Health Insurance Marketplace 2026: How to Compare Plans, Check Subsidies, and Enroll

The Health Insurance Marketplace is the Affordable Care Act (ACA) exchange, HealthCare.gov or your state's exchange, where people without employer coverage shop for health plans, compare prices, and learn whether they qualify for credits. In 2026, subsidies follow the ACA rules: credits are available between 100% and 400% of the federal poverty level, and nothing is available above that cap.

This guide walks through the 2026 rules step by step: the subsidy cliff, the metal tiers, how to compare plans on total cost, and the enrollment deadlines. For more plain-language money guides, see Problem Solved on YouTube.

• Open Enrollment runs November 1 to January 15 in most states. A qualifying life event opens a 60-day Special Enrollment Period.
• Metal tiers describe cost-sharing: Bronze covers about 60% of average costs, Silver 70%, Gold 80%, Platinum 90%.

What the Health Insurance Marketplace Is

The Health Insurance Marketplace is the government-run exchange created by the Affordable Care Act (ACA) where individuals and families buy health insurance when they do not get coverage through an employer. Most states use HealthCare.gov, while some states run their own exchanges.

Every Marketplace plan must cover the same essential health benefits, including hospitalization, prescription drugs, preventive care, emergency services, maternity care, and mental health services. Plans cannot deny you coverage or charge you more because of a pre-existing condition.

The 2026 Subsidy Cliff: What Changed

From 2021 through 2025, temporarily enhanced premium tax credits made Marketplace coverage cheaper and removed the income cap on subsidies. Those enhanced credits expired on December 31, 2025. For 2026, the original ACA subsidy structure is back, including its hard income cliff.

Under the 2026 rules, premium tax credits are available only to households earning between 100% and 400% of the federal poverty level. Earn one dollar above 400% of the poverty level, about $62,600 for a single person for 2026 coverage, and your premium tax credit is zero for the year. KFF reported that the expiration pushed average out-of-pocket premiums about 58% higher in 2026, and the Urban Institute projected about 4.8 million people would become uninsured.

The size of a credit is tied to the benchmark plan, the second-lowest-cost Silver plan in your area. The credit covers the difference between the benchmark premium and the share of income the law expects you to contribute.

Metal Tiers: Bronze, Silver, Gold, and Platinum

Metal tiers do not describe quality of care. They describe how the total cost of covered care is split between you and the insurer, on average. Bronze plans cover about 60% of average costs, Silver plans about 70%, Gold plans about 80%, and Platinum plans about 90%.

Bronze plans have the lowest monthly premiums and the highest costs when you use care. Silver plans are the most popular tier, and the only tier offering cost-sharing reductions, extra help with deductibles and copays for households earning roughly 100% to 250% of the federal poverty level. Gold plans charge more per month but much less at the doctor's office. Platinum plans have the highest premiums and the lowest cost-sharing.

How to Compare Plans: Total Cost, Not Just the Premium

The cheapest monthly premium is not always the cheapest plan. Compare the total yearly cost: twelve months of premiums plus the deductible, copays, coinsurance, and the out-of-pocket maximum, based on the care you realistically expect to use. For example, if Plan A charges $50 less per month than Plan B but has a $2,000 higher deductible, Plan A costs $600 less in premiums over the year, yet one hospital visit could leave you paying far more than $600 extra before coverage kicks in.

Next, check the network. Marketplace plans generally pay far less, or nothing at all, for out-of-network care. Confirm that your doctors, hospital, and pharmacy are in the network before you enroll, and check the drug formulary if you take regular prescriptions.

How to Check Your Subsidy

Subsidies are based on Modified Adjusted Gross Income (MAGI). Modified Adjusted Gross Income (MAGI) is your adjusted gross income plus certain additions, such as tax-exempt interest and non-taxable Social Security benefits. The Marketplace asks you to estimate your income for the coverage year, then pays an advance premium tax credit directly to your insurer to lower your monthly bill.

Estimate carefully. If your actual income ends up higher than your estimate, you may have to repay some or all of the advance credit when you file taxes on Form 8962. If it ends up lower, you may receive an additional credit. Update your application during the year if your income, household size, or address changes.

If your income is below 100% of the federal poverty level, you generally do not qualify for premium tax credits. In states that expanded Medicaid, Medicaid covers adults up to 138% of the poverty level. In states that did not expand Medicaid, some people fall into a coverage gap: too low for credits and ineligible for Medicaid.

Enrollment Windows and Deadlines

Open Enrollment runs from November 1 to January 15 in most states. In HealthCare.gov states, enrolling by December 15 gives you coverage starting January 1; enrolling later gives you coverage starting February 1. Some state exchanges set different dates.

Outside Open Enrollment, you can enroll only during a Special Enrollment Period. A Special Enrollment Period is a 60-day window that opens after a qualifying life event, such as losing job-based coverage, getting married, having a baby, moving to a new coverage area, or losing Medicaid or CHIP coverage.

Frequently Asked Questions

Who can use the Health Insurance Marketplace?

U.S. residents and people lawfully present in the United States can use the Marketplace if they lack access to affordable employer coverage and are not eligible for Medicare or Medicaid. You enroll through HealthCare.gov or your state's own exchange.

How much does Marketplace insurance cost in 2026?

The Centers for Medicare and Medicaid Services (CMS) reported that the average 2026 Marketplace premium was $619 per month before tax credits and $178 per month after credits. Your price depends on income, age, location, household size, and plan.

What happens if my income goes over 400% of the federal poverty level?

In 2026, the premium tax credit drops to zero above 400% of the federal poverty level. If you received advance credits on a lower estimate, you may have to repay some or all of them at tax time, so update your income estimate promptly.

Can I change my Marketplace plan in the middle of the year?

Generally no. You can change plans during Open Enrollment or during a 60-day Special Enrollment Period after a qualifying life event, such as losing job-based coverage, getting married, having a baby, or moving to a new coverage area.
