The IRS aggressively pursues taxpayers and promoters involved in abusive offshore transactions. Taxpayers have tried to avoid or evade U.S. income tax by hiding income in offshore banks, brokerage accounts or through other entities. Recently, the IRS provided guidance to auditors on how to deal with those hiding income offshore in undisclosed accounts. The IRS draws a clear line between taxpayers with offshore accounts who voluntarily come forward and those who fail to come forward.
