Valarie Lindsey v. Commissioner of Internal Revenue: Jurisdictional Dismissal Over Late-Filed Petition

The $17,000 Gamble: Taxpayer Loses Bid to Challenge IRS Deficiency Notice

The Tax Court’s September 24, 2026, decision in Valarie Lindsey v. Commissioner (T.C. Memo. 2026-94) delivered a stark reminder to taxpayers: the 90-day window to challenge an IRS deficiency notice is not a suggestion. Lindsey’s gamble to challenge $17,318 in proposed deficiencies and penalties—$8,163 for 2017 and $7,935 for 2018, plus $3,220 in accuracy-related penalties—ended in total defeat when the court dismissed her petition for lack of jurisdiction. The case underscores the Tax Court’s unyielding enforcement of jurisdictional deadlines, even in the shadow of the COVID-19 pandemic, and highlights the broader tension between taxpayer rights and the IRS’s procedural defenses.

The stakes could not have been higher. The IRS had issued a Notice of Deficiency (NOD) under Section 6212(a), which authorizes the agency to send a deficiency notice via certified or registered mail to the taxpayer’s last known address. Under Section 6213(a), the taxpayer then has 90 days to file a petition with the Tax Court to contest the proposed adjustments. The court’s jurisdiction hinges entirely on whether the petition is filed within that window—a rule the Tax Court has repeatedly described as "jurisdictional," meaning no exceptions are permitted absent extraordinary circumstances.

Lindsey’s case was a textbook example of how unforgiving that rule can be. Despite the pandemic’s widespread disruptions to mail delivery and court operations, the Tax Court held that the 90-day deadline was not tolled. The opinion, written by Judge Jones, leaves no room for ambiguity: "The Court lacks jurisdiction over this case because the petition was filed 710 days after the mailing of the Notice of Deficiency." The decision reaffirms the Tax Court’s role as a gatekeeper of procedural rigor, even when taxpayers face personal or systemic challenges. For practitioners and taxpayers alike, the message is clear: the 90-day rule is absolute, and the Tax Court will not bend to accommodate delays—no matter the circumstances.

The Audit That Never Ended: A Timeline of Missed Deadlines

The IRS’s audit of LaTrese Lindsey’s 2017 and 2018 tax returns began in 2019, when the agency proposed disallowing charitable contribution deductions of $35,700 and $41,070, respectively, and asserting accuracy-related penalties under Section 6662—a provision that imposes a 20% penalty on underpayments attributable to negligence, disregard of rules, or substantial understatement of income tax. The proposed adjustments totaled $8,163 in tax for 2017 and $7,935 for 2018, with additional penalties of $1,633 and $1,587, respectively. Lindsey, who resided in Illinois, timely filed a protest with the IRS’s Independent Office of Appeals, triggering a procedural limbo that stretched for years.

On February 14, 2020, Appeals Officer Michele Penry was assigned to Lindsey’s case from the IRS’s Indianapolis office. By March 2020, COVID-19 had shuttered the Indianapolis office, halting normal operations. The disruption was severe enough that the office remained closed until at least June 2020 and operated in a limited capacity through July. On May 28, 2020, Penry prepared a draft Notice of Deficiency (NOD)—the 90-day letter required under Section 6212(a), which authorizes the IRS to send a deficiency notice to taxpayers via certified mail—and routed it to a tax computation specialist for finalization. The specialist uploaded the draft into the Appeals Centralized Database System (ACDS), from which Penry printed the document and placed it in a case file for transmittal to the IRS Appeals Processing and Support (APS) facility in Detroit, Michigan.

The delays continued. On June 4, 2020, Penry suspended Lindsey’s case due to the pandemic, noting in her ACDS case activity record: “SNOD is ready to be sent once office is open.” The suspension lasted until July 22, 2020, when Penry reactivated the case and prepared Form 5402, Appeals Transmittal and Case Memo, a required document for closing an appeal. In the form, Penry concluded that the adjustments proposed in the October 2019 Letter 950—including the disallowed deductions and penalties—should be sustained. She also marked the form to indicate that a Statutory Notice of Deficiency needed to be issued, a procedural step that triggers the 90-day petition window for taxpayers. The next day, July 23, 2020, Penry released Lindsey’s case file to the Detroit APS facility, where it landed on the desk of LaTrese Lindsey (no relation), a tax examining technician tasked with mailing NODs.

Lindsey’s case took a bureaucratic turn in Detroit. The APS facility, operating under Internal Revenue Manual (IRM) 8.20.6.8.4(1) (Sep. 10, 2018), is responsible for mailing deficiency notices to taxpayers. LaTrese Lindsey, who had mailed hundreds of NODs during her tenure, recalled the case specifically because the taxpayer shared her last name. She prepared the mailing using USPS Form 3877, Firm Mailing Book for Accountable Mail, and USPS Form 3800, Certified Mail Receipt, the standard procedure for sending NODs. On August 10, 2020, she processed the mailing, making a contemporaneous entry in ACDS indicating that the NOD for Lindsey’s 2017 and 2018 tax years had been sent. The entry automatically generated a notification in Penry’s case activity record, confirming that the notice had been processed.

The mailing, however, never reached its destination. A Product Tracking and Reporting (PTR) report from the USPS shows that the envelope addressed to Lindsey was received by the USPS processing center in Pontiac, Michigan, on August 10, 2020, but was never delivered. Instead, it remained in transit until February 3, 2021, when it was returned to the IRS’s P.O. Box 330500 in Detroit—a designated address for Freedom of Information Act (FOIA) requests under 26 C.F.R. § 601.702(h)(2). Neither Penry nor LaTrese Lindsey were ever informed of the undelivered mailing, and the record contains no evidence that a returned copy of the NOD was ever provided to Lindsey.

Undeterred by the failed delivery, the IRS moved forward with the assessment. On June 14, 2021—nearly 10 months after the undelivered NOD was mailed—the agency assessed the $16,098 in tax ($8,163 for 2017 and $7,935 for 2018) plus $3,220 in accuracy-related penalties ($1,633 and $1,587, respectively). Lindsey, unaware of the assessment, filed her petition with the Tax Court on October 20, 2022, more than two years after the August 10, 2020, mailing date. The delay stretched the procedural timeline to 710 days—far beyond the 90-day window prescribed by Section 6213(a), which grants taxpayers 90 days (or 150 days if addressed outside the U.S.) to file a petition after the NOD is mailed. The case, now docketed as Lindsey v. Commissioner, would force the Tax Court to confront whether the IRS’s procedural missteps could excuse Lindsey’s late filing.

Clash of Arguments: Did the IRS Mail the Notice?

The stakes in Lindsey v. Commissioner hinge on a single procedural question: whether the IRS successfully mailed a valid Notice of Deficiency (NOD) to LaTrese Lindsey on August 10, 2020. The Tax Court’s resolution of this dispute would determine whether it even had jurisdiction to hear Lindsey’s case—or whether the late-filed petition, arriving 710 days after the alleged mailing, was a non-starter. The IRS and Lindsey advanced diametrically opposed narratives about the mailing, each invoking statutory and procedural rules to support their positions.

Lindsey’s argument centered on the IRS’s failure to prove the NOD was ever properly issued. She contended that the agency did not provide a dated copy of the NOD, nor did it demonstrate compliance with the certified mail procedures required under Section 6212(a), which mandates that the IRS send a NOD "by certified mail or registered mail." The absence of a postmark, a USPS employee’s signature, or any official documentation tying the mailing to August 10, 2020, left a critical evidentiary gap, she argued. Lindsey also pointed to the IRS’s failure to follow its own returned-mail procedures, as outlined in 26 C.F.R. § 601.702(h)(2), which requires the agency to document undelivered mail. Since no returned copy of the NOD was ever produced—and no IRS employee testified to its mailing—the petitioner claimed the IRS could not meet its burden of proving the NOD was ever sent.

The IRS, however, presented a far more streamlined case. It asserted that the NOD was properly mailed to Lindsey’s last known address on August 10, 2020, relying on the presumption of proper mailing established in Coleman v. Commissioner, 94 T.C. 82 (1990). The agency pointed to USPS Form 3877, the Firm Mailing Book for Accountable Mail, which listed the mailing on that date. While the form lacked a postmark or USPS employee signature, the IRS argued that this was not dispositive. Instead, it claimed that the cumulative evidence—including the contemporaneous ACDS entry by Appeals tax examining technician LaTrese Lindsey (no relation to the petitioner), the USPS tracking report showing the envelope was addressed to Lindsey’s address, and the IRS’s standard procedure of mailing NODs via certified mail—sufficed to establish the mailing. The IRS further emphasized that the 90-day deadline under Section 6213(a)—which grants taxpayers 90 days to file a petition after the NOD is mailed—was not contingent on the IRS proving the exact moment of mailing, only that it occurred. In the agency’s view, the lack of a postmark or signature was a procedural nicety, not a fatal flaw.

The clash between these arguments laid bare a fundamental tension in deficiency cases: the IRS’s reliance on presumptions versus the taxpayer’s demand for strict compliance with procedural safeguards. Lindsey’s position hinged on the idea that the IRS’s evidentiary gaps were not merely technicalities but substantive failures that undermined the validity of the NOD itself. The IRS, meanwhile, framed the dispute as a classic battle over jurisdiction—where the petitioner’s late filing, not the mailing, was the real issue. The Tax Court would soon have to decide which narrative carried the day.

The Court's Verdict: No Second Chances for Late Petitions

The Tax Court’s decision in Lindsey v. Commissioner, T.C. Memo. 2026-10 (Sept. 10, 2026), delivered a stark warning to taxpayers: the 90-day deadline to petition the Tax Court after receiving a Notice of Deficiency (NOD) is absolute, and the court will not bend procedural rules—even in the face of evidentiary gaps or extraordinary circumstances like the COVID-19 pandemic. The opinion, authored by Judge Lauber, rejected Lindsey’s arguments that the IRS’s procedural missteps justified equitable tolling or an extension of the jurisdictional deadline under § 6213(a), which requires petitions to be filed within 90 days of the NOD’s mailing. The court’s holding hinged on two critical determinations: first, that the IRS had proven the NOD’s existence and proper mailing through cumulative evidence, and second, that Lindsey’s untimely petition deprived the court of jurisdiction regardless of the IRS’s evidentiary shortcomings.

The court’s reasoning unfolded in two tightly reasoned sections, each dissecting the IRS’s burden of proof under § 6212 and § 6213(a). In addressing the NOD’s existence, the court relied on the undated copies of the notice, the testimony of Appeals Officer (AO) Penry, and the Appeals Centralized Database System (ACDS) records to infer that the IRS had indeed created and issued the NOD. The court noted that while the copies were undated and the USPS Form 3877 was incomplete, the IRS’s burden under § 6212 did not require perfection—only sufficient evidence to establish the NOD’s issuance. The court quoted Gregory v. Commissioner, T.C. Memo. 2018-192, to underscore this point: “The Code does not specify the form of the Notice,” and a valid NOD need only “fairly advise the taxpayer that the Commissioner has, in fact, determined a deficiency and specify the year and amount.” Here, the copies identified the tax years (2017 and 2018) and the deficiency amounts, satisfying the minimal requirements of § 7522(a).

The court then turned to the IRS’s burden to prove proper mailing, rejecting Lindsey’s argument that the IRS’s failure to produce a complete USPS Form 3877 or a presumption of mailing under Coleman v. Commissioner, 94 T.C. 82 (1990), doomed its case. Instead, the court held that the IRS had met its burden through “otherwise sufficient evidence,” including the testimony of Tax Examiner (TE) LaTrese and the ACDS records. TE LaTrese testified that she processed the NOD for mailing on August 10, 2020, and the ACDS entries—made contemporaneously and incapable of being backdated—corroborated her account. The court emphasized that the ACDS Case Summary Card (Exhibit 18-R) was admissible under Fed. R. Evid. 803(6) as a record of a regularly conducted activity, despite Lindsey’s objections that it was prepared for litigation. The court found that the underlying ACDS data was kept in the ordinary course of the IRS’s business and that the entries were made contemporaneously with the actions they documented. This cumulative evidence, the court concluded, was enough to establish that the NOD was mailed to Lindsey’s last known address on August 10, 2020.

The court’s strict interpretation of § 6213(a)’s jurisdictional deadline left no room for Lindsey’s arguments that COVID-19-related disruptions or the IRS’s evidentiary gaps warranted equitable tolling. The opinion directly addressed the circuit split on whether equitable tolling applies to the 90-day deadline, noting that the Seventh Circuit’s precedent in Tilden v. Commissioner, 846 F.3d 882 (7th Cir. 2017), binds the Tax Court in this case. In Tilden, the Seventh Circuit held that the 90-day deadline is jurisdictional and not subject to equitable tolling, even when the taxpayer’s delay was caused by incarceration. The Tax Court in Lindsey followed Tilden to the letter, stating: “The 90-day deadline is jurisdictional, and equitable tolling is not available to extend it.” The court rejected Lindsey’s reliance on Organic Cannabis Foundation, LLC v. Commissioner, 962 F.3d 1082 (9th Cir. 2020), which allowed equitable tolling in limited circumstances where the IRS misled the taxpayer, because the Seventh Circuit’s binding precedent foreclosed that argument.

The court’s rejection of equitable tolling was not merely a procedural formality—it underscored the Tax Court’s role as a court of limited jurisdiction, bound by the strictures of § 6213(a). The opinion quoted Frieling v. Commissioner, 81 T.C. 42, 46 (1983), to reinforce this point: “Our jurisdiction depends upon the Commissioner’s issuing a valid notice of deficiency and the taxpayer’s timely filing his petition.” Because Lindsey filed her petition on October 20, 2022—more than 90 days after the NOD’s alleged mailing on August 10, 2020—the court lacked jurisdiction to consider the merits of her case. The court’s holding was unequivocal: “The petition was untimely, and we therefore lack jurisdiction to redetermine the deficiency.”

The implications of Lindsey extend far beyond the individual taxpayer, signaling the Tax Court’s willingness to enforce procedural deadlines with uncompromising rigor. For future taxpayers, the case serves as a cautionary tale: the 90-day deadline is not a suggestion, and the court will not entertain arguments that the IRS’s evidentiary gaps or external circumstances justify an extension. The opinion’s emphasis on cumulative evidence to prove mailing—rather than relying on presumptions—also signals a shift in how the Tax Court may evaluate IRS compliance with § 6212(a) in future cases. Taxpayers challenging an NOD’s validity must now anticipate that the court will scrutinize not just the NOD itself, but the entire administrative record, including ACDS entries and employee testimony, to determine whether the IRS met its burden. For practitioners, Lindsey reinforces the need to file petitions promptly and to challenge any procedural irregularities in the IRS’s handling of a case before the deadline expires. The Tax Court’s message is clear: when it comes to the 90-day rule, there are no second chances.

Evidentiary Battle: Why the ACDS Case Summary Card Mattered

The IRS’s victory in Lindsey v. Commissioner hinged not on the Notice of Deficiency’s validity, but on the admissibility of Exhibit 18-R—the ACDS Case Summary Card—a document the Tax Court admitted over Lindsey’s hearsay objection. The dispute over this single exhibit exposed how IRS internal records, when authenticated under the Federal Rules of Evidence, can become the decisive factor in a deficiency case.

Lindsey’s challenge to Exhibit 18-R was rooted in hearsay. The IRS offered the document as a record of a regularly conducted activity under Federal Rule of Evidence 803(6), which permits the admission of business records if they are made “at or near the time by, or from information transmitted by, a person with knowledge.” Fed. R. Evid. 803(6). Lindsey argued that the ACDS Case Summary Card failed this test because it was not prepared by the IRS employee who entered the data and because the system lacked sufficient safeguards against tampering. She also claimed the entries were not trustworthy, pointing to potential inaccuracies in the Appeals process.

The court rejected Lindsey’s arguments, emphasizing that Rule 803(6) does not require the preparer to be the same person who entered the data, only that the record be made in the regular course of business. The court noted that the ACDS system is designed to capture contemporaneous entries by Appeals officers during case processing, and that the IRS had presented testimony from TE LaTrese, an Appeals Officer, who authenticated the entries as accurate reflections of the Appeals process. The court held:

“Exhibit 18-R is admissible as a record of a regularly conducted activity under Rule 803(6) of the Federal Rules of Evidence. The IRS has shown that the ACDS Case Summary Card was made at or near the time of the Appeals process, by a person with knowledge, and that it was kept in the regular course of business.”

The court further dismissed Lindsey’s trustworthiness concerns, finding that the ACDS system’s automated logging and employee testimony provided sufficient indicia of reliability. The IRS had not only produced the card but also corroborated its contents with sworn testimony, shifting the burden to Lindsey to disprove its accuracy—a burden she failed to meet.

This evidentiary ruling underscored a critical lesson for practitioners: the Tax Court will scrutinize not just the Notice of Deficiency, but the entire administrative record, including IRS internal systems like ACDS. When the IRS authenticates its records through employee testimony and system integrity, hearsay objections are unlikely to prevail. For taxpayers challenging an IRS deficiency, this means the evidentiary battlefield extends beyond the NOD itself—it now includes the IRS’s own case management records.

The 90-Day Rule: Why COVID-19 Couldn't Save Lindsey's Petition

The Tax Court’s ruling in Lindsey v. Commissioner (T.C. Memo. 2026-15) delivered a blunt reminder to taxpayers: the 90-day deadline to petition the Tax Court after receiving a Notice of Deficiency is not just a procedural formality—it is a jurisdictional gatekeeper, immune to pandemic-era disruptions or claims of equitable tolling. The court’s analysis hinged on the unyielding nature of § 6213(a), which the Seventh Circuit has long treated as a jurisdictional bar, and the IRS’s strict compliance with its own mailing protocols, even amid COVID-19’s operational chaos.

The court’s reasoning crystallized a longstanding precedent: the 90-day deadline under § 6213(a) is not merely a deadline at all—it is a jurisdictional prerequisite to the Tax Court’s authority to hear a deficiency case. The Seventh Circuit’s 2017 decision in Tilden v. Commissioner, 846 F.3d 882, 886–87 (7th Cir. 2017), rev’g and remanding T.C. Memo. 2015-188, remains the controlling authority here, and the Tax Court had no discretion to waive it. As the court noted, “the statutory filing deadline under section 6213 is jurisdictional,” and “relief contemplated by equitable tolling is not available.” The opinion did not mince words: the Tax Court’s jurisdiction over Lindsey’s case evaporated the moment her petition arrived 710 days after the deadline.

Lindsey’s argument that COVID-19 disrupted her ability to file—whether through court closures, IRS delays, or personal hardship—collided with the court’s uncompromising stance on the deadline’s nature. The Tax Court acknowledged the pandemic’s widespread impact but refused to carve out an exception, citing the Supreme Court’s 2022 decision in Boechler, P.C. v. Commissioner, 142 S. Ct. 1493, which held that while the 90-day deadline may not be jurisdictional in all circuits, it remains a mandatory and strictly enforced rule. The court emphasized that even if equitable tolling were theoretically available in other circuits—such as the Ninth Circuit’s limited allowance in Organic Cannabis Found., LLC v. Commissioner, 962 F.3d 1082, 1092 (9th Cir. 2020)—the Seventh Circuit’s precedent foreclosed any such relief. The opinion quoted Tilden directly: “the statutory filing deadline under section 6213 is jurisdictional,” leaving no room for Lindsey’s COVID-19-related pleas.

The court’s deference to the IRS’s mailing procedures further underscored its unwillingness to bend the rules. The IRS had authenticated its records through employee testimony and the Appeals Centralized Database System (ACDS), a move the court deemed sufficient to establish that the Notice of Deficiency was mailed to Lindsey’s last known address on August 10, 2020. The last day to file a timely petition—November 9, 2020—was calculated by excluding weekends and legal holidays, as required by § 6213(a). Lindsey’s petition, filed on October 20, 2022, arrived nearly two years late, and the court had no choice but to dismiss the case for lack of jurisdiction.

The court’s analysis also highlighted a growing circuit split on the issue, though it did not alter the outcome. While the Ninth Circuit’s Organic Cannabis decision and the Eighth Circuit’s Maniktala v. Commissioner, 186 F.4th 548, 554–55 (8th Cir. 2026), have entertained limited equitable tolling, the Seventh Circuit’s Tilden precedent—and the Tax Court’s adherence to it—remains the dominant force in cases appealable to that circuit. The court cited Seekamp v. Commissioner, No. 25-1375, 2026 WL 2199201, at *2 (9th Cir. July 30, 2026), which reaffirmed Organic Cannabis, but noted that it was irrelevant here. The First Circuit’s Kyick Holdings, LLC v. Commissioner, No. 25-1429, 2026 WL 2389513, at *15 (1st Cir. Aug. 17, 2026), which held the deadline was nonjurisdictional but not subject to equitable tolling, was similarly distinguishable. The Tax Court’s hands were tied by the jurisdictional nature of the deadline as defined by the controlling circuit.

For taxpayers facing similar circumstances, the court left one sliver of hope: alternative remedies. The opinion noted that Lindsey could still pursue a refund claim under § 6511 if she believed the IRS had erroneously assessed the deficiency. But the Tax Court’s doors were shut. The message was clear: the 90-day rule brooks no exceptions, pandemic or otherwise. The IRS’s mailing procedures, once authenticated, are nearly impossible to overcome, and the Tax Court will not assume the role of a safety net for late filers. The court’s jurisdictional gatekeeping was absolute, and Lindsey’s petition was the casualty.

What This Means for Taxpayers: Three Lessons from Lindsey

The Tax Court’s dismissal of Lindsey’s petition in Lindsey v. Commissioner, T.C. Memo. 2026-XX (Sept. 24, 2026) was not an outlier—it was a textbook example of how the Tax Court enforces the 90-day jurisdictional deadline under § 6213(a). The court held that the deadline is “absolute,” rejecting arguments that COVID-19 disruptions or undelivered mail could excuse a late filing. The opinion underscored that the Tax Court’s jurisdiction under § 6212(a) hinges entirely on the IRS’s ability to prove proper mailing of the Notice of Deficiency (NOD) to the taxpayer’s last known address. For taxpayers and practitioners, the case delivers three hard lessons that transcend Lindsey’s individual circumstances.

First, the 90-day rule brooks no exceptions. The court made clear that the deadline is jurisdictional, quoting the statute verbatim: “We likewise have no authority to extend the period prescribed for doing so by section 6213(a).” The IRS’s mailing procedures, once authenticated through USPS Form 3877 or other corroborating evidence, are nearly impossible to overcome. Even the pandemic’s disruption to mail delivery and court operations—factors that had swayed some courts in earlier cases—failed to sway the Tax Court. The opinion cited Boechler, P.C. v. Commissioner, 142 S. Ct. 1493 (2022), which held that the 90-day deadline is mandatory, though not strictly jurisdictional, but the Tax Court treated it as dispositive. Practitioners should treat the 90-day window as a hard stop: file early, file often, and assume no grace period exists.

Second, tracking IRS correspondence is non-negotiable. The IRS’s burden of proof for mailing the NOD is substantial but not insurmountable. The court accepted the IRS’s evidence—likely a Form 3877 and ACDS case summary card—as sufficient to establish mailing to Lindsey’s last known address. This underscores the importance of maintaining meticulous records of address changes, certified mail receipts, and any IRS correspondence. Taxpayers who fail to update their address with the IRS via Form 8822 risk having their NOD sent to an outdated address, rendering it invalid under § 6212(b)(1). The court’s reliance on the ACDS records highlights how critical these internal IRS documents are in litigation. Practitioners should demand these records in discovery and use them to challenge the IRS’s diligence in address verification.

Third, forum shopping matters more than ever. The court’s opinion implicitly acknowledged the circuit split on equitable tolling, noting that Tilden v. Commissioner, 846 F.3d 882 (7th Cir. 2017), remains binding in the Seventh Circuit. While the Tax Court did not explicitly endorse equitable tolling, the reference to the split signals that taxpayers in circuits like the Ninth—where Organic Cannabis Foundation, LLC v. Commissioner, 962 F.3d 1082 (9th Cir. 2020), allows limited exceptions—may have slightly more leeway. For taxpayers in the Seventh Circuit or others with strict interpretations, the message is clear: the Tax Court will not serve as a safety net. This jurisdictional gatekeeping forces taxpayers to choose their forum carefully, especially when deadlines are tight.

The forward-looking implication is equally stark. Congress could amend § 6213(a) to clarify whether equitable tolling applies, but until then, taxpayers must act with urgency. The Tax Court’s dismissal in Lindsey was not an anomaly—it was a warning. The IRS’s mailing procedures, once authenticated, are nearly impossible to overcome, and the Tax Court will not assume the role of a safety net for late filers. The message is clear: the 90-day rule brooks no exceptions, pandemic or otherwise. Taxpayers who receive a Notice of Deficiency must move quickly, verify their address, and file their petition within the statutory window—or risk forfeiting their day in court.
