Tips for Controlling Benefit Costs Using Tiered Employee Classes

Tired of unpredictable health insurance renewals and premiums that seem to only go up? You’re not alone. For many businesses, healthcare is a volatile expense that’s difficult to plan for. But what if you could turn that unpredictable cost into a fixed, manageable line item? With an Individual Coverage HRA (ICHRA), you can.

An ICHRA allows you to give employees tax free funds to buy their own health insurance. The key to cost control lies in how you structure those funds. By creating different benefit tiers for groups like full time versus part time staff or employees in different geographic locations, you can turn a volatile expense into a predictable one. This guide provides actionable tips for controlling benefit costs using tiered employee classes, helping you create a fair, flexible, and budget friendly health benefits program.

The Foundation: Predictable Budgeting with a Fixed Allowance

Before diving into classes, it’s important to understand the fundamental shift an ICHRA represents. Traditional group plans are a “defined benefit”, where you pay a percentage of a premium that can skyrocket at renewal. An ICHRA is a “defined contribution” model. You decide exactly how much to contribute per employee, and that number doesn’t change unless you want it to.

This transforms healthcare spending from a wild card into a predictable expense. In fact, while over two thirds of CFOs find traditional health benefits to be a significant, unpredictable concern, an ICHRA locks in your costs. You set the budget, and that’s what you spend. This predictability is the first step in getting a handle on your expenses.

What Are Employee Classes and How Do They Work?

Employee class design is the core strategy for cost control with an ICHRA. It involves dividing your workforce into logical, job based groups and offering different allowance amounts or benefits to each one. For step‑by‑step ideas, see our guide to designing eligibility criteria for benefit classes. This allows you to tailor your spending, allocating more resources where they have the most impact on recruiting and retention.

The IRS allows you to create classes based on 11 distinct categories, including:

• Full time vs. Part time employees
• Salaried vs. Hourly employees
• Employees in different geographic locations (state or rating area)
• Seasonal or temporary employees
• Union vs. Non union employees
• And combinations of the above (e.g., full time salaried employees in California)

The golden rule is that all employees within the same class must be treated equally. With that in mind, let’s explore some key tips for controlling benefit costs using tiered employee classes.

Core Strategies for Tiering Employee Benefits

Differentiate by Work Status: Full Time vs. Part Time

One of the most common and effective tips for controlling benefit costs using tiered employee classes is to differentiate between your full time and part time staff. Historically, benefits for part timers have been rare. Only 19% of part time workers are covered by their own employer’s health plan, compared to 59% of full-time civilian workers participated in employer-sponsored medical care plans in March 2024.

With an ICHRA, you have options:

• Offer a Higher Allowance to Full Timers: You can provide a generous allowance to your full time staff (e.g., 30+ hours per week) and a smaller, prorated allowance to part timers.
• Cover Full Timers Only: It is perfectly legal to offer an ICHRA to your full time employee class and offer nothing to the part time class. This lets you focus your budget on the employees you most need to retain.

This strategy aligns your benefit spend with an employee’s contribution to the company and is a powerful lever for managing your budget.

Align with Pay Structure: Salaried vs. Hourly

Another powerful method is to create separate classes for salaried (exempt) and hourly (non exempt) employees. Their roles, pay structures, and benefit expectations are often different, and your ICHRA can reflect that.

For instance, you could offer a more competitive allowance to salaried managers and professionals to attract top talent. Conversely, you might offer a higher percentage of premium coverage to your full time hourly workers to ensure their benefit offer meets ACA affordability rules, which are based on income. Separating these groups gives you the flexibility to meet the distinct needs of each segment of your workforce.

Adjust for Local Costs: Geographic Location

Health insurance premiums vary wildly from one place to another. A plan in New Hampshire might cost around $401 per month, while a similar plan in Vermont could be nearly $1,300. Offering a single, flat allowance to a distributed team is both inefficient and unfair.

Using geographic classes is one of the smartest tips for controlling benefit costs using tiered employee classes. You can create classes by state or even by insurance rating area, offering higher allowances to employees in high cost markets and lower allowances in more affordable ones. This ensures every employee receives a benefit with similar purchasing power, and it prevents you from overspending in low cost regions. For companies embracing remote work, this is an essential tool. For multi‑state teams, review our ICHRA compliance by state guide for class rules and notices.

Factor in Demographics: Age and Family Size

Group health plans naturally spread the risk and cost across different demographics. An ICHRA can mimic this fairness through age and dependent based allowances.

• Age Based Tiers (The 3:1 Rule): Insurance premiums are higher for older individuals. The ACA allows insurers to charge an older adult up to three times more than a younger one. Your ICHRA can mirror this by offering a higher allowance to older employees, as long as the allowance for the oldest employee in a class is no more than three times the allowance for the youngest. For example, you could give a 25 year old $200 per month and a 60 year old up to $600.
• Dependent Tiers: Supporting a family costs more. The average annual premium for family coverage ($23,968) is nearly three times that of single coverage ($8,435). An ICHRA allows you to offer higher allowances to employees covering a spouse or children. You might set tiers like:
  • Employee Only: $400/month
  • Employee + Spouse: $750/month
  • Employee + Family: $1,000/month

These adjustments ensure your benefit is meaningful for everyone, from single young professionals to employees with families.

Manage Temporary Staff: Seasonal Workers

Do you hire extra help during a busy season? The IRS allows a separate class for seasonal employees. Because the ACA has special rules for seasonal workers (often not requiring coverage for short term work), you have complete flexibility. You can choose to:

• Exclude the seasonal class from the ICHRA entirely.
• Offer a smaller, prorated allowance just for the months they work.

This is another of the powerful tips for controlling benefit costs using tiered employee classes, as it prevents you from paying for year round benefits for short term staff.

Advanced Strategies and Compliance Guardrails

Once you have your classes designed, a few more strategies can optimize your plan.

The Premium Only Policy: A Simple Way to Limit Spend

An ICHRA can be set up to reimburse insurance premiums plus other qualified medical expenses (like copays and prescriptions). However, for maximum cost control, you can implement a “premium only” policy. This means the HRA funds can only be used for insurance premiums. If you reimburse beyond premiums, make sure you’re clear on reimbursement types and tax rules.

This approach simplifies administration and makes your costs even more predictable. Any unused funds stay with the company. Data shows this is a popular choice, with about 42% of employers choosing a premium only HRA design.

Staying Compliant: ACA Affordability Safe Harbors

If you are an Applicable Large Employer (ALE) with 50 or more full time equivalent employees, you must offer coverage that is affordable under the ACA. To make this easier, the IRS provides “safe harbors”. The Federal Poverty Line (FPL) safe harbor is a common choice. See our 2026 ICHRA affordability guide to stay compliant.

For the 2026 plan year, this means an employee’s monthly contribution for the lowest cost self only plan can’t exceed $129.90. You can use this number to budget your ICHRA allowance. If the cheapest plan in an employee’s area is $550, you would need to offer an allowance of at least $420.10 to meet the safe harbor ($550 minus $129.90). Using a safe harbor is a key budgeting tool to guarantee compliance and avoid penalties.

Mixing and Matching: Combining ICHRA with a Group Plan

What if you have a group plan that works well for some employees but not others? You can offer a traditional group plan to one class (say, salaried headquarters staff) and an ICHRA to another (like your remote hourly workers).

However, if you do this, a minimum class size rule kicks in for certain classes to prevent discrimination. For example, for a company with fewer than 100 employees, an ICHRA class must have at least 10 people. This rule only applies when you are offering both plan types; if everyone is on an ICHRA, there are no class size minimums. If you have multiple entities under common ownership, review how controlled group rules affect ALE testing and ICHRA offers.

Frequently Asked Questions

What are the main benefits of using tiered employee classes for an ICHRA?

The primary benefits are cost control, flexibility, and fairness. You can direct your budget to the employees you most need to attract and retain, adjust for factors like geographic cost differences, and create a benefit that is equitable for employees of all ages and family situations. This approach provides more granular control than a one size fits all group plan.

Can I offer a different ICHRA allowance to just one specific person?

No. You cannot create a “class of one”. Allowances and benefits must be offered uniformly to all employees who fall into a bona fide, job based class (like “part time” or “salaried”). This is a key nondiscrimination rule.

Is it complicated to set up and manage these different employee classes?

While the rules can seem complex, using a dedicated ICHRA administration platform makes it simple. Software like SimplyHRA guides you through creating compliant classes, calculating affordability, and managing reimbursements, automating most of the work. For a head start, use our ICHRA onboarding checklist for new employer customers.

What happens if an employee moves from one class to another, like from part time to full time?

When an employee’s job status changes, they would move into the new class and become eligible for the ICHRA benefits associated with that class. For example, a part time employee moving to a full time role would gain access to the full time allowance, typically starting the first of the month following the change.

Do I have to use employee classes with an ICHRA?

Not at all. Many small businesses keep it simple by using a single class for all employees and offering everyone the same allowance. In a 2021 analysis, 72% of employers used only one class. Using multiple classes is a powerful option, but it is not a requirement. This is just one of many tips for controlling benefit costs using tiered employee classes.

How do geographic allowances help with cost control?

Geographic allowances prevent overspending. By giving employees in low cost states an allowance that fits their market, you avoid providing an unnecessarily large contribution. At the same time, you can offer a higher allowance to employees in expensive states, ensuring their benefit is still competitive and useful without blowing your overall budget.
