Reasonable Cause Relief for a Late S-Corp or Entity Election

If you missed the deadline to elect S-corporation status, you can still get reasonable cause relief for a late S-corp election under Revenue Procedure 2013-30, provided you act within three years and 75 days of the date the election was supposed to take effect. There is no user fee, and you don’t need a private letter ruling. What you do need is a legitimate reason for the delay and proof that your business has been filing taxes as if the election were already in place.1Internal Revenue Service. Late Election Relief

Do You Qualify for Simplified Relief

Rev. Proc. 2013-30 sets four conditions, and you have to meet all of them.2Internal Revenue Service. Revenue Procedure 2013-30 – Section 4.02

  • The entity intended to be an S-corporation as of the date the election should have taken effect.
  • The only reason it wasn’t treated as one is that Form 2553 wasn’t filed on time.
  • The entity and every shareholder have filed all federal returns consistent with S-corp status for every year affected by the missed election.
  • There is reasonable cause for the failure, and the entity acted diligently once it discovered the mistake.

The consistency requirement causes the most trouble. If the corporation filed a Form 1120 (the C-corporation return) for any year in the window, the chain is broken and simplified relief is off the table. Every shareholder who held stock at any point between the intended effective date and the filing date must have reported income as though the S-corp election existed.3Internal Revenue Service. Revenue Procedure 2013-30 – Section 5.02

The entity also has to actually qualify as an S-corporation: a domestic corporation with 100 or fewer shareholders, only individuals, estates, and certain trusts as owners, and a single class of stock.4Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined If you have a nonresident alien shareholder or preferred stock, no reasonable cause argument will save the election.

What Reasonable Cause Actually Means

Reasonable cause means you exercised ordinary business care and prudence but still couldn’t meet the deadline. The IRS evaluates each request on its own facts, and the question isn’t whether you were perfect — it’s whether the failure is understandable rather than a calculated bet.5Internal Revenue Service. Penalty Relief for Reasonable Cause

Reliance on a Tax Professional

This is the strongest argument available, and it works better here than in most penalty contexts. For general late-filing penalties, the IRS generally holds that you can’t delegate your tax obligations and then blame the advisor.6Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief – Section 20.1.1.3.2.2.5 For late elections, the regulations take a different view: a taxpayer who reasonably relied on a qualified professional who then failed to file or advise filing the election has acted in good faith.7Internal Revenue Service. Revenue Procedure 2013-30 – Section 301.9100-3(b)(1)(v)

To use this ground effectively, explain that you gave the professional the information they needed, that filing the election was within the scope of their engagement, and when you learned it hadn’t been done. An engagement letter or email trail helps.

Other Grounds the IRS Accepts

Death, serious illness, or unavoidable absence of the person solely responsible for the entity’s tax compliance qualifies, particularly for small businesses where one person handles everything. A first-time business owner who genuinely didn’t know about the election deadline may qualify, especially when combined with other factors; ignorance on its own is weak but the IRS weighs it against the full picture.8Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief – Section 20.1.1.3.2.2.6 Natural disasters, fires, and system failures at your accounting firm count when documented with dates.

Writing the Statement

The IRS wants two things in your narrative: what prevented timely filing, and what you did once you caught the mistake. The explanation has to connect the specific cause to the exact period when filing was due.9Internal Revenue Service. IRM 20.1.1 Introduction and Penalty Relief – Section 20.1.1.3.2.2.4 “We didn’t get around to it” won’t do. “Our CPA left the firm in February 2024 and the replacement discovered the unfiled Form 2553 during onboarding in June 2024, at which point we filed within two weeks” tells a story the IRS can evaluate.

Prompt action matters. The longer the gap between discovering the error and filing for relief, the harder reasonable cause becomes. Finding out in January and waiting until November invites questions you won’t want to answer.

Your statement should cover:

  • Who was responsible for filing the election
  • The events that caused the delay, with dates
  • When and how you discovered the error
  • What corrective steps you took and when
  • Confirmation that the entity and all shareholders have filed returns consistent with S-corp status for every affected year

An authorized officer of the corporation must sign the statement under penalties of perjury. It is the primary evidence the IRS uses to decide your case.10Internal Revenue Service. Revenue Procedure 2013-30 – Section 4.03

How to File the Late Election

Complete Form 2553 with the entity’s legal name, address, and EIN. Enter the exact date the election should have taken effect. Every shareholder who held stock at any point between that date and the filing date must sign — a missing signature will get the request returned.3Internal Revenue Service. Revenue Procedure 2013-30 – Section 5.02

Write “FILED PURSUANT TO REV. PROC. 2013-30” across the top of Form 2553. That notation routes your request into the simplified late-relief track instead of a standard late filing or the private letter ruling process. If you’re attaching the form to a Form 1120-S, write “INCLUDES LATE ELECTION(S) FILED PURSUANT TO REV. PROC. 2013-30” in the top margin of the first page of the 1120-S.11Internal Revenue Service. Instructions for Form 2553

You have three ways to submit:

  • Mail the original form (not a photocopy) to the IRS Service Center for your area — Kansas City, MO or Ogden, UT, depending on where your principal business is located.12Internal Revenue Service. Where to File Your Taxes for Form 2553
  • Fax it to 855-887-7734 (Kansas City) or 855-214-7520 (Ogden).
  • Attach it to the entity’s current-year Form 1120-S, so long as all prior-year 1120-S returns have already been filed.

Form 2553 cannot be filed electronically.11Internal Revenue Service. Instructions for Form 2553

What Happens After You File

Expect a response in roughly 60 days.11Internal Revenue Service. Instructions for Form 2553 Approval comes as a CP261 notice, the official S-corporation acceptance letter that confirms the effective date.13Internal Revenue Service. Understanding Your CP261 Notice Keep it permanently. You may need it years later during audits or with state tax agencies that rely on the federal election.

If Relief Is Denied

A denial means the IRS treats the entity under its default classification for every year the election was supposed to be in place. For a state-law corporation, that default is C-corp status: a 21% corporate tax on profits, then another layer of tax on dividends up to 20% plus the 3.8% net investment income tax for higher earners.14Internal Revenue Service. S Corporations

Penalties compound the tax hit. If the entity filed Forms 1120-S without a valid election, those returns are treated as delinquent or incomplete. For returns required in 2026, the penalty runs $255 per shareholder per month (or partial month), up to 12 months.15Internal Revenue Service. Instructions for Form 1120-S A five-shareholder company that’s 12 months late faces up to $15,300 on a single return, multiplied across every affected year. Shareholders would then need to amend personal returns to remove pass-through income and, if distributions were made, report dividends instead.

If You’re Past the Three-Year Window

Once more than three years and 75 days have passed since the intended effective date, Rev. Proc. 2013-30 is no longer available. The remaining route is a private letter ruling under Treasury Regulation § 301.9100-3, which carries a $14,500 user fee and can take several months to over a year.1Internal Revenue Service. Late Election Relief16Internal Revenue Service. Internal Revenue Bulletin 2026-1 You still have to show reasonable cause and good faith, and the IRS also weighs whether granting relief would prejudice the government’s interests.

A separate simplified path, Revenue Procedure 2009-41, covers late Form 8832 entity classification elections rather than late S-corp elections. It uses the same three-year-and-75-day window and charges no fee.17Internal Revenue Service. Revenue Procedure 2009-41 If an LLC intended to be taxed as an S-corp but never filed Form 8832 to be treated as a corporation first, the fix may require both a late Form 8832 and a late Form 2553, filed together.
