If you’re reading this article, you probably are facing IRS collection actions for unpaid back taxes. In that case, you may request one of two types of administrative hearings from the Internal Revenue Service:
- Collection due process hearing-also known as a CDP hearing
- A hearing under the IRS Collection Appeals Program, known as a CAP hearing
This step-by-step guide will walk you through how to use IRS Form 9423 to request a CAP hearing from the IRS Independent Office of Appeals.
What is IRS Form 9423?
IRS Form 9423-Collection Appeal Request, is the tax form that a taxpayer may use to appeal an IRS decision on collection action or proposed collection action. Once received by the IRS Office of Appeals, the IRS will suspend collection action for the duration of the appeals process.
When do you use Form 9423?
Notice of federal tax lien
If you disagree with a federal tax lien or a proposed tax lien, then you may use this form to initiate a CAP appeal. According to the Form 9423 instructions, a taxpayer must request a managerial conference with the revenue officer and his or her supervisor.
After the conference, the IRS requests that you notify the collection manager within 2 business days of the conference if you intend to continue with the CAP process. Further collection action may resume if the completed form 9423 is not received or postmarked within 3 business days of the conference.
If you request a managerial conference but no one responds, please annotate that on the form.
Levy or proposed levy
If you’ve received a levy notice, you may use this form to appeal. The process is the same as with a notice of federal tax lien. The IRS will suspend enforcement action for the duration of the appeal.
Taxpayers may file this form to appeal the seizure of property, such as wage garnishment. Also, a taxpayer may file this form if appealing a disallowed request for the return of seized property. An injured third party may also use this form.
Rejection, modification, or termination of an installment agreement request
You may appeal an IRS decision regarding a proposed installment agreement. The IRS will suspend enforcement action for the duration of this appeal.
How to complete IRS Form 9423
IRS Form 9423 is a relatively straightforward form to complete. It consists of 1 page, with 17 data fields for the taxpayer to complete.
We’ll go through this form step by step.
1. Taxpayer name
This is straightforward.
2. Taxpayer representative (if applicable)
If you have a representative, such as a certified public accountant, tax attorney, or enrolled agent, you must attach a copy of IRS Form 2848. This is the form the IRS uses to recognize a taxpayer’s power of attorney.
3. Social Security number
Insert your Social Security number
4. Taxpayer’s business phone number
5. Taxpayer’s home phone number
List your home or cellular phone number.
6. Representative’s phone number

Enter your street address.
Enter the city you live in.
Enter your state.
10. Zip code

11. Type of tax being appealed
12. Tax periods being appealed
Are you appealing collections for more than one tax year? List all the tax years that apply to your underlying tax liability.
13. Tax due
List the amount of tax due.
14. Collection action the taxpayer is appealing
This is probably where a good tax attorney will earn their money. Tax professionals who regularly deal with the CAP procedure will understand how to explain your situation to the appeals office.
Essentially, you need to:
- Explain why you disagree with the decision
- Outline how you, the taxpayer, would resolve the tax problem to the IRS’ satisfaction
- Present additional information or documentation that support your argument
Generally, the Internal Revenue Service Independent Office of Appeals will ask the Collections Division to review, verify and provide their opinion on any new information you submit. However, as the taxpayer, you will have an opportunity to respond.
16. Taxpayer signature
If someone is acting as your power of attorney, then their signature goes here.
Date you file your appeal request.
What happens if I lose my appeal?
The form instructions state that once the IRS appeals office makes a decision, it is considered binding on the taxpayer and the IRS.
There are limited circumstances in which a taxpayer may be able to present information for consideration in tax court. For example, a third party may contest a wrongful levy by filing an action in federal court. IRS Publication 4528, Making an Administrative Wrongful Levy Claim Under Internal Revenue Code (IRC) Section 6343(b) contains more details.
Before making any permanent decisions regarding IRS actions, you should consult with a tax attorney about your collection appeal rights.
