What Does This Mean for Limited Partners, LLPs, and LLCs?

In Part 1, we covered the U.S. Court of Appeals for the Fifth Circuit’s decision in Sirius Solutions, LLLP v. Commissioner and the Fifth Circuit’s reasoning for siding with taxpayers over the IRS. The Fifth Circuit held that “limited partner” means exactly what it says: a partner with limited liability under state law. No functional analysis, no passive investor test. Now let’s talk about what this means for you and what you should do about it.

The Immediate Impact: Fifth Circuit Rules the Roost

If you’re a limited partner in a state-law limited partnership (including LLLPs) and you live or operate in Texas, Louisiana, or Mississippi, congratulations: the Fifth Circuit’s decision is binding on you. Your distributive share of partnership income (other than guaranteed payments for services) is not subject to self-employment tax, regardless of how active you are in the business. The IRS must follow this rule in the Fifth Circuit.

The Rest of the Country: Still in the Trenches

Outside the Fifth Circuit, it’s a different story. The Tax Court and the IRS are still applying functional analysis, looking at whether you’re a passive investor or an active participant. If you’re in New York, California, or anywhere else, you’re still at risk of having your limited partner income reclassified as self-employment earnings if you’re too involved in the business. There are similar cases pending in other circuits (notably Soroban in the Second Circuit and Denham Capital in the First Circuit), and a circuit split is now in full bloom.

LLPs and LLCs: Proceed with Caution

Here’s where it gets tricky. The Fifth Circuit’s decision is explicitly limited to limited partners in state-law limited partnerships. The appellate court said it was not deciding whether members of LLPs or LLCs qualify for the exception. That means if you’re a member of an LLP or LLC, you can’t automatically rely on this decision. The IRS and the Tax Court have historically treated LLP and LLC members as subject to self-employment tax, especially if they’re active in the business.

Professional Services Firms: A New Planning Opportunity

For law firms, accounting firms, consulting shops, and other professional services partnerships, this decision is a big deal. Many of these firms are structured as limited partnerships precisely to take advantage of the self-employment tax exception. The Fifth Circuit’s ruling gives these firms in Texas, Louisiana, and Mississippi a clear path to excluding distributive shares from self-employment tax, even for partners who are deeply involved in the business. But beware: the IRS may still challenge aggressive positions, especially outside the Fifth Circuit, and the Tax Court is not bound by this decision in other jurisdictions.

Private Equity and Fund Structures: The Stakes Are High

Private equity, venture capital, and hedge funds often use limited partnership structures, with fund managers holding limited partner interests. The IRS has been targeting these arrangements, arguing that managers who are actively involved should pay self-employment tax on their income. The Fifth Circuit’s decision gives fund managers in the Fifth Circuit a strong argument for excluding their distributive shares, but the issue is far from settled elsewhere. Expect continued IRS scrutiny and litigation in other circuits.

Practical Implications: What Should You Do Now?
For Taxpayers in the Fifth Circuit

Review Your Partnership Agreements: Make sure your limited partners have bona fide limited liability under state law. The Fifth Circuit’s decision turns on legal status, not activity level.

Segregate Compensation: Clearly distinguish between distributive shares (which are excluded from self-employment tax) and guaranteed payments for services (which are taxable). This should be reflected in both the partnership agreement and Schedule K-1 reporting.

Consider Filing Refund Claims: If you’ve paid self-employment tax on distributive shares in open years, you may have a refund opportunity. The statute of limitations is generally three years, so act quickly.

Stay Alert for IRS Appeals: The IRS could seek rehearing en banc or petition the United States Supreme Court. While that’s pending, the Fifth Circuit’s decision is the law in its jurisdiction, but things could change.

For Taxpayers Outside the Fifth Circuit

Proceed with Caution: The Tax Court and IRS are still applying functional analysis. If you’re taking a position based on the Fifth Circuit’s decision, consider making a protective disclosure on Form 8275 to avoid penalties.

Monitor Developments: Watch for decisions in the First and Second Circuits, as well as any Supreme Court action. A nationwide resolution could be coming, but for now, the law is unsettled.

Consult Your Advisors: This is a fast-moving area with high stakes. Work with your tax and legal advisors to assess your risk and plan accordingly.

For LLPs and LLCs

Don’t Assume You’re Covered: The Fifth Circuit’s decision does not automatically apply to LLPs and LLCs. The IRS and Tax Court may still treat members of these entities as subject to self-employment tax, especially if they’re active in the business.

Consider Entity Structure: If self-employment tax is a major concern, you may want to evaluate whether a limited partnership structure is feasible and advantageous under your state’s laws and business needs.

The IRS’s Next Move: Nonacquiescence and Continued Litigation

Don’t expect the IRS to roll over. The agency can “nonacquiesce” in the Fifth Circuit’s decision, meaning it will continue to fight the issue in other circuits and in the Tax Court. The IRS could also seek a rehearing en banc in the Fifth Circuit (though such requests are rarely granted), or petition the United States Supreme Court for review. Meanwhile, the IRS is likely to continue asserting the functional analysis in audits and litigation outside the Fifth Circuit.

The IRS may also issue new guidance or propose regulations to clarify its position. Taxpayers should be prepared for continued uncertainty and potential challenges, especially if they operate in multiple jurisdictions.

Policy and Legislative Considerations: Will Congress Step In?

The Sirius Solutions decision highlights a fundamental tension in the tax code: should self-employment tax apply based on legal form (limited liability) or economic substance (level of participation)? The Fifth Circuit chose form; the IRS and Tax Court prefer substance. Congress could resolve the issue by amending Section 1402(a)(13) to define “limited partner” or adopt a uniform standard. Until then, taxpayers and practitioners are left navigating a patchwork of rules and risks.

The decision also raises broader questions about the taxation of pass-through entities and the appropriate scope of self-employment tax. As business structures evolve and more professionals operate through partnerships, clarity and consistency are more important than ever.

Limitations and Open Questions

Geographic Scope: The Fifth Circuit’s decision is binding only in Texas, Louisiana, and Mississippi. Elsewhere, the functional analysis still applies.

LLPs and LLCs: The decision does not address whether members of LLPs or LLCs qualify for the limited partner exception. The law remains uncertain for these entities.

IRS Response: The IRS may continue to litigate the issue, seek United States Supreme Court review, or issue new guidance.

Legislative Action: Congress could amend the statute to clarify the definition of “limited partner” and resolve the circuit split.

Future Litigation: Similar cases are pending in other circuits. A United States Supreme Court decision may ultimately be needed to achieve nationwide uniformity.

The Bottom Line: Practical, Texas‑Sized Perspective

Here’s the real‑world takeaway, served with a little Texas plain‑speaking:

If you’re a limited partner in a state‑law limited partnership in the Fifth Circuit, Sirius Solutions may offer some favorable footing on how your distributive share is treated. It’s still important to keep your records in good shape and your compensation properly classified.

If you’re outside the Fifth Circuit, the landscape is less settled. The IRS is still on the prowl and the Tax Court is not aligned with the Fifth Circuit’s reasoning (at least not yet).

If you’re operating through an LLP or LLC, things remain even less clear. Guidance is evolving, and the IRS may continue to scrutinize these structures.

For everyone: keep an eye on developments, stay adaptable, and work with professionals who understand the terrain. This is a rare moment when a tax case could actually save you real money or cost you dearly depending on how the details line up.

And when in doubt, remember: here in Texas, we like our statutes plain, our partnerships limited, and just enough uncertainty to keep the IRS agents guessing.

Final Thoughts: Don’t Mess with Texas (or Its Limited Partners)

The Fifth Circuit’s Sirius Solutions decision is a shot across the bow for the IRS and a lifeline for limited partners in the Fifth Circuit. It’s a reminder that, sometimes, the plain language of the law still matters—and that courts can, and will, push back against administrative overreach. But the battle is far from over. The IRS is regrouping, other circuits are weighing in, and Congress may yet step into the fray.

For now, if you’re a limited partner in Texas, Louisiana, or Mississippi, enjoy the win—but keep your boots on. The next round could be just around the corner.
