FSA Basics and Strategy
A Healthcare Flexible Spending Account lets you set aside pre-tax dollars for medical expenses, reducing your federal income tax, state income tax, and FICA taxes. The catch: it is use-it or lose it' — funds you do not spend are forfeited (unless your plan offers a rollover or grace period).
The key strategy is to estimate your annual medical spending as accurately as possible. Include recurring costs like copays, prescriptions, dental cleanings, vision exams, and glasses/contacts. Add any planned procedures. Then elect an amount close to — but not exceeding — that estimate.

Frequently Asked Questions
What is the FSA contribution limit for 2026?
The 2026 Healthcare FSA contribution limit is $3,300. Your employer may set a lower limit. Some plans allow a $640 rollover of unused funds to the next year, or offer a 2.5-month grace period — but not both.
What happens to unused FSA money?
Under the use-it-or-lose-it rule, unused FSA funds are forfeited at the end of the plan year — unless your employer offers either a rollover (up to $640 in 2026) or a 2.5-month grace period. This is why right-sizing your election is important.
