My husband put $2400 into his HSA through Payroll. His W-2 does not show this amount at all. His employer is stating that there was an error when setting it up in their new payroll system and it wasn't set up as a cafeteria plan so therefore should not be put on the W-2 because it was taken out after taxes instead of before. Is this correct? I'm having trouble figuring out how to enter it into TT correctly so he gets credit for putting that money in through payroll and so that he gets credit for already paying that tax amount that he technically shouldn't have.
