About John D.
John D. Harrington earned a Bachelor of Science in Political Science and Public Administration from Western Michigan University before completing his Juris Doctor at Michigan State University in 1995. His academic path combined coursework in government and administrative systems with the study of law, a grounding that has informed his later work in federal and tax matters.
After law school, Harrington developed a practice that extends into both state and federal forums. He is admitted to practice in Michigan and Florida and holds admissions to several federal courts, including the U.S. District Courts for the Western and Eastern Districts of Michigan, the Middle District of Florida, and the United States Tax Court. He also maintains credentialing as an Enrolled Agent of the Internal Revenue Service.
Harrington operates his own firm, The Law Office of John D. Harrington, PLLC. As the firm’s owner he handles client work across litigation and administrative settings. His background in public administration and his IRS enrollment inform how he prepares cases for court and negotiates administrative matters.
Litigation in federal court and tax controversies make regular appearances in his docket. He represents individuals and businesses in proceedings before the United States Tax Court and defends or pursues claims in federal district courts where jurisdiction lies. His practice routinely engages issues that cross state lines and involve federal statutes, requiring attention to procedural detail as well as the substantive rules that govern tax law and federal litigation.
Clients and colleagues describe Harrington as methodical in his preparation. He tends to prioritize clear pleadings and careful documentation. The Enrolled Agent credential lets him represent taxpayers before the IRS, and his federal admissions allow him to carry matters into district courts when necessary.
Outside the office, Harrington’s education in public administration still shapes his approach to case management and client communication. He works from an office that bears his name and maintains an active practice in the jurisdictions where he is admitted.
He currently practices from The Law Office of John D. Harrington, PLLC, representing clients in federal and state tax matters, including cases before the United States Tax Court and related federal district court litigation.
