It could have been a simple data entry error on the other person's behalf and not necessarily fraud ... the IRS compares your SS#, year of birth and the first 4 letters of your last name with the SSA records ... so if the other person entered on digit wrong in the SS# or year of birth or misspelled their last name this can happen. All you can do is mail in the return this year.
And if you have not yet done so ...
Once you receive a SSN, you must use that number for tax purposes and discontinue using your ITIN. You must also notify the IRS that you have received the SSN (see below).
It is improper to use both the ITIN and the SSN assigned to the same person to file tax returns. It is your responsibility to notify the IRS so we can combine all of your tax records under one identification number.
If you do not notify the IRS when you are assigned a SSN, you may not receive credit for all wages paid and taxes withheld which could reduce the amount of any refund due.
You can visit a local IRS office or write a letter explaining that you have now been assigned a SSN and want your tax records combined.
Include your complete name, mailing address, and ITIN along with a copy of your social security card and a copy of the CP 565, Notice of ITIN Assignment, if available. The IRS will void the ITIN and associate all prior tax information filed under the ITIN with the SSN.
