The IRS accepts a handful of recurring reasonable cause explanations for a late Form 2553 filing: reliance on a tax professional who dropped the ball, the death or serious illness of the person responsible for the filing, an honest misunderstanding by an inexperienced owner about what the election required, a natural disaster that physically disrupted the business, and IRS errors such as a lost form or incorrect guidance from an agent. What ties the accepted reasons together is that the corporation tried to comply and was tripped up by something outside ordinary neglect. Below are the categories that work, the ones that don’t, and what each explanation needs to look like on paper.
Late-election relief sits under Revenue Procedure 2013-30, the streamlined process for granting retroactive S status when a corporation misses the normal deadline of two months and 15 days after the start of the tax year.1Internal Revenue Service. Late Election Relief The IRS evaluates each request based on whether the corporation exercised ordinary business care and prudence but still failed to file on time.2Internal Revenue Service. Reasonable Cause and Good Faith
Reasonable Cause Reasons the IRS Accepts
Reliance on a Tax Professional
This is the most common winning argument. A corporation hires a CPA or tax attorney, hands over all the information about the business and its shareholders, and the professional either forgets to file Form 2553, files it late, or incorrectly tells the client no filing is needed. The corporation reasonably believed the election was handled.
For the argument to carry weight, the reliance has to be objectively reasonable. The IRS looks at whether the advisor had the relevant expertise and whether the corporation gave the advisor complete information.2Internal Revenue Service. Reasonable Cause and Good Faith A signed statement from the professional admitting the error is powerful evidence. If the corporation never specifically asked about the S election, or never gave the advisor the shareholder details needed to complete the form, the argument falls apart.
Death, Serious Illness, or Incapacity
When the person responsible for the corporation’s tax filings dies, becomes seriously ill, or is otherwise incapacitated during the filing window, the IRS regularly grants relief. The key individual might be the sole owner, an officer who handles compliance, or an outside accountant the business depended on exclusively.
Documentation needs to be concrete: a death certificate, a physician’s letter confirming the diagnosis and the period of incapacity, or hospital records showing the timing. The connection between the person’s inability to act and the missed deadline must be clear. A shareholder’s minor illness that didn’t actually prevent anyone from filing won’t qualify.
Honest Mistakes About What Was Required
New business owners frequently assume the S election happens automatically when they form their corporation or LLC. Others confuse their state formation filing with the federal election, or believe their incorporation attorney or online formation service handled it. These genuine misunderstandings can satisfy reasonable cause when the taxpayer acted in good faith and took at least some steps toward compliance.
The IRS considers the taxpayer’s experience, education, and sophistication with tax matters when weighing this kind of claim.2Internal Revenue Service. Reasonable Cause and Good Faith A first-time owner with no tax background who thought the online formation service filed the election stands on much stronger ground than a serial entrepreneur who has formed S corporations before. The reasonable cause statement should explain exactly what the taxpayer believed, why that belief was reasonable in context, and what they did once they discovered the error.
Natural Disasters
Fires, floods, hurricanes, and other events that physically prevent access to records or the ability to communicate with a tax professional are accepted grounds. The disaster has to have occurred close enough to the deadline to directly block the filing. A hurricane that hit six months before the deadline expired is harder to connect than one that struck the week before.
Documentation for disaster-related claims is often publicly available through FEMA declarations. The reasonable cause statement should show that the business was in the affected area and explain how the disaster specifically disrupted the filing, whether through lost records, displaced employees, or inability to reach the accountant.
IRS Errors or Lost Filings
Sometimes the corporation did everything right and the IRS lost the form or failed to process it. Other times, an IRS employee gave the taxpayer incorrect advice about the deadline or requirements. Both situations meet the reasonable cause standard.
The strongest evidence for a lost filing is a certified mail receipt showing timely submission. For incorrect IRS advice, written records carry far more weight than a recollection of a phone call. If the corporation relied on oral guidance from the IRS, the statement should include the date of the call, the employee’s name or ID number, and the specific advice given.
Reasons That Don’t Count
Understanding what the IRS rejects can save a corporation from building a case around a losing argument. Several common explanations generally fail on their own.3Internal Revenue Service. Penalty Relief for Reasonable Cause
- Simply not knowing about the requirement. Ignorance of the filing deadline, without more, is not reasonable cause. The IRS expects taxpayers to learn their obligations or hire someone who knows.
- Delegating without any follow-up. Telling an accountant to “handle everything” and never confirming that the S election was filed can undercut a reliance argument. The taxpayer is expected to take some responsibility for verifying critical filings.
- Choosing to delay. Deciding to wait and file later because you weren’t sure S status was the right choice is a business decision, not reasonable cause.
- Ordinary administrative oversights. A form sitting on someone’s desk or an unread email doesn’t automatically qualify. The IRS may still grant relief if the oversight is paired with circumstances showing the corporation genuinely tried to comply, but “we forgot” rarely succeeds on its own.
The common thread across denials is willful neglect or a lack of effort. The IRS draws a sharp line between taxpayers who tried and failed and those who simply didn’t prioritize compliance.
Writing a Reasonable Cause Statement That Works
The reasonable cause statement is a signed narrative, submitted under penalties of perjury, explaining exactly why the election wasn’t filed on time. Generic explanations get generic denials. Specifics matter: dates, names, what went wrong, and when the error was discovered.
A workable statement typically covers four things. First, the intended effective date of the election and the deadline that was missed. Second, the specific chain of events that caused the failure, with real dates and the people involved. Third, what the corporation did once it discovered the problem and how quickly. Fourth, the supporting documentation attached to the request, whether that’s an engagement letter with the accountant, medical records, a FEMA declaration, a certified mail receipt, or a signed statement from the professional who made the mistake.
Form 2553 itself should be filled out completely, including Item E (the intended effective date), with “Filed Pursuant to Rev. Proc. 2013-30” written across the top margin of page one.4Internal Revenue Service. Filing Requirements for Filing Status Change Every person who was a shareholder at any point between the intended effective date and the filing date must sign a statement confirming they reported their income consistently with S corporation status for all affected years.5Internal Revenue Service. Revenue Procedure 2013-30
Prerequisites the Reasonable Cause Argument Can’t Fix
Reasonable cause only matters if the corporation clears a few threshold requirements first. Even the strongest explanation won’t rescue a filing that fails on these points.
The corporation must satisfy every structural requirement for S eligibility under Internal Revenue Code Section 1361 for the entire period it wants the election to cover: no more than 100 shareholders, no shareholders who are nonresident aliens or ineligible entities, and only one class of stock.6Office of the Law Revision Counsel. 26 U.S. Code 1361 – S Corporation Defined If any of those tests was failed during the relevant period, streamlined late-election relief isn’t available.
The corporation and all shareholders must also have reported income consistently with S corporation status for every year since the intended effective date, meaning Form 1120-S returns and Schedule K-1s to shareholders, with each shareholder picking up their share on their personal returns.5Internal Revenue Service. Revenue Procedure 2013-30 If the corporation filed a C corporation Form 1120 for any year in question, the streamlined path is closed.
Finally, timing. The standard track requires submitting the request within three years and 75 days of the intended effective date.1Internal Revenue Service. Late Election Relief A valuable exception exists for corporations that have always filed as S corporations, always reported consistently, and were never contacted by the IRS about any S election problem within six months of filing their first 1120-S; those corporations are not bound by the three-year-and-75-day clock.5Internal Revenue Service. Revenue Procedure 2013-30 That exception often saves businesses that discover years later their accountant never actually filed the Form 2553.
