HRA vs HSA vs FSA (and Where ICHRA Fits): An Employer's Guide
By the PlanVantage engine teamPublished September 3, 20267 min read
Health accounts are where benefits strategy gets personal. The plan design decides what care costs; the account decides who pays it, with whose dollars, and on what tax terms. Yet the three main accounts (the HSA, the HRA, and the FSA) are routinely confused with one another, and the newest arrival, the ICHRA, gets described as a fourth account when it is really a different way to buy coverage. This guide sorts them out: who owns each, who funds each, what the 2026 limits are, and when each one is the right tool.
The Comparison at a Glance
| Feature | HSA | HRA | FSA |
|---|---|---|---|
| Who owns it | The employee | The employer | The employer |
| Who funds it | Employee and employer | Employer only | Mostly employee, pre-tax |
| Annual limit | $4,400 self-only / $8,750 family in 2026; $4,500 / $9,000 in 2027 | No limit (integrated HRAs) | $3,400 in 2026; the 2027 figure arrives from the IRS in the fall |
| Portability | Fully portable, invests, rolls forever | Stays with the employer | Stays with the employer |
| Unused funds | Always the employee's | Roll over at employer's discretion | Forfeited, small carryover allowed |
| Required pairing | Qualified HDHP | Group plan (or individual coverage, for ICHRA) | Employer group medical plan (must be offered alongside one) |
| Administration | Custodial bank account; light employer admin | Employer plan document; claims adjudicated by a TPA | Cafeteria plan with nondiscrimination testing; TPA-run |
Who Owns and Funds Each Account
Ownership is the fastest way to keep the three straight, because everything else follows from it.
A health savings account (HSA) is the employee's asset, full stop. Both the employee and the employer can contribute, the balance can be invested, and it follows the employee through job changes and into retirement. The catch is eligibility: the employee must be enrolled in a qualified high-deductible health plan, with no disqualifying other coverage and no Medicare enrollment. Even a spouse's general-purpose FSA can disqualify an otherwise eligible employee, a trap that surfaces every open enrollment. The same disqualification applies to HRAs, and it is the most common way employers break HSA eligibility by accident. A general-purpose HRA is disqualifying coverage. Pairing an HRA with an HSA requires a limited-purpose HRA covering dental and vision only, a post-deductible HRA that pays nothing until the statutory minimum deductible is met, a retiree-only HRA, or a suspended HRA.
A health reimbursement arrangement (HRA) is the employer's promise, not a funded account. Only the employer can put money in, and in most designs no money moves at all until an employee submits an eligible claim. The employer defines what counts: some HRAs reimburse anything under IRS Section 213(d), others only deductible expenses on the medical plan. That design freedom is the HRA's core advantage.
A flexible spending account (FSA) is an employee salary-reduction election inside the employer's cafeteria plan. Employees choose an annual amount, fund it pre-tax from payroll, and spend it on eligible expenses. Two quirks matter for plan sponsors. First, the full annual election is available on day one, so an employee who spends $3,400 in January and leaves in February sticks the employer with the difference. Second, forfeitures run the other way: unused balances at year end revert to the plan.
Contribution Limits, 2026 and 2027
- • HSA: $4,400 self-only / $8,750 family in 2026 and $4,500 / $9,000 in 2027, plus a $1,000 catch-up at age 55. Requires a qualified HDHP: minimum deductible $1,700 self-only / $3,400 family in 2026, rising to $1,750 / $3,500 in 2027.
- • Health FSA: $3,400 employee salary reduction for 2026, with up to $680 of carryover if the plan allows it. The IRS publishes the 2027 figure in the fall.
- • HRA: no statutory limit for HRAs integrated with a group plan. The excepted-benefit HRA variant is capped at $2,200 for 2026 and $2,250 for 2027.
- • ICHRA: no dollar limit. Its small-employer cousin, the QSEHRA, does carry indexed annual caps.

Portability and Unused Funds
The second axis that separates the accounts is what happens to a dollar that doesn't get spent.
HSA dollars never expire. They roll over year to year, can be invested, and belong to the employee whether they stay, leave, or retire. This is why HSA contributions read as compensation, not as a plan feature.
HRA dollars behave however the plan document says. The employer chooses whether unused allowances roll over, cap out, or expire at year end, and the balance stays behind when the employee leaves. Because most HRAs pay only as claims come in, an unclaimed allowance often costs the employer nothing.
FSA dollars are use-it-or-lose-it. The plan may soften that with either a carryover (up to $680 for 2026) or a grace period of two and a half months, but not both. Unused amounts beyond that are forfeited to the plan.
When to Choose Each
For most employers this is not a three-way choice. The FSA is a complement that can sit alongside either of the others; the real decision is usually HSA versus HRA as the funding vehicle behind a higher-deductible plan design. A worked example shows the trade.
The same $1,000, two ways
A 100-employee group budgets $1,000 per employee to soften a new deductible. Funded into HSAs, that is $100,000 out the door in January, every dollar owned by employees from day one, including the ones who never see a doctor. Suppose instead the employer promises the same $1,000 through an HRA and members submit claims against 60 percent of it (a figure chosen for illustration, not a benchmark). The employer's actual spend is about $60,000, and unclaimed allowances cost nothing.
The HRA is cheaper in this example; the HSA is worth more to the people receiving it, because it is portable, investable, and theirs. Neither answer is wrong. It is a choice between plan economics and perceived value, and it deserves to be modeled, not defaulted.
Choose the HSA route when
The workforce can absorb a qualified HDHP and will actually use the account. The tax treatment is the strongest of the three, and the recruiting story is better: the contribution is the employee's money. The full case is in our HDHP + HSA strategy guide.
Choose an HRA when
You want to raise the deductible without a qualified HDHP, or you want control: over eligible expenses, over rollover, over whether the benefit follows the employee. HRAs also fit populations where HSA eligibility rules would exclude too many people, such as workforces with heavy Medicare enrollment.
Add the FSA as a complement
An FSA layers onto any group plan design at little employer cost, and payroll-tax savings on employee elections offset much of the administration cost. One compatibility rule to respect: a general-purpose FSA makes an employee ineligible for HSA contributions. Pair HSAs with a limited-purpose FSA (typically dental and vision) instead.
Where ICHRA Fits
The individual coverage HRA, available since 2020, is not a fourth account so much as a different chassis. A traditional HRA sits on top of the employer's group plan. An ICHRA replaces the group plan: the employer sets a tax-free monthly allowance, and employees use it to buy their own coverage on the individual market. There is no dollar cap, and employers can vary the allowance across defined classes of employees, such as full-time versus part-time or by geography, as long as terms are consistent within each class aside from permitted variation by age and family size.
Two mechanics decide whether an ICHRA works. The first is affordability: for 2026, an ICHRA offer is affordable when the employee's cost for the lowest-cost self-only silver plan in their rating area, net of the allowance, stays under 9.96 percent of income for 2026 plan years, or 10.22 percent for 2027. Employers cannot see household income, so for the ACA employer mandate the test runs against the IRS affordability safe harbors: W-2 wages, rate of pay, or the federal poverty line. Household income enters on the employee's side instead. It is the standard behind the premium tax credit, and an affordable ICHRA offer switches that credit off. The second is the local individual market. An allowance buys very different coverage in a metro with ten competing carriers than in a county with one.
The honest fit: ICHRA works best for smaller groups facing steep or volatile group renewals, for workforces spread across many states, and for classes (part-time, seasonal) an employer could not otherwise cover. It is a harder sell for larger groups whose self-funded or experience-rated group program already prices better than the individual market. Fixing the employer's cost as a defined contribution is ICHRA's real appeal, and that logic is worth understanding even if you never leave the group market: it is the same thinking behind a defined-contribution approach to employee contributions.
Key Takeaways
Ownership tells you most of what you need: HSA money belongs to the employee forever, HRA money is an employer promise paid only when claimed, and FSA money is a pre-tax election that expires. The HSA maximizes tax value and portability, the HRA maximizes employer control and economics, the FSA complements either, and ICHRA moves the whole question onto the individual market with a fixed employer contribution. The right answer depends on the plan design underneath and the workforce on top, which is why it should be priced as a scenario, not picked from a chart.
