Wallace, M. (2026, October 23). IRS E-File Shutdown for Winter Maintenance Starts December 26, 2026. GreenbackTaxServices.com. Retrieved , from https://www.greenbacktaxservices.com/blog/irs-e-file-shutdown/

The IRS e-file shutdown for the 2026/2027 transition begins at 11:59 a.m. Eastern Time on Saturday, December 26, 2026, when the IRS stops accepting e-filed returns and will not reopen until January 2027. That makes December 26 the last day to e-file 2025 taxes, and any other open year, before the new filing season. The IRS announced the date on October 23, 2026, and it applies to individual and business returns alike.

Tax software can close sooner. Last year, Intuit’s professional software, which many tax preparers use to e-file, stopped on December 22, four days before the IRS, so it’s best to get your return done as soon as possible. Here is when the cutoff lands where you live, which returns to send first, and what stays open while e-file is down.

The E-File Cutoff Is 11:59 a.m. Eastern on December 26

The IRS shuts down its Modernized e-File (MeF) system in two steps. At 11:59 a.m. ET, it stops receiving new returns. Other e-file services, such as retrieving the IRS notice that a return was accepted or rejected, run until 11:59 p.m. ET. Any notice not retrieved by then waits until January, according to the IRS notice.

The Cutoff in Your Time Zone

If you live abroad, the cutoff may land in your evening or on December 27.

A December 15 Deadline Falls Before the Shutdown

If you live abroad and asked for the discretionary extra two months beyond October 15, your return is due December 15. The IRS grants that extension by letter request, as explained in Publication 54. Your deadline comes 11 days before the shutdown, so your return can still be e-filed on time. If you miss December 15, a late return can still be e-filed until the December 26 cutoff.

Christmas Falls Two Days Before the Cutoff

December 24 is Christmas Eve and December 25 is a federal holiday, so most preparers work a short week before the Saturday cutoff. Plan to finish by mid-month.

Your Preparer’s Cutoff Comes Before the IRS Cutoff

Tax software closes early to clear its queue before the IRS cutoff. Intuit says its filing center “will stop accepting e-file transmissions shortly before the IRS shutdown.”

A return finished on December 23 last year had to wait until January or be sent by mail. Expect a similar gap this year.

Late Transmissions Are Rejected or Held

The IRS does not hold returns during the shutdown, so your software determines what happens. Intuit says individual returns cannot be e-filed during the shutdown, while business returns are held on its servers until January. Either way, the return is not filed until the IRS receives it.

Which Returns to Send Before December 26

If you are behind, the shutdown is a reason to finish the oldest return first.

1. Three Tax Years Can Be E-Filed Right Now

IRS e-file accepts the current tax year plus the two before it, so your 2025, 2024, and 2023 returns can be e-filed now, including amended returns. Tax year 2023 is expected to drop out when e-file reopens in January 2027, and Intuit already lists it as “permanently shut off” after the shutdown. After that, the 2023 return is sent by mail.

2. Catch-Up Returns and Streamlined Filings

If you are catching up on late returns outside the Streamlined program, e-filing 2023 before December 26 beats mailing it next year. Earlier years go by mail regardless. Streamlined filing packages are mailed, so the shutdown does not affect them.

3. Prior-Year Extensions Cannot Be E-Filed

Extension requests on Form 4868 and Form 2350 can only be e-filed for the current filing season. An extension also cannot keep e-file open past December 26.

If you have more than one year to catch up on, our late tax return filing services can determine which returns to e-file before the shutdown and which to file by mail.

What Stays Open During the E-File Shutdown

Most other ways to file and pay continue to work.

A Government Shutdown Follows Different Rules

The e-file shutdown is planned maintenance every winter. A government shutdown happens when federal funding lapses, and IRS e-file has generally stayed open during one.

E-File Reopens in January 2027

The IRS has not announced the reopening date. The IRS began accepting individual returns on January 26, 2026, after January 27, 2025, and January 29, 2024. Business e-file usually opens about two weeks earlier. Our tax season start date update will reflect the announced date, and returns finished during the shutdown can be e-filed on opening day, except for tax year 2023 returns, which are expected to be filed by mail.

IRS E-File Shutdown Dates by Year

The IRS used to close individual e-file in November. Since 2025, individual and business returns have shared a single December cutoff.

Steps to Take Before December 26

1. Get your documents to your preparer early. Their software may close days before December 26, and a return due December 15 needs them sooner still.
2. E-file your oldest open year first. Tax year 2023 is the one expected to leave e-file in January.
3. Pay what you owe through IRS Direct Pay. Payments work during the shutdown.
4. File your FBAR separately if you still need to. FBARs go to FinCEN, which stays open.

For every other date in the year, see our expat tax deadlines guide.

Frequently Asked Questions about the E-file Shutdown

File Before the Shutdown With Time to Spare

The IRS cutoff is December 26 at 11:59 a.m. ET, and your preparer’s cutoff can come several days sooner. If you have a 2025 return to finish or older years to catch up on, starting now leaves room for questions, missing documents, and holiday closures. If you miss the window, you can still mail your return or e-file it once the system reopens in January 2027.
