Tax Court Denies $1,400 Recovery Rebate Credit Due to ITIN Use

The $1,400 Credit at Stake: ITIN vs. SSN Showdown

The Tax Court’s September 3, 2026 ruling in Merida Ortiz v. Commissioner (Docket No. 13093-25) delivered a stark message to millions of ITIN filers: the $1,400 2021 Economic Recovery Rebate Credit under Section 6428B is off-limits to anyone without a Social Security Number. The court granted the IRS’s Motion for Judgment on the Pleadings, denying the petitioner’s claim after finding his use of an ITIN on his 2021 return rendered him statutorily ineligible for the credit. This decision underscores the Tax Court’s authority under Rule 120(a) to resolve disputes based solely on the pleadings when no material facts are in dispute—a power the court exercised decisively here. For taxpayers relying on ITINs, the ruling is a cautionary tale: the credit’s eligibility hinges not on need, but on the rigid identification requirements Congress embedded in the statute. The stakes extend beyond this single case. The IRS issued 1.1 million notices of deficiency in 2025 targeting improper claims of the 2021 credit, with ITIN-related denials comprising a significant share. The Tax Court’s endorsement of the IRS’s position signals a hardening stance that will shape future refund claims and audit defenses for ITIN holders seeking to navigate the post-pandemic tax landscape.

The Facts: A Chronology of the Disputed Credit

Petitioner first obtained an Individual Taxpayer Identification Number (ITIN) from the IRS at an unspecified date before 2021. The ITIN was issued under the authority of Section 6109 and Treas. Reg. § 301.6109-1(d), which permits the IRS to assign identification numbers to individuals who are not eligible for a Social Security Number (SSN) but are required to file a U.S. tax return. The ITIN served as the sole tax identification number for petitioner in all subsequent filings.

On or about April 15, 2022, petitioner filed his federal income tax return for taxable year 2021. The return was submitted using Form 1040 and included the previously obtained ITIN in the designated field for taxpayer identification. On Line 30 of the return, petitioner claimed the 2021 Economic Recovery Rebate Credit (ERRC) in the amount of $1,400, asserting eligibility under Section 6428B. The credit was claimed as a refundable tax credit pursuant to the American Rescue Plan Act of 2021 (ARPA), which established the ERRC as a one-time payment for eligible individuals.

The IRS processed the return and, on an unspecified date in 2023, issued a Statutory Notice of Deficiency (SNOD) to petitioner. The SNOD disallowed the claimed $1,400 credit in full, citing petitioner’s failure to provide a valid identification number as required by Section 6428B(d). The notice stated that the credit was denied because petitioner’s ITIN did not satisfy the statutory requirement for a valid taxpayer identification number under the 2021 ERRC provisions.

Petitioner, disagreeing with the IRS determination, filed a Petition with the United States Tax Court on or about June 1, 2023. The petition challenged the disallowance of the $1,400 credit and sought a redetermination of the deficiency. The matter was subsequently placed on the court’s docket and assigned to a judge for review. The IRS filed a Motion for Judgment on the Pleadings under Tax Court Rule 120(a), prompting the court to examine the pleadings and motion papers to determine whether judgment could be entered without a full trial.

The Dispute: ITIN as Valid ID vs. SSN Requirement

The core of the dispute hinges on whether an Individual Taxpayer Identification Number (ITIN) satisfies the statutory requirement for a "valid identification number" under section 6428B(e)(2)(D)(i), which governs eligibility for the 2021 economic recovery rebate credit. The IRS argues that only a Social Security Number (SSN) qualifies as a valid identification number, while the petitioner contends that his ITIN should suffice. This disagreement centers on the interpretation of section 6428B(e)(2)(D)(i), which defines a valid identification number as "a social security number issued to an individual by the Social Security Administration on or before the due date for filing the return for the taxable year."

The IRS further bolsters its position by relying on Treas. Reg. § 301.6109-1(d), which explicitly distinguishes ITINs from SSNs. The regulation states that an ITIN is "a taxpayer identifying number issued to an alien individual by the Internal Revenue Service, upon application, for use in connection with filing requirements under [title 26]," and clarifies that "the term IRS individual taxpayer identification number does not refer to a social security number." The regulation also specifies that individuals who have or are entitled to an SSN will not be issued an ITIN, reinforcing the IRS’s argument that the two identification systems serve distinct purposes. The IRS asserts that the plain language of section 6428B(e)(2)(D)(i) and the regulatory framework under Treas. Reg. § 301.6109-1(d) leave no room for ITINs to qualify as valid identification numbers for purposes of the 2021 economic recovery rebate credit.

The petitioner, however, disputes this interpretation, arguing that the term "valid identification number" in section 6428B(e)(2)(D)(i) is not explicitly limited to SSNs and that an ITIN should be considered valid for tax filing purposes. The petitioner emphasizes that an ITIN is a taxpayer identification number issued by the IRS, and thus meets the general requirement of providing a valid identification number on the return. The petitioner’s position relies on the broader definition of a taxpayer identification number under section 6109, which includes ITINs, and argues that the statute does not expressly exclude ITINs from qualifying as valid identification numbers for the credit. The petitioner further contends that the IRS’s reliance on Treas. Reg. § 301.6109-1(d) to differentiate ITINs from SSNs is misplaced, as the regulation pertains to general taxpayer identification requirements rather than the specific eligibility criteria for the 2021 economic recovery rebate credit. The petitioner’s argument thus frames the dispute as a question of whether the IRS has the authority to impose additional restrictions beyond those explicitly stated in the statute.

The Court's Analysis: Legislative Grace and Strict Compliance

The Tax Court’s analysis in Ivan Merida Ortiz v. Commissioner, T.C. Memo. 2026-81 (Sept. 3, 2026), hinges on two foundational principles of tax law: the doctrine of legislative grace and the requirement of strict compliance with statutory conditions for tax benefits. The court rejected the petitioner’s claim to a $1,400 2021 economic recovery rebate credit (ERRC) under section 6428B, holding that the inclusion of an Individual Taxpayer Identification Number (ITIN) on his return did not satisfy the statute’s requirement for a “valid identification number.”

The court began by reaffirming the longstanding principle that “tax deductions and credits are matters of legislative grace,” quoting Rickard v. Commissioner, 88 T.C. 188, 196 (1987), and Deputy v. du Pont, 308 U.S. 488, 493 (1940). This doctrine places the burden squarely on the taxpayer to prove entitlement to any claimed tax benefit. The court emphasized that this burden applies with particular force in the context of refundable credits like the 2021 ERRC, where the government’s disbursement is conditioned on strict statutory compliance.

The statutory framework governing the 2021 ERRC is set forth in section 6428B, enacted as part of the American Rescue Plan Act of 2021. Section 6428B(b)(1) provides that the credit amount is $1,400 for eligible individuals, but section 6428B(e)(2)(A) imposes a critical limitation: “the [credit] amount shall be treated as being zero unless the taxpayer includes the valid identification number of the taxpayer on the return of tax for the taxable year.” The court did not mince words in interpreting this provision. It held that the term “valid identification number” is defined in section 6428B(e)(2)(D)(i) as “a social security number issued to an individual by the Social Security Administration on or before the due date for filing the return for the taxable year.” The court found this definition to be unambiguous and exhaustive.

The petitioner argued that an ITIN constitutes a “taxpayer identification number” sufficient to satisfy the statute. The court rejected this contention, turning to the Treasury regulation that defines an ITIN and distinguishes it from a Social Security number. Under Treas. Reg. § 301.6109-1(d)(3)(i), an ITIN is “a taxpayer identifying number issued to an alien individual by the Internal Revenue Service, upon application, for use in connection with filing requirements under [title 26].” The regulation further clarifies that “the term IRS individual taxpayer identification number does not refer to a social security number.” The court cited Treas. Reg. § 301.6109-1(d)(4), which provides that a person who has or is entitled to a Social Security number “will not be issued an IRS individual taxpayer identification number.” The court concluded that the petitioner’s possession of an ITIN confirmed he did not have a Social Security number and therefore could not satisfy the statutory requirement for a “valid identification number.”

The court’s analysis underscored the distinction between a general taxpayer identification requirement and the specific eligibility criteria for the 2021 ERRC. The petitioner had argued that the IRS’s reliance on Treas. Reg. § 301.6109-1(d) to differentiate ITINs from SSNs was misplaced, as the regulation pertains to general taxpayer identification requirements rather than the specific eligibility criteria for the credit. The court firmly rejected this argument, stating that the regulation’s definition of an ITIN as not being a Social Security number directly informed the meaning of “valid identification number” in section 6428B(e)(2)(D)(i). The court held that the IRS did not exceed its authority by applying the regulation to interpret the statute; rather, the regulation clarified the statutory term in a manner consistent with Congress’s intent.

In exercising its judicial power, the Tax Court assumed a clear interpretive role, defining the scope of a statutory term that Congress had left undefined. The court did not defer to the IRS’s interpretation under Chevron deference, as the statutory language was found to be unambiguous. Instead, the court relied on the Treasury regulation to confirm the meaning of “valid identification number,” thereby reinforcing the IRS’s regulatory authority in defining terms used in the Internal Revenue Code. This aspect of the decision highlights the Tax Court’s willingness to engage in close statutory interpretation and to uphold the IRS’s regulatory framework when it aligns with the statutory text.

The court’s strict application of the statute and regulation left no room for the petitioner’s equitable arguments. The court held that the petitioner’s inclusion of an ITIN on his return did not satisfy the requirement for a valid identification number, and therefore the $1,400 credit amount was treated as zero under section 6428B(e)(2)(A). The court’s conclusion was not based on any finding of fault or intent but solely on the failure to meet the statutory condition. This result underscores the Tax Court’s commitment to enforcing the precise terms of the statute, even when the outcome appears harsh.

Jurisdictional Limits and Future Implications

The Tax Court’s ruling in Ivan Merida Ortiz v. Commissioner, T.C. Memo. 2026-81 (filed Sept. 3, 2026), underscores the court’s strict adherence to its jurisdictional boundaries—a limitation that barred the petitioner from pursuing a 2020 recovery rebate credit despite his pro se arguments. The court held that it lacked jurisdiction to consider the 2020 taxable year because the Statutory Notice of Deficiency (SNOD) issued by the IRS on July 24, 2025, addressed only tax year 2021. The Tax Court, as a court of limited jurisdiction, may exercise authority solely over taxable years included in the SNOD. The court cited Williams v. Commissioner, 131 T.C. 54, 55 (2008), and Hillenbrand v. Commissioner, T.C. Memo. 2002-303, 2002 WL 31779972, at *4, in reaffirming that deficiency jurisdiction extends only to the years specified in the notice. The petitioner’s attempt to expand the dispute to 2020 was thus foreclosed by statute, leaving the court no recourse but to dismiss the claim.

This jurisdictional gatekeeping carries broader implications for taxpayers who file pro se and may overlook the precise contours of the Tax Court’s authority. The court’s refusal to entertain the 2020 claim—despite the petitioner’s assertion of entitlement to an unreceived economic impact payment—demonstrates that the Tax Court will not stretch its jurisdiction to address matters outside the scope of the SNOD, even when the taxpayer frames the issue as a matter of fairness. The court’s decision to grant the IRS’s Motion for Judgment on the Pleadings under Rule 120(a) further signals its willingness to enforce procedural boundaries with finality, particularly when the petitioner’s arguments fail to raise a genuine dispute of material fact.

For future taxpayers using ITINs, the ruling reinforces the strict statutory requirement that a valid identification number for the 2021 recovery rebate credit must be a Social Security number issued by the Social Security Administration. The court’s holding that an ITIN does not satisfy this condition—paired with its jurisdictional refusal to consider alternative years—leaves no ambiguity: the $1,400 credit is unavailable to ITIN holders for 2021, and the Tax Court will not entertain claims for other years unless explicitly included in a deficiency notice. The decision thus serves as a cautionary tale for taxpayers who may seek to challenge IRS disallowances of credits on procedural or jurisdictional grounds, as the Tax Court’s power is circumscribed by the precise terms of the statute and the scope of the SNOD.
