Reasonable cause penalty relief is available when circumstances beyond your control—such as illness, natural disasters, or reliance on bad advice—led to late filing, late payment, or deposit penalties. To apply, provide a written explanation with supporting documentation.
IRS penalties can be steep, but the agency recognizes that life events can make compliance impossible. If you can show that you exercised ordinary business care but still failed to meet obligations, you may qualify for reasonable cause penalty relief.

What is reasonable cause?
Reasonable cause means you made a good-faith effort to comply with tax obligations, but factors beyond your control prevented it. Unlike First-Time Abatement, which is based on clean history, reasonable cause requires proof of hardship or uncontrollable circumstances.
Common reasons accepted by the IRS
- Serious illness or death of the taxpayer or immediate family member
- Natural disasters (floods, fires, hurricanes)
- Records destroyed or inaccessible due to events outside your control
- Reliance on erroneous advice from a tax professional or the IRS
- Inability to obtain records necessary for filing
When reasonable cause does not apply
- Simple forgetfulness or negligence
- Lack of funds (unless tied to circumstances like disasters or illness)
- Failure to keep adequate records without extenuating circumstances
How to apply for reasonable cause penalty relief
Step 1: Confirm the penalty type
Reasonable cause may apply to failure-to-file, failure-to-pay, and failure-to-deposit penalties.
Step 2: Prepare your explanation
Clearly explain what prevented timely compliance and show that you acted in good faith.
Step 3: Provide documentation
- Hospital records, death certificates
- Insurance claims, FEMA reports
- Letters from tax professionals or IRS correspondence
Step 4: Submit your request
- Call the IRS to request relief (often works for small penalties).
- Send a written letter with supporting documentation.
- File Form 843 (Claim for Refund and Request for Abatement) when applicable.

Real-life scenarios
- Illness: A taxpayer hospitalized for several months missed the filing deadline. IRS granted penalty relief after receiving medical records.

Frequently Asked Questions
Is reasonable cause penalty relief automatic?
No. You must request it and provide documentation. The IRS decides case by case.
Can I get reasonable cause relief if I already had penalties before?
Yes. Unlike First-Time Abatement, prior penalties don’t disqualify you from reasonable cause relief.
Does lack of money qualify as reasonable cause?
Not by itself. But if inability to pay was tied to illness, disaster, or other uncontrollable events, the IRS may grant relief.
What’s the best way to request reasonable cause?
Call the IRS for smaller penalties, but for larger cases submit a written letter or Form 843 with evidence.
Does reasonable cause remove interest too?
No. Relief applies only to penalties. Interest continues until the tax is paid in full.
