Harold Levine, the former chair of the tax practice group at Herrick, Feinstein, and a co-defendant pleaded guilty to charges that they failed to report collectively more than $4 million in income to the Internal Revenue Service, according to the Southern District U.S. Attorney's office.

Levine, who was with Herrick Feinstein from 2003 to 2012, and Florida-based accountant Ronald Katz, each pleaded to one count of corruptly endeavoring to obstruct and impede the IRS, and one count of tax evasion. They face potential maximum prison terms of eight years.

“As tax professionals, both Harold Levine and Ronald Katz well knew their obligations to report their income to the IRS. As they have now admitted, they instead engaged in a corrupt scheme to evade taxes on millions of dollars of income,” Acting U.S. Attorney Joon Kim said in a statement Monday. “Now both defendants will be held to account for their crimes.”
