Employment-Related Identity Fraud: Improved Collaboration and Other Actions Would Help IRS and SSA Address Risks, Report to the Committee on Finance, U.S. Senate [open pdf - 5MB]
From the Highlights: "Employment-related identity fraud poses risks to IRS's [Internal Revenue Service] ability to collect taxes owed on wages and to SSA's [Social Security Administration] ability to correctly calculate and manage Social Security benefits. GAO [Government Accountability Office] was asked to review employment-related identity fraud. This report examines (1) the potential scope of employment-related identity fraud, including what IRS knows about this type of fraud and what GAO could determine by analyzing Department of Health and Human Services' National Directory of New Hires (NDNH) and IRS data; (2) SSA and IRS actions to detect and deter this fraud as well as notify victims; and (3) SSA and IRS's collaboration on the issue."
