Court Rejects Estate Tax Discount After Deathbed Partnership

What Happened

The United States Court of Appeals for the Fifth Circuit delivered a significant ruling in Estate of Anne Milner Fields v. Commissioner on June 8, 2026, addressing the boundaries of estate tax planning during terminal illness. The case centered on Anne Milner Fields, a successful businesswoman who suffered from Alzheimer's disease. During her final weeks, her great-nephew and agent Bryan Milner orchestrated the transfer of approximately $17 million in assets into a newly formed limited partnership called AM Fields, LP.

The timeline proved crucial to the court's analysis. The partnership was formed in late May 2016, the bulk of assets were transferred by mid-June, and Ms. Fields passed away on June 23, 2016. The estate valued her partnership interest at approximately $11 million on the estate tax return, claiming a $6 million discount from the underlying asset values. The Internal Revenue Service challenged this valuation under Section 2036(a) of the Internal Revenue Code, which includes transferred assets in the gross estate when the decedent retained certain interests, unless the transfer was a bona fide sale for adequate consideration.

The Fifth Circuit affirmed the Tax Court's decision, rejecting the estate's claimed business purposes and upholding both the tax deficiency and a 20% accuracy-related penalty. The court found that the partnership creation was motivated primarily by tax reduction rather than legitimate business purposes, making the transferred assets includible in the gross estate at their full $17 million value.

What It Means

This ruling reinforces the strict scrutiny courts apply to estate planning transactions conducted during periods of declining health or terminal illness. The decision highlights the challenge estates face when attempting to justify substantial valuation discounts through family limited partnerships created shortly before death. Under current federal estate tax law, estates exceeding $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jan 2, 2026 face a top tax rate of 40%26 USC 2001(c)Verified Jan 2, 2026, making these discount strategies particularly valuable for large estates.

The court's analysis focused on the objective evidence of the partnership's purpose, not the theoretical benefits it might have provided. The estate argued the partnership served three non-tax purposes: addressing power of attorney limitations, consolidating asset management, and preventing elder abuse. However, the court found these justifications were "post hoc theoretical justifications" rather than actual motivations. The existing power of attorney was already functional, the assets offered no obvious synergies, and the rapid timeline suggested tax motivation rather than business planning.

The ruling also demonstrates the risks of relying on professional advice without ensuring that advice specifically addresses the valuation methods used. The estate's reasonable cause defense failed because the accountant had not specifically advised the valuation approach taken on the return. The court emphasized that a $6 million discount should have appeared "too good to be true" to a reasonable person, triggering additional scrutiny and documentation requirements. This case serves as a warning that engaging professionals does not automatically provide protection from penalties if the underlying transaction lacks substance or proper documentation.

Context from SimplyTrust

Estate planning requires careful timing and documentation to achieve intended tax benefits while maintaining legitimacy. The Fields case illustrates why estate planning should occur well before health crises, when clear business purposes can be established and documented. For families concerned about estate tax exposure, understanding the difference between estate tax and inheritance tax becomes crucial, as these taxes operate differently and affect different parties.

While complex partnership structures require sophisticated legal and tax advice, basic estate planning tools like revocable living trusts offer straightforward benefits without the scrutiny applied to discount strategies. A revocable trust provides asset management during incapacity and avoids probate at death, addressing many of the same concerns the Fields estate claimed motivated their partnership formation. For estates approaching federal exemption thresholds, proper planning should begin years before health issues arise, ensuring sufficient time to establish legitimate business purposes and document the rationale for any planning structures.
