Did not get an identity pin this year but I have one from several years ago should I use that?

[Opus 17]

If you have a 6-digit IP PIN, it changes every year and the IRS mails you a new one in December.  If you lost it, you can call the IRS and ask them to mail a new one.  IP PINs are only issued to victims of identity theft.

All taxpayers need a 5-digit e-file PIN to confirm their identity.  This can either be the self-selected PIN you picked the first year you e-filed, or it can be your AGI from last year's tax return.  If you filed with Turbotax last year and start this year by importing your file, your AGI or 5 digit pin will carry over automatically.
