Williams v. Commissioner: Casualty Losses, Charitable Deductions, and Substantiation in the Wake of Hurricane Michael

The $60,000 Storm: Taxpayers Fight IRS Over Hurricane Michael Deductions

The stakes couldn’t have been higher for Brenton E. Williams and Octavia P. Williams, a military family whose home in Panama City, Florida, was reduced to splinters when Hurricane Michael made landfall as a Category 5 storm on October 10, 2018. The disaster, later declared a Federally Declared Disaster (FDD) under FEMA DR-4399, left the Williamses staring down a $34,252 tax deficiency for 2018 and 2019, plus $6,851 in accuracy-related penalties under § 6662(a). The United States Tax Court delivered its final word on September 23, 2026, in T.C. Memo. 2026-91: the Williamses lost on every deduction and penalty. The court’s ruling hinged on a single, unforgiving principle—substantiation. Without receipts, appraisals, or credible documentation, the IRS and the Tax Court alike refused to entertain claims for casualty losses, charitable contributions, or unreimbursed moving expenses. The case serves as a cautionary tale for disaster victims and military taxpayers alike, underscoring that when the IRS demands proof, the absence of it is not a technicality—it’s a disqualifier.

A Military Family’s Home Destroyed: The Facts Behind the Dispute

Octavia P. Williams, a senior airman in the U.S. Air Force, was stationed at Tyndall Air Force Base (Tyndall) near Panama City, Florida, when Hurricane Michael made landfall on October 10, 2018. The storm, later classified as a category 5 hurricane, devastated the Florida Panhandle and left Tyndall “virtually levelled,” according to a 2023 Air Force report. The Williams family’s home, located on the base, sustained extensive damage and became uninhabitable, forcing them to evacuate to Debary, Florida. Octavia continued working at Tyndall until her subsequent transfer to Patrick Air Force Base (now Patrick Space Force Base) in central Florida.

Within ten days of the storm, Octavia and her spouse returned to Tyndall to assess the damage. They documented the destruction with photographs of the first floor but were unable to inspect the second floor due to safety hazards. Without a detailed inventory or appraisals, they relied on memory to estimate the loss of personal property, including furniture, electronics, appliances, and clothing. They submitted an insurance claim to USAA, which issued a claim letter dated November 3, 2020, acknowledging losses in the living room and primary bedroom. USAA paid $34,500 for personal property coverage, $4,724 for loss of use, $1,422 for additional living expenses, $500 for refrigerated products, $3,000 for a personal computer, and $10,000 under a separate valuable personal property policy for jewelry and watches. The total payout of $54,146 fell short of the $61,000 personal property loss claimed by the Williamses, whose replacement value for valuable personal property exceeded the policy limit by $19,382.

In the storm’s aftermath, the Williamses donated undamaged belongings to Goodwill and the Airman’s Attic, a nonprofit serving military families, but they did not obtain contemporaneous written acknowledgments (CWAs) as required under section 170(f)(8) and Treasury Regulation § 1.170A-13(f). They also contributed items to community members in need, though no records of these donations were retained.

For tax years 2018 and 2019, the Williamses filed joint Forms 1040 with tax preparer Bruce Baugh. On their 2018 return, they claimed a casualty loss deduction of $182,037 under section 165(h) for Hurricane Michael damage, reducing the amount by the $100 statutory floor and 10% of their adjusted gross income. Their reported tax due was $207, but the IRS later asserted a corrected liability of $30,488. On their 2019 return, they claimed a $27,787 noncash charitable contribution deduction for donations to Goodwill, supported only by self-prepared descriptions of donated items such as “Electronics, Computer Equipment” ($8,500 FMV), “High End Clothing” ($7,600 FMV), and “Furniture and Equipment” ($11,687 FMV). They attached Form 8283 but provided no appraisals or receipts. Additionally, they deducted $5,619 in state and local personal property taxes and $4,635 in state and local general sales taxes, along with $22,592 in vehicle mileage expenses for Octavia’s commute from Debary to Tyndall and later Patrick, reported as an adjustment to income on Form 2106. Their reported tax due for 2019 was $6,959, though the IRS asserted a corrected liability of $22,923.

Throughout the process, the Williamses lacked appraisals, contemporaneous written acknowledgments for charitable donations, and receipts for claimed taxes and mileage—gaps that would later prove decisive.

The IRS Strikes Back: Why the Commissioner Disallowed Every Deduction

The IRS examiner’s disallowance of every claimed deduction in the Williamses’ 2018 and 2019 returns was not merely a rejection of numbers—it was a systematic dismantling of unsupported claims, each grounded in the Tax Code’s strict substantiation requirements. The examiner’s determination, later upheld by the Tax Court, hinged on the Williamses’ failure to meet the evidentiary standards for casualty losses, charitable contributions, personal property taxes, vehicle expenses, and even military-related travel deductions. The stakes were clear: the IRS asserted a corrected tax liability of $22,923—a $15,964 increase over the Williamses’ reported $6,959—and sought to impose accuracy-related penalties under § 6662(a) for substantial understatements and negligence.

The examiner’s disallowances were not arbitrary. They were the direct application of statutory and regulatory mandates that the Williamses either ignored or misunderstood. The examiner disallowed:

• $162,075 in casualty loss deductions for 2018, citing § 165(h)’s requirement that taxpayers prove both the occurrence of a casualty and the amount of loss sustained;
• $27,787 in noncash charitable contributions for 2019, because the Williamses lacked contemporaneous written acknowledgments under § 170(f)(8) or qualified appraisals for donations exceeding $5,000;
• $5,619 in state and local personal property taxes and $2,957 in general sales taxes, due to the absence of receipts or other substantiation;
• $26,289 in vehicle expenses for Octavia Williams’ commute, including $22,592 in mileage, because the Williamses could not provide logs, receipts, or even a coherent explanation of the claimed deductions; and
• Accuracy-related penalties under § 6662(a), asserting that the understatements were substantial and attributable to negligence.

The examiner’s findings were not merely persuasive—they were dispositive. The Tax Court later held that the Williamses “did not establish that a casualty occurred and that any deductible loss was sustained,” and that their claimed deductions “were not substantiated.” T.C. Memo. 2026-11, at *6 (Sept. 15, 2026). The IRS’s position was not an overreach; it was the enforcement of the Tax Code’s foundational principle: no deduction without proof.

The Casualty Loss Deduction: A $162,075 Gap in Proof

The Williamses claimed a $162,075 casualty loss deduction for 2018, attributing it to damage from Hurricane Michael, which struck the Florida Panhandle in October 2018. The examiner rejected the claim entirely, citing § 165(h), which permits deductions for casualty losses only if the taxpayer substantiates:

1. The occurrence of a casualty event (e.g., a hurricane declared a federally declared disaster under the Stafford Act);
2. The amount of loss sustained, calculated as the lesser of the property’s adjusted basis or its decrease in fair market value (FMV) due to the casualty, reduced by insurance reimbursements and statutory floors; and
3. The timing of the loss, which must occur in the taxable year claimed.

The Williamses provided no appraisals, no insurance claims, and no third-party documentation to support their loss claim. Instead, they relied on memories and photographs—evidence the examiner and later the Tax Court found insufficient. The court held: “Petitioners did not establish that a casualty occurred and that any deductible loss was sustained.” T.C. Memo. 2026-11, at *6. The IRS’s refusal to accept unsupported claims was not an abuse of discretion; it was the Tax Court exercising its power to enforce the substantiation requirements of § 165(h).

The Charitable Contribution Deduction: $27,787 in Unsubstantiated Donations

The Williamses claimed $27,787 in noncash charitable contributions for 2019, including donations of clothing, household items, and possibly vehicles. The examiner disallowed the entire deduction, citing § 170(f)(8), which requires:

• A written acknowledgment (WA) from the charity, detailing the donated property (but not its value), and
• For donations exceeding $5,000, a qualified appraisal attached to the tax return.

The Williamses provided no contemporaneous written acknowledgments from any charity, nor did they obtain appraisals for high-value items. The Tax Court later affirmed the disallowance, noting that “the contributions were not substantiated” under § 1.170A-13(f). T.C. Memo. 2026-11, at *6. The IRS’s position was not a rejection of generosity; it was the enforcement of § 170(f)(8)’s strict substantiation rules, a power the Tax Court has repeatedly upheld in cases like T.C. Memo. 2021-133 (disallowing a $200,000 art donation due to a self-prepared appraisal).

The Personal Property and Sales Tax Deductions: $8,576 in Undocumented Expenses

The Williamses claimed $5,619 in state and local personal property taxes and $2,957 in general sales taxes for 2019. The examiner disallowed both, citing the lack of receipts or other documentation. Under § 164, taxpayers may deduct state and local taxes only if they can substantiate the payments. The Williamses provided no canceled checks, no property tax bills, and no receipts—just as the court later noted, “the expense was not substantiated.” T.C. Memo. 2026-11, at *6. The IRS’s refusal to accept vague claims was not arbitrary; it was the Tax Court enforcing the substantiation requirements of § 164.

The Vehicle Expense Deduction: $26,289 in Unverified Mileage

The Williamses claimed $26,289 in vehicle expenses for 2019, including $22,592 in mileage for Octavia Williams’ commute from Debary to Tyndall Air Force Base (later Patrick Air Force Base). The examiner disallowed the entire amount, citing § 274(d), which requires taxpayers to substantiate:

• The amount of each expense (e.g., mileage logs),
• The time and place of the expense, and
• The business purpose of the expense.

The Williamses could not provide mileage logs, receipts, or even a clear explanation of the claimed deductions. The examiner initially argued the lack of substantiation, but the IRS later shifted its position, asserting that Octavia was not a reservist and thus ineligible for the deduction. The Tax Court did not reach the reservist issue, instead holding that “petitioners did not provide the information needed to support the deduction.” T.C. Memo. 2026-11, at *6. The IRS’s evolving argument—from lack of substantiation to ineligibility—demonstrated its flexibility in challenging claims, but the court’s focus remained on the Tax Code’s substantiation requirements, not the IRS’s shifting positions.

The Accuracy-Related Penalties: $4,480 in Additional Liability

The examiner also imposed accuracy-related penalties under § 6662(a), asserting that the Williamses’ understatements were substantial and attributable to negligence. The penalties added $4,480 to the corrected tax liability, bringing the total asserted deficiency to $22,923. The IRS relied on § 6662(b)(1) (negligence) and § 6662(b)(2) (substantial understatement), arguing that the Williamses’ failure to substantiate deductions demonstrated a disregard for tax rules.

The penalties were not automatic. The examiner’s supervisor, Pamela Josephson, signed a Civil Penalty Approval Form on June 29, 2021, satisfying § 6751(b)’s requirement for supervisory approval before assessment. The Tax Court later upheld the penalties, holding that the Williamses’ lack of documentation and inconsistent claims supported the IRS’s position. T.C. Memo. 2026-11, at *6. The IRS’s imposition of penalties was not punitive; it was the Tax Court enforcing the penalty provisions of § 6662(a), a power it has repeatedly affirmed in cases like Chai v. Commissioner, 851 F.3d 190 (2d Cir. 2017), and Graev v. Commissioner, 149 T.C. 485 (2017).

The IRS’s Power: Enforcing the Tax Code’s Substantiation Requirements

The Williamses’ case was not about the IRS overreaching; it was about the IRS exercising its authority to enforce the Tax Code’s substantiation requirements. The examiner’s disallowances were not based on speculation or bias; they were based on clear statutory and regulatory mandates that the Williamses failed to meet. The Tax Court’s later affirmation of the IRS’s position demonstrated the court’s willingness to uphold the IRS’s authority when taxpayers fail to substantiate their claims.

The IRS’s power in this case was not about raising revenue; it was about ensuring compliance with the Tax Code’s foundational principles. The Williamses’ lack of documentation—whether for casualty losses, charitable contributions, or vehicle expenses—was not a minor oversight; it was a failure to meet the Tax Code’s evidentiary standards. The IRS’s refusal to accept unsupported claims was not an abuse of discretion; it was the Tax Court exercising its power to enforce the Tax Code.

The Court’s Verdict: No Deductions Without Proof

The Tax Court’s ruling in Williams was not merely a rejection of unsupported claims—it was a decisive exercise of judicial authority to enforce the Tax Code’s foundational evidentiary standards. Judge Marshall’s opinion, filed in T.C. Memo. 2026-91, systematically dismantled each of the Williamses’ deductions, not because the IRS lacked authority to challenge them, but because the petitioners failed to meet the statutory and regulatory burdens of proof. The court’s reasoning hinged on the Tax Code’s strict substantiation requirements, which the Williamses treated as optional. In doing so, the Tax Court reaffirmed its power to police compliance with the law, even when the stakes involved a military family’s financial recovery from a federally declared disaster.

Casualty Loss (§ 165): The $182,037 Illusion

The court began by addressing the Williamses’ $182,037 casualty loss deduction for Hurricane Michael damage, a claim that hinged on § 165(h), which permits deductions for losses attributable to federally declared disasters. Section 165(a) allows deductions for losses not compensated by insurance, but § 165(h)(5)(A) narrows this to losses from federally declared disasters—a critical limitation post-2017. Hurricane Michael qualified, but the court emphasized that substantiation is non-negotiable.

The Williamses argued that their photos of the first floor and memories of destroyed items sufficed, but the court held otherwise. Treasury Regulation § 1.165-7(b)(1) requires the loss to be measured by the lesser of the property’s fair market value (FMV) before and after the casualty or its adjusted basis. The regulation further mandates that FMV be established by a competent appraisal unless other evidence is provided. The Williamses had no appraisal, no list of destroyed items, and no credible method to quantify their losses beyond vague recollections.

The court quoted its own precedent in Zilberberg v. Commissioner, T.C. Memo. 2011-5, stating: "We ordinarily look at the proof he offers in the form of documentation and testimony." The Williamses’ photos and insurance claim letters were insufficient. Their USAA payout of $34,500 for personal property coverage—far below their claimed $182,037 loss—highlighted the gap between their assertions and verifiable evidence. The court concluded: "On the record before us, we are unable to find that petitioners have substantiated their reported casualty loss." The deduction was fully disallowed.

Charitable Contributions (§ 170): The $27,787 Void

The Williamses claimed a $27,787 noncash charitable contribution deduction for donations to Goodwill and the Airman’s Attic in 2019. Section 170(a)(1) allows deductions for charitable contributions, but § 170(f)(8) imposes strict substantiation requirements. For contributions over $250, taxpayers must obtain a contemporaneous written acknowledgment (CWA) from the charity, detailing the donation’s nature but not its value. For contributions over $5,000, Treasury Regulation § 1.170A-13(f) requires a qualified appraisal and the filing of Form 8283.

The Williamses had no CWAs from Goodwill or the Airman’s Attic. They claimed to have donated electronics, clothing, and furniture, but the court noted that "they did not have any contemporaneous written acknowledgments from either organization." Without CWAs, the deduction was automatically disallowed under § 170(f)(8). The court further observed that even if CWAs had been provided, the Williamses failed to obtain appraisals for items valued over $5,000, as required by regulation. The court held: "The contributions were not substantiated." The $27,787 deduction vanished.

Personal Property and Sales Taxes (§ 164): The $10,254 Disappearance

The Williamses claimed $5,619 in personal property taxes and $4,635 in state and local general sales taxes for 2019. Section 164 allows deductions for state and local taxes, but substantiation is mandatory. The court found that the Williamses provided no receipts, bank records, or other documentation to support these expenses. The IRS examiner disallowed the personal property taxes entirely, and the court upheld this decision, stating: "The expense was not substantiated." The sales taxes were partially disallowed ($2,957 of the $4,635 claimed), leaving the Williamses with no deductible state and local tax expenses for 2019.

Reservist Mileage (§ 62(a)(2)(E)): The $26,289 Rejection

Octavia Williams claimed $26,289 in vehicle mileage expenses for commuting to Tyndall Air Force Base and Patrick Space Force Base in 2019. Section 62(a)(2)(E) allows above-the-line deductions for reservists traveling more than 100 miles from home for reserve duties. However, the court noted that Octavia was an active-duty Air Force member, not a reservist, during the years in issue. The IRS examiner disallowed the deduction, and the court agreed: "Petitioners did not provide the information needed to support the deduction." The Williamses’ attempt to claim active-duty commuting expenses as reservist travel expenses collapsed under the plain language of the statute.

Penalties (§ 6662(a)): The $6,851 Confirmation

The IRS imposed § 6662(a) accuracy-related penalties for substantial understatements of tax or negligence. Section 6662(a) imposes a 20% penalty on underpayments attributable to negligence or disregard of rules. The IRS satisfied § 6751(b) by obtaining written supervisory approval from Pamela Josephson on June 29, 2021, before assessing penalties. The court upheld the penalties, finding that the Williamses’ lack of documentation for multiple deductions constituted negligence. The court held: "The burden of proof remains on petitioners, and they have failed to meet it." The penalties stood: $5,498 for 2018 and $1,353 for 2019.

The Court’s Power in Enforcing the Tax Code

The Tax Court’s ruling in Williams was not a mere technicality—it was a declaration that the Tax Code’s rules apply equally to all taxpayers, regardless of circumstance. The court did not bend to the emotional weight of a military family’s disaster recovery; instead, it upheld the IRS’s authority to demand compliance with the law’s evidentiary standards. The Williamses’ failure to substantiate their deductions was not a minor oversight—it was a violation of the Tax Code’s foundational principles. The Tax Court’s decision reaffirmed that documentation is not optional, and the IRS’s refusal to accept unsupported claims was not an abuse of discretion but the exercise of its power to enforce the law.

The court’s opinion closed with a blunt reminder: "Taxpayers are permitted deductions only as a matter of legislative grace, and only as specifically provided by statute." The Williamses’ deductions were not provided by statute—because they were not substantiated. The Tax Court’s verdict was final: no deductions without proof.

What This Means for Taxpayers: Lessons from the Williams Case

The Williams decision underscores a harsh truth: substantiation is not optional, and the Tax Court’s refusal to accept unsupported claims was not an abuse of discretion but the exercise of its power to enforce the law.

For taxpayers—especially those reeling from natural disasters or serving in the military—the ruling delivers four critical lessons that will shape future filings.

First, casualty loss deductions under § 165(h) demand ironclad proof. Memories, photos, and even receipts for replacement items are insufficient. The court made clear that appraisals, insurance claims, and contemporaneous documentation are the only acceptable forms of evidence. In the Williamses’ case, their failure to substantiate the value of destroyed personal property—despite claiming $60,000 in losses—sealed their fate. The Tax Court held that "taxpayers are permitted deductions only as a matter of legislative grace, and only as specifically provided by statute." This means that for federally declared disasters like Hurricane Michael, taxpayers must document the fair market value before and after the event, subtract insurance reimbursements, and apply the statutory floors ($100 per event and 10% of AGI). No shortcuts will suffice.

Second, charitable contributions—particularly noncash donations—require meticulous compliance with § 170(f)(8) and § 1.170A-13(f). The Williamses’ attempt to deduct high-value items without a qualified appraisal or written acknowledgment from the charity was doomed. The court’s opinion implicitly rejected their reliance on vague recollections, reinforcing that contemporaneous written acknowledgments and appraisals for items over $5,000 are mandatory. Future donors must ensure charities provide detailed receipts and, for high-value items, secure an appraisal from a qualified appraiser before filing. The IRS’s position here was not merely administrative overreach; it was the enforcement of statutory mandates that the court treated as non-negotiable.

Third, military taxpayers cannot claim reservist travel deductions under § 62(a)(2)(E) without strict adherence to the rules. The Williamses’ attempt to deduct travel expenses—likely including meals and lodging—would have failed even if their other deductions had been substantiated, because reservist travel must exceed 100 miles from home and be directly tied to reserve duties. The court’s emphasis on documentation of mileage, orders, and receipts serves as a warning to reservists: track every mile, every meal, and every overnight stay, or risk disallowance. The IRS’s refusal to bend on this point reflects its authority to enforce the plain language of the statute, leaving no room for informal records or after-the-fact reconstructions.

Finally, accuracy-related penalties under § 6662(a) apply even when deductions are claimed in good faith. The court’s decision to sustain the IRS’s penalty determinations—despite the Williamses’ apparent sincerity—highlights that reasonable cause defenses are difficult to sustain without contemporaneous records. The IRS’s supervisory approval under § 6751(b), which was properly obtained before assessment, further underscored the court’s deference to the agency’s procedural compliance. This sends a clear message: taxpayers bear the burden of proof, and the Tax Court will not hesitate to enforce penalties when that burden is unmet, regardless of intent.

For future taxpayers, the Williams case is a cautionary tale. Whether facing a hurricane, a wildfire, or the demands of military service, documentation is the difference between a deduction and a disallowance. The Tax Court’s ruling was not just about the Williamses’ $60,000 loss—it was about asserting the court’s authority to interpret and enforce the tax laws as written. Taxpayers who ignore this lesson do so at their peril.
