Understanding your CP87B notice

What this notice is about

You claimed yourself, but someone else claimed you as a dependent for the same tax year on another tax return.

You can’t claim yourself if someone else is entitled to claim you as his or her dependent.


What you need to do

Review the rules for claiming each dependent or qualifying child in Publication 501, Dependents, Standard Deduction, and Filing Information PDF.
After reviewing the rules:

  • If you don’t qualify as someone's dependent, you don’t need to contact us or take any action.
  • If you qualify as someone's dependent, you must correct your tax return by filing a Form 1040-X, Amended U.S. Individual Income Tax Return. The instructions for this form will guide you through the steps to correct your return. Mail your amended return to the IRS service center shown in the instructions.
