IRS Notice Decoder

Paste any IRS or state notice — get a plain-English explanation, the real deadline, your options, and a draft response you can adapt. An assistant for your firm, not a substitute for your judgement.

Processed transiently, never stored. Remove SSNs & personal IDs before pasting.

AI-generated guidance for triage only — verify against the actual notice and your client's facts before acting. Not legal or tax advice.

What Does Your IRS Notice Actually Mean?

Getting a letter from the IRS is unsettling, but most notices are routine and fixable. This IRS notice decoder reads the notice you paste in and gives you a plain-English explanation — what does CP2000 mean, what a CP14 wants — plus the deadline, your options, and a draft response to start from.

It's built for CPA and accounting firm staff triaging client mail, and for taxpayers who want an IRS letter explained before they call anyone. It's a triage tool, not a substitute for a licensed CPA or tax attorney — it tells you how urgent the notice is and what to look at next.

How to Use the Decoder

  1. Find and paste the notice text. Copy the body of the letter into the box — remove Social Security numbers and other account numbers first.
  2. Read the plain-English summary. The decoder translates the IRS's language into a short explanation of what's being said and why the notice was sent.
  3. Check the deadline and your options. Every response window is different — the tool surfaces the date you need to act by and the choices available.
  4. Use the draft response as a starting point. It's a template, not a final filing — verify it against the client's records and the notice itself before sending anything to the IRS.

Where to Find Your Notice Number

Every IRS notice and letter carries an identifying code, usually in the top-right or bottom-right corner of the first page — formats like "CP2000" or "Letter 5071C" are common. Locate it before pasting the notice in; it's the fastest way to gauge how serious the letter is and how much time you have.

Common IRS Notices, Explained

CP14
The IRS's first bill for unpaid tax, showing the balance due plus interest and penalties, and a date to pay or arrange payment.
CP2000
An underreporter notice proposing changes because income reported by third parties (W-2s, 1099s) doesn't match your return. A proposal, not a bill — usually 30 days to agree or disagree.
CP2501
An earlier-stage underreporter notice, sent before specific changes are proposed. A timely response can prevent a CP2000 from following.
CP501 / CP503
Escalating reminders that a balance from an earlier bill is still unpaid, each more urgent than the last.
CP504
Notice of intent to levy your state tax refund if the balance isn't resolved — a sign further collection is coming.
LT11 / Letter 1058
The Final Notice of Intent to Levy, with your right to a Collection Due Process (CDP) hearing — generally 30 days to request it.

Not every notice is about a balance due. Letters like 5071C, 4883C, and 5747C are identity-verification requests — confirming it's really you before the IRS processes a return or refund, with no tax proposed at that stage.

How to Respond to an IRS Notice

  • Note the deadline first. Windows commonly run 30 or 60 days, and collection notices like LT11 have hard deadlines that forfeit appeal rights if missed.
  • Verify the notice against your records. Confirm the IRS's numbers against the return, W-2s, 1099s, or payment history first.
  • Agree or dispute with documentation. Notices like CP2000 let you agree, partially agree, or disagree — a disagreement needs supporting documents.
  • Respond in writing and keep copies. Send a written response even if you also call, and keep proof of what was sent.
  • Use certified mail. A return receipt proves what was sent and when, which matters if a deadline is later disputed.
  • Get professional help for levies, appeals, or penalty abatement. Route anything involving a CDP hearing or penalty removal to a CPA or enrolled agent.

Frequently Asked Questions

What does a CP2000 notice mean?
It means income or other amounts on your return don't match what employers, banks, or other payers reported to the IRS on forms like W-2s or 1099s. It's a proposed change, not a final bill — you can agree, partially agree, or disagree with documentation, typically within 30 days.
How long do I have to respond to an IRS notice?
It depends on the notice — many give 30 or 60 days, printed on the notice itself. LT11 and Letter 1058 carry a firm 30-day window to request a Collection Due Process hearing, and missing it can forfeit appeal rights.
Is an IRS notice the same as an audit?
No. Most notices, including CP2000 and CP14, are generated automatically by computer matching, not by an examiner opening an audit. A notice can still lead to further review if unresolved, but receiving one doesn't mean you're being audited.
What happens if I ignore an IRS notice?
It typically escalates — a balance-due notice moves through reminders like CP501 and CP503 toward CP504 and eventually a Final Notice of Intent to Levy, after which wages, bank accounts, or refunds can be levied.
Can I dispute an IRS notice?
Yes, for most notices. Respond in writing with supporting documentation explaining your disagreement — CP2000 has a specific dispute process. Collection notices tied to a levy also carry appeal rights, such as a CDP hearing, if requested by the deadline.
Is this tool a substitute for a tax professional?
No. This decoder is a triage assistant that helps you understand a notice faster and draft a starting response — it is not legal or tax advice and doesn't replace a licensed CPA or tax attorney. Verify any draft against your records, and involve a professional for levies, appeals, or penalty abatement.
