1099 correction process for multiple years
We have a supplier that has both a wrong TIN and primary address. We need to fix those and send corrected 1099s for the years 2019, 2020, and 2021.
I found Doc ID 637632.1 and read through the instructions. Do we need an effective dated row in each year to be able to run corrected 1099s for multiple years? Are there other special steps we would need to take to do this process effectively?
