Q.I sold two weeks of vacation time back to my company, which they then deposited the after tax amount to my children’s 529 accounts. Is this considered my contribution, or does my company get to claim these tax benefits?
A. That's considered your contribution, since the money was included in box 1 of your W-2. You essentially paid it. In addition to your W-2, you may want to save a copy of your pay stub for documentation.
