Employer W-2 Filing Instructions & Information

Alert

The Social Security username sign-in option is no longer available. You must sign in with either a Login.gov or ID.me account to gain access to employer services.

Alert

We would like feedback on a new application that will allow an employer (Responsible Entity Officer (REO)) to delegate and authorize who can submit wage reports for their company via Business Services Online (BSO). This new process will allow an REO to fully manage access for their users.

We are looking for volunteers for a study we are conducting during the week of September 8^th to participate, you must qualify as an REO for the entity you are registering for.

For more information including how to participate, please visit the REO Volunteers page.

Register to Use Business Services Online

You must register to use Business Services Online – Social Security’s suite of services that allows you to file W-2/W-2Cs online and verify your employees’ names and Social Security numbers against our records.

Your BSO user ID and password can no longer be used to access employer services. You must sign in with your Login.gov or ID.me account to gain access to employer services.

If you already have a Login.gov or ID.me account, do not create a new one. You can use your existing account to access employer services. Start at the BSO Welcome Page, then select “Sign in” or "Create account" in the "Employers" section.
