June 10, 2021 MeF 7004 stakeholders: We are providing Tax Year 2021 Extensible Mark-up Language (XML) Schemas and Business Rules for the following forms that include new tax year form(s) and tax law changes. Included in the 2021v1.0 Schema package are "DIFF" files which identify the difference between the 2020v2.0 Schema package and the 2021v1.0 Schema package. The XML standardization was applied and are available for program purposes. The Schemas and Business Rules will be used in ATS or Production. Form 7004 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 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.
