FSA vs HSA vs HRA: An Employer’s Comparison for 2026

By Tax Benefit Strategies | Published October 30, 2026 | Updated November 2026 | 6 min read

FSAs, HSAs and HRAs all pay for medical costs with tax-free money. For an employer, they are very different tools. They differ in who puts the money in, who keeps it, and what each one costs or saves you.

This guide compares the three from the employer’s side, with the 2026 limits, so you can decide which one fits your workforce.

What Is the Difference Between an FSA, an HSA and an HRA?

An FSA is an employer plan that employees fund from pre-tax pay and mostly spend within the year. An HSA is an account the employee owns, paired with a high-deductible health plan. An HRA is funded only by the employer.

	Health FSA	HSA	HRA
Who funds it	Mostly the employee, by salary reduction	Employee, employer or both	Employer only
2026 limit	$3,400 per employee	$4,400 self-only, $8,750 family, plus $1,000 at age 55+	Set by the employer (QSEHRA and excepted benefit HRAs have caps)
Health plan needed	No specific plan type	HSA-qualified high-deductible health plan	Depends on the HRA type
Unused money	Forfeited, except a $680 carryover or a 2.5-month grace period	Rolls over every year	Employer decides
When an employee leaves	Stays with the plan	Goes with the employee	Stays with the employer
Employer payroll tax effect	Saves 7.65% FICA on what employees elect	Saves 7.65% FICA on contributions made through a cafeteria plan	No payroll tax on HRA dollars, but every dollar is employer money

How Does a Health FSA Work for Employers?

A health FSA lets employees set aside up to $3,400 in 2026 from pay before income tax and FICA tax. The employer saves 7.65% FICA on each dollar. The full annual election is available on day one, so the employer carries some risk.

Uniform coverage. If an employee spends the full year’s election in March and then quits, the plan absorbs the difference.
Use it or lose it. Unused money is forfeited to the plan. The plan can allow a carryover of up to $680 into 2027, or a grace period of 2.5 months, but not both.
Limited-purpose FSA. A general-purpose health FSA stops HSA contributions. If you offer an HSA plan, offer a limited-purpose FSA for dental and vision costs instead.

A dependent care FSA is a separate account with its own limit: $7,500 per household from 2026. See our guide to the dependent care FSA limit.

How Does an HSA Work for Employers?

An HSA is a personal account the employee owns. To contribute, the employee must be on an HSA-qualified high-deductible health plan (HDHP). HSA contributions made through a cafeteria plan are free of income tax and FICA tax.

2026 HDHP minimum deductible: $1,700 self-only, $3,400 family. The out-of-pocket maximum is $8,500 self-only and $17,000 family.
2027 HSA limits: $4,500 self-only and $9,000 family. The HDHP minimum deductible rises to $1,750 and $3,500.
The employee keeps the money. Unused HSA money rolls over and goes with the employee if they leave.

The 2025 tax law made HSAs available to more employees from 2026:

Bronze and catastrophic plans available as individual coverage through an Exchange are treated as HSA-qualified.
Direct primary care arrangements with fees of up to $150 a month ($300 for more than one person) no longer block HSA contributions.
Telehealth before the deductible is now permanently allowed with an HSA plan.

For how an HSA compares with a Section 125 cafeteria plan itself, see Section 125 vs. HSA.

How Does an HRA Work for Employers?

An HRA (health reimbursement arrangement) is funded only by the employer. Employees cannot put their own pay into it. The employer decides how much to offer and which expenses qualify, and usually keeps money employees do not use.

There are four main types:

Integrated HRA. Works only with your group health plan, often to help pay the deductible. No IRS dollar limit.
ICHRA. Reimburses individual health insurance premiums for employers of any size. CMS renamed it a CHOICE Arrangement in September 2026; the rules did not change.
QSEHRA. Only for employers with fewer than 50 full-time employees and no group plan. The 2026 limit is $6,450 self-only and $13,100 family.
Excepted benefit HRA. Offered next to a group plan, up to $2,200 for plan years starting in 2026 and $2,250 in 2027.

Which Account Should an Employer Offer?

Choose by your health plan and your budget. Offer an HSA if your plan is an HDHP. Offer a health FSA if it is not. Use an HRA when you want to put in employer money and control how it is spent.

You have a traditional group plan: a health FSA, plus an integrated HRA if you want to help with deductibles.
You have an HDHP: an HSA, plus a limited-purpose FSA.
You have no group plan: an ICHRA, or a QSEHRA if you have fewer than 50 employees. See how QSEHRA and ICHRA compare.

None of the three changes payroll tax for employees who do not take part. In a workforce of hourly employees, that is often most of the staff.

How Do These Accounts Fit With a Section 125 Savings Plan?

Health FSA and HSA payroll contributions both run through a Section 125 cafeteria plan, but they save payroll tax only for employees who elect them. A full Section 125 savings plan includes every employee, so the savings reach the whole workforce.

Employer savings: most employers save $650–$850 per employee per year.
Employee pay: take-home pay typically rises about 4–6%.
New benefits: unlimited virtual care with no copay, $0-copay generic prescriptions and hospital indemnity cash benefits.
Fit: it works alongside your existing health insurance and an existing dependent care FSA or health FSA, and alongside an ICHRA or HSA in most cases.

There is no setup fee and no minimum contract. The per-employee monthly fee is paid from the tax savings. Our program requires at least 50 employees. Read the Section 125 plan guide for how it works, or estimate your savings.

Frequently Asked Questions

Can an employee have an FSA and an HSA at the same time?

Not a general-purpose health FSA. It stops HSA contributions. An employee can pair an HSA with a limited-purpose FSA that covers only dental and vision costs, or with a dependent care FSA.

Can employees contribute to an HRA?

No. Only the employer funds an HRA. Employees cannot put their own pay into it. That is the main difference between an HRA and an FSA.

Which account saves the employer the most payroll tax?

FSA and HSA payroll contributions save the employer 7.65% FICA on each dollar employees elect. The total depends on how many employees take part. HRA dollars are employer money, so they add cost.

What happens to unused money when an employee leaves?

HSA money goes with the employee. Unused health FSA money generally stays with the plan, unless COBRA applies. Unused HRA money stays with the employer.

What are the 2027 limits?

The 2027 HSA limits are $4,500 self-only and $9,000 family. The dependent care FSA stays $7,500. The IRS has not yet announced the 2027 health FSA limit.
