The 941x Quarterly Forms 2016v1.0 Schema and Business Rule package were posted on July 20, 2015 and an updated Business Rule package was posted on January 31, 2018 to IRS.gov. These Schemas and Business Rules were made available in the Assurance Testing System (ATS) on November 2, 2015 and on April 1, 2016 in the Production System. This Schema and Business Rule version is available for use in the ATS and Production System.
