Problem: The IRS - not eFile.com - rejected your tax return because the IP PIN - Identity Protection Personal Identification Number (IP PIN) - you entered for your dependent doesn't match IRS records.
Solution: Sign into your eFile.com account at https://mytaxes.efile.com/1040/SignIn/ and click on My Return and follow the instructions on the right side and correct this.
The Identity Protection PIN (IP PIN) is a PIN either assigned by the IRS or requested by the taxpayer, to victims of attempted identity theft, and the number is different from your prior-year AGI (to verify your identity with the IRS). The IP PIN is 6 digits, and it is sent to you in a letter from the IRS. Alternatively you can obtain your IP PIN online via the IRS website here:
If you cannot find your IP PIN, then you have to paper file, and it will unfortunately take longer to process your return.
Then re-eFile your federal and state returns at no additional charge.
