Retirement tax questions

No, contact your employer for a corrected W-2.  It will not sort out on it's own.  The IRS gets copy of the W-2 and so does the Social Security Administration.   Your SS tax payments will not get credited to you if the wrong SSN is on the W-2.

If your employer refuses to fix the error, then  contact the IRS for assistance.  

See this IRS topic for an incorrect W-2 if your employer will not correct it.
