WTax and Ultimus Partner to Deliver Global Withholding Tax Relief to US Investors

Ultimus integrates WTax as its default solution for foreign withholding tax relief documentation, management, and reclaim services.

January 14, 2026 – WTax, the leading provider of cross-border withholding tax solutions, has expanded its partnership with Ultimus Fund Solutions (Ultimus), a premier independent provider of comprehensive fund administration, middle office, accounting, and investor services.

Building on a successful collaboration that began in May 2024, WTax now serves as Ultimus’ dedicated solution for all foreign tax relief at source document completion, ongoing management, and reclaim services. This enhanced partnership is designed to simplify and accelerate complex international tax processes for Ultimus’ fund administration and investment management clients globally, resulting in improved filing efficiency and optimized recovery rates.

“We’re excited to deepen our partnership with Ultimus,” said Liam Ilić, Director and Global Head of Partnerships at WTax. “Withholding tax recovery is a complicated and often overlooked way of generating investment alpha, which can be constrained by complex filing requirements and fragmented reclaim processes.

By simplifying and centralizing the management of withholding tax, we are helping Ultimus’ clients unlock all available relief and recoveries. Ultimus’ dedication to excellence in investment operations and its drive for innovation perfectly complement WTax’s commitment to providing leading cross-border tax recovery services.”

Through this strategic partnership, Ultimus’ clients will gain access to WTax’s proprietary tax technology and the expertise of over 250 specialists globally, all working to optimize their tax relief and reclaim entitlements, simplify documentation and filing procedures, and ultimately elevate fund performance.

Joel Lieb, Senior Vice President, Relationship Management at Ultimus, emphasized the value of the enhanced partnership, noting that WTax delivers a comprehensive, end-to-end withholding tax solution covering everything from relief-at-source processing to reclaim entitlement identification, powered by a sophisticated rule engine.

“Our clients benefit from expert guidance to achieve the optimal mix of relief-at-source and reclaim recoveries, along with access to a live reporting portal, customizable reporting, and support with accruals and accounting,” he said. “This partnership enables us to offer a fully integrated tax recovery service to our growing client base.”
