At Montclare, we address the technical challenges of cross-border taxation resulting from global mobility and international asset allocation. Multiple tax jurisdictions create exposure to overlapping income, capital gains, and inheritance tax regimes — often without harmonized relief mechanisms.

Our role is to identify treaty access points, optimize corporate and personal tax positions, and ensure full compliance with EU and OECD frameworks, including DAC6, CRS, and ATAD.

We work with certified fiscal representatives and legal counsels to implement holding structures, foundation models (e.g. stichtingen), and hybrid vehicles where appropriate. All models are stress-tested against domestic anti-abuse rules, economic substance requirements, and exit taxation protocols.

Clients gain access to operational clarity, compliant structuring, and continuity in reporting — ensuring tax efficiency without compromising regulatory integrity.
