The IRS sends millions of notices each year. Understanding which one you received and what it means is the first step toward responding effectively.
Common IRS notice types
- CP14: Balance due — you owe taxes and need to pay or set up a payment plan
- CP2000: Proposed adjustment — the IRS found a discrepancy between your return and reported income
- CP501/CP503/CP504: Reminder/Intent to levy — escalating collection notices
- LT11/LT1058: Final notice of intent to levy — serious collection action is imminent
- CP90/CP244: Final notice of intent to levy and notice of your right to a hearing
Important: IRS notices have response deadlines — typically 30–90 days. Ignoring a notice can lead to escalating collection actions, liens, or levies.
How to read an IRS notice
Every IRS notice includes: a notice number (top right), your tax year, a response deadline, and instructions. The notice number tells you what type of action the IRS is taking.
Steps to respond
- Read the entire notice carefully
- Note the response deadline immediately
- Gather supporting documentation
- Write a clear response letter addressing each item
- Mail certified with return receipt for proof of timely delivery
Tip: Certified mail with return receipt gives you a signed card back — physical proof that the IRS received your response.
