Foreign individuals and entities operating in or deriving income from the United States face a complex web of tax obligations. Effectively Connected Income (ECI) is taxed on a net basis at graduated rates, while Fixed, Determinable, Annual, or Periodical (FDAP) income, including dividends, interest, rents, and royalties, is subject to a flat 30% withholding rate unless reduced by an applicable tax treaty.

We ensure that every dollar of income is properly classified, every treaty benefit is claimed, and every filing obligation is met on time.

Answers
Get answers to the most common questions about our us inbound tax services services.
Effectively Connected Income (ECI) is income from an active US trade or business, taxed at graduated rates on a net basis after deductions. FDAP (Fixed, Determinable, Annual, Periodical) income, such as dividends, interest, rents, and royalties, is taxed at a flat 30% gross rate, withheld at source, unless a treaty applies.
Yes. Many US tax treaties reduce or eliminate the 30% statutory withholding rate on FDAP income. The specific rate depends on your country of residence and the type of income. We analyze every applicable treaty provision to ensure you receive the maximum benefit.
Form 5472 is required for any foreign-owned US corporation (25% or more foreign ownership) that has reportable transactions with related foreign parties. Failure to file carries a minimum $25,000 penalty per form, making timely and accurate filing critical.
Yes. Nonresident aliens generally need an Individual Taxpayer Identification Number (ITIN), and foreign corporations need an Employer Identification Number (EIN). We assist with all tax ID applications as part of our onboarding process.
Initial entity formation and EIN registration closes in 2 to 3 weeks. Full operational setup, including treaty analysis, banking, transfer pricing, and compliance calendar, typically takes 6 to 10 weeks. Timelines flex with immigration or investment deadlines.
