IRS Form 9423 – Collection Appeal Request – Dealing with IRS collection actions like liens, levies, or installment agreement disputes can be stressful. If you disagree with the IRS’s decisions, IRS Form 9423, also known as the Collection Appeal Request, provides a way to appeal under the Collection Appeals Program (CAP). This form allows taxpayers and third parties to challenge specific enforcement actions quickly and efficiently. In this article, we’ll cover everything you need to know about Form 9423, including its purpose, eligibility, how to fill it out, submission deadlines, and tips for success. As of 2026, the form remains in its February 2020 revision, ensuring straightforward access for those facing collection issues.
What Is IRS Form 9423?
IRS Form 9423 is an official document used to request an appeal of certain IRS collection actions through the Collection Appeals Program (CAP). CAP is administered by the IRS Independent Office of Appeals, which is separate from the Collection office, providing an impartial review. Unlike other appeal processes, CAP focuses on procedural fairness and offers quicker resolutions without the option for judicial review.
The form itself is a one-page document with instructions on the reverse side. You can download the PDF directly from the IRS website: https://www.irs.gov/pub/irs-pdf/f9423.pdf. Here’s a visual sample of the form for reference:
When to Use Form 9423: Eligible Collection Actions
You should use Form 9423 if you disagree with IRS actions related to collecting unpaid taxes. Eligible appeals include:
- Federal Tax Liens: Actual or proposed filing of a Notice of Federal Tax Lien (NFTL), including denials of requests for subordination, withdrawal, discharge, or non-attachment.
- Levies or Proposed Levies: On wages, bank accounts, or other property, including disallowance of requests to return levied property under IRC 6343(d).
- Seizures: Before or after property is seized but before sale.
- Installment Agreements: Rejection, modification, proposed modification, termination, or proposed termination.
- Third-Party Issues: Filing of a lien against alter-ego or nominee property, or disallowance of a property owner’s claim for return under IRC 6343(b).
CAP covers a broader range of actions than the Collection Due Process (CDP) hearing, but it doesn’t allow challenges to the underlying tax liability amount. If your case involves liability disputes, consider CDP instead.
Who Can File Form 9423?
- Taxpayers: Individuals or businesses owing taxes.
- Third Parties: Anyone whose property is affected by IRS collection actions, such as nominees or alter egos.
You can represent yourself or use a representative like an attorney, CPA, or enrolled agent. If using a representative, attach Form 2848 (Power of Attorney and Declaration of Representative).

How to Submit Form 9423 and Key Deadlines?
Submit the completed form to the IRS Collection office or revenue officer handling your case—never directly to Appeals. Deadlines vary by action:
- Liens, Levies, or Seizures: Request a manager conference within 2 business days of disagreeing. Submit Form 9423 within 3 business days after the conference (or 4 if no contact). For seizures, appeal within 10 business days of the Notice of Seizure.
- Installment Agreements: Submit within 30 calendar days of the decision notice. No mandatory manager conference, but it’s recommended.
Timely submission generally halts collection actions until resolved, unless jeopardy exists.
What Happens After You Submit Form 9423?
The IRS forwards your request to the Independent Office of Appeals for review. Appeals will contact you, review your case, and issue a binding decision (no court appeal under CAP). If false information is provided, the decision may be voided. For more complex cases, consider CDP for judicial review options.
CAP vs. CDP: Key Differences
- Scope: CAP handles more actions but no liability challenges; CDP allows liability disputes and court review.
- Timeline: CAP is faster; CDP has a 30-day request window.
- Form: CAP uses Form 9423; CDP uses Form 12153.
