Case Study: Kiewit Corporation achieves automated tax provisions and 75% faster return-to-provision with CSC Corptax

Putting Tax and Accounting Teams on the Same Page

Kiewit Corporation, a Fortune 500 contractor, struggled with disconnected Accounting and Tax teams as they prepared 270 annual provisions across hundreds of entities. Reliance on Excel and manual processes meant months-long consolidations, repetitive 40-hour quarter rollovers, and a high risk of errors, so Kiewit selected CSC Corptax’s Single Solution to provide one user-friendly system for all stakeholders.

CSC Corptax deployed its Corptax Provision, Office, Data Exchange Manager and Pass‑Through modules to automate data imports, calculations, two‑way Excel flows and entity data management. As a result, one person can complete provisions for 50 corporations in one week; return‑to‑provision (RTP) analysis for 130+ legal entities dropped by 75% and uses half the staff; provision summaries and quarterly roll‑forwards are automated in seconds, 90% of return data is reused without manual work, and reconciliations and support have become far more reliable.
