Congressional Chief Of Staff Charged With Filing False Security Clearance Form, Imprisoned For Failure To File Taxes

A congressional staffer was charged with filing a false security clearance form, announced Acting Deputy Assistant Attorney General Stuart M. Goldberg of the Justice Department’s Tax Division, U.S. Attorney Jessie K. Liu for the District of Columbia and Assistant Director in Charge Andrew Vale of the FBI’s Washington Field Office.

He was previously sentenced to prison for willfully failing to file an individual income tax return.

According to the indictment, Issac Lanier Avant, a resident of Arlington, Virginia, was a staff member employed by the House of Representatives since approximately 2000.

Since 2002, Avant has been the Chief of Staff for a member of Congress. In December of 2006, he began an additional position for the House Committee on Homeland Security, including Deputy Staff Director and Staff Director.

The indictment charges that from 2008 through 2012, Avant earned wages of approximately $170,000 and failed to file an individual income tax return with the Internal Revenue Service (IRS) during those years.

Avant allegedly had no federal income withheld during those years because in May of 2005, he caused a form to be filed with his employer that falsely claimed he was exempt from federal income taxes. According to the indictment, Avant did not have any federal tax withheld from his paycheck until the IRS mandated that his employer begin withholding in January 2013.

In 2008 and again in 2013, for his position with the Committee on Homeland Security, Avant allegedly completed a Standard Form 86, “Questionnaire for National Security Positions” (SF-86), in order to receive a Top Secret security clearance.

The indictment charges that on Sept. 18, 2013, Avant willfully made a false statement by responding “no” to the following question on a SF-86: “In the past seven (7) years have you failed to file or pay federal, state, or other taxes when required by law or ordinance?”

Despite earning more than $165,000, Avant failed to timely file his 2009 through 2013 individual income tax returns, causing a tax loss of $153,522. Avant did not file tax returns until after he was interviewed by federal agents.

The court imposed a prison term of approximately 4 months, consisting of 30 days incarceration, followed by incarceration every weekend for 12 months.

Avant was also ordered to serve a one-year term of supervised release and to pay restitution in the amount of $149,962 to the IRS.

If convicted, Avant faces a statutory maximum prison term of five years, as well as a term of supervised release and monetary penalties.
