Dealing with the Internal Revenue Service (IRS) can feel overwhelming, especially when faced with aggressive collection actions. A Collection Appeal Request, also known as Form 9423, gives taxpayers and small business owners a structured way to challenge specific IRS collection actions without going to court. This form is part of the Collection Appeals Program (CAP), which allows for a quick review of cases such as liens, levies, seizures, or rejected installment agreements. By filing this form on time, you can stop or modify collection efforts before they create lasting financial hardship.

Form 9423 matters because it offers one of the fastest paths to relief when an IRS employee or revenue officer takes an action you believe is unfair. For example, if the IRS places a lien on your property or levies your bank account, you can request a conference with a collection manager and then file the appeal. While CAP does not provide access to Tax Court or other types of judicial review, it does allow taxpayers to resolve disputes quickly and continue working toward payment solutions like installment agreements.

This guide will explain everything you need to know about using Form 9423 effectively. You will learn the form, when it applies, and how to meet strict deadlines. We will also walk through a step-by-step filing process, highlight common mistakes to avoid, and share real-world examples. Finally, the article closes with frequently asked questions, giving you practical answers to situations many taxpayers encounter.

What is Form 9423, and how does the Collection Appeals Program (CAP) work?

Form 9423, Collection Appeal Request, is an official IRS form that taxpayers or business owners use to challenge specific collection actions taken by the Internal Revenue Service. Filing this form allows you to enter the Collection Appeals Program (CAP), which provides a fast way to resolve disputes without resorting to Tax Court. Instead of pursuing litigation, you can request that the IRS Independent Office of Appeals review the situation and decide whether the collection action was appropriate.

The IRS Collection Appeals Program is designed to be quick and accessible. Unlike a Collection Due Process hearing, which can involve longer waiting times and the possibility of judicial review, CAP decisions are generally final. They cannot be appealed further in court. However, CAP is often faster, and most cases are resolved within five to fifteen business days. This makes it a valuable option for taxpayers who need immediate relief, such as stopping a levy or preventing a seizure of assets.

It is essential to understand the scope and limitations of this appeal process. CAP can be used to challenge actions such as federal tax lien filings, levies on wages or a bank account, seizures of property, or a rejected installment agreement. It cannot be used to contest the actual amount of tax liability or the existence of a tax debt. For an official overview of your rights and deadlines, see IRS Publication 1660: Collection Appeal Rights. By using Form 9423 correctly, taxpayers gain a chance to pause or modify IRS actions and protect their financial stability while exploring longer-term solutions.

Who Can Use Form 9423 (Eligibility and When Not to Use It)

Form 9423 is available to many taxpayers facing active IRS collection actions. Individual taxpayers can use it to stop or challenge liens, levies, or seizures that affect personal property or wages. Small business owners may file for employment tax issues, rejected installment agreements, or a final seizure notice on business assets. In addition, third parties—such as someone whose property was wrongfully levied—can submit Form 9423 to protect their rights. Spouses in community property states and authorized representatives with a valid Power of Attorney (Form 2848) also have the right to file.

However, Form 9423 is not designed for every type of tax dispute. It cannot be used to challenge the existence or amount of an underlying tax liability, which must be addressed through a Collection Due Process hearing or an audit reconsideration. Similarly, taxpayers cannot use CAP to appeal issues such as trust fund recovery penalties, jeopardy levies, or disputes related to bankruptcy cases. Requests for penalty abatement or rejected offers in compromise also fall outside the CAP process and must be handled through different appeal routes.

If your case involves questions about how much you owe or whether the IRS assessed your taxes correctly, Form 9423 will not apply. A CDP hearing via Form 12153 or another administrative or judicial review form may be more appropriate in those situations. Understanding when CAP does and does not apply is essential. Filing the wrong appeal wastes valuable business days and could allow the IRS collection process to continue without interruption.

Appealable IRS Collection Actions

Federal Tax Lien Appeals

Taxpayers can use Form 9423 to challenge a federal tax lien filing or related decisions. This includes situations where the IRS files a lien against your property, denies a withdrawal request, or maintains a lien that prevents refinancing. Lien disputes may also involve ego and nominee liens, which apply when the IRS believes someone else holds property on behalf of the taxpayer. Appealing through CAP allows for a quick review of these decisions without waiting for a hearing notice from a court.

Levy and Seizure Appeals

Another everyday use for Form 9423 is to stop or dispute IRS levies or property seizures. Levies allow the IRS to take money directly from your bank account or wages, while seizures involve physical property such as vehicles, equipment, or real estate. If your levied property creates financial hardship or the IRS employee acted prematurely, you can request a review by a collection manager. This appeal can pause enforcement while the appeals conference is pending.

Installment Agreement Appeals

Taxpayers often rely on installment agreements to pay down unpaid taxes. If the IRS rejects your payment plan, terminates an existing contract, or proposes an installment agreement modification you cannot afford, Form 9423 provides a way to dispute the decision. This can be especially critical for businesses if payroll tax obligations are involved. Filing quickly ensures the IRS does not resume enforced collection during the appeal process.

Third-Party/Wrongful Levy Claims

Form 9423 may also be used when someone other than the taxpayer is affected by an IRS collection action. For example, if the IRS seizes property that belongs to a third party or withholds funds from a joint account, the actual owner can use Form 9423 to challenge the action. These cases require clear ownership documentation but can prevent serious financial harm to individuals not responsible for the underlying tax debt.

CAP vs CDP (Form 12153): Key Differences

When facing an IRS collection action, taxpayers may have two options: filing Form 9423 for a Collection Appeals Program (CAP) appeal, or filing Form 12153 to request a Collection Due Process (CDP) hearing. While both processes allow you to challenge IRS enforcement, they serve different purposes and carry different rights.

The CAP process is designed for speed. Most appeals are resolved within five to fifteen business days, and filing Form 9423 generally stops the IRS from moving forward until a decision is made. However, CAP does not allow for judicial review. Once the appeals decision is final, you cannot take the case to Tax Court. CAP may be the better choice for taxpayers seeking fast relief from actions like levies or lien filings.

In contrast, a Collection Due Process hearing provides stronger rights, including petitioning the U.S. Tax Court if you disagree with the outcome. CDP hearings also suspend the collection process and extend the statute of limitations, giving taxpayers more time. However, CDP hearings can take months to resolve. This makes CDP valuable when you want to dispute the underlying tax liability, but less practical if you need urgent relief.

Key differences between CAP and CDP:

  • Speed of Review
    • CAP (Form 9423): Usually 5–15 business days.
    • CDP (Form 12153): Several months or longer.
  • Court Access
    • CAP: No judicial review available.
    • CDP: Yes, taxpayers may petition the U.S. Tax Court.
  • Issues Covered
    • CAP: Limited to collection actions (liens, levies, seizures, installment agreements).
    • CDP: Broader scope, including the underlying tax liability.
  • Collection Suspension
    • CAP: Collection actions are paused during review.
    • CDP: Collection actions are paused during review as well.
  • Frequency of Appeals
    • CAP: You may appeal multiple collection actions.
    • CDP: Only one CDP hearing is allowed per tax period.

Choosing between CAP and CDP depends on your goals. If you want to stop a levy immediately, CAP is usually the faster solution. If you need the right to appeal to court or challenge the amount of your tax, a Collection Due Process hearing is the better fit.

Deadlines and Filing Timelines

Strict deadlines control when you can submit a Collection Appeal Request (Form 9423). Missing these deadlines may allow the IRS collection process to continue, leaving you with fewer options. Understanding how many business days you have to act is critical.

  1. Liens, Levies, and Seizures
    After completing a required manager conference, you generally have three business days to file Form 9423. The conference request must be made within two business days after receiving an IRS notice or when an IRS revenue officer takes collection action.
  2. Seizures with Special Rules
    If the IRS seizes property, you must contact the collection office within ten business days of the final seizure notice. After the manager conference, you have three business days to file the appeal.
  3. Installment Agreements
    When the IRS rejects or modifies an installment agreement, or terminates an existing plan, you have thirty calendar days to appeal. A manager conference is not required in these cases, but filing on time is essential to pause enforcement.
  4. Business Days vs. Calendar Days
    Business days exclude weekends and federal holidays. If the IRS sends you a letter on a Friday, the first business day is Monday. Counting correctly ensures that you do not lose appeal rights.
  5. Effect on Collection Suspension?
    Filing Form 9423 usually stops the IRS from moving forward with liens, levies, or seizures until an appeals decision is made. However, unlike a Collection Due Process hearing, a CAP appeal does not extend the statute of limitations on tax collection. For an inside look at how the IRS applies these deadlines, see the Internal Revenue Manual 5.1.9: Collection Appeal Rights, which outlines IRS employees' exact procedures.

Meeting these deadlines protects your right to challenge IRS enforcement. Filing even one day late can result in the IRS moving forward with actions against your property, wages, or bank account.

Pre-Filing Requirements and Checklist

Taxpayers must prepare carefully before submitting a Collection Appeal Request (Form 9423). Meeting these requirements increases the chances of success and prevents delays in the CAP process.

  1. Request a Manager Conference
    For liens, levies, or seizures, you must first ask to meet with the employee’s manager or the collection manager handling your case. This step is not required for rejected installment agreements but is mandatory in most other situations.
  2. Review the IRS Notice
    Carefully read the IRS or final notice sent by the collection office or IRS revenue officer. These documents will explain the action, your appeal rights, and the deadlines you must follow.
  3. Gather Documentation
    Collect all records that support your case. This may include proof of payments, financial statements, copies of IRS letters, or legal documents related to your tax debt. If you use a representative, ensure a current Form 2848, Power of Attorney, is attached.
  4. Identify the Tax Periods
    Confirm the specific tax period or tax account involved in the dispute. Entering the wrong year or quarter can delay your appeal and may even result in rejection by the IRS.
  5. Plan a Proposed Resolution
    Decide what you are asking for in place of the collection action. For example, you may want a reinstated installment agreement, a levy released from your bank account, or a lien withdrawn. A clear proposal shows the appeals officer you are serious about resolving your tax balance.

Following these steps before filing ensures your appeal is complete and ready for appeal review. Proper preparation also signals to the IRS Independent Office of Appeals that you understand the rules and act in good faith.

Step-by-Step Guide to Completing Form 9423

Filling out IRS Form 9423 correctly is essential for protecting your rights in the collection appeals process. Each section of the form asks for specific information; errors can delay or even block your appeal. Before you begin, download the official IRS Form 9423 PDF to ensure you work with the most current version.

  1. Provide Taxpayer Information
    Enter your full legal name, current address, and phone number. If you are a business, include your official business name and Employer Identification Number (EIN). This ensures the IRS office connects your appeal to the correct tax account.
  2. Add Representative Details (if applicable)
    If a tax professional, certified public accountant, or tax attorney will represent you, list their information and attach Form 2848, Power of Attorney. The IRS cannot discuss your case with a representative unless proper authorization is on file.
  3. List Tax Information and Periods
    Identify the type of tax involved (such as income tax, employment tax, or excise tax) and specify the exact tax period in question. This detail helps the IRS collection office know which liabilities are under dispute.
  4. Identify Collection Actions Appealed
    Check the boxes for the collection actions you are challenging. This could include a federal tax lien, a levy on your bank account, seizure of assets, or rejected installment agreements. If the IRS believes you are connected to a nominee or alter ego lien, you can also appeal that action.
  5. Write a Strong Explanation (Line 15)
    Use this space to explain why you disagree with the IRS decision. Provide facts, supporting documents, and a realistic alternative, such as reinstating an installment agreement modification or releasing a levy. A clear explanation makes it easier for the appeals review to understand your position.
  6. Attach Supporting Documents
    Include copies of IRS letters, payment records, financial statements, or legal documents that support your claim. If your appeal involves a levy, show how taking funds would create hardship or prevent payment of other unpaid taxes.
  7. Sign and Date the Form
    Sign and date the filing form to confirm its accuracy. If a representative signs on your behalf, they must note their role as an authorized party. The IRS collection will not process the unsigned forms appeals program.

Completing Form 9423 carefully reduces the chance of rejection and speeds up the appeals conference process. Once the form is complete, you can submit it to the IRS collection office that initiated the action.

How to File Form 9423

Once you have completed the Collection Appeal Request, the next step is submitting it to the proper IRS office. Filing correctly is just as important as filling out the form, since errors can delay the appeal process or allow the IRS collection action to continue.

  1. Mail Submission
    The most common way to file Form 9423 is by mail. Send it to your IRS notice's collection office or revenue officer. Always use certified mail with a return receipt requested to prove timely delivery, even if the IRS later disputes when the form was received.
  2. In-Person Delivery
    You may hand-deliver the form directly to the IRS collection office or the revenue officer handling your case. If you choose this option, request a stamped copy as proof of submission. This protects your rights if the IRS claims the form was never filed.
  3. Fax Submission
    Some IRS offices allow faxed submissions. Before using this method, confirm with the IRS collection manager that fax is accepted. Keep the fax transmission report for your records, and consider mailing a hard copy as backup.
  4. Keep Copies for Your Records
    Whether you file by mail, in person, or fax, always keep a complete copy of your collection appeal request and supporting documents. If your appeal goes to an appeals conference, these records may be needed for verification.

By filing on time and keeping proof of submission, you protect your right to appeal collection actions and ensure the IRS Independent Office of Appeals can begin its review immediately.

What Happens After Filing

The first step is submitting a Collection Appeal Request (Form 9423). Several things happen in sequence once the form reaches the IRS collection office. Understanding this timeline will help you know what to expect and how to prepare.

  1. Collection Suspension
    The IRS collection process is usually paused while your request is under review. This means levies, liens, or seizures are temporarily on hold until an appeals decision is made.
  2. Case Forwarded to Appeals
    The collection manager or revenue officer will forward your file to the IRS Independent Office of Appeals. This office operates separately from collection staff, allowing for an independent appeals review of your case.
  3. Contact from Appeals
    An appeals officer will contact you within five to fifteen business days. You may receive a hearing notice by mail or a phone call to schedule the appeals conference.
  4. Types of Appeals Conferences
    Appeals can be handled by phone, in writing, or face-to-face. Phone and correspondence are the most common. You will present your explanation, documents, and proposed resolution during this stage.
  5. Possible Outcomes
    After reviewing your case, the appeals officer may:
    • Sustain the IRS decision, leaving the collection action in place.
    • Modify the action, such as adjusting an installment agreement.
    • Reverse the decision, which could release a levy or stop a lien.

The speed and independence of the CAP appeal make it an effective way to challenge IRS collection actions. While you cannot pursue judicial review of the outcome, most taxpayers find the process helpful in gaining fast relief.

How Form 9423 Interacts with Other IRS Relief Options

Filing a Collection Appeal Request (Form 9423) is the only tool available in the broader IRS collection appeals program. Depending on the type of tax debt and the collection action being challenged, taxpayers often combine CAP with other forms of relief.

Payment Plans and Installment Agreements

Taxpayers who cannot pay their full tax balance at once may request an installment agreement. If the IRS rejects your request or modifies the plan in a way you cannot afford, Form 9423 allows you to dispute the decision quickly. Appealing through CAP can reinstate or adjust the agreement, avoiding harsher enforcement measures.

Partial Payment Installment Agreements (PPIA)

The IRS may accept a partial payment installment agreement for those unable to pay the full liability before the statute expires. If the IRS believes your proposal is insufficient and denies it, you can file a CAP appeal. While this does not guarantee approval, it gives you an independent appeals review of the IRS decision.

Offers in Compromise (OIC)

Form 9423 cannot be used to appeal a rejected OIC. These cases have a separate appeal process under the tax code. However, CAP may help pause enforcement while you consider submitting a new OIC or pursuing another relief option.

Penalty Abatement Requests

Requests to remove penalties—such as first-time abatement or reasonable cause relief—are not part of the CAP process. Instead, you must submit them separately through the IRS collection office. Still, you may use CAP to dispute a lien or levy that stems from penalties if you believe enforcement is inappropriate.

By understanding how Form 9423 interacts with these other options, taxpayers can choose the best path for their situation. Combining CAP with an installment agreement modification or other relief often provides a more complete solution to unpaid taxes.

Common Mistakes and How to Avoid Them

Many taxpayers file Form 9423 but make errors that weaken their case or cause rejection. Avoiding these mistakes increases the chance of a favorable appeals decision.

  • Skipping the Manager Conference
    Some taxpayers submit Form 9423 without first meeting with the employee’s manager or collection manager. This step is required for liens, levies, and seizures, and skipping it can result in the IRS refusing to process the appeal.
  • Filing Incomplete Forms
    Leaving blank sections, especially Line 15, makes it difficult for the IRS Independent Office of Appeals to evaluate your case. Always explain why you disagree with the IRS decision and what resolution you are requesting.
  • Sending to the Wrong Office
    A common mistake is mailing the form to the wrong IRS office. Your IRS notice will list the correct collection office or revenue officer. Filing in the wrong location can cause delays and missed deadlines.
  • Missing Documentation
    Without supporting records such as payment proofs, financial statements, or correspondence, your case may not succeed. Always attach documents that show why the IRS collection action is inappropriate.
  • Miscalculating Deadlines
    Some taxpayers confuse business days with calendar days. Filing late can cause your cap appeal to be rejected. Always confirm the exact deadline and use certified mail to establish proof of timely filing.
  • Proposing Unrealistic Solutions
    Asking for a payment plan that does not match your financial situation will weaken your case. Appeals officers seek practical solutions, such as a reasonable installment agreement or modification.

By carefully preparing your collection appeal request and avoiding these mistakes, you give yourself the best chance of stopping or modifying IRS enforcement.

Frequently Asked Questions (FAQs)

What is the difference between CAP (Form 9423) and CDP (Form 12153)?

CAP provides a fast way to appeal IRS collection actions such as liens, levies, or rejected installment agreements. It usually resolves within two weeks, but does not allow judicial review. CDP hearings, filed with Form 12153, take longer but will enable you to dispute the underlying tax liability and petition the U.S. Tax Court if you disagree with the outcome.

Does filing Form 9423 stop a levy or garnishment immediately?

Filing Form 9423 usually suspends IRS collection actions while your case is under appeals review. This pause applies to levies on wages, bank accounts, or property seizures. However, you must file within the required business days. If you miss the deadline, the IRS may continue with enforcement, and you may lose your right to appeal.

Can I challenge how much tax I owe using Form 9423?

No, the Collection Appeals Program cannot be used to dispute an underlying tax liability or the amount of your tax debt. Instead, you must request a Collection Due Process hearing or pursue other remedies, such as audit reconsideration. Form 9423 is strictly for disputing the appropriateness of an IRS collection action, such as liens, levies, seizures, or rejected installment agreements.

How long does the CAP appeal process usually take?

Most CAP hearings are resolved within five to fifteen business days, making it one of the fastest ways to stop or modify IRS collection actions. By comparison, a Collection Due Process hearing may take months. CAP is designed for speed, but once the appeals decision is issued, it is final, and you cannot seek further judicial review in Tax Court.

Do I need a tax professional to file Form 9423?

Not always. Many taxpayers file Form 9423 independently, but involving a tax attorney, certified public accountant, or enrolled agent can strengthen your case. A tax professional ensures the form is completed correctly, deadlines are met, and supporting evidence is persuasive. Professional representation is especially valuable if your case involves large tax balances or complex IRS collection actions.
