FIFTH CIRCUIT EXPANDS LIMITED PARTNER EXCEPTION FOR SELF-EMPLOYMENT TAX
On April 1, 2026, the Internal Revenue Service (IRS) filed a petition for a rehearing en banc in the case of Sirius Solutions LLLP v. Commissioner, No. 24-60240 (5th Cir.), which addresses the scope of the limited partner exception under Section 1402(a)(13) of the United States Internal Revenue Code (Code).
I. Background and Procedural Posture
Sirius Solutions, LLLP (Sirius), a Delaware limited liability limited partnership, operated a consulting business whose income was derived primarily from the services of its partners. Although certain partners were designated as “limited partners” under state law, it was undisputed that they actively managed the business, exercised control, supervised employees, and devoted full-time efforts to the enterprise.
For tax years 2014 through 2016, Sirius excluded the distributive shares of these partners from self-employment income, reporting zero net earnings subject to self-employment tax. The IRS challenged this treatment, asserting that the partners’ active involvement rendered their income subject to self-employment tax notwithstanding their state-law classification.
The United States Tax Court, relying on its prior decision in Soroban Capital Partners, LP v. Commissioner, applied a functional analysis and held that the partners were not “limited partners” within the meaning of Section 1402(a)(13). The Fifth Circuit (Court) reversed in a split decision.
We hereby highlight the Fifth Circuit’s decision.
II. Court’s Opinion
- Majority Opinion: The Fifth Circuit majority adopted a formalistic, state-law-based interpretation of Secction 1402(a)(13). It held that a “limited partner” for purposes of the statute is any partner who holds limited liability under state law, regardless of whether the partner actively participates in the management or operation of the partnership. Under this approach, the statutory exclusion applies broadly to partners in limited partnerships or similar entities who are classified as limited partners, even if they perform substantial services and exercise significant control. The majority rejected the Tax Court’s functional analysis, favoring a rule that emphasizes administrability and reliance on state-law designations.
- Dissent: Judge Graves dissented, arguing that the majority’s interpretation contravenes the text, structure, and historical context of Section 1402(a)(13). The dissent emphasized that, at the time of enactment in 1977, a “limited partner” was universally understood to be a passive investor who did not participate in management and whose limited liability was contingent on such non-participation. The dissent further contended that the majority’s reliance on state-law classifications improperly incorporates evolving state-law concepts into federal tax law, contrary to established Supreme Court precedent. It also highlighted that the statutory distinction between distributive shares and guaranteed payments reflects Congress’s intent to tax income derived from services, regardless of formal labels.
The case has substantial fiscal implications, as the IRS has indicated that similar disputes involve hundreds of millions of dollars in potential tax revenue. Moreover, the decision introduces tension among courts and increases the likelihood of further appellate review, particularly in light of similar cases pending in other circuits.
