Do You Have Effectively Connected Income?

Answer a few questions to assess whether your LLC has ECI and what it means for your US tax obligations.

Step 1 of 6

Does your LLC have any employees or contractors working in the United States?

What is Effectively Connected Income (ECI)?

Effectively Connected Income (ECI) is income earned by a foreign person or entity that is connected to a US trade or business. When income qualifies as ECI, it is taxed on a net basis — meaning you can deduct expenses against it — at the same graduated rates that apply to US persons (up to 37% for individuals, 21% for corporations). ECI must be reported on Form 1040-NR (for individuals) or Form 1120-F (for corporations).

What is a US Trade or Business (USTB)?

A US Trade or Business exists when a foreign person or entity engages in activity within the United States that is "considerable, continuous, and regular." Common indicators include having US employees, maintaining a US office, performing services in the US, or selling inventory through US-based operations. Simply trading stocks through a US broker generally does not create a USTB (the "trading safe harbor"). The determination is facts and circumstances based — there is no bright-line test.
