Can You Have an FSA and an HSA Together?

You can have an HSA and an FSA at the same time only when the FSA is compatible with HSA eligibility, such as a limited-purpose FSA or a dependent care FSA. A general-purpose health FSA usually disqualifies you from contributing to an HSA while you are covered by it, even if you do not use the FSA or its balance is small. The distinction is about what the FSA is allowed to reimburse, not simply what you intend to spend from it. If your employer offers a limited-purpose FSA, it generally covers dental and vision expenses while your HSA remains available for other eligible health expenses. Confirm the plan type and the timing of any existing FSA coverage before making HSA contributions, particularly if you are changing jobs or health plans.

Why a General-Purpose Health FSA Usually Conflicts with an HSA

To contribute to an HSA, you must meet the applicable eligibility requirements, including having qualifying health coverage and not having disqualifying additional coverage. A general-purpose health FSA can reimburse a broad range of medical expenses, so coverage under one generally conflicts with HSA contribution eligibility. The restriction concerns being covered by the account, not how much you spend or whether you submit claims.

For example, an employee might choose a general-purpose health FSA during open enrollment and later decide an HSA is a better fit. The employee should not assume HSA contributions can begin just because the FSA balance is small or unused. The FSA coverage and its timing matter, so check the plan documents and confirm how the plan is classified before changing payroll elections.

Which FSA Types Can Work Alongside an HSA?

Some FSAs are designed to cover expenses that do not create the same conflict as a general-purpose health FSA. If your employer offers them, these accounts can generally be paired with HSA contributions:

• A limited-purpose FSA, which is generally restricted to dental and vision expenses.
• A dependent care FSA, which reimburses eligible dependent care costs rather than your medical expenses.

Fidelity's HSA-versus-FSA guidance explains that an HSA holder generally cannot fund a general-purpose health FSA but may be able to use a limited-purpose FSA if the employer offers one.

Limited-Purpose FSA for Dental and Vision

A limited-purpose FSA is a common companion account for an HSA holder. It is restricted to certain expenses, generally dental and vision care, rather than covering a broad range of medical costs. That restriction allows the accounts to serve different purposes.

You might use a limited-purpose FSA for expected costs such as eye exams, glasses, contact lenses, or dental cleanings while keeping HSA funds for other eligible expenses. Estimate your likely expenses before choosing a contribution amount. Unused funds may not carry over, and plan coverage rules and deadlines vary by employer.

Dependent Care FSA for Care Costs

A dependent care FSA pays for eligible dependent care expenses, such as daycare or after-school care. It does not reimburse your medical expenses, so it is not the same as a general-purpose health FSA and generally can coexist with HSA contributions.

Keep records for each account and submit an expense only to the account intended to cover it. For more on the account and eligible care costs, see what a dependent care FSA is and which child care expenses may qualify.

How the Accounts Compare

Employers may use different plan names, so rely on the plan documents to determine what an account covers. An account called an FSA is not necessarily a limited-purpose FSA.

What to Confirm Before Enrolling or Changing Contributions

Open enrollment is a good time to clarify your options. A new job, a coverage change, or a change in household benefits can also affect the decision. Before payroll deductions begin, ask your benefits administrator:

• Is the FSA general-purpose, limited-purpose, or for dependent care?
• If it is limited-purpose, which expenses does the plan reimburse?
• Does my health coverage meet the requirements for HSA contributions?
• If I had a health FSA earlier this year, when did that coverage end and how does it affect my HSA eligibility?
• What deadlines and carryover rules apply to the FSA?

Clarifying the account type and coverage dates before making contributions can help prevent an enrollment mistake.

How Job Changes and a Spouse's Benefits Can Affect the Decision

If you leave a job with a general-purpose health FSA and start a new job with HSA-eligible coverage during the same year, do not assume the new employer's plan settles the question. Review when each plan's coverage applies and what type of FSA you had. Your new benefits team can explain its plan details. HSA contributions are also subject to eligibility rules that can depend on your circumstances during the year.

A spouse's employer benefits can matter too. Review the household's coverage and account arrangements together rather than considering each person's elections in isolation. For broader information about HSA access, see whether you can open an HSA on your own.

Considerations for Globally Mobile Employees

Employees transferring to the United States or working temporarily on U.S.-based assignments may encounter FSA and HSA terms for the first time. These accounts are tied to U.S. employer benefit arrangements and eligibility rules, so an account available under one assignment or payroll arrangement may not be available under another.

Before an international move or assignment begins, confirm which benefit plan applies, what type of FSA is offered, and whether you meet the requirements for HSA contributions. The plan documents and benefits administrator can clarify how the employer's arrangements apply.
