Tax residency refers to the country that has the legal right to tax your income. It is one of the most important concepts in international taxation because residency determines whether you owe tax on worldwide income or only on income earned in a specific country.
In simple terms, being a tax resident means the country considers you a permanent or long-term inhabitant for tax purposes (even if you are not a citizen).
The United States bases tax residency on citizenship and presence tests rather than just physical residence. U.S. citizens and green card holders are automatically considered U.S. tax residents, regardless of where they live.
Non-citizens can become residents for tax purposes if they meet the Substantial Presence Test. It involves being physically present in the United States for at least 31 days in the current year and 183 days over three years (calculated with a specific weighted formula).
If you qualify as a resident alien, the U.S. taxes your worldwide income. Those who do not meet the test are generally treated as nonresident aliens, taxed only on U.S.-source income.
Israel takes a different approach. It focuses on your center of life. The Israeli Tax Authority looks at factors such as:
There is also a quantitative test: spending 183 days or more in Israel in a single tax year, or 425 days or more over three consecutive years (including at least 30 days in the current year), usually makes you a resident for Israeli tax purposes.
However, residency status in Israel is based on overall circumstances, not just the day count. Even if you don’t meet the threshold, other evidence can prove that you’re an Israeli tax resident.
Your tax residency determines:
If you are considered a resident in both countries under their domestic laws, the U.S.–Israel Tax Treaty provides “tie-breaker” rules to decide which country is your primary tax home. These rules consider where your permanent home is and where your personal and economic relations are closer.
Understanding these differences helps prevent costly mistakes such as being taxed twice on the same income or missing reporting requirements in one jurisdiction.
For Americans living in Israel, understanding tax residency is critical to managing cross-border compliance. You may be considered a tax resident in both countries, which makes it mandatory to report your income to both the IRS and the Israeli Tax Authority.
Coordinating your residency status, claiming available treaty relief, and ensuring accurate filing in both systems can prevent double taxation.
