Release Memo September 6, 2013

Exempt Organization Software Developers

We have posted updated XML Schemas and Business Rules for the EO forms to IRS.GOV for Tax Year 2013 (Processing Year 2014). 

Tax Year 2013 Schema Versions

  • Form 990 family (990, 990EZ, 990PF) -- Version 1.1
  • Form 1120-POL – Version 1.1

These changes will not be operational in ATS or Production. They will be superseded by additional changes prior to November 2013.

XML Schemas

The schemas are posted by form type and version number.  "Diff Files" are included that show the changes from the previous schema versions. 

Business Rules

Business Rules are posted, by form type and version number, in two different formats that contain identical information – Adobe (.pdf) and comma separated file (.csv). There are no changes to the business rules. The version numbers have been incremented to remain in sync with the schema.   

Key Changes


  • Form 990x (990, 990-EZ, 990PF) -- efileTypes.xsd, new estimate payment schema, and new shared dependency. 
  • Form 1120POL -- efileTypes.xsd and new shared dependency.

If you have any questions, please contact Tiwana Holland from the EO e-file team (202) 317-8778.
