Here's who will be hit with higher premiums if ACA enhanced subsidies expire
"Many marketplace-plan enrollees are over 50, and nearly half are employed by small businesses"
"Many Affordable Care Act insurance enrollees facing premium spikes next year are part of sought-after voting demographics.
The looming premium increase is due to the Dec. 31 expiration of enhanced tax credits for ACA marketplace plans. Congressional Democrats and Republicans are at a standoff over whether to extend the credits.
The ACA established premium tax credits for marketplace-plan enrollees earning up to four times more than the federal poverty level. During the Covid pandemic, Democrats temporarily enhanced the credits by increasing their amount and expanding them to households with incomes above that 400% poverty threshold. They also capped how much a household pays for premiums at 8.5% of income.
Enrollment in marketplace plans has more than doubled since 2020, and most of that growth has been in states won by President Trump.
Also, two key groups of voters would be especially hard hit by the expiration of the enhanced credits: people between the ages of 50 and 64, and small businesses."
