A sizeable share of those enrollees are self-employed or own or work at small businesses. Nearly half of adults in the individual health insurance market — the vast majority of which is purchased through Obamacare exchanges — are affiliated with a small business, according to KFF, a nonpartisan health policy research group.

Without the enhanced subsidies, which were enacted by the Biden administration as part of a 2021 Covid-19 relief package, enrollees’ premium payments are expected to jump 114%, on average, next year. The provision’s lapse also means that consumers who make more than 400% of the federal poverty level — about $62,600 for an individual and $84,600 for a couple — will no longer qualify for any federal aid.
