Yes, but not exactly. You may NOT count the amount you pay as child support. Room & Board are qualifying expenses for a tax exclusion on the earnings on a 529 plan withdrawal. For students living off campus, the allowable amount is actual cost or the amount charged by the school for on-campus students; whichever is less. For students living at home, the amount allowed is further limited to the amount the school allows for financial aid.
