Collection Due Process hearings: how IRC §6320 and §6330 actually work

Collection Due Process (CDP) hearings provide taxpayers with one of the most consequential procedural protections in the federal tax collection framework. Created by the IRS Restructuring and Reform Act of 1998, the CDP framework requires the IRS to provide taxpayers with notice and opportunity for a hearing before filing a Notice of Federal Tax Lien under IRC §6320 and before levying on the taxpayer's property under IRC §6330. The framework allows taxpayers to challenge the underlying liability (in certain circumstances), raise procedural and substantive defenses, propose collection alternatives, and obtain independent review by the IRS Independent Office of Appeals followed by Tax Court if the appeals determination is unfavorable.

The CDP framework is procedurally distinct from other tax dispute mechanisms. CDP hearings happen at the collection stage, not at the assessment stage. The framework doesn't allow re-litigation of liability questions that have already been resolved (through Tax Court litigation, settlement agreements, or notice of deficiency procedures that the taxpayer didn't pursue), but it does provide opportunity to raise procedural and substantive issues that haven't previously been addressed. The framework is one of the few areas where Tax Court has jurisdiction over collection matters; outside CDP, collection disputes are generally not subject to Tax Court review.

For taxpayers facing IRS collection action including federal tax liens, levies, or wage garnishment, the CDP framework provides procedural protection and substantive leverage. The hearing process delays collection during pendency, allows presentation of collection alternatives (installment agreements, offers in compromise, currently not collectible status), and provides independent review of IRS collection decisions. The procedural framework is one of the most important tools available to taxpayers in serious collection situations.

This is how the CDP framework actually works under §6320 and §6330, the procedural sequence including Form 12153 filing and Tax Court appeals, the substantive issues that can be raised, and the strategic considerations for taxpayers using CDP procedures.

When CDP rights attach

CDP rights attach to specific IRS collection actions:

Notice of Federal Tax Lien filing (§6320). The IRS must provide the taxpayer with a Notice of Federal Tax Lien Filing and Your Right to a Hearing Under IRC 6320 within 5 business days after filing the Notice of Federal Tax Lien (NFTL). The notice triggers the 30-day window for requesting a CDP hearing.

Notice of Intent to Levy (§6330). Before levying on the taxpayer's property, the IRS must provide a Final Notice of Intent to Levy and Notice of Your Right to a Hearing. The notice triggers the 30-day window for requesting a CDP hearing. Without the notice and the hearing opportunity, the IRS generally cannot levy on the taxpayer's property.

Some exceptions for special circumstances. Jeopardy levies under IRC §6331(a) and certain federal contractor levies don't require pre-levy CDP notices. Post-levy CDP rights apply in these circumstances under §6330(f).

CDP rights apply only to the specific collection action that triggered the notice. A NFTL filing for tax year 2023 gives rise to CDP rights for that lien, not for other tax periods or other collection actions. Multiple separate liens or levies typically require separate CDP requests.

The 30-day window for requesting a CDP hearing is strict. Late requests are treated as Equivalent Hearing requests (which provide some procedural protections but don't preserve Tax Court appeal rights). The strategic importance of meeting the 30-day deadline cannot be overstated.

Form 12153: Requesting a CDP hearing

CDP hearings are requested through Form 12153, Request for a Collection Due Process or Equivalent Hearing. The form covers both §6320 (lien) and §6330 (levy) hearings.

The form requires:

Taxpayer information. Name, address, taxpayer identification number, and contact information.

Tax periods and types. Specific tax periods, return types (Form 1040, Form 941, etc.), and tax amounts at issue. Multiple periods can be included in a single request if they relate to the same collection action.

Type of CDP hearing. Whether the request is for a lien hearing (§6320), levy hearing (§6330), or both. Combined hearings are common when both lien and levy actions are pending.

Issues to be raised. The taxpayer must identify the specific issues they want to raise at the hearing. Common issues include: collection alternatives (installment agreement, offer in compromise, currently not collectible), spousal defenses (innocent spouse relief), procedural challenges (notice problems, statute of limitations issues), and underlying liability challenges (only when the taxpayer didn't previously have opportunity to challenge).

Reasons for the request. Brief explanation of why the hearing is being requested. Detailed presentation typically waits until the actual hearing.

Form 12153 must be filed within 30 days of the date of the CDP notice. The 30-day window starts from the date on the notice, not from when the taxpayer received it. Mail delays don't extend the deadline; the form must be received by the IRS (or postmarked, with appropriate proof) within the 30-day window.

The filing immediately triggers procedural protections:

Collection action is generally suspended during the pendency of the CDP hearing and any subsequent appeals. The IRS won't pursue additional levies, foreclosures, or other collection actions while the CDP process is ongoing.

The collection statute of limitations under IRC §6502 is suspended during the pendency. The IRS gets back the time the case was pending in CDP, but this is balanced by the prohibition on collection during that period.

What issues can be raised at the CDP hearing

The CDP hearing allows the taxpayer to raise various issues, with some limitations:

Procedural challenges. Whether the IRS followed required procedures in pursuing the collection action. Was the Notice of Deficiency properly issued? Was the assessment timely? Was the proper notice given? Procedural defects can sometimes invalidate the underlying collection action.

Statute of limitations issues. Whether the Collection Statute Expiration Date (CSED) has expired. The 10-year collection period under §6502 starts from the assessment date and can be extended by various events. Expired CSED would prevent further collection on the relevant tax periods.

Spousal defenses. Innocent spouse relief under §6015 can be raised in the CDP hearing. The IRS will consider whether innocent spouse relief should be granted as part of the CDP determination.

Collection alternatives. The taxpayer can propose collection alternatives instead of the threatened lien or levy:

Installment agreement. Monthly payments over time. Various forms exist including guaranteed installment agreements, streamlined installment agreements, in-business trust fund express agreements, and partial payment installment agreements.
Offer in compromise. Lump sum or periodic payment that resolves the liability for less than the full amount based on doubt as to collectibility, doubt as to liability, or effective tax administration. We cover the reasonable collection potential framework that drives OIC analysis.
Currently not collectible (CNC) status. Temporary suspension of collection because the taxpayer's financial circumstances don't permit collection. Available when the taxpayer's necessary living expenses meet or exceed their income, leaving no cash flow available for tax payments.
Subordination, withdrawal, or discharge of the lien. Specific lien-related remedies that can resolve specific collection problems without resolving the underlying tax debt.

Underlying liability challenges (limited). The taxpayer can challenge the underlying tax liability only if they didn't previously have an opportunity to do so. If the taxpayer received a Notice of Deficiency and didn't petition Tax Court, didn't pay the tax and file a refund claim, or didn't otherwise have opportunity to challenge the liability, the CDP hearing may allow liability challenges. If the taxpayer had previous opportunity that they didn't pursue, the liability is generally precluded from challenge at the CDP hearing.

Equitable circumstances. Various equitable factors including economic hardship, illness, family circumstances, and similar issues that affect whether collection should proceed and what collection alternative is appropriate.

The hearing is conducted by an Appeals Officer or Settlement Officer who is independent of the original IRS collection activities. The hearing typically occurs by telephone, though in-person hearings can be requested. The procedural framework is informal compared to court proceedings; formal rules of evidence don't apply.

The hearing process

The typical CDP hearing process:

Initial review. After filing Form 12153, the case is assigned to a Settlement Officer or Appeals Officer. The officer reviews the case file and contacts the taxpayer.

Hearing scheduling. The officer schedules the hearing, typically 60-120 days after the request is filed. The taxpayer is given notice of the hearing date and the issues that will be addressed.

Pre-hearing preparation. Before the hearing, the taxpayer (or representative) should prepare:

Documentation of all issues to be raised
Financial information supporting collection alternatives (Form 433-A or Form 433-F)
Specific proposals for collection alternatives with supporting calculations
Procedural challenges with supporting evidence
Underlying liability challenges with supporting documentation (if available)

Conduct of hearing. The hearing is typically a discussion between the officer and the taxpayer (or representative) addressing the issues raised. The officer asks questions, reviews documentation, and explores possible resolutions. The taxpayer can present arguments, propose alternatives, and provide supporting information.

Officer's determination. After the hearing, the officer prepares a written determination. The determination addresses each issue raised, explains the officer's analysis, and either grants or denies the requested relief. The determination is signed and issued to the taxpayer.

Appeals to Tax Court. If the determination is adverse, the taxpayer has 30 days from the determination date to petition Tax Court for review under IRC §6330(d). The petition must specifically address the determination and provide grounds for the court's review.

Tax Court review

Tax Court review of CDP determinations is one of the most procedurally valuable features of the framework. Key features:

Jurisdiction. Tax Court has jurisdiction over CDP determinations under §6330(d)(1). The jurisdiction extends to the substantive issues addressed in the determination, including underlying liability challenges (when properly raised at the CDP hearing), collection alternative determinations, and procedural challenges.

Standard of review. The standard of review depends on the issue:

For underlying liability questions: de novo review. Tax Court evaluates the merits independently rather than reviewing for abuse of discretion. The taxpayer essentially gets a fresh look at the liability question (when liability challenges were preserved).

For other issues (collection alternatives, procedural matters): abuse of discretion review. Tax Court reviews whether the officer abused discretion in making the determination, but generally defers to reasonable determinations.

Procedural framework. Tax Court review of CDP cases follows generally the same procedures as other Tax Court matters but with some specific provisions for CDP review. Standard discovery, settlement processes, and trial procedures apply.

Settlement opportunities. Most CDP cases settle before trial. The Office of Chief Counsel (IRS attorneys) reviews cases and often negotiates resolutions during the pendency. Settlement terms can include collection alternatives more favorable than the original determination.

Trial outcomes. Cases that proceed to trial produce mixed outcomes. Underlying liability challenges (where preserved) can produce substantive relief. Collection alternative challenges are harder to win at trial because of the abuse of discretion standard.

The procedural framework provides taxpayers with substantial leverage. Even when the substantive case isn't strong, the time and resources required for the IRS to defend through Tax Court create incentive for settlement on reasonable terms. Most CDP cases that proceed beyond the initial determination resolve at some point in the appeals or pre-trial process.

CDP vs. Equivalent Hearings

When the 30-day CDP deadline is missed but the request is filed within 1 year of the CDP notice, the IRS treats the request as an Equivalent Hearing request. Equivalent Hearings provide:

Similar procedural protections. Hearing with the Appeals Office, opportunity to present issues, and written determination.

No Tax Court appeal rights. Unlike CDP determinations, Equivalent Hearing determinations are not subject to Tax Court review.

Collection action may continue. Equivalent Hearings don't automatically suspend collection action the way CDP requests do.

The procedural difference is significant. Equivalent Hearings provide procedural framework but lack the substantive protections of CDP. The strategic implication is clear: meet the 30-day CDP deadline whenever possible to preserve Tax Court appeal rights and automatic collection suspension.

How CDP fits into broader tax debt resolution

CDP is one tool in the broader tax debt resolution framework:

Early intervention. CDP hearings provide opportunity to address collection issues before liens and levies cause maximum harm. The framework encourages proactive resolution rather than reactive responses to completed collection actions.

Coordination with other resolutions. CDP hearings often serve as the procedural framework for resolving tax debt through collection alternatives. The hearing provides the opportunity to propose and obtain approval of installment agreements, offers in compromise, or currently not collectible status.

Procedural leverage. Even when no specific collection alternative is appropriate, the CDP framework provides procedural leverage. The hearing process slows collection, requires the IRS to explain and justify collection decisions, and provides independent review.

Statute of limitations protection. The suspension of CSED during CDP pendency means that taxpayers don't lose collection statute protection by pursuing CDP relief. The IRS gets back the time the case was pending, but the taxpayer is protected from collection during that time.

For taxpayers facing IRS collection action, the strategic question is typically when and how to use CDP rather than whether to use it. Most cases benefit from CDP pursuit when properly used. The procedural framework provides protections and opportunities that aren't available through other tax debt resolution mechanisms.

Strategic considerations

For taxpayers considering CDP hearings:

Meet the 30-day deadline. The single most important procedural step is filing Form 12153 within 30 days of the CDP notice. Late filings convert to Equivalent Hearings, losing the substantive protections of CDP including Tax Court appeal rights.

Be specific about issues. Form 12153 requires identifying the issues to be raised. Specific identification preserves issues; vague references may not. Identify each issue with specificity to ensure it can be addressed at the hearing.

Prepare thoroughly for the hearing. The hearing is the primary opportunity to present arguments and evidence. Thorough preparation including documentation of issues, financial information supporting collection alternatives, and legal arguments supporting positions improves outcomes substantially.

Consider professional representation. Tax professionals (Enrolled Agents, CPAs, tax attorneys) experienced with CDP hearings typically produce better outcomes than self-representation. Representation fees vary widely ($1,500-$15,000+ depending on case complexity), but the procedural framework is technical enough that professional guidance is often valuable.

Coordinate with broader resolution strategy. The CDP hearing should be used as part of a coordinated approach to the overall tax debt. Identify the appropriate resolution outcome (specific installment agreement terms, OIC parameters, CNC qualification) and use the CDP framework to obtain that outcome.

Preserve Tax Court appeal rights. The 30-day window for petitioning Tax Court after an adverse CDP determination is also strict. Plan for the possibility that appeals will be necessary and don't let the deadline pass while considering options.

Document everything. Written records of all CDP-related communications, submissions, and determinations protect the taxpayer's position. The IRS has its own records, but taxpayer-maintained documentation provides independent verification of what was raised, what was discussed, and what was determined.

Don't ignore CDP notices. Receipt of a CDP notice indicates that the IRS is about to take significant collection action. The notice creates valuable procedural rights that are lost if not exercised. Ignoring CDP notices is among the most expensive procedural mistakes taxpayers make in tax debt situations.

For taxpayers in serious tax debt situations facing imminent collection action, the CDP framework provides one of the most important procedural protections available. The framework requires the IRS to justify collection actions, allows taxpayers to propose alternatives, and provides independent review through both IRS appeals and Tax Court. The work for taxpayers is in meeting the procedural deadlines, preparing thorough presentations of the relevant issues, and engaging the resolution framework that the hearing process makes available. For cases that succeed, the framework can produce dramatically better outcomes than the alternative of allowing collection actions to proceed without challenge.
