§ 4261 “Ticket Tax” Covers Flight-by-Flight Usage Charges, Not Fixed Fractional-Jet Management Fees (and Requires “Precise and Not Speculative” Notice to Third-Party Collectors)

Case: Flight Options, LLC v. United States (6th Cir. May 27, 2026)
Court: United States Court of Appeals for the Sixth Circuit
Panel: Sutton, C.J.; Clay and Murphy, JJ. (Murphy, J., concurring)
Core Holding: The § 4261 excise tax on “amount paid for” “transportation by air” applies to flight-specific usage charges, not fixed membership/management/overhead fees; and the IRS cannot impose collector liability absent “precise and not speculative” guidance.

I. Introduction

This appeal arose from a $39 million assessment (tax, interest, and penalties) against Flight Options, a fractional-share private jet company, for allegedly failing to collect the 7.5% federal air transportation excise tax under 26 U.S.C. §§ 4261–4262 on fixed monthly management fees and membership fees it charged customers. Flight Options collected and remitted the tax on flight-by-flight “usage fees” (e.g., hourly flight charges, repositioning, waiting time tied to specific trips), but it treated fixed fees as payments for ownership-program administration and fleet overhead rather than “amount[s] paid for” “transportation by air.”

The government’s position reflected an IRS enforcement shift (not embodied in a regulation or revenue ruling targeted to fractional-jet programs) that began with a 2004 technical advice memo to Bombardier and later audits. The district court agreed with the IRS and imposed penalties; the Sixth Circuit reversed, concluding that the “ticket tax” does not reach fixed fees and, in any event, the IRS failed to provide the kind of clear prospective notice demanded when private parties are conscripted as tax collectors.

II. Summary of the Opinion

Chief Judge Sutton’s opinion reverses the judgment for the government. The court holds:

  • Text and structure: The § 4261 levy—expressly labeled a “ticket tax” during the relevant period—targets payments for discrete air travel (moving persons from point A to point B), i.e., flight-by-flight usage charges, not fixed fees for program overhead and management.
  • Regulatory context: Treasury regulations treat various flight-adjacent charges (e.g., “parking,” “[de]icing,” “sanitation,” “dockage,” “wharfage,” and “similar charges”) as non-taxable if separable, underscoring that the tax is not an all-costs “but for transportation” levy.
  • Taxpayer/withholder canons: The court applies the long-recognized principle against expanding tax statutes beyond “clear import” and relies heavily on Central Illinois Pub. Serv. Co. v. United States, requiring “precise and not speculative” notice before imposing third-party collection liability.
  • Administrative guidance rejected as binding: IRS technical advice memoranda and an “Audit Technique Guide” cannot supply binding notice to other taxpayers, and revenue rulings’ “reasonably necessary” gloss lacked persuasive force and workable limiting principles.

Judge Murphy concurred, agreeing with the result and adding an extended discussion highlighting tension in Supreme Court precedent over competing interpretive canons in tax cases (pro-taxpayer vs. “legislative grace” approaches), while emphasizing that canons operate as tie-breakers after the best reading is determined.

III. Analysis

A. Precedents Cited

The opinion is unusually precedent-dense, using prior decisions less to resolve a narrow factual dispute than to police the boundary between (1) statutory text and binding regulations and (2) informal IRS positions that attempted to expand the excise tax base.

  • Rock Island, Ark. & La. R.R. Co. v. United States, 254 U.S. 141 (1920): Invoked for the maxim that taxpayers must “turn square corners.” The Sixth Circuit uses the phrase to frame a key theme: a system demanding precision from taxpayers must also provide “seen corners,” not “unseen ones,” when imposing collection duties.
  • Summa Holdings, Inc. v. Comm'r, 848 F.3d 779 (6th Cir. 2017): Quoted for the ideal that the Code should be “accessible” to those with “time and patience.” The court uses it to criticize the government’s attempt to apply an indeterminate “reasonably necessary” standard to complex fixed-fee structures.
  • Exec. Jet Aviation, Inc. v. United States, 125 F.3d 1463 (Fed. Cir. 1997): A central industry backdrop. It upheld applying the excise tax to fractional-jet “usage fees,” while acknowledging that the IRS had not applied the tax to fixed monthly fees. The Sixth Circuit treats Exec. Jet as confirming the flight-specific nature of “transportation” and as reinforcing the absence of historical notice for taxing fixed fees.
  • Bombardier Aerospace Corp. v. United States, 831 F.3d 268 (5th Cir. 2016): Used both for factual context (IRS’s 2004 shift; industry audits) and doctrinal support: it exemplifies courts scrutinizing whether any binding “regulation or ruling require[d] withholding” and illustrates why a technical advice memorandum binds only its recipient.
  • NetJets Large Aircraft Inc. v. United States, 2015 WL 7784925 (S.D. Ohio Nov. 12, 2015) (and NetJets Large Aircraft, Inc. v. United States, 80 F. Supp. 3d 743 (S.D. Ohio 2015)): Cited for the proposition that the IRS failed to supply “precise and not speculative” guidance regarding monthly management fees and for the observation that no revenue ruling directly addressed fractional-jet programs’ fixed fees.
  • Gould v. Gould, 245 U.S. 151 (1917) (plus Am. Net & Twine Co. v. Worthington, 141 U.S. 468 (1891)): The opinion relies on these as classic statements of the anti-expansion principle in tax law—no tax by implication; no enlargement beyond “clear import.” This canon supports the court’s narrow reading of “for transportation.”
  • Central Illinois Pub. Serv. Co. v. United States, 435 U.S. 21 (1978): The doctrinal fulcrum. The Sixth Circuit reads it to bar imposing third-party collection obligations unless statutes/regulations/judicial authority give “precise and not speculative” notice. The court uses Central Illinois to reject the IRS’s retroactive imposition of liability on Flight Options for fixed fees and to emphasize the severe asymmetry of risks (undercollection liability, overcollection exposure, personal liability for officers).
  • OfficeMax, Inc. v. United States, 428 F.3d 583 (6th Cir. 2005): Quoted for the “put his finger on the law” formulation and used to limit deference to thinly reasoned administrative guidance.
  • Christensen v. Harris County, 529 U.S. 576 (2000) and Skidmore v. Swift & Co., 323 U.S. 134 (1944): The court declines “Skidmore respect” for revenue rulings that lack persuasive reasoning and a limiting principle.
  • Burrage v. United States, 571 U.S. 204 (2014): Cited for the commonsense point that governmental uncertainty about a test’s application signals citizen uncertainty too—supporting the conclusion that notice was inadequate.
  • Grayned v. City of Rockford, 408 U.S. 104 (1972): Used to analogize the IRS’s indeterminate standard to “ad hoc and subjective” enforcement, highlighting arbitrariness concerns.
  • W. Rsrv. Acad. v. United States, 801 F.2d 250 (6th Cir. 1986) (adopting 619 F. Supp. 394 (N.D. Ohio 1985)), Univ. of Chi. v. United States, 547 F.3d 773 (7th Cir. 2008), HB & R, Inc. v. United States, 229 F.3d 688 (8th Cir. 2000), Am. Airlines, Inc. v. United States, 204 F.3d 1103 (Fed. Cir. 2000), and Gen. Elevator Corp. v. United States, 20 Cl. Ct. 345 (1990): The opinion cites this multi-circuit line to show that courts have consistently required clear, prospective guidance before enforcing third-party withholding/collection duties.
  • Shell Oil v. United States, 221 Ct. Cl. 296 (1979): The government leaned on this “waiting time” case; the Sixth Circuit distinguishes it as involving waiting time for specific on-demand flights, not general program overhead.

B. Legal Reasoning

1. Textual anchor: “ticket tax” and “for transportation by air”

The opinion’s first move is definitional and structural: § 4261 was, at relevant times, expressly framed as a “ticket tax.” Against that label, the court reads “amount paid for taxable transportation” and “transportation by air” to mean the consideration paid for the discrete act of moving a person by air. The court supports the ordinary meaning of “transportation” with period dictionaries and emphasizes that “for” denotes an exchange for the service itself—akin to a “fare,” not an ownership-program retainer.

2. Context and statutory mechanics: domestic segments, timing, layovers, and collection design

The court reinforces its reading through surrounding provisions that presuppose discrete trips: “domestic segments,” where the travel “begins,” and Congress’s 1970 inclusion of layovers and “deadhead” service (flight-adjacent components still tied to specific itineraries). It also emphasizes the tax’s collection architecture under § 4291—carrier collects from passenger and remits semi-monthly—suggesting Congress expected a determinate, transaction-level tax base.

This architecture becomes decisive when applied to fixed fees: if the collector cannot tell ex ante what portion of a management fee corresponds to taxable domestic transportation versus untaxed foreign transportation (or to no transportation at all), the statute’s presumed administrability breaks down.

3. Regulations cut against the government’s “reasonably necessary” theory

A major analytical lever is 26 C.F.R. § 49.4261-8(f)(5) (2012), which excludes separable charges like “parking,” “[de]icing,” and “sanitation.” The court uses these exclusions to rebut the government’s claimed interpretive principle that the tax reaches all “reasonably necessary” costs of air transportation. If even necessary flight conditions can be excluded when separable, then fixed overhead and management—further removed from a particular flight—cannot be shoehorned into “for transportation.”

4. Canons: (i) no tax by implication; (ii) heightened clarity for third-party collectors

The opinion applies two related canons:

  • Anti-expansion canon: Under Gould v. Gould and related authority, courts will not “extend” tax statutes beyond their “clear import.” Here, the government’s reading would swell a “ticket tax” into an all-inputs excise.
  • Third-party collector clarity canon: Under Central Illinois Pub. Serv. Co. v. United States, the IRS cannot impose a third-party withholding/collection duty without “precise and not speculative” notice grounded in binding sources (statutes, binding regulations, judicial decisions).

The court underscores why third-party clarity matters in this setting: undercollection triggers secondary liability and potential officer liability (with the opinion citing § 6672(a) risks and Nakano v. United States), while overcollection can bring civil penalties (Sigmon v. Sw. Airlines Co.) and private litigation (In re Air Transp. Excise Tax Litig.), and refunds require carriers to repay customers first under § 6415(a).

5. Rejection of nonbinding guidance as “notice”

The court draws a bright line: technical advice memoranda, an “Audit Technique Guide,” and internal/private legal risk assessments cannot create binding obligations for other taxpayers, especially given 26 U.S.C. § 6110(k)(3) and 26 C.F.R. § 601.601(d)(1)’s explicit nonprecedential rule for unpublished rulings. The opinion treats the government’s reliance on these materials as an attempt to substitute enforcement posture for law.

6. Deference: why Skidmore does not carry the day

The government invoked Rev. Rul. 80-31 and Rev. Rul. 2006-52 and their “reasonably necessary” phrasing. The court responds in two steps: (1) the “reasonably necessary” gloss does not track the statutory words (“for transportation”) and lacks stopping points; and (2) the rulings’ “one-page analysis” and incompatibility with regulations and enforcement history deprive them of persuasive force under Christensen v. Harris County and Skidmore v. Swift & Co..

C. Impact

  • Substantive limitation on § 4261’s pre-2012 reach (Sixth Circuit): The decision squarely rejects the IRS’s attempt to treat fixed fractional-jet management/membership fees as “amount[s] paid for” “transportation by air,” confining the “ticket tax” to flight-linked usage charges.
  • Stronger enforcement constraint via Central Illinois: Even beyond aviation excise taxes, the opinion strengthens a practical rule for any regime that deputizes private parties as tax collectors: absent binding, administrable, prospective standards, the government cannot impose retroactive collector liability.
  • Administrative-law signal: By treating informal guidance as insufficient and highlighting nonprecedential rules for technical advice memoranda, the opinion pressures the IRS to use regulations (or obtain statutory changes) when attempting to expand tax collection duties—particularly where allocation problems (domestic vs. foreign; used vs. unused access) are endemic.
  • Interpretive-canons debate (Murphy concurrence): The concurrence invites future litigants to press the Supreme Court to reconcile the pro-taxpayer canon line (Gould v. Gould and predecessors) with the “legislative grace” line (New Colonial Ice Co. v. Helvering and successors). While not outcome-determinative here, it frames a live, recurring interpretive conflict.

IV. Complex Concepts Simplified

  • “Excise tax”: A tax on a transaction or activity (here, paying for domestic air transportation), not on income.
  • “Amount paid for transportation by air”: The price exchanged for the trip itself—what the court analogizes to a “fare” or “ticket”—not every business expense that makes flights possible.
  • “Third-party collector liability”: The tax is owed by the customer, but the law makes the seller/carrier responsible if it fails to collect. The Sixth Circuit stresses that this deputization requires clear, advance rules.
  • “Technical advice memorandum”: IRS advice issued to a specific taxpayer; by law it does not bind others and cannot serve as precedent in other cases.
  • “Skidmore respect”: A court may consider an agency’s nonbinding interpretation only insofar as it is persuasive. The court found the cited revenue rulings unpersuasive and unworkable.
  • “Allocation problem”: If a fixed fee arguably supports both taxable domestic flights and non-taxable foreign flights (or supports mere readiness without any flights), the collector would need a rule to split the fee—yet the IRS supplied no binding allocation method.

V. Conclusion

Flight Options, LLC v. United States establishes (in the Sixth Circuit) that the pre-2012 § 4261 “ticket tax” does not extend beyond flight-by-flight usage charges to fixed fractional-jet management and membership fees. The opinion grounds that result in text, statutory context, and regulations—and, critically, in the principle from Central Illinois Pub. Serv. Co. v. United States that the government may not impose third-party collection liability without “precise and not speculative” notice rooted in binding law. Judge Murphy’s concurrence amplifies the decision’s broader significance by spotlighting unresolved Supreme Court tensions over tax interpretive canons, signaling that future tax cases may increasingly turn on clarifying which canon governs and when.
