Fields v. CIR: Fifth Circuit Tightens § 2036(a) Bona Fide Sale Scrutiny for Deathbed FLP Discounts and Affirms “Too Good to Be True” Negligence Penalty

Court: United States Court of Appeals for the Fifth Circuit
Date: June 8, 2026
Case: Estate of Anne Milner Fields, Deceased, Bryan K. Milner, Executor v. Commissioner of Internal Revenue (No. 25-60403)

I. Introduction

Fields v. CIR is an estate-tax valuation dispute arising from a rapid, late-in-life restructuring of Anne Milner Fields’s wealth. As Fields’s health sharply deteriorated, her agent and great-nephew, Bryan K. Milner, transferred approximately $17 million of her assets into a newly formed limited partnership, AM Fields, LP. After Fields died ten days after the final major transfer and shortly after entering hospice, the Estate reported the decedent’s limited-partner interest at roughly $10.877 million—reflecting valuation discounts associated with a limited partnership interest—rather than reporting the full value of the underlying contributed assets.

The IRS invoked I.R.C. § 2036(a) to “pull back” the transferred property into the gross estate (thus valuing the estate by reference to the contributed assets rather than the discounted partnership interest) and also imposed a 20% accuracy-related penalty under I.R.C. § 6662. The Tax Court agreed with the IRS, and the Fifth Circuit affirmed.

Key issues

  • § 2036(a) bona fide sale exception: Did the transfers to AM Fields, LP serve a substantial non-tax purpose so as to qualify as a “bona fide sale for an adequate and full consideration”?
  • Accuracy-related penalty: Was the Estate negligent, and did it prove “reasonable cause” and “good faith” (including reliance on professional advice) to avoid the penalty?

II. Summary of the Opinion

The Fifth Circuit affirmed the Tax Court’s deficiency and penalty determinations. On § 2036(a), the court held the Estate failed to prove that the partnership formation and asset transfers were motivated by a substantial non-tax purpose. Accordingly, the bona fide sale exception did not apply, and the transferred assets’ values were includible in the gross estate.

On penalties, the court held the Tax Court did not clearly err in finding negligence and in rejecting the Estate’s reasonable-cause/good-faith defense. A roughly $6 million reduction in reportable assets was deemed something a reasonable person—particularly one with Milner’s finance background—should have recognized as “too good to be true,” and the record did not establish competent professional advice affirmatively endorsing the Estate’s reporting position.

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. Standards of review and deference to the Tax Court

  • Ray v. Comm'r, 13 F.4th 467 (5th Cir. 2021): The Fifth Circuit reiterated its framework: factual findings are reviewed for clear error; legal conclusions are reviewed de novo. The court also treated reasonable-cause/good-faith determinations as factual findings reviewed for clear error, substantially constraining appellate reweighing of credibility and motive evidence.
  • Klamath Strategic Inv. Fund ex rel. St. Croix Ventures v. United States, 568 F.3d 537 (5th Cir. 2009): Quoted for the proposition that transaction characterization for tax purposes is a legal question, while the underlying factual predicates are reviewed for clear error—important here because “bona fide sale” analysis turns heavily on objective facts and motive inferences.
  • Strangi v. Comm'r, 417 F.3d 468 (5th Cir. 2005): Central in two ways:
    • It supplied the Fifth Circuit’s approach that the bona fide sale inquiry is an “objective” one asking whether the transfer serves a substantial business or other non-tax purpose.
    • It reinforced deference to the Tax Court on the ultimate factual finding of whether a substantial non-tax purpose actually motivated the transaction.
  • Otto Candies, L.L.C. v. Nippon Kaiji Kyokai Corp., 346 F.3d 530 (5th Cir. 2003): Cited through Strangi for the “definite and firm conviction that a mistake has been made” formulation of clear-error review, underscoring why the Estate’s challenge was difficult absent a strong evidentiary record.

2. § 2036(a) doctrine and the bona fide sale exception (especially for family entities)

  • Kimbell v. United States, 371 F.3d 257 (5th Cir. 2004): Provided doctrinal framing: § 2036(a) recaptures certain inter vivos transfers unless the transfer is a bona fide sale for adequate and full consideration. Kimbell is also the Fifth Circuit’s key comparator for when a partnership transfer can qualify—there, “working interests” requiring active management supported a non-tax purpose. The Fields court distinguished that type of operational reality from the largely passive, professionally managed portfolio here.
  • Estate of Bongard v. Comm'r, 124 T.C. 95 (2005): Quoted for an oft-invoked limitation on family-entity planning: the non-tax rationale must be a “significant factor” and an “actual motivation,” not merely a “theoretical justification.” This language anchored the Fifth Circuit’s acceptance of the Tax Court’s view that the Estate’s asserted purposes were post hoc rationalizations.
  • Estate of Harper v. Comm'r, 83 T.C.M. (CCH) 1641 (2002): Used to reject the notion that simply pooling disparate, mostly passive assets automatically creates management “synergies” or business benefits sufficient to show a substantial non-tax purpose. The Fifth Circuit endorsed the Tax Court’s skepticism that “disparate” assets “promised no obvious synergies.”
  • Estate of Fields v. Comm'r, T.C.M. (RIA) 2024-090 (2024): While not a precedent in the same sense as circuit authority, it is the foundational trial-level opinion whose factual findings and credibility determinations the Fifth Circuit largely insulated under clear-error review. The Fifth Circuit’s analysis repeatedly deferred to the Tax Court’s timeline and motive inferences.

3. Penalty doctrine: negligence, reliance, and “too good to be true”

  • Sun v. Comm'r, 880 F.3d 173 (5th Cir. 2018): Supplied the Fifth Circuit’s articulation that negligence is “strongly indicated” where a claimed benefit appears “too good to be true,” tying directly to the court’s view of the $6 million valuation reduction.
  • Neonatology Assocs., P.A. v. Comm'r, 299 F.3d 221 (3d Cir. 2002): Used to reinforce the intuition that an unusually large tax advantage is a red flag requiring heightened skepticism and inquiry by a reasonable taxpayer.
  • Swayze v. United States, 785 F.2d 715 (9th Cir. 1986) (quoted via Klamath): Emphasized that reliance turns on the “quality and objectivity” of professional advice, not the mere fact of hiring professionals.
  • 26 C.F.R. § 1.6662-3(b)(1) and 26 C.F.R. § 1.6664-4(b): The regulations supplied the operative definitions and the “most important factor” in reasonable-cause analysis: the taxpayer’s effort to assess proper liability. The Fifth Circuit applied these to conclude the Estate’s record did not show an adequate inquiry or competent advice endorsing the reporting position.

B. Legal Reasoning

1. The § 2036(a) framework and what was actually contested

Section 2036(a) generally includes in the gross estate property the decedent transferred during life while retaining certain lifetime benefits, unless the transfer falls within the “bona fide sale for an adequate and full consideration” exception. In Fields, the appeal effectively narrowed to a single question: whether the partnership transfers qualified as a “bona fide sale.” The Fifth Circuit noted the Estate did not contest (on appeal) the Tax Court’s retention-of-enjoyment conclusion, and it also did not contest the Tax Court’s finding of “adequate and full consideration.” That left only whether there was a substantial non-tax purpose—treated as an objective inquiry into actual motivation supported by objective evidence.

2. Why the Estate’s asserted non-tax purposes failed

(a) Fixing purported power-of-attorney shortcomings

The Estate argued AM Fields solved succession and institutional-resistance problems with the POA. The Fifth Circuit agreed with the Tax Court that these points did not show an actual motivating non-tax purpose:

  • Succession rationale was internally weak: Fields had named successor agents; no contemporaneous evidence showed that succession was a pressing operational problem. In addition, AM Fields required unanimous consent for management succession—undercutting the claim it “solved” succession risk.
  • “Banks won’t honor the POA” was contradicted by conduct: Milner used the POA to transfer roughly $17 million into the partnership rapidly, suggesting the POA was functional when it mattered most.
  • Lack of supporting evidence: The record did not substantiate a “continuous” pattern of POA resistance by institutions.
(b) Consolidation/streamlining of complex assets

The Fifth Circuit accepted the Tax Court’s distinction between assets requiring active business management and assets that are passive or already professionally managed. Here, key assets included a brokerage account managed by Wells Fargo/UBS, bank shares producing dividends, and a tree farm managed by a local company. Pooling such assets into a partnership, without more, did not show operational synergies or a genuine joint enterprise. The court contrasted this with Kimbell v. United States, where “working interests” in oil and gas supported an actual management-based non-tax purpose.

(c) Protection against fraud and elder abuse

The record showed two elder-abuse incidents in 2011 and 2013. The Fifth Circuit agreed it was reasonable for the Tax Court to discount this justification because the partnership was created years later—only after Fields’s condition entered rapid decline and mere weeks before death—making it unlikely that fraud protection was a significant motivating factor at formation.

3. The “bad facts” the court treated as highly probative of tax motivation

The Fifth Circuit emphasized that the Tax Court identified multiple objective indicators pointing away from a substantial non-tax purpose and toward tax-driven discount planning:

  • Deathbed timing: Formation and funding of AM Fields occurred rapidly in May–June 2016; Fields died shortly thereafter.
  • No earlier partnership discussion: The record lacked evidence of partnership planning until Fields’s health became dire.
  • No precipitating operational change: There was no significant non-tax change in the asset set requiring restructuring.
  • “Deeper discount” email: Estate counsel’s email to an appraiser explicitly seeking a “deeper discount” was treated as contemporaneous evidence of tax-discount focus.
  • Incapacity and conflicted execution: Fields was incapacitated; Milner appeared on both sides of the transactions, raising concerns about whether the arrangement reflected a genuine bargained-for exchange.
  • Liquidity depletion causing practical harm: Transfers left insufficient cash outside the partnership to fund bequests without partnership distributions—suggesting the structure was not designed around efficient estate administration.

With these facts, the Fifth Circuit held the Tax Court did not clearly err in finding no substantial non-tax purpose and thus no bona fide sale exception.

4. Penalty: why the “reasonable cause and good faith” defense failed

The Fifth Circuit affirmed the 20% penalty under I.R.C. § 6662 for negligence or disregard of rules. It endorsed the Tax Court’s view that reducing reportable assets by approximately $6 million via a valuation discount should have triggered heightened scrutiny by a reasonable taxpayer—especially Milner, given his finance background.

On reliance, the court treated the defense as evidentiary: to show reasonable cause and good faith based on professional advice, the Estate needed proof that a competent professional actually advised that the specific reporting position (discounted partnership interest rather than underlying asset values in light of § 2036) was proper. The Tax Court found, and the Fifth Circuit affirmed, that the record lacked such evidence; hiring professionals alone was not enough. Indeed, the record suggested estate counsel discussed potential tax benefits of the partnership, reinforcing the inference that tax reduction was understood as a primary objective rather than a collateral effect.

C. Impact

1. Practical effect on family limited partnership (FLP) planning in the Fifth Circuit

Fields reinforces a demanding, fact-intensive approach to the § 2036(a) bona fide sale exception, especially for late-stage transfers into family entities seeking valuation discounts. The opinion signals that courts will look past articulated rationales and test whether the record contains contemporaneous, objective evidence that a non-tax purpose was a significant actual motivator.

2. Evidentiary lessons: what taxpayers/estates must be prepared to show

  • Non-tax purpose must be real and timely: Planning initiated only after terminal decline, with no earlier operational rationale, will face skepticism.
  • “Streamlining” requires proof: Expect courts to demand evidence of actual management burdens, synergies, cost savings, governance improvements, or risk management—beyond conclusory assertions.
  • Professional reliance must be documented: To avoid penalties, estates should preserve written advice, scope of engagement, the facts supplied to advisers, and an explicit analysis of § 2036 risk.

3. Penalty exposure: discounts as a “red flag”

The opinion highlights that large valuation discounts can themselves create negligence risk when they produce outcomes that appear implausible without careful statutory analysis. Under Sun v. Comm'r and the regulations, a dramatic tax benefit increases the expected level of taxpayer diligence; “I hired professionals” is not a complete defense absent proof of high-quality, objective advice endorsing the position taken.

IV. Complex Concepts Simplified

A. What does I.R.C. § 2036(a) do?

Section 2036(a) prevents a person from reducing estate tax by giving away property in form while effectively keeping its benefits in substance. If the decedent transferred property before death but still effectively retained enjoyment, income, or control until death, the law generally treats the property as still part of the taxable estate.

B. What is the “bona fide sale for adequate and full consideration” exception?

Even if § 2036(a) would otherwise apply, the transfer is not pulled back into the estate if it was a genuine sale (not a mere reshuffling) for full value. In family-entity contexts, courts commonly require proof that the transaction had a substantial non-tax purpose that genuinely motivated it—because intra-family transfers can be structured to look like sales while functioning like estate-freeze devices.

C. What is “clear error” review and why does it matter?

“Clear error” is a highly deferential appellate standard for factual findings. Because motive and purpose are often inferred from timelines, documents, and credibility assessments, the Tax Court’s findings will usually stand unless the appellate court is firmly convinced a mistake occurred. That deference was outcome-determinative in Fields.

D. What is a § 6662 accuracy-related penalty and the “reasonable cause” escape hatch?

Section 6662 adds 20% to an underpayment attributable to negligence. Section 6664(c) can excuse the penalty if the taxpayer shows reasonable cause and good faith—often by demonstrating careful efforts to get the law right and reliance on competent advice. But reliance must be substantiated: the taxpayer must show what was asked, what facts were provided, and what professional conclusion was actually reached about the reporting position.

V. Conclusion

Fields v. CIR confirms that, in the Fifth Circuit, the § 2036(a) bona fide sale exception for transfers to a limited partnership depends on objective evidence of a substantial, actual non-tax motivation—not after-the-fact rationales. The court’s emphasis on deathbed timing, contemporaneous “discount” communications, passive asset character, and liquidity consequences illustrates the factual profile likely to defeat FLP-based valuation discounts under § 2036.

The decision also strengthens penalty-risk warnings: where an estate reporting position yields a striking reduction in taxable value, courts may expect heightened diligence and documented, objective professional advice. Absent that record, the “too good to be true” inference can support negligence and defeat reasonable-cause defenses.
