An association health plan is one health plan shared by small businesses that belong to the same association, such as a trade group or a chamber of commerce. Instead of each business buying its own policy, the members' employees join one plan.

Association plans are still legal. A looser federal rule from 2018 that made them easier to start is gone, and nothing new has replaced it yet. A PEO (professional employer organization, an outside company that runs payroll, HR and benefits for small businesses) also lets small companies share a health plan, under partly different rules.

The short version

  • Could you join one? Only through an association that exists for more than insurance, whose members are truly connected, and whose members run the plan. Being in the same trade or state is no longer enough on its own.
  • Does it matter at your size? Mostly if you have 50 or fewer employees. That is where a shared plan can change which protections your staff get.
  • Is it cheaper? Sometimes, but the Labor Department says that is often because the plan covers less. No one has published a reliable savings figure.
  • Is it safe? Shared plans have a history of running out of money and leaving bills unpaid. Six written questions, below, show you how to check one.
  • Nothing new is law yet. A federal proposal and a House bill could change the rules. Neither is in force.

Could your business join one?

Picture a dental society or a restaurant association offering one plan to its members' employees. It can do that only if it passes three tests that the Labor Department has applied for decades:

  1. It exists for more than insurance, such as training, advocacy or trade standards.
  2. Its members are truly connected, for reasons that have nothing to do with the health plan.
  3. Its members run the plan, on paper and in practice.

A 2018 rule let businesses qualify just by sharing a trade or a state, and let owners with no employees join. A court threw those parts out in 2019, and the rule was withdrawn in 2024. So a self-employed owner with no staff has no route in today.

No public list says which associations pass. The Labor Department decides one at a time, in letters called advisory opinions. So ask the association (question 3 below).

What it means at your headcount

Federal law generally treats a company with 1 to 50 employees as a small group, and 51 or more as a large group. Under the Affordable Care Act, small-group insurance comes with protections: limits on how the insurer sets your price, and a required list of covered services, such as emergency care, prescription drugs and hospital stays. Large-group insurance has fewer of those protections.

Usually each business in an association plan still counts on its own, the federal health agency says. A 12-person restaurant stays a small group and keeps those protections. In rare cases, when the association itself counts as the employer, the plan counts all members' employees together as one large group, and your staff lose the small-group protections. The plan can tell you which applies (question 2 below).

  • 50 or fewer employees: make sure your staff keep the protections they have now.
  • 51 or more: you already buy large-group insurance. What matters is the price, what the plan covers, and whether it will still be there next year.

Is it cheaper?

Sometimes, but there is no reliable number. The Labor Department said in 2024 that association plans "are cheaper to purchase" because they can cover less, "but there is a significantly greater likelihood that they will cover less than expected or needed." Where state law allows, some plans also price your business on your own employees' health, so a business with older or sicker staff may not save at all.

A 12-person restaurant compares two quotes (made-up numbers)
Current small-group planAssociation plan quote
Monthly premium for 12 people$7,200$6,600
Prescription drugs coveredYesAsk
Hospital stays coveredYesAsk
Who pays the medical billsAn insurance companyAsk: an insurer, or the plan's own pot of money
Membership duesNoneAsk

Example with made-up numbers. Real quotes differ. The $600 gap means nothing until both columns cover the same things.

How a PEO's plan is different

A PEO shares the employer role with you, an arrangement called co-employment: it handles payroll, taxes and benefits paperwork, and you still hire people and direct the work. Your staff can join its health plan without you joining any association, and the PEO's plan does not have to pass the association tests. Otherwise the same questions apply: who pays the medical bills, what your state insurance department knows about the plan, and whether your staff keep small-group protections (questions 1 and 2 below).

A PEO also charges a fee on top of premiums. Across the industry, PEO fees typically run $40 to $160 per employee per month, or 2% to 12% of payroll, with most quotes at 3% to 5%. That is a general range, not any one provider's price. An association may charge membership dues instead.

How to check a plan: six questions, and what the answers mean

Shared plans "can provide valuable coverage," the Labor Department says, but "particularly self-funded" ones "have disproportionately suffered from financial mismanagement or abuse, leaving participants and providers with unpaid benefits and bills." That goes for association and PEO plans alike. Ask for written answers:

  1. "Is the plan fully insured or self-funded?" Fully insured means an insurance company pays the medical bills. Get its name and ask your state insurance department to confirm it is licensed in your state. Self-funded means the plan pays bills from its own pot of money, usually with a backup insurance policy for very large bills. That type has the worse track record: ask for the backup insurer's name, and ask the state insurance department about the plan and any complaints.
  2. "Does our coverage follow small-group or large-group rules?" Small-group means your staff keep the protections they have now. If they say large-group and you have 50 or fewer employees, ask which covered services and price limits your staff would lose.
  3. For an association: "How do you pass the three tests? Do you have a Labor Department advisory opinion?" An opinion letter is the strongest answer. A vague answer, or "we're waiting for the new rule," means it may not qualify today.
  4. "Can we see this year's Form M-1?" Shared plans must file this report with the Labor Department by March 1 each year. You can also look it up yourself in the Labor Department's online Form M-1 search, by plan or sponsor name. No recent report is a warning sign.
  5. "How is our rate set, and what can raise it at renewal?" If it depends on your own employees' claims, one bad year can raise your price.
  6. "What happens to our coverage if we leave, or the plan closes?" You want a firm end date and enough notice to find a replacement.

Then compare written quotes for your own employees, with the same benefits side by side. Some businesses come out ahead in a shared plan and some don't.

The detail, for your accountant or broker

Two legal names come up here. ERISA is the federal law that sets the rules for workplace benefit plans. MEWA (multiple employer welfare arrangement) is its name for a shared plan covering the employees of two or more unrelated companies.

What changed since 2018

In June 2018 the Labor Department loosened two of the three tests: an association's main purpose could be offering health coverage, and members could qualify by sharing a trade or a state or city area. It also let working owners with no staff join. Eleven states and Washington, D.C. sued. In March 2019, Judge John D. Bates of the federal trial court in Washington, D.C. cancelled the looser test and the working-owner part, calling the rule "clearly an end-run around the ACA." The appeal was paused in 2021. The department withdrew the whole rule as of July 1, 2024, saying that without the cancelled parts it "could not be operationalized." The older three tests apply again. The department's full wording of the connection test is "a commonality of interest and genuine organizational relationship unrelated to the provision of benefits," and members must control the plan "both in form and substance."

What may change next

A proposed rule. The Labor Department's proposal reached the White House office that reviews regulations on August 11, 2026, and was still there on October 21. The government's schedule lists it for November 2026, a target, not a promise. Its only public description says it "would establish criteria for an employer group or association to act as an 'employer'" and "sponsor an association health plan." The criteria are not public. A proposed rule is not a rule: the public gets time to comment, and a final rule can be challenged in court. The 2018 rule took five and a half months from proposal to final.

A House bill. The Lower Health Care Premiums for All Americans Act passed the House on December 17, 2025. The Senate has not acted on it, and it is not law. It would write association plan rules into ERISA itself. The association would have to have existed for at least two years for purposes other than health coverage, offer coverage to at least 51 employees in total and to all its members' employees, be controlled by its members (met if they hold at least 75% of board seats), and not tie membership to anyone's health. Where state law allows, a plan could set base rates by pooling all members' claims and then adjust each member's share for its "specific risk profile." Groups of at least 20 self-employed people could join together. The bill does not mention PEOs.

How PEO health plans are regulated

When a PEO's plan covers employees of two or more employers, the Labor Department says it "is a MEWA." Being your co-employer does not by itself make the PEO the employer for health-plan purposes; the department calls co-employer status "not determinative" under ERISA. Depending on the facts, the arrangement is either one plan for all clients, or a separate plan for each client company, with the PEO supplying the benefits much as an insurer would. If it is one fully insured plan, states can at least set how much money it must hold and take in to pay claims. If it is one self-funded plan, any state insurance law that doesn't conflict with ERISA can apply. If it is not one plan, states can regulate it as insurance.

The Labor Department has no rule on when a PEO counts as the employer for a health plan. In 2019 it called the topic "beyond the scope" of a rule that does set a PEO test, but only for shared 401(k)-style retirement plans. The 2024 withdrawal left that retirement-plan rule in place.

State PEO laws add a layer. In New York, a 2006 staff opinion of the insurance regulator said an insurer may treat a registered PEO as the employer when it buys a group health policy, and a 2005 opinion said a PEO may not self-fund health benefits for New York residents unless licensed as an insurer. Florida law says no licensed employee leasing company (its term for a PEO) "shall sponsor a plan of self-insurance for health benefits," except where Florida insurance law or ERISA permits. Our guides to PEO licensing by state and state PEO registration cover other states.

Both kinds of shared plan generally must file Form M-1 every year by March 1, and also 30 days before they start operating in a state.

Common questions

Are association health plans legal?

Yes. An association that passes the business-purpose, connection and control tests can still offer one. What ended in 2024 was the looser 2018 rule.

Can I join an association health plan if I'm self‑employed with no staff?

Not today. The 2018 route was thrown out in 2019 and withdrawn in 2024. A House bill would add a route for groups of at least 20 self-employed people, but only if it becomes law.

Are association health plans cheaper?

Sometimes, often because they cover less. No reliable savings figure exists, so compare written quotes for the same benefits.

What is a MEWA health plan?

A shared plan: one health plan covering employees of two or more unrelated companies. Most association plans and PEO plans that cover two or more clients are MEWAs, and states can regulate them.
