Where to Fax Form 2553

Form 2553 goes to one of two IRS fax numbers: 855-887-7734 for the Kansas City service center, or 855-214-7520 for Ogden. Which one is yours turns on a single question — where the business actually operates.

It is not the state you incorporated in. The IRS routes on the corporation's principal business, office, or agency, which is the place the business is genuinely run from. A Delaware LLC operated out of San Diego is an Ogden filer. A Wyoming corporation whose only office is in Boston is a Kansas City filer. Misrouting on the state of formation is the single most common Form 2553 filing error, and Delaware-formed startups are the population it catches most often.

Enter the state you actually operate from below to get the fax number, the mailing address, and the courier address for that center — or open the full IRS mailing address and fax number for your state on its own page.

Fax or mail?

Form 2553 cannot be e-filed, so those are the only two channels. Faxing is the better default for almost everyone: it costs little, it confirms in minutes, and it produces a dated receipt the same day. Mail is worth using when you cannot get a clean transmission through, or when you want a physical return receipt on file.

If you mail it, send it certified with return receipt requested. A plain first-class envelope leaves you with nothing to show. And if you use FedEx or UPS, you need the service center's street address rather than the standard one — private carriers cannot deliver to the IRS's bare city-and-ZIP format. The lookup above shows both, and where to mail Form 2553 covers the postal route in full.

What to put in the fax

Send the package as one transmission, in this order:

1. 1Your cover sheet.
2. 2Page 1, signed and dated in ink by an officer. The Signature and Date boxes are not fillable in the official Form 2553 PDF — only Title is — so this page has to be printed and signed by hand.
3. 3The shareholder consent page, with every signature in Column K written by hand. It holds exactly seven shareholders; if you have more, include the extra copies of that page immediately after it.
4. 4The Part II, Part III or Part IV pages only if they apply to you. Most filers complete none of them.
5. 5Any attachment — a late-election statement, a shareholder list that would not fit, a QSST election.

Do not fax the IRS instruction pages, and do not attach a Form 8832. If you are unsure what belongs in each box, work through the line-by-line instructions before you print.

The cover sheet

One page, plain, and no more than the following. Nobody reads a cover sheet for substance; its whole job is to let the receiving clerk match your pages to your file and notice if any dropped.

• The entity's exact legal name, spelled as it appears on the form and in IRS records for the EIN — not a trade name.
• The EIN.
• "Form 2553 — Election by a Small Business Corporation."
• Total page count including the cover sheet. This is the one field that does real work: it is how a short transmission gets spotted.
• A contact name and daytime phone number.

Leave off the explanations. A cover letter arguing your reasonable cause, a note asking for expedited handling, a paragraph about your accountant — none of it is read, and none of it counts as part of your filing.

The transmission report is your filing

Once the fax goes through, the report your machine or fax service produces is the only contemporaneous evidence that you filed, and on what date. The IRS sends nothing back by fax. There is no acknowledgment, no reference number, and no way to check status online.

So before you file the report away, read it:

• Check the destination number digit by digit against the number for your service center. A transposed digit produces a perfectly successful-looking report for a fax that went somewhere else.
• Check the page count matches what you fed in, cover sheet included. A report can say OK on a partial send.
• If it came up short, resend the entire package, not the missing pages. Loose pages arriving separately cannot be matched to your file.
• Save it as a PDF and keep it permanently. Not for three years — permanently. An S election has no expiry date, and the buyer's lawyer in a sale eight years from now will ask for proof that it was validly made.

If the fax will not go through

1. 1Re-dial, then try off-peak

   A busy signal is usually just volume. Early morning and late evening are markedly easier than the middle of a weekday, especially in February and March.

2. 2Change the sending route

   If a physical machine on an analog line keeps dropping the handshake, try an online fax service instead — or the reverse. The two negotiate differently with the receiving equipment.

3. 3Simplify the file

   Send black and white at standard resolution. Color scans, phone photographs of a printed form, and very high-DPI PDFs all fail more often and scan worse at the other end.

4. 4Fall back to mail

   After a day or two of genuine failures, print it and send it certified with return receipt to the mailing address for the same service center. Keep the failed transmission reports: together with the certified receipt they show what you attempted and when.

5. 5Do not do both once one has worked

   If a fax went through cleanly, stop. Sending the same election twice through two channels invites duplicate processing and a second look at your file, with no benefit.

You keep the original

This catches people out. When you fax, the IRS receives an image and the signed paper stays with you — nothing needs to be mailed afterwards to "complete" the filing. That signed original is now a permanent corporate record. Store it with the transmission report and, when it arrives, the acceptance notice.

You will be asked for that set more often than you expect: by a payroll provider setting up your S-corp accounts, by whoever prepares your first Form 1120-S, by a bank, and by any buyer or investor conducting diligence.

After it goes through

Acceptance arrives as Notice CP261 in the post. The IRS states a timeframe of roughly 60 days, but it does not publish a live processing estimate for Form 2553, so treat that as an expectation rather than a promise — Form 2553 processing time covers what happens after you file. If nothing has arrived after 60 days, call the Business and Specialty Tax Line on 800-829-4933 with the transmission report in front of you.

In the meantime, the election is not conditional on receiving CP261 — a validly filed election is effective from the date on line E. What it is conditional on is you actually running payroll and paying yourself a defensible salary from that date. And if you were hoping to skip the paper entirely, there is no e-file path for Form 2553; the one narrow exception involves attaching a late election to a Form 1120-S.

If you operate outside the 50 states

The IRS publishes no Form 2553 filing address or fax number for entities whose principal business, office, or agency is outside the 50 states and the District of Columbia. Forms 1120-S and SS-4 have foreign routing rows; this one does not. Rather than guess at a number, call the Business and Specialty Tax Line on 800-829-4933 and ask where to send it.
