The Internal Revenue Service may be missing potential tax dodgers who report their foreign accounts but who avoid paying penalties by not reporting previous years' returns. The Government Accountability Office released Offshore Tax Evasion: IRS Has Collected Billions of Dollars, but May be Missing Continued Evasion (GAO-13-318):Tax evasion by individuals with unreported offshore financial accounts was estimated by one IRS commissioner to be several tens of billions of dollars, but no precise figure exists. IRS has operated four offshore programs since 2003 that offered incentives for taxpayers to disclose their offshore accounts and pay delinquent taxes, interest, and penalties. GAO was asked to review IRS’s second offshore program, the 2009 OVDP. This report (1) describes the nature of the noncompliance of 2009 OVDP participants, (2) determines the extent IRS used the 2009 OVDP to prevent noncompliance, and (3) assesses IRS’s efforts to detect taxpayers trying to circumvent taxes, interests, and penalties that would otherwise be owed.
IRS has detected some taxpayers with previously undisclosed offshore accounts attempting to circumvent paying the taxes, interest, and penalties that would otherwise be owed, but based on GAO reviews of IRS data, IRS may be missing attempts by other taxpayers attempting to do so. GAO analyzed amended returns filed for tax year 2003 through tax year 2008, matched them to other information available to IRS about taxpayers' possible offshore activities, and found many more potential quiet disclosures than IRS detected.
Moreover, IRS has not researched whether sharp increases in taxpayers reporting offshore accounts for the first time is due to efforts to circumvent monies owed, thereby missing opportunities to help ensure compliance. From tax year 2007 through tax year 2010, IRS estimates that the number of taxpayers reporting foreign accounts nearly doubled to 516,000. Taxpayer attempts to circumvent taxes, interest, and penalties by not participating in an offshore program, but instead simply amending past returns or reporting on current returns previously unreported offshore accounts, result in lost revenues and undermine the programs' effectiveness.
