Who needs HSA & FSA administration?
You need an HSA or FSA administrator as soon as you offer any of these accounts, because each one comes with rules that someone has to apply claim by claim and paycheck by paycheck. The usual triggers are adding a high deductible health plan, launching a first FSA at open enrollment, or finding that your current provider's claims, card or payroll file process creates work for HR every week.
The rules differ by account. IRS Publication 969 says an HSA is a tax-exempt trust or custodial account set up with a qualified HSA trustee, and an employee must be covered under a high deductible health plan to contribute. A health FSA is usually funded by salary reduction, is generally use-it-or-lose-it, and needs a written statement from an independent third party for each expense. An HRA is funded solely by the employer. Publication 15-B adds that a cafeteria plan, including an FSA, is a written plan, and that dependent care assistance must be provided under a written dependent care assistance program.
Benefits administration software handles enrollment and elections; an account administrator handles the money after enrollment. If your benefits platform or payroll provider already includes FSA and HSA administration that fits your plan design, a separate administrator may not be needed.
How to choose HSA & FSA administration
Choose on how well the administrator runs the accounts your plan actually includes, how little manual work the claims and payroll file process creates, and how clearly it explains each fee and who pays it.
Bring your plan design to the demo: which accounts you offer, your plan year, grace period or carryover choice, and payroll schedule. Ask the vendor to walk through an enrollment, a card swipe that needs a receipt, and a year-end close for that design.
Account types on one platform
HSA, health FSA, limited-purpose FSA, dependent care FSA and HRA rules differ, and running them on separate vendors means separate cards, portals and payroll files.
HSA custodian arrangement
IRS Publication 969 says an HSA is set up with a qualified trustee, such as a bank, an insurance company or anyone already approved by the IRS to be an IRA or Archer MSA trustee. The administrator you work with may or may not be that trustee.
Card substantiation and claims
Publication 969 requires third-party proof of each health FSA expense; cards can be used if they meet IRS substantiation methods. Weak auto-substantiation turns into receipt requests and suspended cards.
Plan-year rules
A health FSA can offer either a grace period of up to 2 1/2 months or a carryover, and the administrator must apply the option you chose at year-end and through the run-out period.
Payroll contribution files
Salary reductions and employer contributions start in payroll, and file errors become wrong balances, missed HSA deposits and corrections on Form W-2.
Limits and HSA eligibility controls
A cafeteria plan that does not limit health FSA salary reductions to the annual dollar limit is not a cafeteria plan, according to Publication 15-B. Publication 969 adds that an employee covered by a health FSA or HRA that reimburses qualified medical expenses generally cannot contribute to an HSA.

Frequently asked questions
What does an HSA or FSA administrator do?
An administrator runs tax-advantaged spending accounts for an employer. It sets up the plan, receives contribution files from payroll, issues benefit cards, checks that expenses qualify, pays claims, applies the plan-year rules you chose and supports employees. Many also offer HRAs, commuter benefits and lifestyle spending accounts, and some prepare plan documents and run nondiscrimination testing.
What is the difference between an HSA administrator and an HSA custodian?
IRS Publication 969 says an HSA is a trust or custodial account set up with a qualified HSA trustee, which can be a bank, an insurance company or anyone already approved by the IRS to be a trustee of IRAs or Archer MSAs. The trustee or custodian holds the money and reports distributions on Form 1099-SA. An administrator may be the custodian itself or work with one, so ask which applies.
Can employees have an FSA and an HSA at the same time?
Not a general-purpose health FSA. Publication 969 says an employee covered by an HDHP and a health FSA or HRA that pays or reimburses qualified medical expenses generally cannot contribute to an HSA, but an employee can contribute while covered by a limited-purpose health FSA or HRA. A dependent care FSA is a separate benefit for care expenses, not medical ones.
What happens to unused FSA money at the end of the year?
Health FSAs are generally use-it-or-lose-it, according to Publication 969. The plan can offer either a grace period of up to 2 1/2 months after the plan year or a carryover of unused amounts, and the employer is not permitted to refund the balance. HSA balances, by contrast, generally carry over and stay with the employee if they change jobs.
How much can employees put in an FSA?
For plan years beginning in 2026, Publication 15-B says a cafeteria plan may not allow health FSA salary reductions above $3,400 per employee. It also says that for the 2026 tax year the dependent care FSA limit was raised from $5,000 to $7,500, or from $2,500 to $3,750 for married filing separately. Limits change, so confirm the administrator updates them every year.
Can a small business offer an FSA or HSA?
Yes. FSAs are offered through a written cafeteria plan, and Publication 15-B describes a simple cafeteria plan for eligible employers that employed an average of 100 or fewer employees, which is treated as meeting the cafeteria plan nondiscrimination requirements. Publication 969 notes that self-employed persons are not eligible for FSAs or HRAs, so owners should check their own eligibility.
Can an employer contribute to an employee's HSA?
Yes. Publication 969 says an HSA can receive contributions from an employer. Employers that contribute outside a cafeteria plan must make comparable contributions to comparable participating employees, either the same amount or the same percentage of the deductible. Publication 15-B adds that contributions through a cafeteria plan follow cafeteria plan nondiscrimination rules instead, and Publication 969 says they are all reported on Form W-2, box 12, code W.
