I'm guessing he is referring to EasyAcct's sister software the Information Return System, but I could be wrong. I don't use EasyAcct but I was under the impression that you filed directly with EasyAcct rather than converting to the other software. But I could be wrong about that too.
EasyACCT Information Return System( IRS) data file will create a W-2 file for the state and SSN. The 1099 contractor(vendor) file is submitted to the IRS.
However, it should be noted the IRS file is not compliant with the New Internal Revenue Service IRIS upload tool. But you can still upload the data file to the FIRE system.
