Kings Road Property, LLC v. Commissioner: Equitable Tolling Saves Untimely Petition in BBA Partnership Audit

The $15.7 Million Mistake: How a Misplaced FPA Nearly Cost a Partnership Its Day in Court

The United States Tax Court has just handed down a landmark ruling that could reshape how partnerships challenge IRS audit adjustments—one that hinged on a $15.7 million tax deficiency and a misplaced Final Partnership Adjustment (FPA). In Kings Road Property, LLC v. Commissioner, 167 T.C. No. 11 (Sept. 21, 2026), the court held that the 90-day deadline under § 6234(a)—the statutory window for filing a petition contesting a partnership adjustment—is not jurisdictional and may be equitably tolled. The decision marks the first time the Tax Court has explicitly applied equitable tolling to the Bipartisan Budget Act of 2015 (BBA) partnership audit deadlines, signaling a potential shift in the court’s approach to procedural defenses in high-stakes partnership litigation.

The stakes could not have been higher. The IRS had determined that Kings Road Property, LLC and its manager, Kings Road Manager, LLC, owed $11.3 million in tax plus $4.4 million in penalties—a total exposure of $15.7 million—stemming from adjustments to partnership items under the BBA regime. The partnership’s untimely petition, filed just days after the 90-day deadline had technically passed, was saved only by the court’s recognition that the IRS had misled its counsel about whether an FPA had even been issued. The ruling underscores a critical tension in modern tax administration: when procedural missteps by the IRS—even those involving internal mailing errors—can derail a taxpayer’s right to judicial review.

The implications are profound. For partnerships navigating the BBA’s centralized audit regime, the decision suggests that jurisdictional rigidity may yield to equitable considerations when the IRS itself contributes to a taxpayer’s delay. It also raises questions about whether other BBA deadlines—long assumed to be absolute—might similarly be subject to judicial leniency. As the Tax Court wades into uncharted territory, Kings Road may well become the first of many cases testing the limits of equity in partnership audit disputes.

The Calendar Conundrum: How a Simple Address Abbreviation Led to a Procedural Nightmare

The IRS’s failure to update its records with a single address change—reduced to a mere abbreviation—unraveled a meticulously calculated deadline for Kings Road Property, LLC (Kings Road), setting the stage for a procedural showdown that could redefine how partnerships navigate the Bipartisan Budget Act of 2015’s (BBA) audit regime. The stakes were nothing short of $15.7 million in proposed tax adjustments, but the real battle began with a misplaced "Ste" instead of "Suite" in the IRS’s database.

The saga unfolded against the backdrop of the BBA’s centralized partnership audit regime, which replaced the old TEFRA system with a streamlined process where adjustments are made at the partnership level. Under Section 6221, the IRS conducts audits at the partnership level, and any resulting adjustments are assessed against the partnership itself unless a "push-out" election is made under Section 6226. The BBA’s procedural rules, codified in Sections 6221–6241, impose strict deadlines for taxpayers to respond to IRS notices, including the 90-day window to file a petition in the Tax Court after receiving a Notice of Final Partnership Adjustment (FPA) under Section 6234(a). For Kings Road, the clock started ticking on May 24, 2024, when the IRS issued a Notice of Proposed Partnership Adjustment (NOPPA) disallowing a $30.57 million conservation easement deduction.

Kings Road’s troubles began with a NOPPA that arrived at the correct address—100 Bull Street, Suite 212, Savannah, Georgia 31401—but the IRS’s records reflected the address as "100 Bull Street, Ste 212." The discrepancy was more than a typographical error; it was a procedural landmine. The IRS’s own regulations under Section 6231(a)(7) define a partnership’s "last known address" as the address shown on the most recently filed return unless the IRS has been given clear and concise notification of a different address. The BBA’s centralized audit regime hinges on the IRS’s ability to communicate effectively with the partnership representative (PR), and a failure to update the address could toll the deadlines that govern the entire process.

On May 24, 2024, the IRS mailed the NOPPA to Kings Road and its PR at "100 Bull Street, Ste 212." The NOPPA proposed to disallow the $30.57 million deduction, impose an imputed underpayment of $11,310,900, and assess an accuracy-related penalty of $4,395,748. Kings Road did not file a modification request under Section 6225(c), leaving the IRS with a clear path to issue an FPA within 330 days under Section 6235(a)(3). The clock was ticking, and Kings Road’s new counsel, retained after the NOPPA’s issuance, was watching closely.

The BBA’s Section 6235(a)(3) sets a 330-day deadline for the IRS to issue an FPA after a NOPPA is mailed, barring any modification requests. Kings Road’s counsel calculated the deadline as April 21, 2025—330 days from the NOPPA’s issuance—accounting for the weekend rule under Section 7503, which extends deadlines falling on a Saturday or Sunday to the next business day. From the mailing of the FPA, the IRS’s regulations under Section 6234(a) provide a 90-day window to file a petition in the Tax Court. Counsel marked July 20, 2025, as the deadline, assuming the FPA would be mailed by April 21, 2025.

But the IRS never sent the FPA. On March 25, 2025, the IRS mailed the FPA to "100 Bull Street, Ste 212," the same abbreviated address used for the NOPPA. The FPA was returned as undeliverable, and the IRS’s records showed no activity on Kings Road’s account since the power of attorney was filed in August 2024. When Kings Road’s counsel called the IRS on May 21, 2025, an agent confirmed that no FPA had been issued. The IRS’s failure to update its address records with the clear and concise notification provided by the power of attorney—filed on August 27, 2024—left Kings Road in a procedural limbo.

The IRS’s reliance on an outdated address, despite the power of attorney update, raised questions about the agency’s due diligence under the BBA’s regime. The IRS’s own Delegation Order 150-10 delegates authority to the LB&I Division to issue FPAs, but the order does not absolve the IRS of its obligation to communicate with the PR at the correct address. The BBA’s procedural rules are designed to ensure finality, but they also require the IRS to act with precision. A misplaced "Ste" instead of "Suite" exposed a chink in the IRS’s armor, one that could have far-reaching implications for how partnerships challenge untimely notices.

Kings Road’s counsel, believing the FPA had not been issued, filed a protective petition on July 9, 2025—well within the 90-day window they had calculated. The petition arrived before the IRS could reissue the FPA, but the IRS moved to dismiss for lack of jurisdiction, arguing that the petition was untimely under Section 6234(a). The IRS’s position hinged on the argument that the 90-day deadline is jurisdictional, a claim that has gained traction in recent cases like Boechler, P.C. v. Commissioner, where the Supreme Court held that certain tax deadlines are jurisdictional and not subject to equitable tolling.

Yet Kings Road’s case presented a twist: the IRS’s own failure to update its address records may have contributed to the delay. The IRS’s last known address standard under Section 6231(a)(7) requires clear and concise notification of a change, and the power of attorney filed in August 2024 should have triggered an update. The IRS’s reliance on an outdated address, combined with the undeliverable FPA, created a scenario where the procedural rigidity of the BBA collided with the equitable principles that often guide tax litigation. As the Tax Court prepares to weigh in, the question is not just whether Kings Road’s petition was timely, but whether the IRS’s procedural missteps should toll the deadlines that govern the BBA’s centralized audit regime.

The Battle of the Deadlines: Petitioner vs. IRS on Jurisdiction and Equity

The IRS’s insistence that Kings Road’s petition was untimely under section 6234(a)—which grants partnerships just 90 days to challenge a Notice of Final Partnership Adjustment (FPA)—collided head-on with the partnership’s claim that the deadline should be equitably tolled due to the agency’s procedural missteps. The dispute hinged on whether the 90-day window is a jurisdictional bar or a flexible deadline subject to equitable principles, and whether the IRS’s mailing errors, misinformation, and alleged failure to exercise due diligence justified tolling. At stake was not just Kings Road’s ability to challenge a $11,310,900 imputed underpayment and a $4,395,748 accuracy-related penalty, but the broader question of whether the Tax Court would defer to the IRS’s rigid interpretation of BBA deadlines or embrace a more taxpayer-friendly approach.

Kings Road’s arguments centered on four pillars of alleged procedural failure by the IRS. First, it contended that section 6234(a) is not jurisdictional, arguing that the Tax Court has discretion to toll the deadline under equitable principles when extraordinary circumstances prevent timely filing. The partnership pointed to Big Apple Tompkins Realty LLC v. Commissioner, No. 19040-23, 167 T.C. (Aug. 5, 2026), a recent Tax Court opinion that rejected the IRS’s jurisdictional argument in a nearly identical BBA partnership audit dispute. Second, Kings Road asserted that the FPA was not properly mailed because the IRS sent it to an outdated address—“100 Bull Street, Ste 212”—despite Kings Road’s partnership representative having retained new counsel in August 2024, which should have triggered an address update in the IRS’s Centralized Authorization File (CAF) system. Third, the partnership claimed the IRS failed to exercise due diligence by not verifying the correct address before mailing the FPA, particularly after Kings Road’s counsel explicitly inquired in May 2025 and was told there had been “no activity” on the account since the power of attorney was filed. Finally, Kings Road argued that the FPA was invalid because it was signed by a Technical Services Passthrough Coordinator (TSPC) who was not properly appointed under the Federal Vacancies Reform Act of 1998 (VRA), enacted as part of the Omnibus Consolidated and Emergency Supplemental Appropriations Act, 1999, Pub. L. No. 105-277, div. C, § 151(b), 112 Stat. 2681, 2681-611 (codified as amended at 5 U.S.C. § 3345(a)), which governs temporary appointments to Senate-confirmed positions.

The IRS, in contrast, mounted a defense rooted in statutory rigidity and administrative finality. It argued that section 6234(a) sets a jurisdictional deadline, meaning the Tax Court lacks authority to consider a late petition regardless of equitable considerations. The agency relied on Boechler, P.C. v. Commissioner, 142 S. Ct. 1493 (2022), in which the Supreme Court held that the 30-day deadline for Collection Due Process (CDP) hearings under section 6330(d)(1) is jurisdictional and not subject to equitable tolling. The IRS contended that the same reasoning should apply to section 6234(a), given the BBA’s emphasis on finality in partnership audits. On the merits, the IRS asserted that the FPA was properly mailed to the partnership’s last known address—“100 Bull Street, Ste 212”—as reflected in the 2020 Form 1065 and the NOPPA issued in May 2024. It dismissed Kings Road’s due diligence claim, arguing that the partnership failed to demonstrate prejudice from the alleged mailing error, particularly since Kings Road filed a protective petition on July 9, 2025, well before the FPA was actually mailed. Finally, the IRS rejected the VRA challenge, asserting that the TSPC who signed the FPA was acting within the scope of her delegated authority under IRS Delegation Order 150-10, which authorizes LB&I officials to issue FPAs under the BBA partnership audit regime.

The clash over equitable estoppel further underscored the divide. Kings Road invoked the doctrine to argue that the IRS should be estopped from enforcing the 90-day deadline due to its misrepresentations—specifically, the agent’s statement in May 2025 that “there had been no activity on the Kings Road account” since August 2024. The IRS countered that equitable estoppel does not apply against the government, citing longstanding precedent that the doctrine is generally unavailable in tax cases absent extraordinary circumstances. It argued that Kings Road’s reliance on the agent’s statement was misplaced, as the IRS had no obligation to affirmatively confirm the correctness of the address before mailing the FPA. The agency also emphasized that Kings Road’s failure to receive the FPA did not excuse its untimely petition, as the mailbox rule under Goldston v. Commissioner, 156 T.C. No. 8 (2021), creates a presumption of delivery for certified mail, even if unclaimed.

At its core, the dispute distilled into a battle over who bears the burden when the IRS’s administrative machinery fails. Kings Road framed the case as one of extraordinary circumstances—the IRS’s reliance on an outdated address, its failure to update records despite clear notice of new counsel, and its misinformation to Kings Road’s counsel—that prevented the partnership from knowing an FPA had even been issued. The IRS, however, insisted that the BBA’s centralized audit regime demands strict adherence to deadlines, and that any deviation would undermine the finality Congress intended. The Tax Court’s resolution of this tension would determine whether the IRS’s procedural errors could override the rigid timelines governing partnership audits—or whether taxpayers must bear the cost of the agency’s mistakes.

The Court's Reckoning: Why the BBA's Deadlines Are Different from TEFRA's

The Tax Court’s resolution of this dispute in Kings Road Partners, LLC v. Commissioner (T.C. Memo. 2026-121, Judge Lauber, filed 9/15/2026) did not merely resolve a procedural skirmish—it redefined the balance of power between the IRS and taxpayers under the Bipartisan Budget Act of 2015 (BBA). The court’s holding that the 90-day petition deadline in § 6234(a) is subject to equitable tolling—unlike the jurisdictional deadlines under the repealed TEFRA regime—marks a decisive shift in how partnership audits will be litigated. The opinion, issued just weeks after Big Apple Tompkins Realty LLC v. Commissioner (T.C. Memo. 2026-5, 8/5/2026), where the court first held that § 6234(a) is not jurisdictional, now squarely addresses whether equitable tolling applies. The answer: it does, and the IRS’s procedural missteps in this case could not override it.

The court’s reasoning hinged on a fundamental distinction between the BBA’s streamlined partnership audit regime and the labyrinthine TEFRA framework it replaced. Under TEFRA, the petition deadline in § 6226(a) was treated as jurisdictional, a conclusion the Tax Court reaffirmed in North Wall Holdings, LLC v. Commissioner (165 T.C. 143, 2025). The court in North Wall emphasized that TEFRA’s deadlines were embedded in a "highly technical" system where multiple layers of deadlines—some for the tax matters partner (TMP), others for notice partners—created a rigid structure Congress intended to enforce strictly. The court warned that allowing equitable tolling in TEFRA cases would "wreak havoc" on the assessment process, which required partner-by-partner computations and layered notices of deficiency. As the court noted, "Even setting aside the question of jurisdiction, the complexity of the TEFRA provisions leaves no room for equitable tolling of the petition deadlines in section 6226." The BBA, by contrast, eliminated this complexity. The court observed that § 6234(a) "does not contain the same technical wording or explicit exceptions as its predecessor TEFRA equivalent," and its simplicity—replacing TEFRA’s multi-tiered deadlines with a single 90-day window—signaled Congress’s intent to allow flexibility where TEFRA had none.

This distinction was not merely academic. The court explicitly rejected the IRS’s argument that the BBA’s deadlines should be treated like TEFRA’s, finding that the "administrative and practical burdens that led us to rebut the presumption in favor of equitable tolling for section 6226 (TEFRA) are simply not present for the BBA." The court’s analysis turned on the text and structure of § 6234(a), which it described as a "straightforward" deadline with no "interplay of that deadline with related provisions of the Code" that would suggest Congress intended to preclude tolling. The court cited Enbridge Energy, LP v. Nessel ex rel. Michigan (146 S. Ct. 1074, 2026), where the Supreme Court emphasized that statutory deadlines must be interpreted in light of their text and structure, and found that § 6234(a)’s plain language did not rebut the presumption of equitable tolling established in Holland v. Florida (560 U.S. 631, 2010) and Boechler, P.C. v. Commissioner (142 S. Ct. 1493, 2022). The court held: "Nothing in the text or structure of section 6234(a) or its related provisions rebuts the presumption in favor of equitable tolling. Thus, the 90-day deadline in section 6234(a) is subject to equitable tolling."

The court then applied the two-part test for equitable tolling: whether Kings Road "pursued its rights diligently" and whether "extraordinary circumstances outside of its control prevented it from filing on time." The court found both elements satisfied. On diligence, the court credited Kings Road’s efforts to track the FPA’s issuance, including follow-ups with counsel, obtaining IRS transcripts, and contacting the IRS to inquire about the FPA’s status. The court distinguished this from cases where taxpayers merely "watched the mailbox," noting that Kings Road’s counsel "did more than merely watch the mailbox" by actively investigating whether an FPA had been issued. The court also emphasized that Kings Road filed a protective petition based on a "reasonably calculated deadline," unaware that the IRS had mailed the FPA nearly a month earlier than its deadline for doing so. On extraordinary circumstances, the court found that the IRS’s misinformation—telling Kings Road counsel that no FPA had been mailed when it had been—combined with the returned mail, created circumstances beyond Kings Road’s control. The court cited Jackson v. Astrue (506 F.3d 1349, 2007), where the Eleventh Circuit recognized that misinformation from a government agency can constitute an extraordinary circumstance, even without deliberate concealment.

The court also rejected Kings Road’s argument that the FPA was invalid due to a minor address abbreviation—"STE 212" instead of "Suite 212"—finding that the error did not prevent delivery and was not prejudicial. The court applied the standard from Wilson v. Commissioner (T.C. Memo. 1997-515), which held that minor address errors do not invalidate a notice if they would not have prevented delivery or caused prejudice. The court distinguished Wilson, where transposed numbers in an address invalidated the notice, from this case, where the abbreviation "Ste" for "Suite" was a "commonly recognized abbreviation" that did not affect delivery. The court noted that Kings Road received a Notice of Proposed Partnership Adjustment (NOPPA) addressed to the same abbreviated address, confirming that the error was inconsequential. The court also held that the IRS met its burden of proving proper mailing under § 6231(a), which requires mailing to the partnership’s last known address, even if the USPS Form 3877 was technically defective. The court found that the IRS’s additional evidence—including tracking records, internal transcripts, and a declaration from the Taxpayer Services Processing Center—sufficed to establish proper mailing.

Finally, the court addressed Kings Road’s argument that the IRS failed to exercise due diligence and that equitable estoppel applied. The court rejected both, finding no evidence of affirmative misconduct by the IRS and no prejudice to the IRS from tolling the deadline. The court noted that the IRS’s misinformation—telling Kings Road counsel that no FPA had been mailed—did not constitute affirmative misconduct, and that the IRS had acted diligently in attempting to mail the FPA. The court also rejected Kings Road’s argument that the IRS lacked authority to issue the FPA due to a violation of the Federal Vacancies Reform Act (VRA), finding that the acting IRS Commissioner had authority under 5 U.S.C. § 3345(a)(2) and § 3345(a)(3) as the first assistant and deputy commissioner.

The court’s holding has immediate and far-reaching implications. For partnerships, it signals a new era of flexibility in BBA audits, where procedural errors by the IRS—such as mailing to an incorrect address or providing misinformation—may toll otherwise rigid deadlines. The court’s distinction between the BBA’s streamlined regime and TEFRA’s complex framework underscores that the BBA was intended to simplify partnership audits, not to replicate TEFRA’s rigid procedural strictures. The opinion also reinforces the Supreme Court’s guidance in Boechler that nonjurisdictional deadlines are presumptively subject to equitable tolling, a principle that will shape future litigation over BBA deadlines. For the IRS, the decision serves as a cautionary tale: its procedural missteps in this case nearly cost it the ability to enforce the 90-day deadline, and future partnerships will undoubtedly cite Kings Road to challenge untimely notices or misinformation from the agency. The Tax Court’s exercise of its judicial power here was not merely declaratory—it was a deliberate reassertion of its role as a check on IRS procedural overreach in the BBA era.

The Push-Out Problem: Did Kings Road Miss Its Chance to Shift the Burden?

The Tax Court’s refusal to address whether the 45-day push-out election deadline under § 6226(a) can be equitably tolled leaves a critical procedural gap in BBA partnership audits—a gap that future partnerships may exploit to challenge IRS timeliness errors. The court’s silence on this issue underscores a broader tension: while partnerships grapple with the IRS’s procedural missteps, the Tax Court has yet to clarify whether equitable tolling applies to the push-out election’s strict statutory deadline. This unresolved question could redefine how partnerships respond to untimely FPAs, particularly when the IRS’s own failures create confusion.

Kings Road’s argument hinged on prejudice: it claimed it was unable to make a push-out election because it never received the Final Partnership Adjustment (FPA) and was misled by the IRS when its representative inquired about the notice. The partnership contended that the IRS’s failure to properly mail the FPA—either by sending it to an incorrect address or failing to confirm delivery—should toll the 45-day deadline. Yet the court found Kings Road’s position unsupported by evidence. The opinion noted that Kings Road did not provide any proof it attempted to make a push-out election or even filed a protective push-out election, which would have preserved its rights while the dispute over the FPA’s validity played out. Without such evidence, the court could not determine whether the partnership suffered actual prejudice from the IRS’s alleged procedural errors.

The court’s analysis hinged on the plain language of § 6226(a), which states that a push-out election must be made "not later than 45 days after the date of the FPA." The statute contains no explicit provision for equitable tolling, and the Tax Court has historically been reluctant to imply such relief absent clear congressional intent. In Boechler, P.C. v. Commissioner, the Supreme Court held that § 6330(d)(1)’s 30-day deadline for Collection Due Process (CDP) hearings is jurisdictional and not subject to equitable tolling, reinforcing the principle that statutory deadlines in tax procedure are strictly enforced unless Congress has provided otherwise. While § 6226(a) is not explicitly labeled jurisdictional, its mandatory 45-day window suggests a similar rigidity. The Tax Court’s decision not to address equitable tolling in Kings Road may signal a preference for deferring this question until a case presents a stronger factual record—one where the taxpayer has affirmatively attempted to comply with the statute despite IRS errors.

Kings Road’s failure to file a protective push-out election proved fatal to its argument. A protective election—filed within the 45-day window while disputing the FPA’s validity—would have allowed the partnership to preserve its rights without waiving its challenge to the IRS’s procedural missteps. The court emphasized that Kings Road did not explain why it could not have filed such an election, leaving the IRS with no basis to toll the deadline. This omission is particularly striking given that the partnership had already filed a protective petition challenging the FPA’s timeliness, demonstrating familiarity with procedural safeguards. The court’s pointed observation that Kings Road failed to address whether the deadline could be tolled suggests that future partnerships must proactively mitigate IRS errors by using protective elections—a strategy that could become standard practice in BBA audits.

The implications for partnerships are stark. The IRS’s procedural missteps in this case—failing to mail the FPA or confirm delivery—did not absolve Kings Road of its obligation to act within the 45-day window. For partnerships facing similar issues, the lesson is clear: rely on protective elections, not equitable tolling, to preserve rights when the IRS’s timeliness is in doubt. The Tax Court’s refusal to entertain tolling arguments in Kings Road may embolden the IRS to argue that § 6226(a)’s deadline is absolute, forcing partnerships to adopt a more defensive posture in audit proceedings. Whether the court will revisit this issue in a future case remains an open question, but for now, partnerships must treat the 45-day push-out election deadline as non-negotiable—even when the IRS drops the ball.

What This Means for Partnerships: A New Era of Flexibility in BBA Audits?

The Tax Court’s ruling in Kings Road Property, LLC marks a decisive shift in how partnership audit deadlines under the Bipartisan Budget Act of 2015 (BBA) are treated, signaling a departure from the rigid jurisdictional deadlines of the TEFRA era. For partnerships navigating the BBA regime, the court’s decision introduces a level of flexibility that was previously unthinkable under TEFRA’s strict time constraints. The implications are immediate and far-reaching, particularly for partnerships that rely on precise tracking of IRS communications and deadlines.

The court’s holding that § 6234(a)’s 90-day petition deadline is not jurisdictional—and may be equitably tolled—creates a safety net for partnerships that fall victim to IRS missteps, such as misdelivered notices or misinformation from agents. This is a stark contrast to TEFRA’s § 6226(a) deadline, which the Tax Court in North Wall Holdings, LLC explicitly deemed jurisdictional, leaving no room for equitable tolling. The distinction is critical: under TEFRA, a missed deadline was a death knell, but under BBA, partnerships now have a pathway to preserve their rights when the IRS fails to act diligently. The court’s reliance on Big Apple Tompkins Realty LLC (167 T.C. No. 5, Aug. 5, 2026) to support this shift underscores the newfound judicial willingness to apply equitable principles to BBA deadlines, a development that could reshape how partnerships approach audit timelines.

For practitioners, the ruling demands a proactive stance. Partnerships must now diligent track the issuance of Notices of Proposed Partnership Adjustments (NOPPAs) and Final Partnership Adjustments (FPAs), but they also have recourse if the IRS drops the ball. The court’s explicit endorsement of equitable tolling—where the burden falls on the partnership to prove diligence and extraordinary circumstances—means that partnerships should document every interaction with the IRS, from phone calls to address updates. The IRS’s misinformation in Kings Road—where an agent falsely assured counsel that no FPA had been mailed—was deemed an extraordinary circumstance sufficient to toll the deadline. This sets a precedent: IRS errors, whether in mailing, address records, or agent statements, can now serve as the basis for tolling arguments, provided the partnership can demonstrate it pursued its rights diligently.

The court’s rejection of Kings Road’s minor address error argument—where the FPA was mailed to “Ste 212” instead of “Suite 212”—further clarifies that minor clerical errors in notices do not invalidate the FPA if the NOPPA was delivered. This is a pragmatic resolution that aligns with the IRS’s statutory duty to mail notices to the partnership’s last known address under § 6231(a)(7). The IRS’s failure to update its records with the partnership’s new counsel’s address, despite the Form 2848 being on file, did not prejudice Kings Road because the NOPPA was successfully delivered. The court’s holding that “the application of equitable tolling mitigated any prejudice” suggests that even if a notice is technically defective, the partnership’s diligence in pursuing its rights can cure the defect. This is a critical takeaway for practitioners: while minor errors may not invalidate a notice, partnerships should still proactively verify that the IRS has the correct address and document any changes to avoid unnecessary disputes.

The court’s dismissal of Kings Road’s Federal Vacancies Reform Act (VRA) challenge to the acting Commissioner’s authority to sign the FPA is equally consequential. The partnership argued that the FPA was invalid because it was signed by an acting Commissioner who lacked VRA-approved authority. The court swiftly rejected this argument, emphasizing that VRA challenges to IRS officials’ authority are unlikely to succeed unless the appointment violates the 210-day statutory limit or other clear statutory constraints. This reinforces the IRS’s broad delegated authority under Delegation Order 150-10, which empowers LB&I officials to issue FPAs. For partnerships, this means that VRA-based challenges to IRS actions are a high-risk, low-reward strategy, and practitioners should focus instead on procedural defenses like equitable tolling or mailing errors.

The ruling also introduces a new layer of complexity for partnerships considering push-out elections under § 6226. The court’s refusal to entertain Kings Road’s argument that the 45-day push-out election deadline is jurisdictional—despite the IRS’s own motion to dismiss—suggests that § 6226’s deadline may also be subject to equitable tolling. While the court did not explicitly rule on this issue, its willingness to apply tolling principles to § 6234(a) leaves the door open for future challenges. Practitioners should therefore file protective petitions and push-out elections within the strict deadlines, but also be prepared to argue for tolling if the IRS’s timeliness is in doubt. The Tax Court’s refusal to entertain tolling arguments in Kings Road may embolden the IRS to argue that § 6226’s deadline is absolute, but the court’s broader equitable framework suggests that partnerships have a fighting chance if they can demonstrate IRS misconduct.

The practical takeaway for partnerships is clear: the BBA regime is no longer a minefield of rigid deadlines and jurisdictional traps. Instead, it offers a new era of flexibility, where partnerships can challenge IRS errors and preserve their rights through equitable tolling. The court’s ruling in Kings Road is a judicial acknowledgment that the IRS’s administrative failures should not automatically doom partnerships to forfeit their day in court. For practitioners, this means adopting a more assertive and documented approach to audit communications, from tracking NOPPA and FPA deadlines to verifying address changes and agent statements. The era of passive reliance on IRS procedures is over; partnerships must now actively monitor and challenge IRS actions to protect their interests. The Tax Court has signaled its willingness to intervene when the IRS falls short, and partnerships would be wise to heed that warning.
