The Form 8889 will only report the $4,400 I am contributing pre-tax thru the 125 Plan (the employer contribution made 4/1/17 was reported on 2016 Form 8889), but I am concerned that Box 12 of the W-2 will show an amount in excess of the limit and trigger a problem. Or, is Box 12 just informational and the IRS doesn't pay attention to it?
