U.S. Tax Considerations for Foreign Persons
Navigating Effectively Connected Income (ECI), FDAP withholding, tax treaties, Form 5472, and non-resident entity tax compliance for cross-border founders.
Cross-Border Legal & Tax Guidance for Non-Resident Founders
This comprehensive practice overview discusses the U.S. federal and state income tax consequences of the commercial activities of foreign persons and non-resident alien individuals engaged in a trade or business within the United States.
⚠️ Crucial IRS Compliance for 25%+ Foreign Shareholders
Non-resident alien founders operating US LLCs or Delaware C-Corps must maintain strict records of capital injections, founder loans, intercompany transfers, and vendor payments. Every cross-border transfer must be disclosed on IRS Form 5472 to avoid the statutory $25,000 penalty.
Core Topics Covered in Our Consultation:
- U.S. Trade or Business (ETBUS) Determination: Analyzing whether software development, dropshipping, SaaS, or consulting crosses the threshold of active US trade.
- Effectively Connected Income (ECI): Distinguishing revenue tied to US economic presence from purely foreign-sourced income.
- FDAP Withholding & Treaty Optimization: Structuring royalty, dividend, and service fees under applicable double-tax bilateral treaties to reduce 30% gross withholding.
- State-Level Corporate & Sales Tax Nexus: Identifying physical and economic nexus in states like California, Texas, and New York.

Frequently Asked Questions
What triggers US tax obligations for a foreign entrepreneur?+
A foreign person is subject to US federal taxation if they are engaged in a trade or business in the United States (ETBUS). Generally, this requires having dependent agents or physical activities/employees in the US. Purely selling digital software or services overseas without US personnel may not constitute ETBUS, but state sales tax or FDAP withholding may still apply.
Why is IRS Form 5472 so critical for non-US owners?+
IRS Section 6038A requires any 25% foreign-owned US Corporation or foreign-owned Single-Member LLC to file Form 5472 detailing reportable transactions with related foreign parties. Failing to file or filing an incomplete Form 5472 triggers an immediate, non-negotiable $25,000 penalty per instance per tax year.
What is the difference between FDAP and ECI income?+
FDAP (Fixed, Determinable, Annual, Periodical) consists of passive investment income such as dividends, royalties, and interest, typically taxed at a flat 30% gross rate (or lower treaty rate) via withholding. ECI (Effectively Connected Income) is active trade or business income taxed at standard US graduated rates after allowable business expense deductions.
