CUI Category: Federal Taxpayer Information
Related to returns and return information which are submitted, gathered or generated in conjunction with taxpayers’ responsibilities to comply with federal tax provisions in the United States Code.
“Returns” includes information that is provided to the government pursuant to Title 26, including tax or information returns, declarations of estimated tax or claims for refund. “Return information” includes a taxpayer’s identity, the nature, source or amount of income or any information received by, recorded by, prepared by or furnished to Internal Revenue Service relevant to the determination of tax liability including whether the taxpayer is the subject of investigation. This protection extends to such items as medical, financial and other personal information submitted to the IRS by taxpayers. Standards (typically tolerances, audit criteria and law enforcement techniques) related to the selection of returns for examination should only be disclosed to the extent their disclosure would not impair assessment, collection or enforcement under the internal revenue laws. Tax data originating with the IRS generally retains its confidential status even when it resides with agencies other than the IRS.
