The intuition behind an Association Health Plan is old and appealing: if small businesses band together, they should be able to buy health coverage the way a big company does. A single roofing contractor with four employees has no leverage. A thousand roofing contractors, pooled through their trade association, look — the theory goes — like one large employer, and large employers get better plans at better prices. Association Health Plans are the mechanism for that pooling, letting employers in a shared trade or region join together to sponsor a single group health plan.
The intuition is sound as far as it goes. The trouble is that "pool small businesses so they get treated like a big one" runs directly into the wall of laws built to protect the small-group and individual insurance markets, and the last decade of AHP policy is essentially the story of federal regulators, courts, and two administrations fighting over exactly how far that pooling should be allowed to go. More than most coverage arrangements, AHPs cannot be understood without their legal history, because the history is the current rulebook.
What an AHP is, and the ERISA question underneath it
An Association Health Plan is a group health plan sponsored by an association of employers rather than by a single employer. Its regulatory life is governed by a deceptively simple question under the Employee Retirement Income Security Act: is the association a bona fide "employer" that can sponsor a single ERISA plan on behalf of its members?
That question decides everything, because of how the ACA's market rules are structured. If an association's plan qualifies as a single large-group ERISA plan, it is regulated as large-group coverage — which means it escapes the requirements that bind the small-group and individual markets, including the essential-health-benefits mandate, the single risk pool, and adjusted community rating. If it does not qualify as a single large-group plan, then the coverage of each small member-employer is regulated according to that employer's own size, meaning a five-person member is subject to small-group rules regardless of the association wrapper. The entire value proposition of an aggressive AHP — big-group treatment for small-group members — depends on clearing the ERISA "bona fide employer" bar, and where that bar sits has been the crux of the fight.
Layered on top is the MEWA framework. An AHP that covers multiple unrelated employers is, almost by definition, a multiple employer welfare arrangement, and MEWAs carry their own regulatory weight. Congress amended ERISA in 1983 to let states regulate MEWAs — even self-funded ones — precisely because the early history of these multi-employer pools included insolvencies and outright fraud, with operators collecting premiums and vanishing before claims came due. That history shadows AHPs to this day and is a recurring theme in why regulators treat them warily.
The 2018 rule and the court that struck it down
For most of their history, whether an association counted as a bona fide employer was determined by a "facts and circumstances" test the Department of Labor developed through advisory opinions over many years. The test asked whether the association had a genuine purpose beyond selling insurance, whether its member-employers shared a real commonality of interest, and whether the employers controlled the plan. It was restrictive on purpose — it kept associations from being assembled out of thin air just to sell cheap, lightly regulated coverage.
In October 2017, an executive order directed the Department of Labor to make AHPs easier to form, and in June 2018 the Department issued a final rule doing exactly that. The 2018 rule loosened the bona-fide-employer test in three consequential ways. It allowed an association to form on the basis of geography alone — employers in the same state or metro area, in any line of business, could band together. It allowed associations to exist primarily to offer health coverage, rather than requiring a business purpose beyond benefits. And it allowed "working owners" — self-employed individuals with no employees — to count as both employers and employees for purposes of joining an AHP, opening the arrangements to sole proprietors. The stated goal was to expand affordable options for small businesses and the self-employed. The predictable effect, which the Department's own analysis acknowledged, was that healthier groups would peel off into AHPs that could rate by factors like age and industry and avoid essential-benefit requirements, pulling good risk out of the ACA-regulated markets and raising premiums for those left behind.
The rule did not survive. Eleven states and the District of Columbia sued, and on March 28, 2019, the U.S. District Court for the District of Columbia struck down the rule's core provisions. The court found that the Department had exceeded its authority under ERISA — that the 2018 rule stretched the meaning of "employer" past what the statute could bear, specifically by permitting geography-only associations, associations formed mainly to sell insurance, and the treatment of working owners with no employees as employers. The court called the rule an end-run around the ACA's consumer protections. The Department appealed, but the appeal stalled when administrations changed in early 2021, and the expanded rule never took full effect.
The 2024 rescission and where the law stands now
The 2018 rule then spent years in limbo — struck down in its key parts, under a paused appeal, technically still on the books. In December 2023 the Department of Labor proposed to rescind it entirely, and on April 29, 2024, it finalized that rescission. The final rule removed the 2018 regulation from the Code of Federal Regulations and returned AHP analysis to the pre-2018 sub-regulatory framework — the same facts-and-circumstances advisory-opinion approach that had governed for decades. Shortly after, on May 30, 2024, the D.C. Circuit dismissed the long-dormant appeal, closing the chapter. The Department noted it was not aware of any AHPs operating in reliance on the 2018 rule, so the practical disruption of the rescission was minimal; its main effect was to remove lingering uncertainty and firmly reestablish the older, stricter standard.
So as of this writing, an Association Health Plan is evaluated under the traditional three-part test. To be a bona fide employer group capable of sponsoring a single ERISA plan, an association generally must have a real business or organizational purpose unrelated to providing benefits; its member-employers must share a genuine commonality of interest, also unrelated to benefits, such as being in the same trade or industry; and the member-employers must exercise control over the plan. Associations that meet this test — long-standing trade groups sponsoring coverage for members in a shared industry, for example — can and do operate AHPs. Associations assembled merely to sell coverage, or spanning unrelated businesses linked only by geography, or built around self-employed individuals with no employees, generally cannot achieve single-large-group status, which means their small members remain subject to small-group rules.
Two forward-looking notes belong here. First, the Department declined in the 2024 rule to formally codify the pre-2018 guidance into regulation, and it signaled possible future rulemaking on MEWA oversight and on the definition of "employer" — so the framework, while currently settled, may yet be revisited through further guidance. Second, and more importantly for anyone relying on this, AHP policy has proven to be one of the most administration-dependent corners of health regulation: it was expanded by executive order and rule under one administration, struck down by a court, and rescinded under the next, all within about six years. It is entirely plausible that the direction reverses again. An employer or association evaluating an AHP should treat the current framework as the operative rule while recognizing that this is contested political ground, and should confirm the state of play at the time of decision rather than relying on any snapshot.
The two honest sides of the debate
Because AHPs sit at a genuine policy fault line, an objective account has to represent both cases fairly. Proponents argue that small businesses and the self-employed are poorly served by the small-group and individual markets — that they face high premiums, limited choice, and rating rules that force healthy small firms to subsidize others — and that pooling through associations is a legitimate way to give them the purchasing power and plan flexibility that larger employers already enjoy. On this view, expanded AHPs are a pro-competition, pro-access reform that lets small employers offer coverage they otherwise could not.
Critics respond that the mechanism by which AHPs lower costs for healthy groups is risk selection, not efficiency: an AHP that can rate by age and industry and skip essential-benefit requirements attracts healthier, cheaper groups, and every healthy group that leaves the ACA-regulated pool makes coverage more expensive for the sicker groups and individuals who remain. They add that the MEWA form's documented history of insolvency and fraud means loosely regulated multi-employer arrangements carry real risk to the very people they claim to help, and that the consumer protections AHPs sidestep — guaranteed essential benefits, community rating — exist for reasons legislatures decided were important. Both positions are internally coherent and rest on different judgments about the trade-off between access and market-wide stability. The courts, in striking down the 2018 rule, effectively sided with the market-protection view of what ERISA permits; the underlying policy argument continues regardless.
Who AHPs fit
Under the current framework, Association Health Plans are a viable option primarily for employers who are genuine members of a bona fide association — an established trade group or industry association that exists for real business reasons and whose members share a true commonality of interest. For a small business that belongs to such an association and can access coverage through it, an AHP may offer larger-group pricing, broader plan options, and the administrative benefits of pooled purchasing that would be unavailable to the business standing alone.
AHPs fit poorly, or are simply unavailable, where the only "association" on offer was clearly assembled to sell insurance, where members are linked by nothing but a desire for cheaper coverage, or where a self-employed individual with no employees is trying to buy in — the current rules generally foreclose those paths. And any AHP, even a legitimate one, warrants the same solvency scrutiny that the MEWA form's history demands: the coverage is only as sound as the arrangement backing it. For an employer weighing an AHP, the essential questions are whether the association is genuinely bona fide under the operative test, how the plan is funded and how financially sound it is, what consumer protections the coverage does and does not include, and — given how much this area moves — what the rules actually are at the moment of decision. Those are questions worth working through carefully with someone who tracks the regulatory state, because in this corner of the market more than any other, the ground has a habit of shifting underfoot.
