The 2026 Affordable Care Act (ACA) Marketplace Open Enrollment period begins on November 1, 2025, bringing significant financial and policy changes for millions of Americans. One of the most pressing issues involves the expiration of enhanced premium tax credits. These credits have provided substantial financial relief for enrollees, especially middle-income individuals and families earning above four times the federal poverty level. If Congress does not act before the end of 2025, these enhanced subsidies will lapse, potentially leading to steep premium increases.
According to the Kaiser Family Foundation (KFF), subsidized enrollees could see their out-of-pocket premiums rise by an average of 114%. Individuals with incomes below four times the poverty level will still qualify for standard tax credits, but with reduced financial support. Those earning above this threshold will lose eligibility entirely, facing higher premiums without federal aid. Without congressional intervention, these changes could trigger substantial coverage losses, particularly among younger and healthier participants, further driving up premium costs across the Marketplace.
Increased Repayment Obligations at Tax Time
Beginning in the 2026 plan year, changes enacted under the 2025 budget reconciliation law will eliminate repayment limits on excess premium tax credits. This means that Marketplace enrollees whose actual incomes exceed initial estimates will have to repay the full amount of excess subsidies when filing 2026 taxes. For individuals with variable incomes, such as self-employed or gig workers, this shift could lead to large and unexpected tax bills.
If enhanced premium credits expire, the reintroduction of the “subsidy cliff” will particularly impact those who unintentionally cross the four-times-poverty threshold. These enrollees may owe thousands—or even tens of thousands—of dollars in repayments. The Marketplace continues to encourage users to report mid-year income changes promptly to adjust advance credits and avoid severe tax liabilities.
Shift Toward Higher Deductible Health Plans
With premiums expected to rise, many enrollees may opt for less expensive plans, such as bronze or catastrophic options, which come with significantly higher deductibles. The Centers for Medicare & Medicaid Services (CMS) plans to simplify hardship exemptions for individuals whose incomes fall outside premium tax credit eligibility, allowing broader access to catastrophic plans. In 2026, these plans will carry annual deductibles of $10,600 for individuals and $21,200 for families.
Additionally, the budget reconciliation law expands the definition of high-deductible health plans (HDHPs), allowing all Marketplace bronze and catastrophic plans to be paired with Health Savings Accounts (HSAs). Enrollees may also use HSAs to cover telehealth and remote services before meeting deductibles—potentially increasing HSA utilization across the ACA Marketplace.
Reduced Coverage for Certain Lawfully Present Immigrants
Policy adjustments beginning in 2026 will eliminate premium tax credit eligibility for certain lawfully present immigrants with incomes below 100% of the federal poverty level (FPL). These individuals, who are currently excluded from Medicaid due to recent residency, will no longer qualify for subsidized Marketplace coverage. By 2027, further restrictions will narrow eligibility to specific immigrant categories such as lawful permanent residents and certain entrants under the Refugee Education Assistance Act of 1980. Refugees, asylees, and survivors of human trafficking will lose subsidy access under these new rules.
End of Year-Round Enrollment for Low-Income Consumers
Until recently, individuals with incomes at or below 150% FPL could enroll at any time through the “low-income special enrollment period” (SEP). However, beginning August 25, 2025, this provision will be rescinded as part of the Marketplace Integrity and Affordability Rule. The 2025 budget reconciliation law effectively makes this change permanent, preventing most consumers from qualifying for premium tax credits when enrolling through income-based SEPs. The shift is expected to limit flexible access for lower-income individuals who previously benefited from continuous enrollment opportunities.
Significant Cuts to Federal Navigator Funding
In February 2025, CMS announced a drastic reduction in federal Navigator funding—from $100 million to just $10 million for the 2026 plan year. This 90% cut severely limits community-based organizations that assist consumers with plan selection and enrollment. For example, funding in Louisiana dropped from $2.46 million to $250,000, while North Carolina saw reductions from $7.4 million to $750,000. The shortfall could hinder outreach and consumer education, particularly in underserved areas.
Although brokers and agents now facilitate a larger share of enrollments, their financial ties to insurers have raised ethical concerns. Recent Department of Justice investigations have uncovered fraudulent practices by some brokers, emphasizing the need for regulatory oversight and independent consumer assistance.
DACA Recipients Lose Marketplace Access
The 2024 Biden administration rule permitting Deferred Action for Childhood Arrivals (DACA) recipients to access Marketplace and Basic Health Program (BHP) coverage was reversed under the 2025 program integrity regulation. As of August 25, 2025, DACA recipients are no longer eligible for Marketplace enrollment or related subsidies. Those previously covered lost eligibility effective September 30, 2025, leaving them without ACA-backed health coverage in most states.
Legal Challenges Stall Implementation of Key Regulatory Changes
Several components of the Trump Administration’s program integrity regulation are currently blocked by a federal court. In City of Columbus et al. v. Kennedy, the court issued an injunction halting multiple provisions, including new documentation requirements for income verification and mandatory $5 monthly premiums for automatic re-enrollees. The court determined that the Administration likely exceeded its authority under the ACA, pending further litigation. These ongoing legal battles will shape the regulatory environment heading into the 2026 enrollment season.
Navigating Change in 2026
The 2026 ACA Open Enrollment period marks one of the most consequential shifts in Marketplace history. From expiring subsidies and tightened eligibility to reduced outreach funding, consumers will face new complexities when choosing coverage. Policymakers, healthcare providers, and advocacy organizations must work collaboratively to mitigate disruptions and ensure that Americans continue to access affordable and comprehensive health insurance coverage.
