ACA Marketplace Plans

The Health Insurance Marketplace, created by the Affordable Care Act, is where individuals and families buy their own major medical coverage. Every plan sold there covers the same ten essential health benefits, and none can turn you down or charge you more for a pre-existing condition.
What varies is the price, and that depends heavily on your income. This page explains how the pricing works, when you can enroll, and what changed recently.

What changed for 2026 and 2027

The enhanced premium tax credits introduced in 2021 expired on 31 December 2025 and have not been renewed. Two things follow from that.
First, the subsidy cliff has returned. Households earning above 400 percent of the federal poverty level now receive no premium tax credit at all. Under the enhanced rules there was no upper limit.
Second, average premiums rose sharply for 2026, and carriers have priced the change fully into 2027 rates. If you last shopped for a Marketplace plan before 2026, what you remember paying is unlikely to match what you would pay now.

How Marketplace Pricing Works

You may see two different kinds of help with cost. They work differently and have different eligibility.
Type of helpWhat it doesWho qualifies
Premium tax creditLowers your monthly premium. Can be applied in advance so you pay less each monthHouseholds between 100 and 400 percent of the federal poverty level
Cost-sharing reductionsLowers your deductible, copays, and out-of-pocket maximumLower-income households, and only on Silver plans
The premium tax credit is calculated against the second-lowest-cost Silver plan in your area, known as the benchmark. That benchmark changes every year, so your credit can move even when your income has not.

The cliff is a hard edge, not a slope

At 400 percent of the federal poverty level the premium tax credit stops entirely. A household a few hundred dollars over the line receives nothing, while one just under it may receive a substantial credit. If your income is near that threshold, the estimate you give the Marketplace matters a great deal, and getting it wrong can mean owing money back at tax time.

When You Can Enroll

There are two ways in. Open Enrollment happens once a year and is open to everyone. A Special Enrollment Period opens after certain life events and can happen at any time of year.
Key dateWhat happensNotes
1 November 2026Open Enrollment begins for 2027 coverageIdaho opens 15 October. Connecticut and Massachusetts open 23 October
15 December 2026Deadline to enroll for coverage starting 1 January 2027This date holds in every state and with every carrier
Closing dateCurrently unsettledSee the note below

The closing date is genuinely unresolved right now

A 2025 CMS rule shortened Open Enrollment on the federal platform to 1 November through 15 December, starting with the 2027 plan year. That rule was challenged, a court ruled on it in June 2026, and the Department of Health and Human Services filed an appeal in July 2026. Until the appeal is decided, it is not certain whether the window closes on 15 December or continues to 15 January as in previous years.
States that run their own Marketplaces set their own dates within federal limits, so the answer also depends on where you live. Rather than rely on a date published anywhere, including here, confirm the current deadline for your state before you plan around it.

What Every Marketplace Plan Covers

These protections apply to every plan on the Marketplace, at every price point.
• The ten essential health benefits, including hospitalization, prescriptions, maternity care, and mental health treatment.
• No pre-existing condition exclusions. You cannot be refused, charged more, or have a condition carved out.
• Preventive care at no cost to you, including screenings and annual visits, before any deductible.
• An annual cap on out-of-pocket spending. Once you reach it, the plan pays the rest of your covered in-network care that year.
• No annual or lifetime dollar limits on essential health benefits.
• Dependent coverage to age 26, whether or not the child lives with you or is a student.

Choosing Between Plans

Since every plan covers the same benefits, the differences that matter are cost structure, network, and drug coverage.
What to checkWhy it mattersHow to check it
Total yearly costA low premium with a high deductible can cost more overall than the reverseAdd the annual premium to what you realistically expect to spend on care
Whether your doctors are in networkNetworks differ between plans from the same carrier, and several carriers narrowed networks recentlyCheck each plan’s provider directory, and confirm with the practice directly
Your prescriptions and their tierThe same drug can sit at different tiers with very different costsLook up each medication on the plan’s formulary
Whether you qualify for cost-sharing reductionsIf you do, a Silver plan may beat a Gold plan on both premium and out-of-pocket costsThis depends on income relative to the federal poverty level
Whether the plan is HSA-eligibleLets you set aside pre-tax money for medical costsPlan documents state this, most often on Bronze plans

If You Already Have a Marketplace Plan

Marketplace coverage renews automatically if you do nothing, and that is usually the more expensive option. Two things go stale.
Your plan changes underneath you. Premiums, deductibles, networks, and drug lists are all reset each year. The plan with the same name may not be the same plan.
Your income estimate carries forward unchanged. The Marketplace keeps whatever figure you last reported. If your income rose, your credit has been overstated all year and you may owe it back at tax time. If it fell, you have been paying more than you needed to.
Updating your income and comparing plans during Open Enrollment takes very little time and is the single most valuable thing most households can do.

If the Marketplace Is Not the Right Fit

With the subsidy cliff back in place, households above 400 percent of the federal poverty level pay full price on the Marketplace. That makes comparing alternatives worthwhile in a way it was not a couple of years ago.
