Understanding your mail
IRS notices
The number in the corner of the letter tells you exactly where you are in the collection process. Most people never learn to read it. Here's the translation.
The basics
Read the corner first
An IRS notice or letter is official written correspondence about your tax account — it might state a balance due, propose a change to your return, or explain a collection action the IRS is taking or planning to take. The notice number matters more than the tone: two letters can describe a similar dollar amount and mean very different things, depending on where each one sits in the process.
Not every taxpayer’s situation follows the same sequence, and the instructions on the specific notice you received are what actually govern your case — this page explains the collection notices we see most often, but it’s not a substitute for reading your own letter carefully.
On any notice, look for the same handful of things: the notice or letter number (usually upper right), the tax year or period it covers, the amount involved, what it’s asking you to do, and the date by which it wants a response. Those five details determine what happens next.
CP14 — the first bill. A balance is due. Real, but early in the process.
CP501 — a first reminder, sent when an earlier notice went unanswered.
CP503 — a second reminder. The tone escalates further; continued non-response can lead to a federal tax lien filing.
CP504 — Notice of Intent to Levy. This one is serious: it permits the IRS to levy a state tax refund, and it signals that broader collection action — including a bank levy or wage levy — may be coming next.
CP90 — a final notice that also carries a Collection Due Process hearing right. The notice itself states your response deadline; we won’t guess at a number here since it should be read directly off your letter.
CP2000 — not a bill. A proposed change because reported income doesn’t match your return. Frequently wrong, and it has its own response deadline.
Final Notice of Intent to Levy and Notice of Your Right to a Hearing. It starts a 30-day window to request a Collection Due Process hearing. Miss the 30 days and you lose the strongest protection available to you.
Common situations
If you agree with the notice — the instructions on the letter generally cover paying in full by the due date, or setting up a payment plan if you can’t. See installment agreements for how a payment plan works.
If you disagree — most notices explain how to respond with documentation showing why you believe it’s wrong, and in many cases give you a window to request more time or an appeal. CP2000 is a common example of a notice that’s often incorrect and comes with its own response process.
If you can’t pay the amount shown — don’t let that stop you from responding. Not responding tends to move things further along the collection sequence, not pause it.
Why ignoring a collection notice creates problems — later notices in a sequence generally carry more serious consequences than earlier ones, up to and including a levy. Responding doesn’t resolve the underlying balance by itself, but it keeps your options open in a way that silence doesn’t.
When a notice may lead to collection action — CP504 and the Final Notice (LT11/Letter 1058) are the two that most directly signal levy risk. If a notice you received already references a levy on your wages or a bank account, wage garnishment help and bank levy help explain how each situation actually works.
What to have ready when asking for help
What’s needed depends on the notice and your situation — not everyone needs to bring the same things. In general, it helps to have:
- The complete notice or letter, if you still have it
- The notice or letter number and the tax year or period it covers
- The amount shown, if any
- Any other recent IRS correspondence related to the same balance
- Your filing status, including whether any returns are still outstanding — see unfiled tax returns if that applies to you
- Relevant payment or financial information, where it’s applicable to your situation

What helps
What matters here
These are the details that actually determine what happens next — not the tone of the letter.
The date, not the tone
Every notice has a response window. The deadline determines your options far more than how threatening the letter sounds.
Which notice it is
A CP14 and an LT11 describe similar amounts but sit in completely different places in the process.
Where it was sent
Notices go to your last known address. If you've moved, you may be deep in the sequence without having seen a single letter.
Our approach
How we handle it
Four steps, starting with the letter itself.
Identify and date it
Which notice, what deadline, how much time actually remains.
Verify against transcripts
Notices are sometimes wrong. Transcripts settle what's real.
Respond before the deadline
Including requesting a hearing where that right exists and it serves you.
Address the underlying balance
Answering the letter buys time; a resolution is what ends the sequence.
Notices are sometimes wrong, and responding to an incorrect balance can lock in a number that isn't real. We check the notice against your transcripts before we respond to it, not after.
Before you call
Who this isn't for
An audit notice, a Notice of Deficiency (90-day letter), or anything from IRS Criminal Investigation needs different expertise and, in some cases, a tax attorney. Call us and we'll point you in the right direction even if it isn't toward us.
Common questions
IRS notices questions
I got a notice but I already paid. What now?
Payments and notices cross in the mail routinely. Transcripts show whether the payment posted and where it was applied — sometimes to a different year than intended.
Can I ignore a notice if I can't pay?
Not safely. Ignoring notices moves you through the sequence toward levy. Responding without money is still far better than not responding — options exist for people who genuinely can't pay.
How much time do I have?
It depends on the notice. Some carry 30 days, some 21, some 90. The letter states it, and the date on the letter is when the clock started, not the day you opened it.
Is a CP2000 a bill?
No. It's a proposal, and it's often incorrect. You have the right to disagree with documentation.
What should I do when I receive an IRS notice?
Read the whole thing before reacting. Identify the notice or letter number, the tax year it covers, the amount involved (if any), what it's asking you to do, and the date by which it wants a response. Those five things determine what actually happens next — not how urgent the letter sounds.
What does the notice number mean?
It tells you where you are in the process and what the IRS is doing. A CP14 is an early bill; an LT11 or Letter 1058 is the final warning before a levy. Two letters can describe the same balance and mean very different things, so the code matters more than the tone.
What if I disagree with an IRS notice?
You generally have the right to respond with documentation explaining why you believe the notice is wrong, and in many cases the right to request more time or an appeal. The specific instructions for doing this are on your notice — follow those rather than assuming every notice works the same way.
What if I can't pay the amount shown?
Don't let that stop you from responding. Ignoring a notice because you can't pay in full tends to make things worse, not better. Depending on your situation, a payment plan may be an option — see installment agreements for how that works — or there may be other paths worth reviewing with someone before you decide.
Can an IRS notice lead to a bank levy or wage levy?
Yes, if it's part of a collection sequence that goes unresolved. Bank levies and wage levies work differently — see bank levy help and wage garnishment help for how each one actually works and what may address it.
What happens if I have unfiled tax returns?
It can limit your options. The IRS generally expects required returns to be filed before it will consider many resolution paths. See unfiled tax returns for how getting current usually works.
What information should I have ready when I call for help?
The notice itself, if you still have it, plus the notice number, the tax year involved, and the amount shown. Beyond that, it depends on your situation — someone reviewing your case may also ask about your filing status or income.
