Case study

Attracting and retaining clients is an ongoing goal for the banking and financial services industry. Providing clients with unique, value-added services is a key element of this pursuit. And it’s exactly what led UMB to switch to ONESOURCE Trust Tax for its fiduciary tax services.

UMB was already outsourcing its fiduciary tax function to a large accounting firm, but it wasn’t realizing the benefits and cost savings that were expected.

“When we made the decision to outsource our trust tax function, we expected to eliminate much of the day-to-day involvement with fiduciary tax work. We just weren’t seeing the focus and attention from the provider we had desired. This is the core business of ONESOURCE Trust Tax, and we are now seeing the results we originally anticipated.” – Clyde Wendel, President, UMB Asset Management
