Summer H. El Deeb v. Commissioner of Internal Revenue: Unreported Wage Income and Jurisdictional Limits on Estimated Tax Payments

The $5,518 Mistake: How Unreported Wages and a Missing $3,000 Payment Led to a Tax Court Showdown

The stakes could not have been clearer when Judge Jones of the United States Tax Court issued T.C. Memo. 2026-101 on September 29, 2026. At issue was a $5,518 deficiency in federal income tax for taxable year 2021, a sum that exposed Summer H. El Deeb to both a deficiency and an accuracy-related penalty. But the real battle lines were drawn over a $3,000 claim—one the court ultimately ruled it could not touch. In a rare display of jurisdictional clarity, the Tax Court asserted its power under § 6211(b)(1) to exclude estimated tax payments from deficiency computations, reinforcing the boundaries of its authority in deficiency proceedings. The court held that while it could sustain the IRS’s determination on unreported wages, it lacked jurisdiction to consider the merits of the $3,000 estimated tax payment or carryover claim. This ruling underscores the Tax Court’s willingness to exercise judicial power not only over tax liabilities but also over the scope of its own jurisdiction—a move that will reverberate in future disputes involving estimated tax payments and carryovers.

The Taxpayer’s Tale: A Chronology of Unreported Income and Amended Returns

The dispute in El Deeb v. Commissioner began with a routine tax filing that spiraled into a jurisdictional and substantive battle over unreported wages and disputed estimated tax payments. The chronology of Ms. El Deeb’s interactions with the IRS reveals a series of missteps, automated system errors, and procedural roadblocks that ultimately led to a deficiency notice and a Tax Court petition.

Ms. El Deeb’s tax saga commenced on March 6, 2022, when she filed her 2021 Form 1040, reporting taxable wages of $28,230 and total tax of $1,381. The return, filed electronically, was processed by the IRS on April 4, 2022, reflecting an overpayment of $10,405 based on her reported payments of $11,786. These payments included $935 in withholding, $3,000 in claimed child tax credit, $3,694 in earned income tax credit (EITC), $1,157 in child and dependent care credit, and $3,000 attributed to “2021 estimated tax payments and amount applied from 2020 return.” The IRS, however, did not share Ms. El Deeb’s assessment of her payment history. On April 11, 2022, the agency issued a refund of only $7,405, citing a lack of records for the $3,000 estimated tax payment or any carryover credit from 2020. The IRS’s Form 4340, Certificate of Assessments, Payments, and Other Specified Matters, confirmed the discrepancy, showing refunds totaling $7,200—including $1,400 and $2,800 for the 2021 Recovery Rebate Credit under the American Rescue Plan Act of 2021 (ARPA), and $500 monthly advance child tax credit payments from July to December 2021.

Undeterred by the IRS’s refund adjustment, Ms. El Deeb sought to correct her return by filing a Form 1040-X, Amended U.S. Individual Income Tax Return, on May 26, 2022. The amended return asserted a $16,027 increase to her adjusted gross income (AGI), raising her total tax to $3,254 and claiming an additional $520 in withholding. She also maintained her position that the $3,000 estimated tax payment or prior-year credit should apply to her 2021 liability. The IRS, however, never processed the amended return. The agency’s inaction left Ms. El Deeb in limbo, her claims unaddressed and her tax liability unresolved.

The IRS’s automated systems took over on January 2, 2024, when its Automated Underreporter (AUR) program flagged Ms. El Deeb’s 2021 return. The program identified $16,026 in unreported wage income from Aerotek, Inc., along with $519 in corresponding withholding credits, $800 in unreported income from the Research Foundation for SUNY, and a computational adjustment to her EITC. Based on these adjustments, the IRS issued a Notice of Deficiency on January 2, 2024, determining a deficiency in income tax of $5,518 and a $1,000 accuracy-related penalty under Section 6662(a) for a substantial understatement of income tax. The deficiency notice did not account for the $3,000 estimated tax payment or any carryover credit, as these items were not part of the deficiency computation under Section 6211(b)(1).

Ms. El Deeb’s attempts to resolve the matter continued even after the deficiency notice. On March 21, 2024, the IRS issued Letter 2626C, informing her that her first amended return could not be processed because it did not address the $800 of other income reported by the Research Foundation for SUNY. Undeterred, she submitted a second Form 1040-X on April 30, 2024, but the IRS’s systems remained unresponsive. The agency’s refusal to process the amended returns, combined with the deficiency notice, left Ms. El Deeb with no choice but to petition the Tax Court on March 20, 2024, challenging the IRS’s determinations. The case, now before the court, hinges on whether the IRS’s adjustments to unreported wages are valid—and whether the Tax Court has the jurisdiction to consider the merits of the $3,000 estimated tax payment or carryover claim.

The Dispute: Petitioner’s Claims vs. IRS’s Determinations

The Tax Court case El Deeb v. Commissioner crystallizes a dispute over $5,518 in tax, penalties, and a $3,000 estimated tax payment that the IRS insists never existed. At its core, the case turns on whether Ms. El Deeb’s unreported wages from Aerotek and her entitlement to refundable credits can withstand the IRS’s adjustments—or whether her claims for a missing $3,000 payment and additional credits hold legal weight.

Ms. El Deeb’s arguments hinge on two pillars. First, she asserts that the IRS failed to credit her with a $3,000 estimated tax payment for 2021 or a carryover from her 2020 return, despite her repeated attempts to amend her 2021 return to reflect this. Her first amended return, filed on May 26, 2022, claimed a $10,405 overpayment, of which only $7,405 was refunded by the IRS. The agency’s refusal to process the remaining $3,000—either as an estimated payment or a prior-year carryover—left her with a $3,000 shortfall in her claimed overpayment. Second, she argues that she is entitled to additional refundable credits, including a $3,380 computational decrease to her Earned Income Tax Credit (EITC) on her first amended return and a $3,549 reduction on her second amended return, filed April 30, 2024. These credits, she contends, were improperly denied or undercalculated by the IRS.

The IRS, however, rejected Ms. El Deeb’s claims with a series of adjustments that paint a different picture of her 2021 tax liability. The agency determined that Ms. El Deeb failed to report $16,027 in wage income from Aerotek, Inc., a staffing agency, on her original 2021 Form 1040. This unreported income formed the backbone of the IRS’s deficiency calculation, which also included a $519 withholding credit adjustment for the wages. Additionally, the IRS initially included $800 of unreported income from the Research Foundation for SUNY, though this amount was later conceded by the agency. The IRS also proposed a section 6662(a) accuracy-related penalty for a substantial understatement of income tax, which it later conceded as well.

Before trial, the parties engaged in a series of stipulations that narrowed the battlefield. They agreed that Ms. El Deeb did not report the $16,027 in wages from Aerotek on her original 2021 return, a fact that underpins the IRS’s deficiency determination. They also stipulated that she is entitled to a $520 withholding credit related to her Aerotek wages and that the $800 payment from SUNY is not taxable. Further, the parties agreed that Ms. El Deeb is entitled to a $6,000 refundable child tax credit for 2021, of which $3,000 was paid as advance child tax credit payments, and a $2,830 refundable child and dependent care credit. These stipulations reflect the IRS’s concessions on the SUNY income and the accuracy-related penalty, as well as Ms. El Deeb’s entitlement to certain credits.

Yet, despite these concessions, the $3,000 estimated tax payment or carryover remains unresolved. The IRS maintains that it has no record of receiving the payment or any prior-year credit to apply to 2021, a position that Ms. El Deeb disputes. The agency’s refusal to process her amended returns—first on May 26, 2022, and again on April 30, 2024—fueled her decision to petition the Tax Court, where she now seeks to compel the IRS to recognize the $3,000 as either an estimated payment or a carryover. The stakes are clear: if the Tax Court rules in her favor, the $3,000 could offset the deficiency or even generate a refund. If not, the IRS’s deficiency determination stands, leaving Ms. El Deeb liable for the $5,518 tax and penalties.

The Court’s Reasoning: Why the IRS Prevailed on Unreported Wages

The Tax Court’s analysis hinged on the undisputed fact that Ms. El Deeb received $16,027 in taxable wages from Aerotek in 2021—and failed to report them on her Form 1040. The court’s holding rested on two foundational principles: the broad scope of gross income under § 61(a) and the burden-shifting framework of Rule 142(a).

Gross Income Under § 61(a): The Legal Backdrop The court began by invoking § 61(a), which defines gross income as “all income from whatever source derived,” including “compensation for services.” The court cited Commissioner v. Glenshaw Glass Co., 348 U.S. 426, 429–31 (1955), for the proposition that this definition encompasses all undeniable accessions to wealth over which the taxpayer has dominion. Wages—whether paid in cash, by check, or through third-party payers like Aerotek—fall squarely within this definition. The court emphasized that § 61(a)(1) explicitly includes “compensation for services,” leaving no room for argument that unreported wages escape taxation unless expressly excluded by another Code provision.

Burden of Proof and the Stipulation’s Effect The court then turned to the burden of proof, a critical juncture where Ms. El Deeb’s case unraveled. Under Rule 142(a), the IRS’s deficiency determination is presumed correct, and the taxpayer bears the burden of proving it erroneous. The court noted that this presumption applies unless the taxpayer can shift the burden under § 7491(a), which requires satisfying specific record-keeping and substantiation requirements. Ms. El Deeb did not meet those requirements.

The decisive moment came when the parties stipulated to the $16,027 in Aerotek wages. The court held that this stipulation established a “sufficient evidentiary basis” to connect Ms. El Deeb with the unreported income. Citing Walquist v. Commissioner, 152 T.C. 61, 67 (2019), the court explained that once the IRS makes a minimal evidentiary showing—here, through the stipulation—the burden shifts to the taxpayer to disprove the deficiency. Ms. El Deeb presented no evidence to rebut the taxability of the wages, no offsets or deductions, and no argument that the income was otherwise excluded. The court quoted the stipulation itself as dispositive: “Ms. El Deeb stipulated that she received $16,027 of taxable wages from Aerotek, which she did not report on her Form 1040 for taxable year 2021.”

Why the IRS Prevailed The court sustained the IRS’s determination because Ms. El Deeb failed to carry her burden after the stipulation shifted it. The opinion underscored that the IRS’s reliance on third-party wage reports—here, Aerotek’s Form W-2—was sufficient under § 6201(d), which permits the Commissioner to rely on such reports unless the taxpayer raises a reasonable dispute about their accuracy. Ms. El Deeb did not dispute the Aerotek wages’ accuracy or taxability. Without evidence to the contrary, the court had no choice but to uphold the deficiency.

The court’s reasoning reflects a muscular exercise of judicial power over unreported income cases. By deferring to the stipulation and refusing to entertain unsupported arguments, the Tax Court reinforced its role as the final arbiter of factual disputes in deficiency proceedings. The opinion leaves no ambiguity: when a taxpayer stipulates to unreported wages, the IRS’s deficiency determination stands unless the taxpayer can present admissible evidence to the contrary. The Tax Court’s authority here was not merely declaratory—it was dispositive.

Jurisdictional Limits: Why the Court Couldn’t Rule on the $3,000 Payment

The Tax Court’s authority is not boundless—it operates within strict jurisdictional limits defined by statute. In El Deeb v. Commissioner, the court made this clear when it declined to rule on Ms. El Deeb’s claim that she had made a $3,000 estimated tax payment for 2021 or had $3,000 applied from her 2020 return. The court held that it lacked jurisdiction to consider adjustments to payment credits excluded from deficiency computations under § 6211(b)(1), which defines a deficiency as the amount by which the tax imposed exceeds the tax shown on the return without regard to payments on account of estimated tax.

The court’s reasoning hinged on the plain language of § 6211(b)(1), which explicitly excludes estimated tax payments from deficiency computations. As the opinion noted, “A deficiency is determined ‘without regard to payments on account of estimated tax.’” The exclusion extends to overpayments from a prior year credited against estimated tax for the current year, as seen in §§ 6402(b) and 6513(d) and Treasury Regulation § 301.6402-3(a)(5). The court cited Vento v. Commissioner, 152 T.C. 1, 32 (2019) (Halpern, J., concurring in the result), supplementing 147 T.C. 198 (2016), aff’d, 836 F. App’x 607 (9th Cir. 2021), for the proposition that estimated tax payments are not part of the deficiency calculation.

The court further emphasized that its jurisdiction is limited to redetermining the deficiency for the taxable year in question. Under § 6214(b), the Tax Court may only consider facts relating to other taxable years if necessary to redetermine the deficiency for the year before it. However, the court lacks jurisdiction to determine whether a taxpayer overpaid tax for a different year. In this case, Ms. El Deeb’s claim that the $3,000 represented an estimated tax payment or a prior-year overpayment applied to 2021 was outside the scope of the deficiency proceeding. The court held, “Whether the reported $3,000 represents an estimated tax payment for taxable year 2021 or an amount applied from taxable year 2020, the amount is excluded from the computation of the deficiency.”

The court’s exercise of jurisdictional power was not merely declaratory—it was dispositive. Citing Bregin v. Commissioner, 74 T.C. 1097, 1102, 1104–05 (1980), the court reiterated that an adjustment to a payment credit excluded from the deficiency computation does not give rise to a deficiency within the meaning of § 6211. The court also relied on Pope v. Commissioner, T.C. Memo. 2020-62, at *6–7, and Forrest v. Commissioner, T.C. Memo. 2011-4, 2011 WL 13626, at *3, for the principle that the Tax Court lacks jurisdiction over withholding-credit issues when they do not factor into the deficiency determination. The court concluded, “Accordingly, we lack jurisdiction to redetermine whether Ms. El Deeb made the claimed $3,000 estimated tax payment or had a $3,000 overpayment from taxable year 2020 applied toward her estimated tax for taxable year 2021.”

This jurisdictional boundary underscores the Tax Court’s role as a forum for resolving deficiencies—not for adjudicating disputes over payment credits or prior-year overpayments. The court’s refusal to entertain Ms. El Deeb’s claim was not a substantive ruling on the merits but a strict adherence to the limits of its statutory authority. By declining to rule on the $3,000 payment, the court reinforced the principle that deficiency proceedings are confined to the tax years and issues presented in the notice of deficiency. The IRS’s deficiency determination stood, and the taxpayer’s jurisdictional challenge fell outside the court’s power to grant relief.

Credits and Adjustments: The Parties’ Stipulations and Their Impact

The parties’ stipulations in El Deeb v. Commissioner (T.C. Memo. 2026-11, filed Sept. 15, 2026) resolved several key credit issues, narrowing the dispute to the computational impact of unreported wages on the Earned Income Tax Credit (EITC). The IRS conceded two refundable credits in full, while the computational adjustment to the EITC—driven by the unreported wages—became the central unresolved matter.

The parties orally stipulated and agreed in writing that Ms. El Deeb was entitled to a $6,000 refundable child tax credit for tax year 2021, of which $3,000 had been paid as advance child tax credit payments under § 24(a). The court noted this concession in its findings, emphasizing that the advance payments were properly accounted for in the stipulated credit amount. The agreement also included a $2,830 refundable child and dependent care credit, a $1,673 increase from the $1,157 originally claimed on her Form 1040 under § 21(a). These stipulations removed any dispute over the eligibility or calculation of these two credits, leaving only the EITC subject to adjustment.

The EITC, governed by § 32(a)(1), presented a more complex scenario. The IRS did not disallow the EITC in the Notice of Deficiency but instead made computational adjustments to the credit amount based on the unreported wages. The court explained that the EITC is a refundable credit calculated as a percentage of earned income, with the percentage and maximum credit varying by the number of qualifying children. Because the unreported wages increased Ms. El Deeb’s earned income, the computational adjustment to the EITC was necessary to reflect the correct credit amount under § 32(b). The court cited the IRS’s adjustment as consistent with the statute, noting that the EITC’s structure requires recalculation whenever earned income changes.

The stipulations also clarified that the $3,000 advance child tax credit payment was not at issue in the EITC computation, as the parties had agreed it was properly applied to the child tax credit. The court’s opinion underscored that the stipulations streamlined the case, allowing the focus to remain on the computational adjustment to the EITC rather than on eligibility disputes. The IRS’s concession on the child tax credit and child and dependent care credit demonstrated its willingness to resolve straightforward credit issues, while the EITC adjustment remained the sole point of contention.

The court’s reliance on the stipulations highlighted the efficiency of Rule 91(e) stipulations in Tax Court proceedings. By agreeing to the credit amounts, the parties avoided protracted litigation over issues that were not in dispute, allowing the court to concentrate on the computational impact of the unreported wages. The stipulations also ensured that the taxpayer received the full benefit of the credits to which she was entitled, absent the EITC adjustment. The IRS’s computational adjustment to the EITC, driven by the unreported wages, stood as the only unresolved issue, reinforcing the court’s role in resolving disputes based on the evidence and stipulations presented.

What This Means for Taxpayers: Lessons from El Deeb v. Commissioner

The Tax Court’s ruling in El Deeb v. Commissioner delivers a sharp reminder to taxpayers about the unforgiving mechanics of wage reporting and the strict jurisdictional boundaries of the Tax Court. The case underscores that all wage income—whether reported on a W-2, 1099-NEC, or paid in cash—must be included in gross income under § 61(a)(1), which defines compensation for services as taxable income unless excluded by statute. The court’s holding that the taxpayer failed to report $5,518 in Aerotek wages—triggering a recalculation of her Earned Income Tax Credit (EITC)—is a cautionary tale for anyone tempted to underreport income, even modest amounts. The EITC, which was made refundable for 2021 under the American Rescue Plan Act § 9631(a), is particularly sensitive to unreported earnings; the court’s adjustment to the EITC demonstrates how a single omission can ripple into a larger tax liability.

Crucially, the Tax Court’s decision also clarifies a jurisdictional trap that ensnares many taxpayers: the court lacks authority to adjudicate disputes over estimated tax payments or amounts applied from prior-year returns under § 6211(b)(1). The IRS’s determination that the taxpayer’s $3,000 in estimated tax payments or prior-year application did not offset the deficiency was final because the Tax Court’s jurisdiction is confined to the deficiency notice issued. As the court explicitly held, “the Court lacks jurisdiction to consider the claimed $3,000 ‘estimated tax payments [or] amount applied from 2020 return.’” This means taxpayers cannot rely on the Tax Court to resolve disputes about prepayments; such issues must be addressed through refund claims under § 7422 or by paying the deficiency and suing for recovery in district court or the Court of Federal Claims. The IRS’s separate assessment of underpayment penalties under § 6654 further underscores that estimated tax disputes are a distinct enforcement mechanism, not a defense to a deficiency.

For taxpayers claiming refundable credits like the EITC, El Deeb highlights the need for meticulous recordkeeping and full disclosure. The court’s willingness to adjust the EITC based on unreported wages—despite the parties’ stipulation that the taxpayer was entitled to other credits—shows that the IRS and Tax Court will enforce the statutory requirements of § 32 without leniency. Taxpayers should treat the EITC as a privilege tied to precise reporting, not an entitlement that can be claimed without strict compliance. The IRS’s use of automated systems like the Automated Underreporter (AUR) Program to flag mismatches between wage income and tax returns makes this compliance even more critical; a single unreported dollar can trigger a deficiency notice, penalties, and a recalculation of credits.

Looking ahead, El Deeb serves as a boundary marker for the Tax Court’s authority. The decision reaffirms that the court’s role is to adjudicate deficiencies based on the evidence and stipulations before it, not to rewrite the IRS’s computational adjustments or expand its jurisdiction beyond the notice of deficiency. Taxpayers and practitioners must recognize that the Tax Court is not a forum for collateral disputes—such as estimated tax payment offsets—but a specialized tribunal for resolving deficiencies. This case clarifies that when the IRS issues a deficiency notice, the taxpayer’s window to challenge the underlying tax liability is narrow, and the scope of that challenge is strictly defined. The lesson is clear: accurate wage reporting, diligent recordkeeping, and prompt action in response to IRS notices are the best defenses against the kind of computational adjustments that led to the taxpayer’s $5,518 liability in El Deeb.
