The landscape of corporate health benefits in the United States is undergoing a fundamental transformation as employers move away from one-size-fits-all group insurance plans toward more flexible, "defined contribution" models. At the forefront of this shift is the Individual Coverage Health Reimbursement Arrangement (ICHRA), a benefit structure that has gained significant traction since its inception in early 2020. For organizations managing a diversified workforce—particularly those with remote employees or operations spanning multiple state lines—the ICHRA offers a level of adaptability that traditional group plans often struggle to match. However, as the adoption of these arrangements grows, so does the complexity of the regulatory framework surrounding them, specifically regarding minimum class size requirements and geographic eligibility.
The Genesis and Evolution of the ICHRA Framework
To understand the current state of ICHRAs, one must look at the regulatory timeline that enabled their creation. In June 2019, the Department of the Treasury, the Department of Labor, and the Department of Health and Human Services (HHS) issued the "ICHRA Final Rules." These rules were designed to expand the flexibility of Health Reimbursement Arrangements (HRAs) by allowing them to be integrated with individual market insurance. This was a landmark shift from the post-Affordable Care Act (ACA) environment, where stand-alone HRAs were largely restricted.
The implementation of ICHRAs officially began on January 1, 2020. Since then, the model has seen a steady increase in utilization. According to data from the HRA Council, ICHRA adoption grew by triple digits in the years following its introduction, as businesses sought to mitigate the rising costs of traditional group premiums, which have historically outpaced inflation. The model allows employers to set a fixed monthly allowance for employees, who then purchase their own health insurance on the individual market. This effectively shifts the risk of premium volatility from the employer to the broader market while giving employees the freedom to choose plans that suit their specific medical needs and provider preferences.
The Mechanics of the Individual Coverage HRA
An ICHRA is an employer-funded, tax-advantaged health benefit. Unlike a traditional group health plan, where the employer selects a specific carrier and plan design for the entire staff, the ICHRA functions as a reimbursement vehicle. The employer grants employees a monthly allowance, and the employees use those funds to pay for individual health insurance premiums and other out-of-pocket medical expenses.
The process is governed by a strict set of operational steps:
- Allowance Setting: The employer defines monthly reimbursement limits. These can be varied based on age or family size, ensuring that older employees or those with dependents receive equitable support relative to the cost of their premiums.
- Coverage Procurement: Employees purchase a qualifying individual health insurance plan, which may include plans found on the ACA exchanges (Marketplace) or private off-exchange plans.
- Verification of Coverage: Employees must provide proof of enrollment in qualifying coverage to remain eligible for reimbursements.
- Expense Reimbursement: Employees submit claims for premiums or eligible medical expenses—of which there are over 200 categories defined by the IRS, including prescription drugs, dental care, and vision services—and the employer reimburses them tax-free.
Deciphering the Minimum Class Size Rules
One of the most frequent points of confusion for human resources departments and benefit administrators involves the "minimum class size" rules. These regulations were established by federal agencies to prevent "cherry-picking"—a practice where an employer might move high-risk or sickly employees into the individual market (via an ICHRA) while keeping healthy employees on a traditional group plan.
It is critical to note that minimum class size rules do not apply to all organizations. They are only triggered if an employer chooses to offer a traditional group health insurance plan to one group of employees and an ICHRA to another group of employees. If an organization offers only an ICHRA to its entire staff, these size restrictions are waived.
When the rules do apply, the minimum number of employees required in a class depends on the total size of the organization:
- Small Employers: For organizations with fewer than 100 employees, the minimum class size is 10 employees.
- Medium Employers: For organizations with 100 to 200 employees, the minimum class size is 10% of the total employee count.
- Large Employers: For organizations with more than 200 employees, the minimum class size is 20 employees.
These thresholds are calculated at the beginning of the plan year based on the number of employees offered the benefit.
Strategic Application for Multi-State and Remote Teams
The question of whether an employer can offer an ICHRA exclusively to out-of-state employees is a common one in the era of the "anywhere workforce." The short answer is yes, provided the classes are structured in accordance with federal guidelines.
Employers are permitted to categorize employees into distinct "classes." Common classes include full-time versus part-time status, salaried versus hourly, seasonal workers, and geographic location. The geographic class is particularly powerful for multi-state employers. Geographic classes can be defined by state lines or by "rating areas" (the geographic regions used by insurance companies to set premiums, often defined by counties or metropolitan areas).
Crucially, state-based classes are exempt from the minimum class size rules. This means an employer in Oregon with 50 employees can offer a traditional group plan to their 48 local employees and an ICHRA to their two remote employees in Michigan and Florida without violating federal size thresholds. However, if the employer attempts to sub-divide those classes further—for example, by offering an ICHRA only to employees in a specific county or rating area within a state—the minimum class size rules are triggered.
Data Trends and Market Reactions
Industry analysts suggest that the ICHRA is solving a significant "portability" problem in the American labor market. Traditional group plans often have "networks" that are geographically restricted. A remote worker in Texas may find that their company’s New York-based group plan offers limited "in-network" options, leading to higher out-of-pocket costs. By utilizing an ICHRA, that Texas-based employee can purchase a plan from a local provider like Blue Cross Blue Shield of Texas, ensuring full access to local doctors and hospitals.
Recent surveys of CFOs indicate that cost predictability is the primary driver for ICHRA adoption. Traditional group premiums have seen annual increases ranging from 5% to 15% in various sectors. In contrast, the ICHRA allows a company to set a budget (e.g., $500 per employee per month) and maintain that budget regardless of how the individual market fluctuates. If premiums rise, the employee chooses a different plan or pays the difference, much like a 401(k) retirement plan shifts investment choice to the worker.
Implications for Compliance and Administration
While the ICHRA offers flexibility, the administrative burden can be higher than a traditional plan due to the need for constant "substantiation"—the process of verifying that employees are actually spending their allowances on qualifying insurance and medical costs. This has led to the rise of specialized ICHRA administration platforms.
Platforms like PeopleKeep and Remodel Health have automated the verification process, ensuring that reimbursements remain tax-compliant under IRS Section 105. These platforms also handle the "Notice Requirement," a federal mandate requiring employers to provide a written notice to employees at least 90 days before the start of the plan year explaining how the ICHRA works and how it affects their eligibility for premium tax credits.
Broader Economic and Policy Impact
From a policy perspective, the ICHRA is seen as a tool to stabilize the ACA individual marketplaces. By moving employer-sponsored individuals into the exchange, the risk pool becomes larger and more diverse. Health policy experts argue that as more healthy, employed individuals enter the individual market via ICHRAs, it may lead to lower overall premiums for everyone in the exchange by balancing out the high-utilization users.
Furthermore, the ICHRA addresses the "job lock" phenomenon, where employees stay in roles they dislike simply to maintain health coverage. Because an ICHRA is based on an individual plan, the coverage is truly portable. If an employee leaves their company, they keep their insurance plan; they simply lose the employer’s reimbursement and must take over the full premium payments themselves.
Conclusion: A Scaling Strategy for Modern Organizations
The Individual Coverage HRA represents a pivot toward employee autonomy and employer fiscal control. By understanding the nuances of class size rules—particularly the exemptions for state-based geographic classes—businesses can tailor their benefits packages to meet the needs of a distributed workforce.
As the workforce continues to decentralize, the ability to offer localized, high-quality health benefits without the administrative nightmare of managing multiple state-specific group plans is a competitive advantage. For the employer with one remote worker in a distant state or a thousand employees spread across the country, the ICHRA provides a compliant, scalable, and predictable pathway to providing essential health benefits in the 21st-century economy. Through thoughtful class design and the utilization of specialized administration tools, organizations can bypass the restrictions of traditional insurance and foster a more resilient and satisfied workforce.
