IRS Letter 854C is the written notice that the IRS has denied your request to abate or reduce a penalty. Its official title is “Penalty Waiver or Abatement Disallowed/Appeals Procedure Explained,” and it shows up most often in cases involving international information return penalties.1Internal Revenue Service. IRM 8.11.5 International Penalties The denial is not the end of the road. You can appeal it, and the office that hears the appeal is independent from the one that turned you down.
What the Letter Is Telling You
You (or your representative) asked the IRS to cancel a penalty. The IRS reviewed the request and said no. Letter 854C is that answer in writing. It does two things: it states the IRS’s reason for denying your request, and it walks through your options for challenging that decision.1Internal Revenue Service. IRM 8.11.5 International Penalties
On the letter itself, look for the specific penalty at issue, the tax period, the dollar amount, the control number, and the name of an IRS contact. Keep the original. You will refer back to it at every step.
The denial came from a compliance division. Your appeal goes to the IRS Independent Office of Appeals, which operates separately and has authority to settle or eliminate penalties when the taxpayer presents a reasonable case.2Internal Revenue Service. Appeals A “no” from compliance is not a “no” from Appeals.
Check the Deadline First
Letter 854C gives you a window to request an appeal, typically 30 days from the date printed on the letter.3Internal Revenue Service. Appeals Process That clock runs from the letter date, not from the day you opened the envelope. If you live outside the United States or the letter took time to reach you, days may already be gone.
Miss the deadline and the penalty becomes final. Interest keeps building, and the account moves toward collection. So the first task is a calendar entry, not a legal argument.
While you are looking at the letter, pull the file together. You want the original penalty notice, the abatement request you sent, whatever supporting evidence you attached, and any prior IRS responses. If your first request rested on reasonable cause, this is the moment to collect anything you did not send the first time: medical records, correspondence with a tax preparer, a disaster declaration, records showing why the filing was impossible.
How to File the Appeal
Which form the appeal takes depends on the dollar amount involved.
Small Case Request
If the total penalty, interest, and any associated tax for each period involved is $25,000 or less, a small case request is enough. That means a short written statement identifying the penalty you dispute and explaining why you disagree with the denial. There is no required format. A clear, factual letter works.3Internal Revenue Service. Appeals Process
Formal Written Protest
If any single tax period exceeds $25,000 in combined penalty, interest, and tax, you must file a formal written protest for all periods involved. The protest identifies you and the letter, states that you want to appeal to the Appeals Office, lists the periods and the items you disagree with, sets out the facts and any legal authority supporting your position, and closes with a signed declaration under penalties of perjury that the facts are true.3Internal Revenue Service. Appeals Process
Send whichever document applies to the address printed on Letter 854C, within the deadline it gives. Use certified mail with return receipt requested, or a private delivery service the IRS recognizes, so you can prove the date it arrived.
Make the Reasonable Cause Argument Stronger This Time
The IRS denied your first request, but the underlying argument may still be sound. It just needs a sharper presentation. Most international information return penalties can be abated on a showing of reasonable cause, meaning you exercised ordinary business care and prudence and still could not comply on time.
Arguments that tend to work:
- Reliance on a tax professional, when you can show you provided all the necessary information and had no reason to doubt the preparer’s work.
- Serious illness, hospitalization, or a death in the family that prevented timely filing, backed by documentation.
- Records that were destroyed, held by a third party, or otherwise inaccessible for reasons outside your control.
- A genuinely first-time filing obligation, paired with concrete facts about why the requirement was not obvious in your situation.
The argument that consistently fails is “I didn’t know I had to file,” standing alone, particularly when the taxpayer had access to professional advice. Appeals officers see it constantly. If lack of awareness is part of your story, it has to be paired with specific facts explaining why the requirement was genuinely hard to discover.
Whatever your grounds, address the specific reason the IRS gave for denying your first request. If the denial said your evidence was insufficient, supply more evidence. If it said reasonable cause does not apply to your circumstances, explain why that reading is wrong and point to authority. Restating the original request in the same words rarely changes the outcome.
Getting Representation
You can handle an Appeals matter yourself, but only attorneys, certified public accountants, and enrolled agents may represent you before Appeals.3Internal Revenue Service. Appeals Process An unenrolled preparer can attend a conference as a witness but cannot speak on your behalf.
To authorize a representative, file Form 2848, Power of Attorney and Declaration of Representative. That form lets your representative communicate with the IRS, receive your confidential tax information, and act for you throughout the appeal. You can submit Form 2848 online, which speeds up processing.4Internal Revenue Service. About Form 2848, Power of Attorney and Declaration of Representative
International information return penalties are a specialized area. A practitioner who regularly handles Form 5471, Form 5472, Form 3520, or FBAR penalty cases will know which arguments carry weight in Appeals and which do not. Given that per-form penalties in this space commonly reach $10,000 or more per year and stack across years and forms, the cost of representation is usually well below what is at stake.5Internal Revenue Service.

If Appeals Doesn’t Resolve It
Appeals is the administrative path. If the IRS later issues a statutory notice of deficiency, sometimes called a 90-day letter, you can petition the U.S. Tax Court directly. Taxpayers inside the United States have 90 days from the notice date to file the petition; those outside the country have 150 days.7Internal Revenue Service. Understanding Your CP3219N Notice Tax Court is slower and more expensive than an administrative appeal, but it offers independent judicial review when the internal process does not produce a result you can accept.
What Happens If the Penalty Sticks
If the appeal is unsuccessful and the penalty becomes final, you owe the original amount plus interest. Interest compounds daily from the date the penalty was assessed and has no cap.
If the same situation also triggered failure-to-file or failure-to-pay penalties on a related tax return, those layer on top. Failure-to-file penalties accrue at 5% of the unpaid tax per month, capped at 25%.8Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax Failure-to-pay penalties accrue at 0.5% per month, also capped at 25%. When both apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount.9Internal Revenue Service. Failure to File Penalty
If you cannot pay in full while the appeal is pending, or after it concludes, you can request an installment agreement. The IRS generally accommodates payment plans, but interest and the failure-to-pay penalty keep accruing on any unpaid balance until the account is cleared.
