What Is a Notice?

  1. A Computer Paragraph (CP) notice results from:

    • Input of notice codes

    • Computer analysis of an account on Master File (MF)

    • Posting of a transaction


  2. Internal notices/transcripts are issued to alert IRS employees of possible necessary action. Notices may:

    • Request payment

    • Give instructions

21.3.1.2.1  (10-01-2008)
Notice Types and Definitions

  1. Submission Processing Notices:

    • If a return is not processable due to missing information, Submission Processing sends the taxpayer a notice requesting the information. The Internal Revenue Restructuring and Reform Act of 1998 (RRA '98) requires the inclusion of telephone numbers on most notices. The phone number shown on these notices is the Toll-Free Customer Response line appropriate for the taxpayer's Business Operating Divisions (BODs).

    • These notices are pre-printed, some have boxes checked to indicate exactly what information is needed (a single copy is sent to the taxpayer). A return envelope is enclosed with the notice.

    • These returns have not completed processing and Integrated Data Retrieval System (IDRS) shows a dummy module with a Letter 12C , Individual Return Incomplete for Processing: Form 1949, Form 1040A and 1040EZ, or command code ERINV shows an ERS status code indicating a Letter 12C has been sent. Encourage the taxpayer to return the requested information in the envelope provided along with a copy of the notice. If the taxpayer returns the notice with the information, the return is treated as filed on the original received date.

  2. Settlement Notice—Informs the taxpayer of payment and interest due, math errors, and adjustments.

  3. Math Error Notice—Informs taxpayer of a math error found during processing and identifies the line on the return where the error occurred.

  4. Balance Due Notice—Requests payment, generates if a return does not have a math error and has a balance due. This is the first notice of balance due.

  5. Adjustment Notice—Informs taxpayer of adjustment made to the account by examination, adjustment, or taxpayer request. Generally the fourth and fifth digits of the Document Locator Number (DLN) of a Data Processing (DP) adjustment are 54. The fourth and fifth digits of the DLN of an Examination adjustment are 47.

  6. Offset Notice—Informs taxpayer of the offset of an available overpayment to an outstanding debit balance.

  7. Information Notice—Issued to provide information internally or to taxpayer. A response is not needed.

  8. Credit Transfer Notice—Informs taxpayer of a credit transfer when the CORR–DATE filed in FRM 34 is overlaid.

  9. IDRS Notice—Issued as a subsequent balance-due or return delinquency notice.
