Quick Answer
For the 2026 plan year the Affordable Care Act marketplace lost the enhanced premium tax credits that were in place since 2021, average benchmark premiums rose by roughly 58 percent before subsidies, and the year round Special Enrollment Period for low income applicants was eliminated. Most consumers must now enroll between November 1, 2025 and January 15, 2026 to have coverage for 2026.
If you already had a 2025 marketplace plan and did nothing, you were either auto reenrolled into a similar plan or downgraded to a lower premium option, and a new $5 monthly fee may apply if you were auto enrolled into a net zero premium plan without verifying your information.
The Headline: Enhanced Subsidies Expired
The biggest change in 2026 was not new policy. It was the policy that ended. The enhanced premium tax credits that were first passed during the COVID-19 pandemic and extended through the Inflation Reduction Act expired at the end of 2025 after Congress did not pass another extension.
Those enhanced credits did two things. They capped the share of household income that anyone had to pay for a benchmark Silver plan at 8.5 percent, and they removed the so called subsidy cliff for households earning above 400 percent of the Federal Poverty Level. With both of those rules gone, the original ACA subsidy structure is back in force.
The real world effect: average marketplace premiums after subsidies rose roughly 58 percent for 2026. The Kaiser Family Foundation initially warned that the increase could be even higher, but real world data showed many consumers proactively shopped down to Bronze or low cost Silver plans to limit the monthly hit.
Year Round Enrollment for Low Income Households Is Gone
Since 2022, applicants earning under 150 percent of the Federal Poverty Level could enroll in marketplace coverage at any point in the year. That safety net was removed for 2026.
Now, regardless of income, you can only enroll during the standard Open Enrollment Period or during a traditional Special Enrollment Period tied to a qualifying life event such as job loss, marriage, divorce, birth of a child, or a move to a new state.
The standard Open Enrollment window for 2026 plans ran November 1, 2025 to January 15, 2026 in most states. State based marketplaces in places like California, New York and Washington have their own slightly different deadlines.
Auto Reenrollment Now Comes With a $5 Fee in Some Cases
To reduce silent coverage from people who never confirm their information, HealthCare.gov introduced a $5 monthly fee for consumers who are automatically reenrolled into a net zero premium plan without actively logging in to verify income and household details.
The fix is simple. Log into HealthCare.gov during Open Enrollment, click through the renewal screens, and confirm or update your projected income, household size and address. That removes the $5 charge and ensures your tax credit is accurate.
New Income Floor for Lawfully Present Immigrants
Starting with 2026 plans, lawfully present immigrants must have household income above 100 percent of the Federal Poverty Level to qualify for premium tax credits. Lawfully present individuals who earn below 100 percent of the FPL and are ineligible for state Medicaid because of their immigration status can no longer receive marketplace subsidies.
This is a meaningful change for very low income legal residents, many of whom previously qualified for full premium subsidies under the enhanced rules.
Essential Health Benefits Adjustments
Federal rules no longer require state marketplaces to include gender affirming care within the basket of Essential Health Benefits that every qualified health plan must cover. That decision is back in the hands of individual state insurance commissioners.
For consumers, this means coverage for these services is now a state by state question. Check your specific plan's Summary of Benefits and Coverage before assuming a service is included.
Data Matching Deadlines Are Strict
If the income you report on your application does not match historical IRS records, the marketplace flags a Data Matching Issue (DMI). You have 90 days to upload pay stubs, a tax return, or a letter from your employer to resolve it.
If you miss the 90 day window your premium tax credit can be reduced or eliminated, and the marketplace can adjust your coverage retroactively. This was always the rule, but with the higher 2026 unsubsidized premiums, missing the deadline is now a much more expensive mistake.
What These Changes Mean for Your Wallet
The practical impact depends on income.
- Households between 100 and 250 percent FPL. Still qualify for premium tax credits and cost sharing reductions, but monthly premiums after subsidies are higher than in 2025. Sticking with a Silver plan is usually worth it because cost sharing reductions still apply.
- Households between 250 and 400 percent FPL. The biggest premium increases land here. Many shop down to Bronze plans to keep monthly costs manageable.
- Households above 400 percent FPL. The subsidy cliff is back. Above this threshold, you pay full price for marketplace coverage. For some families, an unsubsidized marketplace plan now costs more than a private off exchange plan, so it is worth comparing both.
Practical Steps to Take Right Now
Even though Open Enrollment for 2026 has closed, several actions still matter.
- Verify your current plan. Log into HealthCare.gov or your state exchange and confirm which plan you are actually enrolled in for 2026 and what your monthly premium is.
- Update your projected 2026 income. If your income has changed since you enrolled, update it now. This adjusts your monthly tax credit and prevents a surprise bill at tax time.
- Resolve any open Data Matching Issues. Check your account for outstanding document requests. Upload pay stubs or a letter from your employer immediately if anything is pending.
- Audit your out of pocket exposure. If you downshifted to a Bronze plan, look at the deductible and out of pocket maximum. Set aside money in an HSA if you are eligible.
- Watch for a qualifying life event. Marriage, a new baby, job loss, or a move can trigger a Special Enrollment Period if you want to change plans mid year.
The takeaway
The 2026 ACA marketplace is more expensive and less forgiving than the 2025 version. Enhanced subsidies are gone, year round enrollment for low income households is over, and auto reenrollment can now cost you a small monthly fee if you ignore it. The marketplace still works, and most subsidies still exist, but the cost of being passive went up. Log in, verify, and run the numbers at least once a year so you do not get surprised at tax time.
