# I Will Advise Foreign Owners of a US Single-Member LLC on Tax

Running a US single-member LLC as a foreign owner is one of the most misunderstood tax situations in international business. Get it wrong and you face fines starting at $10,000 — rising to $25,000 per LLC. Get it right and you operate with clarity, confidence, and full compliance.

This consultation is designed specifically for non-resident foreign individuals who own a US single-member LLC and need to understand exactly where they stand with the IRS. Whether you are based in London or anywhere else outside the United States, this service cuts through the complexity and gives you actionable, plain-English guidance.

\*\*What We Cover\*\*

A foreign-owned single-member LLC that has not elected to be treated as a C corporation is automatically classified as a disregarded entity. That classification has significant implications. Your LLC does not pay US income tax unless it generates income that is effectively connected to a US trade or business, or income that qualifies as FDAP — Fixed, Determinable, Annual, or Periodical income.

During the consultation we will walk through your specific situation, covering:

— Whether your LLC’s income is subject to US taxation based on the nature of your business activities (personal services such as marketing, IT consultancy, web development, online teaching, and tech support are typically treated very differently from product sales into US markets)
 — Your mandatory filing obligations, including informational forms such as Forms 1120 and 5472, which must be submitted on time regardless of taxable income
 — FDAP income rules and the exclusions that may apply to your situation
 — The fines and penalties associated with non-compliance and how to avoid them
 — Any additional tax obligations that arise if your LLC sells physical or digital products into the US market

\*\*Who This Is For\*\*

This service is ideal for foreign nationals — including those based in the UK and Spanish-speaking countries — who have already formed a US LLC or are preparing to do so, and need clear professional guidance on their US tax position. It is equally valuable for expats living in the US who hold or plan to hold a single-member LLC structure.

\*\*How It Works\*\*

Once you place your order, share your details via the order chat. We will review your situation ahead of the session so your consultation time is focused and productive. The entry-level session is a 45-minute live consultation with up to five hours of preparatory and supporting work included. Larger tiers extend the scope to cover more complex situations with additional review work and revision rounds.

Spanish-language consultations are available — please mention this when placing your order.
