I am always interested in learning well-established tax principles. Often, court cases will explicitly indicate that a tax principle is well established or well settled. Or the court may concisely state the holding of a prior case in a parenthetical. Below are excerpts from the April 2026 Tax Court cases referring to these types of principles or holdings.
Barrios v. Commr., T.C. Memo. 2026-32. (Urda)
Du Poux v. Commissioner, T.C. Memo. 1994-448 ("[F]ailure to receive tax documents does not excuse taxpayers from the duty to report income.")
Sawyer v. Commr., T.C. Memo. 2026-33. (Copeland)
