Steve’s 30 years of IRS experience nationally and in the field makes him particularly well-qualified to represent clients with a wide variety of federal tax controversy issues, many of which he has resolved favorably[2] after clients have struggled with the IRS for many years.

With 17 years in private federal tax law practice, Steve has helped clients resolve complex audits, protracted collection proceedings, criminal investigations, and settlement of potentially costly litigation before the U.S. Tax Court.  Steve brings effective resolution to the table, with his knowledge of federal tax law and his “inside experience” with the IRS corporate culture and the inner workings of the IRS as a world-wide organization of 100,000 people.

Steve’s career at the IRS began in 1970 as a tax law specialist with the IRS Office of the Chief Counsel in Washington D.C., where he focused on domestic and international corporate acquisitions and mergers.  He then served as an IRS trial attorney before the U.S. Tax Court before he became a special assistant to the IRS Deputy Chief Counsel where he helped administer a nationwide office employing 5,000 IRS Counsel and Appeals personnel.  In his last Washington position, he maintained close working relationships with the IRS Commissioner’s inner staff, officials and staff at the Treasury Department, the Tax Division of the U.S. Department of Justice, and the Tax Committees  of Congress.

Steve’s Washington, D.C. experience allowed him to take part in key policy, legislative and tax administration matters, while at the same time participating in the review and direction of tax law enforcement and litigation policy for the IRS across the country.

In his 15 years as District Counsel for the IRS Sacramento District, he served as chief legal counsel for all IRS posts of duty in Northern California’s thirty-one counties from the Bay Area throughout the entire northern State.

Steve’s long experience with the IRS and his years of private practice have translated into an ability to obtain favorable outcomes for a wide variety of clients in a number of different areas[3] including voluntary disclosures and offshore compliance, tax evasion, “eggshell audits”, offers in compromise, civil fraud investigations, multiple periods of failure to file, as well as IRS liens and levies.

In the area of offshore compliance, Steve has established himself as an experienced authority. He has published several articles about the IRS’s increasing access to undisclosed taxpayer accounts in tax haven countries. He has assisted over fifty families in obtaining Voluntary Disclosures under the IRS’s 2009 and 2011 OVDI Programs. In 2012, Steve was invited to become a member of the American Citizens Abroad’s Professional Tax Advisory Council (PTAC). American Citizens Abroad (ACA) is the voice of Americans overseas.  ACA is all-volunteer organizations who represent Americans living outside the U.S. to the Executive Branch of the U.S. Government, U.S. Congress, and the U.S. Federal Judiciary.

He was also an adjunct professor of law teaching IRS civil and criminal practice and procedure at the University of The Pacific, McGeorge School of Law for ten years.

Steve is a graduate of Rutgers College and earned his law degree from Boston College Law School, becoming a member of the Massachusetts Bar in 1970, and the District of Columbia bar in 1972. He later got his Masters of Law in Taxation at Georgetown University.

As Steve is not licensed to practice law in California, his practice focuses exclusively on federal tax practice before the IRS and the U.S. Tax Court and does not include California state tax matters. Although Steve is not a member of the California State Bar Association he has been associated with the Taxation Section of the California State Bar since 1986, when he was the IRS Advisor to the Executive Committee where he served until 1994.  Shortly after his departure from the IRS Office of Chief Counsel in 2002, Steve became a public (non-California attorney) member of the Taxation Section Executive Committee where he coordinated events and contacts between IRS officials in Washington, D.C., United States Tax Court officials and judges, and members of the California State Bar Tax Section leadership, between 2005 and 2008.  In addition, Steve was involved in establishing the Taxation Section of the Sacramento County Bar Association.
