Should we offer an HSA or an FSA? What’s the difference?

HSAs and FSAs both offer employees a tax-advantaged way to pay for healthcare expenses, but their differences can have a meaningful impact on how employees use and value these benefits.

Health Savings Account (HSA)

An HSA is available to eligible individuals covered by an HSA-qualified high-deductible health plan (HDHP).

The account offers several important advantages:

• Employee ownership: The account belongs to the employee, even if they change jobs or retire.
• Annual rollover: Unused funds carry forward from year to year without forfeiture.
• Employer contributions: Employers can contribute to help employees offset healthcare expenses and higher deductibles.
• Long-term savings: Employees can accumulate funds for future healthcare expenses, with investment opportunities available through some HSA providers.

Flexible Spending Account (FSA)

A healthcare FSA can be offered alongside many traditional health plans, allowing employees to set aside pre-tax dollars for eligible healthcare expenses.

Unlike an HSA, a healthcare FSA is generally subject to use-it-or-lose-it rules. Unused funds may be forfeited at the end of the plan year, although employers may choose to offer an IRS-permitted grace period or limited carryover.

FSAs can be particularly useful for employees who anticipate regular healthcare expenses and want to reduce their taxable income while managing those costs.

Which option makes more sense?

The better question isn't necessarily, "Which account is better?" It's "Which one best supports our benefits strategy and our employees?"

For some employers, an HSA is an excellent way to encourage long-term healthcare savings while helping employees manage the higher out-of-pocket exposure associated with certain health plans.

For others, an FSA provides greater flexibility because it can accompany health plans that aren't HSA eligible.

Employers can also offer both, although employees generally cannot contribute to an HSA while covered by a traditional general-purpose healthcare FSA. A properly designed limited-purpose FSA can provide an HSA-compatible alternative.

At MPOWR, we evaluate the entire picture—plan design, workforce demographics, employer contributions, and financial goals—to determine which approach makes the most sense.

The objective isn't simply to offer another account. It's to help employees manage healthcare costs in a way that supports your organization's overall benefits strategy.
