Who can buy from the Health Insurance Marketplace?

Almost any US resident not enrolled in Medicare and not incarcerated. You must be a US citizen, US national, or lawfully present immigrant. There is no income minimum to buy a Marketplace plan, though subsidy eligibility depends on income, household size, and whether your employer offers affordable coverage. Lawfully present immigrants qualify for subsidies with no waiting period.

Is the Marketplace the same as Obamacare?

The Marketplace was created by the Affordable Care Act (the law nicknamed Obamacare). They are not identical — the Marketplace is the shopping platform, Obamacare is the law. But when someone says they have an Obamacare plan, they almost always mean a plan bought on the Marketplace.

How do I shop on the Marketplace?

Go to HealthCare.gov (or your state Marketplace if you live in CA, NY, MA, CO, CT, DC, ID, KY, ME, MD, MN, NV, NJ, NM, PA, RI, VT, VA, or WA). Create an account, enter household income and family size, and the site shows every plan available in your zip code with subsidies applied. You can filter by metal tier, monthly premium, deductible, or insurer. A licensed agent can do all of this with you for free.

What is a Special Enrollment Period?

A 60-day window outside the annual Open Enrollment when you can enroll in a Marketplace plan because of a qualifying life event — losing other coverage, getting married, having a baby, moving, becoming a citizen, or a significant income change. Documentation is usually required. Medicaid and CHIP are open year-round in every state with no SEP needed.

What if I miss Open Enrollment and have no qualifying life event?

Check Medicaid and CHIP first — they accept applications year-round. If your income is too high for those, you can buy a short-term health plan, but be careful: short-term plans do not have to cover pre-existing conditions or essential benefits. A licensed agent can review your options before you commit.

How are subsidies calculated?

The premium tax credit is based on your estimated annual household income compared to the Federal Poverty Level, the cost of the second-lowest-cost Silver plan in your area, and what the law says is an affordable percentage of your income. The subsidy is paid directly to the insurer each month, so you see a lower premium on your bill. At tax time, the IRS reconciles what you received with what your actual income turned out to be.

What is the difference between a navigator, a broker, and an agent?

Navigators are federally funded helpers who walk you through the application but cannot recommend specific plans. Brokers and agents are state-licensed professionals paid by the insurance company, not by you. Both are free to the consumer. Agents typically represent one or a few insurers; brokers can represent many. Nexus Insurance partners with licensed brokers and agents.

Can I switch plans during the year?

Generally only if you have a qualifying life event during a Special Enrollment Period. If your income changes substantially, you can update it on the Marketplace and your subsidy adjusts, but you usually stay on the same plan until the next Open Enrollment.

Marketplace Health Insurance 2026: How to Shop & Save

The Health Insurance Marketplace explained: who can buy, how subsidies work, plan tiers, enrollment dates, and how to find the right plan in your state.

Last updated: May 10, 2026

The Health Insurance Marketplace is where most Americans without employer coverage buy private health insurance. It is also one of the most misunderstood pieces of the US healthcare system — partly because the law that created it is called several different names (ACA, Obamacare, the Affordable Care Act) and partly because every state seems to do it a little differently.

This guide walks through what the Marketplace is, who can use it, how the math actually works for real households, and the difference between getting help from a navigator, an agent, and a broker. We will keep it concrete — what you do, in what order, and what to watch out for.

For 2026 coverage, more than 24 million people are expected to enroll, continuing the record growth seen in recent years according to CMS data. The enhanced subsidies that made coverage affordable for middle-income families remain in place. If you have not looked recently because the numbers did not work, the numbers have changed.

What is the Health Insurance Marketplace?

The Marketplace is an online platform where private insurance companies sell health plans regulated by the federal government. Created by the Affordable Care Act of 2010, it lets consumers compare plans side-by-side in a single place, with subsidies automatically applied to the prices they see.

The federal site is HealthCare.gov. It serves 30+ states. The other 19 jurisdictions run their own state Marketplaces with different brand names — Covered California, NY State of Health, Massachusetts Health Connector, Pennie (Pennsylvania), and so on. The shopping experience is similar; the plan options differ.

Every plan on the Marketplace is required to cover the ten essential health benefits:

Ambulatory patient services (doctor visits)
Emergency services
Hospitalization
Maternity and newborn care
Mental health and substance abuse treatment
Prescription drugs
Rehabilitative services
Laboratory services
Preventive and wellness services
Pediatric services, including dental and vision

Plans cannot deny you for pre-existing conditions, cannot charge women more than men, and cannot impose annual or lifetime limits on essential benefits. These rules apply to every Marketplace plan, regardless of insurer or state.

Who can buy from the Marketplace?

You can buy a Marketplace plan if you:

Live in the United States
Are a US citizen, US national, or lawfully present immigrant
Are not currently incarcerated
Are not enrolled in Medicare

There is no income minimum to buy. There is no upper income limit either — wealthy households can buy Marketplace plans, they just do not get subsidies. The Marketplace is for individuals and families who do not have affordable coverage through an employer or a public program.

Subsidy eligibility

Two kinds of subsidies are available, and they have different rules:

Premium Tax Credit (PTC): Reduces your monthly premium. Available to households earning roughly 100% to 400% of the Federal Poverty Level (FPL), and through 2025 (with strong likelihood of extension) anyone above 400% FPL whose premium would otherwise exceed 8.5% of income. The PTC is paid directly to your insurer each month.

Cost-Sharing Reduction (CSR): Lowers your deductible, copays, and out-of-pocket maximum. Available only if you pick a Silver plan and your income is below 250% FPL. Can take a $7,000 deductible down to $700 or less.

According to the Kaiser Family Foundation (KFF), about 92% of Marketplace enrollees in 2024 received a premium tax credit. The vast majority of people who shop the Marketplace do not pay the sticker price.

Immigrants and the Marketplace

Lawfully present immigrants — green card holders, refugees, asylees, valid visa holders, and several other categories — can buy Marketplace plans and qualify for subsidies with no waiting period. This is different from Medicaid, which generally requires a five-year wait.

If you are undocumented, you cannot buy on the federal Marketplace. Some states (California, New York, Colorado, Washington) have separate state-funded coverage options. Mixed-status families can apply on the Marketplace — only the eligible members are enrolled, and the household’s information is not shared with immigration enforcement. Learn more.

How to shop on the Marketplace

Here is the actual process, step by step:

1. Pick the right site. If you live in one of the 19 states with its own Marketplace, you must use that state’s site. Everyone else uses HealthCare.gov. The site auto-detects this when you enter your zip code.

2. Create an account. You will need a working email address. Make a note of your password — you will use this account every year.

3. Start an application. The site asks for everyone in your tax household, even if they will not be on the insurance. It asks for estimated 2026 household income. Be realistic — over-estimating costs you in subsidies; under-estimating can mean paying some back at tax time.

4. Verify identity. The Marketplace cross-checks SSNs and immigration documents with federal databases. Most applicants are verified instantly.

5. See plans. Once eligibility is confirmed, you see every plan available in your zip code with the subsidies applied. Prices shown are what you would actually pay.

6. Compare. Use the filters — metal tier, monthly premium, deductible, insurer, plan type (HMO/PPO/EPO). For each plan you are considering, check that your doctors and prescriptions are in network.

7. Enroll. Pick a plan, confirm your selection, pay your first premium directly to the insurer. Coverage starts the following month (or January 1 if you enrolled by December 15).

A licensed agent can do steps 2 through 7 with you in one phone call, free of charge.

Marketplace plan categories: Bronze, Silver, Gold, and Platinum

Every Marketplace plan is sorted into one of four metal tiers based on how the costs are split between you and the insurance company when you use care:

Tier	Plan pays	You pay	Best for
Bronze	~60%	~40%	Low premium, high deductible — fine for healthy people, risky for chronic conditions
Silver	~70%	~30%	The sweet spot for most enrollees; only tier with cost-sharing reductions
Gold	~80%	~20%	Higher premium, lower out-of-pocket — good for frequent care users
Platinum	~90%	~10%	Highest premium, lowest out-of-pocket — usually only worth it with heavy medical needs

A Catastrophic tier also exists for people under 30 or with hardship exemptions. Very low premium, very high deductible, mainly emergency-only coverage.

The metal tier says nothing about the quality of the network or the doctors. A Bronze Aetna plan covers the same essential benefits as a Platinum Aetna plan. The difference is when you pay — every month, or when you get sick.

Smart move for income-eligible enrollees: Look at Silver plans first if your income is under 250% FPL. The cost-sharing reductions make Silver effectively better than Gold for the same out-of-pocket exposure, often for a lower premium.

Subsidies are the reason most enrollees pay so much less than the sticker price. Two ways to take the Premium Tax Credit:

Advance Premium Tax Credit (APTC): Estimate your annual income when you enroll, and the IRS sends the subsidy directly to your insurer each month. Your monthly bill is lower. This is what most people choose.

Year-end credit: Pay the full premium each month, then claim the entire credit on your tax return. Better if your income is unpredictable and you do not want to risk owing money back.

The PTC is calculated using a formula tied to:

Your modified adjusted gross income (MAGI) for the year
The Federal Poverty Level for your household size
The benchmark plan — the second-lowest-cost Silver plan in your area
The applicable percentage — how much the law expects you to pay toward premiums

Reconciliation happens at tax time on IRS Form 8962. If you earned more than you estimated, you may owe some PTC back. If you earned less, you get extra credit. Always report income changes to the Marketplace as soon as they happen to keep things accurate. The IRS has a free guide.

Worried about owing money at tax time? A licensed agent can help you set your income estimate carefully and update it during the year. Talk to an agent.

Special Enrollment Periods: life events that open a new window

Open Enrollment runs roughly November 1 through January 15 for most states. Outside that window, you cannot enroll unless you have a qualifying life event triggering a Special Enrollment Period.

Common SEP triggers:

Loss of health coverage — job loss, COBRA ending, aging off a parent’s plan, losing Medicaid eligibility, losing student health coverage
Changes in household — marriage, divorce, birth, adoption, custody change, death of someone on your plan
Changes in residence — moving to a new state, county, or zip code with different plan options
Changes in eligibility — becoming a US citizen, being released from incarceration, a significant income change
Other — gaining membership in a federally recognized tribe, errors during your application, exceptional circumstances

You typically have 60 days from the event to enroll, and you usually need documentation. Some SEPs allow plan changes for current enrollees; others only allow new enrollments.

The Marketplace also has a year-round low-income SEP for households under 150% FPL. And Medicaid and CHIP are open year-round in every state with no SEP needed.

State Marketplaces vs. the Federal Marketplace

Most states (30+) use HealthCare.gov as their Marketplace. The federal government runs the technology, but plans are sold by private insurers based in each state.

19 jurisdictions run their own Marketplaces with their own websites, customer service, and sometimes different enrollment periods or extra benefits:

California — Covered California
New York — NY State of Health
Massachusetts — Health Connector
Pennsylvania — Pennie
New Jersey — Get Covered New Jersey
Colorado — Connect for Health Colorado
Washington — Washington Healthplanfinder
Maryland — Maryland Health Connection
Connecticut — Access Health CT
Minnesota — MNsure
Nevada — Nevada Health Link
Idaho — Your Health Idaho
Rhode Island — HealthSource RI
Vermont — Vermont Health Connect
Kentucky — kynect
Maine — CoverMe.gov
Virginia — Virginia’s Insurance Marketplace
New Mexico — beWellnm
Washington DC — DC Health Link

If you live in one of these, you must use the state site — HealthCare.gov will redirect you. The application process is similar, but plan offerings and prices are different.

What if I miss Open Enrollment?

You have three options:

Option 1: Qualify for a Special Enrollment Period. Review the life-event list above. Anything in the past 60 days that could plausibly fit is worth a call to the Marketplace.

Option 2: Apply for Medicaid or CHIP. No deadline. Income limits vary by state. In Medicaid expansion states, adults under 138% FPL qualify with no asset test. CHIP covers children up to ~250% FPL in most states.

Option 3: Consider a short-term plan as a stopgap. These are not ACA plans — they can deny coverage for pre-existing conditions, can have annual limits, and are not required to cover essential benefits. Use them only as a bridge to next Open Enrollment, and only if you understand the trade-offs.

If you find yourself uninsured between enrollment periods, do not let it sit. The longer you go without coverage, the bigger the risk of a single ER visit becoming a financial catastrophe. A licensed agent can review your options in 15 minutes.

Marketplace vs. private off-exchange insurance

You can also buy private health insurance directly from an insurer, outside the Marketplace. This is called off-exchange. The plans are often the exact same products sold on the Marketplace, with two important differences:

1. No subsidies off-exchange. Premium tax credits and cost-sharing reductions are only available for plans purchased through the Marketplace. If you qualify for subsidies, going off-exchange means paying full price.

2. Same consumer protections. Off-exchange ACA plans must still cover essential benefits, cannot deny for pre-existing conditions, and cannot impose annual or lifetime limits.

When does off-exchange make sense? Usually only when (a) you do not qualify for subsidies, and (b) you want a plan or insurer not offered on the Marketplace in your area. For most enrollees, on-exchange wins because of subsidies.

Getting help: navigators, brokers, and licensed agents

You have free help available no matter how you apply.

Navigators are federally funded community-based helpers. They are trained on the Marketplace and can walk you through the application, but they cannot recommend specific plans. They serve everyone, especially underserved populations. Find a navigator on HealthCare.gov.

Brokers and agents are state-licensed insurance professionals. They are paid commissions by the insurance companies — not by you. There is no consumer cost to working with one. They can recommend specific plans, compare options across insurers, and stay with you through the year for renewals, claims questions, and Special Enrollment Periods.

The practical difference: a navigator gets you across the finish line on the application. A licensed agent gets you across the finish line and picks up the phone in March when your prescription is denied.
