Yes, you can use our W2 Mate software to import your data from an Excel spreadsheet and then create a W2 electronic filing submission in the EFW2 format ready for upload to the SSA BSO website. We can provide you with a template spreadsheet for W2s and the definition of each of the fields. You can send an email to firstname.lastname@example.org to receive the template.
