The IRS routes on your principal business, office or agency. If you formed the entity in Delaware, Wyoming or Nevada but run it from Pennsylvania, you use the Kansas City center above. Filing on the basis of your state of incorporation is the single most common routing mistake.

Your next deadline
For a calendar-year business electing for 2027, the deadline is March 15, 2027. You can file at any time during 2026 for a 2027 effective date. There is no extension. How the deadline is calculated.
Before you send it
- Sign and date page 1 by hand. The IRS did not make those boxes fillable, so they cannot be typed.
- Have every owner sign and date Column K on page 2. A typed name is not a consent, and a missing one is the most common rejection reason.
- Print in black and white — black text faxes far more reliably than color.
- Make a complete copy for your records before sending.
- If mailing, send the original rather than a photocopy, and use certified mail with return receipt.

Faxing is faster and gives you an immediate transmission report. Certified mail with return receipt gives you dated proof of filing, which is stronger evidence if the IRS later says it never arrived. Keep whichever proof you get — it is the only thing that establishes your filing date. If you mail it, send the original rather than a photocopy.

Questions about filing from Pennsylvania
Where do I mail Form 2553 from Pennsylvania?
Send it to the IRS Kansas City service center: Department of the Treasury, Internal Revenue Service, Kansas City, MO 64999. If you are using a courier such as FedEx or UPS, use the street address instead: Internal Revenue Submission Processing Center, 333 W. Pershing, Kansas City, MO 64108.
What is the fax number for Form 2553 in Pennsylvania?
855-887-7734. That is the IRS Kansas City service center, which handles 24 jurisdictions including Pennsylvania. Keep the transmission confirmation — it is your proof of filing.
I incorporated elsewhere but operate in Pennsylvania. Which address applies?
Pennsylvania, because the IRS routes on your principal business, office or agency rather than your state of incorporation. A Delaware or Wyoming entity operated from Pennsylvania uses the Kansas City center.
Does Pennsylvania need anything beyond the federal election?
Essentially no PA entity-level income tax: the capital stock/franchise tax was eliminated for tax years beginning January 1, 2016 and after, and a PA S corp owes corporate net income tax only to the extent of built-in gains (7.99% for 2025, 7.49% for 2026). The recurring obligations are nonresident shareholder withholding at 3.07% and a $7 Department of State annual report. Pennsylvania automatically recognizes the federal S election: "Federal subchapter S corporation elections will automatically be a Pennsylvania S corporation." There is nothing to file to become a PA S corp.
How long does the IRS take to respond?
The IRS says to expect Notice CP261 within about 60 days. It does not publish a live processing estimate for Form 2553, so treat that as its stated expectation rather than a guarantee. If nothing arrives, call 800-829-4933 with your proof of filing.
