That is exactly what IRS Form 9423 does under the Collection Appeals Program, often within days, not months. CAP decisions are binding, they are typically quicker than CDP, and once you submit correctly, collection is usually paused unless the IRS believes collection is at risk.
If you only remember one thing, file Form 9423 with the IRS Collection contact on the notice, not directly with Appeals. That single routing choice can save you days.
Key Takeaways
- Use Form 9423 to appeal a lien, levy, seizure, or an installment agreement decision under the Collection Appeals Program, then expect a faster, focused review.
- After a required manager conference for most actions, tell Collection within 2 business days that you will submit Form 9423, and get it received or postmarked within 3 business days. This timing preserves the pause on enforcement.
- For seizures, you have 10 business days from the Notice of Seizure to appeal through CAP.
- For rejected, modified, proposed for modification, proposed for termination, or terminated installment agreements, you generally have 30 days to appeal, and levy action is restricted by statute during that window and while a timely appeal is pending.
- CAP is final and not court reviewable. If you need the option to go to Tax Court or to contest the underlying tax, consider CDP via Form 12153 instead.

What Is Form 9423 and How CAP Works
Form 9423 is your request for a Collection Appeals Program review. You use it when the IRS has taken or plans to take a collection action you believe is wrong, premature, or disproportionate. CAP looks at whether the IRS followed procedure and whether the action fits the facts, and it moves quickly. In most cases, once you submit a timely CAP request to the Collection office that issued the action, collection is paused until Appeals decides, unless collection is in jeopardy. Decisions are binding on both sides, and there is no judicial review of a CAP determination.
When to Use Form 9423
File Form 9423 when you face or anticipate any of the following, and you want fast scrutiny and a potential hold on enforcement:
- Federal tax lien, filed or proposed
- Levy or proposed levy, including bank or wage levy
- Seizure already made
- Installment agreement, rejected, modified, proposed for modification, proposed for termination, or terminated
- Denial of a request to return levied property These are all squarely within CAP’s scope.
The One Thing That Trips Up Firms
Routing. Do not send Form 9423 to Appeals. Mail, fax, or deliver it to the address or contact on the triggering notice, typically the revenue officer or local Collection office. Submitting to Appeals first can delay or derail routing, and timing is everything in CAP.
CAP vs. CDP, Choosing the Right Path
Both CAP and CDP can halt enforcement once you file properly, yet they serve different goals. Use CAP when speed and procedural review are paramount. Use CDP when you need broader rights, including Tax Court review and, when allowed, a chance to dispute the underlying liability.
CAP vs. CDP At A Glance
| Item | CAP, Form 9423 | CDP, Form 12153 |
| What it reviews | Collection action propriety and procedure | Collection action, and in some cases underlying liability |
| Typical speed | Days to weeks | Weeks to months |
| Court review | Not available | Available if you file timely |
| Manager conference | Required for most non‑IA issues | Not required |
| Installment agreement timing | 30 days to appeal, levy restricted by statute during that window and pending appeal | CDP clock runs off specific lien or levy notices, generally 30 days |
| Where to file | Collection office on your notice | Address on your CDP notice |
| Primary use case | Fast relief from a levy, lien, or seizure, or IA decisions | Preserve court rights, consider underlying tax |
| Citations, CAP file to Collection and is fast, no court review. CDP, timely 30 days, court review preserved if timely. |
Deadlines You Must Calendar
- Manager conference window, notify intent within 2 business days, then file within 3 business days after that conference for most non‑IA issues.
- Seizure, 10 business days from the Notice of Seizure to request CAP.
- Installment agreements, 30 days to appeal rejections, modifications, proposed terminations, and terminations, with levy restrictions during that period and while a timely appeal is pending.
Steps To Take Before You File Form 9423
Preparation is half the win. Two moves set up a clean, fast review, the manager conference, then a complete evidence packet.
Request a Manager Conference
Call the revenue officer or the number on the notice, then ask to speak with the Collection manager. State exactly what you disagree with and what you want, for example levy release, lien withdrawal, or IA reinstatement. If you cannot resolve it, tell the manager you intend to file Form 9423. Note the date, time, and the manager’s name. Then, meet the CAP timing, tell Collection within 2 business days that you plan to file, and get the form received or postmarked within 3 business days after the conference. If the manager does not respond within 2 business days, you may submit Form 9423 and note that on the form, in which case the postmark target is within 4 business days of your conference request.
Gather Supporting Documents
Build a labeled evidence packet so Appeals can verify facts quickly:
- IRS notices that triggered the action, include notice numbers, dates, and the office or officer name
- Identity and tax period details, SSN or EIN, return copies for the period in dispute, and a signed Form 2848 if represented
- Financials, recent pay stubs, three months of bank statements, P&L or ledger, monthly expense summary, and if relevant a current Form 433
- Action‑specific documents, prior payments, canceled checks, IA terms and payment history, property valuations, seizure receipts
- A one‑page chronology with the relief you want, for example, release, withdrawal, modification These materials allow Appeals to review substance, not guesswork.
How To Complete Form 9423
Taxpayer Information, Keep It Exact
Match IRS records to prevent delays. Use the legal name on file, the correct SSN or EIN, the full mailing address, and a reachable phone number. If a representative will act for you, attach Form 2848 with precise taxpayer, tax types, periods, and the Collection office or case ID. Sign under penalty of perjury, or have your authorized representative sign within the scope of their 2848.
Identify The Collection Action You Are Appealing
Specify the action, lien filed or proposed, levy or proposed levy, seizure, or an IA decision. Include the notice or letter number, the date on the notice, the IRS office or revenue officer’s name, tax type and period, and the total assessed amount. Note whether the action is proposed or already executed. If there are multiple actions, list each with its identifiers. Precision speeds intake and routing.
Write A Tight, Evidence‑Driven Explanation
Use numbered facts with dates, figures, and cross‑references to exhibits:
- Open with the action and outcome you seek, for example, “Appeal of Notice of Intent to Levy dated 08/12/2025, requesting levy release.”
- Tie each assertion to a labeled exhibit, for example, “1) Three months of bank statements show net monthly loss, Exhibit A. 2) Approved direct‑debit IA on 05/15/2025, confirmation ID ####, Exhibit B.”
- If claiming hardship, summarize net income, allowable expenses, and disposable income, with references to your ledger or Form 433 and exhibits.
- Close with a concrete proposal, for example IA terms, lien withdrawal after payment, levy release, or a short enforcement hold to complete documentation. This structure mirrors how Appeals reads the file, and it cuts the back‑and‑forth.
Where and How To Submit Form 9423
Send Form 9423 to the IRS Collection contact on the notice, the local Collection office, or the assigned revenue officer, not to Appeals. Use certified mail with return receipt or a fax with a transmission confirmation, and keep a full copy of everything you send. If you met with a manager, preserve the 3‑business‑day filing window after that conference, and notify the officer or manager within 2 business days that you will submit.
Proof Of Submission, Do Not Skip This
Your best defense is a clear paper trail. Keep the certified mail receipt or fax confirmation with your copy of Form 9423, Form 2848, and all exhibits. If you filed after a manager conference, your proof shows you hit the 2‑day intent notice and the 3‑business‑day postmark. For a seizure, track the 10‑business‑day appeal window from the Notice of Seizure date.
What Happens After You File
Once the Collection office receives your CAP request, it forwards the case to the IRS Independent Office of Appeals. Appeals acknowledges the case, may ask Collection to review any new information, then schedules an informal conference by phone, video, mail, or in person. Many matters resolve within days to a few weeks. During a timely CAP, collection normally stops unless the IRS believes collection is at risk. The decision is binding on you and the IRS.
Practical Tips For The Appeals Conference
- Have your packet open to the same exhibit list you sent, so you can cite tab and page.
- Lead with the remedy you want, then the facts, then the exhibits, in that order.
- Be ready to answer questions about ability to pay, alternative remedies, and timelines.
- If you need a short hold to complete a payment or to upload missing proof, ask for it directly, with a specific date.
CAP vs. CDP, How To Decide In Real Life
Choose CAP when you need speed to pause a levy or to address a lien filing that just hit a financing deal. Choose CDP when you need the right to petition Tax Court if you disagree with Appeals, or when you need to raise the underlying liability in a qualifying case. File CDP on Form 12153, generally within 30 days of the qualifying notice. Send it to the address on that notice, not to Appeals. A timely CDP request preserves the right to Tax Court review if you still disagree after Appeals.
Installment Agreements, Special Rules You Must Know
Installment agreement issues run on their own clock. You have 30 days to appeal a rejection, a modification, a proposed modification, a proposed termination, or a termination. During that 30‑day window, and while a timely CAP appeal is pending, levy action is restricted by statute. A manager conference is not required for IA CAP appeals, though a discussion can still help clarify facts.
After A Seizure, Time Is Tighter
If a seizure already happened, you must appeal to the Collection manager within 10 business days of the Notice of Seizure. Move quickly, assemble proof of hardship or resolution, and request prompt Appeals review.
Common Reasons CAP Works
- The IRS used stale financial data that no longer reflects ability to pay
- A levy hit despite a pending, viable IA
- A lien filing would materially harm a refinancing that would pay the balance
- A seizure ignored new hardship facts or available alternatives These are exactly the issues CAP was designed to surface quickly.

Step By Step, A Reusable CAP Checklist
- Confirm the action type and deadline, lien, levy, seizure, IA decision, and calendar the exact due date.
- Request the manager conference where required, document the date and names, and note your intent to file within 2 business days.
- Assemble the packet, notice, identity, Form 2848 if represented, financials, action‑specific proof, and a one‑page chronology.
- Complete Form 9423, identify the action, write a numbered, evidence‑tied explanation, and propose a clear resolution.
- Submit to the Collection office or revenue officer on the notice, not to Appeals, and use certified mail or fax with confirmation.
- Track receipt, then prepare for an Appeals call within days or weeks, with exhibits ready to reference. During a timely CAP, collection normally stops unless collection is at risk.
FAQs
Does Form 9423 stop a levy immediately
Often, yes, when your CAP request is timely and accepted, collection normally stops while Appeals reviews the case, unless the IRS believes collection is at risk. The faster you meet the 2‑day intent and 3‑business‑day filing targets after a manager conference, the safer your position.
Where do I send Form 9423
Send it to the Collection contact on your notice, usually the revenue officer or local Collection office. Do not send it directly to Appeals or you risk delay. Use certified mail or fax and keep proof.
What if the IRS already seized property
You can still request CAP, but you must appeal to the Collection manager within 10 business days of the Notice of Seizure. Move fast and support hardship or alternative collection options.
Can I contest the underlying tax in CAP
No. CAP reviews the collection action, not the underlying liability, and its decision is final and not court reviewable. If you need court rights or to contest liability in a qualifying situation, consider CDP with Form 12153 within the notice’s 30‑day window.
What are the IA appeal time limits
You generally have 30 days to appeal rejected, modified, proposed for modification, proposed for termination, or terminated installment agreements, and levy action is restricted during that period and while a timely appeal is pending. A manager conference is not required for IA appeals.
Conclusion
If a lien, levy, or seizure threatens your client or your own business, Form 9423 under CAP gives you a fast, structured way to pause enforcement, present facts, and get an independent decision. Calendar the exact deadline, complete a manager conference where required, and submit to the Collection office on the notice, not to Appeals. In most timely cases, collection stops while Appeals reviews your file, and you will have an answer in days to weeks. For rights to petition Tax Court or to raise the underlying liability where allowed, consider CDP instead. Updated for December 20, 2025, based on current IRS sources.
