A modern tax treaty framework is essential to supporting business and investment between Greece and the USA.
This was the focus of the contribution by Stelios Papademetriou, Attorney at Law, Tax Advisor and Partner - Head of Tax at KPP Law, to the 22nd Athens Tax Forum, organised by the American-Hellenic Chamber of Commerce on 6 November 2026 in Athens.
The necessity to sign a new Double Taxation Treaty (DTT) between Greece and the USA is now imperative, as the current DTT, signed back in the 1950s, fails to respond efficiently to the realities of the modern global economy.
The rapid growth of digital commerce, new forms of corporate structures and the need for more effective exchange of information render the existing framework obsolete. Updating the treaty is expected to eliminate the existing tax anti-incentives and unintended double taxation arising from several clauses (e.g. permanent establishment, dividends, interest, royalties etc.), so as to enhance legal certainty for investors.
The ultimate goal is to align tax rules with contemporary cross-border business and investment activities, while boosting bilateral entrepreneurship between Greece and the USA.
