IRS Letter Check.

This tool explains the letter code. It does not diagnose your account.

Type the notice or letter code printed on an IRS notice or letter and get a plain-language explanation with links to official IRS sources.

A free tool from the Law Office of Alexander Powell, PLLC.

Type only the notice or letter code. Do not enter a name, Social Security number, or other personal details. The code is checked on your device and is not uploaded, stored, or sent by this site. No attorney reviews it. Nothing on this site is legal advice. Using it or contacting the firm does not create an attorney-client relationship by itself. The paper notice and current official IRS instructions control.

The code is printed on the notice, usually in a top or bottom corner. Examples: CP14, CP2000, LT11, Letter 3219.

Letters this tool covers

Each supported letter also has its own page in the IRS letter directory.

Sending the letter to this firm

If you want this firm to look at the letter, send the code and the date printed on it. Requesting a consultation does not make Mr. Powell your lawyer, provide legal advice, or protect a deadline. Representation begins only after a conflict check, after the firm agrees to the matter, and after both sides sign a written engagement agreement.
