ACA Open Enrollment Is Here, With Higher Premiums and a Shorter Deadline
If you buy your own health insurance, the next six weeks matter more than usual. Open enrollment for 2027 Affordable Care Act coverage began on November 1, and this year’s season comes with steeper prices, fewer insurers in many areas and tighter eligibility rules. It is also shorter than many people are used to. Searches for the healthcare marketplace climbed as the window opened. Here, we explain what has changed for ACA open enrollment 2027, the key HealthCare.gov deadline, and how to avoid paying more than you need to. Please treat this as general guidance rather than personal insurance or money advice.
The Dates You Need to Know
In most states, which use the federal HealthCare.gov platform, open enrollment runs from November 1 to December 15, 2026. New federal rules now require every marketplace to open by November 1 and close by December 31, so the extended January deadlines some states offered in past years are gone, as healthinsurance.org explains.
Plans chosen during open enrollment take effect on January 1, 2027. If you live in a state that runs its own marketplace, check its website, because some state deadlines differ within the new limits.
Why Many Bills Are Going Up
The biggest change is cost. Enhanced federal subsidies that held down premiums from 2021 through 2025 ran out after 2025, and carriers have pushed rates higher once more. Across the country, the typical insurer is asking for roughly 15% more for 2027 individual plans, ranging from under 7% in a few states to roughly 29% in Arizona, according to analysis summarized in healthinsurance.org’s guide to the 2027 changes.
Subsidies still help most enrollees
That headline number can be misleading. Early in 2026, roughly 87% of people with marketplace plans were getting help with their premiums, and those subsidies are tied to the price of a benchmark silver plan in each area. When benchmark prices rise, subsidies usually rise too. That means many people will be partly shielded from the increases. People who earn too much for help, or who buy coverage outside the marketplace, will feel the full jump.
Other Changes That Could Affect You
Several quieter changes deserve attention:
- Insurers are leaving. Carriers are pulling out in over 20 states, ending hundreds of thousands of plans at the close of 2026.
- Out-of-pocket limits are higher. The most a single person can be required to pay in a year for covered care climbs to $12,000, compared with $10,600 this year.
- Fewer immigrants qualify for help. From 2027, only three immigrant groups still qualify for subsidies: green card holders, Cuban-Haitian entrants, and people from Pacific nations covered by Compact of Free Association agreements. Refugees, asylees and many visa holders lose eligibility.
- Identity checks may add a step. Some HealthCare.gov shoppers may need to verify their identity before enrolling.
- Catastrophic plans are harder to get for people 30 and older, who once again need a hardship exemption.
State-level differences
Oregon has moved its shoppers off HealthCare.gov and onto its own platform, Explore Health. Virginia has added its own premium help for moderate-income households, and Rhode Island has set aside state funds to replace part of the lost federal support.
Why Auto-Renewal Could Cost You
If you do nothing, your marketplace may renew your plan automatically. That can be risky this year. If your insurer is leaving, the system may assign you a replacement plan that does not suit your doctors or budget. Even if your plan continues, its price and network may have changed, and a different plan could offer better value once subsidies are recalculated.
A Simple Shopping Checklist
We suggest working through these steps before the deadline:
- Read your renewal notice to see your 2027 premium before and after subsidies.
- Update your income estimate, since subsidies depend on expected household income.
- Compare at least three plans, looking at deductibles and out-of-pocket limits, not just monthly premiums.
- Check provider networks to make sure your doctors and preferred hospitals are included.
- Look at prescription coverage for any medicines you take regularly.
- Get free help from a certified marketplace navigator if the choices feel overwhelming.
A cheap monthly premium can hide a very high deductible, so think about how often you expect to use care before choosing.

Shop Early, Compare Carefully
The 2027 enrollment season is shorter, pricier and more complicated than recent years, but careful shopping can still find good value. Waiting until the last minute leaves little room to fix mistakes. Review your options now, compare plans side by side, and enroll by December 15 if you use HealthCare.gov.
