Obamacare 2027: Open Enrollment Dates, APTC & Immigration ChangesDo you need health coverage for 2027, or do you currently have a Health Insurance Marketplace plan that needs to be renewed?
The 2027 Health Insurance Marketplace Open Enrollment Period begins November 1, 2026, and ends January 15, 2027 for states that use HealthCare.gov. During this period, eligible consumers can apply for coverage, renew their current coverage, or select a different health plan.
For 2027, it is especially important to review your situation before renewing.
There are important changes involving:
- Eligibility for premium tax credits and other Marketplace savings.
- Immigration statuses that may qualify for Marketplace savings.
- Eligibility verification requirements.
- Special Enrollment Periods.
- Health plans, premiums, benefits, and provider networks available for 2027.
Do not assume that your 2026 coverage, premium, or financial assistance will remain the same in 2027.
Your final eligibility and costs are determined using the information provided in your Marketplace application. HealthCare.gov explains that prices shown before completing an application are estimates; your exact prices are available after providing the required information.
Key 2027 Open Enrollment Dates
For states using HealthCare.gov, these are the key dates currently published:
| Action | Date | Coverage start date |
|---|---|---|
| Open Enrollment begins | November 1, 2026 | – |
| Enroll by this date | December 15, 2026 | January 1, 2027 |
| Final Open Enrollment deadline | January 15, 2027 | February 1, 2027 |
| Coverage starts if you enroll by December 15, 2026 | January 1, 2027 | January 1, 2027 |
| Coverage starts if you enroll from December 16, 2026 through January 15, 2027 | February 1, 2027 | February 1, 2027 |
These dates apply to HealthCare.gov. State-based Marketplaces may have different deadlines, procedures, or enrollment periods.
After January 15, you generally need to qualify for a Special Enrollment Period (SEP) to enroll in or change Marketplace coverage. Medicaid and CHIP accept applications throughout the year.
How Does Open Enrollment Work?
If you already have Marketplace coverage, do not simply assume that your current plan will remain the same.
When preparing your 2027 application, update any changes you expect during the upcoming year.
Information you should review includes:
- Expected annual household income.
- Household size.
- Address.
- Marital status.
- Immigration information, when applicable.
- Access to health coverage through an employer or another program.
- Changes in employment or self-employment.
- Household members who need coverage.
The Marketplace uses information about your household, income, and access to other coverage when determining potential eligibility for the Premium Tax Credit and advance payments of that credit.
Use Your Expected 2027 Income
Do not automatically use your 2026 income if you expect to earn a different amount in 2027.
This can be especially important for self-employed individuals, small-business owners, commission-based workers, and families whose income may fluctuate throughout the year.
If your circumstances change after enrollment, update your Marketplace information.
Important Changes to Financial Assistance for 2027
One of the most significant issues for 2027 involves the Premium Tax Credit (PTC) and the Advance Premium Tax Credit (APTC).
The PTC is a federal tax credit that may help eligible consumers pay premiums for coverage purchased through the Marketplace.
APTC allows eligible consumers to use some or all of their estimated tax credit in advance. The Marketplace sends the advance payment directly to the insurance company, reducing the consumer’s monthly premium.
The General 400% Federal Poverty Level Limit Returns
The temporary expansion of the Premium Tax Credit removed the upper 400% Federal Poverty Level (FPL) income limit for tax years 2021 through 2025.
That temporary expansion has ended.
For 2027, the general PTC rule once again requires household income of at least 100% but no more than 400% of the Federal Poverty Level, in addition to meeting the other eligibility requirements. The IRS recognizes limited exceptions involving income below 100% FPL.
This means that receiving APTC in a previous year does not guarantee that you will receive the same financial assistance in 2027.
Consumers within the 100%–400% FPL range also will not necessarily receive the same amount of assistance.
Other eligibility requirements matter as well, including access to certain employer-sponsored coverage or government health programs.
Could Health Insurance Premiums Increase in 2027?
The amount a consumer ultimately pays can change for several reasons, including:
- County of residence.
- Age.
- Insurance company.
- Health plan selected.
- Household size.
- Expected annual household income.
- Household members requesting coverage.
- Eligibility for financial assistance.
- Prices of the plans available in the area.
For that reason, do not calculate your 2027 premium based only on a general percentage increase reported in the news or on social media.
HealthCare.gov allows consumers to preview estimated prices, but exact pricing is determined after completing an application with the necessary household information.
Important Immigration Changes for 2027
This is one of the most important changes for the 2027 coverage year.
Beginning January 1, 2027, not every immigration status that may qualify someone for Marketplace coverage will also qualify that person for federal Marketplace savings.
HealthCare.gov currently identifies three non-citizen categories that may qualify for Marketplace savings beginning January 1, 2027:
- Lawful Permanent Resident (LPR) — commonly referred to as a Green Card holder.
- Cuban or Haitian Entrant.
- Compact of Free Association (COFA) migrant.
Marketplace savings can include the Premium Tax Credit/APTC and, when applicable, cost-sharing reductions.
Marketplace Coverage and Marketplace Savings Are Not the Same Thing
This distinction is extremely important for 2027:
A person may have an immigration status that allows them to obtain Marketplace coverage while not having an immigration status that qualifies them for federal Marketplace savings.
HealthCare.gov specifically explains this distinction for 2027.
Immigration Status: Marketplace Coverage vs. Savings in 2027
The following is a general guide based on information currently published by HealthCare.gov. Individual eligibility must be determined through the Marketplace application.
| Immigration Status / Category | May Be Eligible for Marketplace Coverage | May Qualify for Federal Marketplace Savings in 2027* |
|---|---|---|
| Lawful Permanent Resident / Green Card | ✓ | ✓ |
| Cuban or Haitian Entrant | ✓ | ✓ |
| COFA Migrant | ✓ | ✓ |
| Asylee | ✓ | — |
| Refugee | ✓ | — |
| Temporary Protected Status (TPS) | ✓ | — |
| Certain Employment Authorization Document (EAD) holders | ✓ | — |
| Certain individuals granted parole | ✓ | — |
| Valid employment visa | ✓ | — |
| Valid student visa | ✓ | — |
| U Visa | ✓ | — |
| T Visa | ✓ | — |
| Other lawfully present statuses recognized by the Marketplace | May qualify | — |
*This column refers specifically to federal Marketplace savings for non-citizens beginning January 1, 2027. Additional eligibility requirements apply. HealthCare.gov provides the complete list of immigration statuses that may qualify for Marketplace coverage.
Therefore, having a work permit by itself does not mean a person will qualify for APTC in 2027.
Likewise, receiving APTC in 2026 does not guarantee APTC eligibility in 2027.
What About DACA?
HealthCare.gov maintains specific information regarding DACA and Marketplace eligibility.
Because DACA Marketplace eligibility has been affected by regulatory and court actions, consumers should verify the current HealthCare.gov guidance when applying rather than relying on information from previous coverage years.
Mixed Immigration Status Families
A household may include family members with different citizenship or immigration statuses.
For example, one household might include U.S. citizens, lawful permanent residents, and family members with other immigration classifications.
Eligibility should be evaluated for each person applying for coverage, together with the household information required by the Marketplace.
If one household member is not eligible for certain coverage or financial assistance, that does not automatically mean other eligible household members cannot receive coverage or assistance.
HealthCare.gov also explains that family members who are not applying for coverage generally do not have to provide information about their citizenship or immigration status.
What If Household Income Is Below 100% FPL?
This area requires special care.
The general Premium Tax Credit rule includes an income requirement of at least 100% of the Federal Poverty Level, but the IRS recognizes limited exceptions for certain circumstances involving household income below 100% FPL.
Therefore:
Do not determine that someone qualifies or does not qualify for APTC based solely on projected income below 100% FPL.
The determination may require consideration of:
- Expected annual household income.
- Tax household size.
- Immigration status.
- Medicaid eligibility.
- Other PTC eligibility requirements.
- The specific circumstances reported on the application.
Eligibility should be determined through the official Marketplace application and the applicable rules.
Immigration Status and Document Verification
The Marketplace may verify information reported on an application and may request additional documentation when information cannot be electronically verified or does not match available records.
If you receive a request for documentation:
Do not ignore it.
Review:
- What information needs to be verified.
- Which documents are acceptable.
- The deadline for submitting them.
- Whether the Marketplace successfully received the documents.
A data matching issue does not necessarily mean a person is ineligible. It may mean the Marketplace needs additional information to complete its verification.
Special Enrollment Periods in 2027
After January 15, 2027, you will generally need to qualify for a Special Enrollment Period (SEP) to enroll in or change Marketplace plans.
Certain life events that may qualify someone for a SEP include:
- Losing qualifying health coverage.
- Getting married.
- Having a baby.
- Adopting a child.
- Certain changes in residence.
Specific rules and deadlines depend on the qualifying event. In many situations, HealthCare.gov provides a window of approximately 60 days related to the qualifying event.
Will the Monthly 150% FPL Special Enrollment Period Continue?
Consumers should not assume that the monthly 150% FPL SEP is available for 2027.
CMS finalized a policy that continues to prohibit Exchanges from offering the 150% FPL SEP after Plan Year 2026.
Consumers who need coverage after Open Enrollment should therefore determine whether they qualify for another applicable Special Enrollment Period.
Medicaid and CHIP
Medicaid and the Children’s Health Insurance Program (CHIP) operate differently from the Marketplace Open Enrollment Period.
Consumers may apply for Medicaid or CHIP at any time during the year.
Immigrants may be subject to additional requirements involving immigration status, state residency, and waiting periods.
HealthCare.gov explains that many “qualified non-citizens” are generally subject to a five-year waiting period for Medicaid and CHIP, although exceptions and special rules exist.
Rules can also vary by state.
What If My Current Plan Will Not Be Available in 2027?
Do not panic if you receive a notice stating that your current health plan will not continue in 2027.
However, do not ignore the notice either.
During Open Enrollment, review the plans available for 2027 and select coverage for which you are eligible.
When comparing plans, do not look only at the monthly premium.
Also review:
- Deductible.
- Copayments.
- Coinsurance.
- Maximum out-of-pocket costs.
- Doctors and specialists.
- Hospitals.
- Pharmacies.
- Prescription medications.
- Provider network.
- Covered benefits.
A plan with a lower monthly premium is not necessarily the plan that best fits every person’s medical needs.
Remember to Pay Your First Premium
Completing a Marketplace application and selecting a plan does not necessarily mean your coverage is active.
HealthCare.gov instructs consumers to pay the first premium directly to the insurance company for coverage to begin.
Keep confirmation of your payment and verify that the insurance company shows your coverage as active.
What Should You Prepare Before Enrolling or Renewing?
Preparing in advance can make the enrollment process much easier.
Have the following information available:
- Information for household members.
- Dates of birth.
- Social Security numbers when applicable.
- Immigration documents when applicable.
- Expected annual household income for 2027.
- Employer information.
- Information about other health coverage available to the household.
- Current health insurance information.
- List of doctors and specialists.
- Preferred hospitals.
- Prescription medication list.
- Notices received from the Marketplace or insurance company.
Do Not Automatically Renew Without Reviewing Your Coverage
Even if your current plan can be renewed, 2027 is an especially important year to review your information before allowing coverage to renew.
Review these six areas:
1. Eligibility
Has anything changed in your household, income, employment, or immigration situation?
2. Financial assistance
Does the Marketplace show a different APTC amount for 2027?
3. Monthly premium
How much will you actually pay each month?
4. Provider network
Are your doctors, specialists, and hospitals still participating?
5. Prescription drugs
Are your medications still covered, and under what conditions?
6. Available plans
Is another available plan a better fit for your healthcare needs and circumstances?
