On February 27, the Senate Permanent Subcommittee on Investigations (PSI) issued a report and held a hearing related to its multi-year investigation of offshore tax evasion and the DOJ’s efforts to pursue Swiss banks who allegedly aid U.S. citizens in evading taxes. The hearing and report focused on one Swiss bank alleged to have facilitated tax evasion and criticized the DOJ for its supposedly “lax enforcement” approach towards numerous Swiss banks. The report states that U.S. law enforcement authorities have failed to prosecute more than a dozen Swiss banks the PSI staff believes facilitated U.S. tax evasion, and failed to take action against the thousands of U.S. citizens who have been revealed as tax evaders. The report also criticizes Swiss officials who the PSI alleges have worked to preserve Swiss bank secrecy by intervening in U.S. criminal investigations and hampering progress. The PSI report urges the DOJ to “use all available U.S. legal means” to obtain the names of alleged tax evaders, and to hold accountable “tax haven banks that aided and abetted” in the alleged evasion. The report also states that U.S. banking regulators should “institute a probationary period of increased reporting requirements for, or to limit the opening of new accounts by, tax haven banks that enter into deferred prosecution agreements, non-prosecution agreements, settlements, or other concluding actions with law enforcement for facilitating U.S. tax evasion, taking into consideration repetitive or cumulative misconduct.” Finally, the subcommittee recommended that the Senate promptly ratify a pending U.S.-Switzerland tax treaty that would allow for increased sharing of information by the Swiss.
