Global Minimum Tax for Multinational Corporations: Implications for Large Enterprises and Greece

This initiative, led by the OECD and adopted by the European Union, aims to combat base erosion and profit shifting (BEPS) practices that have long undermined national tax systems.

For many years, highly profitable multinational corporations have exploited regulatory gaps and mismatches across jurisdictions to artificially shift taxable profits to low-tax or no-tax jurisdictions. These practices have resulted in substantial erosion of national tax bases, with countries like Greece experiencing significant losses in public revenue.

Under the new regime, if a company pays less than 15% in taxes in any jurisdiction, other relevant jurisdictions—typically the country of headquarters—will have the right to impose a top-up tax to ensure the effective rate reaches the global minimum.

Who Is Affected?
The new minimum tax does not apply to small and medium-sized enterprises.
It targets multinational groups with annual consolidated revenues exceeding €750 million.

Greece's Position
Greece, in alignment with the EU directive, is proceeding with the phased integration of the new rules into its national tax framework.
This means that subsidiaries of large multinational groups operating in Greece will be required to comply with the new obligations.

Implications for Businesses
Multinational enterprises must now reassess their tax planning strategies. The traditional practice of strategically locating subsidiaries in low-tax jurisdictions is no longer as beneficial.
Instead, the emphasis is shifting toward tax transparency, compliance, and sustainable tax governance.

What Comes Next?
The success of the global minimum tax hinges on coordinated implementation and political commitment across jurisdictions.
The first step has been taken — and it is clear that the landscape of international taxation is undergoing a lasting transformation.
