Starting Jan. 1, 2026, all Marketplace Bronze and Catastrophic plans will be considered HSA-compatible. This is a significant change because in the past only select Bronze plans were eligible and limited who could open or contribute to an HSA. Now, Marketplace enrollees will have broader access to tax-advantaged savings for health care expenses. (Sec. 71307).
