Two Powerful IRS Appeal Options—But Only One Stops Collections


When the IRS moves to seize your wages, bank account, or property, you may have the right to appeal. But should you file a Collection Appeals Program (CAP) request—or a Collection Due Process (CDP) hearing?


While both programs are designed to give taxpayers a chance to dispute IRS enforcement, the differences between them are critical—and could determine whether you can  stop a levy before it happens.


This post breaks down the key differences between CDP and CAP, when to use each, and how to protect yourself when the IRS comes knocking.


What Is a Collection Due Process (CDP) Hearing?


A CDP hearing is a formal appeal process triggered by final IRS notices, such as:


  • Letter 1058 (Notice of Intent to Levy)
  • Letter 3172 (Notice of Federal Tax Lien)


You have 30 days from the notice date to file Form 12153 and request a CDP hearing with the IRS Independent Office of Appeals.

Benefits of CDP Hearings



CDP hearings offer the strongest protection when you're facing imminent enforcement.


What Is the Collection Appeals Program (CAP)?


CAP is a faster, more informal IRS appeal process used when:


  • You disagree with a lien, levy, or seizure
  • The IRS rejected, modified, or terminated an Installment Agreement
  • You missed the CDP deadline but still want to challenge collection


You can request a CAP review by contacting the IRS and submitting a CAP Form (Form 9423).


Key Differences Between CDP and CAP


Feature CDP Hearing CAP Appeal
Stops collections? Yes Possibly (case-by-case)
Time to request 30 days from final notice Flexible, depending on IRS action
Access to Tax Court Yes No
Used for lien/levy? Yes (final notices) Yes (anytime, even pre-notice)
Used for IA changes? No Yes
Legal protections Strongest Limited

This is the more strategic option when facing IRS wage garnishment actions or other serious enforcement threats.


When to Use CDP


Use a Collection Due Process hearing if:


  • You received Letter 1058 or a Notice of Federal Tax Lien
  • You want to pause all collections while appealing
  • You want the option to take your case to Tax Court


This is the more strategic option when stakes are high.

When to Use CAP


Use the Collection Appeals Program if:


  • You missed the CDP deadline but need to appeal IRS action
  • The IRS rejected your Installment Agreement
  • You disagree with a lien or levy and want a fast resolution
  • You’re not eligible for CDP due to timing or prior use


CAP is also used to appeal IRS seizure of property.


Can You Use Both?


In some cases, yes. But typically, you must choose one. If you submit both CDP and CAP requests, the IRS will process only the valid one based on timing and eligibility.


Taxpayers in California should also be aware of California Franchise Tax Board collection actions, which can occur alongside IRS enforcement.

Frequently Asked Questions

What is the IRS Collection Appeals Program (CAP)?

CAP allows you to appeal IRS collection actions such as liens, levies, or rejected installment agreements. It provides a quick review, but once decided, you cannot take the case to Tax Court.

What is a Collection Due Process (CDP) hearing?

A CDP hearing is a formal process where you can challenge IRS collection actions. Unlike CAP, a CDP hearing preserves your right to petition Tax Court if you disagree with the outcome.

Which is faster—CAP or CDP?

CAP is generally faster because it’s designed to quickly review collection actions. CDP hearings take longer but provide stronger legal protections.

When should I request a CAP appeal?

CAP is best when you want to stop or modify an IRS action quickly and don’t anticipate needing Tax Court review. It is often used for levies, liens, or installment agreement disputes.

When should I request a CDP hearing?

CDP hearings are appropriate when you receive a Notice of Intent to Levy or a Notice of Federal Tax Lien. They preserve your Tax Court rights if you disagree with the Appeals decision.

Can I request both CAP and CDP?

No. You must choose one. Once you elect CAP, you waive the right to a CDP hearing and Tax Court review.

How long do I have to file a CDP request?

You generally have 30 days from the date of the IRS levy or lien notice to request a CDP hearing. Missing the deadline limits your options.

Which option gives me more negotiating power?

CDP hearings usually provide more leverage because of the potential for Tax Court review. However, CAP can sometimes resolve issues faster if you just need the IRS to reconsider an action.
