Diane Lynn Kroupa (born October 12, 1955)^[1] is an American attorney who served as a federal judge of the United States Tax Court from 2003 until 2014. Kroupa previously was the Chief Judge of the Minnesota Tax Court. Following her criminal conviction in U.S. District Court for a tax-related crime (conspiracy to defraud the United States), she was sentenced to 34 months in prison. She has since been released from prison.^[2]

Kroupa received a Bachelor of Science in Foreign Service from the Georgetown University Edmund A. Walsh School of Foreign Service in 1978, followed in 1981 by a J.D. from the University of South Dakota School of Law.

Prior to appointment to the Tax Court, Kroupa worked for the Internal Revenue Service as attorney-advisor, Legislation and Regulations Division, Office of Chief Counsel. She also worked at the Tax Court prior to her appointment as an attorney-advisor to Judge Joel Gerber from 1984 to 1985. Kroupa practiced tax law at Faegre & Benson, LLP in Minneapolis, Minnesota. She became a Minnesota Tax Court Judge from 1995 to 2001 and was Chief Judge from 1998 to 2001.

She was appointed by President George W. Bush as a Federal Judge on the United States Tax Court, on June 13, 2003, for a term ending June 12, 2018.^[3] Although under the Internal Revenue Code section 7447 Kroupa didn't serve the sufficient amount of time (15 years) and was under 65 (minimum retirement age) she retired rather than resigned from the Tax Court on June 16, 2014. If she had resigned she would not be entitled to collect her salary for life. Retired judges collect full salary for life.

On April 4, 2016, Kroupa and her husband, Robert E. Fackler, were indicted^[4] on "conspiracy, tax evasion, making and subscribing false tax returns and obstruction of an Internal Revenue Service (IRS) audit" as a "result of an investigation conducted by the Criminal Investigation Division of the IRS and the United States Postal Inspection Service."^[5][6]

On October 21, 2016, Kroupa pled guilty to conspiring to defraud the United States for $450,000 in taxes.^[7] In June 2017, Kroupa was sentenced to 34 months in prison and ordered to pay more than $450,000 in restitution.^[8]
