This bill aims to extend the enhanced health care premium tax credits established under the Internal Revenue Code of 1986. Specifically, it prolongs the period during which individuals can receive increased premium assistance amounts for health insurance purchased through marketplaces. The legislation also extends the provision that allows taxpayers whose household income exceeds 400 percent of the federal poverty line to qualify for these premium tax credits. These enhancements, originally set to expire at the end of 2025, would now be extended through 2028, applying to taxable years beginning after December 31, 2025.
