Open Enrollment Guide: What to Know for OEP 2027

Key takeaways

• The Open Enrollment Period (OEP) is the time each year when you can sign up for, renew, or change health insurance plans under the Affordable Care Act (ACA), also known as “Obamacare”. For most states, OEP runs from November 1, 2026, to January 15, 2027.
  • State-run marketplaces set slightly different dates, so it’s important to confirm your state’s timelines. To have coverage start on January 1, 2027, you must enroll and pay your first premium by December 15, 2026.
  • In most states, enrolling in January means your coverage won’t begin until February 1.
• OEP is your main chance each year to enroll in a new plan, renew your current coverage, or make changes unless you qualify for a Special Enrollment Period (SEP) due to major life events like moving, losing coverage, or having a baby.
• 2027 updates include:
  • Higher out-of-pocket limits: Health plans limit how much you may have to pay each year for covered, in-network care. In 2027, the upper limit for one person is $12,000, and $24,000 for a family. Note that your plan may have a lower limit. Monthly premiums do not count toward this amount.
  • Changes to who can get help paying for coverage: Some lawfully present immigrants will no longer qualify for federal help that lowers the cost of an ACA health plan. Eligibility depends on immigration status.

Intro: What is Open Enrollment?

Open Enrollment is the yearly period when you can sign up for health insurance or update your existing plan through the Health Insurance Marketplace (also called the Exchange).

This is your one guaranteed chance to review your options, compare plans, and choose coverage that fits your needs and budget. Outside of Open Enrollment, you can usually only change plans if you qualify for a Special Enrollment Period (SEP) due to major life events like getting married, moving, or losing other health coverage.

During OEP, you can:
• Choose a health plan that fits your household
• Review costs, coverage, and providers
• Lock in coverage for the upcoming year

Important dates for OEP 2027

Let’s look at the key dates to mark on your calendar for this health insurance Open Enrollment period:

• November 1, 2026: Open Enrollment begins in all states except Idaho, Connecticut and Massachusetts. Idaho OEP begins early on October 15, and Connecticut and Massachusetts both begin on October 23.
• December 15, 2026: Deadline to enroll for coverage that starts January 1, 2027 in most states, (you must also pay your first monthly premium by this date).
• January 15, 2027: Final deadline in most states (but not all) to enroll, renew, or change coverage for 2027.
• February 1, 2027: Coverage begins for people who enroll in January, in states that offer this option.

Note: Some state-run marketplaces have extended deadlines. For more information and to check your state’s dates, view this article on 2027 Open Enrollment dates by state.

Coverage options available during Open Enrollment

During Open Enrollment, you have different health insurance options. Understanding the types of coverage available can help you choose the plan that best fits your needs.

1. Employer-Sponsored Plans

What they are:
Health plans offered by your job, usually for full-time workers.

How it works:

• Sign up, renew, or make changes during your employer’s OEP.
• Choose from different plan types (like HMO, PPO, or high-deductible plans with HSAs).
• Select a coverage level: just you, you + spouse, or your whole family.

Why it matters:

• Your employer may pay part of the premium.
• Review deductibles, copays, and out-of-pocket limits to find your best option.

2. Individual and Family Plans

What they are:
Plans you buy yourself — either through the Marketplace or private insurers.

Coverage levels:
Every individual or family Marketplace plan falls into one of four “metal tiers”: Bronze, Silver, Gold, or Platinum. The tiers don’t describe the quality of care — all plans must cover the same set of essential health benefits under the ACA.

The tiers show how you and your insurance company share healthcare costs:

• Lower tiers (like Bronze) → lower monthly premiums, but higher costs when you actually get care.
• Higher tiers (like Platinum) → higher monthly premiums, but lower costs when you get care.

Think of the tiers as a trade-off: pay more each month vs. pay more when you need care.

Metal Tier Comparison

Tier	Monthly Premiums	Out-of-Pocket Costs	Best For	Extra Notes
Bronze	Lowest	Highest	People who are generally healthy, rarely visit the doctor, and want the lowest monthly payment.	Covers about 60% of healthcare costs on average; you pay about 40%. May come with high deductibles.
Silver	Moderate	Moderate	A balanced option for those who need occasional care.	Covers about 70% of costs on average. If your income qualifies (100–250% FPL), you may get cost-sharing reductions that lower your deductible, copays, and coinsurance — but only for Silver plans.
Gold	Higher	Lower	People who visit the doctor regularly, use prescriptions, or want more predictable costs.	Covers about 80% of costs on average. Deductibles and copays are usually lower than Bronze or Silver.
Platinum	Highest	Lowest	Individuals with frequent healthcare needs who want the most comprehensive coverage.	Covers about 90% of costs on average. Rare on the Marketplace, but best for those expecting high medical expenses.

Individual vs. Family:

• Individual: Covers one person
• Family: Covers two or more under one plan, with a combined deductible

Things to consider:

• High- vs. Low-Deductible Plans: High-deductible plans may pair with HSAs, which help you save for medical expenses tax-free — but it’s always best to check with a tax professional to be sure.
• Prescription Coverage: Check if your medications are included.
• Provider Networks: Make sure your doctors and hospitals are in-network to avoid extra costs.

Key Changes for OEP 2027

Two important changes taking effect for the 2027 Open Enrollment Period (OEP) may affect whether you qualify for financial help and how much you pay when you receive covered care:

Out-of-pocket limits are higher

• Each year, the federal government adjusts out-of-pocket limits as health insurance premiums change. An out-of-pocket limit places a cap on how much you may have to pay for covered, in-network care.
• For 2027, the highest limit increases from $10,600 to $12,000 for one person and from $21,200 to $24,000 for a family. This is the highest limit a plan may have — your plan may have a lower limit. The limit includes deductibles, copays, and coinsurance, but it does not include monthly premiums.
• Check your plan’s limit so you understand your possible costs for the year. When comparing plans, consider the limit along with the monthly premium, deductible, and coverage.

Eligibility for financial help is changing for some immigrants

• Starting in 2027, some lawfully present immigrants who previously received federal financial help with an ACA health plan will no longer qualify. They may still be able to enroll but may have to pay the full monthly premium.
• DACA recipients are covered by a different rule: They remain unable to enroll in Marketplace coverage or receive Marketplace financial help. Learn more about immigration status and Marketplace eligibility.

Important rules that will stay the same in 2027

These rules were already in place for 2026 and will continue for 2027.

Temporary extra financial help remains unavailable:

• The enhanced premium tax credits offered from 2021 through 2025 remain unavailable for 2027. Standard premium tax credits are still available. In general, your household income must be between 100% and 400% of the federal poverty level, and other eligibility rules apply.

Automatic re-enrollment continues

• You may be re-enrolled in your current plan or matched with another plan if your plan is no longer offered. Review your application and plan because your costs, doctors, prescriptions, and benefits may change. Learn more about automatic re-enrollment on Healthcare.gov.

The income-based Special Enrollment Period remains unavailable

• The monthly enrollment opportunity based only on household income at or below 150% of the federal poverty level remains unavailable in 2027. In most cases, you need a qualifying life event to enroll in or change Marketplace coverage outside Open Enrollment.

What to Review for 2027

Before renewing your coverage or choosing a new plan, review what is changing for 2027 and how those changes could affect your options, costs, and benefits.

Your plan choices and costs may change

• The health plans and insurance companies available in your area can change each year, along with premiums, deductibles, provider networks, and prescription coverage. Review your renewal notice and compare your 2027 options. If your current plan is ending, you may need to choose a different plan.

What to know about Special Enrollment Periods (SEPs)

SEPs allow for enrollment outside the main Open Enrollment Period or window due to qualifying life events such as:

• Losing other health insurance coverage
• Getting married or divorced
• Moving to a new state
• Having a baby or adopting a child

Note: The monthly income-only Special Enrollment Period is not available for 2027. Check the current rules before you try to enroll outside OEP, and be ready to provide proof of your qualifying life event.

How to Prepare for OEP 2027

Open Enrollment is your once-a-year opportunity to ensure your health coverage meets your needs and budget. Whether enrolling in an employer-sponsored plan or an individual/family Marketplace plan, remember to:

• Mark your calendar: Set reminders for November 1 and December 15.
• Review your current coverage: Consider what worked well, what didn’t, and whether your doctors and prescriptions are covered.
• Check your eligibility: Confirm subsidy eligibility and anticipated costs if enhanced subsidies expire.
• Gather your documents: Having your income info, household details, and Social Security numbers will make enrollment faster.
• Compare plans carefully: Don’t assume your costs will remain the same — shop around to find the best fit.
• Seek expert help: A licensed insurance agent can answer questions, guide plan comparisons, and help you enroll correctly.

Careful planning now can help you avoid surprises, manage your healthcare spending, and secure coverage that works for your household in 2027.
