Benjamin Z. Eisenstat is a Member in Caplin & Drysdale’s Washington, D.C. office, where he assists individuals and corporations in all manner of civil and criminal tax controversies. Over the past decade, Mr. Eisenstat has helped clients effectively return to tax compliance and move forward with their lives, whether that involves correcting tax issues prior to contact from the government, navigating IRS audits, or defending against criminal investigations.

Mr. Eisenstat has consistently achieved favorable results for his clients. In the criminal context, he has a strong record of persuading the government not to bring forth an indictment.  And when cases have reached the plea and sentencing stage, Mr. Eisenstat has successfully advocated for substantial downward departures and variances from the sentencing guidelines, including a recent case where a client received a non-incarceratory sentence despite a guidelines range of 24 to 30 months in prison. In the civil context, he consistently helps his clients minimize their tax and penalty exposure.  To that end, Mr. Eisenstat recently assisted a captive insurance participant in achieving a full concession from the IRS in a docketed case in the U.S. Tax Court.

Mr. Eisenstat is also active with the American Bar Association’s Section of Taxation. He is currently a Co-Chair of the Civil and Criminal Tax Penalties – Criminal Litigation Sub-Committee.
