EY Global Tax Controversy Flash Newsletter (Issue 93) | Rethinking Tax Operations: Why co-sourcing is transforming compliance and controversy management

As tax complexity intensifies, organizations are facing a growing paradox — significant investment in compliance is not reducing the cost or frequency of tax controversy. In this article, Why managing tax compliance and tax controversy should be co-sourced, authored by EY Partners Luis Coronado and Steve Foster, we explore why leading tax functions are rethinking their operating models and turning to co-sourcing as a strategic solution. By integrating internal expertise with external, technology-enabled capabilities, co-sourcing helps enable better data quality, greater transparency, and a shift from reactive dispute management to proactive risk prevention. Discover how this approach is helping organizations improve outcomes, enhance efficiency, and create a more sustainable model for managing tax risk.
