How it started
What happened
The Affordable Care Act marketplace rules define premium subsidy eligibility based on household income. Enhanced ACA premium tax credits expired on January 1, 2026, and marketplace enrollment subsequently fell from 22.1 million to 19.2 million in one year. Eligibility for subsidies is determined by Modified Adjusted Gross Income (MAGI) against the federal poverty level, not by net worth.

Why it matters
The subsidy threshold at 400% of the federal poverty level means that exceeding this limit by even one dollar eliminates the entire subsidy credit for the year. The lack of enhanced tax credits has increased the appeal of alternative health plans that do not meet comprehensive ACA standards, which have lower premiums but limited coverage.
