Excerpts from January 2026 Tax Court Cases

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 January 2026 Tax Court cases referring to these types of principles or holdings.

Aventis, Inc. v. Commr., 166 T.C. No. 1 (2026). (Kerrigan)

Grodt & McKay Realty, Inc. v. Commissioner, 77 T.C. 1221, 1237 (1981) (stating that whether a taxpayer experiences the benefits and burdens of ownership of an asset is a question of fact which must be ascertained from the intent of the parties as evidenced by their written agreements)

Aventis, Inc. v. Commr., 166 T.C. No. 1 (2026). (Kerrigan)

In Dirks v. Commissioner, T.C. Memo. 2004-138, aff'd, 154 F. App'x 614 (9th Cir. 2005), the Court declined to apply the substantial compliance doctrine to the statutory 60-day deadline applicable to individual retirement account rollovers under section 408(d)(3)(A) because "the 60-day rule is not regulatory but is found in the statute itself."

Zulfiqar v. Commr., T.C. Memo. 2026-6. (Copeland)

Rodriguez v. Commissioner, T.C. Memo. 2009-22 (ruling that "the IRS has full authority to prepare [a substitute for return] for anyone who fails to file his own return")

Zulfiqar v. Commr., T.C. Memo. 2026-6. (Copeland)

Badaracco v. Commissioner, 464 U.S. 386, 393 (1984) ("[T]he Internal Revenue Code does not explicitly provide either for a taxpayer's filing, or for the Commissioner's acceptance, of an amended return; instead, an amended return is a creature of administrative origin and grace.")

Zulfiqar v. Commr., T.C. Memo. 2026-6. (Copeland)

It is well established that "a settlement stipulation is in all essential characteristics a mutual contract by which each party grants to the other a concession of some rights as a consideration for those secured and the settlement stipulation is entitled to all of the sanctity of any other contract." Saigh v. Commissioner, 26 T.C. 171, 177 (1956).
