I know the PIN rigmarole is not perpetual, but I couldn't find anything that shows how many years a taxpayer will suffer from it.  I thought I saw somewhere it ends for a victim after five years.  The IRS obviously isn't too concerned about identity theft, because they are a couple years behind on processing Form 14039.  And mailing refund checks is so hazardous they won't do it anymore -- but PIN's are only delivered by mail?

If you don't want to use the "two-year comparison" feature to remind yourself that there was Social Security income last year, how do you check on whether a 1099-R was received from each regular payer? I'm not quite ready to notify my clients, "don't rely on me because all I do is rely on artificial intelligence."
