ECS has won a two-year contract valued at $26 million in support of the Services and Enforcement Division of the Internal Revenue Service (IRS). The IRS is currently engaged in modernization efforts as part of the agency's six-year IRS Modernization Plan released in 2019. Key pillars of the plan include improving the taxpayer experience and core taxpayer services and enforcement, modernizing IRS operations, and standardizing cybersecurity and data protection.

ECS will be leading the largest data migration in IRS history by migrating current applications, business workflows, and forms to SharePoint Online, a collaboration and document management platform that integrates natively with Microsoft Office. For legacy applications, workflows, or forms that cannot be directly migrated to SharePoint Online, ECS will redesign those applications on Power Platform, a modern low-code platform.
