IRSLetterDecoded
An unpaid tax bill climbs a fixed staircase of letters. Each one is scarier than the last, and each one is also a door — a chance to pay, to dispute, to ask for time, or to use a right that expires at the next step. Here is the whole staircase, so the letter in your hand stops being a mystery and becomes a position.
| Step | The letter | What it means | Your clock |
|---|---|---|---|
| 1 | CP14 | The first bill. Interest and the failure-to-pay penalty are already running. | Pay by the date printed (about 21 days) |
| 2 | CP501 | A reminder, roughly five weeks later. | The date printed |
| 3 | CP503 | A sterner demand — 'immediate action required.' | About 10 days asked |
| 4 | CP504 | Notice of intent to levy — aimed at your state tax refund. Not the final notice; no hearing rights yet. | The date printed |
| 5 | Letter 3172 | The IRS has filed (or will file) a public tax lien. Your one chance to appeal it. | The request-by date printed — about 30 days |
| 6 | LT11 / Letter 1058 | The final notice. Intent to levy, with your right to a Collection Due Process hearing. | 30 days — the most valuable clock in tax mail |
| 7 | The levy itself | Bank accounts (after a 21-day hold), wages (continuous), state refunds, and up to 15% of Social Security via the automated program. | — |
At every step, the same doors stand open: pay (in full or by plan), dispute (the bill is sometimes simply wrong), pause (hardship status stops enforcement while the 10-year collection clock keeps running in your favor), and appeal (the hearing right at the final notice, the manager-level appeal everywhere else). The steps only close doors behind you — the hearing right dies at step 6 if the 30 days pass unused.
The IRS generally has 10 years from the day a tax was assessed to collect it (26 U.S.C. § 6502). When the 10 years run out, the debt expires by law. Some choices pause that clock — a hearing request, an Offer in Compromise, bankruptcy — which is why the honest math matters before you file anything. The Kit's ladder map lays the pauses out in one picture.
The free decoder tells you what the letter means and when it is due. The Kit is the doing: response letters for every notice family, the penalty-relief scripts, the payment-plan and Offer in Compromise reality checks, and the proof habits that keep a sent letter from becoming a lost argument.

No — and the confusion is expensive. The CP504 announces intent to levy your state tax refund. The final notice that carries hearing rights is the LT11 or Letter 1058. Treating the CP504 as 'the last letter' wastes the calm before the real deadline.
Months, usually — the reminder steps are spaced weeks apart, and accounts move between the automated system and human officers. But 'usually months' is not a strategy: penalties and interest compound the whole way, and the final steps can arrive faster than the early ones suggest.
Sometimes — a levy causing immediate economic hardship can be released, and money taken within the bank's 21-day hold can still be reached. Prevention is unrecognizably cheaper than reversal, which is the entire argument for answering letters at step 1 instead of step 6.
