This article applies to Wave Payroll in the U.S.

In order to complete your Federal W2 filing with Social Security Administration, you will need to register with Social Security Business Services Online (SS BSO). Enrollment can be completed in minutes. After enrolling, you will just need to upload the Formatted Wage File that Wave provides. The SS BSO site can be found here.
