Short answer
IRS balance-due notices escalate from CP14 to CP501, CP503 and CP504, the notice of intent to levy under 26 U.S.C. § 6331(d). A final notice such as LT11, Letter 1058 or CP90 opens a 30-day window to request a Collection Due Process hearing under § 6330. CP2000 is a proposal, not a bill.
How the letters escalate
For an unpaid balance the ladder usually runs: CP14 → CP501 → CP503 → CP504 → LT11 / Letter 1058 or CP90, with levies and a public tax lien possible after that. Not every taxpayer receives every rung, and the IRS can move faster on some accounts. Correction letters (CP2000, CP21A, CP3219A) and missing-return letters (CP59, CP3219N) run on separate tracks.
The envelopes, one card each
Bill
CP14: Balance due
- Means
- The first bill: tax is owed on a filed return and was not paid.
- Clock
- Pay by the due date printed on the notice to limit added penalty and interest.
- First move
- Check the amount against the return. Pay, set up a plan, or call the number on the notice if it is wrong.
Bill
CP501: Reminder
- Means
- No payment or response arrived after the earlier notice.
- Clock
- Due date on the notice. The Collection Appeals Program is available.
- First move
- Same as CP14 — this is still the cheapest stage to act.
Bill
CP503: Second reminder
- Means
- The IRS still has not heard back and the balance remains unpaid.
- Clock
- Due date on the notice. The next notice is usually a levy warning.
- First move
- Respond now: pay, apply for a plan, or dispute by phone.
Levy warning
CP504: Notice of Intent to Levy
- Means
- Formal notice under IRC § 6331(d). The IRS says it can levy income and bank accounts and seize property, including a state income tax refund.
- Clock
- Treat as urgent. Further levies usually follow a final notice with hearing rights.
- First move
- Contact the IRS or have a representative do it; a pending payment-plan request generally stops levies.
Levy warning
LT11 / Letter 1058: Final notice of intent to levy
- Means
- The IRS intends to seize property or rights to property — wages, bank accounts, vehicles, Social Security benefits, even a home.
- Clock
- 30 days to request a Collection Due Process hearing (IRC § 6330). Also a passport-certification warning for large debts.
- First move
- Calendar day 30 now. File Form 12153 or get a plan in place before it passes.
Levy warning
CP90: Final notice — intent to levy
- Means
- Notice of intent to levy certain assets and of the right to a Collection Due Process hearing.
- Clock
- 30-day hearing window, same as LT11.
- First move
- Same urgency as LT11.
Levy warning
CP523: Intent to terminate a payment plan
- Means
- An installment agreement is in default; the IRS intends to end it and levy.
- Clock
- Contact the IRS no later than 30 days from the notice date.
- First move
- Make the missed payment before the termination date, or ask to reinstate.
Change or audit
CP2000: Proposed changes (income mismatch)
- Means
- Income or payments reported by employers, banks or 1099 payers do not match the return. Not a bill.
- Clock
- Reply by the date listed. No reply can lead to a bill.
- First move
- Compare every listed form with records; agree or disagree in writing with documents.
Change or audit
CP3219A: Statutory Notice of Deficiency
- Means
- The legal notice that lets the IRS assess the proposed tax unless it is contested.
- Clock
- 90 days. The IRS cannot extend the deadline to petition the U.S. Tax Court.
- First move
- Do not let the 90 days lapse if the change is wrong.
Change or audit
CP21A: Changes made to a return
- Means
- The IRS adjusted a return and an amount is now owed because of the changes.
- Clock
- Pay by the printed date if the change is right.
- First move
- Read what changed; if it is wrong, call the number on the notice.
Missing return
CP59: No return on file
- Means
- The IRS has no record of a prior-year return.
- Clock
- File immediately or explain why no return is required.
- First move
- Find out whether a return was required; if so, file it.
Missing return
CP3219N: Substitute return proposed
- Means
- The IRS built a return from third-party records for a year that was never filed — without the deductions a real return would claim.
- Clock
- 90-day letter.
- First move
- Filing an actual return for that year usually replaces the IRS version.
Who to call about a letter — compared
| Topic | Handle it alone | National call-center “relief” company | Licensed CPA, EA or CTRS (Ohio or Kentucky) |
|---|---|---|---|
| Cost | Free, plus time | Varies — ask what is charged before anyone has read the transcript | Quoted by the professional after a review |
| Can speak to the IRS for you | — | Only a credentialed person named on Form 2848 can | Yes, with a signed Form 2848 |
| Knows Ohio and Canton layers | Depends | Ask — many focus on federal balances only | Works with IRS, Ohio and municipal tax |
| Credentials checkable | — | Ask for the name and credential of whoever works the file | Yes — state CPA lookup, IRS directory, ASTPS |
| Best fit | A single CP14 that is correct and payable | Rarely the only option worth considering | Levy notices, multiple years, multiple layers |
Six steps for any IRS letter
- Find the notice code. It is printed on the notice, usually in a corner. Match it to a card above.
- Write down the response date. Every notice has one. For LT11, Letter 1058 and CP90 the 30-day hearing window counts from the notice date.
- Get the account transcript. Confirm which years and amounts the IRS shows before paying or disputing anything.
- Check for unfiled years. Most plans and every offer in compromise require all required returns to be filed.
- Choose a response. Pay, request a plan, dispute with documents, or request a hearing. Write down who was spoken to and when.
- Look for Ohio and Canton mail too. Collect state and city letters so all three layers are handled in one plan.
A CP2000 is the one letter on this list that is a proposal rather than a demand; it has its own walkthrough in the CP2000 underreported-income guide. If a balance-due letter is sitting next to a city or Ohio notice, the Canton guide to all three tax layers explains which usually moves first.

Call (330) 457-6198Questions people in Canton ask
Which IRS letter is the most urgent?
A final notice of intent to levy — LT11, Letter 1058 or CP90 — because it opens a 30-day window to request a Collection Due Process hearing (26 U.S.C. § 6330). A CP3219A is equally time-sensitive: its 90-day Tax Court deadline cannot be extended.
I got a CP2000. Do I have to pay it?
Not yet. A CP2000 is a proposal, not a bill. It shows third-party income that does not match the return. Reply by the date listed, agreeing or disagreeing with documentation. If there is no reply, the IRS may send a bill or a notice of deficiency.
Does a CP504 mean the IRS is taking my paycheck now?
Not by itself in most cases. A CP504 is the notice of intent to levy and lets the IRS levy a state tax refund. For most other levies, such as wages or a bank account, the IRS first sends a final notice with Collection Due Process hearing rights (LT11, Letter 1058 or CP90).
I have IRS letters and a City of Canton letter. Are they related?
No. The City of Canton Income Tax Department collects the 2.5% city tax separately from the IRS and from Ohio. A city letter never resolves an IRS balance, and an IRS plan does not cover city tax. See Canton city income tax.
How do I see what the IRS thinks I owe across all years?
Request an account transcript through an IRS Online Account or by mail. A licensed professional can read it with you, and with a signed Form 2848 can speak to the IRS for you.
