Case 3-5
IRS Whistleblower and Informing on Tax Cheats
On October 4, 2012, the Internal Revenue Service paid a $2 million reward to a whistleblower that exposed
an alleged tax avoidance scheme by Illinois Tool Works Inc. (ITW) that cost the U.S. Treasury hundreds of
millions of dollars. The scheme involved ITW enlisting a Swiss bank to fabricate unauthorized tax
deductions by duplicating its own tax deductions in order for ITW, as a client and unrelated taxpayer, to
claim the same deductions as an offset to ITW’s otherwise taxable income. As a result of tax audits, ITW
wrote-down its deferred tax asset by $383 million.
Whether motivated by a sense of justice or the pursuit of a seven figure reward, the Wall Street insider
known only as Mr. ABC has demonstrated the huge return on investment available to IRS whistle-blowers
that provide information under a program that pays out between 15 percent to 30 percent of any recovery,
without any monetary cap on the amount of the reward,
It was the third time Mr. ABC had received an IRS whistleblowing award including $1.1 million in 2004
when he provided information about abusive tax shelters that helped Enron avoid taxes on more than $600
million of taxable income. He also received $1.24 million in another case.
In testimony before the 2004 U.S. Senate Finance Committee, Mr. ABC proceeded to explain his
motivation to blow the whistle by criticizing the government’s ability to identify and investigate
sophisticated tax shelters. “When I looked through all the financial engineering and big words, I believed it
was just a fake deduction scheme, he testified.”
The IRS refused to comment noting confidentiality issues.
