Form 1120 Schemas and Business Rules Distribution is now through the Registered User Portal and your e-services mailbox. This mailbox is part of the Secure Object Repository (SOR). Users will access their mailbox in their existing e-services account to pick up the schema and business rules packages.

For the 1120 XML Schemas, the Instance Document contained in the schema files is viewable with any generic Multipurpose Internet Mail Extensions (MIME) reader. See the 1120 "Instance Document" for a sample of 1120 transmission.

Business Rules are posted in two different formats which contain identical information – Adobe (PDF) and a comma-separated file (CSV). A column within the file identifies changes made from the previous version.

If you have any questions about the Schemas or Business Rules, please send your inquiry to the MeF Mailbox.
