Just a heads-up warning. You best be *ABSOLUTELY* *POSITIVELY* *UNEQUIVOCALLY* *SURE* that W-2 is wrong. Otherwise, it is you who will pay the price in the end, and it will not be cheap.
In my *very* *limited* experience of claims such as yours, more than 99% of the time the person making the claim is wrong. You've not provided any details on why you believe your W-2 is wrong, so it's impossible for anyone to really help you with this in a viable manner.
However, if the employer is refusing to change it, that's most likely because the employer is right and you are the one who is wrong. The reason I say this is because when you report anything other than what is on your W-2, you also have to show "reasonable effort" to get the W-2 corrected. Then if the employer does not correct it, it is the employer that will pay some fairly hefty finds in the end. Rest assured you're employer knows that. So that's why I question your dissertation that your W-2 is wrong when stated in conjunction with the employer refusing to correct it.
