First steps
Before you respond to any notice
Every IRS notice references a specific tax year and a specific issue, but it rarely shows your full account history. Before responding, it helps to confirm the balance or issue against your account transcript for that year — the notice is a snapshot, and the transcript is the complete, current record.
FAQ
Frequently asked questions
I got a notice that is not listed here. What should I do?+
Every IRS notice has a code printed in the top corner, usually starting with CP or LTR. An Initial IRS Review pulls your account transcript, which shows every notice issued on your account regardless of which specific one you received.
Does receiving a notice mean I am in immediate trouble?+
Not necessarily. Many notices, like a CP14, are routine first communications. Others, like a CP504, signal a more urgent situation. Reading your account transcript alongside the notice gives you the fuller context.
