Employee Class and Allowance Rules

Learn how large employers can structure ICHRA employee classes and allowances while maintaining consistent plan terms and addressing ACA affordability requirements.

Sep 18, 2026

Large employers may use permitted employee classes to structure ICHRA eligibility and allowance amounts across different workforce groups. Each class must be based on distinctions allowed under applicable ICHRA rules and should be defined clearly in the governing plan documents.

Employees within the same class generally must be offered the ICHRA on the same terms. Allowance amounts may differ between permitted classes and may vary within a class based on age or family size when the applicable requirements are satisfied and the methodology is applied consistently.

When an employer offers an ICHRA to one class and a traditional group health plan to another, certain class structures may be subject to minimum-class-size requirements. Employers should review class definitions and workforce counts before finalizing the plan design.

For Applicable Large Employers, compliance with ICHRA class rules does not by itself establish affordability under the ACA employer shared responsibility provisions. Allowance decisions should also be evaluated using the applicable affordability methodology for the relevant plan year and employee population.

Class definitions, allowance methodology, affordability analysis, and subsequent changes should be documented and coordinated with employee notices and ACA reporting.

Employers remain responsible for selecting permitted classes, establishing allowance amounts, evaluating affordability, and applying plan terms consistently.
