The IRS is raising the price of an estate tax closing letter from $56 to $76, a $20 jump of about 36 percent. The new fee covers requests the IRS receives after October 26, 2026, under a final Treasury rule that fixes the charge at $76 per letter. Requests that arrive before the change fall under the earlier $56 rate.
What the final rule sets for Letter 627
The rule is Treasury Decision 10055, which sets the charge in section 300.12 of the user-fee regulations. Subsection (b) reads: “The fee for issuing an estate tax closing letter is $76.” Subsection (d) says the section applies to requests received by the IRS after October 26, and the regulations take effect that same day.
The IRS numbers the document Letter 627. Until now the charge was $56, a rate the Journal of Accountancy reports took effect December 1, 2025. The new $76 is $20 higher than that.
The older figure is still in circulation. An IRS page of estate tax frequently asked questions says final regulations set a $67 user fee for Letter 627 that became effective October 28, 2021. Anyone budgeting from that page will be $9 short of the new rate.
Executors and the advisers who handle estate filings now have one timing question to settle. They have to decide whether a request goes to the IRS before the change or after it, because the receipt date, not the date the estate closes, sets the price.

Why Treasury says $76 is the cost
Treasury ties the number to a biennial review of its user fees. The Independent Offices Appropriations Act and Office of Management and Budget Circular A-25 require the government to recover its full cost when a service gives someone a special benefit beyond what the general public gets. The final rule states: “The IRS has determined that the full cost to the IRS of overseeing the estate tax closing letter program is $76 per request.”
The Journal of Accountancy reports the cost study rests on about 8,053 requests a year and annual program costs of $615,593. Divide one by the other and the result is about $76. At the new fee, those requests would bring in roughly $612,000, close to the cost the IRS says it is trying to cover.
The cost model uses fiscal year 2023 and 2024 data and an IRS cost model built in 2025. The model itself was not published with the final rule. Treasury had proposed the same $76 in June, and the final rule adopts it without change.
One public comment arrived. It asked the IRS to release the cost model and more data before the fee was finalized. The agency considered the comment, declined to publish the model with the final rule and left the number alone.
Who pays, and what the rule leaves out
The fee falls on whoever requests the letter. The Journal of Accountancy describes those requesters as authorized persons and says the IRS treats the letter as a special benefit beyond what the general public receives. The rule identifies no exemptions, so no category of estate is excused from the $76.
Treasury also looked at small-business effects. Its regulatory flexibility analysis notes that decedents’ estates generally are not small entities, and it does not expect the fee to have a significant effect on small entities. For an individual estate, the practical effect is $20 more on a single request.
The rule does not describe how to submit a request or where to pay, and it contains no grace period. Those mechanics sit in separate IRS instructions for the letter. An executor should confirm them there before sending a request and a payment.
A transcript can stand in for the letter
The IRS has said for years that the letter is not the only document an estate can use. Notice 2017-12 states that an account transcript can be used in place of Letter 627, and the IRS estate tax FAQ repeats that point. An estate asked to produce the letter should find out whether a transcript would satisfy the person asking.
Authorized practitioners can view and print instant account transcripts through the Transcript Delivery Service on IRS.gov. Authorized taxpayers can request hardcopy account transcripts by mail or fax with Form 4506-T. The FAQ points to a separate IRS page with step-by-step directions.
The $76 applies to the letter, not to those transcript routes. The rule sets a fee only for issuing an estate tax closing letter. Treasury’s contact for questions about the regulations is Juli Ro Kim at (202) 317-6859, which is not a toll-free number.
Small fee, repeated resets
Twenty dollars is small next to the cost of settling an estate, but the pattern is worth following. The charge has moved from $67 in 2021 to $56 in December 2025 and now to $76, and the latest figure rests on a cost model the IRS has not published.
With the next review about two years away, estates that will need the letter later will face whatever that review finds. For anyone with a request ready to send, the open question is whether it reaches the IRS by Monday, October 26.
Is a closing letter on the estate’s to-do list?
A $20 fee increase is the visible cost, but a household settling an estate usually has bigger money still unclaimed: a surviving spouse’s Medicare Savings Program help, a property-tax break, a veterans survivor pension or forgotten accounts. Those programs are opt-in, and each has its own application and income limit.
