How to Fax Form 2553 to the IRS (S Corp Election, 2026)

Form 2553 is how a corporation or an LLC elects to be taxed as an S corporation. It’s also one of the few IRS filings where fax is still the best route. Mail takes days you may not have before the deadline, there’s no online submission, and the IRS treats a fax as received the moment it arrives.

Most rejected or late elections come down to four things: the wrong fax number for your state, a missing shareholder signature, an e-signature the IRS won’t accept, or a deadline someone counted wrong. This guide covers each one, plus how to keep proof that you filed on time.

Fax numbers and rules below were checked against the IRS instructions and the IRS processing manual on October 3, 2026.

The Form 2553 fax number for your state

Route by where the corporation’s principal business, office, or agency is located, not where the shareholders live:

One trap: these regions are not the same as for other IRS forms. A Florida business faxes its 2553 to Ogden but its Form 2848 power of attorney to Memphis. If you’re faxing several forms, look each one up separately. Our IRS fax numbers guide has every chart in one place.

Getting the number right matters for more than routing. If you ever need your fax confirmation as proof, the IRS checks that it shows the correct service center for your state (more on that below).

The deadline, worked out

File Form 2553 no more than 2 months and 15 days after the beginning of the tax year the election should take effect, or at any time during the tax year before it. In practice:

• An existing calendar-year company electing S status for next year: file any time this year, or by March 15 of the year the election starts.
• A brand-new company: the clock starts on the day the tax year begins, which is the date entered on line E. The IRS’s own example: a corporation that starts on January 7 must file between January 7 and March 21. Filing before January 7 isn’t valid, because the company didn’t exist yet.
• Weekends and holidays: if the due date falls on one, it moves to the next business day.

There is no extension for Form 2553. The IRS manual says so directly. That’s why fax is the default: a fax sent on deadline day lands that day, while a mailed form depends on how you prove the mailing date.

Before you fax: the checklist that prevents rejection

Most problems with a 2553 are missing information, not wrong numbers. Run through this with the form in front of you:

1. An officer signs and gives their title. It must be the president, vice president, treasurer, assistant treasurer, chief accounting officer, or another officer authorized to sign. The instructions are blunt: an unsigned Form 2553 “won’t be considered timely filed.”
2. Every shareholder consents in column K. Each shareholder signs and dates. If a married couple holds stock as community property, both spouses sign. Joint tenants and tenants in common each sign. If you elect after the line E date, anyone who owned stock at any point since that date must also consent.
3. Sign by hand, not electronically. The IRS processing manual says fax signatures are acceptable on every signature line of Form 2553, but electronic, digital, or stamped signatures are not acceptable for an election. Print the form, sign it with a pen, then scan or photograph it. A DocuSign or typed signature is the most common modern way to get an election bounced.
4. Line E is the right date. For a new company, it’s the earliest of the date it first had shareholders, first had assets, or began doing business. That date is usually not January 1.
5. You have an EIN, or you’ve applied for one. If it hasn’t arrived, the instructions allow “Applied For” plus the date you applied. If you still need one, see the SS-4 section of our IRS fax numbers guide.
6. Box Q1 only if you mean it. Q1 asks for a fiscal year based on business purpose. It comes with a $6,200 user fee (billed later, not paid with the form) and roughly 90 extra days of processing. Most small businesses use the calendar year and skip Part II entirely.

Then fax the complete form, all 4 pages of the current revision (December 2017), plus any continuation sheet or separate consent statements. Four pages is well within Browserfax’s 20 free pages.

How to fax Form 2553 from your computer

You don’t need a fax machine, a phone line, or a trip to the print shop:

1. Print, sign, and scan. After the officer and every shareholder sign by hand, scan the pages or photograph them flat in good light. PDF, JPG, and PNG all work.
2. Open browserfax.com/app in any browser. There’s nothing to install.
3. Enter 855-887-7734 or 855-214-7520, whichever matches your state in the table above. The country is preset to the US.
4. Upload the pages. Up to 5 files are merged into one fax in the order you choose, and the page count shows before you send. Check that it says 4 pages (or more, with attachments).
5. Click Send and sign in with Google. That’s what creates your account with 20 free pages. No credit card is needed.
6. Watch it go through: Queued → Sending → Delivered, usually within a couple of minutes for a 4-page form.

If the IRS line is busy, which happens in the weeks before March 15, the fax shows Failed and the pages go straight back to your balance. Retry in a few minutes. Don’t wait until 11 p.m. on deadline day to find out the line is jammed.

Proof that you filed on time

This is where most guides are either wrong or vague, so here’s exactly what the IRS says.

The public instructions list the proof the IRS accepts if it questions whether you filed: a certified or registered mail receipt, a Form 2553 with an IRS “accepted” or “received” stamp, or an IRS letter accepting the election.

The IRS’s internal processing manual goes further for faxed elections. IRM 3.13.2.23.3 says a taxpayer who submits Form 2553 by fax “can provide a fax confirmation as proof of timely submission.” Employees are told to check two things: that the fax number on the confirmation is the right service center for the business’s state, and that the date shows the form was sent on time. The same manual makes Form 2553 a specific exception to the general rule that fax transmission reports don’t count toward timeliness.

So the fax confirmation genuinely protects you, but only if you used the correct number. Here’s what to keep:

• The Delivered email Browserfax sends. It shows the IRS fax number you sent to, the page count, and a reference ID, and your inbox records the date and time it arrived.
• The entry in your Sent history, which shows the same number with the date and time you sent it. Save it as a PDF or screenshot it.
• The signed original of Form 2553, kept with the corporation’s permanent records. The instructions require this when you file by fax.

Then watch for CP 261, the IRS’s Notice of Acceptance as an S Corporation. Once it arrives, it’s the strongest proof there is, so file it with everything else.

After you fax: what happens next

• About 60 days is the usual wait for acceptance or nonacceptance (add about 90 days if you checked Q1).
• No word after 2 months (5 with Q1)? Call the IRS at 800-829-4933. Call before re-faxing, so you know whether the first fax was logged.
• Don’t also mail it. The instructions say to send the original or fax it. If you faxed, the original stays in your files.
• Don’t file Form 1120-S for any year before the election takes effect. Until then, keep filing whatever return the business already files.

Missed the deadline? Late-election relief

A late Form 2553 isn’t the end of the election. It generally just takes effect a year later. If you need it to apply to the year you intended, Rev. Proc. 2013-30 relief is available within 3 years and 75 days of the line E date, as long as you had reasonable cause and acted diligently once you noticed:

• Write “FILED PURSUANT TO REV. PROC. 2013-30” in the top margin of page 1.
• Explain the reasonable cause on line I or in an attached statement.
• Make sure every shareholder’s column K consent covers the full period since the line E date. The consents double as the required statement that everyone reported income consistently with S status.
• File it separately, which you can do by fax to the same numbers, or attach it to Form 1120-S as the instructions describe.

If you’re outside those conditions, the remaining path is a private letter ruling with a user fee. That’s a conversation for a tax professional.

The bottom line

Faxing Form 2553 takes five minutes once it’s signed. Use the number for the state where the business is (855-887-7734 for the eastern states, 855-214-7520 for the western and southern ones). Sign by hand, including every shareholder. Send it with time to spare. Keep the Delivered confirmation and the original until CP 261 arrives. Your first 20 pages on Browserfax are free, which covers the election and then some.
