Operational income refers to earnings generated from active business operations connected to a trade or business in the United States. This typically includes profits from running a business within the U.S.
For example, a foreigner owning a restaurant in New York would have their earnings from this business classified as operational income activity because the business operations are actively conducted within the US.
When foreign individuals engage in operational income activities, they generate what is known as effectively connected income (ECI). ECI refers to income that arises from a U.S. trade or business. This income is generally subject to graduated tax rates for foreign individuals.
In contrast, foreign corporations face corporate tax rates on their ECI, like those that apply to U.S. citizens and residents. It’s important to note that a reduced tax rate may be available for individuals and entities under applicable tax treaties.
For example, Sarah, a German citizen and non-U.S. resident, owns a restaurant in Chicago while living in Germany. She earns $200,000 annually from her restaurant operations in the U.S. This $200,000 in income is considered ECI because it is actively earned through a business in the U.S.
