How to Calculate Employee Classes by Role: 2026 ICHRA Guide

The world of health benefits is changing fast. A flexible alternative to traditional group plans, the Individual Coverage HRA (ICHRA), is seeing explosive growth. In fact, the number of people using ICHRAs is 2.8 times higher than it was just one year ago. Why the sudden popularity? It comes down to one powerful feature: employee classes.
Unlike the one size fits all approach of a single group plan, ICHRAs let you segment your workforce into different groups and offer customized health allowances to each one. The process for how to calculate employee classes by role involves analyzing your team against 11 IRS-approved job categories (like full-time vs. part-time), formally grouping them into these classes, and then setting a specific reimbursement allowance for each one. This guide will walk you through these steps, so you can design a smarter, more affordable, and compliant health benefits strategy for your unique team.
What Are ICHRA Employee Classes?
ICHRA employee classes are the 11 distinct, IRS approved categories you can use to group employees for health benefits. Think of them as predefined buckets based on legitimate job criteria. You can’t just make up your own, but the approved list gives you incredible flexibility.
The whole point is to move beyond offering the same benefit to everyone. Instead, you can create a tailored approach. For example, you can offer a higher reimbursement amount to your full time staff and a lower one to part timers. This is the foundation of how to calculate employee classes by role, using these official categories as a proxy for the different roles within your company.
The 11 official ICHRA employee classes are:
- Full time employees
- Part time employees
- Salaried employees
- Hourly (non salaried) employees
- Seasonal employees
- Employees covered by a collective bargaining agreement (union)
- Employees in a benefits waiting period (new hires)
- Employees working abroad
- Employees in different geographic locations (by state or rating area)
- Temporary employees from a staffing firm
- Any combination of the above
How to Calculate Employee Classes by Role: A Step by Step Guide
Ready to design your plan? Figuring out how to calculate employee classes by role is a strategic process. Here’s how you can break it down.
Step 1: Analyze Your Workforce
Before you can create classes, you need a clear picture of your team. Look at your employee census and group people by objective, job based factors:
- Employment Status: Who is full time versus part time?
- Pay Type: Who is salaried versus paid hourly?
- Location: Are employees all in one office, or are they spread across different states or cities?
- Special Categories: Do you have union members, seasonal workers, or temporary staff from an agency?
This analysis gives you the raw data you need to build a logical class structure that reflects how your business actually operates.
Step 2: Define Your Employee Classes
Using the data from your analysis, you can now officially define your classes using the IRS approved categories. You have complete control over which classes you use. You might only need one or two, or you might need several for a more complex workforce.
Core Employment Classes
These are the most common classes employers use to differentiate benefits.
- Full Time vs. Part Time Employees: This is perhaps the most popular way to segment a team. You can offer a richer benefit to your core full time staff and a different, perhaps smaller, allowance to part time employees who may not have been eligible for benefits at all under a traditional plan. You get to define what “full time” means (for example, 30 or more hours per week), but you must apply it consistently.
- Salaried vs. Hourly Employees: This class is perfect for companies with distinct office and field or production teams. For example, a manufacturing company can create a salaried class for its management and administrative staff and an hourly class for its production floor workers. This strategy helps align benefits with different compensation structures and is a key component of how to calculate employee classes by role.
Specialized Workforce Classes
These classes address unique employment situations.
- Collective Bargaining Agreement (Union) Class: If you have unionized employees, their benefits are typically handled through a collective bargaining agreement (CBA). The ICHRA rules let you place all employees covered by a CBA into their own separate class. This usually means you can exclude them from the ICHRA and continue with their negotiated union health plan.
- Seasonal Worker Class: Businesses in retail, tourism, or agriculture often hire seasonal help. You can put all your seasonal workers into a dedicated class. This gives you the option to offer them a smaller ICHRA allowance for the months they work or to exclude them from health benefits entirely, all while keeping your year round staff on a different plan.
- Temporary Worker Class (Staffing Firm): This class is for workers who are technically employed by a staffing agency but work for your company. It allows a staffing firm to offer an ICHRA to its pool of temporary workers. If you are the company using these workers, you typically would not include them in your plan, as they belong to the staffing agency’s class.
- Waiting Period (New Hire) Class: Most companies have a waiting period (up to 90 days) before new hires are eligible for benefits. You can place all employees currently in this waiting period into a special new hire class. This is a powerful strategy for transitioning away from a group plan. You can keep existing staff on the old plan while offering an ICHRA to all new employees, phasing in the new benefit over time. For a smooth rollout, follow our ICHRA onboarding checklist for new employer customers.
Location Based Classes
- Geographic Location Class: For companies with employees in multiple locations, this class is a game changer. You can group employees by their state or insurance rating area (like a specific county or metro area). This allows you to offer a higher allowance to employees in high cost areas (like New York City) and a different amount to those in lower cost areas, ensuring the benefit is meaningful everywhere. The right approach to how to calculate employee classes by role for a distributed team almost always involves geographic classes.
- Foreign Employee Class: This class is for non resident alien employees who work outside the U.S. and have no U.S. based income. Because they typically can’t enroll in U.S. health insurance, you can place them in this class to formally exclude them from your company’s ICHRA plan.
Advanced Strategy: Using Combination Classes
The rules also allow you to combine two or more of the standard classes to create a hyper specific group. For example, you could create a class for “Salaried employees in California” or “Part time seasonal employees.” This gives you almost limitless customization to fine tune your benefits strategy.
Step 3: Set Eligibility and Allowances by Class
Once you have defined your classes, you decide which ones are eligible for the ICHRA and set a monthly reimbursement allowance for each. This is where your strategy comes to life.
- Eligibility: You don’t have to offer the ICHRA to every class. You might offer an ICHRA to part time employees while keeping full time staff on a traditional group plan.
- Allowances: You can set different monthly allowance amounts for each eligible class. For example:
- Full Time Employees: $500 per month
- Part Time Employees: $250 per month
- Salaried Employees in California: $650 per month
This is how you control costs while directing your benefits budget where it will have the most impact. For larger employers (50+ employees), also known as Applicable Large Employers (ALEs), you must also ensure the allowance you offer to full time employees is considered “affordable” under ACA rules to avoid penalties.
The Key Rules for ICHRA Employee Classes
Flexibility comes with a few important rules to ensure fairness and prevent discrimination. Understanding how to calculate employee classes by role also means understanding these compliance guardrails.
The Uniform Benefit Rule: Treating Everyone in a Class Equally
Within any single class, all employees must be offered the ICHRA on the same terms and conditions. If the “Part Time” class gets a $300 monthly allowance, every employee in that class must be offered that same $300 base allowance. You can’t play favorites.
The only permitted variations within a class are for age and family size. You can offer more to older employees (up to a maximum of 3 times the amount offered to the youngest employees) and more to those with dependents, as long as you use a consistent, uniform formula.
The “No Choice” Rule: One Benefit Type Per Class
You cannot offer employees in the same class a choice between a traditional group health plan and an ICHRA. If you’re weighing options, see our guide on ICHRA vs. group plans: key differences for employers. Each class gets one type of offer. For example, the entire “Salaried” class must be offered the ICHRA, or the entire class must be offered the group plan. They can’t pick and choose individually. This rule prevents risk pooling issues and keeps the system stable.
Minimum Class Size Requirements (When Mixing with a Group Plan)
This rule only applies if you offer a group health plan to one class and an ICHRA to another. To prevent companies from carving out small, high risk groups, certain ICHRA classes must meet a minimum size:
- For employers with fewer than 100 employees: The class must have at least 10 employees.
- For employers with 100 to 200 employees: The class must have at least 10% of the total workforce.
- For employers with over 200 employees: The class must have at least 20 employees.
Important: This rule only applies to classes based on full time, part time, salaried, hourly, or geographic rating area (not state level). Classes for new hires, seasonal workers, or union members are exempt, making them great strategic options for phasing in an ICHRA. And if you offer an ICHRA to all your employees (with no group plan), this rule does not apply at all.
Legitimate Job Based Criteria: The Only Factors You Can Use
You must build your classes using only the 11 approved criteria. You cannot create a class for “managers,” “executives,” or “top performers,” as those are not on the list. The system is designed to be based on objective employment status, not titles or performance, to ensure fairness.

Frequently Asked Questions About How to Calculate Employee Classes by Role
1. Can I create an ICHRA class for executives or managers?
No, you cannot create classes based on job titles like “executive” or “manager.” You must use one of the 11 legitimate job based criteria. However, you can often achieve a similar result by using the “salaried” employee class, as most of your executive team is likely salaried.
2. What happens if an employee changes classes, like moving from part time to full time?
When an employee’s job status changes, you would simply move them to the new class in your administration platform. Their ICHRA allowance would then adjust to the amount designated for their new class, effective on a consistent, predefined date (like the first of the following month).
3. Do I have to offer the ICHRA to every employee class?
No, you are not required to offer an ICHRA to every class. You have the flexibility to offer an ICHRA to certain classes (like part time staff) while excluding others or keeping them on a different benefit like a traditional group plan.
4. How many ICHRA classes can my company have?
There is no legal limit to the number of classes you can have. You can create as many distinct classes as you need to fit your workforce structure, as long as each one is based on the 11 legitimate criteria or a combination of them.
5. How do I determine an “affordable” ICHRA allowance for a class?
For Applicable Large Employers (ALEs), an ICHRA offer is considered affordable if the amount an employee must pay for the lowest cost silver plan in their area (after your allowance) is less than a certain percentage of their household income (around 8.39% for 2024). Platforms like SimplyHRA provide tools and calculators to help you determine safe harbor allowance amounts to meet this requirement.
A Smarter Way to Offer Health Benefits
Mastering how to calculate employee classes by role unlocks the full potential of an ICHRA. It allows you to break free from rigid, expensive group plans and offer a benefit that is truly tailored to your team and your budget. By strategically defining classes and allowances, you can control costs, improve employee satisfaction, and offer competitive health coverage that makes sense for everyone.
