Why am I getting a bill from my original return when I filed an amended return showing I do not owe?

You may receive a bill for one or more of the following reasons:

• Your amended return has not completed processing
• We did not receive a response to our letter
• A credit claimed on your amended return was adjusted or disallowed
• Your amended return was disallowed
• Your amended return was adjusted:
  • The amount claimed as previously paid was corrected to agree with our records
  • The amount claimed as your previous refund and/or credit forward was corrected to agree with our records
  • The amount claimed as previously paid included nonrefundable penalty and/or interest
