A letter report issued by the Government Accountability Office with an abstract that begins "As of December 2012, the Internal Revenue Service's (IRS) four offshore programs have resulted in more than 39,000 disclosures by taxpayers and over $5.5 billion in revenues. The offshore programs attract taxpayers by offering a reduced risk of criminal prosecution and lower penalties than if the unreported income was discovered by one of IRS's other enforcement programs. For the 2009 Offshore Voluntary Disclosure Program (OVDP), nearly all program participants received the standard offshore penalty--20 percent of the highest aggregate value of the accounts--meaning the account value was greater than $75,000 and taxpayers used the accounts (e.g., made deposits or withdrawals) during the period under review. The median account balance of the more than 10,000 cases closed so far from the 2009 OVDP was $570,000. Participant cases with offshore penalties greater than $1 million represented about 6 percent of all 2009 OVDP cases, but accounted for almost half of all offshore penalties. Taxpayers from these cases disclosed a variety of reasons for having offshore accounts, and more than half of them had accounts at Swiss bank UBS."
