If Congress lets Affordable Care Act (ACA) tax credits designed to lower monthly health insurance premiums expire in December 2025, the average annual premium in Arizona could climb by $639, or 138%, according to a Center for American Progress analysis.
The credits are generally available to U.S. citizens or legal residents who lack subsidized coverage, have incomes at or above the federal poverty line and are not incarcerated. As of 2025, more than 400,000 Arizonans receive health coverage through the ACA, and about 91% rely on premium tax credits to afford insurance, according to nonpartisan research organization KFF.
If the credits expire, experts warn that healthier people may forgo coverage, shrinking the overall insurance pool. With fewer healthy enrollees offsetting costs, premiums and out-of-pocket expenses would likely rise. In Arizona, average annual costs could jump from $463 to $1,102 per person.
