Navigating tax complexities in global expansion

3 April 2026

As organisations look to expand into new markets, international tax considerations are becoming an increasingly influential factor in strategic decision making. While global alignment around OECD principles has introduced greater consistency across jurisdictions, local tax, regulatory and reporting requirements continue to create significant complexity for businesses pursuing international growth.

Catherine Hall, Partner, Forvis Mazars in the UK, highlights that success depends on planning early and understanding how these complexities translate into real operational, infrastructure and governance demands. Building flexibility into tax and compliance models, supported by clear oversight and the right technology, is critical to navigating ongoing regulatory change. Increasingly, AI is helping organisations enhance efficiency, improve data quality and gain deeper insight across tax and finance functions, enabling faster, more informed decision‑making.
