Quick answer
What should you do after receiving an IRS notice?
Read every page, identify the notice or letter number, calendar the response date, compare the IRS statement with your records, and respond by the deadline if the notice asks for action or if you disagree.
Key insights
- The notice number and response date are the first facts to capture.
- A balance due notice is different from a final notice of intent to levy.
- If you disagree, the IRS usually expects a written response with supporting documents by the deadline.
How to read an IRS notice
Most IRS letters are about a specific tax account issue: balance due, refund change, identity verification, missing information, corrected return, or processing delay. The right response depends on the letter, not on a generic script.
Find the CP or LTR number, the tax period, the amount shown, the response date, and the instructions. Keep a copy of the entire notice because attachments and contact stubs often matter.
When a notice becomes urgent
Notices that mention levy, lien, hearing rights, default, garnishment, or a final deadline should be treated as time-sensitive. Missing a response window can make the next step harder, especially when appeal rights are involved.
What to include in an intake summary
You can describe the notice without exposing sensitive identifiers. Share the notice number, tax year, general balance range, deadline, and issue type. Do not put Social Security numbers or full account numbers in a basic web form.

Frequently asked questions
Where is the IRS notice number?
The IRS says the CP or LTR number is generally found on the right corner of the letter or notice.

Not always. Many notices explain the action needed. If you must call, use the phone number on the notice or an official IRS number.
What if I disagree with an IRS notice?
Follow the notice instructions, respond by the deadline, and include copies of documents that support your position.
