Flexible Spending Account Guide
Learn how FSAs work, who's eligible, and how to make the most of your employer-sponsored Flexible Spending Account.
What is an FSA?
A Flexible Spending Account (FSA) is an employer-sponsored account that lets you set aside pre-tax money to pay for qualified medical, dental, and vision expenses. FSA contributions reduce your taxable income. For 2025, the IRS contribution limit is $3,300. FSA funds are available in full at the start of the plan year — you don't have to wait for contributions to accumulate. Note that FSAs generally operate on a use-it-or-lose-it basis, though your employer may offer a carryover option or grace period.
