Criminal Tax Investigations
& Prosecutions

Kostelanetz LLP has long maintained a national and international reputation as one of the country’s preeminent law firms engaged in defending against criminal tax investigations and tax fraud prosecutions. Chambers USA notes that Kostelanetz has a “reputation as an expert tax boutique with significant strength in criminal proceedings,” and one interviewee told Chambers that Kostelanetz is “one of the top tax boutiques in the country.”

That reputation comes from our more than 75-year history of focusing on civil and criminal tax controversies and white-collar criminal defense. Our attorneys possess a unique level of experience, knowledge, training and skill in white-collar and tax controversy matters. Our firm has more experience in criminal tax cases than most large firm white-collar and tax controversy departments. There are very few issues or fact patterns that our attorneys have not already encountered in previous cases involving alleged tax evasion, tax fraud, and other tax-related criminal allegations.

The Kostelanetz team has significant government experience and includes a former Acting Assistant Attorney General of the U.S. Department of Justice (DOJ) Tax Division, a former Chief of the IRS Criminal Investigation Division, four attorneys with criminal and civil DOJ Tax Division experience, a former Special Trial Attorney for the IRS Office of Chief Counsel in New York, and three former Assistant United States Attorneys in the Southern District of New York. As a result, our firm has a unique familiarity with the practices of the IRS, DOJ, and other taxing authorities.

Our firm’s extensive tax experience serves it well in representing clients faced with criminal tax investigations conducted by the IRS, the DOJ Tax Division, local United States Attorneys’ Offices, or state prosecutors, as well as cross-border investigations involving both U.S. and foreign law enforcement agencies. Our attorneys have represented thousands of corporations and individuals nationwide and outside the United States in cases, including allegations of failure to report income, overstated deductions, failure to collect and pay employment taxes, preparation of false returns, failure to file returns, presentation of false documents to the IRS, conspiracy to impede or obstruct the IRS, as well as other tax evasion-related crimes, such as structuring and currency transaction reporting violations.

The firm, overall, is ranked nationwide by legal rankings agency Chambers USA in Tax Controversy, and four of the firm’s attorneys are ranked by Chambers USA for Tax: Fraud nationally. Interviewees remarked to Chambers USA about Kostelanetz:

  • “There’s no better group of people to handle tax controversy matters – they’re very effective and personable.”
  • “They’re tax experts and they have a deep knowledge and thorough understanding of the tax code, but also how the IRS and DOJ are going to approach things.”

The firm also has been recognized as a Tier 1 National “Best Law Firm” in three categories, Tax Law, Litigation – Tax, and Criminal Defense – White-Collar, by U.S. News – Best Lawyers®.
