How to Respond to an IRS Notice: Step-by-Step Instructions

Learn how to respond to an IRS notice step-by-step, verify accuracy, gather documentation, and protect your rights while addressing tax issues.

Read the Notice Number First

Every IRS letter or notice has an identifier in the top-right corner — CP14, CP504, LT11, Letter 1058, CP90, or a four-digit number like Letter 3219. That code tells you exactly what the IRS is asking for and how much time you have. CP14 is a first balance-due notice with no immediate consequence beyond interest and penalties accruing. CP504 is a final notice before levy. LT11 / Letter 1058 starts the 30-day clock for Collection Due Process rights. CP3219A is the 90-day Statutory Notice of Deficiency.

Match the notice number against IRS Publication 594 or the IRS's online "Understand Your Letter" tool at irs.gov to see the standard meaning before you call anyone.

How to Respond Without Making Things Worse

Respond in writing within the window stated on the notice, even if your response is to ask for an extension. The IRS treats silence as agreement with their position. Use certified mail with return receipt — the IRS regularly loses correspondence, and your CMRR is the only proof of timely filing.

If you agree with the balance but can't pay, don't ignore the notice. Apply for an Installment Agreement at irs.gov/payments (Form 9465 for amounts the online tool can't handle) or request Currently Not Collectible status by submitting Form 433-F with documentation of monthly income and allowable expenses.

If you disagree, request your transcripts (Wage & Income and Account) before drafting a response. The IRS notice may be triggered by a 1099 or W-2 reported under your SSN but not on your return — in that case the fix is filing or amending the return, not arguing with the notice. Each notice type has its own appeal path; CP504 and LT11 give you Collection Due Process rights via Form 12153 if filed within 30 days.

Frequently Asked Questions

What should I do if I don't understand the IRS notice?

Start with the notice number printed in the top or bottom corner, then look it up on IRS.gov, which explains what each notice means and what it asks of you. Read the full letter to identify the tax year, the amount involved, and any response deadline. If the language is still unclear, a tax attorney or other qualified tax professional can review it with you and explain your options.

What if I can't pay the amount stated in the notice?

You still have options even when paying in full is not realistic right now. The IRS offers payment plans, including short-term arrangements and longer installment agreements, and in some situations taxpayers may qualify for an Offer in Compromise or a temporary delay in collection due to hardship. Because eligibility depends on your specific finances, consider speaking with a tax attorney about which option fits your situation.

What happens if I ignore the IRS notice?

Ignoring a notice generally makes the problem worse rather than making it go away. Interest and penalties can continue to build, and the IRS may move toward collection actions such as a federal tax lien or a levy on wages or bank accounts. Some notices also carry strict deadlines to dispute the IRS position, and missing them can cost you the chance to challenge the assessment.

Can I dispute the IRS notice if I disagree with their assessment?

Yes. If you believe the IRS is wrong, you can respond with a written explanation and supporting documentation by the date listed on the notice. Depending on the type of notice, you may have appeal rights through the IRS Independent Office of Appeals, and notices like a Notice of Deficiency give you a window to petition the U.S. Tax Court. A tax attorney can help you decide which path applies and prepare the response.

How long does it typically take to resolve issues raised in an IRS notice?

If the IRS notice includes a response deadline, ensure that you meet it. Failing to respond by the deadline could result in further complications, such as additional penalties and interest.
