We paid our son's winter 2017 tuition from a 529 plan in November of 2016 (the due date) and the university credited the payment in December 2016. In January 2017, he changed his schedule which resulted in a partial tuition refund from the university in February 2017. We did not reinvest the refunded money into the 529 plan, because we intend to use it toward spring 2017 college expenses. Do I need to report the refund on my 2016 return since the refund was not issued till 2017? (I am the recipient of the 1099-Q)
