ACA open enrollment for 2027 coverage begins November 1, 2026. The median proposed premium increase for individual-market plans is about 15%, insurers are leaving marketplaces in 24 states and some plans end December 31. To keep coverage starting January 1, enroll or change plans by December 15.
Open enrollment is the one window each year when most people can choose or change an Affordable Care Act marketplace plan. This year the stakes are higher than usual. Prices are rising, subsidies are changing and hundreds of thousands of people will have to pick a new plan whether they want to or not. The Spectrum Post explains money and policy changes in plain terms, and this guide is for anyone who buys their own health insurance.
When Does ACA Open Enrollment Start and End?
Open enrollment begins on November 1 in most states. According to HealthCare.gov, December 15 is the last day to enroll or change plans for coverage that starts January 1. Open enrollment ends January 15.
If you enroll between December 16 and January 15, coverage starts February 1. Miss January 15 and you can enroll only if you qualify for a Special Enrollment Period, which usually requires a life event such as moving, losing other coverage, getting married or having a baby.
State-run marketplaces can set their own dates. Oregon, for example, is moving to a new state-run platform called Explore Health, with window shopping starting October 15 and enrollment starting November 1. Check your state's exchange for its exact calendar.
How Much Are Premiums Going Up?
For many people, noticeably. Analysts at healthinsurance.org report that the median proposed rate increase for individual-market plans is about 15% for 2027. Weighted average increases range from under 7% in states like Vermont, New York, Iowa and Utah to 29% in Arizona.
These are proposed rates. Final numbers appear in your renewal notice, and that is the number that matters. Compare the new price with last year's, but also compare it with what other plans cost for the same coverage level.
A rate increase does not hit everyone equally. Premium subsidies are tied to the cost of a benchmark plan, which is the second-lowest-cost Silver plan in your area. When the benchmark rises, the subsidy usually rises too, so many subsidized enrollees are partly shielded. People without subsidies, including those who buy off the exchange, bear the full increase.
Why Are Insurers Leaving the Marketplace?
Insurers are leaving because the business is harder to run profitably. The same source reports that insurers are exiting marketplaces in 24 states, and that hundreds of thousands of enrollees have plans ending December 31, 2026. A handful of states will add a new carrier, including California, Colorado, Georgia, Indiana, Minnesota, Ohio and Texas, one each.
If your insurer is leaving, you will receive a notice. Do not ignore it. The exchange may assign you a replacement plan through automatic renewal, but that plan is chosen by an algorithm, not by your needs.
The practical risk is losing a doctor or a prescription. A new insurer may have a different network and a different list of covered drugs. Check both before you accept a replacement.
What Else Changes for 2027 Coverage?
Several limits and rules shift. The maximum out-of-pocket limit for an individual rises to $12,000 in 2027 from $10,600 in 2026. Health savings account contribution limits rise to $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750.
Federal subsidy eligibility also narrows. Starting with 2027 coverage, subsidies are limited to lawful permanent residents, Cuban and Haitian entrants and migrants from the Compacts of Free Association. Refugees, asylees, Temporary Protected Status holders and most people on work or student visas no longer qualify.
The enhanced federal subsidies that made premiums cheaper for many households expired at the end of 2025. Some states are stepping in. Virginia starts a state savings program on November 1 for residents with incomes between 138% and 250% of the federal poverty level, and Rhode Island has set aside $19 million to partly replace the lost enhancements.
Should You Let Your Plan Renew Automatically?
Usually not. Auto-renewal is convenient, but it keeps you in a plan that may no longer be your best option. Premiums, deductibles, networks and drug lists all change from year to year.
Healthinsurance.org's advice is blunt: don't rely on auto-renewal. If your insurer is leaving or your premium is jumping, a few minutes of shopping can save real money. Compare your after-subsidy premium, not the sticker price, since subsidies change what you actually pay.
Look at the plan's metal tier, too. A cheaper Bronze plan has lower premiums but higher costs when you use care. A Silver plan costs more each month but often pays more when you need it, and Silver is the tier tied to extra cost-sharing help for some lower-income enrollees.
What Does a Higher Out-of-Pocket Limit Mean in Practice?
The out-of-pocket maximum is the most you can be required to pay for covered, in-network care in a plan year. Once you reach it, the plan pays the rest. For 2027 that cap is $12,000 for an individual, up from $10,600.
Most people never reach it. The limit matters in a bad year, such as a hospital stay or a major diagnosis, when it works as your worst-case number. A plan with a lower premium but a $12,000 cap can leave a household exposed if savings are thin.
A fair way to compare plans is to add up two scenarios. In a healthy year, you pay the premiums plus a few routine visits. In a bad year, you pay the premiums plus the out-of-pocket maximum. If the bad-year number would break your budget, a plan with a higher premium and lower cost-sharing may be the safer choice.
How Do You Compare Plans Step by Step?
A simple checklist keeps the process manageable. Work through these steps before the deadline.
- Log in early and update your income estimate for 2027, since it determines your subsidy.
- List the doctors, hospitals and prescriptions you use, and check each plan's network and drug list.
- Compare the premium, deductible and out-of-pocket maximum together, not just the premium.
- Estimate your likely care costs for the year and add them to the premium.
- Check whether any state subsidy or program applies to you.
- Enroll by December 15 for January 1 coverage, and pay the first premium to activate it.
Income reporting deserves extra attention if you earn money outside a regular paycheck. Our explainer on what side hustle income means for your taxes shows how irregular income complicates the estimate, and a bad estimate can mean repaying part of your subsidy at tax time.
What If You Are Self-Employed or Between Jobs?
Marketplace plans are often the main option for freelancers, gig workers and people between jobs. The rules above apply to you, and the income estimate matters most. Estimate conservatively and update it during the year if your earnings change.
Health savings accounts can help in a high-deductible plan. HSA contributions reduce household income for subsidy purposes, according to healthinsurance.org, which can raise subsidy eligibility. Our guide to retirement savings limits covers other tax-advantaged accounts to consider alongside it.
If you are close to 65, make sure you understand the handoff to Medicare. Our report on Medicare open enrollment for 2027 explains that separate process and its own deadlines.
How Does Insurance Pricing Fit Into the Bigger Squeeze?
Health insurance is one of several household insurance costs rising at once. Our look at why home insurance premiums keep climbing in 2026 shows a similar pattern of rising costs and shrinking choices.
For a typical household, the combination matters more than any single bill. A 15% increase on a premium of several hundred dollars a month is a real budget line. Planning for it now beats discovering it in January.
It also helps to know your fallback. If a plan becomes unaffordable, ask about a lower metal tier, a different insurer or a state program. Do not drop coverage without a plan, since going uninsured leaves you exposed to the full cost of a surprise bill.
Keep records, too. Save a copy of your final plan confirmation, your premium payment receipt and your income estimate. If a billing or eligibility question comes up later in the year, those three documents settle most disputes quickly and spare you a long call with the exchange.
The Bottom Line for Open Enrollment
This year's open enrollment rewards people who look before they renew. Prices are rising, insurers are leaving and rules are changing for some immigrants and some income groups. A short comparison session now is worth more than a hurried one in mid-December.
At The Spectrum Post, our editors will keep following changes as final rates and state rules arrive. Your next step is to find your current plan's renewal notice, note your premium and deductible, and block an hour before December 15 to compare alternatives.
