6 Penalty Abatement Mistakes That Undercut Otherwise Good Requests
IRS penalty relief can look deceptively simple from the outside. A taxpayer gets a notice, writes a short explanation, mentions hardship or confusion, and hopes the penalty disappears. In practice, a lot of otherwise solid requests lose traction because the request is framed the wrong way, leaves out key facts, or asks for the wrong kind of relief.
That matters because penalties are common. The National Taxpayer Advocate reported that in fiscal year 2024, the IRS imposed 43.5 million penalties on individuals, estates, and trusts in connection with income tax filings, citing the IRS Data Book’s civil penalties table. That volume helps explain why a vague or unsupported request can get very little attention if it does not line up with the IRS’s rules and review process (Taxpayer Advocate Service).
In this post you’ll learn six common penalty abatement mistakes that can weaken an otherwise legitimate request, how the IRS generally evaluates these claims, and where a tax attorney or other qualified tax representative may add value when the facts are complicated. If you want broader background first, it may help to start with our overview of how IRS penalty relief usually works.
Scroll to the bottom for every post in this series.
1. Asking For The Wrong Type Of Relief
One of the most common mistakes is treating first-time abatement and reasonable cause as interchangeable.
They are not the same. The IRS’s current guidance explains that First Time Abate is an administrative waiver tied largely to a history of good compliance, while reasonable cause is a facts-and-circumstances analysis focused on whether the taxpayer exercised ordinary business care and prudence but still could not comply (IRS administrative penalty relief, IRS reasonable cause guidance).
That distinction often changes the entire structure of the request:
- First-time abatement tends to focus on filing history, prior penalties, and account status
- Reasonable cause tends to focus on dates, events, documentation, and causation
- Some penalties do not qualify for reasonable cause relief in the same way others do; for example, the IRS says reasonable cause generally does not apply to certain estimated tax penalties (IRS reasonable cause guidance)
A request can get weaker when a taxpayer spends two pages describing illness, staffing problems, or records disruption even though they appear to qualify for first-time relief based on clean prior compliance. The reverse also happens: someone asks for first-time relief even though they already used it or do not meet the three-year compliance rules, but they may have a credible reasonable-cause argument.
The IRS notes that if a taxpayer asks for reasonable cause but qualifies for first-time abatement, the agency may apply first-time relief instead (IRS administrative penalty relief). Even so, many requests become less persuasive when they are not clearly organized around the correct theory from the start.
What This Often Looks Like In Practice
A stronger request usually identifies, early and clearly:
- the penalty type
- the tax year or periods involved
- the relief theory being invoked
- the facts that match that theory
That is one reason many taxpayers spend time first learning the difference between waiver, reasonable cause, and broader defense strategy before sending anything formal. Our parent guide on the main paths to penalty relief goes deeper on that distinction.
2. Telling A Story Without Connecting It To The Filing Or Payment Failure
A compelling hardship story is not always enough.
The IRS states that reasonable cause is determined case by case and depends on the penalty involved and the applicable law. For failure-to-file and failure-to-pay penalties, the IRS says relief may be available where the taxpayer exercised ordinary care and prudence and was nevertheless unable to file or pay on time (IRS reasonable cause guidance, IRM 20.1.2).
That creates a common trap: the request describes a serious event but never clearly explains how that event caused the missed deadline.
For example:
- A medical issue may be significant, but the request may not explain who handled the tax matter, when the condition arose, or why no one else could access the records
- A business disruption may be real, but the request may not show why filing or payment could not be completed despite the disruption
- A family emergency may be sympathetic, but the request may not establish timing, duration, or impact on the taxpayer’s ability to comply
The gap is often causation. The IRS is not only looking for a bad event. It is often looking for a factual bridge between the event and the missed return, deposit, or payment obligation.
What Makes This Mistake So Costly
Many penalty requests fail not because the event sounds unimportant, but because the explanation never answers the question: “Why did this event prevent compliance at that specific time?”
That is why taxpayers often build better reasonable-cause requests by pairing the narrative with a timeline, records, and a direct explanation of what became impossible and when. If you want a deeper walkthrough, our related article on building a stronger reasonable-cause package with evidence would typically be the next step in the content sequence.
3. Leaving Out Evidence The IRS Actually Uses To Evaluate Reasonable Cause
The IRS’s own materials make clear that reasonable cause is not a slogan. It is a fact-specific analysis.
The Internal Revenue Manual says penalty relief determinations should be made consistently and in line with the Internal Revenue Code, Treasury Regulations, and the facts presented. IRS guidance also points reviewers to issues such as actions by the IRS, access to relevant records, and whether the taxpayer exercised ordinary business care and prudence (IRM 20.1.1, IRS reasonable cause guidance).
Yet many requests include little more than a paragraph saying:
- “I had health issues.”
- “My records were unavailable.”
- “I relied on my accountant.”
- “I was going through financial hardship.”
Those statements may be part of a valid request, but standing alone they often leave too much unstated.
Evidence That Often Helps Clarify The Request
Depending on the facts, supporting material can include:
- hospital or treatment records
- death certificates or funeral documentation
- insurance claims after fire, flood, storm, or theft
- correspondence showing records were inaccessible
- payroll or internal records showing who had filing authority
- proof of attempts to obtain records or make payment arrangements
- copies of extensions, prior notices, or account transcripts
- a dated timeline showing when the problem began and when compliance resumed
Not every case calls for the same package, and there is no universal checklist that fits all penalty types. But in general terms, a request tends to be easier to evaluate when the supporting records line up with the dates and explanation in the statement itself.
This is especially important where the taxpayer is trying to show they acted responsibly before and after the problem arose. The IRS has indicated that ordinary care, prudence, and access to records are relevant in that analysis (IRS reasonable cause guidance, IRM 20.1.1).
4. Assuming Inability To Pay Automatically Removes A Penalty
Another frequent mistake is assuming that financial hardship by itself automatically wipes out a failure-to-pay penalty.
The IRS does recognize reasonable cause for some failure-to-pay situations, but the analysis is narrower than many taxpayers expect. Its guidance says taxpayers may qualify if they exercised ordinary care and prudence and nevertheless could not pay on time (IRS reasonable cause guidance). The Internal Revenue Manual also states that failure-to-pay penalties can be abated for reasonable cause, and that abatement is not to be denied merely because the underlying tax has not yet been paid (IRM 20.1.2).
That said, “I didn’t have the money” is often not enough by itself.
The IRS may look more closely at questions like:
- What resources were available at the time?
- What expenses took priority, and why?
- Did the taxpayer try to borrow, liquidate assets, or otherwise address the liability?
- Was the nonpayment temporary or prolonged?
- What changed after the due date?
In other words, the issue is often less about whether paying was difficult and more about whether the taxpayer can show they acted with ordinary care and prudence under the circumstances.
Why This Trips Up Otherwise Legitimate Requests
A taxpayer may genuinely have been under severe financial pressure and still present the issue too broadly. If the request does not explain the full picture — business interruption, medical crisis, frozen accounts, disaster impact, or another concrete constraint — the IRS may read it as a routine inability-to-pay statement rather than a developed reasonable-cause showing.
This is also where the underlying penalty matters. Taxpayers sometimes group every penalty together, even though different penalties can involve different defenses and different relief rules. Our companion piece on which IRS penalties people often try to challenge can help readers separate those categories before drafting a request.
5. Sending A Vague Letter Instead Of A Structured Submission
A lot of penalty abatement requests are not necessarily wrong on substance. They are just hard to review.
The IRS says some requests may be handled by phone, and written requests can be made by following the notice instructions or by using Form 843, Claim for Refund and Request for Abatement (IRS administrative penalty relief, About Form 843, Instructions for Form 843). The IRS also notes that if a request for relief is denied, the denial letter may provide appeal rights, and taxpayers generally have 30 days from the rejection letter date to request an appeal through the IRS Independent Office of Appeals (IRS penalty appeal page).
Despite that, many taxpayers submit an informal letter that does not clearly identify:
- the notice number
- the tax year or quarter
- the penalty type
- the exact relief requested
- the legal or administrative basis
- the facts in chronological order
- attached exhibits
- a signature and contact information
That can create friction even where the facts are favorable. IRS personnel handle high volumes, and a scattered submission can make it harder for a reviewer to see the theory, evidence, and timeline quickly.
A More Reviewable Format Often Includes
- a short introduction identifying the taxpayer and notice
- a section stating the penalty and tax periods at issue
- a section identifying the relief sought, such as first-time abatement or reasonable cause
- a dated factual timeline
- a concise explanation tying the facts to the relevant standard
- a list of attached exhibits
- a closing request for written confirmation
For many readers, this is the point where legal or tax representation starts to matter. A tax attorney, CPA, or enrolled agent may help present the same facts in a way that better fits the IRS’s framework and preserves related tax positions. That is especially true where the penalty request overlaps with disputed liability, late-filed returns, payroll tax issues, or prior-year noncompliance. Our related article on asking for penalty relief without harming the rest of your tax position speaks directly to that risk.
6. Treating A Denial As The End Of The Road
A rejected request is frustrating, but it is not always the final word.
The IRS explains that if it denies a request to remove a penalty, the taxpayer may be able to request a conference or hearing with the IRS Independent Office of Appeals, and the denial letter typically gives the appeal rights and deadline. The IRS says this route is generally available after a written request to remove the penalty has been denied and the taxpayer receives a denial letter with appeal rights (IRS penalty appeal page).
This is where another common mistake appears: taxpayers either stop entirely after a denial, or they send back the same unsupported explanation with no new structure or evidence.
Why Denials Sometimes Happen Even In Arguably Good Cases
A denial does not always mean the facts are weak. Sometimes it reflects:
- an incomplete first submission
- the wrong relief theory
- missing documentation
- account-history issues affecting first-time abatement
- confusion about the penalty type involved
- a failure to explain causation clearly
In some cases, a denial helps reveal what the IRS found missing. That can give the taxpayer and counsel a clearer record to work with in an appeal or renewed submission, depending on the procedural posture.
This is one reason many taxpayers look for legal help once the first request has been denied. Appeals strategy often turns on more than simply repeating the story. It may involve reframing the legal basis, tightening the chronology, documenting ordinary care and prudence more precisely, or identifying whether the initial request focused on the wrong penalty defense entirely.
Why These Mistakes Matter More Than People Expect
Penalty abatement is often treated like an add-on issue — something secondary to the tax debt itself. But penalties can materially change the size of the balance, the tone of collections, and the leverage in resolving the account. A weak request can also create avoidable problems if it includes broad statements that are inconsistent with the taxpayer’s larger tax position.
That is why experienced tax counsel often look at penalty relief as part of a broader record-building exercise rather than just a one-page hardship letter. The facts, timing, and wording may all matter, particularly when the case involves multiple tax periods, business taxes, disputed assessments, or parallel issues with filing compliance.
Final Takeaway
A lot of penalty abatement requests are not denied because the taxpayer had no argument at all. They lose traction because the request asks for the wrong kind of relief, tells an incomplete story, omits evidence, overstates inability to pay, lacks structure, or stalls after the first denial.
In general terms, the strongest requests tend to match the penalty to the right relief path, explain exactly what happened and when, and support that explanation with records that show ordinary care, prudence, and a clear connection between the event and the missed obligation.
