Choosing an FSA, HSA or HRA: Differences and How They Work Together

When choosing an FSA, HSA or HRA, it is easy to get lost in all the rules and regulation. Employers want to enhance their benefits strategy without increasing insurance costs, and tax-advantaged health accounts are often one of the most effective solutions. Health Savings Accounts (HSAs), Flexible Spending Accounts (FSAs), and Health Reimbursement Arrangements (HRAs) all provide ways for employees to pay for eligible medical expenses using tax-free dollars.

While FSAs, HSAs, and HRAs all help employees pay for qualified healthcare expenses, they each have unique rules, tax advantages, and eligibility requirements. Understanding these differences, and when these accounts can be used together, can help employers build a more flexible and cost-effective benefits strategy while giving employees greater control over their healthcare spending.

In many cases, employers also choose to layer more than one of these accounts to maximize value. Understanding the differences, and knowing when these accounts can work together, is key to getting the most out of your benefits program.

Let’s take a closer look at how each of these accounts works and when it may be the right fit for your benefits strategy.

Health Savings Accounts (HSA)

Ownership

HSAs are owned by the employee, not the employer. Employees retain the account if they change jobs, retire, or leave the company. Funds roll over from year to year with no limit, making an HSA a valuable long-term savings vehicle for healthcare expenses.

Flexibility and Growth Potential

Employees may be able to invest HSA balances once minimum thresholds are reached, allowing for long-term growth. Unlike many other benefit accounts, HSAs are not subject to “use it or lose it” rules.

Eligibility

To contribute to an HSA, an employee must be enrolled in a qualifying High Deductible Health Plan (HDHP). Enrollment in a non-HDHP medical plan, including coverage through a spouse or parent, generally makes an individual ineligible to contribute.

Contributions and Taxes (2026 Limits)

• Up to $4,400 for self-only coverage
• Up to $8,750 for family coverage
• Additional $1,000 catch-up contribution for individuals age 55 or older

Employees may contribute through pre-tax payroll deductions or make after-tax contributions and claim the deduction when filing their federal income tax return. Employer contributions are excluded from taxable income and are not subject to payroll taxes.

Flexible Spending Accounts (FSA)

Plan Compatibility

FSAs are an excellent option when offering a traditional group health plan. Unlike HSAs, they do not require enrollment in a High Deductible Health Plan and can be paired with most major medical plans.

Rollover Allowance (2026)

If the employer chooses to allow a rollover feature, the IRS permits up to $680 of unused health FSA funds to carry into the following plan year. Any amount above the allowable rollover is forfeited unless the plan instead uses a grace period.

Employer Advantage

If rollover is permitted, only unused amounts above the rollover limit are forfeited. If a grace period is used instead, forfeitures occur after the grace period expires.

Contributions and Taxes (2026 Limits)

• Maximum employee salary reduction: $3,400

Employer contributions, when offered, are tax deductible and excluded from employee income. Employee salary reductions are generally exempt from FICA and FUTA taxes.

Health Reimbursement Arrangements (HRA)

Plan Design

HRAs offer a high degree of flexibility and can be customized based on employee classes, coverage type, or reimbursement categories. Today, HRAs are used by employers of all sizes to reimburse healthcare expenses and insurance premiums while creating a more predictable benefits budget.

Compatibility with Other Accounts

HRAs may be offered alongside FSAs and, in certain situations, alongside HSAs when structured as either a limited-purpose HRA, which reimburses only eligible dental and vision expenses, or a post-deductible HRA, which reimburses eligible medical expenses only after the IRS minimum annual deductible for an HSA-qualified health plan has been met. Proper plan design is essential to maintain HSA eligibility.

Contributions and Taxes

HRAs are funded solely by the employer. Reimbursements are generally tax-free to employees, while employer contributions are tax deductible and not subject to FICA or FUTA taxes. Unlike HSAs and FSAs, there is no IRS-established annual contribution limit, although the plan must comply with applicable IRS, ERISA, and other regulatory requirements.

Can You Offer More Than One Account Type?

Yes. One of the biggest misconceptions about account-based benefits is that employers must choose a single solution. In reality, many organizations combine different account types to create a more comprehensive and cost-effective benefits strategy.

Each account serves a different purpose. An HSA helps employees save for current and future healthcare expenses, an FSA provides tax-advantaged dollars for eligible out-of-pocket costs, and an HRA allows employers to reimburse eligible expenses or insurance premiums based on their plan design. When used appropriately, these accounts can complement one another rather than compete.

Some common examples include:

• HSA + Limited-Purpose FSA: Allows employees to continue contributing to an HSA while using pre-tax dollars for eligible dental and vision expenses.
• HSA + Post-Deductible HRA – Provides employer-funded reimbursement for eligible medical expenses after the IRS minimum deductible for an HSA-qualified health plan has been met, preserving HSA eligibility while adding financial support for employees.
• Traditional Group Health Plan + FSA: Helps employees pay for deductibles, copays, prescriptions, and other qualified medical expenses with pre-tax dollars.
• HRA + FSA: Employers can use an HRA to reimburse specific healthcare expenses while offering an FSA to provide employees with additional flexibility for out-of-pocket costs.
• Premium-Only HRA + HSA: When an employer offers a premium-only HRA that reimburses individual health insurance premiums but does not reimburse medical expenses, employees enrolled in an HSA-qualified health plan may still be eligible to contribute to an HSA.

Because IRS rules vary depending on how these accounts are structured, it’s important to design them carefully. Working with an experienced benefits administrator helps ensure your benefits strategy maximizes tax advantages while remaining compliant.

Frequently Asked Questions About FSA, HSA, and HRA

What is the difference between an FSA, HSA, and HRA?

An FSA is typically funded through employee salary reductions and is offered alongside a traditional health plan. An HSA is employee-owned and requires enrollment in a qualifying HDHP. An HRA is funded solely by the employer and reimburses eligible healthcare expenses based on the employer’s plan design.

Can you have both an HSA and an HRA?

Yes, but it depends on the type of HRA. While a traditional HRA generally is not compatible with an HSA, a limited-purpose HRA or post-deductible HRA can be paired with an HSA when properly designed to meet IRS requirements.

Can you have both an HSA and an FSA?

Generally, a traditional health FSA makes an employee ineligible for HSA contributions. However, a limited-purpose FSA that reimburses only eligible dental and vision expenses may be paired with an HSA.

Which health account is best for employers?

The best choice depends on your organization’s health plan, workforce demographics, budget, and benefits goals. Many employers find that combining account-based benefits creates greater flexibility while maximizing available tax advantages.
