Appeal Channel Router
By Forrest Baumhover, CFP®, EA · Last verified October 13, 2026
Route a dispute to the correct IRS appeal channel — Collection Due Process, the CDP Equivalent Hearing, the Collection Appeals Program, an Offer in Compromise rejection appeal, or Audit Reconsideration — with the deadline and the IRC/IRM citation shown at every branch, not just the final answer.
How this compares to the IRS’s own tools
The IRS explains each channel in its own publications; this router asks which one fits your facts and shows the citation behind each deadline. Picking the wrong channel can silently give up rights a taxpayer never knew they had: an untimely CDP request gets an Equivalent Hearing only if the taxpayer asks for one, with no Tax Court review in most cases, and a Collection Appeals Program decision is final and binding with no judicial review at all, unlike a timely CDP determination.
This router does not re-build ground the Federal Tax Desk’s other tools already cover. For administrative penalty relief (the 2026 Automatic Exemption from Penalty program, First-Time Abate, or reasonable cause), use the Penalty Relief Router (/penalty-relief-router). For sizing a collection alternative once a channel is chosen — an installment agreement, Currently Not Collectible status, or an Offer in Compromise — use the Collection Alternative Router (/collection-alternatives). For a Trust Fund Recovery Penalty dispute under IRC §6672 — which has its own protest route via Letter 1153/Form 2751, entirely separate from the Collection Appeals Program — the Federal Tax Desk has a TFRP Exposure Calculator.
The decision this router makes
This router asks one branching question at a time, each with its own citation, and narrows to one of ten outcomes rather than a single yes-or-no answer.
The first branch sorts the dispute into one of four tracks: a lien or levy on an already-assessed liability (IRM 5.1.9.3 for Collection Due Process; IRM 5.1.9.4 for the Collection Appeals Program), a rejected Offer in Compromise (IRC §7122(e)(2)), a penalty-only dispute with no collection action (IRM 5.1.9.4.1, which excludes penalties from the Collection Appeals Program's own scope), or everything else, which routes toward Audit Reconsideration eligibility (IRM 4.13.1.2.1).
The lien/levy track asks, in order: has the IRS actually assessed the liability (IRC §6322 — a lien arises only at assessment), has a CDP notice actually gone out (IRC §6320(a) for liens, §6330(a) for levies), and is the request still within the 30-day CDP window (IRM 5.1.9.3.1). A timely answer routes to Collection Due Process, Form 12153 — the strongest channel: a timely request pauses levy and keeps Tax Court review, but also suspends the collection statute (IRC §6330(e)(1)). Missing that window but still within one year of the levy notice date or the end of the lien's five-business-day period leaves the CDP Equivalent Hearing, if the taxpayer asks for one (IRM 5.1.9.3.2.2) — no Tax Court review in most cases. Missing both windows still leaves the Collection Appeals Program open, but CAP decisions are final and binding with no judicial review at all.
The OIC track asks only whether the appeal request falls within 30 days of the rejection letter (IRS.gov) — timely files Form 13711; the IRS does not accept a late appeal, but the taxpayer can file a new offer.
Worked example: a lien or levy dispute, on an assessed liability, with a CDP notice received and the request still inside the 30-day window, routes to Collection Due Process — Form 12153, with the collection-statute-suspension and Tax Court-review citations above attached to that specific outcome.
