Social security business services online (SS BSO) registration guide

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

In order to complete your Federal W2 filing with Social Security, you will need to register with Social Security Business Services Online (SS BSO). Enrolment 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.

You must register in order to use BSO. You do not need to re-register every year; however you will be prompted to change your password if you login after 90 days.

Every BSO user must register personally. You may not register on behalf of another person. Even if you are working on behalf of a client, register as yourself.

In order to complete registration quickly and easily, please have the following information available:

  • Name as it appears on your Social Security card,
  • Social Security Number,
  • Date of birth,
  • Home mailing address,
  • Telephone number,
  • Fax number (optional), and
  • Email address.

To register, go to: www.socialsecurity.gov/bso/bsowelcome.htm. Choose Register at the right hand side of the page, and complete the following steps.

  1. Select the I Accept button to indicate that you have read and understand the user certification statement and agree to its contents. This will open the registration form.
