Navigating the world of cross-border taxation can feel like trying to decipher ancient Greek—unless you have the right guide. The Greece U.S. tax treaty, officially known as the United States–Greece Income Tax Treaty, is a long-standing agreement designed to help individuals and businesses avoid the headache of double taxation while encouraging investment and economic cooperation between the two countries. Signed in 1950 and still relevant today, this treaty covers key areas such as residency rules, withholding tax rates, business profits, dividends, interest, royalties, and even the taxation of students and professors. For Americans living in Greece or Greeks earning income in the U.S., understanding the treaty’s provisions—especially the foreign tax credit, the savings clause, and permanent establishment rules—can mean the difference between a smooth tax season and a tangled mess.
What Is the Greece U.S. Tax Treaty?
The Greece U.S. tax treaty is a bilateral agreement between the United States and Greece that aims to prevent double taxation—where the same income is taxed by both countries—and to clarify which country has the right to tax specific types of income. The treaty applies to both individuals and businesses, offering rules for determining tax residency, defining what constitutes taxable income, and setting reduced withholding rates on certain payments like dividends and interest.

Key Benefits and Provisions
Double Taxation Relief
The primary goal of the treaty is to prevent double taxation. This means that if you pay taxes on your income in one country, you can usually claim a credit for those taxes in the other country. For example, a U.S. citizen living in Greece who pays Greek income tax can claim a foreign tax credit on their U.S. tax return, reducing or even eliminating their U.S. tax liability.
Foreign Tax Credit
The foreign tax credit is one of the most important tools for expats. It allows you to offset taxes paid in Greece against your U.S. tax bill. In many cases, especially since Greece’s tax rates are often higher than the U.S., this can result in owing little or no U.S. tax on your Greek income.
Savings Clause
There’s a catch: the treaty includes a “savings clause” that preserves the U.S. government’s right to tax its citizens as if the treaty didn’t exist. This means most treaty benefits—like exemptions for certain types of income—don’t apply to U.S. citizens. However, the foreign tax credit is still available, which is why it’s so crucial for Americans abroad.
Residency and Permanent Establishment
The treaty defines residency rules to avoid confusion over where you should pay taxes. It also clarifies what constitutes a “permanent establishment,” which determines whether a business is subject to tax in the other country. If you don’t have a permanent establishment, your business profits may only be taxed in your home country.
Withholding Taxes
The treaty reduces withholding tax rates on dividends, interest, and royalties. For example, interest payments from Greece to U.S. residents are generally exempt from Greek tax if the interest rate doesn’t exceed 9% per year. Dividends and royalties may also benefit from reduced rates, but the rules can be complex.
Exchange of Information
Both countries agree to share tax-related information to prevent tax evasion and ensure compliance. This cooperation helps keep things fair and transparent for everyone involved.
Special Provisions for Individuals
Students and Professors
If you’re a student or professor temporarily working or studying in the other country, the treaty offers special exemptions or reduced tax rates, making it easier to pursue education or research abroad.
Pensions and Social Security
Pensions are generally taxed in the country where the recipient lives. The U.S. and Greece also have a separate totalization agreement to prevent double taxation of Social Security benefits, so you won’t have to pay Social Security taxes to both countries for the same work.

Compliance and Reporting
Filing Requirements
