FSA administration, simplified.
FSA administration comes with real complexity — account type rules, eligibility considerations, carryover mechanics, and participant confusion that flows back to HR.
WEX brings flexible spending accounts into one platform, with compliance support, ecosystem integrations, and a participant experience that makes the benefit work the way it should.



Built for every team
that touches FSA benefits
Every FSA type your
employees may need
Medical, limited, combination, and dependent care FSAs each come with different rules, eligible expenses, and pairing options. WEX supports the full range so employers can offer the right account type for every workforce, without adding administrative complexity.

Medical FSA: broad coverage, available day one
A general-purpose health account that gives participants immediate access to their full annual election, ready to use from day one of the plan year for a wide range of qualified expenses.
- Covers prescription drugs, insurance copayments and deductibles, and qualified medical devices
- Day-one fund availability means participants don’t have to wait for payroll contributions to accumulate
- The most flexible FSA option for employees with recurring or unpredictable out-of-pocket healthcare costs
Limited FSA: designed to pair with an HSA
For employees who want to keep their HSA eligibility intact while still using pre-tax dollars for dental, vision, and preventive care — a limited FSA covers both without the tradeoff.
- Covers qualifying dental, vision, and preventive care expenses
- Compatible with a health savings account — employees preserve HSA eligibility and maximize tax advantages across both accounts
- A practical option for HSA-eligible health plans that still want pre-tax dental and vision coverage


Combination FSA: flexibility as the year progresses
Starts as a limited FSA covering dental and vision, then automatically converts to a full medical FSA once the participant meets the IRS deductible, no action required.
- Covers qualified vision and dental expenses before the plan deductible is met
- Converts automatically to a medical FSA after the deductible threshold. Broader eligible expenses, same account
- Supports employees whose coverage needs change throughout the plan year
Dependent Care FSA: reduce the cost of care
Helps employees lower what they spend on eligible dependent care, from childcare to adult daycare, using pre-tax dollars, with recurring reimbursement that reduces back-and-forth for participants and HR alike.
- Covers childcare (up to age 13), adult daycare, before- and after-school programs, and summer day camp
- Recurring dependent care reimbursement reduces the claim submissions that generate HR questions
- A meaningful, tangible benefit for working families managing predictable, ongoing care expenses
