Deductions & credits

Per the case, Lang v.Commissioner of the Internal Revenue, if you paid the expenses and had no legal obligation to do so, they can be considered a gift from you, and allow your son to deduct the expenses in the year paid. In the Judith Lang case, Ms. Lang's mother paid her medical expenses and real estate taxes.
