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 solutions. We deliver solutions tailored to your systems, workflows, and regulatory environment.
Our work sits at the intersection of 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.

Implement
We extract, standardise, and integrate data across multiple sources, establishing a consistent and controlled data environment.

The team
Built and delivered by a specialist
You work directly with the founder from first call to final deliverable.
Ruben brings more than two decades of tax experience, including roles in tax structuring at PwC across multiple jurisdictions, followed by extensive advisory work in Luxembourg.
His expertise covers corporate taxation, transfer pricing, and cross-border structuring, complemented by formal training in computer science with a focus on machine learning and artificial intelligence. That background lets him design data solutions directly from the tax technical requirements, rather than briefing a separate team to build them.
