Did the Big Beautiful Bill cut ACA subsidies?

Not directly — but it made them harder to get and riskier to keep, and that is landing at the same time as a separate, bigger cut. As of October 2026, two different things are changing what you pay. First, the One Big Beautiful Bill Act (H.R. 1, Public Law 119-21, signed July 4, 2025) left the basic ACA premium tax credit formula in place but tightened the rules around it: there is no longer any cap on how much of an advance subsidy you may have to repay at tax time (starting with 2026 taxes), you get no subsidy if you enroll through an income-based special enrollment period (starting 2026), most lawfully present immigrants other than green-card holders lose subsidy eligibility (starting January 1, 2027), and subsidized enrollees must verify eligibility before coverage starts (starting plan year 2028). Second — and this is the larger price shock — the enhanced premium tax credits from 2021–2025 expired on December 31, 2025. That expiration was not part of the Big Beautiful Bill; the bill simply did not extend them. The House passed a three-year extension on January 8, 2026, but the Senate has not taken it up, so 2027 subsidies use the original ACA rules, including the 400% of poverty income cap.

What it means

The Big Beautiful Bill and the expired enhanced subsidies are two separate events. News coverage often blends them together.
The core premium tax credit still exists for 2027. If your household income is between 100% and 400% of the federal poverty level and you have no affordable job-based coverage, you can still qualify.
What the bill changed is the fine print: repayment risk, who is eligible, how you enroll, and how often you must prove eligibility.
What the expiration changed is the size of the subsidy: households now pay a larger share of income toward the benchmark plan, and anyone above 400% of the poverty level gets no subsidy at all.
Medicaid changes in the same law (work requirements and six-month eligibility checks for expansion adults starting in 2027) can also push people toward the Marketplace — and failing a Medicaid work requirement now blocks Marketplace subsidies too.

Action steps

Re-check your eligibility during open enrollment, November 1, 2026 to January 15, 2027 in HealthCare.gov states. Enroll by December 15 for coverage starting January 1.
Estimate your 2027 income carefully. With no repayment cap, a low guess can turn into a large tax bill.
Report income changes to the Marketplace during the year as soon as they happen.
If you are not a U.S. citizen, confirm whether your immigration category still qualifies for a subsidy in 2027.
If you are unsure how these changes apply to your household, talk to a licensed agent before you pick a plan.

Risks & deadlines

January 1, 2027: subsidy eligibility narrows for most lawfully present immigrants, and Medicaid work requirements begin in most expansion states.
Spring 2027: when you file 2026 taxes, any excess advance subsidy must be repaid in full — the old caps no longer apply.
Plan year 2028: pre-enrollment verification starts, which effectively ends passive automatic re-enrollment with a subsidy.
Enhanced subsidies could return only if Congress passes a new law; as of October 2026 none has passed.
