What a CP90 is
A CP90 is the Final Notice of Intent to Levy. The IRS's own description: "We intend to levy certain assets for unpaid taxes and are informing you of your right to a Collection Due Process hearing."
It is the letter section 6330 of the tax code requires before the IRS may levy your wages, bank account or other property — written notice of your right to a hearing, at least 30 days beforehand.
Why the codes differ, and when it matters
The IRS issues this notice under several labels; these are the four you are most likely to be holding. The Taxpayer Advocate Service lists all of them among the notices that carry Collection Due Process rights, under near-identical titles.
| Code | Issued by | Rights |
|---|---|---|
| CP90 | The campus processing an individual account | 30 days, Form 12153 |
| LT11 | The automated collection system | 30 days, Form 12153 |
| Letter 1058 | A revenue officer assigned to your case | 30 days, Form 12153 |
| CP297 | The campus processing a business account | 30 days, Form 12153 |
Three of these four differences are administrative and change nothing you would do. The fourth does: a Letter 1058 means a person has your file, with discretion, deadlines of their own, and the ability to visit. That is a genuinely different next few weeks, and it has its own page.
Reference: every code that carries this right, and which are which
Skip this unless your letter carries a code that is not CP90 — the answer for CP90 is above.
If you only need one line of this: if your letter says the IRS intends to levy, nothing has been taken and your window is running. If it says levied or seizure, something has been taken and the window is still running. That is the whole distinction, and the tables below are for the reader who wants to see their exact code in it.
The Taxpayer Advocate Service lists fifteen notices and letters as carrying Collection Due Process rights, and they divide into those two groups.
Group one — the IRS intends to levy. The hearing comes first.
| Code | The IRS's own title | Typically |
|---|---|---|
| LT11 | Notice of Intent to Levy and Your Notice of a Right to a Hearing | Automated collection |
| Letter 1058 | Final Notice, Reply Within 30 Days — Notice of Intent to Levy and Notice of Your Right to a Hearing | A revenue officer |
| CP90 | Final Notice, Notice of Intent to Levy and Notice of Your Right to a Hearing | An individual account |
| CP297 | Final Notice — Notice of Intent to Levy and Notice of Your Right to a Hearing | A business account |
| CP177 | Intent to Seize Your Assets and Notice of Your Right to a Hearing | — |
| CP77 | Final Notice — Notice of Intent to Levy | Note: this title carries no hearing-rights half |
| Letter 4066 | Notice of Intent to Levy and Notice of Your Right to a Hearing | — |
Group two — the IRS has already levied. The hearing comes after.
| Code | The IRS's own title | What has happened |
|---|---|---|
| CP90C | Final Notice of Intent to Levy and Notice of Hearing | Assets levied; the specimen's printed heading reads "Notice of seizure and notice of your right to a hearing" |
| CP92 | Notice of Levy on State Refund — Notice of Your Right to a Hearing | Your state tax refund taken |
| CP242 | Notice of Levy on Your State Tax Refund — Notice of Your Right to a Hearing | The same |
| CP297A | Printed heading: Notice of seizure and notice of your right to a hearing | Business assets, after a disqualified employment tax levy |
| CP297C | The same | Business assets, after a federal contractor levy |
| LT75 | Notice of Levy and your rights to a Hearing (Federal Contractor) | A federal contractor levy |
| Letter 2439 | Notice of Jeopardy levy and Right of Appeal | A jeopardy levy |
One code on the TAS list is neither, and it matters. A Letter 3174, "New Warning of Enforcement," is a re-warning rather than a fresh right. The regulation is explicit that only the first CDP notice for a tax and period entitles you to a hearing — 26 CFR 301.6330-1 — and the IRS sends a new warning when no collection action has followed within about six months. If you are holding one, the date that matters is the date of the Final Notice that came before it, and what is usually still open is an equivalent hearing. The same is true of anything that arrives after a Final Notice you have already had.
Why group two exists at all, because it looks like a mistake and it isn't. Section 6330 of the tax code says no levy may be made until the IRS has notified you in writing of your right to a hearing. Section 6330(f) then carves out four situations — a jeopardy finding, a levy on a state tax refund, a disqualified employment tax levy, and a federal contractor levy — where that requirement does not apply. In each of those the same subsection still entitles you to a hearing, within a reasonable period of time after the levy. The carve-out moves the hearing; it does not remove it. Group two is what that looks like in your mailbox.
So the useful question is not which code you have. It is which group. If it says intend, your window is running and nothing has been taken. If it says have levied or seizure, something has been taken and the window is still running — CP90C if it is assets, CP92 if it is your state refund.
And one caution about the whole table. Being on it means the code has at some point carried a hearing right. It does not mean your particular letter still does: the right attaches once per tax period, so a second notice for a year you have already had one on is a reminder rather than a new window.

Your clock
30 days from the date printed on the notice to request a Collection Due Process hearing, on Form 12153.
Before you decide anything, pull the account transcript for the years on the notice — it is free, you can request it yourself, and it is the only place the other live dates are recorded. Reading it is the harder part. How to pull IRS transcripts without calling →
Counted from the date on the letter — not from the day it arrived. The regulation at 26 CFR 301.6330-1 is explicit that actual receipt is not a prerequisite: a notice sent to your last known address starts the clock whether or not it reaches you.
What the hearing gets you, and what it costs
A Collection Due Process hearing is not an appeal against the tax. It is a hearing about the collection of it, in front of the IRS Independent Office of Appeals, and what it practically does is put a stop between you and a levy while somebody neutral looks at whether the collection action is appropriate and whether a less intrusive alternative would work.
Publication 1660: "Unless one of the exceptions in section 6330(f) applies… levy action is not permitted for the subject tax and periods during the 30 days after the levy notice and during the timely requested CDP hearing process."
And the cost, which almost nobody mentions. The same publication: "If your request for a CDP hearing is timely, the 10-year period the IRS has to collect your taxes will be suspended until the date Appeals' determination becomes final or you withdraw your request for a hearing in writing." The IRS generally has ten years from assessment to collect; a timely request pauses that clock. For most people that is a good trade. If your balance is old, it is one to make deliberately.
If the 30 days has already gone
An equivalent hearing is available for one year from the date of the levy notice, on the same form. It is a lesser thing in three specific ways, and all three have to be said together:
| CDP hearing | Equivalent hearing | |
|---|---|---|
| Levy action | Not permitted during the 30 days and the hearing, narrow exceptions aside | Not prohibited. Appeals may ask for a hold; nothing obliges it |
| Suspends the collection period | Yes | No |
| Can be taken to Tax Court | Yes | No |
