IRS Notice & Letter Response

An IRS letter has a 30-day clock. Ignoring it doesn't make it go away. We respond, include the right documents, and copy you on the entire response packet.

Most common notices we handle

We respond to notices across the full IRS collection and examination ladder:

  • CP2000 (underreporter inquiry)
  • CP14 (balance due)
  • CP501, CP503, CP504 (collection reminders and intent to levy)
  • LT11 / Letter 1058 (final notice before federal levy)
  • Letter 525 (30-day letter after examination)
  • Notice of Deficiency (90-day letter)
  • CP2501 (pre-CP2000)

What a notice actually means

Most notices are not audits. A CP2000 is a computer matching third-party documents against your return. A CP14 is a bill. The CP500 series is a collection escalation ladder. Each has a different correct response, and treating a bill like a dispute, or a dispute like a bill, wastes the response window doing the wrong thing well.

How we respond

Every response starts with your IRS transcripts, because the notice is a summary and the transcript is the record. We match the agency's numbers against the return, draft the response with documentation attached, send it certified, and calendar the follow-up. You get a copy of everything that goes out.

Have a specific situation?
Call the office and a human answers.

Response timeline

The response window varies by notice type. Most are 30 days. CDP (Collection Due Process) hearing requests under LT11 are strict 30 days from the notice date, not from when you open the envelope.

Common questions

The letter says I owe money. Do I have to pay before we can respond?
No. Responding on time and disputing or documenting the issue is the path, not paying first. Payment before examination stops the clock but doesn't foreclose dispute.
What if I already missed the deadline?
Call the office anyway. There are often remedies: audit reconsideration, amended return, CDP equivalent hearing, or collection appeal. The options narrow but don't disappear.
Is a notice the same as an audit?
No. Most notices are automated matching or collection letters. They still carry real deadlines, but the response is documentation and correspondence, not an examination.
