Protecting Health Care and Lowering Costs Act of 2025

This bill adjusts health insurance subsidies by modifying the premium tax credit structure under the Internal Revenue Code. It replaces previous income thresholds with a sliding-scale formula, increasing subsidies for households earning between 150% and 400% of the federal poverty level - reducing their required premium payments as income rises within these tiers. The changes apply to tax years beginning after December 31, 2025, directly affecting middle-income individuals and families purchasing coverage through health insurance marketplaces. It also repeals specific provisions from a prior reconciliation law related to health care.
