Same terms within a class
The ICHRA generally must be offered on the same terms to participants in a class, subject to permitted variations and specified exceptions. Age and family-size adjustments require consistent rules. A job title such as “executive” or “field supervisor” is not, by itself, a new permitted class.

Schedule an ICHRA Consultation ↗When minimum class sizes matter
Minimum-size rules are conditional. They can apply when an employer offers a traditional group plan to one class and ICHRA to another class based on specified categories, such as full-time, part-time, salaried, non-salaried, or certain geographic distinctions and combinations. They are not a universal requirement that every ICHRA have ten participants.
| Employer size under the regulation | Minimum when the rule applies |
|---|---|
| Fewer than 100 employees | 10 employees |
| 100–200 employees | 10% of employees, rounded down to a whole number |
| More than 200 employees | 20 employees |
Count offers, not just enrollments
The relevant minimum relates to employees offered the ICHRA in the applicable class, using the regulation’s employer-size and timing rules. Geographic exceptions, combinations, and the special new-hire rule need specific review. An enrollment forecast is not a substitute for the class-size test.
Illustrative design question
A contractor wants different benefits for hourly field employees and salaried office employees. Salaried versus non-salaried status can be relevant, but the employer still needs to evaluate the actual classifications, same-terms rules, group-plan interaction, and applicable minimums. Simply naming the groups “field” and “office” does not complete the analysis.
