IRS watchdog thwarts tax evasion schemes "Never before has one individual affected so many investigations, civil and criminal litigation and court-ordered remedies, than Shauna," said Rae Brousseau, a senior IRS tax analyst. Shauna compiles documentation that stands up in court, coordinates with civil and criminal investigators and prosecutors, and assists counsel in pursuing legal remedies. Since Henline became involved with this IRS program in 2001, Brousseau said she has been directly or indirectly responsible for more than $300 million in penalties assessed against individuals filing frivolous returns, and hundreds of millions of dollars in revenue protected by preventing or recovering claims related to frivolous filings. Before Henline, the IRS did not systematically go after the promoters, who find clients by holding seminars, writing books and marketing themselves on the Internet. Georgia Stefan, an IRS supervisory agent, said Henline "essentially wrote the manual, processes and procedures" that need to be followed for frivolous claims cases, and helped create a system that allows her to detect trends and patterns, and identify major con artists. "Shauna is a national expert on this activity," said Stefan. She created a whole program. Seth Heald, a Department of Justice supervisory attorney, said Henline regularly obtains detailed information and evidence from many sources, secures affidavits, provides critical assistance to attorneys to obtain court injunctions and offers expert testimony in court to help shut down tax evasion schemes. "She is a one-woman team at the IRS," said Heald. Henline has been involved in dozens of cases centered on phony income tax withholding schemes that are based on the redemption theory, which according to proponents, allows taxpayers to access secret U.S. Treasury accounts to satisfy debts, including tax liabilities. In 2011, Henline played a major role in bringing complaints against a Colorado tax preparer who used the redemption theory to make $56 million in fraudulent claims, and a Detroit tax preparer who filed dozens of bogus returns claiming $13 million in fraudulent refunds. Henline also was instrumental in a case against a group of defendants operating tax preparation franchises in a number of cities whose bogus claims resulted in a loss of more than $70 million to the U.S. Treasury. The fraud included filing false returns claiming refunds based on phony W-2 forms; the use of fabricated businesses and business expenses on returns to claim bogus deductions; and claiming fuel tax credits in absurd amounts for customers clearly not entitled to any credits. She has been a pivotal witness at many court cases, including the 2008 criminal trial of actor Wesley Snipes, who declared he had no taxable U.S. income, making the IRS Form 1040 "absolutely the wrong form for me to file." Snipes also claimed taxes withheld were "stolen funds." Henline also investigated a group of Florida men who manufactured and sold worthless "bills of exchange" supposedly drawn on the U.S. Treasury for customers to use in payment of their taxes. Henline said individuals filing frivolous claims often hope to avoid tax payments and secure large refunds, sometimes knowing that the claims are fraudulent. Other times, these individuals are innocent victims in desperate straits who fall prey to unscrupulous promoters. "The promoters are greedy, and that is why I am so passionate about going after them," said Henline. We don't want our Treasury coffers depleted by people who are bilking the government through fraudulent claims, and we don't want tax preparers providing people with bad advice.
