If your employer offers a Flexible Spending Account (FSA), you may have enrolled to make pretax contributions to it up to $3,400 in 2026 (or a lesser amount set by your employer). The plan then pays or reimburses you for qualified medical expenses. If you also participate in a Health Savings Account (HSA), your FSA can fund only certain permitted expenses. Unlike HSAs, FSAs are use-it-or-lose-it benefits. So you should use your FSA savings by the end of the plan year (typically Dec. 31). However, your employer may provide a 2½-month grace period to use up your contributions or enable you to roll over up to $680 to 2027.
