What is Reasonable Cause for IRS Penalty Relief?
Reasonable cause penalty relief is possible—if you can prove good-faith compliance, documentation, and corrective action.
What is Reasonable Cause for IRS Penalty Relief?
Reasonable cause is a legal standard the IRS uses to determine whether a taxpayer (or business) should receive penalty relief when they failed to meet a tax requirement due to circumstances beyond their control. If the IRS agrees that your business acted in good faith and exercised ordinary business care, penalties may be reduced or removed.
Reasonable cause is commonly used when businesses request relief from penalties related to:
- late 1099 filing
- incorrect information returns
- IRS Notice 972CG penalties
- missing or incorrect TIN reporting
- late deposits or reporting issues
Reasonable cause does not mean “we forgot” or “we were busy.” It means there was a legitimate reason and you made a good-faith effort to comply.
Why Reasonable Cause Matters
IRS penalties can add up quickly because many penalties are assessed per form or per event. For businesses filing 1099s, even a small error rate can result in significant penalty exposure.
Reasonable cause is one of the most common ways businesses attempt to reduce penalties, especially after receiving:
IRS Notice 972CG
Reasonable cause is often your best path to penalty relief if you can show strong documentation and corrective action.
What Does the IRS Consider “Reasonable Cause”?
The IRS generally considers reasonable cause when:
- the business exercised ordinary business care and prudence
- the failure was due to circumstances beyond their control
- the business took corrective action as soon as possible
- the business did not intentionally disregard requirements
In most cases, the IRS will look at:
What happened?
Why did it happen?
What did you do to fix it?
What did you change to prevent it from happening again?
The IRS often cares as much about your corrective action as the original issue.
Common Examples of Reasonable Cause
Below are examples that may qualify as reasonable cause depending on the facts and documentation.
1. Natural Disasters or Severe Weather
Examples include:
- hurricanes
- floods
- wildfires
- severe storms
- major power outages caused by natural disasters
Disaster-related events are one of the most commonly accepted reasonable cause explanations.
2. Serious Illness or Death
Reasonable cause may apply if a key individual responsible for filing was affected by:
- serious illness
- hospitalization
- death in the immediate family
- unexpected incapacity
The IRS may consider this if it directly impacted your ability to file or respond on time.
3. Fire, Theft, or Destruction of Business Records
Examples include:
- fire destroying accounting records
- theft of computers or systems
- vandalism
- data loss due to unexpected physical damage
Loss of records can be considered reasonable cause if you can prove the event and show recovery efforts.
4. IRS System Issues or Filing Provider Outages
If your business attempted to file on time but could not due to:
- IRS system downtime
- electronic filing transmission failures
- software vendor outages
- filing provider platform errors
This may qualify if you can provide:
- system outage documentation
- proof of attempted submission
- filing confirmations and timestamps
Technology-related failures can support reasonable cause if properly documented.
5. Postal Delays (If Filing by Mail)
In certain cases, delays caused by:
- USPS disruption
- documented mailing issues
- mail processing delays
may support reasonable cause if you have:
- certified mail receipts
- mailing date proof
- tracking information
Mailing-related reasonable cause claims require clear evidence.
6. Incorrect Information Provided by Vendors (With Documentation)
For 1099 reporting, reasonable cause may apply if:
- the vendor provided incorrect EIN/SSN
- the vendor refused to provide a W-9
- the vendor delayed responding despite multiple outreach attempts
However, the IRS generally expects businesses to maintain proper documentation such as:
W-9 request records
vendor outreach emails
vendor response history
evidence of compliance process
Vendor-caused issues may help support reasonable cause, but only if you can prove you followed proper procedures.
Examples That Usually Do NOT Qualify as Reasonable Cause
Some reasons are commonly rejected by the IRS, including:
- forgetting the deadline
- being too busy
- staff turnover without proper planning
- lack of internal training
- not knowing the law
- poor internal organization
- lack of budget
- not having enough staff
The IRS generally does not accept “we didn’t know” or “we didn’t have time” as reasonable cause.
What Documentation Supports a Reasonable Cause Claim?
Reasonable cause requests are strongest when supported by documentation.
Examples include:
disaster reports or insurance claims
medical records (if applicable)
death certificates or obituary records
police reports (theft or vandalism)
system outage documentation
submission logs and timestamps
filing confirmations
vendor outreach logs and W-9 requests
corrective filing evidence
Documentation is what makes reasonable cause credible to the IRS.
How to Write a Reasonable Cause Letter (Best Practice)
A strong reasonable cause request should include:
- IRS notice reference (example: Notice 972CG)
- tax year involved
- summary of what happened
- why the failure occurred
- timeline of events
- documentation summary
- corrective actions taken
- steps taken to prevent recurrence
- request for penalty abatement
- contact information
IRS penalty relief requests should be factual, professional, and supported by evidence.
Reasonable Cause vs First-Time Abatement (FTA)
Some businesses confuse reasonable cause with First-Time Abatement.
They are different.
Reasonable Cause
- requires explanation and documentation
- based on circumstances beyond control
- evaluated case-by-case
First-Time Abatement (FTA)
- may apply if you have a clean compliance history
- does not require a major event or hardship
- depends on eligibility rules
Some businesses may qualify for FTA even if they do not have a strong reasonable cause argument.
Best Practices to Increase Approval Chances
To improve your chance of receiving penalty relief:
respond before the IRS deadline
provide a clear timeline of events
attach supporting documentation
show corrective filings were completed
show process improvements implemented
demonstrate good-faith compliance effort
The IRS is more likely to grant relief if you show the issue was corrected and controls were strengthened.
Common Reasonable Cause Scenarios for 1099 Penalties
For 1099-related penalties (such as Notice 972CG), reasonable cause requests often involve:
- late filing due to system outage or filing provider delay
- missing TIN due to vendor non-response
- incorrect TIN due to vendor-provided incorrect data
- corrected filings submitted as soon as issue discovered
- evidence of W-9 collection policies and compliance procedures
Reasonable cause is much stronger when your company has documented onboarding and validation processes.
Frequently Asked Questions (FAQ)
Does the IRS automatically approve reasonable cause requests?
No. The IRS reviews each request individually based on facts, documentation, and compliance history.
Is reasonable cause guaranteed if a vendor provided the wrong EIN?
Not necessarily. The IRS expects businesses to maintain documentation and follow proper outreach and compliance procedures.
Can reasonable cause remove all penalties?
It may. In some cases, penalties may be reduced rather than fully removed.
Should I file corrected 1099s before requesting penalty relief?
Often yes. Showing corrective action strengthens your request and demonstrates good-faith compliance.
How long does it take for the IRS to respond?
Response times vary. Businesses should keep copies of all correspondence and proof of delivery.
Conclusion
Reasonable cause is a standard the IRS uses to determine whether a business should receive penalty relief when compliance failures occurred due to circumstances beyond their control. Events such as natural disasters, serious illness, loss of records, system outages, or documented vendor noncompliance may support reasonable cause if the business acted responsibly and corrected the issue quickly. The strongest reasonable cause requests include clear timelines, strong documentation, and evidence of corrective action and process improvements.
