IRS penalty abatement is the process of asking the IRS to remove or reduce a penalty because you have a clean compliance record or a good reason for the failure. It matters because penalties grow quickly and interest is charged on them. In 2026 the rules are changing: the long-standing first-time abate program is moving toward an automatic exemption for 2025 returns. This playbook explains which tool fits which penalty, how to ask, what to attach and what to do if the answer is no.
How does IRS penalty abatement work?
You start by identifying the penalty on the notice, then match it to a relief tool. The tool decides what proof you need and whether you must ask at all.
| Penalty | Standard amount (as published, 2026) | Relief tools |
|---|---|---|
| Failure to file | 5 percent of tax due per month or part of a month, up to 25 percent; minimum for returns more than 60 days late is the lesser of $525 or 100 percent of the tax for Forms 1040 and 1120 due after 12/31/2025 | FTA or AEP; reasonable cause |
| Failure to pay | 0.5 percent per month, 0.25 percent during an approved plan if you filed on time as an individual, 1 percent after the levy-notice deadline, up to 25 percent | FTA or AEP; reasonable cause |
| Failure to deposit | Governed by IRC section 6656 | FTA or AEP; reasonable cause |
| Accuracy-related | 20 percent of the underpayment attributable | Reasonable cause and good faith |
| Estimated tax | Charged separately | No reasonable cause relief |
| Foreign information returns | See foreign reporting penalties | Reasonable cause only |
When both late-filing and late-payment penalties apply in a month, the late-filing penalty is reduced by the late-payment amount. The IRS gives the example of a 5 percent failure-to-file penalty becoming 4.5 percent alongside a 0.5 percent failure-to-pay penalty.
What are first-time abate and AEP?
First-time abate applies if the same type of return was timely filed for the prior three years (or 12 consecutive quarters), and either no penalty (other than the estimated tax penalty) was assessed or penalties were later abated for reasonable cause or IRS error. Business taxpayers must also meet extra deposit-history rules. You do not need to name FTA or send supporting documents; the IRS reviews your account. You request it by calling the number on your notice or by sending a written statement or Form 843, Claim for Refund and Request for Abatement.
Automatic Exemption from Penalty begins in summer 2026. If you file or pay late on an eligible original return but filed and paid on time for the three prior years, the IRS should not assess the failure-to-file, failure-to-pay or failure-to-deposit penalty, and it sends a letter explaining that relief applied. AEP covers Forms 1040, 1065, 1120, 940, 941, 943, 944, 945 and CT-1, beginning with 2025 tax year returns and 2026 quarterly returns. The failure-to-pay penalty does not accrue on the unpaid tax. You owe any tax, interest or other penalty that AEP does not cover. If you receive a penalty notice and believe you should have qualified, contact the IRS.
| Feature | First-time abate | Automatic exemption |
|---|---|---|
| Years | 2025 returns not considered for AEP, 2026 quarterly returns, and all earlier periods | 2025 tax year returns, 2026 quarterly returns and later |
| How granted | You ask; penalty is assessed then removed | Automatic when the original return is processed |
| Failure to pay | May keep accruing until the tax is paid | Does not accrue on unpaid tax |
Neither tool covers returns filed once or infrequently because of an event, the daily delinquency penalty, or information reporting that depends on another filing.
How to request relief step by step
- Pay or arrange payment. The IRS says a good-faith payment as soon as you can may help show your initial failure to pay was not willful neglect. See payment plans.
- Identify the penalty and period. Note the notice number, tax year, penalty type and amount.
- Test first-time abate or AEP. Count the prior three years for the same return type.
- If you do not qualify, build a reasonable cause file. Describe what happened and when, how it prevented you from filing or paying, and what you did to comply.
- Ask. Call the toll-free number at the top of your notice with the notice, the penalty and your reasons ready, or send Form 843 or a signed letter to the address on the notice.
- Attach support. Use hospital or doctor's records with start and end dates, documentation of disasters, copies of correspondence and receipts.
- Follow up and appeal. If the IRS denies the request, the notice explains how to appeal; the Taxpayer Advocate Service can also help.
What counts as reasonable cause?
The IRS considers all facts and circumstances. Examples it lists include fires and natural disasters, inability to get records, death, serious illness or unavoidable absence of the taxpayer or an immediate family member, and system issues that delayed a timely electronic filing or payment. It says these generally do not qualify on their own: reliance on a tax professional, lack of knowledge, mistakes and oversights, and lack of funds, although lack of funds may qualify with other facts showing you used reasonable care.
For accuracy-related penalties, it considers the efforts you made to report the correct tax, the complexity of the issue, your education and experience, and the steps you took to seek advice. For information returns, you must show you acted responsibly before and after the failure and that there were significant mitigating factors or events beyond your control.
Interest relief
The IRS charges interest on penalties and says it will automatically reduce or remove the related interest if it reduces or removes a penalty. It does not remove interest for reasonable cause or first-time relief on the tax itself; interest can be reduced only for an unreasonable error or delay by an IRS officer or employee, requested on Form 843.

|---|---|---|
| IRS | FTA, AEP, reasonable cause, Form 843 | This page |
| CRA | Taxpayer relief provisions covering the previous 10 calendar years | CRA penalties and interest |
| India | Relief routes depend on the provision; see the India guide | India penalties and interest |
Filing deadlines abroad differ from domestic ones; the IRS points to Publication 54 for citizens and resident aliens living abroad, so confirm the correct due date before counting months.
A worked example
Meera, a Naperville professional, has filed on time every year since 2020 with no penalties. She files her 2024 return five months late in September 2025 and later receives a notice showing $600 of penalties. She calls the number on the notice, gives the notice details and asks for relief. The IRS reviews her account, finds the clean history and applies first-time abate. The related interest comes off automatically. The figures are hypothetical, and relief is never guaranteed.
Mistakes to avoid
- Writing "I did not know the rule" as your only reason.
- Sending a long story with no dates or documents.
- Ignoring the notice while waiting for relief; keep paying what you owe.
- Requesting abatement for penalties the tool does not cover, such as FBAR or Form 5471 penalties.
- Missing the appeal deadline in a denial letter.

Frequently asked questions
Can I get first-time abate more than once?
Eligibility depends on a clean three-year history, so it is not a once-in-a-lifetime waiver, but a recent assessed penalty can break the history.
Does first-time abate remove the estimated tax penalty?
No. The IRS says reasonable cause does not apply to certain penalties such as the estimated tax penalty, and FTA covers only failure-to-file, failure-to-pay and failure-to-deposit penalties.
Do I have to request AEP?
No. For eligible 2025 returns it applies automatically when the original return finishes processing, and the IRS sends a letter.
Is "I relied on my accountant" a valid reason?
Generally not by itself. The IRS expects you to know what your preparer files and to confirm that returns and payments are sent on time.
Does paying the penalty hurt my chance of relief?
Not necessarily. Form 843 is titled Claim for Refund and Request for Abatement, so it can be used for a penalty you have already paid; ask promptly because timing limits apply.
