For 2025, the maximum contribution limit for a Microsoft healthcare FSA is $3,200. This maximum is per employee, not per household. For example, you and your spouse/domestic partner could each contribute $3,200, even if you both work at Microsoft.
Important Note! Estimate your expenses carefully. The FSAs can only reimburse services you use or items you purchase by December 31 of each year. All claims must be received within 90 days of the end of the plan year.
The IRS allows you to carry over up to $640 in unused General Purpose or Limited Purpose healthcare FSA funds to the following calendar year. Any funds over $640 remaining in your FSA following 90 days after the end of the plan year will be forfeited, as required by IRS rules.
Note: Dependent Care FSAs do not allow for any carryover to the next year.
When you enroll in the FSA, you decide how much to contribute for the year, up to the maximum amount. The amount you elect will be deducted on a prorated basis for each pay period throughout the year to fund your account. You must re-enroll during the open enrollment period each year if you want to continue participating in the next plan year unless you have a carryover from the prior plan year.
