I hear this regularly: "I got that lien letter months ago and didn't do anything. Is it too late?" Too late for a Collection Due Process hearing, probably. Too late to get Appeals to look at the lien? Usually not.
The law gives you two backup routes after the CDP window closes. Each has its own deadline, its own scope, and its own limits. Knowing the differences lets you pick the right one, or use both.
What you lost by missing the CDP deadline
Under Treasury Regulation 301.6320-1(c)(2), Q&A-C7, if you do not request a CDP hearing in writing within the 30-day period that begins the day after the five-business-day notification period, you forgo the right to a CDP hearing for the tax periods on that notice. Three things go with it:
- Tax Court review. A CDP determination can be appealed to the Tax Court under section 6330(d)(1). An equivalent hearing decision generally cannot.
- A required written determination on every statutory issue. You still get a written decision, but not a Notice of Determination that opens the courthouse door.
- Statutory suspension rules that apply to CDP hearings. More on that below, because it cuts both ways.
What you keep is the chance to have the Independent Office of Appeals consider your issues.
Route 1: the equivalent hearing
Treasury Regulation 301.6320-1(i) creates the equivalent hearing for taxpayers who did not make a timely CDP request. It is held by Appeals and "generally will follow Appeals' procedures for a CDP hearing." Instead of a Notice of Determination, Appeals issues a Decision Letter.
Deadline
Under Q&A-I7, you must submit a written request within the one-year period beginning the day after the end of the five-business-day period following the filing of the notice. Q&A-I9 says living outside the United States does not extend it. The timely-mailing rules of sections 7502 and 7503 apply under Q&A-I8.
The Appeals manual, IRM 8.22.5.3.2, now states that the one-year deadline for an equivalent hearing is subject to equitable tolling based on the facts and circumstances, if the taxpayer proves both diligence and extraordinary circumstances. Treat that as a last resort, not a plan.
Also note Q&A-C7: if you send a CDP request that turns out to be late, the IRS will notify you that it was untimely and offer an equivalent hearing, and you do not need to send a second request.
How to ask
Q&A-I1 requires a dated, written request with your name, address, daytime phone, taxpayer identification number, the type of tax, the tax periods, a statement that you are requesting an equivalent hearing with Appeals concerning the filing of the notice, your reasons for disagreeing, and your signature. Form 12153 is titled Request for a Collection Due Process or Equivalent Hearing, and it has a box for exactly this.
What Appeals considers
Q&A-I2: "the same issues that it would have considered at a CDP hearing on the same matter." That includes whether the IRS followed the rules, challenges to the appropriateness of the filing, spousal defenses, collection alternatives like withdrawal, subordination, discharge, an installment agreement or an offer, and, where allowed, the underlying liability. The full list is in what you can raise at a CDP lien hearing.
What you do not get
- No Tax Court review of the Decision Letter under section 6320 (Q&A-I6). The exception is a spousal defense under section 6015, which has its own 90-day Tax Court review rule.
- No suspension of the collection statute (Q&A-I3). The suspension in section 6330(e) applies only to timely CDP hearings.
- No required suspension of collection (Q&A-I4). The IRS decides case by case whether to pause collection, and Appeals may ask it to.
The second point deserves a closer look. A timely CDP request suspends the 10-year collection period while the hearing and any appeal are pending. An equivalent hearing does not. If your collection statute is running down, the equivalent hearing lets you be heard without adding time to the IRS's clock.
Route 2: the Collection Appeals Program
The Collection Appeals Program, or CAP, is a separate administrative appeal. According to IRM 5.12.6.4, collection actions appealable under CAP include lien notice filings, and CAP can also be used to appeal the denial of a request for withdrawal, discharge, subordination or nonattachment. CAP is available before or after the notice is filed. It is also available to third parties named on a special condition notice as nominees, alter egos, transferees or successors in interest.
How CAP works for liens
IRM 5.12.6.4.2 lays out the steps:
- You must first discuss the case with the Collection manager. The manager or designee must reply to your request for a conference within two workdays.
- If you do not reach agreement, you can request review by Appeals in writing, using Form 9423, Collection Appeal Request.
- Let the manager or revenue officer know within two business days after the manager conference that you intend to submit Form 9423. If you mail it, it must be postmarked within three business days of the manager conference to avoid collection action.
CAP moves fast. IRM 5.12.6.4.4 says Appeals tries to resolve CAP cases within 5 business days of the appeals officer receiving the case, with more complex cases normally resolved within 15 business days, and that decisions by Appeals are binding on the taxpayer and Collection. When the lien filing itself is the subject of the appeal, further lien action is generally withheld unless needed to protect the government's interests.
What CAP cannot do
IRM 5.12.6.4.1 lists exclusions. CAP cannot be used to appeal Collection's decision not to release a lien, an administrative appeal under section 6326 for an erroneously filed notice, or actions under the control of a court or the Department of Justice. Those have their own procedures. For an erroneous filing, see appealing an erroneous lien under section 6326.
Choosing between them
| Equivalent hearing | CAP | |
|---|---|---|
| Deadline | One year after the five-business-day period | Short windows tied to the manager conference |
| First step | Written request to the office on the CDP notice | Conference with the Collection manager |
| Scope | Same issues as a CDP hearing, including liability where allowed | The specific collection action or denial |
| Speed | No fixed time | Generally 5 business days; complex cases 15 |
| Judicial review | Generally none | Binding on taxpayer and Collection |
| Collection statute | Not suspended | The section 6330(e) suspension does not apply |
The equivalent hearing fits when you have several issues, need time to assemble financial information, or want to challenge the liability. CAP fits when you have one clean issue, such as a denied withdrawal request, and want a quick answer.
Do not forget the direct routes
An appeal is not the only way to deal with a filed notice. If you qualify, you can apply for withdrawal on Form 12277 at any time, without any hearing. You can request a certificate of release once the debt is paid or unenforceable. Start with the four grounds for lien withdrawal, and if the IRS says no, CAP is how you appeal the denial.
A practical sequence if you are past the 30 days
- Find the filing date. Your Letter 3172 shows the lien filing and the original response date. Count one year from the day after the five-business-day period. That is your equivalent hearing deadline.
- Decide what you want. Withdrawal, a payment arrangement, an offer, a correction of the assessment, or a spousal defense. Appeals responds to requests, not frustration.
- Get current. File any missing returns and make required estimated payments or deposits. The withdrawal criteria in IRM 5.12.9 repeatedly turn on filing compliance.
- Send a complete Form 12153 with the equivalent hearing box checked and a written explanation of your reasons, by certified mail.
- Keep CAP in reserve for a specific denial, such as a rejected withdrawal application, where a fast, binding answer is more useful than a broad hearing.
Missing the CDP deadline closes the courthouse door. It does not lock the building.
