Estate Tax Closing Letter Fee: $76 Since Oct 26, 2026

What changed on October 26, 2026

An estate tax closing letter is the IRS’s written record that it has accepted an estate’s Form 706 or finished examining it. The service carries a user fee under the Independent Offices Appropriations Act of 1952 (31 U.S.C. 9701), and OMB Circular A-25 tells agencies to review such fees every two years and set them at full cost. The IRS did that review in 2025, and it produced a higher number.

Two details are easy to miss. First, the regulation says the fee applies to requests received “after October 26, 2026,” so the text does not say which fee governs a request received on October 26 itself; the IRS notice on its About Form 706 page (dated October 5, 2026) uses the same words, “after October 26, 2026.” Second, the one commenter asked the IRS to publish its cost model before finalizing. The IRS answered that the cost model and data “will not be part of the final regulations,” and that the data needed for comment was in the proposal’s preamble. It also said it expects no costs to fall on small professional firms, because decedents’ estates are generally not “small entities.”

Where $76 comes from: the IRS cost models side by side

The IRS shows its arithmetic in the proposal. Putting the 2023 model (which produced $56) next to the 2025 model (which produced $76) shows why the fee rose even though the IRS processes fewer requests.

Dividing the published figures gives $56.51 for the 2023 model and $76.44 for the 2025 model (our arithmetic); the IRS prints whole dollars. The driver is not volume. Fewer requests spread a larger cost over fewer letters, and the labor cost per full-time equivalent rose 37.8%, and the reported grade mix moved from mostly GS-5 to a mix of GS-5, GS-8 and GS-11. At 8,053 requests a year, $76 would bring in about $612,028, against $450,968 at $56 (our arithmetic). The IRS says the increase “reflects the change in the IRS costs of administering the program as a result of changes in operational factors.”

For scale, the IRS Data Book 2025 counts 28,495 estate tax returns (Form 706 series) filed in fiscal 2025 and 31,516 in fiscal 2024. The 8,053-a-year request average is about 28% of the fiscal 2025 count (our arithmetic), but the two numbers cover different years and populations, so treat that as a rough sense of how many estates ask for the letter. Our federal estate tax collections by state page breaks down the return counts.

How to request the letter, step by step

The steps below come from the IRS Frequently asked questions on the Estate Tax Closing Letter (last reviewed August 19, 2026) and the Instructions for Form 706 (Rev. July 2026). The fee line on that FAQ page is behind the new rule; the process is not.

The Form 706 instructions are more compact: a closing letter “will not be issued unless a request is made via Pay.gov,” and the executor should wait “at least 9 months after filing Form 706.” Those instructions still point readers to T.D. 10031 for the fee, a rule since replaced twice, so the printed instructions and the FAQ both lag the $76 fee. Our Form 706 guide covers the return itself and how the 9-month filing date is set.

Worked timeline (our arithmetic)

Suppose an estate files Form 706 on July 1, 2026 and the account transcript does not yet show code 421. Nine months later is April 1, 2027, the earliest date the IRS tells it to request. The fee is $76 if the fee rule stays as published. If the estate also files a supplemental return and wants a letter for that return too, it makes a second request and pays $152 in total. If the request goes in on April 1, 2027, 120 more days is July 30, 2027, the earliest date the IRS’s status-call rule would allow a call to 866-699-4083, and only if the letter has not arrived.

Who gets the letter, and what the fee does not buy

The IRS mails the letter only to the executor listed on Form 706 (lines 6a and 6b, or Form 706-NA lines 9a and 9b) and to representatives named on Form 2848 or Form 8821 for that return. It does not use the address typed into Pay.gov. A co-executor who is not the line 6a executor generally gets nothing unless the estate’s address of record is changed first: a duly authorized co-executor can file Form 56 and then Form 8822, and the IRS asks for 4 to 6 weeks to process the address change before the request.

Other rules from the same FAQ:

• Amended or supplemental return: a separate request and an additional fee, with no refund on the ground that a letter was already issued for the earlier return.
• Too-early or duplicate requests: refunds “ordinarily” are not issued for a request made before code 421 posts, or for more than one request on the same return. The letter issues after code 421 posts.
• Refund requests: sent by e-mail to the address on the FAQ page, with the Pay.gov Tracking ID.
• Transfer certificates: the closing letter is not a transfer certificate and does not include one.

A closing letter also does not release the executor from personal liability. That is a separate request under 26 U.S.C. 2204; our executor personal liability guide sets out the clocks.

The free alternative: the account transcript

Notice 2017-12 lets an account transcript stand in for Letter 627. The IRS transcripts page (last reviewed October 29, 2026) says that for estate tax returns filed on or after June 1, 2015, closing letters are issued only on request, and that authorized practitioners can view account transcripts instantly in the Transcript Delivery Service. A hardcopy transcript can be requested on Form 4506-T and is mailed to the address of record. For that route the IRS says the audit decision is typically made six months after filing, so wait six months before asking. Code 421 shows “Closed examination of tax return” in all cases, so the description alone does not tell you whether an audit took place. If code 421 is absent, the return remains under review.

Whether a lender, title company, state tax office or transferee will accept a transcript instead of the letter is up to that third party; the IRS pages we read do not say. The estate’s attorney should ask before the estate chooses.

Two IRS pages that disagree with the rule

On November 2, 2026 we found three places where the IRS’s own pages lag the regulation. They are worth knowing because the pages are what executors and preparers read first.

The rule in the Federal Register governs. A reader who sees $56 on the FAQ page should still expect $76 for a request received after October 26, 2026, and should check the amount on the Pay.gov screen.

What a reader can do with this

• Do not pay early. Look at the account transcript first. Without code 421, a request made too soon is not refunded, and the letter waits until the code posts.
• Count 9 months from the filing date of Form 706, not from the date of death, then add 30 days after any examination ends.
• Make sure the letter will reach the right person. Confirm the executor’s address on Form 706 line 6b, and send Form 8822 early if it changed.
• If you are a co-executor, ask the line 6a executor for a copy or file Form 56 and Form 8822 before the request.
• One request per return. Duplicates are charged and not refunded.
• Keep the Pay.gov Tracking ID in the estate file; the helpline and any refund request ask for it.
• Ask the people who need the letter whether a transcript will do, before spending $76.
• After a death with real estate: the basis report to heirs runs on separate dates from the closing letter; see our Form 8971 and date-of-death appraisal page.

Who decides, and what to bring

Whether to pay for the letter or rely on a transcript, and when to distribute the estate, are decisions to make with the estate’s attorney and CPA. If the estate holds rentals, an LLC or fund shares, an adviser who sees the whole estate can help line up the return, the closing letter and the sale or distribution dates.
