Most business owners assume they have until tax day to decide how their company gets taxed. That assumption quietly costs them thousands. Knowing exactly when is s corps election considered late is the difference between keeping your self-employment tax savings and handing the IRS money you never had to pay. The good news is that a late election is rarely fatal. The IRS built a generous relief path most owners do not even know exists.

This guide breaks down the real deadline, what the IRS considers late, the relief rules under Revenue Procedure 2013-30, and the step-by-step way to fix a missed election without penalties. We will use plain English, real dollar figures, and specific IRS forms so you can act today.

Quick Answer: When Is an S Corp Election Considered Late?

An S Corp election is considered late when Form 2553 is filed after the 15th day of the third month of the tax year you want the election to take effect. For a calendar-year business, that deadline is March 15. File it on March 16 or later and the IRS treats your election as late, meaning it will not apply until the following tax year unless you qualify for relief.

Here is the number that matters: the deadline is two months and 15 days after the start of your tax year. For a business that started on June 1, 2026, the deadline would be August 15, 2026. Miss that window and you are in late-election territory. The term when is s corps election considered late comes up constantly because the two-month-and-fifteen-day rule confuses almost everyone.

What an S Corp Election Actually Is (In Plain English)

An S Corp is not a type of business entity. It is a tax election. You still operate as an LLC or a corporation, but you ask the IRS to tax the business under Subchapter S of the tax code. In plain English: it is a tax status you apply for by filing Form 2553, Election by a Small Business Corporation.

Why do owners want it? Because an S Corp lets you split your business profit into two buckets: a reasonable salary (subject to payroll taxes) and distributions (not subject to self-employment tax). That split is where the savings live.

The Self-Employment Tax Problem the Election Solves

A single-member LLC taxed as a sole proprietorship pays 15.3 percent self-employment tax on every dollar of net profit, up to the Social Security wage base, then 2.9 percent Medicare on the rest. On $120,000 of profit, that is roughly $17,000 in self-employment tax alone before income tax even enters the picture.

With an S Corp election, you might pay yourself a $70,000 reasonable salary and take $50,000 as a distribution. The 15.3 percent payroll tax applies only to the salary. That single move can save $7,000 to $8,000 per year. Many business owners never learn this until they have already overpaid for years.

Key Takeaway: The S Corp election itself is free to file, but missing the deadline can cost you a full year of self-employment tax savings, often $7,000 or more.

The Exact Deadlines That Make an Election Late

There are two deadline scenarios, and most confusion comes from mixing them up.

Scenario 1: Existing Business Electing for the Current Year

If your business already exists and operates on a calendar year, you must file Form 2553 no later than March 15 of the year you want S Corp treatment to begin. File by March 15, 2026, and your election applies to all of 2026. File on March 16, 2026, and absent relief, the IRS pushes your election to 2027.

Scenario 2: Newly Formed Business

A brand-new entity has two months and 15 days from its formation date or the start of its first tax year. If you form your LLC on September 10, 2026, count forward two months to November 10, then add 15 days: your deadline is roughly November 25, 2026.

Why the “Two Months and 15 Days” Rule Trips People Up

People assume the deadline is simply 75 days. It is not. The IRS counts two full calendar months first, then adds 15 days. Depending on the month lengths involved, that can be more or fewer than 75 actual days. Always count months first, then add 15 days, exactly as the IRS instructions for Form 2553 describe.

What the IRS Considers Late and What Happens Next

Once you pass the deadline, your Form 2553 is a late election. By default, the IRS will not apply your election to the year you wanted. Instead, it bumps to the next tax year. That means another full year as a sole proprietor or C Corp, another full year of self-employment tax, and the frustration of knowing you missed the window by days.

But here is what the IRS does not advertise loudly: there is a well-established relief procedure. If you meet a handful of conditions, you can file a late election and have it treated as if it were timely. This relief is spelled out in IRS Form 2553 instructions and Revenue Procedure 2013-30.

How to Fix a Late S Corp Election With IRS Relief

Revenue Procedure 2013-30 is the lifeline. It allows a business to file Form 2553 up to 3 years and 75 days after the intended effective date and still get the election approved retroactively, provided you meet the requirements.

The Conditions You Must Meet for Relief

• The entity intended to be classified as an S Corp as of the intended effective date.
• The only reason the election was not timely is the failure to file Form 2553 on time.
• The business has reasonable cause for the late filing (a simple, honest explanation works).
• The business has consistently filed returns as if the S Corp election were in place, or has not yet filed its first return.
• Less than 3 years and 75 days have passed since the intended effective date.

Step-by-Step: How to File a Late Election

1. Download the current Form 2553 from IRS.gov. Do not use an old version.
2. Complete all shareholder information exactly as it appears on your formation documents.
3. Enter your intended effective date in Part I, line E. This is the date you wanted S Corp status to begin.
4. Write the magic phrase at the top of the form: “FILED PURSUANT TO REV. PROC. 2013-30.”
5. Attach a reasonable cause statement explaining why the election was late. Keep it honest and brief.
6. Have every shareholder sign. Missing signatures are the single most common reason relief is denied.
7. Mail it to the correct IRS service center listed in the Form 2553 instructions for your state.

Our entity formation services handle this exact process for owners who want it done right the first time, including the reasonable cause statement and service center routing.

Pro Tip: You can file a late Form 2553 attached to your first S Corp tax return (Form 1120-S) if you have not yet filed for that year. This bundles the election and the return in one envelope.

KDA Case Study: Freelance Consultant Recovers a Missed Deadline

Marcus, a 1099 marketing consultant in California, formed his single-member LLC in January 2025 and earned $140,000 in net profit that year. He meant to become an S Corp but got busy with client work and never filed Form 2553. By the time he came to KDA in early 2026, the March 15, 2025 deadline was long gone, and he had paid roughly $19,000 in self-employment tax for 2025.

We reviewed his situation and confirmed he qualified for relief under Revenue Procedure 2013-30. He had reasonable cause, had not filed his 2025 return yet, and was well within the 3-year-and-75-day window. We prepared a late Form 2553 with the proper relief language, drafted his reasonable cause statement, and filed it alongside his first Form 1120-S. We set his effective date to January 1, 2025, making the election retroactive.

The result: Marcus’s 2025 profit was restructured into a $85,000 reasonable salary and $55,000 in distributions. That shifted roughly $55,000 out of self-employment tax territory, saving him about $8,400 for the year. He paid $3,200 for the full engagement, a 2.6x first-year return, and he is now positioned to save a similar amount every year going forward.

Common Mistakes That Make a Late Election Even Worse

Filing late is fixable. These mistakes are what turn a recoverable situation into a denied election.

Red Flag Alert: Inconsistent Tax Reporting

If you claim you intended to be an S Corp since January but you already filed a Schedule C for that year as a sole proprietor, you have created a contradiction. Relief requires consistency. File the way you intend to be treated, or hold the return until the election is sorted.

Missing Shareholder Signatures

Every shareholder, and for married couples in community property states often a spouse, must sign Form 2553. The IRS rejects incomplete forms outright, and by the time you learn of the rejection, your relief window may have narrowed.

Waiting Past the Three-Year-and-75-Day Limit

The relief procedure is generous but not unlimited. Once you cross 3 years and 75 days past the intended effective date, the simplified relief is gone and you are left with a far more expensive private letter ruling request. Do not let time run out.

What If I Already Missed This Year’s Deadline?

You have two realistic paths. First, file a late election under Revenue Procedure 2013-30 with an effective date for the current year, assuming you qualify and have not filed inconsistently. Second, if relief is not available, file a timely election for the next tax year so you at least lock in savings going forward. The worst choice is doing nothing, because every month of inaction is self-employment tax you will never recover.

Do I Need to Run Payroll Immediately After Electing?

Yes, and this is where many new S Corp owners stumble. Once the election is effective, you must pay yourself a reasonable salary through formal payroll with proper withholding. The IRS scrutinizes S Corp owners who take all distributions and zero salary. A reasonable salary tied to your role, industry, and hours worked keeps you compliant and protects the distribution savings.

How Much Can I Realistically Save?

Savings scale with profit. A rough rule of thumb: for every $10,000 you move from salary into distributions, you save about $1,530 in payroll tax, up to the Social Security wage base. On $100,000 of profit with a $60,000 salary, you keep around $6,000 in annual savings. The election is one of the highest-return moves available to profitable small businesses, which is why nailing the deadline matters so much.

Frequently Asked Questions

Can I file Form 2553 at any time during the year?

You can file it any time, but timing controls which year it takes effect. File within two months and 15 days of your tax year start for current-year treatment. File after that and it is late, requiring relief or deferral to next year.

Does California have its own S Corp election?

California generally recognizes the federal S Corp election automatically, but S Corps in California still pay a 1.5 percent franchise tax on net income with an $800 annual minimum. Factor this in when weighing the election, and confirm current rules with the Franchise Tax Board.

What is reasonable cause for a late filing?

Reasonable cause can be as simple as not knowing the deadline, relying on an advisor who failed to file, or administrative oversight during business formation. The IRS accepts honest, plausible explanations for most late elections under Revenue Procedure 2013-30.
