CP2000 notices vary by specific situations. This means the IRS CP2000 program compares your tax return with information reported by third parties, such as employers, banks, and financial institutions.
When differences are identified, the notice will typically relate to one of several common categories:
- Income that was not reported or was reported differently
- Investment or trading activity
- Missing tax forms
- Filing status or dependent-related discrepancies
- Business or self-employment income issues
Each of these scenarios may require a different type of explanation or documentation.
