status household, the monthly enrollment premium and benchmark plan amounts may be reduced to exclude the portion belonging to members who are not eligible noncitizens. That is the form working correctly, not a mistake — though if something genuinely looks wrong, the Marketplace will issue a corrected one.9
9. What this does not touch
This rule is about Marketplace financial help and nothing else. CMS states directly that section 71301 does not apply to Medicaid or the Children’s Health Insurance Program. If your children are covered through Florida KidCare, or someone in the household is on Medicaid, this particular change does not reach them.1
A different section of the same law does affect federal funding for coverage provided to certain noncitizens under Medicaid and CHIP, which is a real question but a separate one. Treat any advice that merges the two with suspicion: they have different rules, different timelines and different paperwork, and conflating them is the fastest way to talk someone out of coverage they are still entitled to.1
Do not cancel one program because of a change to another
If your children are covered through Florida KidCare, or someone in the household is on Medicaid, this Marketplace rule does not change that coverage. Check each program on its own terms before you drop anything.
10. Why Florida has no cushion
One detail in the guidance matters more in Florida than almost anywhere. CMS wrote it for the Federally-facilitated Exchange and says explicitly that it does not address State-Based Marketplaces running their own platform. Some states run their own exchange and are making their own arrangements. Florida does not. Florida uses HealthCare.gov, so this applies here in full, immediately, with no state layer to soften it.1
The second thing is linguistic rather than legal. The application now asks you to attest to whether you hold eligible noncitizen status, and that question will be answered by people reading it in a second or third language, often quickly, often on a phone. The difference between “lawfully present” and “eligible noncitizen” is not obvious in English and it is less obvious in translation. Getting that attestation wrong is how a person who qualifies ends up paying full price.4
11. What to do this week
Five things, in order, and none of them take long:8
- Find your immigration document now, before November 1 — the green card, the Employment Authorization Document, or the I-94. You will need the numbers from it, not just the fact that you have it.
- Work out which of the three categories you are in, if any. Lawful Permanent Resident, Cuban or Haitian Entrant, or COFA migrant means your eligibility is unchanged.
- Return to the Marketplace and update your application before December 15, even if nothing about your situation has changed. This is the single action that prevents a silent redetermination.
- Open the mail from the Marketplace. If your status could not be verified, the notice will say so, and the 95-day clock starts whether or not you read it.
- If you are losing the credit, price the plan anyway before you drop it. Full price on a Bronze plan is not the same number as full price on the Silver plan you were auto-renewed into.
12. Frequently asked questions
Do immigrants lose ACA subsidies in 2027?
Not all of them, and the blanket version of that sentence is doing real harm locally. From plan year 2027 Marketplace financial help is allowed for U.S. citizens, U.S. nationals and what CMS calls “eligible noncitizens”, which means exactly three groups: Lawful Permanent Residents, Cuban or Haitian Entrants, and people lawfully residing under a Compact of Free Association. If you are in one of those three, nothing about your eligibility has changed. If you are lawfully present but in a different category, you can still enroll in a Marketplace plan — you just pay full price for it.
I am a Cuban or Haitian Entrant. Am I affected?
Your eligibility for the premium tax credit is not affected. Cuban or Haitian Entrant is written into the rule as one of the three statuses that keep it. What can still affect you is verification: if the Marketplace cannot confirm your status electronically through the Department of Homeland Security, you can be moved to full price on January 1 even though you qualify. That is a paperwork problem, not an eligibility problem, and it is fixable — but only if you act.
What happens if I do nothing during Open Enrollment?
It depends on what the Marketplace already knows about you. If it has already verified your eligible noncitizen status through DHS SAVE, or can verify it now, you stay eligible and are renewed normally. If it has neither, you are redetermined ineligible for financial help effective January 1, 2027, and generally auto-re-enrolled into a plan with no premium tax credit and no cost-sharing reductions. You would find out when the first full-price bill arrives.
What is the exact deadline?
CMS ties the redetermination to “the last day on which a plan selection may be made for coverage effective January 1”. On HealthCare.gov that is December 15, 2026. Open Enrollment itself runs from November 1, 2026 to January 15, 2027, but December 15 is the date that governs whether you are renewed with or without financial help.
The Marketplace says it cannot verify my status. What now?
You get what is called a data matching issue, and you have 95 calendar days to send documents. The important part: during those 95 days you keep the premium tax credit and cost-sharing reductions if you are otherwise eligible, so your coverage does not lurch to full price while you sort it out. Documents CMS names include a Permanent Resident Card, an Employment Authorization Document, or an Arrival/Departure Record I-94 or I-94A.
Can I still buy a Marketplace plan if I am not an eligible noncitizen?
Yes, provided you are lawfully present. The rule changed who can get financial help, not who can enroll. You remain eligible to buy a qualified health plan through the Marketplace if you otherwise qualify; the credit and the cost-sharing reductions are what you lose. For many households that is a very large difference in monthly cost, which is why it is worth pricing before you decide.
I have heard there is no longer a grace period. Is that right?
For this group, yes, and it catches people. The three-month grace period in the federal rules applies only to enrollees who were receiving the premium tax credit when they fell behind on premiums. Someone re-enrolled without the credit is not in that category, so they get only whatever grace period the insurance company sets, subject to state law. A missed payment ends coverage faster than it used to.
What about my household where some of us are citizens and some are not?
Mixed-status households keep working, and this is the part worth being precise about. The members who are citizens or eligible noncitizens keep their own eligibility. On Form 1095-A, the enrollment premium and benchmark plan amounts may be reduced to leave out the share belonging to household members who are lawfully present but not eligible noncitizens. Expect the form to look different from last year and do not assume it is an error.
Does this change Medicaid or Florida KidCare?
No. CMS states plainly that this section applies to Marketplace financial help and not to Medicaid or the Children’s Health Insurance Program. A separate section of the same law affects federal funding for certain noncitizens in those programs, which is a different question from the one this article answers.
Who can I talk to about this in Broward or Miami-Dade?
You can call the Marketplace directly on 1-800-318-2596, 24 hours a day, or TTY 1-855-889-4325. If you would rather sit with someone who speaks Creole, French or Spanish, read the notice with you and work out which of the three categories you are in before you touch the application, that is what we do, and there is no charge for it.
