Would obtaining one of those PINS mean a fraudster could not fraudulent returns by snail mail? Like the IRS would then only accept e-file returns if they issue a PINS?
If you are assigned an IP PIN, no one can e-file a tax return in your name without it (including you). If you print and mail your return, there is a place next to the signature space where you write your IP PIN. If someone else files a printed, mailed return in your name without the IP PIN (or if you file by mail without it), the IRS will process the return, but it may take longer and the IRS may contact the filer asking that the filer provide additional proof of identity, either by mail or at an IRS office.
Failing to include an IP PIN on a printed return is not an absolute guarantee to stop fraudulent returns from being processed, but it should slow or stop many or most fraud attempts.
