Tax Appeals
Written in plain language for general understanding. This is educational content, not legal advice. Based on federal statutes and official sources.
What is this right?
You have the right to appeal virtually any IRS decision you disagree with. The IRS Office of Appeals is an independent division within the IRS that reviews disputed cases. Appeals officers consider your case fresh — they are not bound by the examiner's findings.
Most tax disputes are resolved at the appeals level without going to court. If you can't resolve it through appeals, you can take your case to the U.S. Tax Court, where you can challenge the IRS's assessment without paying the tax first.
When does it apply?
This right applies when:
- You disagree with the results of an IRS audit
- The IRS denies your Offer in Compromise or installment agreement
- The IRS assesses penalties you believe are unfair
- You receive a Notice of Deficiency ("90-day letter") proposing additional tax
- You disagree with a collection action (lien or levy)
Common misconceptions:
- "I have to pay the tax before I can fight it" — No. You can petition the U.S. Tax Court BEFORE paying the disputed amount. This is a critical right.
- "Appeals always side with the IRS" — Not true. Appeals officers resolve cases based on the hazards of litigation — the likelihood of the IRS winning in court. If the IRS's position is weak, appeals will often settle.
- "I need a lawyer for Tax Court" — Not necessarily. For cases under $50,000, you can use the Tax Court's simplified "small case" (S case) procedure, which is designed for self-represented taxpayers.
What should you do?
Step 1: If you receive an audit report you disagree with, file a written protest within 30 days. For assessments under $25,000, use Form 12203 (Request for Appeals Review). For larger amounts, write a formal protest letter.
Step 2: If you receive a Notice of Deficiency (90-day letter), you have exactly 90 days to file a petition with the U.S. Tax Court. This deadline is absolute and cannot be extended.
Step 3: Prepare your case. Gather all supporting documents, organize your arguments, and consider hiring a tax professional.
Step 4: At the appeals conference, be prepared to negotiate. Appeals officers have authority to settle cases — bring your best arguments and documentation.
Step 5: If appeals doesn't resolve it, file with the U.S. Tax Court. For amounts under $50,000 per year, elect the S case procedure for a faster, simpler process.
What should you NOT do?
Don't miss the 90-day Tax Court deadline. If you receive a Notice of Deficiency, this is the most important deadline in tax law. Missing it means you must pay the tax first, then sue for a refund in federal court.
Don't go to appeals unprepared. The appeals officer will take you seriously, but only if you bring documentation and coherent arguments.
Don't accept the first offer. Appeals officers expect negotiation. If their initial position is unfavorable, present your counterarguments.
Don't give up. Even if you represented yourself poorly during the audit, you can present your case fresh at appeals. New evidence is generally accepted.
How Illinois differs from federal law
Illinois has a multi-level tax appeal system:
- Informal review: Start by contacting IDOR directly to resolve disputes informally through the Informal Conference Board.
- Illinois Independent Tax Tribunal: Created in 2012 (35 ILCS 1010), this independent body hears tax disputes. You can challenge assessments without paying first (pre-payment review), unlike many states.
- Circuit Court review: After the Tax Tribunal, you can appeal to the Circuit Court and further to the Appellate Court.
- Property tax appeals: For property taxes, appeal first to the County Board of Review, then to the Illinois Property Tax Appeal Board (PTAB), then to Circuit Court.
Additional Steps in Illinois
File a petition with the Illinois Independent Tax Tribunal within 90 days of a final assessment. Visit tax.illinois.gov for forms and procedures. For property tax appeals, contact your County Board of Review.
Relevant Law: 35 ILCS 1010 (Tax Tribunal Act), 35 ILCS 200/16-160 (property tax appeals to PTAB)
