I Received an IRS Letter — What To Do

Don't panic. Here's how to read it, what the codes mean, and when you actually need professional help.

Don't panic — most letters are routine

The IRS sends 210 million notices a year. Most are about simple issues: a math error on your return, a missing payment, or a request to verify your identity. An IRS letter is not the same as an audit. Read it carefully, note any deadlines, and respond if required.

Find the notice number

Every IRS letter has a notice number in the upper right corner (like CP2000, CP14, LT11). This tells you exactly what the letter is about. Look up your notice code in our IRS Notice Library for a plain English explanation of what it means, how serious it is, and what to do.

Respond by the deadline

If the letter gives you a deadline, meet it. Ignoring IRS notices escalates the situation — from gentle reminders to levy threats. Most notices give you 30-60 days to respond. Even if you can't fully resolve the issue, responding shows good faith and prevents escalation.

When to get professional help

You can handle most CP notices yourself. But consider a tax professional if: the notice involves more than $5,000, you received a CP90/LT11 (levy notice), you got a CP3219A (statutory notice of deficiency with 90-day Tax Court deadline), or you don't understand what they're asking for. Tax relief companies charge $3,000-$10,000 for services you might be able to do yourself — try understanding it first.
