If anyone reading Usenet is affected, just a reminder of the new requirement that information returns must be filed with IRS electronically if 10 or more are being filed. This affects those of us engaged in trade that made reportable payments throughout tax year 2023.
1098-E, Form 1098-Q, Form 1098-T, the Form 1099 series, Form 3921, Form
3922, the Form 5498 series, Form 8027, and Form W-2G.
Helpfully, one must obtain a Transmitter Control Code, because gawd forbid we shouldn't need a another number. This takes up to 45 day. If one doesn't obtain the code now, then you may be filing late.
Corrected forms have their own threshold.
That threshold is a single return, if the original return was required to be filed electronically. According to comments received before the regulation was finalized, IRS did not yet have an adequate on line process for filing corrected information returns, but the regulations were finalized without it. I have no idea what's been set up for electronic filing of corrected returns in the last year.
