IRS Penalty Abatement — Reasonable Cause & First-Time Relief
The IRS assesses approximately $40+ billion per year in civil tax penalties — and abates (removes) approximately $11–13 billion of those penalties through administrative relief. The two primary paths to penalty abatement are: reasonable cause (26 U.S.C. § 6651(a) — showing that you failed to file or pay due to circumstances beyond your control, not willful neglect) and first-time abatement (FTA) (an administrative waiver available to taxpayers with a clean compliance history for the prior 3 years). The most common penalties are: failure to file (§ 6651(a)(1) — 5% of unpaid tax per month, up to 25%), failure to pay (§ 6651(a)(2) — 0.5% per month, up to 25%), and accuracy-related penalties (§ 6662 — 20% of the underpayment for negligence, substantial understatement, or valuation misstatements). These penalties can add 25–50% to your tax bill. Understanding penalty abatement is essential for every taxpayer who's ever filed late, paid late, or made an error on a return — because the IRS removes penalties far more often than most people realize. For debts that remain after penalties, see Federal Tax Liens & Levies for enforcement tools, Offer in Compromise for settlement options, and Taxpayer Bill of Rights for your protections.

Legal Authority
- 26 U.S.C. § 6651(a) — Failure to file and failure to pay penalties (imposes penalty for each month or part thereof that a return is late or tax is unpaid; reasonable cause exception: "no penalty shall be imposed if it is shown that such failure is due to reasonable cause and not due to willful neglect")
- 26 U.S.C. § 6662 — Accuracy-related penalties (imposes 20% penalty on underpayments attributable to: negligence or disregard of rules, substantial understatement of income tax ($5,000 or 10% of tax, whichever is greater), or substantial/gross valuation misstatements)
- 26 U.S.C. § 6664(c) — Reasonable cause exception for accuracy penalties (no penalty if the taxpayer acted in good faith and there was reasonable cause for the underpayment — relied on a tax professional, followed published IRS guidance, etc.)
- 26 U.S.C. § 6656 — Failure to deposit employment taxes (penalty of 2–15% of the undeposited amount, depending on how late; reasonable cause relief available)
- 26 U.S.C. § 6404(a) — Abatements (the Secretary may abate the unpaid portion of any assessment, or any liability in respect thereof, which is excessive in amount, assessed after the expiration of the applicable period of limitations, or erroneously or illegally assessed)
- 26 U.S.C. § 6404(e) — Abatement of interest attributable to error or delay (the Secretary may abate interest on an underpayment if the interest is attributable to unreasonable error or delay by an IRS officer or employee; also abates interest for taxpayers with net worth below $7 million in some cases)
- 26 U.S.C. § 6404(g) — Suspension of interest — failure to notify taxpayer (if the IRS does not mail a notice of deficiency within 18 months of the filing date, interest on any resulting deficiency is suspended for the period of non-notification)
How It Works
The IRS will abate a penalty under reasonable cause when you can demonstrate that your failure to file, pay, or report accurately resulted from circumstances that prevented compliance despite exercising ordinary business care and prudence — serious illness, death of a family member, natural disaster destroying records, reliance on incorrect professional advice, inability to obtain necessary records, or IRS errors or delays. The burden is on you to show you tried to comply and that circumstances beyond your control prevented it. The most accessible relief is first-time abatement (FTA), an administrative policy under IRS Internal Revenue Manual § 20.1.1.3.6.1 (not a statutory right but widely available): any taxpayer who has filed all required returns or valid extensions, has no assessed penalties in the 3 prior tax years, and has paid or arranged payment of any tax due can request FTA for failure-to-file, failure-to-pay, or failure-to-deposit penalties — but not accuracy-related penalties — simply by calling the IRS at the number on the penalty notice, often receiving relief on the spot.
The accuracy-related penalty under § 6662 imposes a 20% add-on to any underpayment attributable to negligence (failure to make a reasonable attempt to comply), substantial understatement (understatement exceeds the greater of $5,000 or 10% of tax), or valuation misstatements; you can avoid it by showing reasonable cause and good faith — reliance on a qualified tax professional, disclosure of an uncertain position on Form 8275, or having substantial authority for the position taken. To request reasonable cause abatement, write a letter or file Form 843 with supporting documentation (medical records, disaster declarations, professional correspondence), and submit it at the time of payment, during an audit, through IRS Appeals, or in Tax Court; if the underlying balance remains unmanageable after abatement, an installment agreement or offer in compromise may address the remaining tax.
How It Affects You
If you filed or paid late and have a clean prior compliance history: Call the IRS at the number on your penalty notice and ask for first-time abatement (FTA). The IRS agent will check whether you've been penalty-free for the prior 3 tax years and, if so, can typically remove the failure-to-file or failure-to-pay penalty on the spot. This is an administrative policy (IRM 20.1.1.3.6.1), not a right — but it's widely granted and requires no documentation, no letter, no Form 843. FTA is available only once every 3 years and only for the first penalty year. If you owe a $500 failure-to-file penalty and haven't had a penalty in 3 years, you could resolve this in a 10-minute phone call. Note: FTA does not cover accuracy-related penalties (§ 6662) — those require reasonable cause.
If you filed or paid late due to circumstances beyond your control: Document your reasonable cause with specifics and file Form 843 or write a letter to the IRS. Common successful reasons: serious illness or hospitalization of you or an immediate family member (attach medical records), death in the immediate family, fire or natural disaster that destroyed your records, or incorrect written advice from a tax professional (attach the advice). The key is showing you exercised ordinary business care and prudence but still couldn't comply. Generic hardship explanations ("I was going through a difficult time") rarely succeed. Specific documented circumstances do. Important: request abatement only after the penalty has been assessed — most IRS penalty notices start the clock for abatement requests.
If you're a small business owner with a failure-to-deposit penalty: Employment tax deposit penalties (§ 6656) range from 2% (1-5 days late) to 15% (10+ days or amounts still unpaid after first IRS notice) — the steepest penalty schedule in the tax code. Reasonable cause relief is available, but the bar is higher than for filing/payment penalties because the IRS considers timely payroll deposits a strict employer obligation. Document any specific external cause: bank processing failure, payroll system outage, natural disaster, or severe illness that made timely deposit impossible. If the failure was caused by a payroll service provider's error, the IRS generally views that as your responsibility — though you may have a separate claim against the payroll service. FTA covers the failure-to-deposit penalty too, so always check your 3-year compliance history first.
If you received an accuracy-related penalty (§ 6662) after an audit: The IRS assessed a 20% penalty on top of the tax owed — but you can avoid it by demonstrating reasonable cause and good faith. The strongest defense: you relied on advice from a qualified tax professional who knew all the relevant facts. Attach the written advice (or email) showing what you told them and what they recommended. Second defense: the position had substantial authority — meaning at least 40% support in case law, IRS guidance, or legislative history (the § 6662 standard). Disclsosing an uncertain position on Form 8275 can also protect you from the accuracy penalty even if the IRS disagrees with your position. If you're in Tax Court, penalties are litigated separately from the underlying tax — raise the reasonable cause defense explicitly.
State Variations
IRS penalty abatement applies to federal penalties only:
- Most states impose their own filing, payment, and accuracy penalties for state tax
- State penalty abatement rules vary — some states follow the federal reasonable cause standard; others have different criteria
- Some states have their own first-time abatement-like policies; others do not
- State penalty abatement must be requested separately from federal
Implementing Regulations
- 26 CFR 301.6651-1 — IRS failure to file/failure to pay penalties (calculation, reasonable cause standards, and the first-time penalty abatement administrative waiver)
- 26 CFR 301.6662-1 through 301.6664-4 — IRS accuracy-related penalties and fraud penalties (substantial understatement, negligence, reasonable cause and good faith exceptions)
- IRS Internal Revenue Manual Part 20 — Penalty and interest handbook (penalty abatement criteria, reasonable cause determinations, and first-time abatement (FTA) procedures)
Pending Legislation
No standalone penalty abatement reform bills have been introduced in the 119th Congress. Penalty provisions appear in broader IRS reform legislation — see IRS Enforcement and Taxpayer Bill of Rights.
Recent Developments
The IRS provided automatic penalty relief for 2020 and 2021 tax year failure-to-file penalties due to COVID-19 processing backlogs — abating approximately $1 billion in penalties. First-time abatement has become increasingly well-known among taxpayers and practitioners, though the IRS does not actively publicize it. The National Taxpayer Advocate has recommended codifying FTA as a statutory right (rather than an administrative policy), expanding reasonable cause standards, and improving the penalty notice process to clearly inform taxpayers of their abatement options.
- IRS penalty abatement processing under DOGE (2025): DOGE workforce reductions at the IRS have affected penalty abatement processing times. Written penalty abatement requests (Form 843) require manual review; IRS processing times for abatement requests increased from 4-6 weeks pre-DOGE to 8-16 weeks in 2025. Taxpayers who are current on all other tax obligations and timely filed prior years face a strong FTA claim — but getting the IRS to process the request requires patience or professional representation. The IRS Taxpayer Advocate can intervene for economic hardship cases.
- Underpayment penalties and safe harbors (2025): The §6654 estimated tax underpayment penalty — which applies when taxpayers don't pay sufficient estimated taxes during the year — is calculated based on the prior-year underpayment rate. With underpayment rates at approximately 7-7.5% in 2025-2026, the annualized underpayment penalty is meaningful. Safe harbors: pay 100% of prior-year tax (110% if prior-year AGI exceeded $150,000), or 90% of current-year tax. Taxpayers with variable income (self-employed, investors) face the most underpayment risk; quarterly estimated tax planning is critical.
- Reasonable cause standards for AI-generated errors: Tax practitioners and IRS examiners have encountered a new penalty abatement question: when a taxpayer relied on AI-generated tax advice (from a tax preparation software AI assistant or a ChatGPT prompt) that was incorrect, does that constitute "reasonable cause" for penalty abatement? The IRS has not issued specific guidance. The reasonable cause standard requires showing the taxpayer acted in good faith and with ordinary business care — relying on a licensed tax professional satisfies this; relying on a free AI tool may not, depending on the taxpayer's sophistication and the circumstances.
- 2022/2023 penalty relief continues to matter: The IRS's Notice 2022-36 (automatic penalty relief for 2020 and 2021 returns filed late due to COVID disruptions) and Notice 2023-56 (automatic relief for 2022 returns filed late in certain circumstances) provided approximately $3 billion in aggregate penalty relief. Taxpayers who still received or were assessed penalties for those years despite qualifying for relief should file Form 843 for abatement — the IRS has not always automatically applied the relief to all qualifying taxpayers. Practitioners continue to find penalty relief opportunities for clients who didn't know about these notices.
