Understanding IRS Notices: What They Mean and How to Respond

Receiving a letter from the IRS can feel stressful, but not every notice signals a serious problem. Many are informational, some require a simple response, and others outline next steps for resolving a balance or updating your account. Understanding what these notices mean can help you take timely, confident action without feeling overwhelmed.

This guide explains the most common types of IRS notices, what they typically indicate, and how to move forward calmly and effectively.

Why You Receive an IRS Notice

The IRS issues notices for many reasons, including:

• Missing or unfiled tax returns
• A balance due
• A change to a previously filed return
• A request for additional information
• Confirmation of a payment plan
• Identity verification
• Updates to your account status

Notices will always explain why they were sent and what action, if any, you must take.

Common IRS Notices and What They Mean

CP14 – Balance Due Notice

This is one of the most common IRS letters. It indicates the IRS believes you owe a balance for a specific tax year. The notice outlines the amount owed, due dates, and how penalties or interest may apply.

CP501 / CP503 – Reminder Notices

These notices follow a CP14 when a balance remains unpaid. They serve as reminders and may include updated amounts due.

CP504 – Notice of Intent to Levy (Not a Final Levy Notice)

A CP504 warns that the IRS may levy a state refund or take further collection steps if the balance is not addressed. Although not a final levy notice, it requires prompt attention.

LT11 / Letter 1058 – Final Notice of Intent to Levy

This is the final notice before the IRS may levy certain assets or wages. It also informs you of your right to a Collection Due Process (CDP) hearing.

CP2000 – Underreported Income

This notice proposes changes when the income reported on your return does not match information provided by employers, banks, or other institutions.

Identity Verification Notices (5071C, 6331C, 4883C)

These notices request confirmation of your identity before the IRS processes your return.

What To Do When You Receive an IRS Notice

Read the Notice Carefully

IRS notices outline the issue, the tax year involved, and any required actions. Carefully reviewing the letter helps determine next steps.

Check for Accuracy

Mistakes happen. Compare the notice to your filed return, financial records, and withholding history to ensure the information is correct.

Review Your IRS Account Transcripts

Transcripts offer insight into your account status, past filings, penalties, and payments. Reviewing them can help clarify the situation before responding.

Respond Promptly

Some notices require no action, others require a response, and some involve deadlines. Timely action helps avoid unnecessary escalation.

Avoid Ignoring Collection Notices

Not all notices are urgent, but delaying responses to balance-due or levy notices can lead to complications. Moving quickly helps keep more options open.

When Professional Help Can Make a Difference

Complex notices, large balances, or discrepancies often benefit from working with a licensed professional. An Enrolled Agent can:

• Review and interpret your notice
• Request transcripts
• Communicate with the IRS on your behalf
• Evaluate relief options
• Help prepare missing returns
• Prevent escalation into enforced collection
