The IRS reviewed your tax return and found a discrepancy from your return and the information reported to the IRS under your name and Social Security Number (SSN) by employers, banks, or other payers. The IRS needs supporting documents to verify your income, tax credits claimed, income tax withholding or business expenses before your refund will be released or applied as an overpayment to next year’s estimated tax.

The first thing to do is to check the return address to be sure it’s from the IRS and not another agency.

Call the IRS immediately as you may be a victim of tax-related identity theft. Someone else may have used your personal information to file this return. Please complete and sign Form 14039, Identity Theft Affidavit, and mail it to the IRS along with the requested documents. You can find this form online at IRS.gov. You can also refer to the IRS Identity Theft Central resource page for more information
