A report from the Taxpayer Inspector General has highlighted significant issues with the reliability of IRS taxpayer data used by U.S. Immigration and Customs Enforcement (ICE) for immigration enforcement. The report indicates that the IRS provided addresses for nearly 47,000 individuals to ICE as part of a data-sharing agreement initiated during the Trump administration's intensified deportation efforts. However, it found that ICE did not adhere to the necessary safeguarding standards for handling confidential taxpayer information. The evaluation revealed that the IRS's automated process for matching taxpayer data with ICE records was inconsistent and failed to accurately identify all records that should have been rejected. Although the IRS stated that it improperly shared address data in less than five percent of cases, the report criticized the inadequacy of the rejection process. Additionally, ICE's request for tax information is currently the subject of at least two lawsuits, with a U.S. District Court blocking further sharing of taxpayer information with the Department of Homeland Security. Notably, the inspector general did not recommend any corrective actions in the report, raising further questions about the future of such data-sharing practices.
