When Is Open Enrollment for Health Insurance 2027? Dates, Deadlines, and How to Get the Best Plan

ACA Open Enrollment 2027 opens November 1, 2026 and closes January 15, 2027. That is the window when anyone can enroll in, change, or drop a marketplace health insurance plan. Miss it and you typically wait until open enrollment 2028. This guide covers the exact 2027 open enrollment dates, how to estimate your ACA subsidy, which plan tier to choose, and the five mistakes that cost people thousands every November.

What Is ACA Open Enrollment 2027?

The Affordable Care Act (ACA) marketplace -- also called the Exchange or Healthcare.gov -- is where individuals and families who do not get coverage through an employer or a government program shop for health insurance. ACA open enrollment is the annual window when anyone can enroll in, change, or drop a marketplace plan without needing a special qualifying reason.

For 2027 coverage, open enrollment runs from November 1, 2026 through January 15, 2027. Outside of that window, you can only enroll if you experience a qualifying life event such as losing job-based coverage, getting married, or having a baby.

The ACA marketplace is available to most US residents who are not eligible for Medicare, Medicaid, or coverage through an employer. This includes self-employed workers, 1099 contractors, gig workers, early retirees, people between jobs, and anyone whose employer does not offer affordable group coverage.

Open Enrollment Deadlines for 2027 Coverage

2027 Open Enrollment Deadlines by State

Almost everyone starts at the same time. Open enrollment for 2027 coverage begins November 1, 2026 in every state except three: Idaho opens early on October 15, and Connecticut and Massachusetts open on October 23.

The close date is where it varies. If your state runs its own exchange, your deadline is set by that exchange. If your state uses HealthCare.gov — that includes Florida, Texas, Ohio, Tennessee, and most of the South and Midwest — you follow the federal date: January 15, 2027. Most state exchanges land on the same day; a handful run later, and two close earlier.

Last verified July 28, 2026. Deadlines are still being confirmed by several states for 2027. If your enrollment depends on an exact date, call us at (954) 825-1009 and we will check your state's exchange with you before you file.

Florida residents note: Florida uses the federal marketplace at Healthcare.gov, not a state exchange. The deadlines above apply to all Florida counties including Miami-Dade, Broward, Palm Beach, and Hillsborough. Some states with their own exchanges extend open enrollment past January 15; Florida follows the HealthCare.gov calendar.

Open Enrollment 2027 in Florida

Florida uses HealthCare.gov. There is no separate Florida exchange and no Florida-only deadline. Open enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027, exactly like Texas, Georgia and the other thirty-odd HealthCare.gov states. Enroll by December 15, 2026 and your coverage starts January 1. Enroll between December 16 and January 15 and it starts February 1.

Three things make Florida different in practice, and none of them are about the calendar:

• Florida has not expanded Medicaid. That leaves a coverage gap: adults earning below the poverty line often do not qualify for Medicaid or for marketplace subsidies. If your income estimate lands near the line, where you land matters enormously, and it is worth getting the estimate right before you enroll rather than after.
• Networks are narrower than the plan names suggest. South Florida has a lot of plans that look like PPOs on the summary page and behave like HMOs at the specialist's front desk. Check your doctors individually, by name, in the plan's own directory — not the carrier's general one.
• A large share of Florida enrollees are self-employed. Owner-operators, contractors, stylists, rideshare drivers and small-business owners estimate income for the year ahead rather than reading it off a W-2. Estimate it too low and you repay the difference at tax time; too high and you overpay every month. Our ACA subsidy calculator gives you the number before you commit to it.

Understanding Your ACA Subsidy in 2027

This is where most people leave money on the table. ACA subsidies officially called Premium Tax Credits are based on your Modified Adjusted Gross Income (MAGI) relative to the Federal Poverty Level (FPL).

For 2027, the Federal Poverty Level figures published in early 2026 apply. As a rough benchmark, 400% of the FPL is roughly $63,000 for a single adult and about $130,000 for a family of four — earn under those amounts and you are likely eligible for a premium tax credit. With the enhanced credits expired, there is now a hard cutoff at 400% of the FPL: earn even slightly above it and you generally receive no subsidy (the "subsidy cliff"). This is exactly why a careful income estimate is worth getting right before you enroll.

"We routinely find clients who have been paying full price for years because they assumed they made too much to qualify. In most cases, they didn't."

Bronze, Silver, Gold, Platinum Which Tier?

ACA plans come in four metal tiers that reflect the split between what the insurer pays vs. what you pay out-of-pocket:

• Bronze: Lowest premiums, highest deductibles. Good if you're healthy and rarely use care.
• Silver: Mid-range premiums and deductibles. The only tier eligible for Cost-Sharing Reductions (CSR), which can dramatically lower out-of-pocket costs if you qualify.
• Gold: Higher premiums, lower deductibles. Good if you have regular prescriptions or predictable medical needs.
• Platinum: Highest premiums, lowest out-of-pocket. Rarely the best value unless you have very high expected utilization.

The Silver trap: Many people choose Bronze to save on premiums, not realizing that Cost-Sharing Reductions (CSR) -- which can cut your deductible from $8,000 to under $1,000 -- are only available on Silver plans. If your income qualifies for CSR, a Silver plan almost always gives you better total value than Bronze even if the monthly premium is higher.

A quick rule: if your income is between 100% and 250% of the Federal Poverty Level, enroll in a Silver plan first. Then compare the actual out-of-pocket costs against Gold. The monthly premium difference is usually much smaller than the deductible difference.

The Narrow Network Trap

This is the most common costly mistake we see in South Florida. A plan that looks affordable on the surface may have a network so narrow that your primary care doctor, your specialist, and your preferred hospital are all out-of-network. In Miami-Dade and Broward counties, network adequacy varies dramatically between carriers -- and the carriers with the lowest premiums are often the ones with the tightest networks.

Before you enroll in any plan, verify:

1. Your primary care physician is in-network
2. Your specialists are in-network
3. Your preferred hospital system (Jackson Health, Baptist Health, Cleveland Clinic Florida, HCA Florida, etc.) is in-network
4. Your current prescriptions are on the plan formulary at a reasonable tier
5. If you travel frequently or have family in other states, check whether the plan has out-of-network emergency coverage

You can verify a plan's network before enrolling by using the "Find Care" tool on each carrier's website or by calling us directly. We check this for every client at no charge.

The 5 Mistakes We See Every November

Mistake 1: Waiting Until January to Enroll

Open Enrollment opens November 1 for a reason. The plans, networks, and pricing change every year. Waiting until January means you miss the December 15 deadline for January 1 coverage -- leaving you without insurance for the first month of 2027. That gap can mean paying full price for any prescriptions, doctor visits, or medical events in January.

Mistake 2: Auto-Renewing Without Reviewing Your Plan

If you do not actively choose a plan during open enrollment, Healthcare.gov will auto-renew you into your current plan -- or a similar one if yours is discontinued. The problem: carriers change networks, formularies, and premiums every year. The plan that saved you money last year may now have a higher deductible, a different network, or a better subsidy-optimized alternative you are missing. Spending 20 minutes reviewing during open enrollment can save you $1,000 or more over the year.

Mistake 3: Guessing on Your Projected Income

Your ACA subsidy is based on your projected income for 2027, not your 2026 income. If you are self-employed, a 1099 worker, freelancer, or expecting any major income change, estimate carefully. Under-estimating your income means you receive more subsidy upfront -- but you will have to repay the difference when you file your taxes. Over-estimating is the safer direction. A licensed broker can help you find the right projection without leaving money on the table.

Mistake 4: Choosing the Cheapest Premium Instead of the Best Value

The lowest monthly premium is almost never the cheapest plan once you factor in total cost. A $50/month cheaper Bronze plan can easily come with a $2,000 to $4,000 higher deductible -- meaning you pay far more the first time you actually need care. Compare the full picture: premium, deductible, out-of-pocket maximum, copays for your usage patterns, and whether your medications are covered at a reasonable formulary tier.

Mistake 5: Not Working With a Licensed Broker

Working with a licensed brokerage like VS Health Benefits costs you nothing. Brokers are paid a flat commission by the carrier -- your premium is identical whether you use a broker or enroll directly. But a broker compares every available plan in your zip code, verifies your doctors are in-network, runs your subsidy estimate, flags CSR eligibility, and helps you avoid the four mistakes above. There is genuinely no reason not to use one.

Who Qualifies for ACA Marketplace Plans in 2027?

Most US residents are eligible to enroll in an ACA marketplace plan during open enrollment. You qualify if you:

• Live in the United States and are a US citizen, national, or lawfully present immigrant
• Are not currently incarcerated
• Are not eligible for Medicare (generally under age 65 unless you have a qualifying disability)
• Do not have access to affordable employer-sponsored coverage that meets minimum value standards

You do not need to be employed to qualify. Self-employed workers, 1099 contractors, freelancers, gig workers, students, early retirees, and people between jobs can all enroll. Income is only relevant for determining your subsidy amount -- there is no income minimum to enroll in a marketplace plan at full price. Not sure what you would pay? Try our ACA subsidy calculator or ask us to run it for you.

Special Enrollment Periods: What to Do If You Miss Open Enrollment

If you miss the January 15, 2027 open enrollment deadline, you can still enroll in an ACA marketplace plan if you experience a qualifying life event within the past 60 days. Most SEPs give you a 60-day window to enroll after the event occurs. More common questions are answered in our open enrollment 2027 FAQ.

Qualifying life events include:

• Losing job-based, COBRA, student, or other health coverage
• Getting married or entering a domestic partnership
• Getting divorced or legally separated (if you lose coverage)
• Having a baby, adopting a child, or placing a child for adoption or foster care
• Moving to a new zip code or county -- even within Florida
• Gaining US citizenship, national status, or lawful presence
• Leaving incarceration
• Becoming newly eligible for premium tax credits because your income changed

If you are not sure whether your situation qualifies, call us. We help people evaluate SEP eligibility every week and can tell you within minutes whether you have a qualifying event.

ACA Open Enrollment 2027 FAQ

When is ACA open enrollment 2027?

ACA open enrollment for 2027 coverage opens November 1, 2026 and closes January 15, 2027. To have coverage begin January 1, 2027, you must enroll by December 15, 2026. Plans enrolled December 16, 2026 through January 15, 2027 take effect February 1, 2027.

When does open enrollment start for 2027 health insurance?

Open enrollment for 2027 ACA health insurance starts November 1, 2026. That is the first day Healthcare.gov opens for 2027 plan shopping, comparison, and enrollment. Most people should aim to enroll in November to give themselves the most time to review plans before the December 15 cutoff for January 1 coverage.

What is the deadline for ACA open enrollment 2027?

The absolute final deadline is January 15, 2027. The more important deadline is December 15, 2026 -- that is the cutoff for January 1 coverage. If you miss December 15 you can still enroll through January 15, but your coverage will not start until February 1.

What if I miss open enrollment 2027?

If you miss the January 15 deadline, you generally cannot enroll in an ACA marketplace plan until open enrollment 2028 -- unless you experience a qualifying life event such as losing other coverage, getting married, or having a baby. Some people who fall below the Medicaid income threshold may qualify for Medicaid year-round regardless of open enrollment.

How do I estimate my ACA subsidy for 2027?

Your subsidy is based on your projected 2027 Modified Adjusted Gross Income (MAGI) relative to the Federal Poverty Level (FPL). A licensed broker can calculate your specific estimate for free in about five minutes. You can also use the subsidy calculator at Healthcare.gov as a starting point, but a broker will catch deductions and situations the calculator may miss -- particularly if you are self-employed.

Do ACA subsidies continue in 2027?

Yes, but at the original ACA levels, not the enhanced levels. The enhanced premium tax credits from 2021–2025 expired December 31, 2025, so for both 2026 and 2027 coverage, subsidies follow the original ACA rules: premium tax credits are available to households earning between 100% and 400% of the Federal Poverty Level, with a hard cutoff at 400% (the "subsidy cliff"). Congress has considered restoring the enhanced credits — the House passed a three-year extension (HR 1834) in January 2026 — but no extension has become law as of this update. Because subsidy amounts are smaller than in recent years, it is worth having a licensed broker run your exact 2027 estimate before you enroll.

Can I get ACA coverage outside of open enrollment 2027?

Yes, but only through a Special Enrollment Period triggered by a qualifying life event -- losing coverage, getting married, having a baby, or moving. Outside of a qualifying event, you must wait for open enrollment. Some people also qualify for Medicaid or CHIP year-round based on income, regardless of open enrollment.

Is ACA open enrollment the same as Obamacare open enrollment?

Yes. ACA, Obamacare, the marketplace, and the exchange all refer to the same health insurance program. Open enrollment 2027 refers to the annual enrollment window for plans purchased on this marketplace -- November 1, 2026 through January 15, 2027.

Is open enrollment for health insurance 2027 different in Florida?

No. Florida uses HealthCare.gov, so open enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027, the same as every other HealthCare.gov state. Enroll by December 15, 2026 for coverage that starts January 1, 2027.

I missed open enrollment by one day. Can I still enroll?

Not in a standard marketplace plan, unless you qualify for a special enrollment period. Missing January 15 by a day is treated the same as missing it by a month. However, a qualifying life event in the previous 60 days, such as losing coverage, moving, marrying or having a baby, reopens a 60-day enrollment window. Medicaid and CHIP also enroll year-round if you qualify.

What happens if I miss open enrollment at work?

Employer open enrollment is set by your employer's plan year, not the ACA calendar, so missing it is a separate problem. You generally wait until the next plan year unless you have a qualifying life event. You may still be able to buy an individual marketplace plan during ACA open enrollment, though you will not get a subsidy if your employer offered you affordable coverage that meets minimum value.

When does open enrollment start for 2027?

November 1, 2026 in every state except three. Idaho opens earliest on October 15, 2026, and Connecticut and Massachusetts open on October 23, 2026. Every state closes on a different schedule; HealthCare.gov states close January 15, 2027.
