How Long Does an S-Corp Election Take? (2026 Timeline)
The transition from an LLC to an S-Corp is not instantaneous. After you fax Form 2553, you enter a waiting period where your tax status is in limbo. Here is the exact timeline you can expect from the IRS.
Quick Answer
It takes the IRS approximately 60 days to process Form 2553 and mail you the official acceptance letter (Notice CP257A). If you file during peak tax season (January through April), processing can take 90 days or longer.
Key Points for 2026
- Standard Timeline: 60 days from the date of faxing.
- Peak Season Delays: Expect an extra 30-day delay if you file near the March 15 deadline.
- Retroactive Effect: The processing time does not change your tax status. If approved, you are an S-Corp retroactively back to the date you requested.
- No Expediting: You cannot pay a fee to process the election faster.
The S-Corp Election Timeline
Phase 1: Filing the Form (Day 1)
You print, sign, and fax Form 2553 to the IRS. Keep your fax confirmation sheet. At this moment, the IRS has received your form, but no human has looked at it.
Phase 2: The Waiting Period (Days 2–59)
Your form sits in the IRS processing queue. Do not call the IRS during this period. The agents answering the phones will not be able to see your form in the system until it has been fully processed.
Phase 3: Processing & Approval (Day 60)
An IRS clerk reviews your Form 2553. They verify that all shareholder signatures are present, that the LLC meets the eligibility requirements, and that the form was filed on time. If everything is correct, they update your EIN profile in the master database to reflect S-Corp status.
Phase 4: The Notice Arrives (Days 65–75)
The IRS automated system generates Notice CP257A and mails it via USPS to the business address on file. This is your official proof of election.
If 45 days pass and you haven't heard anything, do not fax the form again. Sending duplicate forms forces the IRS to manually merge your files, which pushes your application to the back of the queue and causes massive delays. Only resend the form if an IRS agent explicitly tells you to do so after 60 days have passed.
What to Do While You Wait
The biggest question business owners have is: "Do I run payroll while I'm waiting?"
If you wait 90 days to get approval, you will have missed an entire quarter of payroll. This will require you to run expensive "catch-up" payrolls and potentially incur late deposit penalties.
For this reason, most CPAs recommend acting like an S-Corp immediately. Set up your payroll provider, start taking a reasonable W-2 salary, and pay your payroll taxes. You operate under the assumption that the IRS will approve the election. If you filled the form out correctly and met the deadline, rejections are incredibly rare.
Example Scenario
The Situation: Mark forms an LLC on January 1st. He faxes Form 2553 on February 1st requesting an effective date of January 1st.
The Timeline: Mark sets up Gusto payroll in February and pays himself a salary. On April 5th (about 65 days later), Mark receives his CP257A letter in the mail. Because the election is retroactive to January 1st, the payroll he ran in February and March is perfectly legal and compliant.
What to Do Next
- Mark your calendar: Set a reminder for 60 days from the day you faxed the form.
- Start running payroll: Do not let the processing delay stop you from paying yourself a W-2 salary.
- Call if delayed: If 75 days pass and you have no letter, call the IRS Business line at 1-800-829-4933 to check the status.
