This work addresses the lack of harmony between the concept of permanent establishment (PE) in International Tax Law and the advent of the digital era. The fixity requirement can easily be avoided by enterprises that operate within the digital economy and benefit from its advantages.

This work examines the possible alternatives, paying special attention to significant digital and economic presence as a proposed taxable nexus.
