The IRS fee for an estate tax closing letter goes from $56 to $76 for requests the agency receives after October 26, 2026. That makes a request that arrives by October 26 $20 cheaper. The higher fee is set in a Treasury decision, TD 10055, published September 25 in the Federal Register at 91 FR 60801.
What changes on October 26
The regulation says the fee for issuing an estate tax closing letter is $76 and takes effect October 26, 2026. It applies to requests the IRS receives after that date. Those received on or before October 26 are still at the $56 fee. The trigger is the date the IRS receives the request, not the date it is mailed or the date of the person’s death, so a request in the mail on October 24 could arrive too late to count.
The fee is imposed on requests made by decedents’ estates. The notice refers to authorized persons and does not define the term further. The closing letter itself is IRS Letter 627.
Should an executor ask for the closing letter now or wait? If the estate is ready for the letter, filing before the cutoff saves $20 per request, a small amount set against the other costs of settling an estate. The reason to hurry is the date alone. Executors who have already sent a request should know that the IRS’s receipt date, not the postmark, decides which fee applies.
The closing letter fee is a $20 question for the executor, but the larger tax questions usually sit with the retiree’s own accounts and a surviving spouse’s return.

What the closing letter is for
The IRS’s estate tax FAQ describes Letter 627 as the Estate Tax Closing Letter and says that, under Notice 2017-12, an account transcript can be used in its place. A transcript can be viewed and printed instantly by authorized practitioners through the Transcript Delivery Service on IRS.gov, or requested in hard copy by mail or fax on Form 4506-T. An executor who only needs proof from the IRS about the estate tax account should ask a practitioner whether a transcript will do in place of the letter.
The same FAQ page points executors to a separate set of questions on the closing letter for how to submit a request and also names Publication 559 as a reference.
The retiree deduction a surviving spouse may see
Retirees who are survivors may meet another tax change this year. The IRS says in a newsroom summary that the new senior deduction is $6,000 for one person and $12,000 for a married couple filing jointly, with phase-outs starting at $75,000 and $150,000 of income, and that it covers tax years 2025 through 2028. The 2026 Form 1040-ES limits the deduction to taxpayers born before January 2, 1962. The IRS says the four new deductions use Schedule 1-A and are available to itemizers and non-itemizers alike, according to its Tax Tip 2026-12. A surviving spouse should check those rules for their own return; the closing letter fee has no bearing on them.
Before October 26, what an executor should have in hand
The free route is the Federal Register notice and the IRS’s closing letter questions. Confirm that the IRS has received the estate tax return, decide whether a closing letter or an account transcript is what the lender, title company or beneficiaries need, and make sure any request reaches the IRS on or before October 26. Allow for mail time. The notice says the fee turns on when the IRS receives the request.
Gather the details the request will need, and keep a copy of whatever is sent along with proof of the date it was sent. If a request will land after October 26, expect the $76 fee.
The regulation, TD 10055, is the document that sets both numbers. It states the $76 fee, the October 26, 2026 effective date and the receipt-date test, and the $56 figure is the fee it replaces.
A $20 closing letter fee is the smallest tax decision an estate faces
The estate tax closing letter costs $76 instead of $56 for requests the IRS receives after October 26, but the choices about which accounts to draw from and how to use the senior deduction can matter more to a survivor. The Retirement Tax & Withdrawal Planner includes the senior deduction, the account withdrawal order and four calculators for provisional income, IRMAA tier, RMD schedule and Roth bracket fill.
