ECI Risk Threshold Screener

Effectively Connected Income (ECI) forces foreign investors to file U.S. tax returns and pay taxes at graduated rates. Use this screener to gauge whether a planned activity crosses the threshold into a "U.S. Trade or Business."

Legal Disclaimer

This is a simplified screener. ECI determination is highly fact-intensive. A foreign person who is a partner in a partnership that is engaged in a U.S. trade or business is themselves considered to be engaged in that trade or business. Always interpose a Blocker Corporation if ECI risk is present.
