Enhanced premium tax credits are set to expire at the end of 2025 and have been at the center of tensions in Congress. Fifty-two-year-old Dinam Bigny sank into debt and had to get a roommate this year, in part because of health insurance premiums that cost him nearly $900 per month.Next year, those monthly fees will rise by $200 — a significant enough increase that the program manager in Aldie, Virginia, has resigned himself to finding cheaper coverage.“I won’t be able to pay it, because I really drained out any savings that I have right now,” he said. “Emergency fund is still draining out — that’s the scary part.”Bigny is among the many Americans dependent on Affordable Care Act marketplace health insurance plans who are already struggling with the high cost of health care, according to a new survey from the health care research nonprofit KFF.Most of the more than 1,300 enrollees surveyed in early November say they anticipate that their health costs will be impacted next year if Congress doesn’t extend expiring COVID-era tax credits that help more than 90% of enrollees pay for health insurance premiums, per KFF. The possibility of an extension looks increasingly unlikely.The enhanced premium tax credits set to expire at the end of this year have been at the center of recent tensions in Congress, with Democrats calling for a straight extension and several Republican lawmakers vehemently opposed to the idea. Their inability to agree on a path forward fueled a record 43-day government shutdown earlier this fall.President Donald Trump and some Republicans in Congress have circulated proposals in recent weeks to offer a short-term extension or reform the Affordable Care Act, but no plan has emerged as a clear winner. Meanwhile, the window for Americans to shop for next year’s plans is well underway with less than a month to go until the subsidies expire.KFF’s poll reveals that marketplace enrollees — most of whom say they would be directly impacted by the subsidies expiring — overwhelmingly support an extension. The survey found this group is more likely to blame Trump and Republicans in Congress than Democrats if the tax credits are left to expire.
