Connection Information for Software Developers
This information is for developers of payroll and tax reporting software who
wish to enhance their products by incorporating the Internet business services
provided by SSA.
What is Business Services Online?
Business Services Online (BSO) is a suite of Internet services for businesses and employers
who exchange information with SSA. BSO users must complete a one-time registration process before using the system.
Connecting to BSO
Developers of payroll and tax reporting software can use SSA
processes to access the BSO and submit wage reports. The
BSO Welcome Page (
www.ssa.gov/bso/bsowelcome.htm) is the single point of entry for
all BSO users. Advise your customers that they will need Internet access and
a web browser
with 128-bit encryption and the ability to support cookies.
Developer Tips and Resources
- Provide a link to the Internal Revenue Service
(www.irs.gov) on the main menu
of your application. This allows users to obtain filing instructions, extension request
forms, and other publications.
- Provide processes for preparing wage-data files according to SSA's Specifications
for Filing Forms W-2 Electronically (EFW2) standards. The EFW2 format
is for original (Form W-2) files and the EFW2C format is for correction
(Form W-2c) files. Both the EFW2 and the EFW2C publications can be downloaded
- Incorporate into your application SSA's AccuWage software to check W-2 files
or AccuW2C software to check W-2c files. These software tools can be downloaded
- Automatically populate the User ID field in the RA/RCA record with the User
ID assigned to the person
who is attesting to the accuracy of the file.
- To enable SSA to send wage-data file resubmission notices
to the user's registration e-mail address, use 1 (Email/Internet) as the value
Preferred Method of Notification in the EFW2 RA/RCA record.
- Do not build submission files containing more than 1 million RW records or 50,000 RE records. If the employer
needs to submit more than 1 million Forms W-2, develop your application to break them into
smaller submission files.
If the organization files on behalf of multiple employers,
include no more than 500,000 RCW records or 25,000 RCE records per submission.
- Wage-data submissions must not span multiple files. Build each W-2 submission file
beginning with an RA record and ending with an RF record, and each W-2c submission file beginning with
an RCA record and ending with an RCF record.
- Provide a means to compress wage-data files before they are submitted to SSA. Compressing large data files can dramatically reduce transmission
time. Please use any compression tool that uses a standard "zip" file format. Compress each
wage-file separately to prevent the compression of multiple wage files into the same
- Establish an option or link to the BSO Welcome Page. This allows users to connect
to the BSO Welcome Page to submit the wage file. Once users log into BSO, instructions
are available for successful file submission.
