Starting a business is hard enough; navigating IRS paperwork shouldn't be. If you've decided that S-Corp status is the right move for your company's tax strategy, Form 2553 is your golden ticket.
The problem? The IRS is notorious for paperwork "going missing" in the mail. If your election form isn't received by the deadline, you lose those tax benefits for the entire year. This is why savvy entrepreneurs and CPAs have ditched the post office in favor of digital faxing.
Why Faxing is the "Pro Move" for Form 2553
While the IRS is slowly modernizing, they still don't allow you to simply "email" Form 2553. Your options are snail mail or fax. Here’s why faxing via mFax.to wins every time:
- The "Receipt" is Your Insurance: When you fax, you get a digital transmission report. If the IRS ever claims you didn't file on time, that report is your legal proof.
- Skip the Processing Delay: Mailed forms can sit in a bin for weeks before being opened. Faxes are digitized almost immediately upon arrival at the IRS service center.
- Secure & Private: Unlike an envelope that can be opened or lost, mFax uses enterprise-grade encryption to ensure your EIN and sensitive data go straight to the IRS. Learn more about is online fax secure?
- Sign & Edit on the Go: No printer? No problem. You can sign your Form 2553 digitally right from your phone before sending.
Where Do You Fax IRS Form 2553?
The fax number for Form 2553 depends on the state where your principal business office is located. The IRS routes S-Corp elections through two processing centers: fax to 855-214-7520 if you're in Group A states (FL, GA, MS, NC, RI, SC, WV, and foreign entities), or 855-887-7734 for most other states.
Step 1: Find Your Specific IRS Fax Number
The IRS uses two main processing centers for S-Corp elections. Using the wrong one won't just slow things down—it might lead to a rejection. For a complete list of IRS fax numbers for other forms, check our IRS Fax Numbers Guide.
