I’m René van Gassen, part of Deloitte’s Tax Technology Consulting (TTC) team. Over my career, I’ve audited the (consolidated) tax positions of large multinationals and supported major Dutch companies in transforming their tax accounting and reporting processes.
Tax accounting is already a niche field, and optimizing these processes is even more specialized. Tax departments often struggle during closing periods due to overreliance on spreadsheets, outdated technology, and poor integration between tax and finance systems—challenges amplified by recent Pillar II developments. That’s where we come in!
My team and I help tax departments design, select, and implement effective tax reporting solutions for global and local needs. We bridge the gap between Finance, Tax, and IT, leveraging my expertise in tax accounting and experience implementing processes powered by tools ranging from MS Excel to enterprise performance management solutions.
In recent years, I’ve collaborated closely with software providers like Longview Tax, Thomson Reuters OTP, CCH Global Integrator, Vertex, and Oracle (HTP and TRCS). Notably, we’ve served as Oracle’s lead design advisors for HTP and TRCS development.
Building connections between traditionally siloed departments is my passion, and I’m dedicated to helping tax teams excel in an increasingly complex landscape.
