As Congress debates federal health care spending as part of spending bill negotiations, including extending the enhanced premium tax credits, the latest KFF Health Tracking Poll finds three-quarters (78%) of adults say Congress should extend the enhanced tax credits for people who buy their own insurance through the ACA Marketplace. This is more than three times the share of the public (22%) who say Congress should let the credits expire. Notably, majorities across political party want Congress to extend the tax credits including nine in ten (92%) Democrats, eight in ten (82%) independents, and six in ten (59%) Republicans. A majority of Republicans who align with the MAGA movement (57%) also say Congress should extend these subsidies.

This KFF Health Tracking Poll was designed and analyzed by public opinion researchers at KFF. The survey was conducted September 23-29, 2025, online and by telephone among a nationally representative sample of 1,334 U.S. adults in English (n=1,255) and in Spanish (n=79). The sample includes 1,026 adults (n=64 in Spanish) reached through the SSRS Opinion Panel either online (n=1,004) or over the phone (n=22). The SSRS Opinion Panel is a nationally representative probability-based panel where panel members are recruited randomly in one of two ways: (a) Through invitations mailed to respondents randomly sampled from an Address-Based Sample (ABS) provided by Marketing Systems Groups (MSG) through the U.S. Postal Service’s Computerized Delivery Sequence (CDS); (b) from a dual-frame random digit dial (RDD) sample provided by MSG. For the online panel component, invitations were sent to panel members by email followed by up to three reminder emails.
