Who we are
Tax expertise, built for a data-driven world
Tax Data Analytics (taxData) is a Luxembourg-based firm that supports professional service providers and portfolio owners in the design and implementation of data-driven tax systems. We deliver solutions tailored to your systems, workflows, and regulatory environment.
Our work bridges international tax, data engineering, and real-world operational experience in Luxembourg. Whether your data sits in complex systems, spreadsheets, or both, we start from your current setup and build practical, scalable solutions from there.

The team
Built and delivered by a specialist
You work directly with the founder from first call to final deliverable.
Ruben brings 25 years of professional experience, including over two decades in international tax and transfer pricing: 14 years at PwC across four jurisdictions, followed by corporate counsel and advisory roles in Luxembourg, where he served as director of more than 50 holding and financing vehicles.
His tax background is paired with an academic degree in computer science with a focus on machine learning and artificial intelligence. That foundation allows him to design and build data solutions directly from tax technical requirements, rather than translating them through intermediaries.
