Helping clients meet their business challenges begins with an in-depth understanding of the industries in which they work. That’s why KPMG LLP established its industry-driven structure. In fact, KPMG LLP was the first of the Big Four firms to organize itself along the same industry lines as clients.

ONESOURCE Enterprise Cloud migrations

Learn how KPMG helps enterprises prepare, plan, and execute a successful migration of ONESOURCE Determination Original.

Thomson Reuters has announced the strategic decision to discontinue investment in the maintenance and support of ONESOURCE Determination Original and focus our resources on developing and enhancing ONESOURCE Determination Enterprise. Support for ONESOURCE Determination Original will officially end on June 30th, 2026.

Keeping your ONESOURCE environments in line with the supported ONESOURCE release path is critical to your business. Customers who are not migrated to ONESOURCE Enterprise Cloud will not receive the tax content updates, software support, or security patches needed for ONESOURCE to remain accurate and effective, which poses significant risks to your business.

Whether you are an On-Premise or Original Cloud customer, the ability to properly calculate and report taxes is critical to your organization and is dependent on successful migration execution and validation.

KPMG has the right experience and toolkits to help your organization through this process to help ensure that your core purchasing and billing processes do not experience negative impacts related to the migration and any enhancements made deliver positive changes to your organization.
