How to Write a Penalty Abatement Letter the IRS Can Actually Approve

Most penalty abatement letters fail for the same reason. They are written as appeals to sympathy, and they are read as applications under criteria.

The IRS employee who opens your letter is not deciding whether you are a good person. They are deciding whether your facts meet the standard in the Internal Revenue Manual, and for many failure-to-file, failure-to-pay and deposit penalties, they are doing it with the help of software called the Reasonable Cause Assistant that the manual says will be used where available. Your job is to make that decision easy.

Start with the account, not the story

Before you write a word, pull your account transcript and every notice for the period. Confirm the penalties assessed, the dates, and the payments.

IRM 20.1.1.3 tells employees that relief criteria apply only after the account has been analyzed and corrected. A misapplied payment or an unposted extension should be fixed, not forgiven. If your letter is really about an IRS error, say that first, prove it, and you may not need to argue anything else. The relief categories guide explains the order the IRS follows.

The structure

A letter that tracks the IRS's own process has five parts.

• Identification. Your name, taxpayer identification number, address and phone number. The tax form, the tax period, and each penalty by name and Code section. Reference the notice number and date.
• The request. One sentence: you request abatement of the specific penalties for the specific period.
• The facts. A chronological account with dates. This is the heart of the letter.
• The analysis. Connect the facts to the standard. Cite the provision you rely on.
• The close. Restate the request, list the enclosures, and sign under penalties of perjury.

Keep it as short as the facts allow. Two or three pages is plenty for most cases. Length is not persuasion. Organization is.

Name every penalty

IRM 20.1.1.3.5 says the request must identify the penalties for which relief is requested and address the reasons applicable to each, since each penalty is for a different type of failure. It adds that if a taxpayer specifically requests relief from only one penalty, only that penalty should be considered.

So a letter that asks to remove the late filing penalty leaves the late payment penalty on the table. Name them all. Then make sure your facts explain each one. A hospitalization might explain why you could not file. Whether it explains why you could not pay is a separate question with a separate standard, discussed in failure-to-pay relief.

Write the facts the way the IRS will test them

IRM 20.1.1.3.2 lists five questions for reasonable cause. Your facts section should answer every one of them, in order:

• What happened, and when did it happen?
• During the period you were noncompliant, what prevented you from filing, paying or otherwise complying?
• How did those circumstances cause the noncompliance?
• How did you handle the rest of your affairs during that time?
• Once circumstances changed, what did you do to comply?

The manual also says the dates and explanations should clearly correspond with the events on which the penalties are based. Put the due date in the letter. Put the start and end of the event in the letter. Put the date you filed or paid in the letter. Let the reader see that they line up.

If there is a gap between when your problem ended and when you complied, explain it. Unexplained gaps are where requests die.

Cite the rule you rely on

You do not need to write a legal brief. But one or two precise citations tell the reader you know which standard applies, and they point the reader to the part of the manual that supports you.

• For reasonable cause on filing or payment: Treas. Reg. 301.6651-1(c)(1) and the relevant IRM 20.1.1.3.2.2 subsection, such as death or serious illness, or inability to obtain records.
• For erroneous written IRS advice: IRC 6404(f) and Treas. Reg. 301.6404-3.
• For the accuracy-related penalty: IRC 6664(c) and Treas. Reg. 1.6664-4.
• For information return penalties: IRC 6724(a) and Treas. Reg. 301.6724-1.

Match the citation to the penalty. Citing the wrong standard signals that the writer does not understand the request.

Attach proof

The burden of proving entitlement to relief is generally on the taxpayer; IRM 20.1.1.3.5 says so. Every important fact in the letter should have a document behind it.

The IRS website suggests the types of documentation that help: hospital or court records or a doctor's letter confirming illness or incapacity with start and end dates, documentation of natural disasters or other disturbances, copies of relevant letters and responses, and receipts or other records. Label each attachment and refer to it by label in the letter.

Redact what you do not need to share. A physician's letter confirming dates and severity is usually better than a complete medical file.

A skeleton you can adapt

Here is the shape of a strong letter, using a hypothetical taxpayer:

• Re: Form 1040, tax year 2023. Notice CP14 dated June 3, 2024. Request for abatement of the failure-to-file penalty under IRC 6651(a)(1) and the failure-to-pay penalty under IRC 6651(a)(2).
• Request: I request abatement of both penalties for 2023 based on reasonable cause.
• Facts: My return and payment were due April 15, 2024. On March 28, 2024, I was admitted to the hospital and remained there until April 26 (Exhibit A). I was the only person with access to my financial records. I was discharged with instructions to rest for two weeks (Exhibit B). I filed my return and paid the balance in full on May 14, 2024 (Exhibit C).
• Analysis: Under Treas. Reg. 301.6651-1(c)(1) and IRM 20.1.1.3.2.2.1, serious illness that prevents compliance may establish reasonable cause. My hospitalization covered the due date, and I complied within three weeks of discharge.
• Close: I request abatement of both penalties and related interest. Under penalties of perjury, I declare that the facts stated are true, correct and complete. Signature, date, phone.

Notice what the skeleton does. Every date is there. Every claim has an exhibit. The analysis is one paragraph. The reader can check it against the manual in minutes.

What to leave out

Some things weaken a letter just by being there:

• Apologies and promises in place of facts. The IRS needs to know what happened, not that you are sorry.
• Forgetfulness, mistakes and reliance on someone else to file or pay as the main reason. The manual says these generally do not establish reasonable cause. See why forgetting is not reasonable cause.
• Arguments about fairness of the tax system. Appeals says it cannot consider arguments based only on moral, religious, political, constitutional or similar objections, and a penalty letter is no place for them either.
• Anything you cannot prove. A letter is made under penalties of perjury. One false or exaggerated statement can sink an otherwise good request.

Close cleanly

End with the request restated and a signature under penalties of perjury, as Treas. Reg. 301.6651-1(c)(1) contemplates for reasonable cause statements. Include a daytime phone number. If a representative is writing for you, make sure Form 2848 is on file or attached.

Then send it to the address on the notice, or attach it to Form 843. Keep a copy of everything, including proof of mailing.

If you are denied, the letter you wrote becomes part of the record Appeals will read. Write it as if Appeals is the real audience. In many cases, it is.
