How To Write A Penalty Abatement Letter: We Can Help
Not sure which type of relief applies to you? Take the 10-second check below.
The Two Ways A Penalty Gets Removed
The IRS removes penalties through one of two doors. The first is first-time penalty abatement, an administrative waiver available if you had no penalties in the prior three tax years, have filed all required returns, and have paid or arranged to pay any tax you owe. The second is reasonable cause relief, which applies when circumstances genuinely beyond your control caused the late filing or payment, regardless of your penalty history.
First-time abatement is the faster path when you qualify, since it does not require you to prove anything beyond your clean three-year record. Reasonable cause takes more documentation but can apply even if you have been penalized before.

What Counts As Reasonable Cause
The IRS accepts a fairly specific list: a death in the immediate family, a serious illness or medical emergency, an IRS error, destruction of records in a fire or natural disaster, or being unable to obtain records despite reasonable effort. What it does not accept is a simple lack of funds or "I forgot," on their own, without something else behind them.
| Usually accepted | Usually rejected |
|---|---|
| Death or serious illness in the family | Forgetting the deadline |
| Natural disaster that destroyed records | Simple lack of funds, alone |
| Documented IRS error | Being too busy with work |
| Incorrect advice from a competent tax professional | Not knowing the filing requirement existed |
How To Structure The Letter Itself
Keep it to one or two pages. Open by identifying yourself, the tax year, and the exact penalty you are requesting relief from. Walk through what happened in chronological order, tie each fact directly to one of the accepted reasonable cause categories, and close with a direct request, for example: "Please accept my petition for abatement of penalties with reasonable cause under IRM 20.1.1.3.2."
Attach copies, never originals, of anything that documents your claim: hospital records, a death certificate, insurance correspondence, or a letter from a tax professional. If you are requesting first-time abatement instead, you can often do it by phone or through the IRS's online tools rather than a written letter, since it does not require proving reasonable cause.
What Happens After You Send It
The IRS may remove the penalty immediately, or it may agree to remove it only once the underlying tax is paid in full. If the request is denied, you generally have the right to appeal, and in some cases penalty relief connects to a broader resolution such as a payment plan for the remaining balance. Interest tied directly to an abated penalty is typically reduced along with it, though interest on the underlying tax itself continues to accrue until that balance is paid.
Frequently Asked Questions
What is an IRS penalty abatement letter?
It is a written request asking the IRS to remove penalties, such as failure-to-file or failure-to-pay penalties, based on reasonable cause. The letter identifies the tax year and penalty, explains the circumstances, and includes supporting documentation.
What qualifies as reasonable cause for IRS penalty abatement?
Common accepted reasons include a death in the immediate family, a serious illness or medical emergency, destruction of records by fire or natural disaster, a documented IRS error, or incorrect advice from a competent tax professional. A simple lack of funds generally does not qualify on its own.
What is first-time penalty abatement?
It is an administrative waiver available if you had no penalties in the prior three tax years, have filed all required returns, and have paid or arranged to pay any tax owed. It does not require proving reasonable cause and can often be requested by phone.
How do I request IRS penalty abatement?
You can request first-time abatement by phone or in writing. For reasonable cause relief, you typically submit Form 843 or a written letter explaining the circumstances with supporting documents, sent by certified mail to keep a record of the date.
How much can be abated?
The IRS generally removes penalties tied to the tax year or years in the request, most often the first year, and there is an informal ceiling on the size of penalty typically abated administratively, though the agency has not published an exact figure.
How long does penalty abatement take?
Phone requests for first-time abatement can be resolved the same call in some cases. Written reasonable cause requests commonly take several weeks to a few months, depending on IRS workload and whether additional documentation is requested.
Does penalty abatement remove interest too?
Interest that was charged specifically on the abated penalty is typically reduced along with it. Interest on the underlying tax balance itself continues to accrue separately until that balance is paid in full.
Can I request abatement if I already paid the penalty?
Yes. You can request a refund of a penalty already paid using Form 843, Claim for Refund and Request for Abatement, as long as you are within the statute of limitations for claiming a refund.
What if my penalty abatement request is denied?
You generally have appeal rights. You can request reconsideration or escalate through the IRS Office of Appeals, and in some cases a broader resolution such as an installment agreement can be arranged for the remaining balance.
Do I need a tax professional to write the letter?
No, you can write it yourself, but a tax professional can help make sure the facts are tied clearly to an accepted reasonable cause category and that the documentation is complete before you submit it.
