Which States Run Their Own Health Insurance Exchanges?

If you’re planning to enroll in health insurance for yourself or your family, it’s important to know who manages your state’s health insurance exchange—because it can affect how and when you enroll, what plan options are available, and what subsidies you may qualify for.

Under the Affordable Care Act (ACA), each state has the option to run its own health insurance marketplace, or to use the federally facilitated one through HealthCare.gov. As of 2025, some states operate fully state-run marketplaces with their own websites, deadlines, and plan offerings—while others rely on the federal government’s platform.

State-Based Marketplaces vs. Federally Facilitated Marketplaces

When the ACA was passed in 2010, it gave states the opportunity to build and manage their own health insurance exchanges. If a state declined, the federal government would step in and provide ACA-compliant plans through HealthCare.gov.

Today:

  • 20 states (plus Washington, D.C.) run their own marketplaces

  • 3 states use the federal platform for enrollment, but manage their own backend operations

  • The remaining 28 states use the federally facilitated marketplace

State-based marketplaces allow local governments more control over how plans are regulated, priced, and promoted. They can also set their own Open Enrollment Period (OEP) dates, which is helpful for residents who need more time to enroll.

States That Operate Their Own Health Insurance Exchanges (2025)

Here are the states that currently operate their own health insurance marketplaces, along with their platform names:

  • California – Covered California

  • Colorado – Connect for Health Colorado

  • Connecticut – Access Health CT

  • District of Columbia (D.C.) – DC Health Link

  • Idaho – Your Health Idaho

  • Maryland – Maryland Health Connection

  • Massachusetts – Massachusetts Health Connector

  • Minnesota – MNsure

  • Nevada – Nevada Health Link

  • New Jersey – Get Covered NJ

  • New York – NY State of Health

  • Pennsylvania – Pennie

  • Rhode Island – HealthSource RI

  • Vermont – Vermont Health Connect

  • Washington – Washington Healthplanfinder

Each of these states may offer unique plan choices, local insurer options, and extended enrollment deadlines beyond the federal window.

When Is Open Enrollment for ACA Plans in 2025?

The federal Open Enrollment Period for 2025 coverage is expected to run from November 1, 2024 through January 15, 2025. However, some state-run marketplaces set their own deadlines and may offer enrollment extensions.

What If You Miss Open Enrollment?

If you don’t enroll during the Open Enrollment Period and don’t qualify for a Special Enrollment Period (SEP), you may have to wait until the next OEP begins in late 2025. Here’s what happens if you don’t take action before the deadline.

Common SEP triggers include:

  • Loss of other coverage

  • Marriage or divorce

  • Birth or adoption of a child

  • Moving to a new ZIP code or state

 

Why Does It Matter Who Runs Your Marketplace?

If your state uses a state-based marketplace, your:

  • Enrollment dates may be longer or more flexible

  • Health insurance plan options may be broader or include regional carriers

  • Application process may take place on a different website (not HealthCare.gov)

ATTN Small Business Owners: 6 Reasons You Should Give Your Employees Insurance

Not convinced small business coverage is worth it?  Find out why we think it is.

1. It’s Cake.

As a business owner, your greatest currency is time. So the last thing you want is to waste that on looking for the right group plan.

When you hire an agent, you hire a full-time tour guide committed to navigating you through the selection process. With demographics, health concerns, and company size to consider, there are plenty of factors that must be included in your final decision.  An agent can explain the nitty-gritty details of selecting a plan that fits your company’s needs, instead of you spending an unbelievable amount of time trying to digest the vast sea of information. Consider them

2. Less Money (From You), Less Problems.

One of the biggest misconceptions about purchasing insurance is the hefty price tag that comes along with it.  And that can be true, if you go about the process in the wrong way. So we’re here to dispel that myth. 

Compared to individual health insurance, high costs of one insured person have a smaller effect in a larger pool – in other words, more people are paying to support the few who use the benefits of being covered to their full extent.

With comparison shopping, you avoid that. You are guaranteed to find the right plan at an affordable price.  You can contribute nothing to a plan – and it will still be beneficial for your employees. No risk is necessary.

It is important to keep in mind that you are not only the owner of your company; you are the owner of the plan selection. 

Checking out your options is a great place to start.

3. “I Want YOU To Buy Health Insurance!”

Little figurines of people passing money to each other from a pile down a line towrds a yellow piggy bank.
You end up saving money by offering employees group insurance. Employer contributions are tax-deductible, employer payroll taxes are reduced by 7.65% of employee contributions, and more!

If you still don’t believe in the affordability of group health coverage, consider this – it’s on Uncle Sam.  Two words for you: Tax. Benefits

Here are the tax savings you get by offering group health insurance:

  • Employer contributions are tax-deductible
  • Employer payroll taxes are reduced by 7.65% of employee contributions
  • Employer workers compensation premiums are reduced
  • No payroll taxes and workers compensation premiums on money used towards health benefits. 

And here are the tax savings your employees get by receiving group health insurance:

  • When employees buy health insurance on their own, they have to use post-tax dollars to buy it. They make money, the government taxes that money, and then they take the remaining amount to buy what they need.
  • When employees buy health insurance through a group plan, they pay for the insurance with pre-tax dollars. That can save them up to 30 to 45% on their health insurance premiums.

4. Healthy Employees = Happy Employees

You might not be able to buy the Beatles’ love, but you can buy your employees’.  

Studies show that small business health insurance plans increase employee loyalty and decrease turnover. There’s scientific proof that purchasing insurance for your employees can increase retention and aid in recruitment.  Mic drop. 

In all seriousness, health insurance is a big deal for both employees and job seekers.  For some, it’s even the deciding 

factor between job offers.

Healthy employees means less visits, less appointments, and less sick days. What this means is more productivity in the workplace.

Providing health insurance, despite not being a large corporate powerhouse, shows how much you value your potential and current employees.  Which – if you’re a good boss – is a lot.

5. And Happy Employees = Happy Boss

You can imagine that an employee with a burst appendix or an inflamed wisdom tooth might be a little distracted when calculating the day’s revenue.  But only a little.

Employees who aren’t provided health insurance have an increased likelihood of avoiding doctor appointments or hospital visits. In short, they have an increased likelihood of being unhealthy.

Additionally, healthy employees means less visits, less appointments, and less sick days.  If you focus on “saving money” at the cost of your employees’ health, we’re tellin’ ya, it’s just going to come back and bite you in the bottom. 

Or your bottom line.

6. The Gift That Keeps on Giving

Cobra isn’t just a snake.

The Consolidated Omnibus Budget Reconciliation Act (COBRA) is a health insurance program that allows an eligible employee and his or her dependents the continued benefits of health insurance coverage in the case that employee loses his or her job or experiences a reduction of work hours.
