One day, tax law and corporate policy will permit employees to rollover unspent money in a flexible spending account. But not this day. Once again, you must use all of the money in your account by Dec. 31, or forfeit the balance. This is a ridiculous rule that towards the end of each year leads to a run on storable pharmacy products as account holders binge buy things like new glasses, contact lenses, eyewear cleaning products and other qualified products. If you are struggling to exhaust your flexible spending balance, consider loading up on hand sanitizer, cold and flu medications, cough drops, prescription refills, first-aid items like bandages and tape, and common medicine cabinet goods like pain relievers, antacids, heartburn relievers and allergy pills.
