IRS Penalties Can Be Reversed—If You Know What to Do


If you’ve been hit with IRS penalties for late filing, late payment, or underpayment, you’re not alone. These charges can stack up quickly—often adding thousands of dollars to your tax bill. The good news? You may not have to pay them.


The IRS offers several ways to request penalty abatement or challenge penalties through the appeals process—but it requires the right timing, documentation, and strategy.


In this post, we break down the most common types of IRS penalties, who qualifies for relief, and how to request an abatement or appeal a denial.


The Most Common IRS Penalties

  • Failure to File Penalty – 5% of unpaid tax per month (up to 25%)
  • Failure to Pay Penalty – 0.5% of unpaid tax per month (up to 25%)
  • Estimated Tax Penalty – For not making adequate quarterly payments
  • Accuracy-Related Penalty – 20% for substantial understatement or negligence
  • Trust Fund Recovery Penalty – Serious consequences for payroll tax violations


These penalties accrue on top of interest and can dramatically increase your total IRS balance.

Option 1: Request Penalty Abatement for Reasonable Cause

If you had a legitimate reason for falling behind, you may qualify for IRS penalty abatement under the “reasonable cause” standard.


Accepted reasons include:

  • Serious illness or injury
  • Death in the immediate family
  • Fire, flood, or natural disaster
  • Theft or loss of records
  • Reliance on incorrect advice from a tax professional


You must demonstrate that the issue was beyond your control and that you acted responsibly once the issue was resolved.

Option 2: First-Time Penalty Abatement (FTA)


If this is your first penalty in the past three years, and you're otherwise compliant, you may qualify for automatic penalty relief under the First-Time Abatement policy.


FTA can apply to:

  • Failure to File
  • Failure to Pay
  • Failure to Deposit (for businesses)


FTA is easier to request and doesn’t require supporting documentation—just eligibility confirmation.

Option 3: Appeal the Penalty


If the IRS rejects your abatement request, you can:

  • Submit a formal appeal to the IRS Independent Office of Appeals
  • Use Form 843 or include a detailed letter outlining your case
  • Strengthen your defense by filing an appeal through a CDP hearing if the penalty is tied to enforced collections

Appeals give you an opportunity to present evidence and argue that the penalty was unjust or misapplied.


How to Submit a Penalty Abatement Request


Step 1: Gather documentation
Medical records, disaster reports, legal filings, proof of advice relied on, etc.


Step 2: File the right forms

Use Form 843 or include a letter with your response to the IRS notice


Step 3: Submit to the correct IRS office
This is typically the address on the penalty notice (CP504, CP15, etc.)


Step 4: Follow up and track your transcripts

Don’t ignore the penalty—many cases are denied simply because the taxpayer never asked.

Frequently Asked Questions

What types of IRS penalties can be challenged?

Common penalties include late filing, late payment, underpayment of estimated tax, and accuracy-related penalties. Many of these can be reduced or removed if you qualify.

What is penalty abatement?

Penalty abatement is the process of asking the IRS to remove or reduce penalties due to reasonable cause, first-time abatement, or IRS error.

How does first-time penalty abatement work?

If you have a clean compliance history, you may qualify for first-time abatement. This relief is available for certain penalties like failure-to-file or failure-to-pay.

What is “reasonable cause” for penalty relief?

Reasonable cause can include illness, natural disasters, reliance on incorrect advice, or other circumstances outside your control that prevented timely compliance.

Can I appeal an IRS penalty if abatement is denied?

Yes. If your request is denied, you can appeal through the IRS Office of Appeals, which independently reviews disputes.

Do penalties keep accruing interest?

Yes. Penalties accrue interest until the underlying balance is resolved. Getting penalties abated reduces future interest accruals as well.

Does penalty relief apply to businesses?

Yes. Businesses, like individuals, can request penalty abatement or appeal if they can show reasonable cause or qualify for first-time relief.

Should I hire a professional for penalty relief?

Yes. Professionals know how to frame reasonable cause requests, gather documentation, and navigate the appeals process effectively.
