Case Study: Sinclair Broadcast Group achieves faster, accurate multi-entity tax consolidation and automated compliance with CSC Corptax

Choosing a Single Solution over Separate Systems

Sinclair Broadcast Group, one of the largest and most diversified television broadcasting companies in the U.S., needed a modern, scalable income tax solution to manage 500 legal and disregarded entities and 173 station-level general ledgers. Facing slow, error-prone processes with their legacy Vertex system and concerns about Onesource, Sinclair evaluated alternatives and selected CSC Corptax (implementing Corptax Compliance and Corptax Office) to address inefficient data entry, manual overrides, lack of traceability, and burdensome consolidation.

CSC Corptax delivered a fast, streamlined implementation of Corptax Compliance and Corptax Office, providing a single system of record with automated Excel dataflows, easy drill-down to source ledgers, and rapid recalculation. The result: consolidation and recalculations that once took hours now take minutes, automated import/export reduced manual work and errors, confidence in every calculation improved, and staff gained time for review, analytics and planning—with Sinclair noting materially faster consolidation versus Vertex and Onesource.
