Taxpayer Information: Options Exist to Enable Data Sharing Between IRS and USCIS but Each Presents Challenges

摘要

In 2000, federal agencies estimated they saved at least $900 million annually through data sharing initiatives. The Internal Revenue Service (IRS) can use data from taxpayers and third parties to better ensure taxpayers meet their obligations. Likewise, Congress has authorized certain agencies access to taxpayer information collected by IRS to better determine benefit eligibility. In July 2004, we reported that data sharing between IRS and the United States Citizenship and Immigration Services (USCIS) has the potential to improve tax compliance as well as immigration eligibility decisions (GAO-04-972T). For this report, GAO determined (1) the potential benefits of data matching, and (2) the options and associated challenges.
