If you’re a small business leader with 50 or fewer full-time equivalent staff, you’ve likely seen HRA and HSA listed as top low-cost health benefit options for your team, and may have confused the two. Many small employers waste hours researching misaligned options, or accidentally pick a benefit that doesn’t fit their existing health plan offering. This page lays out clear, actionable rules to choose between the two, without overcomplicating your admin workload or stretching your budget.
Two options people mix up
HRAs (Health Reimbursement Arrangements) and HSAs (Health Savings Accounts) are both tax-advantaged tools designed to help employees cover health-related costs, but their core structure and eligibility rules are vastly different. The vast majority of confusion between the two stems from three common misassumptions: first, that both require enrollment in a high-deductible health plan (HDHP), second, that employees keep all unused funds when they leave their role, and third, that the two benefits are always mutually exclusive.
To start with basic definitions: An HRA is an employer-owned account, funded exclusively by the business, that reimburses employees for pre-defined eligible medical costs. A Qualified Small Employer HRA (QSEHRA), the most common HRA type for teams under 50 FTEs, can even be offered as a standalone benefit with no group health plan required. An HSA is an employee-owned account, funded by either the employer, the employee, or both, that is only available to staff enrolled in a qualified HDHP, with no other disqualifying health coverage. Unlike HRAs, HSAs function like personal retirement accounts for health costs, with no use-it-or-lose-it rule for unused funds.
Comparison table
This side-by-side table outlines core differences to help you narrow down your fit quickly:
| Category | HRA (General Purpose / QSEHRA) | HSA |
|---|---|---|
| Account Owner | Employer retains full ownership of all funds | Employee retains full ownership of all funds, including contributions made by the employer |
| Eligibility Requirements | QSEHRAs are only available to employers with <50 FTEs that do not offer a group health plan; other HRA types can be paired with any group plan, no HDHP requirement | Only available to employees enrolled in a qualified HDHP, with no disqualifying coverage (e.g., general purpose HRA, spouse’s general purpose FSA, Medicare) |
| Contribution Rules | Only the employer may contribute; no employee payroll contribution option | Employer and employee may both contribute; combined annual contribution caps apply |
| Use of Funds | Reimburses only eligible costs defined in the employer’s plan documents; QSEHRAs can be used to pay for individual plan premiums | Covers all IRS-qualified medical, dental, vision, over-the-counter medication, and menstrual product costs, with no employer-imposed restrictions |
| Portability | Funds do not travel with the employee when they leave the company; all unused funds revert to the employer | Full account balance (contributions + earned interest) travels with the employee through job changes, retirement, or gaps in employment |
| Tax Treatment for Employers | All contributions are 100% tax-deductible for the business; no payroll taxes are owed on contributions | All employer contributions are 100% tax-deductible for the business; no payroll taxes are owed on contributions |
| Tax Treatment for Employees | Reimbursements for eligible costs are 100% tax-free; unused funds are not taxable as they never belong to the employee | Contributions, account earnings, and withdrawals for eligible costs are all 100% tax-free; non-eligible withdrawals before age 65 incur income tax plus a penalty, after age 65 only standard income tax applies |
| Admin Burden for Small Teams | Low to moderate; QSEHRAs require standardized plan documents, annual employee eligibility notifications, and ongoing tracking of reimbursements to avoid exceeding annual allowable amounts | Low; employers only need to confirm employee HDHP eligibility annually and process pre-tax payroll contributions if employees elect to contribute their own funds; no tracking of employee withdrawals is required |
Illustrative example
Illustrative example: A small independent bookstore with 12 total staff, 7 full-time and 5 part-time, is evaluating health benefit options. Half the staff are already covered by a spouse’s group health plan, while the other half buy individual coverage on the state exchange.
If the owner does not want to implement a group health plan, they could offer a QSEHRA with a monthly contribution of $225 per full-time staff and $110 per part-time staff. Staff on spouse plans can use the funds to cover out-of-pocket costs like copays and prescription drugs, while staff buying individual plans can use the funds to cover their monthly premiums. If the owner later decides to offer a group HDHP as their core health benefit, they could switch to offering an HSA with a $100 monthly employer contribution per staff member, and allow employees to contribute additional pre-tax funds via payroll to cover their annual deductibles and routine care costs. If the owner wants to offer both benefits to maximize value for staff, they could structure the HRA as a limited-purpose plan that only reimburses dental and vision costs, which would not disqualify staff from making HSA contributions.
Limits and exceptions
There are key constraints that apply to both benefits that may eliminate one as an option for your team, regardless of other fit factors.
First, QSEHRAs are only accessible to employers with fewer than 50 full-time equivalent employees that do not offer a group health plan. If you have 50 or more FTEs, you are subject to ACA employer mandate requirements and cannot offer a QSEHRA, though you may offer other HRA types alongside your group health plan. For HSAs, employees are ineligible to contribute if they are claimed as a tax dependent on another person’s return, are enrolled in Medicare, or have access to a general purpose flexible spending account (FSA) via a spouse’s health plan, even if they are enrolled in a qualified HDHP.
Annual contribution limits for both benefits are updated each tax year by the IRS, so confirm current caps with your licensed broker or official IRS guidance before setting contribution amounts. Unused HRA funds can be rolled over to the next plan year at the employer’s full discretion, but there is no requirement to offer rollovers. Unused HSA funds roll over automatically every year with no maximum cap, and employees can invest funds in the account to grow earnings tax-free over time. If you operate in multiple states, check your state department of insurance for any additional local rules that apply to HRA offerings for employees residing out of state.
Bottom line
Use these two paths to make your final decision, no complex calculations required:
Path A: Choose an HRA (most often a QSEHRA for small eligible teams) if you do not offer a group health plan, want full control over unused funds, or have a team with mixed health coverage needs (e.g., some staff on spouse plans, some with individual coverage, some on Medicaid).
Path B: Choose an HSA if you already offer a qualified HDHP as your core group health benefit, want to offer a portable long-term benefit for staff, or want to minimize ongoing admin work after initial setup.
If you want to offer both benefits to maximize support for staff, you can structure your HRA as a limited-purpose plan that only covers dental, vision, preventive care, or post-deductible medical costs to avoid invalidating employee HSA eligibility.
