IRS Appeals: File Your Protest Within 30 Days To Challenge Audit Results

If you or your business disagree with an IRS audit result, the IRS appeals process can be the fastest way to resolve the dispute without going to court. The key is acting quickly and submitting a complete, fact-supported protest before your deadlines expire.

It is important to act quickly during this time. The experienced attorney at Insight Law can help you meet deadlines, challenge IRS decisions and protect your financial interests form the day you receive the 30-day letter.

The Process Often Starts With The IRS Audit And The 30-Day Letter

In many cases, the IRS dispute begins after an examination of income, estate or gift tax returns. When examination personnel propose additional tax, the IRS typically issues a 30-day letter. The commonly includes:

Letter 915(DO) (the “30-day letter”)
A copy of the examiner’s report, often called the Revenue Agent’s Report (RAR)
IRS Publication 5, which explains how to request appeals review

A “deficiency” applies only to unpaid income, estate or gift taxes. Not all tax disputes are “deficiencies.” For example, certain employment taxes and the Trust Fund Recovery Penalty do not follow the same deficiency procedures.

Our team at Insight Law can prepare and file your appeals request before the 30-day deadline to help preserve your rights.

Deadline Timeline: 30 Days Now, 90 Days Later

When you receive an IRS audit result you disagree with, your rights are tied to strict deadlines. The appeals process typically follows a two-step timeline: first, a short window to request an appeals review, and later, a final window to petition Tax Court if the dispute is not resolved. Here is how the timing usually works.

Step 1: Receive The 30-Day Letter

You usually have 30 days to respond and request an appeals conference. Missing this window can reduce your options and may accelerate the path to assessment.

Insight Law files your protest quickly and tracks every deadline so you do not lose leverage.

Step 2: If Appeals Does Not Resolve The Case, Expect The 90-Day Letter

If no settlement is reached in a non-docketed case, appeals may issue Letter 894(RO), commonly referred to as the 90-day letter (a Statutory Notice of Deficiency). You then have 90 days to file a petition with the U.S. Tax Court to continue challenging the proposed deficiency. If you do not file within that 90-day period, the IRS can assess the tax and begin collection.

Insight Law can help you respond within that 90-day window and advise whether to keep negotiating in appeals or timely petition the Tax Court to protect your position.

How To Build A Strong Written Protest

A successful protest is grounded in accurate facts and documented support. The IRS commonly sends your protest back to the examining agent for fact verification and comments before it goes to appeals. For that reason, exaggerations or factual overstatements can harm credibility and settlement opportunities.

A clear, complete protest typically includes:

Taxpayer identification information (name, address, phone)
Tax type and tax years involved
A copy or summary of the IRS proposed changes (from the RAR/Form 886-A)
Specific disagreements with each proposed adjustment, stated clearly
Your factual narrative, explaining what actually happened (not conclusions)
Your legal support, such as Code sections, regulations and relevant authorities
Supporting documents, including organized exhibits
Affidavits or declarations under penalty of perjury when helpful
A requested outcome, including the settlement position you are seeking

Your protest is generally signed under penalties of perjury, so it must be true, correct and complete to the best of your knowledge.

Insight Law can help you present the strongest facts and legal arguments without creating credibility issues that reduce settlement options. We organize your protest so the appeals officer can quickly see the facts, law and documents supporting your position.

Powerful Evidence Leads To Successful Appeals

Appeals are more likely to settle when the taxpayer can show clear factual differences between the RAR and what actually occurred. Evidence that often strengthens your case includes:

Exhibits (contracts, bank records, payroll records, invoices, accounting workpapers)
Affidavits/declarations confirming key facts
Documentation that directly contradicts the examiner’s factual assumptions

Be aware that if you submit new evidence during the appeals conference, it will often be sent back to the same examining function for review and verification, which can affect timing and strategy.

Our team at Insight Law helps you decide what to submit, when to submit it, and how to present it to maximize settlement potential.

The Appeals Conference: What To Expect

The conference requires the taxpayer’s side to present the position through documents and testimony, respond to the IRS arguments, and participate in settlement discussions. Even so, it is often strategically better for the taxpayer not to attend in person.

If the taxpayer attends, they may be asked questions on the spot. If they answer poorly, become emotional, provide evasive responses, or accidentally provide incorrect information, credibility can suffer. Taxpayers may also volunteer harmful information unintentionally. It is commonly better for the taxpayer’s facts to be presented through counsel using carefully prepared written submissions, letters or affidavits.

Another strategic benefit of the taxpayer not attending is that any settlement offer typically must be approved by the taxpayer later, which allows time to evaluate the offer and can preserve negotiating room.

Our lawyer at Insight Law can appear on your behalf and present your case in the most controlled and persuasive way possible.

Offers in Compromise

Our attorney at Insight Law can advise whether your issue belongs in appeals and which process best fits your goals.

What Does The Appeals Process Look Like For Seattle Residents?

While every case is unique, the process usually comes down to meeting strict deadlines, clearly explaining what the IRS got wrong and backing it up with organized documentation. Here are two common examples.

Example 1: Tech Employee RSU Audit

A Seattle-area taxpayer may be audited over whether RSU income was properly reported, whether basis was calculated correctly, or whether stock sales were double-counted. A strong protest often includes brokerage statements, supplemental tax reporting, and a clear reconciliation to the return.

Example 2: Restaurant Revenue Mismatch

A restaurant may face an audit based on perceived mismatches between bank deposits, reported sales and expense patterns. A successful protest often relies on clean POS reports, merchant processor records, tip reporting documentation, and explanations for non-sales deposits.

With You At Every Stage Of An IRS Appeal

The IRS appeals process can be a powerful tool to resolve tax disputes without litigation, but the process is deadline-sensitive and evidence-driven. If you have received a 30-day letter or are facing an IRS determination you disagree with, taking prompt action can protect your rights and improve your settlement position.
