Late S Corp election: how Rev. Proc. 2013-30 relief works (2026 guide)

The IRS officially gives you 2 months and 15 days after the start of a tax year to elect S Corporation status. For a calendar-year business, that's March 15 of the year you want the election to take effect.

If you missed that, take a breath. You're not stuck paying full self-employment tax for the whole year. A 2013 IRS revenue procedure — Rev. Proc. 2013-30 — gives you a 3-year-and-75-day window to file a late election with reasonable cause and get the same tax treatment as if you'd filed on time.

This article walks through exactly what relief you qualify for, what you have to attach to Form 2553 to claim it, and what the IRS will check.

The headline rules

You can file a late S Corp election up to 3 years and 75 days after your intended effective date as long as you can show:

1. The corporation intended to be classified as an S Corp from the original effective date
2. The election would have been valid if filed on time
3. The reason it wasn't filed was reasonable cause (not willful neglect)
4. All shareholders have treated themselves consistently with S Corp status (or no return has been filed yet)

If all four are true, the IRS grants relief automatically — no private letter ruling required, no IRS approval needed in advance. You just attach a Section I narrative statement to Form 2553 and submit it.

What "reasonable cause" actually means

Rev. Proc. 2013-30 doesn't define a specific list of acceptable reasons. In practice, the three the IRS routinely accepts are:

1. Reliance on a tax professional

"I hired a CPA / tax preparer / attorney to handle my S Corp election. They didn't file Form 2553 on time."

By far the most common — and the IRS rarely pushes back on it. The professional's name and the nature of your engagement should appear in your narrative.

2. Administrative oversight or inadvertent error

"I knew I needed to file but missed the deadline due to an administrative oversight."

Less commonly accepted than #1 but still works. The narrative should explain what specifically slipped (e.g., "incorporation paperwork was filed Q4 and the S Corp election deadline fell during a holiday period").

3. Lack of awareness or misunderstanding of the deadline

"I incorporated and didn't know there was a separate election form to file."

This is the trickiest one. It works for first-time founders, less so for established business owners. The narrative needs to be specific about why you didn't know.

You can also pick a secondary reason ("Recent discovery of the failure to timely file") if applicable — this kicks in when you only just learned about Form 2553 and corrective action followed within a reasonable time.

What the IRS will verify (Section 4.02 conditions)

Before granting relief, the IRS asks one specific question on Form 2553's late-election narrative:

"How were prior tax returns filed for the affected year(s)?"

Your answer determines the consistency check under §4.02(2) of the Rev. Proc. There are five possible answers:

If you've already filed a C Corp return for the year you're trying to retroactively elect, you can't use Rev. Proc. 2013-30. Your only path is to elect S Corp status going forward (next tax year) instead.

The Section I narrative statement (auto-assembled)

When you check "Yes, late election" on Form 2553, you have to attach a written explanation that includes:

1. The intended effective date of the election
2. The reason for the late filing (your primary cause)
3. The §4.02(2) consistency representation (which prior-return scenario above applies)
4. A statement that you took corrective action upon discovering the error
5. A request for relief under Rev. Proc. 2013-30
6. A signed perjury attestation

It's typically 4-6 paragraphs. We auto-assemble this paragraph by paragraph from your answers — you never have to draft the IRS-required language by hand. The live preview shows you the exact text that will land on Form 2553 Section I before you sign.

A typical narrative reads like:

The corporation intended to elect to be treated as an S Corporation effective [date]. The failure to timely file Form 2553 was due to reliance on a tax professional who did not timely file the election. The failure was not due to willful neglect.

The corporation has not yet filed its federal income tax return for the first year in which the election was intended to be effective.

Upon discovery of the error, the corporation took immediate corrective action by filing this election.

The corporation meets all applicable requirements for relief under Revenue Procedure 2013-30 and respectfully requests acceptance of its late S Corporation election.

What about the IRS fee?

There is no IRS fee for filing a late election under Rev. Proc. 2013-30. The relief is automatic when conditions are met. You only pay if you have to fall back to the more formal private letter ruling route (Rev. Proc. 2003-43 / 9100 relief), which costs $12,600 and is reserved for cases that don't fit the Rev. Proc. 2013-30 conditions.

99% of late filings qualify for the automatic relief. We've never had a customer need a PLR.

When the late-filing window closes

For a tax year starting January 1, 2026:

• On-time deadline: March 15, 2026
• Late-filing window closes: March 15, 2029 (3 years and 75 days after Jan 1, 2026)

For a fiscal year that started June 15, 2025:

• On-time deadline: August 30, 2025
• Late-filing window closes: August 29, 2028

We auto-detect both windows from your effective date when you fill out our intake form — you don't have to do the math.

What if I'm past the 3-year-75-day window?

Your remaining options:

1. Elect S Corp going forward. File Form 2553 for the next tax year (on time this time). You forfeit the missed years' tax savings but get clean S Corp status from then on.
2. Apply for 9100 relief under Rev. Proc. 2003-43. Requires a private letter ruling, $12,600 IRS fee, and a strong demonstration of reasonable cause + good faith. Only practical for high-tax-savings situations where the missed years are worth the fee.

Common mistakes that void late relief

• Filing Form 2553 by itself without the Section I narrative. The IRS will reject this — you must attach the explanation when checking the late-election box.
• Missing the perjury attestation. The narrative requires "Under penalties of perjury…" language and an officer signature. Without it, the IRS treats it as an incomplete filing.
• Inconsistent shareholder treatment. If one shareholder filed a C Corp return for the affected year and another reported the income on Schedule C, you don't pass the consistency check.
• Filing >3 years 75 days late. The Rev. Proc. 2013-30 window is hard. After it closes, you're stuck with the 9100-relief route or going forward only.
