A TIGTA report has revealed significant flaws in a data-sharing agreement between the IRS and ICE, leading to errors in address verification for over 47,000 individuals. - The agreement allowed ICE to submit names and addresses of immigrants in the U.S.
illegally to the IRS for cross-verification against tax records. - Inconsistent formatting in ICE's data and the IRS's matching criteria led to questionable matches, with incomplete or inaccurate addresses labeled as valid.
- The deal led to the resignation of the then-acting IRS commissioner and has been the subject of multiple lawsuits. - A federal judge previously ruled that the IRS broke the law by disclosing confidential taxpayer information to ICE.
The report did not include any recommendations for improvement.
