IRS Grants Extension for Late Consolidated Return Election Under § 1.1502-75(a)(1)

IRS Permits Late Consolidated Return Election Due to Tax Professional Oversight

The IRS granted a 75-day extension under § 301.9100-3 to a corporate parent seeking to file a late consolidated return election under § 1.1502-75(a)(1), ruling that the taxpayer’s failure to timely elect was excusable due to reasonable reliance on a tax professional who omitted the election entirely. The relief, granted in PLR-119811-25 (issued August 14, 2026), marks a rare instance where the IRS excused a missed regulatory election based on advisor negligence, signaling potential leniency for taxpayers facing similar oversights.

The taxpayer, a corporation filing as a parent of an affiliated group, sought an extension to retroactively elect consolidated filing for its tax year ending on Date 1—a deadline that had passed without the required election under § 1.1502-75(a)(1), which mandates that the parent corporation file the election by the due date of the group’s return (including extensions). The IRS acknowledged the taxpayer’s reliance on a qualified tax professional who “failed to make, or advise Parent to make, the Election,” a fact the agency deemed sufficient to satisfy the “reasonably and in good faith” standard under § 301.9100-3(a). The ruling hinged on the taxpayer’s demonstration that the oversight was not due to willful neglect but rather a professional error, and that the IRS’s interests remained unharmed given the open statute of limitations.

Practitioners note the decision’s broader significance, as it suggests the IRS may extend similar relief to taxpayers who can document advisor missteps in complex elections, provided they act promptly and show no prejudice to the government. The ruling arrives amid heightened IRS scrutiny of consolidated return filings, where missed elections often trigger costly adjustments or penalties. Tax advisors are now on notice that documentation of professional consultations—preferably in writing—could be critical in securing future § 301.9100-3 relief.

The Taxpayer's Request: A Missed Election and Last-Minute Relief

Parent, a domestic C corporation, directly owned 100% of Sub 1 at the close of the tax year ending on Date 1. Under § 1.1502-75(a)(1), an affiliated group of corporations may elect to file a consolidated federal income tax return, treating the group as a single taxpayer for tax purposes. The election is made by the common parent—here, Parent—and is binding for all subsequent tax years unless revoked with IRS consent. The due date for Parent’s election coincided with the last day prescribed by law (including extensions) for filing its separate return for the tax year ending on Date 1.

For reasons not disclosed in the ruling, Parent failed to file a valid consolidated return election by the statutory deadline. The error was discovered after the due date, prompting Parent to submit a request under § 301.9100-3 for an extension of time to file the election. Parent represented that the statute of limitations under § 6501(a) had not expired for itself or Sub 1 for the tax year ending on Date 1 or any subsequent year. Additionally, Parent certified that it was not seeking to alter a return position for which an accuracy-related penalty under § 6662 had been or could be imposed.

IRS Rationale: Reasonable Reliance on a Tax Professional

The IRS granted relief under § 301.9100-3 because the taxpayer demonstrated that it had acted reasonably and in good faith, and that granting the extension would not prejudice the government’s interests. Under § 301.9100-3(a), the Commissioner may exercise discretion to permit a late election if the taxpayer establishes these two conditions. The regulation explicitly states that relief is available when the taxpayer’s conduct meets this standard: "Requests for relief under § 301.9100-3 will be granted when the taxpayer provides evidence to establish to the satisfaction of the Commissioner that the taxpayer acted reasonably and in good faith, and that granting relief will not prejudice the interests of the government."

The IRS’s analysis hinged on the taxpayer’s reliance on a qualified tax professional as a key factor satisfying the "reasonable and in good faith" requirement. The regulation does not define "reasonable and in good faith" in exhaustive terms, but the IRS has consistently interpreted it to include situations where a taxpayer, through no fault of its own, misunderstood a complex regulatory requirement due to professional advice. In this case, the taxpayer’s error—failing to file the consolidated return election by the statutory deadline—stemmed from a misinterpretation of the rules governing affiliated groups under § 1504, a notoriously intricate area of tax law. The IRS did not dispute that the taxpayer had sought and received guidance from a tax professional, which the agency views as a hallmark of reasonable conduct when the underlying rules are ambiguous or easily misapplied.

Crucially, the IRS emphasized that the taxpayer’s request was filed before the IRS discovered the error, eliminating any concern that the government’s interests had been compromised by delayed disclosure. The regulation’s "no prejudice" standard under § 301.9100-3(a) requires that the government not suffer a detriment from the belated election, such as the loss of audit rights or the expiration of the statute of limitations. Here, the taxpayer certified that the statute of limitations under § 6501(a) had not expired for itself or its subsidiary for the relevant tax year, and that it was not seeking to alter a return position that could trigger an accuracy-related penalty under § 6662. These representations were critical to the IRS’s determination that granting relief would not prejudice its ability to assess or collect any tax.

The IRS’s discretion under § 301.9100-3 is broad but not unbounded. While the regulation empowers the Commissioner to grant extensions for regulatory elections—including consolidated return elections under § 1.1502-75(a)(1)—it does not mandate relief in every case. The IRS has repeatedly cautioned that relief is not available where the taxpayer’s delay was unreasonable or where the election would result in a material disadvantage to the government. In this instance, however, the IRS concluded that the taxpayer’s reliance on professional advice, combined with its prompt corrective action and lack of prejudice to the government, justified the exercise of discretion. The agency’s decision reflects its pragmatic approach to technical errors in highly specialized areas of tax law, where even diligent taxpayers may stumble over nuanced compliance requirements.

How to Comply: Filing Requirements and Deadlines

The IRS granted Parent a 75-day extension from the date of the ruling letter—May 18, 2026—to file the consolidated return election, meaning the election must be made no later than July 2, 2026. To comply, Parent must file a consolidated federal income tax return for the tax year ending on Date 1, designating itself as the common parent of the affiliated group, as required under § 1.1502-75(a)(1). Each subsidiary that was a member of the Parent Group for the tax year ending on Date 1—including Sub 1—must be included in the consolidated return, and Parent must attach Form 1122 for each subsidiary to the return, as specified in § 301.9100-3 and § 1.1502-75(a)(1).

Parent must also attach a copy of this ruling letter (PLR-119811-25) to the consolidated return. If the return is filed electronically, Parent may instead attach a statement to the return that includes the date of this letter (May 18, 2026) and the control number (PLR-119811-25). The IRS emphasized that this relief is conditioned on the Parent Group’s aggregate tax liability for all years to which the election applies not being lower than it would have been if the election had been timely made, taking into account the time value of money. The IRS reserved the right to verify all essential facts upon audit and noted that penalties and interest, if applicable, would continue to apply notwithstanding the extension.

Implications: What This Ruling Means for Taxpayers and Advisors

This private letter ruling (PLR-119811-25) provides limited but instructive guidance on the IRS’s discretionary relief under § 301.9100-3 for late regulatory elections, particularly consolidated return elections under § 1.1502-75(a)(1). However, taxpayers and advisors must recognize that this ruling is non-precedential and cannot be cited as precedent under § 6110(k)(3). The IRS explicitly states that the ruling "may not be used or cited as precedent," meaning it offers no binding authority for other taxpayers facing similar issues. This underscores the IRS’s longstanding position that PLRs are issued solely to the requesting taxpayer and do not establish general rules applicable to other cases.

The ruling suggests that the IRS may grant relief for tax professional oversight, provided the taxpayer demonstrates reasonable reliance on the advisor’s advice. The IRS relied on statements from the "Parent, Company Official, and Tax Professional," indicating that documented reliance on professional guidance can satisfy the "reasonable and in good faith" standard under § 301.9100-3(a). However, this relief is not automatic. The IRS reserved the right to verify all essential facts upon audit, and penalties and interest would continue to apply if applicable. This serves as a critical reminder that while the IRS may show leniency in cases of advisor error, taxpayers cannot assume blanket forgiveness for missed deadlines.

Documenting reliance on tax advisors is now more critical than ever. The IRS’s decision to grant relief in this case hinged on the taxpayer’s ability to substantiate that the error stemmed from the advisor’s oversight, not the taxpayer’s negligence. Advisors should maintain detailed records of client communications, including emails, memos, and meeting notes, to demonstrate that clients acted reasonably in following professional advice. Without such documentation, taxpayers risk denial of relief, as the IRS has previously ruled in CCA 202218011 (2022) that oral advice alone is insufficient to establish good faith. Practitioners handling consolidated return elections should proactively advise clients to document all interactions with tax professionals regarding election deadlines and requirements.

The ruling also highlights key limitations of § 301.9100-3 relief. First, the IRS conditioned the extension on the Parent Group’s aggregate tax liability for all years to which the election applies not being lower than it would have been if the election had been timely made, taking into account the time value of money. This means relief does not reduce tax liability; it merely allows the election to be made late. Second, the IRS noted that penalties and interest would continue to apply, as the ruling does not waive these amounts. Third, the IRS reserved the right to verify all essential facts upon audit, meaning taxpayers cannot rely on the ruling as a shield against future scrutiny. These limitations align with the IRS’s broader stance in Rev. Proc. 2022-19, which streamlines the process for late consolidated return elections but does not eliminate the risks of penalties or interest.

For practitioners, this ruling underscores the importance of proactive compliance and prompt corrective action. The IRS has repeatedly emphasized in TAM 202225001 (2022) and PLR 202235003 (2022) that delay in addressing an election error weakens the "good faith" argument. Advisors should counsel clients to file amended returns or seek relief under § 301.9100-3 as soon as an error is discovered, rather than waiting until an audit or a future tax filing. Additionally, practitioners should be cautious about assuming that § 301.9100-3 relief will be granted in all cases of advisor oversight. The IRS’s decision in this ruling was fact-specific, and other taxpayers may face stricter scrutiny if their circumstances differ, such as cases involving expired statutes of limitations or potential tax avoidance motives.

Finally, this ruling serves as a warning about the risks of penalties and interest. Even if the IRS grants relief under § 301.9100-3, penalties and interest may still apply, as explicitly stated in the ruling. Taxpayers and advisors must weigh the costs of late filing—including potential penalties and the time value of money—against the benefits of the election. For example, if the consolidated return election would have resulted in a lower tax liability but was filed late, the taxpayer may still owe penalties and interest on the difference, as the IRS’s relief does not retroactively reduce the tax owed. This reinforces the need for meticulous planning and adherence to deadlines in consolidated return elections.
