Subsidy context for 2026
The enhanced premium tax credits from the American Rescue Plan Act and the Inflation Reduction Act expired December 31, 2025, so for plan year 2026 the pre-2021 ACA subsidy structure returns — households above 400% of the federal poverty level receive no premium tax credit at all, and lower-income households pay a larger share of the benchmark plan's premium (Congressional Research Service report R48290; KFF's 2026 premium tracker).
