If you buy your own health insurance, the next Open Enrollment Period could be more important than usual.
The 2026 health insurance year already brought major changes for many Affordable Care Act Marketplace shoppers. The enhanced federal premium tax credits that had provided additional financial help for several years expired at the end of 2025, leaving some people with higher monthly premiums in 2026.
Now attention is turning toward 2027 health coverage.
Several rules affecting Marketplace enrollment and financial assistance are changing. Insurers are also proposing higher premiums in many states, although the final amount will vary by location and plan. An August 2026 analysis of proposed rates found a median proposed Marketplace premium increase of 15% for 2027 across insurers with publicly available filings.
That doesn’t mean your premium will automatically increase by 15%.
Your actual cost can depend on your age, location, household income, plan, available subsidies and other factors.
But it does mean that simply renewing the plan you had in 2026 may not be the smartest move.
Here’s what to know before shopping for 2027 coverage.
Important: Top Financial Programs is an independent information website, not a government agency or insurance company. We do not determine eligibility for health insurance, tax credits or other assistance. Marketplace rules and costs can change, so always verify current information through HealthCare.gov or your state’s official Marketplace before enrolling.
When Is 2027 Health Insurance Open Enrollment?
For people using the federally facilitated Marketplace, the Open Enrollment Period for 2027 coverage is scheduled to run from:
November 1, 2026, through December 15, 2026.
Coverage selected during that period generally begins January 1, 2027.
CMS finalized a change to the annual Open Enrollment Period beginning with the 2027 plan year. Under the new rules, Exchanges must have an enrollment period that starts no later than November 1 and ends no later than December 31, and the period cannot exceed nine calendar weeks. On the federal platform, the period is November 1 through December 15.
State-based Marketplaces can have different enrollment schedules within the federal parameters.
That distinction matters.
If you live in a state that operates its own Marketplace, don’t assume the federal HealthCare.gov calendar is your exact deadline.
Why 2027 Could Feel Different From 2026
There are several moving pieces.
The first is the expiration of the enhanced premium tax credits.
The second is the possibility of higher underlying premiums.
The third is changes to eligibility verification and enrollment procedures.
And the fourth is that consumers may need to pay closer attention to their income information and tax-credit eligibility.
The result is simple:
Don’t treat Open Enrollment as an automatic renewal.
Even if you liked your 2026 plan, the premium, deductible, provider network or prescription coverage could be different for 2027.
The Extra ACA Subsidies Are No Longer the Same
For several years, enhanced premium tax credits increased the amount of financial assistance available to many Marketplace consumers.
Those enhanced credits expired at the end of 2025.
That change was already reflected in 2026 coverage and has been one reason some consumers faced higher premiums this year. Covered California, for example, notes that the enhanced federal assistance ended December 31, 2025, although other financial help remains available for eligible consumers.
This is an important distinction:
The expiration of the enhanced credits does not mean all ACA subsidies disappeared.
Premium tax credits can still be available to eligible Marketplace shoppers under the applicable rules.
But the amount of assistance may be different from what someone received in previous years.
That means you shouldn’t assume that your 2026 subsidy will automatically be the same for 2027.
Your Income Matters More Than You May Think
When you apply for Marketplace coverage, you’ll provide information about your household and expected income.
That information can affect whether you qualify for financial assistance and how much assistance you receive.
For someone whose income changes during the year, this can create a tricky situation.
Imagine your household income was expected to be $45,000 when you enrolled.
Later, you picked up additional work and your household income became significantly higher.
If your application still reflects the old information, your financial assistance may not accurately reflect your circumstances.
That’s why updating your Marketplace application matters.
CMS has also finalized changes designed to strengthen income verification and protect against improper subsidy payments.
The lesson for consumers is straightforward:
Use your best current estimate and update your information when circumstances change.
Be Careful About Automatically Renewing Your Plan
Automatic renewal can be convenient.
You don’t have to start from scratch, and you don’t risk forgetting to enroll.
But convenience can come at a price.
Your insurer may change:
- Monthly premiums
- Deductibles
- Copayments
- Coinsurance
- Prescription coverage
- Provider networks
- Covered services
- Maximum out-of-pocket costs
Another plan may also become a better value.
That’s why Open Enrollment is an opportunity to shop, even if you’re happy with your current insurance company.
You don’t have to switch.
But you should at least compare.
Don’t Look Only at the Monthly Premium
A $250 monthly premium may sound better than a $350 premium.
But what happens when you actually need medical care?
The cheaper plan might have a much higher deductible.
It could also have higher copayments, narrower provider networks or different prescription coverage.
When comparing plans, look at the bigger picture.
Pay attention to:
Premium: What you pay every month to have coverage.
Deductible: What you generally pay for covered services before the plan begins paying according to its terms.
Copay: A set amount you may pay for certain covered services.
Coinsurance: A percentage of the cost you may pay for certain covered services.
Out-of-pocket maximum: The maximum amount you generally pay for covered in-network services during a plan year, subject to the plan’s rules.
A plan with a slightly higher monthly premium can sometimes be a better choice for someone who expects frequent medical care.
Someone who rarely visits the doctor may have different priorities.
There isn’t one universally “best” Marketplace plan.
The best fit depends on your household.
Check Whether Your Doctors Are Still in the Network
This is one of the easiest details to overlook.
You find a plan with an attractive premium.
You enroll.
Then you discover your preferred doctor doesn’t participate in the network.
Before selecting a plan, check the provider directory and, when possible, confirm directly with your doctor’s office.
Pay particular attention to:
- Primary care doctors
- Specialists
- Hospitals
- Urgent care centers
- Mental health providers
- Pediatricians
- Pharmacies
Provider directories can sometimes contain outdated information, so direct confirmation can be worthwhile if keeping a particular doctor is important to you.
Your Prescription Drugs Matter Too
A plan that works well for one person may be a terrible fit for another because of prescription coverage.
Before choosing a 2027 plan, make a list of the medications your household regularly takes.
Then check:
- Whether each medication is covered
- Which tier it falls into
- Your expected copayment or coinsurance
- Whether prior authorization is required
- Whether you must use a particular pharmacy
- Whether mail-order options are available
Don’t wait until after enrollment to discover that an important medication is treated differently under your new plan.
2027 Could Bring Higher Premiums in Some Areas
One of the biggest questions for consumers is how much Marketplace coverage will cost next year.
The answer depends heavily on where you live.
Insurers submit proposed rates, and those rates are reviewed before final premiums are established.
As of August 2026, the Peterson-KFF Health System Tracker reported a 15% median proposed premium increase for 2027 across 276 insurers with publicly available filings in all 50 states and Washington, D.C.
Again, that’s a median proposed increase, not a prediction that every consumer will see a 15% increase.
Some plans may increase substantially.
Others may increase less.
Some could remain relatively stable.
And shopping can make a difference.
Covered California, for example, recently announced a preliminary weighted average rate increase of 9.9% for 2027 while noting that many consumers could reduce the impact by comparing plans and switching to more affordable options.
Your own Marketplace will ultimately show the prices available to you.
Financial Assistance Can Still Matter
Even though the enhanced federal tax credits expired, financial assistance hasn’t disappeared entirely.
Eligible consumers may still qualify for premium tax credits under current rules.
Some states also provide additional financial assistance.
For example, several states have created their own subsidy programs to supplement federal assistance or provide additional help to certain residents. The details vary considerably by state.
That makes one piece of advice particularly important:
Don’t decide that Marketplace coverage is too expensive until you actually check your available options.
The price you see advertised isn’t necessarily the price you’ll pay.
Your household income, family size, age, location and other factors can affect the final cost.
2027 Also Brings New Enrollment and Verification Rules
Some of the changes for 2027 aren’t about premiums at all.
They’re about how Marketplace enrollment works.
CMS has finalized additional verification requirements for certain Special Enrollment Period applications on the federal Marketplace. The goal is to reduce improper enrollments and ensure people using a Special Enrollment Period actually meet the applicable requirements.
There are also changes affecting who can receive federal premium tax credits and cost-sharing reductions based on immigration status under the rules taking effect for plan years beginning in 2027.
These rules can be complicated.
If you’re unsure whether you qualify, don’t rely on a social media post or an advertisement promising that you’ll receive coverage.
Use the official Marketplace and provide the requested documentation.
What Should You Do Before November?
You don’t have to wait until Open Enrollment begins to prepare.
In fact, getting organized early can make the process much easier.
Start by gathering:
- Your expected 2027 household income
- Information about everyone who needs coverage
- Current insurance information
- Your doctors’ names
- Your prescription list
- Your preferred hospitals
- Your approximate monthly health-care spending
- Your current deductible and out-of-pocket costs
Then think about how you actually use health care.
Do you see a specialist frequently?
Do you take several prescriptions?
Are you expecting surgery or another major procedure?
Do you mostly need preventive care?
Are you primarily concerned about keeping the monthly premium low?
Your answers can help you decide what matters most when comparing plans.
A 2027 Open Enrollment Checklist
Use this checklist when you’re ready to shop:
- Check your state’s official Marketplace or HealthCare.gov.
- Confirm your Open Enrollment deadline.
- Review your current plan.
- Estimate your 2027 household income.
- Update your household information.
- Check whether you qualify for financial assistance.
- Compare monthly premiums.
- Compare deductibles.
- Compare out-of-pocket maximums.
- Check your doctors and hospitals.
- Check your prescription coverage.
- Review copays and coinsurance.
- Compare at least a few available plans.
- Confirm your enrollment after selecting a plan.
- Pay your first premium when required.
Don’t rush through the process.
A few extra minutes comparing plans could save you money or prevent an unpleasant surprise later.
What If Your Income Is Too High for Financial Assistance?
This is another area where assumptions can cause problems.
Some consumers automatically assume they won’t qualify for assistance because they believe their income is too high.
Others assume that everyone receives the same subsidy.
Neither is necessarily true.
Marketplace financial assistance depends on the rules in effect for the coverage year and your household circumstances.
If you don’t qualify for a premium tax credit, you may still be able to purchase Marketplace coverage.
You may also have other options, such as employer-sponsored insurance, Medicaid or other forms of coverage depending on your situation.
The important thing is to compare the choices available to you rather than relying on an old income number or last year’s eligibility.
What If Your 2027 Premium Is Much Higher?
Don’t panic when you see the first number.
First, compare your options.
A higher premium for your current plan doesn’t necessarily mean every available plan became equally expensive.
You may find:
- A different plan from the same insurer
- A different insurer with a lower premium
- A plan with a different deductible
- A plan that provides better value for your prescriptions
- A plan with a different provider network
But don’t switch solely because the premium is lower.
Check the complete plan details.
A $50 monthly savings could disappear quickly if the new plan doesn’t cover your preferred doctor or has significantly higher costs when you need care.
Where Should You Get Official Information?
Health insurance is one area where it’s especially important to verify information directly.
For Marketplace coverage, start with HealthCare.gov if your state uses the federal Marketplace.
Some states operate their own exchanges, so residents should use their state’s official Marketplace if applicable.
You can also find information about Medicaid and CHIP through official federal and state resources.
CMS publishes rules and guidance for the Marketplace, including the final 2027 standards that affect enrollment and eligibility.
Be cautious with websites or advertisements that make it sound like they are the government when they aren’t.
A private website can provide helpful educational information, but it should clearly identify itself as a private source.
Frequently Asked Questions
When is Open Enrollment for 2027 health insurance?
For the federal Marketplace, Open Enrollment for 2027 coverage is scheduled for November 1 through December 15, 2026. State-based Marketplaces may have their own enrollment schedules within the federal requirements.
Will health insurance premiums go up in 2027?
Some premiums are expected to increase, but the amount varies by insurer, plan and location. Proposed 2027 Marketplace rates show significant increases in many areas, but proposed rates aren’t the same as the final price every consumer will pay.
Are ACA subsidies still available in 2027?
Premium tax credits remain available under current rules for eligible Marketplace consumers, but the enhanced subsidies that had temporarily increased federal assistance expired at the end of 2025. Some states also offer their own assistance programs.
Should I automatically renew my 2026 health insurance plan?
Not necessarily. Even if you’re satisfied with your current plan, compare the 2027 premium, deductible, provider network, prescription coverage and out-of-pocket costs before deciding.
Can I change my health insurance during Open Enrollment?
Yes. Open Enrollment is the annual period when eligible consumers can select or change Marketplace coverage for the upcoming plan year.
What happens if I miss Open Enrollment?
You may have limited options unless you qualify for a Special Enrollment Period or another coverage pathway. Certain life events, such as losing qualifying health coverage, getting married or having a baby, can trigger a Special Enrollment Period under applicable rules.
Is HealthCare.gov the only place to buy ACA insurance?
No. Some states operate their own ACA Marketplaces. If your state has its own exchange, you may need to use that Marketplace to enroll and access applicable financial assistance.
The Bottom Line
The 2027 health insurance enrollment season is worth taking seriously.
Consumers are entering it after a major change to federal premium assistance, and many insurers are proposing higher rates for next year. At the same time, Marketplace enrollment rules and verification procedures are changing.
That may sound complicated.
For most shoppers, the practical takeaway is actually pretty simple:
Don’t blindly renew.
Review your income.
Check your financial assistance.
Compare plans.
Look at your doctors and prescriptions.
Pay attention to the deductible and out-of-pocket maximum, not just the monthly premium.
And most importantly, know your enrollment deadline.
For consumers using HealthCare.gov, the 2027 Open Enrollment Period begins November 1, 2026, and ends December 15, 2026.
Health insurance can be expensive, but taking the time to compare your options may help you find coverage that fits your health needs and your budget better in 2027.
