I really did overpay and my employer confirmed this, but my question is, can I file without a corrected W-2 and do I have to file a Form 843 for a return of that excess amount, if my employer is going to refund me without a corrected W-2? They don't want to send a corrected W-2. I honestly don't mind the overpayment, it was less than $25. My biggest concern is consequences, positive or negative, if I don't have a corrected W-2 or file for the refund with an official form.
