Jones Bluff and the Locked Door: Why Partnership BBA Audits Are Now an Even Harder Place to Raise a Due Process Challenge

The Tax Court's decision in Jones Bluff, LLC v. Commissioner, 166 T.C. No. 6 (2026), is the kind of opinion that is easy to misread. Nothing in the decision holds that the centralized partnership audit regime enacted by the Bipartisan Budget Act of 2015 violates the Due Process Clause. Nothing in the decision holds that it does not. What the Tax Court actually decided is that the partnership itself cannot raise a due process claim on behalf of its partners in the partnership-level BBA proceeding, and that the partners' claim is not ripe until the Service actually pushes tax out to them under Internal Revenue Code section 6226. That may sound like a technical jurisdictional point. It is not. It is a practical holding that all but forecloses one avenue for partners to get before a court to challenge the constitutional structure of the BBA regime.

A brief refresher on the statutory architecture is necessary to understand why this matters. Under the prior Tax Equity and Fiscal Responsibility Act regime, partnership items were determined at the partnership level, but the tax was assessed and collected at the partner level. Certain partners, including the tax matters partner and partners above certain ownership thresholds, had statutory rights to notice of proceedings and to participate in them. Congress enacted the BBA in 2015, and it became effective for partnership tax years beginning after December 31, 2017. The architecture changed fundamentally. Under the BBA, the partnership is the entity that owes the tax absent a valid push-out election, and the partnership representative has exclusive authority to bind the partnership and, derivatively, the partners. Individual partners have no right to notice of administrative proceedings and no direct participatory role. They are, in a practical sense, spectators to their own tax exposure.

That structure has always made due process lawyers uncomfortable. Partners bear the economic weight of partnership-level adjustments, but they are functionally locked out of the process that determines those adjustments. In Jones Bluff, the partnership, an LLC treated as a partnership that had claimed a conservation easement deduction under Code section 170, took the logical next step after receiving a Notice of Final Partnership Adjustment. It argued that the BBA regime violates the Fifth Amendment's Due Process Clause because it does not give partners notice or an opportunity to be heard before they are economically affected by partnership-level determinations. The Service moved to dismiss.

The Tax Court sided with the Service, but not on the merits of the constitutional claim. The court held, first, that the partnership could in theory raise a due process claim on its own behalf, but that it lacked standing to raise the rights of its partners. Third-party standing is disfavored generally, and the court concluded that the partners could, at least in theory, raise their own constitutional claims later, in a refund action or during collection proceedings. That was enough to deny third-party standing here. Second, the court held that the partners' claims, to the extent they were the ones really being asserted, were not ripe under Article III. Any injury to the partners was contingent on future events, including whether the partnership ultimately elected to push out under section 6226 or otherwise pass the liability through. Because those events had not yet occurred, the challenge was premature.

The concurrence, representing three judges, went further. It suggested that there would be no viable due process claim at all, relying on TEFRA-era precedent that had upheld the validity of partnership-level proceedings even against non-notice partners. The concurrence treats that precedent as persuasive in interpreting the BBA, notwithstanding the structural differences between the two regimes. A practitioner reading the majority and the concurrence together should come away with a clear message. Bringing a due process challenge inside a BBA proceeding is going to be very difficult, and the receiving judges are likely to be skeptical even when jurisdictional obstacles are cleared.

There is a line of authority that indirectly supports the court's willingness to maintain strict procedural barriers on partners' access to constitutional relief. The Ninth Circuit's en banc decision in Seaview Trading, LLC v. Commissioner, 62 F.4th 1131 (9th Cir. 2023), was a TEFRA case, but its reasoning is instructive. The en banc court held that a partnership's faxing and mailing of a delinquent return to individual Service employees did not constitute a filing sufficient to trigger the three-year statute of limitations. The decision treats the administrative mechanics of partnership tax procedure as exacting and unforgiving, and rejects efforts to loosen those mechanics based on equitable considerations. Jones Bluff is in the same spirit. The BBA is a structural statute. The courts are showing every sign of enforcing it on its own terms, leaving partners to bring their claims, if they can, in the narrow windows the statute leaves open.

What should partnership representatives and partners actually do with this decision? A few practical steps are in order. First, the partnership representative needs to understand, in a way that was not necessary under TEFRA, that he or she has exclusive authority to bind every partner in the partnership. That is not a theoretical proposition. Partners who expect to have any meaningful influence on the outcome of a BBA audit need to build that influence into the operating agreement. Operating agreement provisions should require the partnership representative to provide regular updates, consult on material decisions, obtain approval for certain kinds of settlements, and exercise the push-out election only with partner input. The default BBA regime provides none of this, so the operating agreement has to.

Second, documentation of partner communications is no longer a nicety. It is a structural necessity. If the partnership representative agrees to a settlement that the partners later believe was unfavorable, the partners' only meaningful recourse will be against the partnership representative, and that recourse depends heavily on whether the representative complied with agreed consultation procedures. Well-kept records of communications, approvals, and disclosures are what make those claims live. Without documentation, the partners' ability to police the representative's conduct evaporates.

Third, the push-out election under section 6226 deserves careful, advance planning. A push-out turns a partnership-level liability into a series of partner-level adjustments for the reviewed year, each partner picking up the tax on the partner's own return. That has significant implications. It removes the partnership from the enforcement chain. It subjects each partner's share of the adjustment to the partner's own marginal rate. It may trigger interest computations at different rates than a partnership-level assessment would. And, as Jones Bluff now confirms, it is the event that ripens a partner's due process claim. A partnership representative who approaches the push-out decision without structured analysis is making a major decision with partner-level consequences on the fly, and that is exactly the kind of decision that operating agreements ought to govern.

Fourth, the forum question for any constitutional attack is now a central strategic consideration. Jones Bluff pushes due process claims out of the Tax Court's partnership-level proceedings and into refund litigation or collection actions, which means federal district court or, for collection proceedings, potentially the Tax Court in a different procedural posture. The timing of when to raise the constitutional argument, and in which forum, is a decision that belongs to counsel with experience in federal court tax practice, not something to be decided by whoever happens to be defending the audit. For partners facing large potential exposures from a partnership audit, bringing litigation counsel in early, before the push-out election is made and before the claim has even arguably ripened, may be the difference between preserving the constitutional argument and losing it.

The longer-term trajectory of BBA constitutional litigation is unclear. Some partner will eventually bring a fully ripe claim, in the right forum, with the right factual record, and the courts will have to reach the merits. The shape of that eventual ruling is anyone's guess, but the tea leaves from Jones Bluff are not encouraging for the partner-plaintiff. The concurrence's reliance on TEFRA-era authority is particularly telling, because the BBA was enacted in part because TEFRA had become unworkable, and the courts upholding TEFRA procedure have generally done so on the premise that partner-level remedies were enough to satisfy due process. If the Tax Court is willing to treat those authorities as controlling even under the more restrictive BBA, the merits window is narrower than it might first appear. Jones Bluff is not the last word. It is a procedural door-closing that forces partners to find other doors. For practitioners, the immediate message is that the BBA regime is what it is, that the Tax Court is not going to relax its structure through creative standing or ripeness holdings, and that the real protections for partners have to be built into the partnership documents and audit-management practices from the outset. The time to prepare for a BBA audit is before the first notice arrives, not after.
