Key Takeaways
- Distinguish health FSAs from dependent-care arrangements.
- Choose an election from eligible expenses and the employer plan’s deadlines.
- Check carryover, grace-period and reimbursement provisions instead of assuming unused money remains available.
Before choosing a flexible spending arrangement, identify which kind your employer offers. A health FSA reimburses eligible healthcare costs. A dependent-care arrangement helps with qualifying care that enables work. Their limits and reimbursement rules are different.
Keep the two benefit types separate
| Benefit | 2026 federal amount to check | Main qualification |
|---|---|---|
| Health FSA | Employee salary reductions up to $3,400 | Qualified medical expenses during the coverage period; plan terms apply. |
| Dependent-care assistance/FSA | Generally up to $7,500 excluded from income; $3,750 if married filing separately | Qualifying care enabling work, subject to earned-income and other rules. |
Your employer’s offered limit can be lower. The health FSA amount is an employee salary-reduction ceiling, while the dependent-care figure is a tax exclusion that must be coordinated with employer-provided assistance and the household’s situation. Do not assume both spouses can simply add two full dependent-care exclusions.
Build a health FSA election from predictable costs
Use expected eligible out-of-pocket costs, such as known copayments, dental work or vision expenses, and check them against the plan. Do not include expenses insurance will reimburse, health insurance premiums or amounts you will also reimburse from an HSA.
In a fictional plan, an employee expects $1,300 of eligible expenses and has $200 of administrator-confirmed carryover available for them. An $1,100 election would fill that estimated gap. This is not a recommended amount, and the estimate needs changing if treatment, coverage or carryover availability changes.
For a health FSA, the annual elected reimbursement amount is generally available during the coverage period even before all payroll reductions have occurred. That does not permit reimbursement of care that has not yet been provided. Claims need the required substantiation; a debit-card payment is not a reason to discard receipts.
Ask which unused-balance rule the plan uses
A health FSA is generally use-it-or-lose-it. A plan may offer either a grace period of up to 2½ months or a carryover, but not both for the health FSA. Neither feature is mandatory.
For plan years beginning in 2026, the maximum permitted health FSA carryover is $680, if the plan allows it; a plan may specify less. Do not treat $680 as a guaranteed refund or confuse a 2026 plan-year carryover with the limit applying to an earlier year’s balance.
Write down two dates: the last date on which an expense can be incurred and the deadline for submitting its claim. Ask how a job change or termination affects coverage and claims. Spending on something unnecessary just to use the account still consumes real money.
Check dependent-care eligibility separately
Qualifying care generally must enable you, and a spouse when applicable, to work or look for work. A qualifying person can include a dependent child under 13 when care is provided, or certain people unable to care for themselves. The detailed residence, relationship, filing-status and provider rules matter.
The exclusion cannot exceed applicable earned-income limits, including a spouse’s earned income, with special rules for certain students and people unable to care for themselves. Employer assistance and plan nondiscrimination rules can also affect the result. Confirm reimbursement timing with the administrator rather than applying the health FSA’s annual-availability rule.
Excluded dependent-care benefits reduce expenses available for the child and dependent care credit. The same costs cannot receive both benefits. Have the current-year exclusion and credit calculated together; do not assume the largest FSA election always wins.
Coordinate with an HSA before enrolling
A general-purpose health FSA that reimburses your medical expenses can make you ineligible for HSA contributions. Limited-purpose or post-deductible health FSAs may work differently. A dependent-care FSA is a different benefit; do not confuse its name with medical coverage.
Before open enrollment closes: obtain the plan summary, confirm eligible costs, carryover or grace-period rules, claim deadlines, HSA compatibility and permitted midyear election changes. Save your election confirmation with the calculation you used.
