Choosing health insurance for the coming year can feel like one more complicated financial decision on an already crowded to-do list. Monthly premiums, deductibles, prescription costs, and provider networks can all affect how much a health plan actually costs. For people who purchase their own coverage, the annual Affordable Care Act (ACA) open enrollment period is an important opportunity to compare options and review available financial assistance.
Open enrollment for 2027 ACA Marketplace coverage begins in most states on November 1, 2026. The federal enrollment period runs through January 15, 2027, although some state-run marketplaces have different deadlines. During this window, eligible consumers can enroll in a new plan, renew their current coverage, or switch to another option.
This year’s enrollment period also comes with important financial considerations. Enhanced federal premium tax credits that helped reduce insurance costs in previous years expired at the end of 2025, and changes to federal assistance and tax rules may affect what some households pay for coverage.
Understanding the deadlines, reviewing updated plan prices, and checking financial assistance options can help consumers make a more informed decision for 2027.
When Is ACA Open Enrollment for 2027?
For people using HealthCare.gov, the federal Marketplace open enrollment period runs from November 1, 2026, through January 15, 2027.
However, the exact schedule depends on where you live. Some states operate their own health insurance marketplaces and set different enrollment deadlines.
Here are the key dates for the federal Marketplace:
- November 1, 2026: Open enrollment begins.
- December 15, 2026: Generally, the last day to select a plan for coverage starting January 1, 2027.
- January 1, 2027: Coverage generally begins for people who enroll by December 15 and pay their first premium.
- January 15, 2027: Open enrollment ends for HealthCare.gov.
- February 1, 2027: Coverage generally begins for people who enroll between December 16 and January 15 and pay their first premium.
These dates apply to the federal Marketplace. State-run exchanges may have different deadlines for enrollment and coverage start dates. For example, New Jersey’s Get Covered New Jersey marketplace has announced an open enrollment deadline of January 31, 2027.
Consumers should verify the dates for their state rather than assume that every marketplace follows the same schedule.
The official HealthCare.gov enrollment calendar provides current information about federal Marketplace deadlines and coverage start dates.
Who Can Enroll in ACA Marketplace Health Insurance?
ACA Marketplace plans are designed for people who need individual or family health insurance rather than coverage through an employer or another source.
Depending on their circumstances, people who may shop for Marketplace coverage include:
- Self-employed individuals and independent contractors
- Workers whose employers do not offer health insurance
- People between jobs or recently separated from employer-sponsored coverage
- Early retirees who are not yet eligible for Medicare
- Families purchasing their own health insurance
- People whose existing individual health insurance plan no longer meets their needs
Eligibility for Marketplace enrollment and eligibility for financial assistance are separate questions. A person may be able to purchase a Marketplace plan without qualifying for a federal premium tax credit.
Other factors, including access to affordable employer-sponsored insurance, household income, tax filing status, and immigration status, can affect eligibility for financial assistance.
People who qualify for Medicare generally should review Medicare coverage rules rather than assume that an ACA Marketplace plan is an appropriate alternative.
What Is Changing About ACA Financial Assistance in 2027?
Financial assistance is one of the most important issues for people shopping for health insurance this year.
For several years, enhanced premium tax credits helped make Marketplace coverage more affordable for many households. These expanded credits increased assistance for some existing recipients and allowed additional people to qualify based on their household income.
The enhanced credits expired at the end of 2025. As a result, many consumers have faced higher net premiums, and some households that previously received assistance may no longer qualify for the same level of support.
For 2027, consumers should not assume that the financial assistance they received in an earlier year will remain unchanged.
How ACA premium tax credits work
A premium tax credit is financial assistance that can reduce the monthly cost of an eligible health insurance plan purchased through the Marketplace.
The amount available generally depends on factors such as:
- Expected annual household income
- Household size and tax family composition
- The cost of the applicable benchmark health plan
- Eligibility for other qualifying health coverage
- Federal rules governing premium tax credits
Eligible consumers can generally choose to have advance payments of their estimated tax credit sent directly to their insurance company. This reduces the monthly premium they pay themselves.
Alternatively, eligible consumers may claim an available credit when filing their federal income tax return, subject to applicable requirements.
The amount of assistance is calculated individually. Two households living in the same area can receive different amounts of financial help because their incomes, family sizes, and other circumstances differ.
Can you still qualify for financial help in 2027?
Yes, some consumers can still qualify for federal premium tax credits, depending on their circumstances and the rules in effect for the 2027 coverage year.
However, the expiration of the enhanced credits means that assistance may be less generous than it was in 2025 or earlier years. Under the regular rules now applicable, eligibility and credit amounts depend on household income relative to the federal poverty level, benchmark plan costs, and other requirements.
Consumers should also check whether their state offers additional assistance. Some state-run marketplaces provide state-funded subsidies that can help offset insurance costs for eligible residents.
For example, New Jersey has announced that it will continue offering New Jersey Health Plan Savings to qualifying residents, with assistance available to eligible households with incomes up to 600% of the federal poverty level. The specific amount depends on individual circumstances and state program rules.
The best way to understand the assistance available to you is to complete an updated Marketplace application or use your state’s official plan comparison tool.
How to Compare ACA Health Insurance Plans for 2027
A plan with the lowest monthly premium is not necessarily the least expensive option over an entire year. Consumers should compare the premium alongside deductibles, copayments, prescription coverage, and the medical providers included in each plan.
Here are several factors worth reviewing before selecting coverage.
1. Monthly premiums
The premium is the amount you pay each month to maintain your insurance coverage.
When comparing plans, look at the estimated premium after any financial assistance for which you qualify. Also review the full premium so you understand the total cost of the insurance before assistance.
Premiums can vary significantly based on location, age, plan type, and other factors.
2. Deductibles and out-of-pocket costs
A deductible is the amount you generally must pay for covered services subject to the deductible before the plan begins paying its share.
Some services may be covered before you meet the deductible, depending on the plan.
Also compare copayments, coinsurance, and the annual out-of-pocket maximum. The out-of-pocket maximum limits what you pay for covered, in-network essential health benefits during the plan year, subject to applicable rules. It generally does not include monthly premiums or all possible expenses, such as costs for services that are not covered.
A plan with a higher deductible may have a lower premium, but it can expose you to greater expenses if you need medical care.
3. Prescription drug coverage
People who regularly take prescription medication should review each plan’s drug formulary, which is the list of medications covered by the plan.
Check whether your prescriptions are covered, which pricing tier applies, and whether the plan requires prior authorization or other approval before covering certain medications.
A difference in prescription coverage can have a meaningful impact on your yearly health care budget.
4. Doctors, hospitals, and provider networks
Before choosing a plan, verify that your preferred doctors, specialists, hospitals, and other health care providers participate in its network.
Out-of-network care can cost considerably more, and some plans may not cover routine out-of-network services except in certain circumstances.
If you are receiving ongoing treatment, check that your providers are included in the specific 2027 plan you are considering. A provider’s participation in one plan does not necessarily mean they participate in every plan offered by the same insurer.
5. Plan categories
ACA Marketplace plans are commonly organized into Bronze, Silver, Gold, and Platinum categories.
These categories describe how a plan and its members generally share the costs of covered care. They do not measure the quality of medical treatment.
- Bronze: Generally lower monthly premiums and higher costs when receiving care.
- Silver: Moderate premiums and cost-sharing; eligible consumers may qualify for additional cost-sharing reductions when selecting a qualifying Silver plan.
- Gold: Generally higher premiums but lower costs when receiving covered medical services.
- Platinum: Generally higher premiums and lower cost-sharing when covered care is needed.
The actual premiums and benefits vary by location and plan. Not every category is available in every area.
For eligible people with limited incomes, a Silver plan can be especially worth reviewing because cost-sharing reductions may lower deductibles and other out-of-pocket costs. These reductions are separate from premium tax credits and generally require enrollment in a qualifying Silver plan.
What Documents and Information Should You Gather?
Preparing before completing a Marketplace application can make the enrollment process easier.
You may need information about everyone in your household who is applying for coverage, including:
- Names, dates of birth, and household relationships
- Home address and ZIP code
- Social Security numbers, when applicable
- Immigration documents, when applicable
- Estimated household income for 2027
- Information about current health insurance coverage
- Details about employer-sponsored coverage that may be available
- Tax filing status and expected dependents
Income estimates deserve particular attention. Marketplace financial assistance is generally based on projected annual household income, not simply the amount you earned last year.
If your income varies because you work seasonally, freelance, operate a small business, or receive commissions, you may need to estimate your annual income using the information available to you.
You do not necessarily need every document in hand to begin researching plans. However, providing accurate information during the application process is important because the Marketplace may request additional documentation to verify certain details.
Why You Should Review Your Income Estimate During the Year
Your income can change after you enroll in a health insurance plan. A new job, additional freelance work, a change in work hours, marriage, or a change in household size may affect your eligibility for financial assistance.
If you receive advance premium tax credits, report relevant changes to the Marketplace promptly.
This is particularly important for 2027 coverage because federal rules have eliminated repayment caps on excess advance premium tax credits beginning with tax year 2026.
In practical terms, if you receive more advance assistance than you are ultimately entitled to receive, you may have to repay the entire excess amount when filing your federal tax return under the new rules.
For example, imagine that a household estimates its annual income at $35,000 and receives advance premium tax credits based on that estimate. If its actual income ends up substantially higher, the final tax credit may be smaller than the amount paid in advance. Depending on the household’s circumstances, the difference could result in an additional tax bill.
This is an illustrative example, not a calculation of any particular household’s eligibility.
Keeping your application current can help reduce the risk of receiving more assistance than you ultimately qualify for. Consumers should also keep Marketplace tax documents and follow IRS instructions when filing their returns.

What Happens If You Miss Open Enrollment?
Missing the annual enrollment deadline does not always mean you must wait until the following year to obtain health coverage.
Some people qualify for a Special Enrollment Period after certain life events. Qualifying circumstances may include:
- Losing qualifying health coverage
- Getting married
- Having or adopting a child
- Moving to a new area when applicable requirements are met
- Experiencing certain changes in household circumstances
The rules depend on the event and the person’s circumstances. Documentation may be required, and not every life change creates an enrollment opportunity.
Some people who lose Medicaid or Children’s Health Insurance Program (CHIP) coverage may also qualify for a Special Enrollment Period, depending on the situation.
Medicaid and CHIP enrollment is available throughout the year for people who qualify. These programs may offer free or low-cost coverage based on income, household circumstances, state rules, and other eligibility requirements.
If you miss open enrollment, review the official HealthCare.gov guide to coverage outside open enrollment to learn about potential enrollment options.
How to Get Started With ACA Open Enrollment
The Marketplace provides tools that allow consumers to research plans and review estimated costs before making a final selection.
A practical starting point is HealthCare.gov, where consumers in states using the federal platform can access the application, compare plans, and learn about available financial assistance.
If your state operates its own exchange, you may be directed to a separate official marketplace website. You can also use the federal government’s Marketplace information page to identify the appropriate resource for your state.
When comparing options, consider taking these steps:
- Review your current insurance plan, if you have one.
- Estimate your household income for 2027.
- Compare available plans and their estimated monthly premiums.
- Check deductibles, prescription coverage, provider networks, and out-of-pocket limits.
- Review any available premium tax credits or state-funded assistance.
- Confirm your enrollment deadline and the date your coverage will begin.
- Complete the enrollment process and pay your first premium as required by your insurer.
If you already have Marketplace coverage, do not assume that renewing the same plan is automatically the best choice. Benefits, premiums, provider networks, and financial assistance can change from one year to the next.
Reviewing your options annually gives you an opportunity to identify a plan that better fits your health care needs and household budget.
The Bottom Line on ACA Open Enrollment for 2027
ACA open enrollment is an important opportunity for individuals and families who purchase their own health insurance to compare coverage for the coming year. For most people using HealthCare.gov, the enrollment window runs from November 1, 2026, through January 15, 2027, with December 15 generally serving as the deadline for coverage beginning January 1.
This year’s financial assistance rules make it especially important to review updated premium estimates rather than rely on what you paid in previous years. Federal premium tax credits remain available to eligible consumers, and some states offer additional assistance. However, eligibility and the amount of financial help can vary.
Before selecting a plan, compare more than the monthly premium. Deductibles, prescriptions, provider networks, and potential out-of-pocket expenses all contribute to the overall cost of coverage.
Most importantly, use official Marketplace resources to check current deadlines, verify your options, and understand the financial assistance that may be available based on your circumstances. A little preparation can help you make a more informed health insurance decision for 2027.
