Why choose Kohn, Kohn & Colapinto as your IRS tax fraud lawyers?

Kohn, Kohn & Colapinto’s tax fraud lawyers have successfully represented several IRS whistleblowers and tax evasion whistleblowers, including the largest Internal Revenue Service (IRS) Tax Fraud Whistleblower, Bradley Birkenfeld. Mr. Birkenfeld disclosed illegal offshore Swiss banking that resulted in over $5 billion recovered for U.S. taxpayers. His information forced Switzerland to change its international treaty with the United States. Switzerland’s largest bank was forced to turn over the names of over 4,900 U.S. citizens who held illegal offshore accounts.

What is the IRS whistleblower program?

Tax whistleblowers who provide information about tax fraud or tax evasion to the Internal Revenue Service can receive rewards. The IRS whistleblower must provide information that is specific and credible. If the IRS uses the information provided by a whistleblower in a successful investigation and recovers monetary sanctions, it can award the whistleblower up to 30 percent of the tax, penalties, and interest it collects.

Federal law provides for two types of awards. Internal Revenue Code (IRC) Section 7623(b) provides for rewards of 15 to 30 percent of the amount collected if the taxes, penalties, interest and other amounts in dispute exceed $2 million, and if the case deals with an individual, his or her annual gross income must be more than $200,000. IRC Section 7623(A) provides for a maximum award of 15% for those cases that do not meet the dollar thresholds of $2 million in dispute or cases involving individual taxpayers with a gross income of less than $200,000.
