IRS Tax Penalty Abatement — Reduce or Eliminate Your IRS Penalties
When the IRS assesses a tax liability, the original tax is rarely the whole story. By the time most people seek help, a significant portion of what they owe — sometimes the majority — is penalties and interest that have compounded on top of the underlying tax. The failure-to-file penalty alone runs up to 25% of the unpaid tax. The failure-to-pay penalty adds another layer. Accuracy-related penalties can tack on 20% of the understated tax. These are not minor line items.
Penalty relief may be available through administrative relief, reasonable cause, a statutory exception, or correction of an IRS error. The appropriate route depends on the penalty, tax period, compliance history, and facts.
My name is Philip Falco. I am a tax attorney and a licensed CPA practicing in downtown Denver. I have been handling IRS penalty matters since 1997. If you owe IRS penalties — whether on an old audit, unfiled returns, payroll taxes, or a balance that has been growing for years — a penalty abatement analysis is one of the first things I do when I take a case. In many situations, it meaningfully changes the amount you actually have to pay.

2026 Update: Automatic Exemption from Penalty
The IRS is transitioning from First Time Abate (FTA) to Automatic Exemption from Penalty (AEP) beginning in summer 2026. AEP applies to eligible 2025 tax-year returns and 2026 quarterly returns, and subsequent periods. It is considered when an original return finishes processing.
For qualifying taxpayers, covered penalties are not assessed, and the IRS sends an explanatory notice. AEP depends on the required prior compliance history and other eligibility conditions. It does not eliminate unpaid tax, tax interest, or penalties outside the program. If you receive a penalty assessment and believe AEP should apply, contact the IRS. See IRS administrative penalty relief guidance.
When First Time Abate Still Applies
FTA remains relevant to earlier periods and eligible returns not considered for AEP. It generally requires a qualifying three-year compliance history, required filings, and payment or arrangements to pay outstanding tax. Business deposit penalties have additional conditions. A prior penalty removed for reasonable cause or IRS error does not necessarily disqualify you.
Review the return type, period, and specific penalty before requesting relief. FTA can cover qualifying failure-to-file, failure-to-pay, and failure-to-deposit penalties, including certain partnership and S corporation late-filing penalties. Accuracy-related penalties require a different analysis. A request may be made by phone or in writing as appropriate. See IRS penalty relief procedures.
Reasonable Cause Relief — When the Facts Are on Your Side
If administrative relief does not apply, reasonable cause may be available for certain penalties. The IRS considers whether you exercised ordinary business care and prudence but could not comply. The applicable standard depends on the penalty. See IRS reasonable-cause guidance.
The IRS evaluates reasonable cause requests by looking at all facts and circumstances. There is no exhaustive list of qualifying events, but circumstances that commonly support a successful reasonable cause argument include:
Serious illness or incapacitation
Your own serious illness, or the serious illness or death of an immediate family member, can constitute reasonable cause — particularly if you were the person responsible for filing or paying and the illness or death directly prevented timely compliance. The more direct the connection between the event and the filing deadline, the stronger the argument.
Natural disaster or casualty event
A fire, flood, tornado, or other casualty that destroyed your records or made compliance impossible is a recognized ground. This applies both to direct physical destruction of documents and to circumstances where the disaster consumed your full attention and resources during the compliance period.
Erroneous written advice from the IRS
If you relied on incorrect written advice from the IRS in good faith and that reliance caused the underpayment or late filing, the IRS is required by statute to abate the resulting penalty. This is a statutory exception that overlaps with reasonable cause but carries its own specific requirements — the advice must have been written, it must have been in response to your specific written request, and you must have provided accurate information in making that request.
Inability to obtain records
If your records were unavailable through no fault of your own — held by a former accountant, lost in a business dispute, or subject to a legal hold — and that unavailability prevented timely and accurate filing, this can support a reasonable cause argument. Documentation of the record availability issue is important.
Reliance on a tax professional
Hiring a preparer does not ordinarily excuse missing a filing or payment deadline. Reliance on substantive tax advice can present a different issue, particularly for accuracy-related penalties. Review the advice, the adviser’s qualifications, and the information supplied before asserting this ground. IRS reasonable-cause guidance.
Other circumstances beyond your control
The IRS’s standard is genuinely facts-and-circumstances based. Cases involving prolonged unemployment, incarceration, domestic violence, mental health crises, and other significant personal disruptions have succeeded when the connection to the compliance failure was clearly documented.
What Reasonable Cause Is Not
Ignorance of the tax law is generally not reasonable cause. Neither is forgetfulness, general financial difficulty, or the fact that you were busy. The IRS requires that you demonstrate affirmative steps to comply — that you tried, were prevented by circumstances beyond your control, and remedied the situation as soon as those circumstances allowed.
This is where professional representation matters. A poorly framed reasonable cause letter that leads with the wrong facts, omits key documentation, or makes an argument the IRS has specifically rejected in published guidance can result in a denial that is harder to overturn on appeal. I have seen taxpayers with strong underlying facts get denied because the request was written without knowledge of how the IRS evaluates these claims.
How Penalty Abatement Affects Interest
Interest on unpaid tax is not technically a penalty, and it cannot be independently abated in most cases. However, when a penalty is abated, the interest that accrued on that penalty is automatically removed along with it. This matters more than it might seem: if a penalty has been outstanding for several years, the accumulated interest on the penalty alone can be substantial.
IRS interest rates change quarterly. Use the applicable rates and periods when reviewing the account rather than applying one current rate to the entire balance.
For an individual who filed the return on time, an approved installment agreement generally reduces the failure-to-pay penalty rate from 0.5% to 0.25% per month while the agreement is in effect. Check the filing history and applicable relief before calculating the amount. IRS failure-to-pay guidance.
What Penalties Can and Cannot Be Abated
Partnership and S corporation information returns have separate late-filing penalties that can apply even when no income tax is due. See our guide to Form 1065 and 1120-S filing deadlines and penalties for calculations and potential relief.
For clarity, here is a practical summary:
Generally abatable:
- Failure to file (IRC § 6651(a)(1)) — up to 25% of unpaid tax
- Failure to pay (IRC § 6651(a)(2)) — up to 25% of unpaid tax
- Failure to deposit payroll taxes (IRC § 6656) — up to 15% of undeposited amount
- Accuracy-related penalties (IRC § 6662) — requires reasonable cause, not FTA
Generally not abatable through FTA or reasonable cause:
- Civil fraud penalty (IRC § 6663) — 75% of underpayment attributable to fraud
- Estimated tax underpayment penalties (IRC §§ 6654–6655) — separate waiver rules apply
- Frivolous return penalty (IRC § 6702)
- Trust Fund Recovery Penalty (IRC § 6672) — separate analysis required; not a penalty in the traditional sense
How I Handle Penalty Abatement Cases
When penalty abatement is part of a broader resolution — which it usually is — here is how I approach it:
Review the notice and account history. The penalty code, assessment date, filing history, and payments help identify which relief provisions may apply and whether the IRS calculation is correct.
Administrative relief check. I evaluate whether AEP was applied or whether FTA or another relief provision should be considered for the relevant return and period.
Support the appropriate request. Where reasonable cause applies, the request should connect the documented facts to the relevant standard. Follow the notice instructions; a written statement or Form 843 may be appropriate. IRS Form 843 instructions.
Coordination with overall resolution strategy. Penalty abatement rarely stands alone. In most cases it is one component of a broader resolution — alongside an installment agreement, an OIC, or a Currently Not Collectible determination. Getting the sequencing right matters: abating penalties before establishing a collection alternative, for example, can sometimes affect the RCP calculation in an OIC.
Colorado Department of Revenue Penalty Abatement
Colorado also imposes penalties on late-filed and late-paid state income taxes, and the Colorado DOR has its own penalty abatement procedures. Colorado generally recognizes reasonable cause as a basis for abatement, applying a standard similar to the federal framework — ordinary care and prudence exercised in good faith.
Colorado penalty abatement requests are submitted directly to the Colorado Department of Revenue, typically by written letter with supporting documentation. Unlike the IRS, Colorado does not have a formal equivalent to FTA — each abatement request is evaluated on its individual facts.
When I am handling both federal and Colorado tax issues, I address both penalty situations together, which avoids the common problem of resolving the federal matter and then discovering a separate Colorado penalty that was never challenged.
Frequently Asked Questions
How do First Time Abate and Automatic Exemption from Penalty differ?
FTA generally removes an assessed qualifying penalty after a request. AEP prevents assessment of covered penalties for eligible returns as they finish processing. The IRS transition to AEP begins in summer 2026; eligibility and the return period determine which relief applies.
How much can penalty abatement actually save?
Penalties can represent 25–50% or more of the total balance owed, depending on how long the debt has been outstanding and what combination of penalties was assessed. On a $50,000 tax debt that has been accumulating for several years, the penalties and associated interest on those penalties can easily exceed $15,000–20,000. Abating those penalties meaningfully changes the math on every resolution option — a lower balance makes an installment agreement more manageable and can make an Offer in Compromise viable where it otherwise would not be.
Can I request abatement if I have already paid the penalties?
Yes. A paid penalty may be refundable if relief applies and the claim is timely. The general claim period is three years from filing the return or two years from payment, whichever is later, subject to applicable exceptions and limits on the amount recoverable. Check the specific penalty and dates before filing. IRS Form 843 instructions.
Does requesting penalty abatement trigger an audit?
A penalty relief request asks the IRS to review the penalty and supporting facts. It does not provide immunity from examination of the return. Review the underlying filing and any existing examination before deciding how to respond.
What happens if the IRS denies my abatement request?
You have the right to appeal a denial to the IRS Office of Appeals. Appeals officers review abatement denials independently and frequently reach different conclusions than the initial examiner, particularly when the reasonable cause argument was not fully developed in the original request. If the IRS appeals process does not resolve the matter, judicial review in the U.S. Tax Court or federal district court may be available in some circumstances.
Can penalties be abated if my tax return was prepared incorrectly by my accountant?
Reliance on a professional is a recognized reasonable cause factor, but it is not automatic. The IRS requires that you provided complete and accurate information to the preparer, that you had no reason to question their competence, and that the error was not something you should have caught on review. The strength of this argument depends heavily on the specific facts — how the error occurred, what information you provided, and how sophisticated a taxpayer you were. I evaluate these situations individually.
Is there a deadline for requesting penalty abatement?
Review the notice immediately. Paid-penalty refund claims generally follow the three-years-from-filing or two-years-from-payment rule, subject to exceptions and refund limits. For an unpaid penalty, response and appeal deadlines still matter; do not assume you can wait indefinitely. IRS Form 843 instructions.
The Honest Picture
Not every penalty request succeeds. FTA is reliable when you meet the criteria. Reasonable cause is genuinely fact-dependent — a well-supported request from someone who experienced a significant hardship directly connected to the compliance failure has a strong chance; a vague claim that things were difficult does not. I will tell you at the outset whether the facts of your situation support a penalty abatement argument and what the realistic likelihood of success looks like.
If you have an IRS penalty notice, bring the notice, filing confirmations, payment history, and supporting records to your consultation. A review can identify the available relief and the deadlines for pursuing it.
Schedule a $500 Tax Attorney Consultation. The fee includes up to one hour of total attorney time, including review, analysis, preparation, and the telephone consultation. Additional representation requires a separate engagement.
