Haven't received our PIN yet. Normally we would have received it by now.
We had a fraudulent return filed several years ago in 2014 using my SS#. For that year, we had to file by paper and it took nearly two years to get our refund. At the time, I seem to recall some communication from the IRS stating that, for the next 3 years, we would be sent a PIN by mail in Dec/Jan, which would be required to e-file. We got the PIN each of the last 3 years, usually in very early Jan. That would have been 2015, 2016, and 2017. So unless something changed, I guess 2018 is the year we go back to e-filing with no PIN. I was sort-of hoping they would continue to send PINs anyway... and maybe it's just delayed by the shutdown. If not, maybe I'll look into "opting in" if I still can.
Obviously, my SS# is floating around the dark web. Not sure why the IRS would assume it's no longer a problem after 3 years. If no PIN is required, there will probably be another fraudulent return filed early this year.
