What's New?

08/04/08 - The AccuWage 2008 software is now available to download.  The Troubleshooting page contains guidance to help you through downloading problems. The Help Guide contains extensive information on viewing, testing, and correcting errors in the wage report file.  Windows Vista users can now access the Help Guide from within the AccuWage software and/or download it from the Quick Links section.

Note: Beginning with AccuWage 2007, we no longer provide support for any AccuWage software downloaded to Windows NT or ME Operating Systems.

What is AccuWage/AccuW2C?

AccuWage/AccuW2C is free software from Social Security.

  • AccuWage is for use with Electronic Filing W-2 - EFW2 (formerly MMREF-1.)
  • AccuW2C is for use with Electronic Filing W-2c - EFW2C (formerly MMREF-2.)

The software allows you to check W-2 (Wage and Tax Statement) and W-2c (Corrected Wage and Tax Statement) reports for correctness before you send them to Social Security.

How does AccuWage/AccuW2C work?

First, you need to download and install AccuWage/AccuW2C software on your PC. Then, specify the directory where your W2REPORT or W2CREPORT file is located. AccuWage/AccuW2C reads the file and informs you of any errors it detects.

Software Policy

The AccuWage/AccuW2C software identifies most of the common format errors in wage submissions. Using this software greatly reduces submission rejections. Please be aware that even if no errors are identified by AccuWage/AccuW2C, your submission could be returned because of other errors.
