Short answer
A formal written protest asks IRS Appeals to review audit changes. Publication 5 requires it when tax and penalties for any period exceed $25,000 (IRS.gov, 2026). It must state that you want to appeal and list your name, address and phone; each disputed issue with reasons; the facts; the law; and a signed penalties of perjury statement.
Key takeaways
- You need a formal protest if any one tax period in the letter is over $25,000 in tax and penalties, or for any partnership or S corporation case.
- Publication 5 lists five required parts; the penalties of perjury declaration must be copied exactly.
- Organize the argument per adjustment: the IRS position, your facts with numbered exhibits, and the law.
- Send it to the address on your letter, not to Appeals, within the time limit in the letter (generally 30 days).
- The template is a starting point for your own facts; it does not guarantee any result.
When you need a formal written protest
A protest is how you ask the IRS Independent Office of Appeals to review an audit you disagree with. Publication 5 (Rev. 4-2021) says “you must submit a written protest to request an Appeals conference,” and that a formal protest “is required in all cases unless you qualify for a small case request” or another special appeal procedure. The usual trigger is a 30-day letter: Letter 950 after a field audit, Letter 915 after an office audit or Letter 525 after a mail audit.
| Your case | What to send | Source |
|---|---|---|
| Tax and penalties for every tax period in the letter total $25,000 (IRS.gov, 2026) or less | A small case request is enough (you may still send a formal protest) | Publication 5; Publication 3498 |
| Any one period is over $25,000 | A formal written protest, covering all periods in the letter | Publication 5 |
| Partnership, S corporation, employee plan or exempt organization case | A formal written protest at any amount | Publication 5; Publication 3498 |
The total counts the proposed change in tax, including penalties, or a claimed refund. If you qualify for the shorter route, use our small case request letter. Not sure whether to appeal at all? Read agree or appeal first. A CP2000 is not an audit report and has its own response form, so this template is not the reply to it.
What Publication 5 says a protest must contain
Publication 5 and Publication 3498 (Rev. 5-2025) list the same items. Your protest must include a statement that you want to appeal the changes the IRS proposed, plus all of the following:
- Identity. Your name, address and a daytime telephone number.
- Disputed issues. A list of all disputed issues, the tax periods or years involved, the proposed changes, and the reasons you disagree with each issue.
- Facts. The facts supporting your position on each disputed issue.
- Law. The law or authority, if any, supporting your position on each disputed issue.
- Declaration. A penalties of perjury statement, and your signature (or your representative’s) under it.
The declaration wording is set by the IRS. For a protest you sign yourself, Publication 5 gives this statement: “Under penalties of perjury, I declare to the best of my knowledge and belief, the information contained in this protest and accompanying documents is true, correct, and complete.”
A representative who submits the protest uses one of two other statements, depending on whether they have personal knowledge of the facts:
- Personal knowledge: “Under penalties of perjury, I declare that I submitted the protest and accompanying documents, and to the best of my personal knowledge and belief, the information stated in the protest and accompanying documents is true, correct, and complete.”
- No personal knowledge: “Under penalties of perjury, I declare that I submitted the protest and accompanying documents, and I have no personal knowledge concerning the information stated in the protest and accompanying documents.”
The template below uses the taxpayer version. Copy the declaration exactly; it is the one part of the letter you should not rephrase.
How to build the argument, issue by issue
Appeals reads your protest to prepare for the conference, so organize it the way the examiner organized the report. Take each adjustment on Form 4549 or 4549-A in turn and give it its own heading with three parts:
- The IRS position. One or two sentences restating the adjustment and the amount, in neutral terms. The examiner’s explanation, often on Form 886-A or attached lead sheets, tells you what the IRS concluded and why.
- The facts. What actually happened, with dates and amounts, each tied to a numbered exhibit (a log, a bank statement, a contract). Facts you cannot document should be stated as your account, not as proof.
- The law and your argument. The rule that applies and why your facts meet it. Cite the Code section, regulation or IRS publication when you know it. Publication 5 asks for authority “if any,” so a purely factual dispute can rest on facts and documents.
Three rules from IRS publications shape what to include:
- Give the examiner everything first. Publication 5 says to provide the examiner any information you want considered before you appeal. New information raised at Appeals “may first need to be considered by an IRS employee,” which will likely delay your case.
- Stay within the tax law. Appeals cannot consider arguments based only on “moral, religious, political, constitutional, conscientious, or similar objections” (Publication 5).
- Address penalties separately. If the report includes an accuracy-related penalty, treat it as its own issue. The tax code bars that penalty for any portion of an underpayment where you show reasonable cause and that you acted in good faith (IRC 6664(c)(1)).
Short and specific beats long. List agreed items as agreed so Appeals knows the scope. If records are missing, see how to rebuild and substantiate first.
How and when to send it
- Deadline. Send it within the time limit in your letter. The IRS Appeals page says that is “generally” 30 days from the date of the letter. If you need longer, ask the examiner before the date passes and get any new date in writing; see the 30-day letter page.
- Address. Mail it to the address on the letter that gave you appeal rights. The IRS says: “Don’t send your protest directly to the IRS Independent Office of Appeals.” The examination office forwards it.
- Enclosures. A copy of the letter and the examination report, any Form 2848, and the exhibits, numbered to match the protest. Send copies, never originals.
- Proof of mailing. Keep a full copy. Certified mail with a sender’s receipt postmarked by the Post Office gives you dated proof; the tax regulations treat that receipt as prima facie evidence of delivery for documents covered by IRC 7502 (Treas. Reg. 301.7502-1). Fax or upload only if your letter offers it.
- The statute. Publication 3498 says Appeals generally needs at least 365 days left on the assessment statute when it receives your case. If less remains, expect a request to sign Form 872; our Form 872 response letter covers your choices.

A filled-in example
Example (assumed facts). A sole proprietor receives Letter 950 for tax year 2023. The report proposes additional tax of $27,350 and an accuracy-related penalty of $5,470. The total for that one year is over the small case limit, so a formal protest is required. She agrees with a $1,240 meals adjustment and disputes two items.
4. Disputed issues
- Issue 1: vehicle expenses disallowed, 2023, $16,880.
IRS position: the examiner disallowed all vehicle expenses for lack of a mileage log.
Why I disagree: I kept a log during 2023 but could not locate it before the examiner’s deadline. I have since found it.
Facts: Exhibit 1 is my 2023 mileage log, recorded weekly, listing date, destination, client and miles for each trip. Exhibit 2 is my appointment calendar, and Exhibit 3 is client invoices that match the log entries.
Law or authority: IRC 274(d) allows the deduction for listed property, including passenger vehicles, when the taxpayer substantiates it “by adequate records or by sufficient evidence corroborating the taxpayer’s own statement.” The log and corroborating records show the amount, time, place and business purpose of each use. I have also sent a copy of these exhibits to the examiner. - Issue 2: accuracy-related penalty, 2023, $5,470.
Why I disagree: if any tax remains due after Appeals considers Issue 1, I had reasonable cause and acted in good faith (IRC 6664(c)(1)). I gave all my records to a paid preparer and relied on the return prepared, as shown in Exhibit 4.
Every name, amount and fact here is invented to show the structure. Your facts, records and law will differ, and Appeals may decide either issue differently.
After you send it, and when to get help
The examination office reviews your protest and forwards it to Appeals, which Publication 3498 says will contact you or your representative to arrange a conference by telephone, video or in person. If no settlement is reached, the IRS issues a notice of deficiency, and you can still petition the Tax Court within the deadline it states. A CP3219A is one version of that notice.
Many people write their own protest when the issue is factual and the records are in hand. Help is worth more when the amount is large, the dispute turns on the law, several years are involved or fraud is suggested.
- Low Income Taxpayer Clinics may represent you in Appeals for free or a small fee if you qualify (Publication 5); see LITCs on IRS.gov.
- Taxpayer Advocate Service: 877-777-4778 (IRS.gov, 2026), if an IRS problem is causing financial hardship or normal channels have failed.
- A representative: only an attorney, CPA or enrolled agent can represent you before Appeals, using Form 2848.

Frequently asked questions
It is the letter that asks the IRS Independent Office of Appeals to review proposed audit changes. Publication 5 requires one when the tax and penalties for any period are more than $25,000, and in all partnership and S corporation cases.
Use the time limit printed in your letter. The IRS says it is generally 30 days from the date of the letter. Ask the examiner for more time before that date if you need it, and get the new date in writing.
To the address on the letter that gave you appeal rights, usually the examination office. The IRS says not to send it directly to Appeals; the office that sent the letter forwards it.
Publication 5 asks for the law or authority “if any” supporting your position. A factual dispute can rest on facts and documents. Where a rule decides the issue, citing it helps Appeals see why your facts meet it.
Yes. A representative who submits the protest uses one of the two representative penalties of perjury statements in Publication 5, depending on whether they have personal knowledge of the facts. They need a Form 2848 on file to act for you.
