The Internal Revenue Service finalized Treasury Decision 10055, officially raising the user fee required to obtain an estate tax closing letter from $56 to $76. The final rule adopts without modification the proposed regulations published in June. Known formally as IRS Letter 627, this document provides authorized representatives with written confirmation regarding the closing of an estate tax return examination or processing.
The price adjustment stems from a biennial review performed by the agency in 2025. Under the Independent Offices Appropriations Act of 1952, federal agencies are directed to ensure specialized services provided to specific individuals remain self-sustaining. In its review, the agency evaluated both direct and indirect operational costs for the program, calculating total annual expenses at $615,593. Dividing those expenses across an anticipated volume of 8,053 annual requests yielded the updated $76 per-request fee structure.
During the public rulemaking window, Treasury and the IRS received a single written comment regarding the proposed increase. The submitter requested further details concerning the agency's underlying cost model and asked for additional data before the regulations were finalized. After reviewing the feedback, agency officials determined that the initial calculations accurately reflected necessary cost-recovery levels and adopted the proposed text without changes.
For estate executors, personal representatives, and tax professionals managing estate administrations, the rule establishes a specific timeline for submission costs. An estate tax closing letter offers practical value by confirming that the federal estate tax return review is concluded, helping fiduciaries distribute assets with greater certainty. Requests received by the IRS prior to October 26, 2026, remain subject to the $56 rate that took effect on December 1, 2025, while any requests submitted on or after October 26, 2026, will require the updated $76 payment.
