Fifth Circuit Rejects 15.3% IRS Tax Test for Limited Partners in Sirius Solutions
1 articles · Updated · Forbes · Jun 11
Summary
The Fifth Circuit ruled in Sirius Solutions that Section 1402’s limited-partner exception turns on statutory text and legal rights, not mainly on how actively a taxpayer participates in the business.
That undercuts the IRS’s functional approach, which had gained traction in Soroban and Denham Capital by arguing active partners should face self-employment tax despite limited-partner labels.
Foreign partnership investors could gain new defenses because the ruling emphasizes limited liability and ownership status—potentially relevant to structures in Cayman, Luxembourg, Ireland and Germany’s KG.
The decision stops short of blessing every limited-liability owner, and it does not resolve treatment of foreign LLCs, U.K. LLPs or check-the-box entities that elect partnership status.
Sirius binds only the Fifth Circuit for now; pending appeals in the First and Second Circuits could create a split and set up Supreme Court review.
A court ruling lets active partners skip self-employment tax. Will the Supreme Court be forced to intervene?
Can your legal title as a 'limited partner' now shield you from the 15.3% self-employment tax, regardless of your workload?

Overview
On January 16, 2026, the Fifth Circuit Court of Appeals issued a pivotal decision in the Sirius Solutions, LLLP v. Commissioner case, fundamentally changing how 'limited partner' status is determined for self-employment tax exemptions. Instead of focusing on a partner’s actual involvement or management role in a partnership, the court shifted the standard to rely on the partner’s legal limited liability status under state law. This move away from the previous activity-based, functional analysis provides a clearer and more objective rule, with immediate and significant implications for taxpayers in the Fifth Circuit.
