KPMG Celebrates Market-Leading Alliance Between Thomson Reuters ONESOURCE and the Firm’s Comprehensive Tax Technology Services 

Big 4 firm recognized as Diamond Tier status for Thomson Reuters ONESOURCE Certified Implementer Program

DALLAS, Texas, October 21, 2019 – KPMG LLP and Thomson Reuters today announced another milestone in the market-leading alliance between Thomson Reuters tax technology and KPMG’s own innovative array of technology solutions for tax departments, with the designation of KPMG as Diamond Tier status for Thomson Reuters ONESOURCE Certified Implementer Program (CIP).

ONESOURCE is a valued component in KPMG’s successful drive to transform tax technology innovation and help corporations of all sizes and industries reimagine their evolving global tax compliance needs and unlock value for their organizations.

ONESOURCE tax technology solutions help streamline data and automate processes, helping companies boost collaboration within and outside their organizations to help achieve seamless tax compliance regardless of geographic location. The experience of KPMG’s teams in working with clients to use ONESOURCE in tandem with KPMG’s own technology solutions developed in KPMG Ignition consistently helps clients shape and reimagine the data-driven transformation of their tax departments.

“We’re incredibly proud of our work and long-standing relationship with Thomson Reuters. It’s a prime example of the investment KPMG is making to help our clients succeed as they reimagine their tax departments,” said Jeffrey C. LeSage, Americas Vice Chairman-Tax at KPMG. “We’re confident that our market-leading intelligent automation tools, data and analytics resources, and our staff at Ignition, along with ONESOURCE, will all help our clients successfully continue their transformation journey.”

“Our customers are seeking new ways to stay competitive in today’s changing business environment. They are moving to the cloud, developing new data analysis capabilities and deploying AI solutions and want innovative technology solutions to meet their tax needs,” said Piotr Marczewski, president of Thomson Reuters Corporates Customer Segment. “Together, KPMG and Thomson Reuters are leveraging the latest technology to develop tax solutions that address complex business issues and help our customers save time and money.”

KPMG has been part of the Thomson Reuters ONESOURCE Certified Implementer Program since 2010 and provides a complete set of services and technology to help customers in the areas of Direct Tax, Indirect Tax, Global Trade Management and Statutory Reporting.

In 2017, Thomson Reuters recognized KPMG with its Taxologist of the Year – Certified Implementer award for the “best use of technology to enhance tax functions.”

ONESOURCE has an industry-leading portfolio of global tax and accounting solutions for corporations that enables the streamlining of data and process automation across tax, accounting and finance functions. Today, it enables tax compliance and reporting in more than 180 countries.

Thomson Reuters introduced a tiered structure to its CIP in early 2018 to formalize the growing implementer ecosystem of Thomson Reuters ONESOURCE. CIP firms that have earned Diamond Tier status are certified across the entire ONESOURCE suite of applications, lead the highest volume of ONESOURCE implementations and have a global presence with certified implementers in a minimum of five countries. All CIP firms meet the same high-quality standards required to participate in the program. The tiers in the Thomson Reuters ONESOURCE Certified Implementer Program reflect the volume and scale of ONESOURCE implementation activity.
