ERO, ERO Pin, and SS Pin

[John A]

Question from a newbie to the program:

On the "efile" tab in Preparer Manager, there's a checkbox for "ERO", and then input boxes for "ERO Pin" and "SS Pin".

If I'm using ATX to efile 1040s, and I have my IRS EFIN entered in the "EFIN" input box, should I just check the "ERO" box and enter my 5-digit ERO Pin?

(What, then, is the "SS Pin" for??)

Thanks!

Your SS PIN is if you are set up to E-file W-2s with the SSA. Yes, you put your ERO PIN in.
