I just checked W2. No amount of the tuition was included on W2 by my employer. It would also be important to note that none of this tuition involved reimbursement to me. It was paid DIRECTLY to the school from my employer as a partnership program through work where the courses were preselected and I had no say in electives for the grad school program. I guess you could say that all coursework was totally to the benefit of my employer that sponsored this grad school program. Also, my employer was not the school.
