If you buy your own health insurance through HealthCare.gov, an important date is coming. Marketplace Open Enrollment for 2027 coverage starts on November 1 [1].
It is easy to let this slide, especially if your plan worked fine this year. But HealthCare.gov reminds people that prices and plans change every year, and your own situation may have changed too [2]. A new job, a raise, a child moving out, or a new medicine can all change which plan fits you best. A little planning now can help you avoid surprises in January.
Mark the Marketplace Open Enrollment dates
The dates are the first thing to get right, because missing them can leave a gap in coverage. HealthCare.gov lists these dates for 2027 coverage [1]:
- November 1: Open Enrollment starts.
- December 15: Last day to enroll or change plans for coverage that starts January 1.
- January 15: Open Enrollment ends. If you enroll or change plans December 16 through January 15, coverage starts February 1.
There is one more step people sometimes forget. Your coverage starts only after you pay your first premium [1]. For example, imagine you pick a plan on December 10 but forget to make the first payment. Your coverage would not begin on January 1 as planned. Setting a reminder to pay right after you enroll can prevent that.
Also check where to apply. How you apply depends on whether your state runs its own marketplace. For example, HealthCare.gov says that starting November 1, Oregon residents will use ExploreHealthOR.gov to enroll in 2027 coverage [3]. Use the state picker on that page to find the right website for where you live.
Update your application, even if you plan to keep your plan
This is the step that can matter most for your wallet. Marketplace savings are based on your expected income for the year you are applying for, not past years [2]. Skip the update, and you could end up with more savings than you should get. Or you could end up with less than you could get.
Getting too much help can catch up with you later. Say your savings were too high. HealthCare.gov says you have to pay back the difference when you file your federal taxes [2]. Getting too little help means you pay more each month than you need to. Either way, a quick update helps.
Watch for changes in your savings
It also helps to know that some savings have changed. HealthCare.gov says the additional savings available because of the COVID pandemic ended on December 31, 2025 [2]. If your costs looked different this year than in the past, that may be one reason. HealthCare.gov also notes that some people may get a letter saying they will not get the premium tax credit next year. Reasons can include updated income data or a need to send documents [2]. If you get a letter like this, do not ignore it. Read it carefully and respond by the date given.
Before you start, gather your best estimate of your household’s income for 2027. Note any changes in who lives with you or who is on your tax return. Then make a list of your doctors, medicines, and pharmacies. Having this ready can turn a long, stressful session into a shorter one.
Compare before you renew
Do you have Marketplace coverage? If you do nothing by December 15, you may be re-enrolled in your current plan or a similar one. If your insurer is not offering plans next year, you may be moved to a plan from a different insurer. But in some cases, you will not be automatically re-enrolled at all [2]. That is why it is wise to log in and look, even if you are happy where you are.
Understand the Marketplace metal levels
Plans on the Marketplace are grouped into “metal” levels: Bronze, Silver, Gold, and Platinum. The levels show how you and the plan split costs. On average, a Bronze plan pays about 60% and you pay about 40%. A Platinum plan pays about 90%, and you pay about 10% [5]. HealthCare.gov also says the metal levels have nothing to do with the quality of care you get [5].
There is one detail worth knowing if money is tight. Some people qualify for extra savings that lower deductibles, copays, and coinsurance. HealthCare.gov says these extra savings come only with a Silver plan [5]. If you think you might qualify, ask about this before you choose a different level.
When you compare plans, these questions can help you focus on what matters most:
- Are my doctors and hospitals still in the network?
- Are my medicines covered, and at what cost?
- What is the monthly premium, and what is the deductible?
- What will I pay for the visits and services I use most?
For example, imagine two plans with similar premiums. One covers your regular medicine with a low copay, and the other puts it in a higher-cost tier. Over a year, that difference can add up to much more than the premium gap.
Tru-Tips: Before you pick a plan, call your main doctor’s office and ask, “Will you be in network with this plan next year?” Office staff often know about network changes before they show up in online directories.
Get free Marketplace Open Enrollment help if you want it
You do not have to figure this out alone. People and groups in your community offer free help with applying, choosing a plan, and enrolling. You can find them on HealthCare.gov [4]. You can say: “I want to make sure my income estimate is right and my medicines are covered. Can you walk through it with me?”
What if you miss Open Enrollment? You may still be able to get coverage later in the year if you qualify for a Special Enrollment Period. These are tied to life events like moving, losing other coverage, getting married, or having a baby. You can also apply for Medicaid or the Children’s Health Insurance Program (CHIP) at any time [1].
