EMPLOYEE BENEFITS GUIDE
Health FSA contribution limits set a ceiling on how much you can elect to have deducted from your pay, but your expected expenses should guide the amount you choose. For plan years beginning in 2026, the federal employee salary-reduction limit is $3,400. Your employer’s plan may allow a lower election.
A health flexible spending arrangement, or FSA, can help you pay eligible out-of-pocket health costs with pretax money. Before enrolling, check the applicable plan year, your employer’s rules and the expenses you reasonably expect to incur. These six checks can help you make that decision.
1. Check FSA Contribution Limits for Your Plan Year
The IRS adjusts the health FSA salary-reduction limit for inflation. An enrollment period held in one calendar year may cover a plan year beginning in the next, so check the year on your benefit materials before using a dollar amount.
| Health FSA Rule | Confirmed Amount for 2026 |
|---|---|
| Maximum annual employee salary-reduction election | $3,400 |
| Maximum carryover if the employer’s plan permits it | $680 |
These figures come from IRS Revenue Procedure 2025-32, section 3.15. They apply to 2026; they should not be presented as confirmed 2027 limits. An official IRS announcement of the 2027 health FSA amounts was not verified in the research supporting this article. Before making a 2027 election, confirm the applicable limit with your benefits administrator and the IRS annual inflation-adjustment releases.
2. Confirm Your Employer’s Election Rules
The federal ceiling does not mean every employer offers the same FSA or lets employees elect the maximum. Check the plan’s enrollment instructions for eligibility, the maximum election, the coverage period and the deadline for submitting your choice.
Ask whether the portal expects an annual amount or a deduction per paycheck. Entering the annual figure in a per-paycheck field can create an expensive mistake. Review the confirmation screen and save the completed election so you can compare it with your payroll deductions.
The limit concerns employee salary reductions to a health FSA. IRS Publication 15-B explains the employer’s responsibility to keep elections within the applicable limit. A dependent-care FSA and an HSA have separate rules and should not be combined with this health FSA election.
3. Estimate Eligible Expenses Before Choosing an Amount
Start with costs you expect to pay yourself after insurance. Examples may include eligible medical copayments, dental treatment, prescription expenses and vision care. Confirm the expense with the FSA administrator, especially when treatment has both medical and personal purposes. Insurance coverage and FSA eligibility are separate questions.
Use prior receipts as a starting point, then adjust for changes in your household, coverage and planned care. A large deductible alone is not a reason to elect the maximum if you do not expect to incur that much eligible spending.
Hypothetical budgeting example: You expect $300 in medical copayments, $450 in eligible dental costs, $250 in vision expenses and $200 in prescriptions. That totals $1,200. If the plan spreads a $1,200 election equally over 26 paychecks, the deduction would be approximately $46.15 per paycheck, with a small rounding adjustment. These are illustrative expenses, not ESI plan benefits or a recommendation for your election.
HealthCare.gov’s FSA overview explains the basic reimbursement process and why expected spending matters. Use the IRS revenue procedure above for the confirmed 2026 dollar limits.
4. Account for Employer Funding
Your employer may contribute to the FSA, but that contribution is not automatic. Ask how much is available, when it becomes available and how it affects the amount you need to elect from your own pay.
The employee salary-reduction limit generally does not include employer nonelective contributions, sometimes called flex credits. However, credits that you can choose to receive as cash or a taxable benefit are treated differently. IRS Notice 2012-40 explains this distinction. Confirm how your employer’s arrangement is classified instead of assuming that all funding has the same treatment.
5. Check Family Coverage and HSA Eligibility
The employee health FSA salary-reduction limit does not increase just because you cover a spouse or children. If both spouses are eligible to make separate health FSA elections, each can generally elect up to the applicable limit under their plan. Notice 2012-40 explains the employee-by-employee rule.
Coordinate which account reimburses each expense; the same bill cannot be reimbursed twice. Also check HSA eligibility before electing a general-purpose health FSA. Coverage through your own or a spouse’s FSA may affect your ability to contribute to an HSA. A qualifying limited-purpose arrangement can have different treatment, as explained in Publication 15-B. For the broader comparison, read ESI’s HSA vs. FSA guide.
6. Review Unused Funds and Submission Deadlines
Health FSAs generally follow a use-or-lose rule. Your plan may offer a carryover or a grace period, but neither should be assumed. For 2026, the federal maximum carryover is $680 if the plan permits it; the employer’s terms determine what is actually offered.
A spending deadline determines when an eligible expense must be incurred. A claim-submission deadline determines when you must send the supporting records. Extra time to file a claim does not automatically provide extra time to receive care. ESI’s FSA carryover vs. grace period guide explains those differences in detail.
Frequently Asked Questions
Do I Have to Contribute the Maximum to My FSA?
No. The limit is a ceiling. Choose an amount within your plan’s rules that reflects eligible expenses you expect, any employer funding and the plan’s unused-funds provisions.
Can I Change My FSA Election During the Year?
Changes are restricted. IRS Publication 969 says you can change or revoke an election only when permitted by law and the plan. Ask your administrator whether your situation qualifies and what deadline applies.
Can I Use My Full Annual Election Before All Payroll Deductions Are Taken?
Generally, your elected health FSA reimbursement amount must be available during the coverage period even before all scheduled deductions have been collected. Publication 969 explains this rule. Claims still require eligible incurred expenses and appropriate documentation; future expenses cannot be reimbursed in advance.
Make Your Benefits Election With Clear Information
Before submitting an election, confirm the applicable year’s limit, your plan maximum, employer funding, eligible spending and unused-funds rules. Keep the enrollment confirmation and receipts together.
