Answers to Common Questions


When we send a notice from an account where we assessed penalties or interest, we include explanations for those assessments at the end of the notice. We assign a two-digit code to each of these explanations.

Which explanations are on your notice?

The tear-off stub on the last page of the notice lists the penalty codes assigned to the notice in the format aabbccddeeffgghh where aa is the first code assigned, bb is the second, and so on. If more than eight explanations print on the notice, only the codes for the first eight print on the stub.

Example: The 030919 printed above "INTERNAL REVENUE SERVICE" on the stub below means that penalty codes 03, 09, and 19 were assigned to the tax return for which this notice generated.
