10 IRS Appeal Types Fully Explained
Everything you need to know about your IRS appeal rights — deadlines, procedures, strategies, and what to expect at every level. Click any appeal type to read the complete guide.
Collection Due Process (CDP)
Your most powerful appeal right — created by IRC 6320 and 6330, CDP gives you a formal hearing before an independent Appeals Officer when the IRS files a lien or issues a final notice of intent to levy. You have 30 days to request CDP from the date on your LT11, Letter 11, or Letter 3172. CDP suspends collection, allows you to challenge the underlying tax liability, propose collection alternatives (OIC, IA, CNC), and if you disagree with the determination, petition the U.S. Tax Court within 30 days.
Learn MoreEquivalent Hearing
If you miss the 30-day CDP deadline, you have up to one year from the notice date to request an Equivalent Hearing using Form 12153. The hearing is conducted by the IRS Independent Office of Appeals and covers the same issues as CDP, but with two critical differences: collection is not suspended during the hearing, and the Appeals decision cannot be appealed to Tax Court. Still a valuable tool when the CDP deadline has passed.
Learn MoreCollection Appeals Program (CAP)
A fast, less formal alternative to CDP for challenging specific IRS collection actions including liens, levies, seizures, and proposed installment agreement rejections or terminations. CAP decisions are typically made within 5 business days. You can use CAP before or after an IRS collection action, and unlike CDP, you do not need to wait for a specific notice. The trade-off: CAP decisions cannot be appealed to Tax Court, and the program is generally not appropriate for complex legal disputes.
Learn MoreIRS Audit Appeals
When you disagree with an IRS auditor's findings, you have the right to appeal to the IRS Independent Office of Appeals. This includes examination findings from correspondence audits, office audits, and field audits. The process begins with a 30-day letter (Letter 525) proposing adjustments — you file a formal written protest. The Appeals Officer reviews the case independently and considers the hazards of litigation (the likelihood the IRS would lose in court). Most audit cases are settled at the Appeals level without going to Tax Court.
Learn MoreIRS Penalty Appeals
When the IRS denies your penalty abatement request, you have appeal rights. This covers reasonable cause denials, First-Time Abate denials, and statutory exception denials for all penalty types — failure-to-file, failure-to-pay, accuracy-related, trust fund recovery, and more. Appeals Officers independently review whether the IRS properly applied the penalty standards. You can also use Fast Track Mediation to expedite penalty dispute resolution without a formal Appeals hearing.
Learn MoreOIC Appeals
When the IRS rejects your Offer in Compromise, you have 30 days from the rejection letter date to file an appeal with the IRS Independent Office of Appeals using Form 13711, Request for Appeal of Offer in Compromise. The Appeals Officer independently reviews your financial disclosure (Form 433-A or 433-B) and the IRS's reasonable collection potential calculation. Common grounds for appeal include disputed asset valuations, improperly disallowed expenses, and calculation errors in the IRS's RCP determination.
Learn MoreIRS Lien Appeals
When a Notice of Federal Tax Lien (NFTL) is filed against your property, you have appeal rights under IRC 6320. You can challenge the lien filing through CDP (30-day deadline), Equivalent Hearing (1-year deadline), or CAP. Grounds for lien appeal include: the tax was already paid, the assessment was made in error, the lien is causing economic hardship and withdrawal would facilitate collection, the lien was filed during bankruptcy in violation of the automatic stay, or the collection statute expiration date has passed.
Learn MoreIRS Levy Appeals
When the IRS issues a levy on your wages, bank account, accounts receivable, or other property, you have appeal rights under IRC 6330. A levy appeal can challenge the proposed levy action through CDP (30-day deadline from LT11 or Letter 1058), CAP (any time), or request return of levied property. Grounds for appeal include: the levy creates an immediate economic hardship, the collection statute has expired, you have an active OIC or installment agreement, or the levy was served improperly. Attach evidence including bank statements and expense documentation.
Learn MoreU.S. Tax Court Petition
When you receive a statutory notice of deficiency (90-day letter, Letter 3219), you have 90 days (150 days if addressed outside the U.S.) to file a petition with the U.S. Tax Court to dispute the proposed deficiency without first paying the tax. The Tax Court is an independent judicial body — not part of the IRS. You can represent yourself or hire counsel. Most Tax Court cases settle before trial. If you miss the 90-day deadline, you lose the right to go to Tax Court and must pay the tax before suing for a refund in district court or the Court of Federal Claims.
Learn MoreIRS Independent Office of Appeals
The IRS Independent Office of Appeals is the administrative forum where most tax disputes are resolved without going to court. Appeals Officers are independent of the IRS examination and collection functions and are required to consider the hazards of litigation — meaning they evaluate how likely the IRS is to win if the case goes to Tax Court. The Appeals mission is to resolve tax controversies fairly and impartially. This guide covers how Appeals works, who staffs it, when you can access it, and what makes an effective Appeals presentation.
