I live in Illinois and have a friend whose cousin out of spite, sent the IRS a letter using my friend's social security number and other personal identification to falsely accuse him of owing $20,000 in unpaid taxes to the IRS. The IRS sent my friend a letter telling him that he had to pay the $20,000, even after my friend denied he sent the letter and sent information to the IRS with his cousin's hand writing to show that the hand writing was indeed his cousin's. I thought the IRS would investigate such a claim more thoroughly. Does this seem plausible, that anyone can write a letter out of spite to the IRS and say you owe money you do not? What should or can he do now? :(
