Understanding your CP515 notice

What this notice is about

This notice is a reminder that we have no record that you filed your prior tax returns. We have reason to believe you need to file a return.


What you need to do

  • Respond to the notice by:
  • Filing your tax return immediately with the completed Form 15103, Form 1040 Return Delinquency PDF to explain:
    • Why you are filing late; or
    • That you’ve already filed.
  • We accept returns electronically for the 2 most recent prior years. However, you must locate an e-file provider who offers this service.
  • Completing Form 15103, Form 1040 Return Delinquency PDF, to explain:
    • Why you don’t have to file.
  • Return the completed Form 15103 and tax return, if applicable to the address on your notice. You can fax it to the fax number in the notice using either a fax machine or online fax service.
