The IRS will charge $76 for an estate tax closing letter on any request it receives after October 26, 2026, up from $56, under a final Treasury and IRS regulation published in the Federal Register on September 25. The $20 increase is a 35.7 percent jump, and it applies per request, so an executor weighing when to ask for the letter faces a fee that changes on a fixed calendar date.
The closing letter, IRS Letter 627, is the document the IRS issues, on request, to verify that an estate tax return has been closed. The regulation sets only the price of that letter. It does not change who may request one or how the request is made.
The fee goes from $56 to $76 for requests received after October 26
The final rule describes itself as final regulations “relating to the imposition of a user fee on authorized persons requesting the issuance of IRS Letter 627, also referred to as an estate tax closing letter.” Its text increases the fee “from $56 to $76.” The regulations are effective October 26, 2026, and the applicability provision reads: “This section applies to requests for estate tax closing letters received by the IRS after October 26, 2026.”
Because the language says “after,” a request that reaches the IRS on October 26 itself falls under the old $56 fee, while one that arrives on October 27 or later falls under the new $76 fee. The document closes with the name of Frank J. Bisignano, Chief Executive Officer, and records approval on September 2, 2026 by Kevin M. Salinger, Acting Assistant Secretary of the Treasury (Tax Policy). It lists Juli Ro Kim at (202) 317-6859 as the contact for questions about the regulations, and the IRS CFO Cost and User Fees office at (202) 317-6400 for questions about cost methodology.
According to the rule, the new amount is set by the IRS 2025 Cost Model using fiscal year 2023 and 2024 cost data under Office of Management and Budget Circular A-25, the federal guidance on charging for government services. The rule also states that estates are not small entities, so the agency performed no small-entity analysis.
The date that counts is the day the IRS receives the request
The cutoff is tied to receipt. The rule’s applicability sentence counts requests “received by the IRS,” so the fee follows the day of arrival and not the day a request was prepared. A request that reaches the IRS in November pays the higher fee.
That matters because the fee is not collected on the estate tax return itself. The IRS’s frequently asked questions on the estate tax closing letter, last reviewed August 19, 2026, say the letter is not issued automatically. A request is made separately, through Pay.gov, by searching for “estate tax” or “closing letter” and selecting the Estate Tax Closing Letter User Fee. The fee can be paid by bank account (ACH), PayPal, Venmo, or debit or credit card.
A nine-month wait narrows who can use the old fee
The same IRS page says not to make the request “until at least 9 months after filing the estate’s Form 706” (or Form 706-NA), and, if the return was examined, “at least 30 days after the completion of the examination.” Calendar arithmetic shows what that does to the cutoff. For a request to reach the IRS by October 26, 2026, the return would have had to be filed by about January 26, 2026, and an estate whose return was examined would need the examination closed at least 30 days earlier. An estate that filed later has not reached the nine-month point by October 26 and will pay $76 whenever it asks.
The page names three kinds of people who may make the request: the executor listed on Form 706, an authorized representative holding a Form 2848 power of attorney, or a designee on a Form 8821 tax information authorization. Nothing on the page makes paid assistance a condition. The executor is the first person it lists, the route is the IRS’s own Pay.gov request, and the only charge it describes is the IRS user fee itself. For status, the page gives the IRS number 866-699-4083 for callers who have waited more than 120 days after a request.
The fee has already moved twice in a little over a year
The $76 figure follows a reduction. An IRS notice, Estate tax closing letter fee reduced to $56 effective May 21, 2025, lists the previous fee as $67 and the new one as $56, for requests made on or after that date. The IRS questions-and-answers page still states $56 for requests made on or after May 21, 2025, which is accurate until the new rule’s cutoff arrives. The step from $56 to $76 therefore leaves the fee $9 higher than the $67 charged before the May 2025 cut.
The same questions-and-answers page also says that account transcripts “may be an acceptable substitute” for the letter in some situations. The page does not say which situations, and the regulation does not address the point.
The Federal Register document remains the controlling record for the fee, the October 26, 2026 cutoff and the receipt-based wording. The IRS page on requesting the letter, reviewed in August 2026, controls the route and the nine-month waiting period.
Tracking an IRS matter that is still open
The IRS Refund Recovery Kit is written for taxpayers waiting on a refund that is late, reduced or offset, or holding an IRS notice they cannot place. It does not cover estate tax closing letters or any other estate filing, and it is not a substitute for the IRS’s own pages on them.
The IRS Refund Recovery Kit includes a notice decoder, the refund-trace steps that use Form 3911, and a refund status tracker spreadsheet for following an IRS matter from one date to the next.
