Plan Highlights
It saves money. Allows you to put aside money tax-free that can be used for qualified medical expenses, even if you or they aren’t covered under a Katy ISD medical plan.
You can contribute between $100 and $3,400 to a healthcare FSA and up to $7,500 to a dependent day care FSA (married filling jointly or single parent) or $3,750 if married filling separately per year through automatic payroll deductions over 24 pay periods.
It’s a tax-saver. Since your taxable income is decreased by your contributions, you’ll pay less in taxes.
The full amount you set aside is available to you on January 1, 2026.
It is flexible. You can use your FSA funds at any time, even if it’s the beginning of the year.
You have to enroll each year.
