What Is Open Enrollment for Health Insurance?
Open enrollment is the designated window each year when individuals and families can sign up for a new health insurance plan, renew existing coverage, or switch to a different plan through the Health Insurance Marketplace.
Outside of this window, enrollment is generally not permitted unless a qualifying life event triggers a Special Enrollment Period (SEP). This annual structure applies to plans sold through the ACA Marketplace (also called Obamacare or HealthCare.gov), as well as many employer-sponsored plans, though the exact timing for employer plans varies by company.
The Health Insurance Marketplace, created under the Affordable Care Act (ACA), allows consumers to compare and purchase ACA-compliant plans, often with income-based subsidies called premium tax credits that reduce monthly premiums.

2026 Open Enrollment Dates: Federal and State-by-State
For most of the country, the 2026 open enrollment period ran from November 1, 2025 to January 15, 2026, as confirmed by HealthCare.gov. According to the Centers for Medicare and Medicaid Services (CMS), approximately 22.8 million consumers selected a Marketplace plan during the 2026 open enrollment period, including 15.6 million through HealthCare.gov and 7.2 million through state-based exchanges.
A few states operate their own exchanges and set their own deadlines. According to eHealth's state-by-state breakdown, the 2026 enrollment dates broke down as follows.
Federal Marketplace States (Standard Timeline)
Thirty states use HealthCare.gov and follow the national schedule of November 1, 2025 to January 15, 2026. These include Alabama, Alaska, Arizona, Arkansas, Delaware, Florida, Hawaii, Indiana, Iowa, Kansas, Louisiana, Michigan, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia, Wisconsin, and Wyoming.
State-Based Marketplaces (Standard Timeline)
Thirteen states run their own exchanges but follow the same November 1 to January 15 schedule. These include Colorado, Connecticut, Georgia, Illinois, Kentucky, Maine, Maryland, Minnesota, Nevada, New Mexico, Pennsylvania, Vermont, and Virginia.
State-Based Marketplaces (Extended Deadline)
Six states and Washington, D.C. extended their open enrollment window through January 31, 2026: California, New York, New Jersey, Rhode Island, the District of Columbia, and Massachusetts. Massachusetts set its deadline to January 23, 2026.
Idaho (Shorter Window)
Idaho opened its enrollment period early on October 15, 2025 and closed it on December 15, 2025. All plans enrolled in Idaho began January 1, 2026, with no February start option.
Deadline Breakdown: What December 15 vs. January 15 Actually Means
The enrollment deadline determines when coverage begins, not just when the paperwork is due.
Enrolled by December 15, 2025: Coverage starts January 1, 2026.
Enrolled between December 16 and January 15, 2026: Coverage starts February 1, 2026.
Enrolled in an extended-deadline state after December 15: Coverage starts February 1, 2026 for those who enrolled in January.
This distinction matters for a practical reason. Anyone needing coverage to begin on January 1, for example to coordinate with a new job or the end of COBRA, had to complete enrollment by December 15. Those who enrolled in January retained coverage options but started their plan one month later.
HealthCare.gov confirms that coverage starts on January 1 only when enrollment and first premium payment are completed by the December 15 deadline.
What Changed for 2026 Health Insurance
Several significant changes came into effect for the 2026 plan year. Understanding them helps explain why premiums are higher and why some previous enrollment options are no longer available.
Enhanced Premium Tax Credits Expired
The most consequential change for 2026 is the expiration of the enhanced premium tax credits (enhanced PTCs) that were introduced during the COVID-19 pandemic and extended through 2025. As Avera Health Plans explains, Congress did not renew these credits, so they expired on December 31, 2025.
Standard premium tax credits still exist for qualifying households, those with incomes generally between 100% and 400% of the Federal Poverty Level. The enhanced credits had extended eligibility to higher income levels and reduced premiums more substantially, including reducing monthly costs to zero for many lower-income enrollees. With the enhanced credits gone, those households now pay more each month, though standard subsidy support remains.
Why Health Insurance Is Going Up in 2026
Premiums increased in 2026 for two connected reasons. First, the expiration of enhanced tax credits means enrollees receive less financial assistance, so out-of-pocket premium costs rise even when the base plan price stays the same. Second, insurers raised base premiums in response to rising healthcare costs across the system.
Avera Health Plans notes that these premium changes apply across all insurance companies on the Marketplace, so switching carriers does not avoid the increases. Comparing plan tiers may still yield savings. A Bronze plan or a plan with a higher deductible may carry a lower monthly premium than a Silver plan, though out-of-pocket costs when care is needed will be higher.
The Low-Income Special Enrollment Period Was Eliminated
Previously, households with incomes at or below 150% of the Federal Poverty Level could enroll in Marketplace coverage year-round through a dedicated low-income Special Enrollment Period. HealthCare.gov confirms that this year-round enrollment option no longer applies for 2026. Low-income households now follow the same standard enrollment windows as everyone else, unless a qualifying life event applies.
2026 Is the Last Year with Extended January Enrollment
Starting with the 2027 plan year, meaning the open enrollment period beginning in fall 2026, all states will end open enrollment on December 31. The current January extensions will no longer be available. Anyone who has relied on an extended-deadline state in prior years will need to act earlier during the upcoming cycle.
DACA Recipients Are No Longer Eligible for Marketplace Coverage
As confirmed by HealthCare.gov, recipients of Deferred Action for Childhood Arrivals (DACA) are no longer eligible to enroll in ACA Marketplace plans for 2026. Those affected may wish to consult a licensed insurance navigator or community health center to explore available alternatives.
How to Enroll: A Step-by-Step Walkthrough
Even though the 2026 open enrollment period has closed, this walkthrough is useful for anyone preparing for the 2027 enrollment period, which opens November 1, 2026, or for those enrolling through a Special Enrollment Period.
Step 1: Gather your documents. Before starting an application, collect recent pay stubs or tax returns to confirm household income, Social Security numbers for all household members, current health insurance information if applicable, and a list of any regular prescriptions or preferred doctors. People managing chronic conditions such as heart disease or diabetes should confirm that their medications and treating specialists fall within a plan's network and formulary before finalizing a selection.
Step 2: Create or log in to your HealthCare.gov account. Go to HealthCare.gov and create an account or log in. If your state uses its own exchange, such as Covered California, NY State of Health, or Connect for Health Colorado, go to that state's marketplace website instead.
Step 3: Complete the application. The application asks about household size, income, and citizenship status. Based on those answers, the system calculates which plans and financial assistance options are available. No medical history questions are asked. ACA plans cannot deny coverage or charge more based on health conditions.
Step 4: Compare plans. Plans are organized into metal tiers: Bronze, Silver, Gold, and Platinum. Bronze plans have lower monthly premiums but higher out-of-pocket costs when care is used. Platinum plans have higher premiums but lower costs at the point of care. Silver plans are the only tier eligible for cost-sharing reductions for those who qualify based on income. People who anticipate frequent care visits, such as those managing diabetes or other ongoing conditions, may find that a Silver or Gold plan lowers total annual costs even when the monthly premium is higher.
Step 5: Enroll and pay the first premium. Coverage does not begin until the first premium payment is made. After selecting a plan, follow the insurer's payment instructions. HealthCare.gov advises paying the first premium directly to the insurance company to activate coverage.
Step 6: Confirm enrollment. Log back into the account to confirm the plan is active, and watch for a member ID card from the insurer. Contact the insurer directly with any questions about specific coverage details.
If navigating this process feels overwhelming, a licensed enrollment counselor can help. To find in-person assistance, use the local help finder on HealthCare.gov or connect through Momentary Lab to identify the right support for your situation.
Missed Open Enrollment? Special Enrollment Periods Explained
Missing open enrollment does not automatically mean going without coverage for the rest of the year. A Special Enrollment Period (SEP) allows enrollment outside the standard window when a qualifying life event has occurred.
SEPs generally open a 60-day window from the date of the qualifying event. Acting within that window is important, as coverage cannot be backdated once the period closes.
What Qualifies for a Special Enrollment Period?
The following life events typically trigger a Special Enrollment Period, according to HealthCare.gov:
- Loss of health coverage: losing job-based coverage, aging off a parent's plan at 26, losing Medicaid eligibility, or losing COBRA coverage
- Household changes: marriage, divorce, having or adopting a child
- Moving: relocating to a new area with different plan options
- Changes in income or household size that affect subsidy eligibility
- Gaining citizenship or lawful immigration status
How to Get Health Insurance After Losing a Job
Losing employer coverage is one of the most common qualifying events. When job-based coverage ends, a 60-day SEP window opens. During that period, enrollment in a Marketplace plan is available, and premium tax credits may apply depending on income.
COBRA allows continuation of the previous employer's plan, but at the full premium cost without an employer contribution, which is typically higher than what was deducted from a paycheck. Comparing COBRA against Marketplace plan costs within the 60-day window before committing is generally a practical step. A licensed advisor can help evaluate both options based on individual healthcare needs.
Can You Sign Up for Health Insurance Anytime?
Outside of open enrollment and Special Enrollment Periods, enrollment in ACA-compliant Marketplace plans is not generally available. Medicaid and CHIP are exceptions, as they accept applications year-round for those who qualify based on income and household size.
Short-term health plans are available outside of OEP but do not meet ACA standards and typically exclude pre-existing conditions, preventive care, and other key benefits. This matters most for people managing ongoing conditions, since those conditions may receive no coverage under a short-term plan. A licensed advisor can advise on whether short-term coverage is appropriate for a specific situation.
How Long Does It Take to Get Health Insurance?
Once enrolled and the first premium is paid, coverage typically begins on the first day of the following month, or January 1 if enrolled by December 15 during OEP. In some SEP cases, coverage can begin sooner. The HealthCare.gov application is processed in real time, and an insurer will follow up with plan confirmation and member ID card details directly.
Employer Open Enrollment: How It Differs from the Marketplace
Employer-sponsored health insurance operates on a separate schedule from the ACA Marketplace, and the two systems do not overlap.
Most employers hold their open enrollment period in October or November, with coverage beginning on January 1 of the following year. The exact dates vary by employer and are set by the company's HR department, not by the federal government.
Several important differences apply:
- Subsidy eligibility: Those enrolled in employer-sponsored coverage generally cannot receive Marketplace premium tax credits, even if the employer plan is costly. An exception exists if the employer plan is deemed unaffordable under ACA rules, meaning the employee's share of the self-only premium exceeds a defined percentage of household income.
- Plan options: Employer plans are negotiated directly between the employer and the insurer. Options may be more limited than Marketplace offerings in some cases, or more comprehensive in others.
- COBRA: When employer coverage ends due to job loss, reduced hours, or leaving a position, COBRA allows temporary continuation of the same plan, typically for up to 18 months. COBRA premiums reflect the full cost of coverage without an employer contribution, which is generally higher than the payroll deduction previously paid.
Employees with questions about whether their employer plan qualifies as affordable under ACA guidelines can consult HR, a licensed insurance agent, or use the employer plan affordability calculator at healthinsurance.org.
If employer coverage does not fit a particular situation, finding a doctor who participates in Marketplace plans is a practical step when evaluating individual coverage options.
Frequently Asked Questions
Is open enrollment for 2026 still until January 15th?
In most states, the 2026 open enrollment period ended on January 15, 2026. A handful of states with extended deadlines, including California, New York, New Jersey, Rhode Island, Massachusetts, and Washington, D.C., allowed enrollment through late January 2026. Idaho closed its enrollment window earlier, on December 15, 2025. As of March 2026, the 2026 open enrollment period has closed in all states. Enrollment is now only possible through a Special Enrollment Period triggered by a qualifying life event, or through year-round programs like Medicaid and CHIP.
What is open enrollment for health insurance in the USA?
Open enrollment is the annual window during which individuals can sign up for a new health insurance plan, renew current coverage, or change plans through the ACA Health Insurance Marketplace or an employer. Outside of open enrollment, enrollment in most ACA-compliant plans is not available unless a qualifying life event, such as job loss, marriage, or the birth of a child, triggers a Special Enrollment Period. For 2026 coverage, the federal open enrollment period ran from November 1, 2025 to January 15, 2026.
What is the open enrollment period for Covered California 2026?
Covered California, the state's ACA Marketplace, ran its 2026 open enrollment period from November 1, 2025 through January 31, 2026, an extended window compared to the federal standard of January 15. Residents who enrolled by December 15, 2025 received coverage beginning January 1, 2026. Those who enrolled between December 16 and January 31 received coverage beginning February 1, 2026. Covered California manages its own exchange independently of HealthCare.gov.
Why is health insurance going up in 2026 in the USA?
Health insurance costs increased in 2026 for two main reasons. First, the enhanced premium tax credits introduced during the COVID-19 pandemic and extended through 2025 expired on December 31, 2025. These credits had reduced out-of-pocket premiums for millions of enrollees, particularly those with moderate to higher incomes. With those credits gone, consumers receive less financial assistance, so their share of the monthly premium rises. Second, insurers raised base plan premiums in response to rising healthcare costs. As noted by Avera Health Plans, these increases apply across all insurers on the Marketplace, not just selected carriers.
