I don’t actually know the exact details, although the IRS must get much more than just boxes 1 through 6, because the several of the codes in box 12 and the retirement check box 13 can significantly impact your federal tax return. However, box 14 is a general memo field and employers can put anything in that box that they want to. Some items in box 14 are recognized by TurboTax, I think when states have designated certain items be put there.
