Up to 400,000 Californians may lose affordable health insurance if ACA tax credits aren’t extended by Dec. 31, 2025.

Up to 400,000 Californians could lose affordable health insurance through Covered California if Congress doesn’t extend the Affordable Care Act’s enhanced tax credits by December 31, 2025. Without the extension, many enrollees may face premiums rising by up to 97%, threatening coverage for low- and middle-income residents. Advocates, including former Speaker Nancy Pelosi, are urging enrollment during open enrollment and pushing lawmakers to act, warning of a potential coverage gap amid ongoing budget negotiations.
