Federal and InternationalTaxation 

Our federal and international tax litigation practice includes diverse U.S., and international  industries   involving domestic and international tax issues in the areas of income, estate and gift, excise,  employment, and tax-exempt entities.
We represent taxpayers before the Internal Revenue Service (IRS), U.S. Treasury Department, and  U.S. Department of Justice in resolving tax disputes.  Further, we litigate tax controversies  in the U.S. Tax Court, the U.S. Court of Federal Claims, federal district courts,  and  the United States circuit courts of appeal.

With our extensive knowledge of the Internal Revenue Service's (IRS) procedures and practices, we use an effective approach in solving the controversies before proceeding further.  However, if the cases proceed to trial, we are dedicated to aggressively representing our clients' best interests.

Further, we represent our clients both within the United States and internationally by structuring transactions, forming joint ventures, drafting and negotiating contracts, leases and loan documents.  Providing advice and counseling with respect to acquisitions, sales, construction and financing for both domestic and international projects, working with financing and equity organizations such as the International Finance Corporation, OPIC, the European Bank for Reconstruction and Development, and the World Bank.  


IRS has a criminal investigations unit to which all suspected criminal violations are referred for investigation.  Once the investigation is complete, a recommendation is made whether or not to prosecute.  Effective counsel during an on-going criminal tax investigation is an essential safeguard against overzealous prosecution by the Internal Revenue Service (IRS).

We have the knowledge and expertise to represent U.S., and international corporations, individuals, managers, financial officers, executives, and business owners in a broad range of federal and international tax matters. Whether we are representing a client who is under investigation or one who has already been charged with tax fraud, we perform an  exhaustive review of the case to provide a vigorous defense on our client's behalf.  When a case is still in the investigation stage, we do our best to gather and present evidence that halts the case from proceeding further.  We work with forensic accountants and other experts in pursuit of that goal.  When charges have already been filed, we prepare meticulously for the possibility of trial.
