Form 2553 is the IRS document used to elect Subchapter S corporation status. By filing this form, a qualified small business can pass its income, losses, deductions, and credits directly to shareholders, avoiding double taxation. The election must be submitted by a specific deadline—generally within two months and 15 days after the beginning of the tax year—so timing is critical.
The method you choose to deliver the form—fax or traditional mail—can affect how quickly the IRS receives it, the cost you incur, and the level of proof you have that the filing was completed correctly. Understanding each option helps you avoid missed deadlines and unnecessary back‑and‑forth with the agency.
Faxing Form 2553 is a fast, electronic alternative to mailing a paper copy. The IRS maintains a dedicated fax line for S‑Corp elections, and most tax professionals still keep it on file. When you fax, you receive an automatic receipt that can serve as evidence of timely submission.
Because the fax transmission is immediate, you can confirm delivery within minutes. However, you must ensure the fax quality is legible and that all required signatures are clearly visible. A failed transmission or a garbled page can cause the IRS to reject the filing, requiring a re‑fax or a mail submission.
Mailing Form 2553 remains the most familiar method for many small‑business owners. The IRS provides a specific address for S‑Corp elections, and you can send the form via standard first‑class mail, certified mail, or a courier service. Certified mail offers a tracking number and a return receipt, providing a clear audit trail.
While mailing can take several days to reach the IRS, it also allows you to include supporting documentation, such as shareholder consent letters, without worrying about fax quality. The downside is the slower turnaround and the additional cost of certified mail or courier services.
Below is a side‑by‑side comparison of the two delivery methods. Use this table to gauge which option aligns with your deadline, budget, and risk tolerance.
| Factor | Fax | |
|---|---|---|
| Typical Delivery Time | Minutes to a few hours | 2–5 business days (standard) or 1 day (courier) |
| Cost per Submission | Phone line charges (often free with office phone) | $0.55 (first‑class) up to $7–$12 for certified or courier |
| Proof of Delivery | Fax receipt with timestamp | Certified mail receipt or courier tracking |
| Risk of Rejection | Higher if fax quality is poor | Lower, but delayed if mail is lost |
| Security | Potential interception on unsecured lines | Physical documents can be opened if not sealed |
For most businesses facing a tight filing deadline, fax is the fastest route, provided you have a reliable fax machine or an online fax service. If you prefer a tangible paper trail and are less constrained by time, mailing—especially certified—offers a more formal record.
The IRS requires that Form 2553 be complete, accurate, and signed by all required parties. Whether you fax or mail, you must retain copies of the submitted form and any proof of delivery. Failure to keep these records can complicate audits or lead to denied elections.
Security is another key factor. Fax transmissions over analog lines can be intercepted, while digital fax services should use encrypted channels (TLS). When mailing, use a sealed envelope and consider a tamper‑evident tape if the documents contain sensitive shareholder information.
Choosing between fax and mail often comes down to three questions: How soon do you need proof of filing? What is your budget for the submission? How comfortable are you with electronic versus physical records?
Use the checklist below to make an informed decision:
Once you’ve weighed these factors, you’ll know whether to head to the fax machine or the post office. For quick reference, the where to fax form 2553 page offers the exact IRS fax number and additional filing tips.
No. The IRS does not accept email submissions for Form 2553. The only electronic option is fax, while the traditional method is mailing a hard copy.
Check the fax confirmation for error codes. If the transmission was unsuccessful, resend the fax or switch to certified mail to ensure timely delivery.
A cover sheet is optional but recommended. It should list your business name, EIN, and the purpose (“Form 2553 S‑Corp Election”) to help the IRS route the document correctly.
Filing Form 2553 itself is free. Any costs you incur are limited to fax line charges, postage, or courier fees.
Yes. Submit a corrected Form 2553 with a clear label (e.g., “Amended”) and include a brief explanatory letter. Use the same delivery method you originally chose, or switch to the other method for added confirmation.
Both fax and mail are valid ways to get Form 2553 to the IRS, and each has distinct advantages. Fax offers speed and low cost, while mail—especially certified—provides a robust paper trail and peace of mind. By understanding the practical steps, costs, and security implications of each method, you can confidently choose the delivery option that aligns with your business’s timeline and compliance needs.
Remember to keep every receipt—whether a fax confirmation or a certified‑mail tracking number—in your corporate records. Proper documentation not only satisfies IRS requirements but also safeguards your S‑Corp election against potential disputes.
