Rule of Law:
The validity of a family partnership for federal income tax purposes depends on whether the parties, in good faith and acting with a business purpose, genuinely intended to join together in the present conduct of an enterprise, rather than on a rigid test of whether each partner contributed 'vital services' or 'original capital'.
Facts:
- W.O. Culbertson operated a cattle ranch in partnership with R.S. Coon from 1915 until 1939.
- In 1939, Coon, due to his advanced age and ill health, wished to dissolve the partnership and sell the remaining herd of registered Hereford cattle.
- Coon agreed to sell the herd to Culbertson on the express condition that Culbertson would then sell a one-half interest in the herd to his four sons at the same price.
- Coon's motivation was to preserve the Hereford strain he had developed and his belief that Culbertson was too old to continue the business alone.
- Culbertson purchased the herd and, two days later, sold a one-half undivided interest to his four sons, who in turn gave their father a promissory note for the purchase price.
- An oral partnership, 'Culbertson & Sons,' was formed to continue the cattle business.
- The sons' involvement in the business varied: the oldest was foreman, another was in college and then the army, and the two youngest were in school but worked on the ranch during summers.
- The promissory note was eventually paid off using a combination of credits for an overcharge, gifts from Culbertson, and a loan procured by the partnership itself which was repaid from business proceeds.
Procedural Posture:
- The Commissioner of Internal Revenue determined that the entire income from the 'Culbertson & Sons' cattle business was taxable to W.O. Culbertson, Sr.
- Culbertson petitioned the Tax Court of the United States to challenge the Commissioner's determination.
- The Tax Court sustained the Commissioner's ruling, holding that the sons were not genuine partners for tax purposes.
- Culbertson, as the appellant, appealed the Tax Court's decision to the United States Court of Appeals for the Fifth Circuit.
- The Court of Appeals reversed the decision of the Tax Court.
- The Commissioner of Internal Revenue, as petitioner, was granted a writ of certiorari by the Supreme Court of the United States.

Issue:
Does the validity of a family partnership for federal income tax purposes depend exclusively on whether each partner contributed either 'vital services' or capital originating with them?
Opinions:
Majority - Mr. Chief Justice Vinson
No. The validity of a family partnership for tax purposes is determined by whether the parties genuinely intended to join together in good faith and with a business purpose to conduct an enterprise. The Tax Court erred by misinterpreting this Court's decisions in Commissioner v. Tower and Lusthaus v. Commissioner as establishing a rigid, two-pronged test requiring a partner to contribute either 'vital services' or 'original capital'. Those factors are merely circumstances to be considered in the ultimate inquiry, which is the true intent of the parties. The question is not whether the services or capital meet some objective standard, but whether the partners, considering all facts and circumstances, truly intended to carry on the business together. A promise to contribute services in the future is insufficient to create a partnership for the current tax year, as income must be taxed to him who earns it. Likewise, capital contributed via an intra-family gift can be valid if the donee exercises genuine dominion and control over it; the family relationship is merely a warning to scrutinize the transaction carefully. The case is remanded for the Tax Court to determine the partners' intent based on this broader, fact-based inquiry.
Concurring - Mr. Justice Burton
No. Concurring with the remand, this opinion emphasizes that the facts presented do not, as a matter of law, preclude the Tax Court from finding a valid partnership. A present commitment to render future services is a material consideration to be weighed with all other factors. The physical absence of some sons, for example due to military service, does not automatically negate their status as partners for tax purposes.
Concurring - Mr. Justice Frankfurter
No. The Tax Court misread the Tower decision, but it is important to clarify the correct legal standard. There is no special, unique definition of 'partnership' for tax law that differs from the general common-law concept. The ultimate issue is whether the arrangement is a genuine business venture under familiar partnership principles. Tax tribunals like the Tax Court should be vigilant in piercing sham arrangements created for tax avoidance, but they must do so by applying the correct general rule about what constitutes a partnership, not by creating rigid, tax-specific tests. The core holding of Tower is that the general rule of partnership applies in tax cases.
Analysis:
This case marked a significant shift away from the rigid 'vital services' or 'original capital' test that had emerged from the Tax Court's interpretation of Commissioner v. Tower. By replacing it with a more subjective 'totality of the circumstances' test focused on the parties' bona fide intent, the Court made the analysis more flexible and fact-dependent. This decision made it more possible for genuine family business arrangements, especially those involving gifts of capital or partners with future service commitments, to be recognized for tax purposes. However, it also introduced a degree of uncertainty, as the outcome of a case would now hinge heavily on a fact-finder's subjective determination of the parties' state of mind, rather than on objective criteria.
