Expiration of Health Insurance Tax Credits Impacts Enrollment and Coverage Costs

The expiration of enhanced tax credits for health insurance premiums through the Affordable Care Act at the end of 2025 has significantly impacted coverage costs in California's San Joaquin Valley. Consequently, Covered California, the state's health insurance marketplace, has reported a marked drop in enrollments, with new sign-ups decreasing by nearly one-third compared to the previous year.

The enhanced tax credits, originally introduced as a temporary measure during the COVID-19 pandemic, provided substantial premium cost reductions for middle-income families. Without congressional intervention to extend these subsidies, many individuals, especially those within the middle-income bracket, are facing heightened out-of-pocket expenses. The Public Policy Institute of California revealed that average annual premiums surged by over $5,200 in Fresno County and more than $10,000 in Merced County for these households.

During the latest open enrollment period, approximately 22,000 individuals in the San Joaquin Valley signed up for new plans, a notable decrease from the nearly 32,400 enrollees the previous year. This decline is largely attributed to the cessation of enhanced tax credits, which had previously enabled middle-income earners to qualify for subsidies. As a result, these individuals now bear the full burden of their premiums.

Shifts in Health Plan Preferences

Covered California continues to offer a variety of health plans, categorized into platinum, gold, silver, and bronze tiers. With platinum plans offering higher premiums but lower deductibles, there’s a noticeable trend where many consumers are opting for lower-tier plans due to increased premium costs. Statewide enrollment data reflects this shift: bronze plan enrollment increased by 23.4% from 2025 to 2026, while higher-tier plans experienced declines.

Jessica Altman, Covered California’s executive director, emphasized the significance of this open enrollment period, stating, "Many Californians see the value in remaining covered, but they had to make sacrifices and shift to lower-tier plans."

Potential Increase in Uninsured Population

Moreover, KFF, an independent health policy organization, reported that numerous individuals are opting out of health insurance due to affordability challenges and competing financial priorities such as housing and utilities. As of 2024, over 291,000 residents in the San Joaquin Valley lacked any form of health insurance.

This evolving landscape could contribute to a growing number of uninsured individuals, driven by both the expiration of premium tax credits and changes in Medicaid eligibility. The Congressional Budget Office forecasts that more than 14 million additional people could be uninsured by 2034 if current policies remain unchanged.
