U.S. Tax Services for Founders, Executives, and Globally Mobile Employees

Generally, a non-resident alien living abroad does not owe U.S. individual income tax simply for holding shares in a U.S. C-Corporation. As long as the foreign founder does not physically perform work within the United States and the company does not distribute dividends, the founder has no individual U.S. tax liability or filing obligation with the IRS.

However, this exemption changes immediately if the U.S. entity is structured as a pass-through LLC or if the C-Corporation issues a formal dividend. In those cases, the income is considered Effectively Connected Income (ECI) or Fixed, Determinable, Annual, Periodical (FDAP) income, legally requiring the foreign founder to obtain an Individual Taxpayer Identification Number (ITIN) and file a Form 1040-NR non-resident tax return.

The United States utilizes a progressive federal tax bracket system for individual income, with top marginal federal rates reaching 37% for the highest earners in 2026. Unlike many European nations, the U.S. system is dual-layered, meaning individuals must file and pay taxes to the federal Internal Revenue Service (IRS) and separately to their specific state of residence.

Because state income taxes vary dramatically, an executive's exact tax liability is heavily dependent on their physical location in the U.S. For example, moving to California or New York exposes an individual to top state tax rates exceeding 10%, whereas establishing primary residency in states like Texas or Florida results in a 0% state income tax obligation.

The L-1A visa is strictly designed for intracompany transferees, allowing a European parent company to transfer an existing executive or manager to a U.S. subsidiary. The E-2 is an "investor visa" available exclusively to nationals of specific treaty countries (such as France or the UK) who are investing substantial personal or corporate capital into establishing a bona fide, operating U.S. business.

Choosing between these visas depends fundamentally on the company's operational history and the founder's immediate goals. While the E-2 allows for indefinite renewals as long as the U.S. business remains operational, the L-1A provides a more direct legal pathway to a permanent Green Card, which consequently triggers worldwide U.S. tax residency.

The IRS automatically classifies a foreign national as a U.S. tax resident if they meet the mathematical Substantial Presence Test (SPT), regardless of their immigration or visa status. To meet the SPT in 2026, an individual must be physically present in the United States for at least 31 days during the current year, and a weighted total of 183 days over the previous three-year period.

Once classified as a U.S. tax resident, the individual is legally required to report and pay taxes on their worldwide income to the IRS, exactly like a U.S. citizen. To avoid this, frequent cross-border travelers must carefully track their days and, if eligible, file Form 8840 (Closer Connection Exception) to prove their primary tax home remains in their European home country.

The Report of Foreign Bank and Financial Accounts (FBAR), officially known as FinCEN Form 114, is a mandatory annual disclosure for any U.S. tax resident whose combined foreign financial accounts exceed $10,000 at any point during the calendar year. This aggregate threshold includes foreign personal checking accounts, corporate accounts where the individual has signature authority, and foreign pension plans.

The U.S. Treasury Department aggressively enforces FBAR compliance to combat offshore tax evasion. Failing to file this form on time results in severe civil penalties starting at $10,000 per non-willful violation, while willful evasion can trigger penalties of up to $100,000 or 50% of the account balance, alongside potential criminal prosecution.

The Foreign Earned Income Exclusion (FEIE), claimed via IRS Form 2555, allows qualifying U.S. citizens and resident aliens living abroad to exclude a significant portion of their foreign-earned salary from U.S. federal income taxation. For the 2026 tax year, this inflation-adjusted exclusion limit allows expats to shield up to $130,000 of their earned income from the IRS.

It is critical to note that the FEIE only applies to active "earned" income, such as wages or consulting fees, and cannot be used to exclude passive income like dividends, capital gains, or rental profits. Furthermore, individuals must legally pass either the Physical Presence Test or the Bona Fide Residence Test to qualify for this tax exclusion.

Bilateral income tax treaties between the United States and European nations (such as the U.S.-France treaty) are explicitly designed to prevent the same income from being fully taxed by two different countries. These treaties accomplish this by establishing "tie-breaker" rules for dual residency, reducing standard withholding rates on cross-border dividends, and providing Foreign Tax Credits (FTC) that allow taxes paid in Europe to offset U.S. tax liabilities.

However, treaty benefits are never applied automatically by the IRS. To legally claim protection against double taxation, a foreign national or expat must formally disclose their treaty position by filing IRS Form 8833 alongside their annual U.S. tax return, detailing the exact treaty article that exempts their income.

Relocating from a high-tax jurisdiction like New York or California to a state with no individual income tax, such as Florida or Texas, provides an immediate and legal reduction in an individual's overall U.S. tax liability. Because state taxes are calculated entirely separately from federal IRS obligations, changing physical location is a primary tax planning strategy for wealthy founders and executives.

To legally claim the tax benefits of a new state, an individual must establish a genuine, provable "domicile" by severing economic and social ties to their former state. High-tax states frequently and aggressively audit high-net-worth individuals who claim to move for tax purposes but retain real estate, bank accounts, or business operations in their original location.
