@justme7071 - once you request and are issued a PIN, you MUST enter that PIN to be able to efile -
Since the IRS knows that certain SS#s are associated with that specific PIN, it will not accept an efiled return unless the PIN is used. And presumably, you are the only one who knows the PIN so only you can efile.
that will force someone trying to claim your dependents to paper file. THe IRS will scrutinize those returns very closely because they know the dependent SS#s are associated with a PIN and the PIN was not used on the paper return (because only you know it)
a new PIN is issued each year as additional security protection.
give it a try!
