IRS Notice 2026-63, 2026-42 I.R.B. ___ (Sept. 30, 2026)

On September 30, 2026, the Internal Revenue Service released Notice 2026-63, granting comprehensive administrative tax relief under Internal Revenue Code (I.R.C.) § 7508A to individuals and entities impacted by the ongoing terroristic action in the State of Israel throughout calendar years 2025 and 2026. This administrative guidance extends statutory deadlines for time-sensitive tax compliance obligations that were due to be performed on or after September 30, 2026, and before September 30, 2027, postponing the required performance date to September 30, 2027.

The notice addresses an evolving humanitarian and security crisis, serving as the latest installment in a sequence of relief measures. The IRS previously issued Notice 2023-71, Notice 2024-72, and Notice 2025-53 to assist taxpayers affected by terroristic actions in the region. Notice 2026-63 formally bridges these prior grants of relief, establishing that for eligible taxpayers, acts previously postponed through September 30, 2026, under Notice 2025-53 are further postponed through September 30, 2027.

Administrative Rationale and Legislative Intent

The Treasury Department and the IRS issued Notice 2026-63 to alleviate administrative and procedural burdens imposed on taxpayers whose capacity to meet federal tax obligations has been severely disrupted by armed conflict and terrorist activity. Recognizing that individuals and commercial enterprises operating in or linked to the covered geographical region face severe operational constraints—including physical destruction of business records, displacement, disruption of communication channels, and unavailable professional tax preparers—the IRS exercised its statutory discretionary relief powers.

Furthermore, the notice reflects executive coordination among federal departments. In issuing Notice 2026-63, the IRS fulfilled statutory and procedural prerequisites requiring inter-agency consensus before declaring foreign events as terrorist actions for tax administration purposes. The administrative rationale balances taxpayer equity by preventing interest, failure-to-file penalties, and failure-to-pay penalties during periods of extreme hardship, while simultaneously granting the IRS extended statutory windows to perform necessary audit, assessment, and collection functions.

Statutory Framework and Analysis of Internal Revenue Code Provisions

The IRS’s grant of relief in Notice 2026-63 is grounded primarily in I.R.C. § 7508A(a). Section 7508A(a) provides the Secretary of the Treasury or the Secretary’s delegate with explicit statutory authority to postpone the time, up to one year, for performing certain acts under the internal revenue laws for a taxpayer determined by the Secretary to be affected by a “terroristic or military action as defined in section 692(c)(2).”

To establish the statutory predicate for § 7508A relief, the IRS analyzed I.R.C. § 692(c)(2). Under § 692(c)(2), the term “terroristic action” is strictly defined as “any terroristic activity which a preponderance of the evidence indicates was directed against the United States or any of its allies.”

To operationalize this statutory definition when foreign events are involved, the IRS applied Section 4.01(1) of Revenue Procedure 2004-26, 2004-1 C.B. 890. Section 4.01(1) provides that prior to publishing a determination that an event outside the United States constitutes a terroristic action within the meaning of § 692(c)(2), “the Secretary will ascertain whether the Department of State and the Department of Justice believe that a preponderance of the evidence indicates that the event resulted from terrorist activity directed against the United States or its allies.”

In applying this legal procedure, Notice 2026-63 records that “On September 30, 2026, in accordance with the procedures described in Rev. Proc. 2004-26, the Secretary of the Treasury determined that the terrorist activity throughout 2025 and 2026 against the State of Israel constitutes terroristic action within the meaning of section 692(c)(2).” This formal administrative finding satisfied all statutory conditions required to invoke the postponement powers under § 7508A(a).

Application of Statutory Authority to Affected Taxpayers

Having established the statutory threshold, the IRS defined the specific classes of qualifying taxpayers. Pursuant to Treasury Regulation (26 C.F.R.) § 301.7508A-1(d)(1), the Secretary identified five distinct categories of “affected taxpayers” eligible for relief under Notice 2026-63:

Individuals and Business Entities in Covered Areas: “Any individual whose principal residence, and any business entity or sole proprietor whose principal place of business, is located in the State of Israel, the West Bank or Gaza (covered area);”
Relief and Philanthropic Personnel: “Any individual affiliated with a recognized government or philanthropic organization, and who is assisting in the covered area, such as a relief worker;”
Taxpayers Dependent on Regional Records or Preparers: “Any individual, business entity or sole proprietor, or estate or trust whose tax return preparer or records necessary to meet a deadline for postponed acts are located in the covered area;”
Spouses of Affected Taxpayers: “Any spouse of an affected taxpayer, solely with regard to a joint return of two married individuals;” and
Casualties and Victims: “Any individual visiting the covered area who was killed, injured, or taken hostage as a result of the terroristic action.”

From an administrative implementation standpoint, the IRS noted that it “automatically identifies taxpayers whose principal residence or principal place of business is located in the covered area based on previously filed returns and applies relief.” However, for affected taxpayers qualifying through indirect ties—such as having records or preparers in the covered area, or acting as relief workers—automatic identification is impossible. Notice 2026-63 instructs these taxpayers to proactively request relief by contacting the IRS disaster hotline at (866) 562-5227 or the international caller line at (267) 941-1000.

Scope of Postponed Taxpayer and Government Acts

Notice 2026-63 details the specific operational acts postponed until September 30, 2027. The scope encompasses both taxpayer compliance duties and administrative government actions.

Postponement of Taxpayer Acts

Under Treas. Reg. § 301.7508A-1(c)(1) and Revenue Procedure 2018-58, 2018-50 I.R.B. 990, affected taxpayers have until September 30, 2027, to perform time-sensitive acts that were originally due to be performed on or after September 30, 2026, and before September 30, 2027. Notice 2026-63 explicitly enumerates key postponed acts, including:

“Filing any return of income tax, estate tax, gift tax, generation-skipping transfer tax, excise tax (other than firearms tax), harbor maintenance tax, or employment tax;”
“Paying any income tax, estate tax, gift tax, generation-skipping transfer tax, excise tax (other than firearms tax), harbor maintenance tax, or employment tax, or any installment of those taxes;”
“Making contributions to a qualified retirement plan;”
“Filing a petition with the Tax Court;”
“Filing a claim for credit or refund of any tax; and”
“Bringing suit upon a claim for credit or refund of any tax.”

Postponement of Government Acts

In addition to granting relief to taxpayers, Notice 2026-63 postpones key statutory government actions under Treas. Reg. § 301.7508A-1(c)(2). For affected taxpayers, any government act due to be performed on or after September 30, 2026, and before September 30, 2027, is postponed until September 30, 2027. These acts include:

“Assessing any tax;”
“Giving or making any notice or demand for the payment of any tax, or with respect to any liability to the United States in respect of any tax;”
“Collecting by the IRS, by levy or otherwise, of the amount of any liability in respect of any tax; and”
“Bringing suit by the United States, or any officer on its behalf, in respect of any liability in respect of any tax; and allowing a credit or refund of any tax.”

Interplay with Prior Administrative Relief Notices

Notice 2026-63 provides detailed guidance regarding its cumulative interaction with prior relief notices, specifically Notice 2023-71, Notice 2024-72, and Notice 2025-53. Notice 2025-53 had previously postponed due dates to September 30, 2026, for acts due on or after September 30, 2025, and before September 30, 2026.

Notice 2026-63 establishes a seamless administrative bridge for ongoing conflict conditions: “Because September 30, 2026, is the first day of the postponement period provided by this notice, taxpayer acts postponed by Notice 2025-53 (including, for taxpayers eligible for the applicable prior notices, acts previously postponed by Notice 2024-72 and Notice 2023-71) are further postponed until September 30, 2027, for taxpayers eligible for relief under this notice.”

Importantly, the IRS emphasizes that this continuous postponement applies strictly to taxpayers eligible under Notice 2026-63. “Taxpayers eligible for relief under Notice 2025-53 who are not also eligible for relief under this notice have until September 30, 2026, to perform the time-sensitive acts postponed by Notice 2025-53.” Similarly, government acts previously postponed under Notice 2025-53 until September 30, 2026, are further postponed until September 30, 2027, solely for taxpayers qualifying under both notices.

Conclusions and Strategic Practice Considerations

IRS Notice 2026-63 provides essential administrative relief for client populations affected by foreign conflict, but tax practitioners must exercise careful technical diligence when advising clients relying on this guidance.

First, practitioners must emphasize to clients that “In the absence of another separate determination and grant of relief before September 30, 2027, all time-sensitive acts postponed until September 30, 2027 under this notice, including acts previously postponed under Notice 2023-71, Notice 2024-72, or Notice 2025-53, must be performed by September 30, 2027.”

Second, practitioners must strictly distinguish a statutory postponement under I.R.C. § 7508A from a standard administrative extension of time to file. Notice 2026-63 explicitly clarifies: “The postponement period provided in this notice is not the same as an extension of time to file a tax return. Different extension-of-time-to-file rules apply depending on the return and the taxpayer’s circumstances.” Practitioners should note that if a client requires time beyond September 30, 2027, they must file a formal extension request prior to the applicable deadline. Furthermore, “An extension of time to file is not an extension of time to pay and may therefore result in interest or penalties for late payment.”

Finally, for clients whose preparers or records are in the covered region, practitioners should document eligibility thoroughly and proactively contact the IRS disaster assistance hotline to ensure the proper relief indicators are placed on the client’s master file account before September 30, 2027.
