1. What Does ETBUS (Engaged in Trade or Business) Mean?
Under Internal Revenue Code Section 864, a foreign individual or entity is subject to US federal income tax only if they are Engaged in a Trade or Business within the United States (ETBUS).
To be classified as ETBUS, you must have at least one dependent agent (employee or exclusive agent) operating physically within the US, or own physical real estate/warehouses in the US.
2. Effectively Connected Income (ECI) vs FDAP Income
Income generated from physical US operations or dependent US agents. Taxed at standard US progressive corporate/individual rates.
Fixed, Determinable, Annual, or Periodical income (dividends, interest, royalties from US sources). Taxed at 30% flat withholding tax (or lower treaty rate).
3. Why E-Commerce & SaaS Founders Qualify for 0% US Tax
If you manage a US LLC remotely from your home country (e.g. Pakistan, UAE, UK) to sell software, digital services, consulting, or e-commerce products:
- You perform all work outside the United States.
- You have no US physical office or employees.
- Your income is classified as foreign-sourced income under IRC Section 861.
