IRS Penalty Abatement: First-Time Abatement, Reasonable Cause, and How to Request Relief

IRS penalties can be devastating. A failure-to-file penalty of 5% per month, a failure-to-pay penalty of 0.5% per month, an accuracy-related penalty of 20% of the underpayment — these charges stack quickly and can add thousands or tens of thousands of dollars to your tax bill. But here’s what many taxpayers don’t know: the IRS regularly abates penalties when you qualify and make a proper request.

At The Law Office of Pietro Canestrelli, penalty abatement is one of the most common — and most impactful — services we provide for clients across Temecula, San Diego, Riverside, San Bernardino, and throughout California. In many cases, we reduce penalty assessments by 50-100%, saving our clients thousands of dollars. Here’s how the process works.

The Most Common IRS Penalties

Failure-to-File Penalty (IRC §6651(a)(1))

Assessed when you file your return after the due date (including extensions). The penalty is 5% of the unpaid tax per month, up to a maximum of 25%. For a $20,000 balance, the maximum failure-to-file penalty is $5,000.

Failure-to-Pay Penalty (IRC §6651(a)(2))

Assessed when you don’t pay your tax by the due date. The penalty is 0.5% of the unpaid balance per month, up to 25%. For a $20,000 balance, the annual failure-to-pay penalty is approximately $1,200.

Accuracy-Related Penalty (IRC §6662)

Assessed when the IRS determines you understated your tax due to negligence, disregard of rules, or a substantial understatement of income. The penalty is 20% of the underpayment. On a $50,000 understatement, that’s $10,000.

Estimated Tax Penalty (IRC §6654)

Assessed when you don’t pay enough estimated tax during the year. This penalty is calculated as interest on the underpayment for each quarter.

First-Time Abatement (FTA): The Low-Hanging Fruit

The IRS’s First-Time Abatement administrative waiver is the easiest penalty relief to obtain — and it’s chronically underutilized. Under FTA, the IRS will waive failure-to-file and failure-to-pay penalties for a single tax year if you meet three simple criteria:

• Clean compliance history: You filed all required returns and had no penalties assessed (or all penalties were abated) for the three tax years prior to the penalty year
• Current compliance: You’ve filed all currently required returns (or valid extensions)
• Payment arrangement: You’ve paid the tax due or arranged to pay through an installment agreement

That’s it. You don’t need to demonstrate reasonable cause. You don’t need to explain what happened. If you have a clean 3-year history, you’re entitled to FTA relief as a matter of IRS administrative policy (Internal Revenue Manual §20.1.1.3.6.1).

How to request FTA:

• By phone: Call the IRS at the number on your penalty notice and request First-Time Abatement. The representative can apply it immediately.
• In writing: Submit a written request citing IRM §20.1.1.3.6.1 and stating that you meet the eligibility criteria.
• Through a representative: Your tax attorney or enrolled agent can request FTA on your behalf through the Practitioner Priority Service line.

FTA can only be used for one tax year at a time. If you have penalties for multiple years, use FTA on the year with the largest penalty — then pursue Reasonable Cause for the remaining years.

Reasonable Cause Abatement: When Circumstances Were Beyond Your Control

If you don’t qualify for FTA (or you’ve already used it), you can request penalty abatement based on Reasonable Cause — circumstances beyond your control that prevented timely filing or payment.

The IRS evaluates Reasonable Cause requests based on whether the taxpayer exercised “ordinary business care and prudence” but was nonetheless unable to comply. Factors the IRS considers include:

• Death, serious illness, or incapacitation: Of the taxpayer, a family member, or the tax professional responsible for filing
• Natural disaster or casualty: Fire, flood, earthquake, or other disaster that destroyed records or displaced the taxpayer
• Inability to obtain records: Despite reasonable efforts, you couldn’t get necessary documents (K-1s, W-2s, etc.) in time to file
• Erroneous IRS advice: You relied on incorrect written or oral advice from the IRS
• Reliance on a tax professional: You gave a competent tax professional all necessary information, and they failed to file. Note: this is harder to prove than most taxpayers expect — the IRS holds the taxpayer responsible for selecting a competent preparer and following up.
• Financial hardship: You couldn’t pay due to circumstances beyond your control (job loss, unexpected expenses, economic downturn)

Writing an Effective Reasonable Cause Letter

The quality of your written Reasonable Cause request significantly affects the outcome. A strong request includes:

• A clear, specific explanation of what happened and when
• How the circumstances prevented you from filing or paying on time
• What steps you took to comply as soon as possible once the impediment was removed
• Supporting documentation (medical records, insurance claims, death certificates, correspondence with tax professionals, disaster declarations)

Generic statements like “I was going through a hard time” are insufficient. The IRS wants specifics: dates, diagnoses, names, and evidence. Our team at The Law Office of Pietro Canestrelli has extensive experience crafting penalty abatement requests that meet the IRS’s evidentiary standards.

Statutory Exceptions to Penalties

Beyond administrative relief, certain statutory provisions can eliminate penalties entirely:

• Reasonable Cause and Good Faith (§6664(c)): The accuracy-related penalty does not apply if you show reasonable cause and good faith for the position taken on your return
• Substantial Authority: If you had “substantial authority” for a tax position (a higher standard than reasonable basis but lower than “more likely than not”), the substantial understatement penalty doesn’t apply
• Adequate disclosure: If you adequately disclosed a position on your return (using Form 8275 or 8275-R), the negligence penalty doesn’t apply — even if the position is ultimately wrong
• Tax opinion letters: A qualified tax opinion letter can provide penalty protection for complex or aggressive positions

California Penalty Abatement

The California Franchise Tax Board has its own penalty abatement procedures, which differ from the IRS in important ways:

• California does not have a formal “First-Time Abatement” program equivalent to the IRS’s administrative waiver
• Reasonable Cause abatement is available, but the FTB tends to apply stricter standards
• The FTB assesses a late-filing penalty and a demand-to-file penalty — both can be abated separately
• FTB penalty abatement requests are submitted in writing to the address on the penalty notice

For taxpayers facing penalties from both the IRS and the FTB, a coordinated abatement strategy can maximize relief across both agencies. Our attorneys handle both simultaneously.

When to Hire a Professional for Penalty Abatement

Some penalty abatement requests are straightforward enough to handle on your own — particularly FTA requests for small amounts. But professional representation is strongly recommended when:

• Penalties exceed $5,000 (the savings justify the cost of representation)
• Multiple years are involved
• The Reasonable Cause argument is complex or requires documentary evidence
• The penalty is accuracy-related (§6662) and requires legal analysis of the tax position
• You’re also resolving the underlying tax liability (penalty abatement is often negotiated as part of a larger resolution)
• The initial request was denied and you need to escalate to a supervisor or file a formal appeal
