What Happens When Healthcare Subsidies Expire?

Millions of Americans are bracing for sharp increases in health insurance premiums as key Affordable Care Act (ACA) subsidies are set to expire at the end of December. These subsidies, often called premium tax credits, have kept ACA Marketplace plans affordable for more than 22 million people.

Without an extension, monthly premiums are expected to more than double for many households, putting coverage at risk during a period of rising medical costs and economic uncertainty. According to the Kaiser Family Foundation research, the average ACA enrollee could pay $1,016 more per month in 2026 if the subsidies lapse.

This shift has triggered a major political showdown. The White House had been preparing to propose a two-year extension of these subsidies, along with new eligibility rules, but Republicans in Congress pushed back, delaying any announcement.

Multiple outlets (including Politico, CNN, and MS Now) reported that the proposal would cap eligibility at 700% of the federal poverty level (FPL), adjust out-of-pocket subsidies, and allow some tax credits to be redirected into tax-advantaged savings accounts. But with congressional resistance, millions of Americans still don’t know whether their premiums will skyrocket in just weeks.

The stakes are huge: without these subsidies, families may find Marketplace insurance unaffordable, causing many to drop coverage or skip medical care.

What exactly is expiring?

The expiring subsidies are the enhanced ACA premium tax credits originally expanded during the Covid-19 pandemic and later extended through legislation. These credits lower the monthly cost of Marketplace insurance for low- and middle-income households. They also expanded eligibility so more people, especially middle-income families, could qualify.

If Congress does not extend them:

• Many households are expected to see premiums double or even triple

• Some enrollees could lose eligibility entirely

• Millions may be forced to switch to higher-deductible, less comprehensive plans

• Some may drop coverage altogether

KFF estimates that about 22 million ACA enrollees will be directly affected.

Why is this happening now?

During the pandemic, the expanded subsidies were originally created with a Dec. 31, 2025 expiration date, meaning Congress must vote to continue them or they disappear.

Although the White House planned to propose a two-year extension tied to new eligibility limits and rules, the rollout was stalled after House and Senate Republicans objected to extending ACA affordability protections.

Some argued that the subsidies should be allowed to expire; others worried about political fallout heading into the 2026 midterms, where millions of voters could lose affordable coverage.

Who is most affected by subsidies expiring?

Millions of people could feel the impact if the ACA subsidies expire, but some groups are hit much harder than others:

1. People receiving ACA premium tax credits: Anyone who currently gets subsidized Marketplace coverage is at risk.

2. Low- and middle-income families: Even families making 300–600% of the federal poverty level (about $45,000–$180,000 for a family of four) could see huge premium increases.

3. Older adults under 65: Because premiums rise sharply with age, people in their 50s and early 60s face the largest dollar increases.

4. Residents in high-cost states: States like Alaska, Wyoming, West Virginia, Montana, and Florida already have high premiums. Without subsidies, some plans become nearly unaffordable.

5. People who recently left employer insurance: If you rely on Marketplace plans because you’re self-employed, between jobs, or working part-time, these changes hit especially hard.

What would Trump's proposal have done?

According to Politico and CNN’s reporting, the unreleased White House proposal (which has been opposed by Congressional Republicans) included:

• A two-year subsidy extension preventing immediate premium hikes through 2027.

• A cap on eligibility at 700% of the federal poverty level, limiting higher-income households' access to subsidies.

• New funding to reduce out-of-pocket costs, potentially lowering deductibles or copays.

• A new option to deposit unused/excess tax credits into a tax-advantaged savings account to help pay for other medical needs.

What happens if the subsidies expire?

If Congress does nothing before the deadline, here’s what Americans can expect in January 2026:

• Premiums rise immediately: Families could see premium hikes from hundreds to thousands per month.

• Many lose eligibility altogether: Households above certain income thresholds may no longer qualify for any financial help.

• Marketplace “sticker shock”: People shopping for plans during ACA open enrollment (Nov 2025–Jan 2026) will see drastically higher prices.

• Higher risk of going uninsured: KFF warns that millions could drop coverage due to unaffordable premiums.

• States may offer temporary fixes: But state-level funding is limited and cannot replace federal subsidies.

What can you do right now?

Here's what you need to do amidst all the uncertainty surrounding health insurance subsidies:

1. Log in to HealthCare.gov and review your 2025–26 options. Check whether your current plan will increase next year.

2. Compare lower-premium options. Silver and Bronze plans may be cheaper, but check deductibles carefully.

3. See if you qualify for Medicaid. If your household income has dropped, Medicaid may offer free or very low-cost coverage.

4. Check for state-based subsidies. Some states (CA, NJ, WA, CO) offer extra financial help.

5. Follow the subsidy debate closely. Congress is expected to vote in December as part of the shutdown deal.

The bottom line

If the ACA subsidies expire, millions of people will face higher premiums, reduced coverage options, and difficult decisions about their health care. The White House appears ready to support a short-term extension, but Congress is divided, and time is running out. Whether you rely on Marketplace coverage or know someone who does, now is the time to check your options, compare plans, and stay informed.
