You may change an election during the plan year only if 1) a qualified status change (QSC) occurs, 2) the requested change is consistent with the QSC, and 3) you make the change within 30 days of the QSC. For example, your spouse becomes employed and can no longer stay home with the kids. In this case, you may add a Dependent Care Account because child care allows your spouse to work. Qualified Status Changes include changes in legal marital status, number of dependents (birth, adoption, death) and employment status. As noted, election changes must be made within 30 days of the QSC. Because this is an IRS regulated plan, no exceptions can be made.
