Don't Panic — You Have Options
Receiving an IRS notice is stressful, but with the right help, most notices are resolved without litigation.
Critical IRS Notice Categories and What They Mean
Understanding which type of notice you have received is the first step toward an effective response.
CP Notices — Computer-Generated
CP notices are the most common IRS correspondence. CP14 is a balance-due notice, CP2000 proposes adjustments for unreported income, and CP501/503/504 are escalating collection reminders. Most CP notices give you a specific window to respond — typically 21 to 30 days.
- Identify the CP number in the upper-right corner
- Each CP number maps to a specific issue
- Response windows vary by notice type
LT Letters — Escalated Collection
LT (Letter) notices are generally more serious than CP notices. The LT11 is the Final Notice of Intent to Levy — it gives you 30 days to request a Collection Due Process hearing. The LT1058 notifies you of lien filing and CDP rights. LT notices demand immediate attention.
- LT11: Final Notice before levy — 30 days to act
- LT1058: Lien filing notice with CDP rights
- These are among the most urgent IRS notices
Notice of Deficiency — 90-Day Letter
A statutory Notice of Deficiency (often called a 90-day letter) is a formal legal notice that the IRS has determined a deficiency in your tax. You have 90 days to petition the U.S. Tax Court. Missing this deadline means you lose your right to challenge the IRS's determination in court.
- 90-day window to petition Tax Court
- Formal legal notice with statutory deadline
- Losing this deadline forfeits court review
Final Notice of Intent to Levy
The LT11, CP90, and CP91 are final levy notices. They mean the IRS intends to seize your bank accounts, garnish your wages, and levy your property. You have 30 days from the date of the notice to request a Collection Due Process hearing — which puts enforcement on hold while Appeals reviews your case.
- 30-day deadline is absolute — do not miss it
- CDP hearing request stops enforcement
- Professional representation strongly recommended
Every IRS notice has a deadline. Missing it can cost you your right to appeal — or trigger enforcement action.
IRS notices are not optional reading. Each notice carries a specific response deadline — usually 21, 30, or 90 days from the date printed on the notice. Missing that deadline can have serious consequences:
- A missed CP2000 deadline means the IRS will issue a statutory Notice of Deficiency, and your dispute options narrow significantly.
- A missed LT11 or CP504 deadline means the IRS can proceed with bank levies, wage garnishments, and property seizure — without further notice.
- A missed 90-day Notice of Deficiency deadline means you permanently lose your right to petition the U.S. Tax Court.
- A missed CDP hearing request deadline means you lose the right to an independent Appeals review before enforcement.
If you have an IRS notice and are unsure of your deadline, contact us immediately for a free review. We will identify your deadline and explain your options.
Common IRS Notices by Severity Level
From informational to urgent — here are the notices we most frequently help clients understand and resolve.
Informational — CP01, CP03, CP05
These notices are informational only. CP01 confirms your identity protection PIN. CP03 confirms your tax return has been received. CP05 informs you that your refund is being held pending a 60-day review. No action is required, but they should be retained for your records.
Request/Proposal — CP2000, CP2501
These notices propose changes to your return. A CP2000 says third-party income doesn't match your return. A CP2501 is a preliminary inquiry. Both require a response — either agreeing and paying, or disputing with documentation. Deadline: typically 30 days.
Collection Escalation — CP501, CP503, CP504
The CP501 is a first reminder. The CP503 is an urgent second reminder. The CP504 warns the IRS intends to levy state tax refunds and federal payments — and that the Final Notice of Intent to Levy is imminent. By CP504, enforcement is around the corner.
Enforcement Imminent — LT11, LT1058, CP90, CP91
These are final notices before enforced collection. The IRS intends to levy your bank accounts, wages, and property. You have 30 days to request a Collection Due Process hearing. This is the last opportunity to stop enforcement through an independent appeals review.
How We Handle Your IRS Notice
Our proven six-step process ensures every notice is reviewed, verified, and responded to correctly — protecting your rights at every stage.
Notice Intake & Triage
We review your notice, identify the CP or LT number, confirm the tax period, note the deadline, and assess the urgency level — within hours, not days.
Same Day
Fact Verification
We cross-check the IRS's claims against your tax records, payment history, IRS transcripts, and third-party data to determine whether the notice is accurate.
1-3 Days
Compliance Review
We verify all required returns are filed and request any missing transcripts. Unfiled returns often trigger or worsen notice issues — we bring your filing status current.
2-5 Days
Response Strategy
We develop the optimal response — correction, dispute, payment plan proposal, CDP hearing request, appeal, or full payment — based on the facts and your goals.
3-7 Days
IRS Communication
With your power of attorney (Form 2848), we handle all correspondence with the IRS — submitting responses, following up, and negotiating resolution terms.
Ongoing
Resolution & Closure
We confirm the issue is resolved, obtain IRS closure letters or confirmation records, and provide you with clear documentation showing the matter is settled.
Case Dependent
Ignoring an IRS Notice vs Responding Professionally
The difference between ignoring a notice and responding with professional help is the difference between enforcement and resolution.
Information We Need From Your Notice
Having these items ready helps us respond to your IRS notice quickly, accurately, and with the best possible outcome.
The IRS notice — all pages, front and back
Photocopy or scan the entire notice. Do not omit any pages — important information and deadlines may appear on the reverse side.
Any envelope the notice came in
The postmark can establish when you received the notice, which may be relevant for deadline calculations and CDP hearing requests.
Prior IRS notices for the same tax period
Bring any earlier notices about the same issue. The sequence of notices tells us where you are in the IRS escalation pipeline.
Your tax return for the period in question
We need to compare what you filed against what the IRS is claiming — discrepancies often drive notice issues.
All income statements — W-2s, 1099s, K-1s
For CP2000 and underreporting notices, we need all third-party income documents to verify or dispute the IRS's figures.
Records of any IRS payments made
Proof of payment can resolve balance-due notices where the IRS has not yet credited your payment — a surprisingly common issue.
IRS account transcript (if available)
The transcript shows the IRS's internal record of assessments, payments, penalties, and notices — invaluable for verifying accuracy.
Prior correspondence with the IRS about this issue
Any letters, faxes, or call notes from previous interactions help us avoid duplication and understand what has already been attempted.
Documentation supporting deductions or credits claimed
If the notice disputes deductions or credits, we need receipts, logs, and supporting records to substantiate your position.
Bank statements showing IRS payments or refunds
Canceled checks and bank records provide independent verification of payments the IRS may not have properly credited.
Your most recent pay stubs and financial summary
If you cannot pay in full, this information supports a payment plan, hardship status, or Offer in Compromise request.
Signed Form 2848 — Power of Attorney
This authorizes us to represent you before the IRS. We prepare it; you sign. Without it, the IRS will not speak with us about your case.

IRS Notice Decision Tree
Answer these questions to understand your situation.
1. Is the IRS notice informational only (no balance due, no deadline)?
If it's a CP01, CP03, or CP05, the notice is informational — keep it with your tax records, but no response is required. You can call to confirm if you are unsure.
If the notice requests action, payment, or a response, move to the next question — your notice requires attention by a specific deadline.
2. Is the amount on the notice accurate based on your records?
If the IRS's numbers are correct and you can pay, send the payment with the response form. If you cannot pay in full, contact us — payment plans and settlement options are available.
If the IRS's figures are wrong, you need to respond with documentation showing why. A professional can help you draft an effective response that the IRS will accept.
3. Is the notice a CP2000 or CP2501 (underreporting inquiry)?
These are proposed adjustments — not final bills. You have 30 days to agree or dispute. Responding with documentation is critical; ignoring it leads to a Notice of Deficiency and far fewer options.
If the notice is a balance-due or collection notice, it is more urgent. Move to the next question to determine how close you are to enforcement.
4. Is the notice labeled LT11, CP504, CP90, CP91, or Final Notice of Intent to Levy?
These are the most urgent notices — the IRS is about to levy your bank accounts or garnish your wages. You have 30 days to request a Collection Due Process hearing, which stops enforcement while Appeals reviews your case. Call us immediately.
If it's an earlier-stage notice (CP14, CP501, CP503), you still have time, but do not wait — penalties and interest accrue daily, and the IRS escalation pipeline eventually reaches enforcement.
5. Have you already missed the response deadline printed on the notice?
Do not assume it is too late. In many cases, you can still respond, appeal, or negotiate — especially with professional representation. Contact us for a free case review; we have helped clients at every stage.
If your deadline has not passed, act now. Gather your notice, tax return, and supporting documents and contact a professional. Responding before the deadline preserves your rights and gives you maximum flexibility.

CP2000 Underreporting Dispute
Problem
A client received a CP2000 proposing an additional $18,000 in tax based on unreported 1099 income from a former employer that had issued an incorrect form.
Resolution
We gathered the client's original pay stubs and W-2, filed a detailed dispute with supporting documentation, and the IRS accepted the correction. The proposed assessment was reduced to zero.
LT11 Final Notice — Levy Stopped
Problem
A small business owner received an LT11 Final Notice of Intent to Levy with only 20 days remaining on the 30-day window. The IRS was preparing to levy business bank accounts.
Resolution
We filed a Collection Due Process hearing request the same day, stopping all enforcement action. We then negotiated an Installment Agreement that the client could afford, preserving the business operations.
90-Day Letter — Tax Court Petition
Problem
A client received a Notice of Deficiency asserting a $42,000 deficiency with only 14 days remaining in the 90-day period. The client had been ignoring IRS mail for months.
Resolution
We filed a Tax Court petition before the deadline, preserving the client's right to judicial review. The case was settled with IRS Appeals for less than 20% of the asserted deficiency after we presented documentation the IRS had overlooked.

Frequently Asked Questions About IRS Notices
An IRS notice is a written communication that can be informational, a request for information, a proposed adjustment, or a demand for payment. Not all notices are bills — many are simply letting you know that something has changed or that the IRS needs more information. A bill, on the other hand, specifically demands payment by a certain date. Notices like the CP14 (first balance-due notice) function as bills, while notices like the CP2000 (underreporting inquiry) are proposals — not bills. Understanding the difference is essential to knowing how to respond.
First, do not ignore it. IRS notices have deadlines, and ignoring a notice does not make the problem go away — it makes it worse. Open the notice, note the notice number (CP or LT number), the tax period it refers to, and any deadlines listed. Then contact a tax professional who can help you understand what the notice means, whether it is correct, and what your response options are.
The IRS initiates most contact through the U.S. mail — not by phone, email, or text message. A legitimate IRS notice will include your taxpayer identification number (usually partially redacted), the tax period in question, a specific notice number (such as CP14 or LT11), and instructions for responding. If you receive a call claiming to be the IRS demanding immediate payment via gift cards, wire transfer, or cryptocurrency, it is a scam. When in doubt, contact a tax professional to verify the notice before taking any action.
It depends on the notice. A CP2000 (underreporting inquiry) typically gives you 30 days to respond, with extensions available. A CP14 (balance due) asks for payment within 21 days to stop additional interest and penalties. A CP504 or LT11 (Final Notice of Intent to Levy) gives you 30 days before the IRS can levy. CDP hearing requests must be postmarked within 30 days of the date on the lien or levy notice. Always read the notice for the specific deadline — these vary.
The IRS does not stop with one notice. If you ignore the initial notice (such as a CP14), the IRS will escalate through its collection pipeline — sending increasingly urgent notices, and eventually issuing a Final Notice of Intent to Levy, filing a federal tax lien, and proceeding with enforced collection such as bank levies and wage garnishments. Each notice you ignore reduces your options and increases the urgency. The best time to respond is with the first notice.
If you have lost your notice, you can request a copy from the IRS by calling the number on any prior IRS correspondence or by requesting your IRS account transcript online at IRS.gov. The transcript will show recent notices, any balance due, and payments made. If you are unsure of the notice number or tax period, a tax professional can investigate on your behalf using a power of attorney (Form 2848) and identify any outstanding notices that need attention.
Yes, you can call the IRS directly using the phone number on your notice. However, be prepared for long hold times — often 30 minutes to an hour or more — and understand that the IRS representative's job is to collect the amount the IRS believes you owe, not to help you explore resolution options or negotiate. A tax professional with a valid power of attorney can call designated practitioner priority lines, often getting through faster, and has the experience to negotiate resolution terms that the IRS may not volunteer. Whether to call yourself or have a professional handle it depends on the complexity of your notice and your comfort level with IRS procedures.
A CP2000 is a notice of proposed adjustment — the IRS believes income reported on your tax return does not match information it received from third-party payers such as employers, banks, and brokerages. It is not a bill; it is a proposal. You have the right to agree or disagree. If you agree and the IRS's figures are correct, you can sign and return the response form and pay the proposed amount. If you disagree, you must respond with documentation showing why the IRS's information is incorrect. Ignoring a CP2000 will result in the IRS issuing a statutory notice of deficiency, after which your options narrow.
