Permitted classes are defined by employment status, location and a few other categories. Sorting every employee into exactly one class, and writing down the rule, is the first step in any ICHRA design.
Pick a written definition of full-time and part-time and apply it the same way to everyone. Counsel should confirm the definition.
Pay basis is a permitted class. Salaried and hourly employees can receive different allowances if each class is treated consistently.
Titles such as sales, service or office are not permitted classes by themselves. A title only works when it also matches a permitted class.
Seasonal employees, union employees and employees still in a waiting period are permitted classes with their own rules.
Each employee belongs in exactly one class at a time. Overlaps and gaps are where compliance problems start.
Once classes are set, model the monthly allowance for each one before you commit.
The rules give you a short list of permitted classes and one hard requirement: everyone in a class is treated the same. The work is turning your actual workforce into that structure and writing the rule down before the first notice goes out.
Under the individual coverage HRA rules, an employer can define classes of employees by full-time or part-time status, salaried or hourly pay, seasonal status, coverage under a collective bargaining agreement, a waiting period, work location in a particular rating area, and temporary employment through a staffing firm. Some employers also use non-resident aliens with no U.S.-source income as a class. Classes can be combined, so full-time hourly employees in one rating area can be a class of their own. What you cannot do is invent a class, such as sales or service staff, that is not on the list.
Within a class the allowance has to be offered on the same terms to everyone. The one built-in flexibility is that the allowance can rise with an employee age and with the number of family members covered, within the limits the rules allow. Counsel should review the class definitions, and when a group plan is offered to some classes and an ICHRA to others, minimum class size rules can apply to certain classes.
Take a service business with about forty employees. The table shows how its workforce could map to classes. The groups and rules are illustrative, and the real definitions need counsel review.
| Employee group | Pay and hours | Class | Note |
|---|---|---|---|
| Managers and office staff | Salaried, full-time | Full-time salaried | One allowance for the class |
| Technicians | Hourly, full-time | Full-time hourly | Allowance can differ from the salaried class |
| Lot and delivery staff | Hourly, under the part-time threshold | Part-time hourly | Threshold must be written down |
| Summer crew | Hired for the season | Seasonal | Seasonal definition in the plan |
| Anyone in the first 60 days | Any status | Waiting period | Controls until the waiting period ends |
Illustrative only. Job titles such as technician or manager are used here only to describe who sits in each class. They are not classes themselves.
If you want the classes tested against your own census, our fit analysis and the allowance calculator are the next steps, and we can run both for you.
No. The rules list the permitted classes. An employer picks among them and cannot invent new ones.
Within a class the allowance must be the same for everyone, except that it may rise with age or family size within the limits the rules allow.
Yes, when their status actually changes, for example from part-time to full-time. Document the rule and apply it consistently.
No. Employers pick the classes that match their workforce, and some classes depend on facts such as a union agreement.
The employer sets a written definition within what the rules allow. Counsel should review it before the first notice.
Each employee needs one governing class. Write the order of precedence into the plan, and have counsel confirm it, before assigning anyone.
The permitted classes are the same, but the practical choices differ. Our industry pages show how each workforce is usually sorted.
