IRS CP Notices Decoded — What Each Number Means

Every IRS letter has a CP or LT code. The number tells you exactly what stage of collection you're in.

IRS computer-generated notices follow a standardized numbering system. The 'CP' prefix means Computer Paragraph; 'LT' means Letter. The number after tells you what the notice is for and how long you have to respond.
