W-2 and WH-3 Electronic Filing FAQs

Can files contain more than one employer record (RE)?

For a single business, yes, a file can contain more than one RE record, but all RS records must contain the same TID number. The TID number is located at position 331 of the RS record. The TID number should be the same for every RS record in the file. Each WH-3 must only contain information for the company for which the file is being uploaded. Each business must have its own WH-3 for uploading.

Software vendors uploading through batch upload can upload files containing all clients in which a Federal Form 2848 is on file. Clients do not have to be registered in INtax.
