Setting up a US company as a non-resident: LLC vs C-corp, and when it's the wrong move

Every year, thousands of entrepreneurs from the UAE, Europe and Asia set up a US entity to access dollar banking, raise American capital or simply invoice US clients without friction. The process is straightforward: no citizenship, no green card, no US address required. But the decision that matters is not whether you can form a company; it is whether you should, and which vehicle fits the structure you are actually building. Get the entity type wrong and you face a US$25,000 penalty for a single missed form. Get it right and the US entity slots cleanly into a multi-jurisdictional setup that serves you for years. This guide covers the real mechanics of setting up a US company as a foreign national in 2026, the LLC-versus-C-corp question, the filing traps most formation agents never mention, and the honest scenarios where a US entity is the wrong call entirely.

Can a non-resident own a US company?

Yes, fully. US federal law places no citizenship or residency requirement on company ownership. A non-resident individual or a foreign holding company can wholly own a US LLC or a US C-corp. You do not need a Social Security Number, a US visa or a US mailing address to register a company in the USA as a foreigner. What you do need is a registered agent in the state of formation and, shortly after incorporation, an Employer Identification Number (EIN) from the IRS. The ownership right is absolute, but it comes packaged with filing obligations that differ sharply depending on the entity type you choose. Those obligations are where most non-residents get into trouble.

LLC or C-corp: the real difference for a non-resident

The choice between a US LLC and a C-corp is not about prestige; it is about tax treatment, investor expectations and ongoing compliance cost.

• A C-corp is a separate taxpayer. It pays 21 per cent federal corporate tax on its profits. When those profits are distributed as dividends to a foreign owner, the US withholds 30 per cent (or a lower rate if a tax treaty applies between the US and your country of residence). A Delaware C-corp is the standard vehicle for raising US venture capital because VCs invest through funds that cannot hold pass-through entities.
• A single-member LLC owned by a foreign individual is, by default, a "disregarded entity" for US federal tax purposes. It does not pay US corporate tax. A multi-member LLC defaults to partnership treatment and files Form 1065.
• A Wyoming or New Mexico LLC is typically the lighter, cheaper option for a services business, a holding structure or an e-commerce operation with no US-based staff. Wyoming charges no state income tax; New Mexico charges no annual report fee for LLCs.
• A Delaware LLC carries a flat US$300 annual franchise tax regardless of revenue, plus registered-agent fees.

If you are not raising institutional US capital, the LLC is almost always the more efficient vehicle for a non-resident. If you are fundraising from US VCs, the C-corp is not optional: it is expected.

The single-member LLC and the filing catch

Here is the trap that cheap formation services routinely omit. A foreign-owned single-member US LLC must file Form 5472 attached to a pro-forma Form 1120 with the IRS every year. This is an information return, not a tax return: no tax may be due at all. But the penalty for failing to file is US$25,000 per form, per year. The IRS is not flexible on this.

Form 5472 reports "reportable transactions" between the LLC and its foreign owner. That includes capital contributions, loans, management fees and even rent paid between related parties. If you formed your LLC in 2025 and contributed US$10,000 in capital, that contribution is a reportable transaction. Many non-residents discover this obligation only after receiving an IRS notice, by which point the penalty has already been assessed.

The takeaway is blunt: if you are going to form a US LLC as a foreign owner, budget for a US CPA who understands foreign-owned disregarded entities from day one.

When a US company actually gets taxed: ETBUS and ECI

A US entity owned by a non-resident does not automatically owe US federal income tax. Two conditions must both be present: the business must be "engaged in a US trade or business" (ETBUS) and it must have "effectively connected income" (ECI). Running a consulting or SaaS business entirely from Dubai, with no US office, no US employees, no US warehouse and no dependent agent in the US, generally falls outside ETBUS.

That said, never describe a US LLC as "tax-free." State-level taxes, sales-tax nexus (triggered by selling to US customers above certain thresholds) and local franchise taxes can all apply independently of the federal position. A Delaware LLC with no Delaware operations pays no Delaware income tax but still owes the US$300 franchise tax. A company selling into Texas or California may trigger sales-tax collection obligations based on economic nexus rules. These layers are precisely why a qualified US tax adviser, not a formation agent, should confirm your position each year.

EIN, banking and the practical setup

You obtain an EIN by filing Form SS-4 with the IRS. No SSN or ITIN is required. Foreign applicants can apply by fax or, in some cases, by phone through the IRS international line, though processing times vary and can stretch to several weeks in 2026.

Opening a US bank account as a non-resident is the step that causes the most friction. Most major US banks require an in-person visit, a US address (your registered agent's address usually will not suffice) and extensive KYC documentation. Mercury, Relay and a handful of fintech-friendly banks accept remote applications from non-residents, but approval is not guaranteed and policies shift frequently. Cosmos coordinates this process with banking partners who are accustomed to onboarding foreign-owned entities, which removes much of the back-and-forth.

The practical formation sequence looks like this:

1. Choose your state and entity type.
2. File articles of organisation (LLC) or incorporation (C-corp) through a registered agent.
3. Obtain your EIN via Form SS-4.
4. Open a US bank account.
5. Engage a US CPA for annual filing obligations (Form 5472 for LLCs, Form 1120 for C-corps).

What changed in 2026: BOI reporting removed for US companies

Under FinCEN's August 2026 final rule, Corporate Transparency Act beneficial-ownership information (BOI) reporting no longer applies to companies formed in the United States. Only entities formed abroad that register to do business in a US state are now required to file BOI reports. This is a significant reversal from the original 2024 requirements, and most online guides have not caught up.

If you are forming a new US LLC or C-corp in 2026, you have no federal BOI filing obligation. If you previously filed a BOI report for a US-formed entity, no updates are required. Be cautious with outdated advice: many formation platforms still reference BOI as a mandatory step for domestic companies, which is no longer accurate as of this rule change.

When a US entity is the wrong move

A US company earns its place in a structure when you need one or more of the following: US-dollar banking, US-based investors, credibility with US enterprise clients, or access to US payment processors. If none of those apply, the US entity is overhead without a purpose.

A founder based in the UAE with clients exclusively in the Gulf, billing in AED or USD through a local free-zone entity, gains nothing from a Wyoming LLC except an extra set of filings and a CPA bill. The same applies to a European SaaS founder selling to EU customers through a Dutch or Irish entity: adding a US LLC "for the brand" creates compliance cost with no commercial return.

The honest test: will this US entity receive revenue, hold a bank account that you actively use, or sit on a cap table that a US investor needs to see? If the answer to all three is no, keep your structure simple. A UAE free-zone company or your home-jurisdiction entity will serve you at lower cost and lower risk.

How Cosmos helps

Cosmos advises on multi-jurisdictional structuring and coordinates US company formation through licensed US partners, including CPAs and registered agents. The service is not a self-serve formation tool: it is advisory-led, designed for founders and operators who need the US entity to fit into a broader structure that may include a UAE holding company, a UK trading entity or an offshore IP vehicle.

Where Cosmos adds particular value is in connecting the dots between jurisdictions. Choosing between a Wyoming LLC and a Delaware C-corp is one decision; ensuring the intercompany agreements, transfer-pricing logic and annual filings across two or three countries are consistent is the harder problem. Cosmos handles the coordination so that your US CPA, your UAE auditor and your UK accountant are all working from the same structure document.

Frequently asked questions

• Can a foreigner own a US LLC? Yes. There is no restriction on foreign ownership of a US LLC. A non-resident individual or a foreign company can be the sole member or one of multiple members.
• Do I need to visit the US to register a company? No. Formation, EIN application and registered-agent appointment can all be completed remotely. Banking may require additional steps depending on the institution.
• Is a US LLC tax-free for non-residents? Not automatically. A foreign-owned LLC with no US trade or business activity generally owes no US federal income tax, but filing obligations (Form 5472) remain, and state-level taxes or sales-tax nexus may apply.
• What is the cheapest state to form an LLC? Wyoming and New Mexico have among the lowest formation and maintenance costs. Delaware is standard for C-corps but carries a US$300 annual franchise tax for LLCs.
• Do I still need to file BOI reports in 2026? Not if your company was formed in the US. Under the August 2026 FinCEN rule, only foreign-formed entities registered in a US state must report.

The right US entity, formed in the right state, with the right filing support, is a genuine asset in a cross-border business structure. The wrong one is an expensive distraction. If you are weighing whether to register a US company as a foreign founder, start with the commercial reason, not the cheapest filing fee. Cosmos can help you map the structure, connect you with qualified US advisers and ensure every filing obligation is covered from year one.
