Respond to all mail from the IRS immediately. Call the IRS Identity Theft Protection Specialized Unit at 1-800-908-4490. Report the fraud and ask for the IRS ID Theft Affidavit Form 14039. If you are a tax identity theft victim, the IRS may give you a personal PIN number to verify your identity and protect your file going forward.
The Wisconsin Department of Revenue (DOR) has a page on identity theft to help you take steps towards reporting theft and preventing fraud. This year the DOR has implemented a new identity verification tool to check some taxpayers' identity before they can receive a state tax refund. Their identity verification program checks a taxpayer's identity by asking them to take an online quiz or send in documents to prove their identity.
