Accuracy-Related Partnership Penalties Under § 6662 Are “Taxes” for AIA/DJA Jurisdiction-Stripping Purposes

I. Introduction

Norcave Properties sits at the intersection of (i) the modern partnership audit regime created by the Bipartisan Budget Act of 2015 (the “BBA”), (ii) the Internal Revenue Code’s treatment of “penalties” as part of “tax” for enforcement and collection, and (iii) the jurisdiction-stripping force of the Anti-Injunction Act (“AIA”) and the Declaratory Judgment Act (“DJA”) in federal tax controversies.

Norcave Properties, L.L.C. (“Norcave”), a partnership, claimed a charitable deduction after donating a conservation servitude on 321.13 acres (2018). After audit, the IRS issued a Notice of Final Partnership Adjustment (“FPA”) in 2025 disallowing the deduction and asserting penalties—originally including a civil fraud penalty (26 U.S.C. § 6663) and accuracy-related valuation/negligence-type penalties (26 U.S.C. § 6662). Norcave sued in federal district court seeking pre-payment declaratory and injunctive relief and demanded a jury trial, framing the dispute as a Seventh Amendment entitlement to contest tax penalties before paying them.

While the appeal was pending, the IRS abandoned the civil fraud penalty, leaving only the § 6662 accuracy-related penalties at issue. The central question became jurisdictional: are those penalties “tax” such that a pre-payment suit “for the purpose of restraining the assessment or collection” is barred by the AIA, and likewise blocked by the DJA’s federal tax exception?

II. Summary of the Opinion

The Fifth Circuit affirmed dismissal for lack of subject matter jurisdiction. It held:

• Accuracy-related penalties under 26 U.S.C. § 6662 “merge into” tax liability for purposes of the AIA and DJA because 26 U.S.C. § 6665(a)(2) deems references to “tax” in Title 26 to include Chapter 68 penalties.
• Under the Supreme Court’s “objective aim” framework from CIC Services, LLC v. IRS, the court looks to the relief requested on the face of the complaint. Norcave’s requested declaratory/injunctive relief would obstruct an assessment already in motion (the FPA and its asserted penalties), triggering the AIA.
• Norcave had alternative paths for contesting the adjustments/penalties consistent with Congress’s tax-litigation design—particularly via the Tax Court, which can entertain pre-payment challenges in the partnership-FPA context.

Because jurisdiction was absent, the Fifth Circuit did not reach the merits of Norcave’s Seventh Amendment theory; it simply held the suit could not proceed in district court as a pre-payment challenge.

III. Analysis

A. Precedents Cited and Their Influence

1. Defining the tax-administration baseline: pay-now-sue-later

• NFIB v. Sebelius, 567 U.S. 519 (2012): The opinion uses NFIB v. Sebelius for two related points. First, it reiterates the AIA’s function of protecting the government’s “consistent stream of revenue” by barring suits that would obstruct tax collection. Second, it leverages NFIB’s observation that Congress may label an exaction a “penalty” yet “direct that it nonetheless be treated as a tax” for AIA purposes, especially where the Code includes deeming provisions (the district court quoted NFIB’s discussion of § 6671(a)). The Fifth Circuit then analogizes that logic to § 6665 for Chapter 68 accuracy-related penalties.
• Holland v. Westmoreland Coal Co. (In re Westmoreland Coal Co.), 968 F.3d 526 (5th Cir. 2020): Quoted for the policy premise (drawn from NFIB) that Congress requires tax disputes to be litigated “only after they are paid,” reflecting the system’s structural preference for refund suits and Tax Court channels rather than pre-assessment injunctions.

2. “Assessment,” “collection,” and what it means to “restrain”

• Direct Mktg. Ass'n v. Brohl, 575 U.S. 1 (2015): The court uses Direct Marketing to anchor the meaning of “assessment” and “collection” as tax terms of art, and to show that “restrain” does not cover suits that merely “inhibit” tax functions incidentally—while also recognizing that the AIA/TIA generally block suits aimed at core assessment/collection steps. The opinion also leans on Direct Marketing to support cross-statute interpretation: because the Tax Injunction Act (“TIA”) was modeled on the AIA, similar words are presumed to carry similar meaning.
• Hibbs v. Winn, 542 U.S. 88 (2004): Cited within the discussion of AIA/TIA relationship, reinforcing that the Supreme Court treats the statutes as close analogues in interpretive method.

3. The “objective aim” test for AIA applicability

• CIC Services, LLC v. IRS, 593 U.S. 209 (2021): This is the opinion’s principal doctrinal engine. The court adopts CIC Services’s instruction to assess not subjective motive but the suit’s “objective aim,” i.e., the relief requested. CIC Services held that a pre-enforcement challenge to a reporting requirement did not trigger the AIA because the reporting rule and the tax penalty were “several steps removed,” and criminal penalties helped show the suit targeted a “standalone” regulatory mandate rather than tax assessment/collection itself. The Fifth Circuit distinguishes Norcave’s case: § 6662 penalties are not “standalone” reporting mandates but are treated as part of the “tax” via § 6665, and Norcave sought to stop an assessment already underway.
• Bob Jones Univ. v. Simon, 416 U.S. 725 (1974) and Alexander v. "Americans United" Inc., 416 U.S. 752 (1974): Cited through CIC Services for the proposition that courts look to the complaint’s face and the “thing sought to be enjoined,” and for the AIA’s purpose: minimizing pre-enforcement judicial interference with assessment and collection.

4. Fifth Circuit’s own application of CIC Services in tax-injunction settings

• Harward v. City of Austin, 84 F.4th 319 (5th Cir. 2023) (per curiam): This is the opinion’s key intra-circuit analogue. Harward permitted challenges to a preliminary geographic-identification step (a prerequisite), but barred remedies that would negate notices and assessment activity already in motion. The Fifth Circuit uses Harward to reinforce that under the objective-aim test, once assessment machinery is engaged, injunctions/declarations aimed at stopping it are barred. The court treats the FPA similarly: Norcave’s requested relief is directed at the asserted penalties embedded within the assessment process.

5. Penalties treated as “tax” for AIA purposes

• Warren v. United States, 874 F.2d 280 (5th Cir. 1989): Used to establish circuit precedent that the AIA’s reference to “tax” is “deemed also to refer to certain penalties,” supporting the move that Chapter 68 penalties—when the Code says so—fall within the AIA’s “tax” umbrella.

6. Alternative-remedy and narrow exception doctrine

• South Carolina v. Regan, 465 U.S. 367 (1984): The opinion acknowledges South Carolina’s narrow “no alternative remedy” concept, but finds it inapplicable because Norcave has an alternative forum: the Tax Court route for FPAs.
• RYO Mach., LLC v. U.S. Dep't of Treasury, 696 F.3d 467 (6th Cir. 2012) and Judicial Watch v. Rossotti, 317 F.3d 401 (4th Cir. 2003): Cited to emphasize that the South Carolina exception is construed “very narrowly,” underscoring the Fifth Circuit’s reluctance to create “escape valves” around the AIA’s jurisdictional command.

7. DJA breadth relative to AIA

• Rivero v. Fid. Invs. Inc., 1 F.4th 340 (5th Cir. 2021): Cited for the proposition that the DJA’s federal tax exception is “at least as broad” as the AIA—supporting the court’s conclusion that even if the AIA analysis were debated, the DJA would independently foreclose declaratory jurisdiction.

8. Partnership regime context and centralized audits

• United States v. Woods, 571 U.S. 31 (2013): Used for the historical problem Congress sought to solve—duplicative, inconsistent partner-level proceedings—thereby justifying entity-level adjustments. This context helps explain why Congress channelled FPA disputes into specific forums and procedures, limiting district court pre-payment intervention.
• Moore v. United States, 602 U.S. 572 (2024): Cited for the general concept that Congress sometimes treats entities as pass-throughs, illustrating how partnership income and related items ultimately tax partners.
• Baxter v. United States, 48 F.4th 358 (5th Cir. 2022): Mentioned in the procedural background (not for a central holding in this opinion) to note the post-BBA centralized regime for partnership items.

9. The court’s “you have a forum” response to the Seventh Amendment framing

• Silver Moss, 165 T.C. No. 3: The opinion cites this Tax Court conservation-easement case to show that the Tax Court has already entertained similar disputes (including constitutional arguments), reinforcing that Norcave’s claimed lack of forum is incorrect as a jurisdictional matter.
• Cheek v. United States, 498 U.S. 192 (1991): Cited to contrast civil penalties with criminal tax prosecutions. The Fifth Circuit notes that criminal tax matters (prosecuted by DOJ) carry jury trial rights, but Norcave’s civil accuracy-related penalties do not force any “violate-the-law-first” dilemma of the kind that concerned the Court in CIC Services.

B. Legal Reasoning

1. The suit’s “objective aim” was to stop a tax assessment already underway

The Fifth Circuit frames the inquiry exactly as CIC Services instructs: look to the relief requested and identify the suit’s objective aim. Norcave requested declaratory and injunctive relief that would prevent the IRS from pursuing and imposing the asserted § 6662 penalties, and it demanded a pre-payment jury trial to adjudicate them. That configuration is, functionally, a bid to interrupt assessment/collection of an asserted liability.

The court rejects Norcave’s attempt to re-describe its suit as targeting a “separate legal mandate” (the Seventh Amendment) rather than the tax itself. Under CIC Services, the question is not the plaintiff’s characterization but what the injunction/declaration would do. Here it would obstruct the IRS’s ongoing penalty assertion embedded in the FPA process.

2. Chapter 68 accuracy-related penalties are “tax” under Title 26 for AIA purposes

The doctrinal pivot is 26 U.S.C. § 6665, especially § 6665(a)(2), which provides that “any reference in this title to ‘tax’ imposed by this title shall be deemed also to refer to the additions to the tax, additional amounts, and penalties provided by this chapter.” The court treats this as a clear congressional instruction: for Title 26—including the AIA housed in Title 26—accuracy-related penalties are treated as “tax.”

This move does more than “interpret” the AIA; it applies an express definitional/coordination rule embedded in the Code. The Fifth Circuit also notes that it has previously recognized this structure (Warren v. United States), and the Supreme Court has recognized Congress’s power to treat penalties as taxes for AIA purposes (NFIB v. Sebelius).

3. Why CIC Services does not open the door here

Norcave’s principal hope was to analogize itself to CIC Services, where a reporting mandate with a tax penalty did not trigger the AIA. The Fifth Circuit distinguishes CIC Services on two grounds grounded in the opinion’s text:

• Attenuation vs. integration: In CIC Services, the reporting rule and tax penalty were “several steps removed,” and the suit “aim[ed] to enjoin a standalone reporting requirement.” Here, by contrast, § 6662 penalties are integrated into tax liability by § 6665.
• Criminal overlay: CIC Services emphasized criminal penalties as “clinching” the conclusion that the suit targeted more than a tax assessment. Norcave’s dispute involves civil penalties; no pathway requires violating criminal law to obtain review.

4. Congressional forum design defeats the “no forum” narrative

The Seventh Amendment argument was presented as a need for pre-payment district court adjudication. The Fifth Circuit answers in jurisdictional terms: Congress has designed specific channels for contesting partnership FPAs and related penalties. The opinion highlights:

• Tax Court path: Under 26 U.S.C. § 6234 and § 6234(b)(1), a partnership can pursue pre-payment review in Tax Court.
• District court/CFC path: If a partnership chooses district court or the Court of Federal Claims, it generally must deposit the imputed underpayment and penalties.
• Bench-trial structure: Congress generally mandates bench trials in tax refund litigation via 28 U.S.C. § 2402, with a noted jury-trial carveout for certain suits under 28 U.S.C. § 1346(a)(1). The opinion treats partnership adjustment disputes as channeled to bench adjudication.
• Partner-level pathways: The court notes that because partnership tax items can “pass through,” partners may have individual access to forums if the partnership uses the push-out election (26 U.S.C. § 6226).

In short, the court denies that the AIA should be relaxed to accommodate a jury-trial demand, particularly where Congress has provided alternative routes to litigate the penalty.

C. Impact

1. Closing a jurisdictional workaround for § 6662 penalties in partnership cases

The opinion’s practical rule is straightforward: a partnership (or similarly situated taxpayer) cannot repackage a challenge to asserted § 6662 accuracy-related penalties as a constitutional/jury-trial claim and thereby obtain pre-payment injunctive or declaratory relief in federal district court. If the relief would stop the IRS from assessing/collecting the penalty, the AIA and DJA foreclose jurisdiction.

2. Reinforcing the “objective aim” test within the Fifth Circuit

Building on CIC Services and Harward v. City of Austin, the Fifth Circuit reinforces a functional inquiry: once assessment activity is “already in motion” (here, by FPA and asserted penalties), attempts to nullify or pause it via injunction/declaration are barred. This is likely to influence pleading strategies in the circuit; artful constitutional labeling will not control if the requested relief functionally restrains tax enforcement.

3. Confirming the breadth of “tax” via § 6665’s deeming rule

The court’s reliance on § 6665(a)(2) is consequential beyond conservation-easement cases. The same coordination logic can apply to other Chapter 68 penalties when plaintiffs attempt to file pre-payment challenges in district court. The decision thus strengthens the government’s jurisdictional defenses when penalties are statutorily deemed part of “tax.”

4. Particular relevance to conservation-easement audit disputes

Although the holding is not limited to conservation servitudes, the factual backdrop (charitable deduction disallowance and valuation-related penalties) tracks a high-volume area of enforcement. By pointing to Tax Court practice (Silver Moss), the opinion nudges these disputes toward established tax fora rather than constitutional collateral attacks in district court.

IV. Complex Concepts Simplified

V. Conclusion

Norcave Properties establishes (and within the Fifth Circuit, cements) a jurisdictional rule with significant bite: when Congress has deemed Chapter 68 accuracy-related penalties to be “tax” through 26 U.S.C. § 6665, a pre-payment district court suit seeking declaratory or injunctive relief against those penalties is barred by both the AIA and the DJA’s federal tax exception.

The opinion’s broader significance is methodological. It reaffirms that AIA analysis turns on function over form—especially through CIC Services’s objective-aim framework— and it emphasizes Congress’s deliberate channeling of partnership tax controversies into specialized, largely non-jury fora. As a result, litigants cannot obtain a pre-payment, jury-triable district-court forum simply by reframing an assessment dispute as a constitutional attack on the procedural structure Congress selected.
