IRS Collection Notices in Order: The Complete Timeline

Here's the answer up front: for an unpaid tax balance, the IRS sends collection letters in this order — CP14 → CP501 → CP503 → CP504 → LT11 / Letter 1058, and only after that last one can it garnish wages or levy a bank account. Each letter is roughly five weeks after the one before it, so the whole run takes about four to six months — but the IRS can skip steps or pause for years, so the printed deadline on the letter you're holding is the only schedule that counts.

What follows is each stage in order: what the letter means, what the IRS can legally do at that point, and what's still available to you. The short version of the strategy is the same at every stage — everything gets harder and more expensive the further down the list you respond.

Stage 1: CP14 — the first bill

The CP14 is the IRS's opening move: you filed a return with a balance due, and it hasn't been paid. It shows the tax plus the penalties and interest accrued so far, and it starts the collection clock.

At this stage the IRS can't touch anything. Your full menu is open: pay it, set up an installment agreement (most balances under $50,000 qualify online in about 15 minutes), dispute a balance that's wrong, or send proof if you already paid. Penalties are also at their smallest and easiest to abate right now.

Stage 2: CP501 and CP503 — the reminders

The CP501 and CP503 are escalating reminders — same balance, growing interest, sterner language. Nothing new has legally happened, which makes these the most commonly ignored letters in the sequence. That's a mistake in slow motion: every option from the CP14 stage is still available, and the failure-to-pay penalty is compounding monthly while you wait.

One wrinkle: the IRS doesn't promise both reminders. Some accounts jump from CP14 territory straight to a CP504, especially on larger balances.

Stage 3: CP504 — intent to levy (state refund)

The CP504 is where words turn into consequences. It's labeled "Notice of Intent to Levy," and it authorizes the IRS to take one specific thing immediately: your state tax refund. It does not yet allow wage garnishment or a bank levy — that requires one more letter — but it's the signal that the account has moved to the front of the line.

This is the last comfortable moment to act. A payment plan set up now stops the sequence entirely; the same plan negotiated after a final notice happens under a 30-day countdown with your leverage draining.

Stage 4: LT11 / Letter 1058 — the final notice

The LT11 (or Letter 1058) is the letter the entire sequence has been building toward: Final Notice of Intent to Levy and Notice of Your Right to a Hearing. It starts a strict 30-day window to request a Collection Due Process (CDP) hearing on Form 12153. A timely request generally freezes levy action while an independent appeals officer hears your case — payment plan, Offer in Compromise, hardship status are all on the table there.

Miss the 30 days, and the IRS can levy without telling you anything else, ever. There is no per-levy warning after this letter.

Individuals may see this final notice as a CP90; businesses get the CP297. Social Security recipients may also receive a CP91, the final warning before the IRS takes 15% of each monthly benefit check.

Stage 5: the levy itself — Forms 668-W and 668-A

If the final notice's window closes unresolved, the paperwork stops going to you. A Form 668-W lands on your employer's desk and wage garnishment begins with the next payroll cycle — and unlike most creditors' garnishments, the IRS's formula leaves you an exempt amount and takes the rest. A Form 668-A goes to your bank, which freezes the funds in your account for 21 days and then sends them to the IRS.

Even here it's not over: levies get released every day when taxpayers get into an agreement or prove hardship — the release comes back as a Form 668-D. But you're now negotiating while your paycheck is short, which is exactly the position the earlier letters existed to keep you out of.

The detours: letters that join the sequence sideways

Not every account walks the main road. The common branches:

• LT16 and LT39 — the account is in the Automated Collection System (ACS). LT16 asks you to call about a balance and/or unfiled returns within 10 days; LT39 is a balance reminder. Both slot in around the reminder stages, and both mean a computer is actively working your file.
• LT38 — the sequence was paused (as it was for millions of accounts in recent years) and is now resuming. Treat it as a restarted clock, not a fresh start.
• CP71C — the annual statement on an old balance. The sequence may be dormant; the debt is not.
• CP523 — you had an installment agreement and defaulted it (missed a payment, new unpaid balance, or unfiled return). You have 30 days to cure it before the agreement terminates and the account rejoins the collection sequence — already at the levy end. The routine monthly CP521 reminder is how you avoid ever seeing one.
• CP2000 → CP3219A — the assessment track that runs before collection: proposed changes from income matching, then a Statutory Notice of Deficiency with 90 days to petition Tax Court. Ignore both and the resulting balance enters the collection sequence at CP14 with its own head of steam.
• Business accounts — a CP161 balance due (often payroll tax) escalates toward the CP297 final notice, with the added hazard that unpaid trust-fund taxes can be assessed personally against owners and officers.

How much time you really have

Roughly five weeks per letter is the pattern, but treat that as trivia, not planning material. The IRS skips reminders on some accounts, pauses sequences for staffing and policy reasons, and resumes them without warning. Two rules replace the guesswork:

1. The deadline printed on the notice is real. Everything else is an estimate.
2. Your position never improves by waiting. Penalties compound monthly, and each stage removes an option the previous stage offered.
