Which case is cited as the business purpose doctrine: Gregory v. Helvering or Ableman v. Booth?
Gregory v. Helvering Gregory v. Helvering, 293 U.S. 465 (1935), was a landmark decision by the United States Supreme Court concerned with U.S. income tax law.

The doctrine of substance over form is essentially that, for Federal tax purposes, a taxpayer is bound by the economic substance of a transaction where the economic substance varies from its legal form.
