AMS customers have concerns about the Mailing addresses for the 1099 forms. Be assured that AMS is using the most current Mailing Address instructions for the 1099/1096 forms.
Currently in Version E-3.0 (or higher), in the 1099-etc software, we are using the addresses found in the 2020 Publication 1220,General Instructions for Certain Information Returns (Forms 1096, 1097, 1098, 1099, 3921, 3922, 5498, and W-2G). The posted Date for this Publication is 01/08/2021. You can find the Publication at https://www.irs.gov/pub/irs-pdf/i1099gi_20.pdf.
We are NOT using the 2021 Publication 1220, General Instructions for Certain Information Returns (Forms 1096, 1097, 1098, 1099, 3921, 3922, 5498, and W-2G), because this is for the 2021 1099 forms.
If mailing to the Austin address, we are now using the following:
Internal Revenue Service
