• Current year business and schema rules

Form 1139 schemas and business rules are now distributed 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.

• Instructions for accessing the SOR mailbox

Business rules are posted in two formats that contain identical information for the MeF Form 1139 tax year 2025v1.0 business rules: Adobe (.pdf) and Comma Separated Values (.csv).
