Missing the Form 2553 deadline can disqualify your business from S corporation taxation. That mistake can change how your income is taxed, increase self employment tax exposure, and create retroactive correction work. This guide explains exactly when Form 2553 is due, how to file correctly, and what to do if you miss the deadline.
What Form 2553 Actually Does
Form 2553 is filed with the Internal Revenue Service to elect S corporation status. Without approval of this election, your business remains taxed as:
• A C corporation if you formed a corporation
• A default partnership if you formed a multi member LLC
• A disregarded entity if you formed a single member LLC
S corporation status allows income to pass through to shareholders while potentially reducing self employment taxes through structured payroll.
The Core Deadline Rule
The standard rule is strict.
To be effective for a specific tax year, Form 2553 must be filed:
Within 2 months and 15 days after the beginning of the tax year in which the election is to take effect.
For a calendar year business wanting S corporation status for 2026:
• The deadline is March 16, 2026
March 15 falls on a Sunday in 2026, so the deadline shifts to the next business day.
If your business was newly formed in 2026 and wants S status starting from formation, the 2 months and 15 days rule applies from the date of formation.
Example
If your company was formed on January 10, 2026, your Form 2553 must be filed by March 25, 2026.
Late Election Relief Is Possible But Not Automatic
If you miss the deadline, the IRS may grant late election relief. However, you must prove:
• You intended to be taxed as an S corporation
• You acted reasonably and in good faith
• You have reasonable cause for the delay
You must also attach a late election statement explaining the failure.
Late relief is common but not guaranteed. Waiting increases audit risk and processing delays.
Eligibility Requirements You Must Confirm
Before filing Form 2553, verify that your company qualifies.
Your business must:
• Be a domestic corporation or eligible LLC
• Have 100 or fewer shareholders
• Have only eligible shareholders such as individuals, certain trusts, and estates
• Have only one class of stock
• Not be an ineligible corporation such as certain financial institutions or insurance companies
Every shareholder must sign and consent to the election.
One missing signature can invalidate the election.
How to File Form 2553 Properly
The IRS currently requires Form 2553 to be mailed or faxed to the appropriate service center. Electronic filing is limited.
Steps:
- Complete all entity information including EIN and formation date
- Confirm the effective date of election
- Obtain signatures from all shareholders
- Send via certified mail or approved fax
- Retain delivery confirmation
Many new owners delay their EIN and get stuck at the banking stage.

Do not assume approval is automatic. The IRS sends a formal acceptance letter. If you do not receive confirmation within 60 days, follow up immediately.
Coordination With Form 8832
If your LLC is not already classified as a corporation for tax purposes, you may need to file Form 8832 first to elect corporate taxation before filing Form 2553.
Many LLC owners skip this step and create classification errors.
Confirm your current tax classification before submitting Form 2553.
Strategic Timing Considerations for 2026
If you expect:
• Higher profits
• Increased payroll planning
• Reduced reliance on owner draws
• Outside investors
S corporation status may provide tax efficiency.
However, if your business has minimal profit or inconsistent cash flow, the payroll requirement may outweigh tax benefits.
Run projections before electing.
Payroll Setup Must Align With Election
Once S status is effective:
• Shareholder employees must be paid reasonable wages
• Payroll taxes must be filed quarterly
• W 2 forms must be issued annually
If payroll is not implemented properly, S corporation benefits collapse under audit.
You cannot take only distributions without wages.
Common Mistakes That Invalidate Elections
• Incorrect effective date
• Missing shareholder consent
• Filing after the deadline without explanation
• Not updating ownership changes
• Having multiple stock classes through profit distribution agreements
These errors create costly correction work.
What To Do If You Already Missed the Deadline
Act immediately.
Prepare:
• Completed Form 2553
• Late election relief statement
• Explanation of reasonable cause
• Signed shareholder consents
Submit with certified tracking and monitor response.
The sooner you file, the stronger your case for relief.
