If your federal return is rejected with IRS Reject Code IND-664, IND-665, IND-666, or IND-667, then the primary or secondary taxpayer's social security number appears more than once in the IRS files for the prior tax year. Therefore, they are unable to match the information and will not allow you to use the self-select PIN method to e-file the return. The IRS requires that you print and mail in your federal return.
If you have questions regarding this rejection, they may be directed to the IRS at 1-800-829-1040.
