You may not change or stop your contributions to the flexible spending accounts during the year unless you have a Qualifying Life Event, such as a birth, marriage or a job loss by your spouse. The change in contributions must be consistent with the Qualifying Life Event. For example, with the birth of a child you can increase your contributions, but not decrease them.
See the “About Your Benefits” section for more information on Qualifying Life Events. If you stop contributing to the flexible spending accounts, you can be reimbursed only for eligible health and dependent care expenses incurred before you stopped contributing.
