Association Health Plans in 2026: What Small Employers Need to Know

2026-09-18 • 8 min read

An association health plan lets small employers band together to buy coverage as one large group, but a 2024 federal rule change made it much harder for an association to qualify. Here is the current test and what it means before you join one.

Quick Answer (as of 2026): An association health plan lets a group of small employers band together and buy health coverage as if they were one large employer. A 2024 Department of Labor rule reversed a 2018 expansion, so an association now has to pass a stricter three-part test to qualify. Most loosely formed buying groups no longer meet the bar.

A group of small business owners in the same trade association hears about a way to combine their headcounts and buy health coverage the way a 500-person company does. It sounds like an easy win: bigger group, better rates, less exposure to a single bad claim year. For a few years, from 2018 to 2024, a federal rule made that path easier than it had been in decades. That rule is gone now.

The Department of Labor rescinded the expanded association health plan rule effective June 29, 2024, according to the DOL's own final rule notice, and the requirements for a group of employers to legally act as one employer under federal law are back to a stricter standard that predates 2018. Here is what that standard actually requires, and what it means for a small employer considering one of these plans today.

What Is an Association Health Plan?

An association health plan, often shortened to AHP, is a group health plan that a qualifying association of employers sponsors on behalf of its member businesses, treated under federal law as a single ERISA-covered "employer" plan instead of many small separate plans. When an association qualifies, its combined membership can be underwritten and priced as one large group, which can mean more stable rates and fewer of the small-group market rules that apply to any one member business shopping alone. The Employee Retirement Income Security Act, known as ERISA, is the federal law that decides whether a group of employers can be treated this way, and the Department of Labor is the agency that interprets and enforces that standard.

What Changed With the 2024 DOL Rule?

The Department of Labor's 2024 final rule rescinded the 2018 rule that had made it much easier for loosely connected employer groups to qualify as a single AHP employer. The 2018 rule let associations form around geography alone or around the simple fact of buying insurance together, and it let self-employed individuals with no employees join. Multiple states, led by New York, challenged that rule in federal court, and a federal appeals court struck down its central provisions. The Department of Labor's 2024 rescission, effective June 29, 2024, formally returned the legal standard to the sub-regulatory guidance the agency used for decades before 2018, according to the Department of Labor and reporting from the Center on Health Insurance Reforms at Georgetown University. An association that qualified easily under the 2018 rule may not qualify at all under the current standard.

What Is the Current Test for a Bona Fide Association?

The current Department of Labor standard requires an association to pass three separate tests before it can act as a single employer for health plan purposes. First, the group must be a bona fide organization with a real business or organizational purpose that has nothing to do with selling insurance, such as a genuine trade association or professional group that existed before anyone proposed a health plan. Second, the member employers must share a real commonality of interest, meaning a genuine economic or representational relationship unrelated to the benefits themselves, not just a shared ZIP code or a shared desire for cheaper coverage. Third, the member employers must actually control the plan in both form and substance, meaning real member businesses sit on the board and make real decisions, not an insurance broker or third-party administrator running the show behind the scenes. Failing any one of the three tests means the arrangement is not a valid single-employer AHP under the Department of Labor's guidance.

Why Does It Matter Whether an Association Passes This Test?

It matters because a plan that fails the bona fide association test does not get treated as one large-group plan. Each participating small business is instead treated as its own separate small-group plan under state and federal law, which means each one is individually subject to Affordable Care Act small-group rules including essential health benefits, community rating, and the small-group underwriting rules that the AHP structure was meant to sidestep. An employer that joined an AHP believing it qualified, only to have the arrangement fail an audit or a legal challenge later, can find its coverage retroactively reclassified, which creates real exposure for both the employer and its employees over claims that were paid under the wrong set of rules. This is the central risk with any AHP marketed today: the sales pitch describes the plan design, but the legal qualification is what actually determines whether that design holds up.

What Should a Small Employer Check Before Joining an Association Health Plan?

A small employer should verify all three parts of the Department of Labor's bona fide association test in writing before enrolling, not rely on a broker's assurance that the plan is compliant. Ask how long the sponsoring association existed and what it does besides offer insurance. Ask who sits on the board that controls plan decisions, and confirm those board members are actual owners or executives at member businesses, not employees of an insurance company or third-party administrator. Ask for the plan's ERISA filing history and whether it has faced any state insurance department challenges, since several AHPs formed under the 2018 rule have faced exactly this kind of scrutiny since the rescission. A plan that cannot answer these questions clearly is a plan built on the older, now-invalid standard.

How Do Association Health Plans Compare to Other Small Business Options?

An association health plan is one of several ways a small employer can try to access group-style pricing and coverage, alongside a level-funded plan, a fully insured small-group plan, or an <a href="/blog/how-does-ichra-work">ICHRA arrangement</a> that reimburses employees for individual coverage instead. The table below compares the four on the factors that matter most to a small employer deciding between them.

Option	Underwriting basis	Main advantage	Main risk
Association health plan	Treated as one large group if the association qualifies	Access to large-group rates and rules if the test is met	Legal qualification can fail or be challenged after enrollment
Fully insured small-group plan	Each employer underwritten individually under ACA small-group rules	Simple, fully compliant, predictable premium	No pooling advantage across unrelated employers
Level-funded plan	Employer's own group experience, with stop-loss protection	Potential refund if claims run low, more cost transparency	Employer bears more risk than fully insured coverage
ICHRA	No group underwriting at all; employees buy individual coverage	Fixed, predictable employer cost, employee choice of plan	Employees shop the individual market instead of a group plan

Does Section 125 Still Apply if an Employer Joins an Association Health Plan?

Yes. A Section 125 cafeteria plan works the same way regardless of which underlying health plan an employer offers, including an association health plan, because <a href="/blog/section-125-cafeteria-plan-2026-guide">Section 125</a> governs how the employee's premium contribution is deducted from payroll, not how the underlying insurance is underwritten. An employer that joins a qualifying AHP can still let employees pay their share of the premium with pre-tax payroll deductions, generating the same employer FICA savings covered in our <a href="/blog/maximizing-fica-tax-savings">FICA tax savings breakdown</a>. This is true whether the employer ultimately chooses an AHP, a level-funded plan, or a fully insured plan, which means the AHP qualification question and the Section 125 savings question are two separate decisions an employer can evaluate independently.

Frequently Asked Questions

What is an association health plan?

An association health plan is a group health plan sponsored by a qualifying association of employers, treated under ERISA as one single employer plan instead of many separate small employer plans. If the association qualifies, its combined member businesses can be underwritten and priced as one large group.

Are association health plans still legal in 2026?

Yes, but under a stricter standard than the one that applied from 2018 to 2024. The Department of Labor rescinded the 2018 expansion effective June 29, 2024, returning the qualification test to the sub-regulatory guidance used for decades before that rule, according to the Department of Labor's final rule notice.

What are the three tests for a bona fide association health plan?

The association must be a genuine organization with a business purpose unrelated to selling insurance, the member employers must share a real commonality of interest unrelated to the benefits themselves, and the member employers must actually control the plan in both form and substance. Failing any one of the three tests means the arrangement does not qualify as a single-employer plan.

What happens if an association health plan fails to qualify?

Each participating small business is instead treated as its own separate small-group plan, subject to Affordable Care Act small-group rules the AHP structure was meant to avoid. Coverage that was paid out under the wrong classification can be challenged, creating financial exposure for both the employer and its employees.

Can a self-employed person with no employees join an association health plan?

Under the current post-2024 standard, this is much harder than it was under the 2018 rule, which specifically allowed working owners with no employees to join. The pre-2018 guidance the DOL restored generally expects participating members to be genuine employers with common-law employees, not sole proprietors joining only to access group insurance.

Does an association health plan affect a Section 125 cafeteria plan?

No. A Section 125 plan governs how an employee's premium share is deducted from payroll, not how the underlying health coverage is underwritten. An employer in a qualifying association health plan can still offer pre-tax payroll deductions the same way it would with any other group health plan.

How is an association health plan different from a level-funded plan?

An association health plan pools an employer with other member businesses and is underwritten based on the combined group if the association qualifies. A level-funded plan keeps each employer's own claims experience separate, paired with stop-loss insurance to cap the employer's risk, and does not depend on any association qualification test.

Who enforces the rules on association health plans?

The Department of Labor interprets and enforces the ERISA standard for whether an association qualifies as a single employer. State insurance departments also have authority over plans operating in their state, and several state challenges to AHPs formed under the invalidated 2018 rule have already worked through federal courts.

Wondering whether your association buying group would hold up under the current DOL standard, or whether a level-funded plan or Section 125 setup makes more sense for your business? Summit Health Benefits will walk through your options with you.
