1120x TY2014v4.0 Release Memo

October 27, 2014

MeF 1120/1120F/1120S Stakeholders:

We have posted Tax Year 2014 Production version eXtensible Mark-up Language (XML) Schemas and Business Rules for the following forms that include new tax year form(s) and tax law changes.  

The posted schema versions(s) 2014v4.0 were generated by using the latest schemas in production. The XML standardization was applied and are available for program planning purposes.  Included in the 2014v4.0 schema package are "DIFF" files which identify the difference between the 2014v3.0 and 2014v4.0 schema package.  

We have created a page to provide additional information relating to the XML standardization effort. This site includes the XML Workbooks and additional helpful items to assist in the transition process. For more information on the XML standardization effort see the Modernized e-File MeF XML Standardization page.
