Enter your annual FSA contribution

Enter the amount you plan to contribute to your Flexible Spending Account. The 2025 IRS limit is $3,300. Must be elected during open enrollment and cannot be changed mid-year (except qualifying events).

Select your federal tax bracket

FSA contributions reduce your taxable income dollar-for-dollar. Unlike an HSA, FSA contributions are also exempt from FICA taxes (7.65%) when made via payroll.

Understand the use-it-or-lose-it rule

FSA funds generally must be used by the plan year-end. Some plans offer a $660 rollover or a 2.5-month grace period — check with your employer. Unlike HSAs, FSA funds do not carry over indefinitely.

Suggerimenti

  • Estimate your expected medical expenses carefully. If you over-elect and cannot use the funds, you lose them (except for the $660 rollover).
  • FSAs are fully available from day 1 of the plan year, even if you have not yet contributed that amount. Use this front-loading advantage for large early-year expenses.
  • If you change jobs mid-year, you lose your FSA. Consider this risk before electing the maximum.
  • Dependent Care FSA (DCFSA) provides separate savings for childcare — often missed by families who only think of healthcare FSAs.

What is a Flexible Spending Account (FSA)?

An FSA is an employer-sponsored benefit account for health expenses. Contributions are pre-tax (reducing federal, state, and FICA taxes). The 2025 limit is $3,300. Unlike HSAs, FSAs are 'use-it-or-lose-it' with limited rollover.

What is the difference between HSA and FSA?

Key differences: HSA requires an HDHP and funds roll over indefinitely; FSA works with any health plan but has a use-it-or-lose-it rule (up to $660 rollover in 2025). HSAs can be invested; FSAs generally cannot.

What expenses qualify for FSA?

Qualified medical expenses include: copays, deductibles, prescription drugs, dental and vision care, medical equipment, OTC medications, and many health supplies. FSA funds are available upfront at the start of the plan year.

What is the Dependent Care FSA (DCFSA)?

A separate DCFSA allows up to $5,000/year ($2,500 if married filing separately) for dependent care expenses (daycare, after-school care). This calculator covers the healthcare FSA only.
