Contribution File Requirements

In order for Slavic401k to service your retirement plan efficiently and facilitate the compliance testing and reporting, please supply us with only ONE file for each contribution with the following electronic information.

  • The file should be comma delimited with text fields in quotes, or an Excel spreadsheet.
  • A test file and employer ID list must be sent to Slavic401k prior to submitting your first deferral.
  • The file should include all companies who have adopted a 401(k) plan with complete census, whether or not the employee is eligible or participating.
  • Deferral, match, loan payment, profit sharing, and IRA should NEVER be negative.
  • All dates should have 4-digit years.
  • Any deviations from the standard format, or changes to employer ID code, must be approved by slavic401k.com.
  • If your plan is safe harbor, the contribution needs to be in the proper column. If it is a 3% profit share, it must go in the profit share column. If it is a 4% match, it must go in the match column.
