Marketplace Pulse: What if Enhanced Premium Tax Credits Expire in 2026?
Marketplace Enrollees Will Have to Choose Between Record Premium Increases or Less Coverage
The Marketplace Pulse series provides expert insights on timely policy topics related to the health insurance marketplaces. The series, authored by RWJF Senior Policy Adviser Katherine Hempstead, analyzes changes in the individual market; shifting carrier trends; nationwide insurance data; and more to help states, researchers, and policymakers better understand the pulse of the marketplace.
Oklahoma’s insurance commissioner Glen Mulready recently issued an alert to state residents enrolled in the Affordable Care Act (ACA) marketplace, noting that they could see “substantial increases in premiums” beginning in 2026 if the enhanced Premium Tax Credits are not extended by the end of 2025. Similarly, in a recent letter to congressional leadership, the executives of the State Based Marketplaces observed that the enhanced PTCs had contributed to record enrollment growth, an achievement which was threatened if Congress did not act: “Millions of Americans will experience significant increases in their premiums, the impact of which will be exacerbated by persistent and increasing inflation hitting American families. Health insurance will become unaffordable for many, with disproportionate impacts on older adults, rural communities, small business owners, and families.”
The magnitude of the upcoming health insurance affordability challenge marketplace enrollees will face if the enhanced premium tax credits expire can be seen by modelling the change in tax credits using 2025 premiums. Even switching from a silver plan to the lowest cost bronze plan will not prevent a significant year-over-year premium increase coupled with far higher out-of-pocket costs for many marketplace consumers.
2025 Second-Lowest Silver Plan with and without Enhanced Premium Tax Credits
Once premium tax credits are applied, the second-lowest-silver plan’s (SLS) monthly premium in most states is identical nationwide for subsidized consumers at the same Federal Poverty Level (FPL).1 Table 1 compares the maximum monthly premiums for the SLS plan with the enhanced premium tax credit (IRA) versus the Affordable Care Act (ACA) only tax credits. In 2025, for an enrollee at 250% FPL, the monthly premium for the SLS plan is currently $126 per month with enhanced premium tax credits but would be $243 per month with just the ACA’s tax credits, a 93% increase. Premium increases will be even higher for consumers enrolled in plans besides the benchmark silver plan in 2026 when next year’s premiums reflect insurer uncertainty and adverse selection.
Applying IRA and ACA Tax Credits to the Lowest Silver Plan
For a 40-year-old at 250% FPL currently enrolled in the lowest cost silver plan, premiums without enhanced premium tax credits in 2025 would be anywhere from 93% to 409% higher. For example, the lowest 2025 silver premium is currently $29 per month for a 40-year-old 250% FPL enrollee in Contra Costa County, California, but without the enhanced premium tax credits, that same plan would be $146. Moving from a silver plan to a lower cost bronze plan for consumers at or below 250% FPL is unideal, as they would no longer qualify for cost-sharing reductions and would significantly increase their copay and coinsurance costs.

Many Renewing Consumers Would Pay Higher Premiums Even After Moving to a Bronze Plan
Even moving down from a silver plan to a bronze plan does not guarantee that a subsidized consumer will avoid sharp monthly premium increases if the enhanced premium tax credits end. Figure 2 shows the current 2025 difference in premiums for a silver plan with enhanced premium tax credits (IRA) and a bronze plan with the ACA’s original tax credit amounts. A 40-year-old consumer at 300% FPL switching from the lowest cost silver plan in 2025 (IRA tax credits) to the lowest cost bronze plan (ACA only tax credits) would save $69 per month in Laramie County, Wyoming. However, the same 40-year-old enrollee at 300% FPL in Minnehaha County, South Dakota would pay $124 more per month for the lowest premium 2025 bronze plan with ACA tax credits than the lowest premium 2025 silver plan with IRA tax credits. And even in cases where the bronze premium is lower, the higher out-of-pocket costs and deductible would more than offset the difference.
Congressional districts colored blue in Figure 2 below highlight where the lowest bronze premium without enhanced premium tax credits (ACA) would be higher than the lowest silver premium with enhanced premium tax credits (IRA). Using premiums for a 40-year-old enrollee at 300% FPL, consumers would pay more for a bronze plan with the ACA’s tax credit structure than a silver plan with enhanced premium tax credits in the largest county in 70% of congressional districts, with an average increase of $38 per month for those who would pay more. This difference is likely to be even more pronounced in 2026 if pricing reflects the expected smaller and less healthy market.

If the enhanced premium tax credits’ are not extended, the impact on coverage will be significant. The Urban Institute has estimated that at least 4 million people will become uninsured, with adverse health and economic consequences for individuals and families, and also for health systems and state governments, who will bear the costs of increased demand for charity care. In their letter, the executives of the State Based Marketplaces compare the impact of the enhanced premium tax credits with other tax credits that incentivize investment and make it clear that the stakes are high: “In much the same way other federal income tax credits incentivize Americans to invest in economic development, the updated premium tax credit structure has succeeded in catalyzing millions of Americans to invest in their health and futures. A record 24 million individuals are now enrolled in coverage through the marketplaces. These are hardworking Americans who rely on access to affordable coverage through the individual market: early retirees, small business owners and employees, students, individuals balancing multiple jobs, and families whose employer-sponsored coverage is not affordable.”
