The Form 1040 2011v1.0 schema and business rule packages have been posted to IRS.gov.
These schemas and business rules will not be implemented in the MeF ATS or Production environments. We are continuing to make updates to the schemas and business rules for Tax Year 2011 changes.
The "Diff" Files for 1040 are a comparison of the schema packages that are in Production for TY2010 to the TY2011 packages. Since we posted the developmental TY2010 schema packages we want to be clear that the Diff files are not a comparison of those schemas.
The Form 1040 2011v1.0 business rules have been posted in two (2) formats that contain identical information: Adobe (.pdf) and Comma Separated Values (.csv).
If you have any questions about the schemas or business rules, please send your inquiry to the Mailbox.
