Forming a U.S. LLC as a non-U.S. founder (2026)

Overview

This guide is for founders who live outside the United States and want to run a U.S.-registered entity: typically a single-member LLC used for a SaaS product, an e-commerce storefront, a freelance consultancy, or a holding structure for U.S. contracts. It is not legal or tax advice — it is the shape of the problem, and the 2026-accurate mechanics that tend to trip up first-time international owners.

Step 1: Pick a state, carefully

For a non-U.S. founder with no U.S. physical presence, the state choice is narrower than the usual Delaware-vs-Wyoming debate suggests.

• Wyoming is the common default. $100 filing fee, $60 annual report (minimum), no state income tax, no publication requirement, strong privacy (members are not named in the public filing), and a mature commercial registered-agent market that specifically serves international clients.
• Delaware is the other serious answer, but mostly for companies that will later take venture capital or convert to a C-Corp. The $300 annual franchise tax and the extra sophistication of the Court of Chancery are overkill for a cash-flowing small business. If you are not planning a priced equity round, Delaware is not obviously better.
• New Mexico has one genuine advantage: no annual report at all, and low filing fees. It has become popular with digital nomads for that reason.
• Nevada and Florida are sometimes recommended but have higher recurring costs (Nevada's state business license is $200/year; Florida's annual report is $138.75 and late fees are punishing).

States to avoid as a non-U.S. founder with no physical presence there: California (the $800 minimum franchise tax applies to any LLC "doing business" in CA — a loose standard), New York (the publication requirement costs $1,000–$2,000 in many counties), and any state where you do not live and have no customers or operations.

A note on "nexus." Where you form the LLC does not, by itself, determine where the LLC owes taxes. Nexus — the connection that obliges you to file and pay — is created by operations, employees, inventory, or in some states enough revenue. A Wyoming LLC that warehouses inventory in California has California nexus regardless of formation state. Form where the mechanics are clean; pay tax wherever your activity creates nexus.

Step 2: Registered agent (required, non-negotiable)

Every U.S. state requires an LLC to maintain a registered agent with a physical street address in that state. As a non-U.S. founder, you cannot be your own agent, because you do not have a U.S. street address. You hire a commercial registered agent.

Typical cost: $100–$200 per year. The major commercial agents (Northwest Registered Agent, Harbor Compliance, Registered Agents Inc.) all serve international clients; several smaller state-specific agents in Wyoming, New Mexico, and Delaware specifically market to non-U.S. founders.

What the agent does is narrow: accepts service of process (lawsuits) and official state mail on behalf of the LLC, then forwards it to you. Most bundle a mail-forwarding or scan-to-email service for an extra fee — useful, because the IRS and the bank will send physical mail.

Step 3: File the LLC

Once you have a state and an agent, the filing itself is anticlimactic. In Wyoming, you submit Articles of Organization through the Secretary of State's online portal, pay the $100 fee, and receive a confirmation within minutes to a few hours. The filing asks for:

1. The LLC's name (must be distinguishable; must contain "LLC" or a variant).
2. The registered agent's name and Wyoming address.
3. The principal office address (this can be your foreign address).
4. The organizer's name and signature (this can be you, or the registered agent acting as the organizer on your behalf).

You do not have to disclose the members. Wyoming does not ask for beneficial ownership in the public filing. You will, however, need to report beneficial ownership separately to FinCEN — see step 6.

Step 4: Get an EIN without a Social Security Number

The Employer Identification Number is the federal tax ID. You need it to open a bank account, accept payments through most U.S. processors, and file the required foreign-owned LLC returns. For U.S. applicants, you apply online at irs.gov and receive the EIN instantly. For foreign applicants without a Social Security Number or ITIN, the process is different and slower.

Your route is Form SS-4, submitted by fax or mail to the IRS's international unit. Fax is faster (4–6 business weeks in 2026 conditions; mail is 6–12).

The critical fields:

• Line 7b: enter "Foreign" where it asks for SSN/ITIN of the responsible party. This is the specific phrase the IRS accepts; any other value causes rejection.
• Line 8a: LLC.
• Line 9a: check "Other" and write "Foreign-owned U.S. disregarded entity" if you are a single-member LLC with a non-U.S. owner. If you have elected C-Corp or partnership treatment, select accordingly.
• Line 18: the third-party designee box — fill this in only if you are using a formation service to submit on your behalf.

Submit to the fax number listed in the Form SS-4 instructions for international applicants (this number is maintained at the IRS's "Apply for an EIN" page and updates occasionally). Include a cover page that includes a return fax number — the EIN is returned by fax to the number you provide.

Do not use the online EIN application (EIN Assistant) if your responsible party is a foreign person without an SSN or ITIN. It will appear to work and then reject at the last screen. Fax is the correct channel.

You do not need an ITIN to get an EIN. These are separate numbers with separate purposes: an EIN identifies the entity, an ITIN identifies the person. Many founders chase an ITIN first because of bad advice online; most never need one.

Step 5: When you actually need an ITIN

An Individual Taxpayer Identification Number is a personal U.S. tax ID for people ineligible for an SSN. You need one if:

• You are a member of a multi-member LLC that files Form 1065 (each member receives a Schedule K-1, which requires a taxpayer ID).
• You personally have U.S.-source income that is not covered by a W-8BEN treaty claim (for example, rental income from a U.S. property you hold personally).
• You are claiming a refund of U.S. tax that was over-withheld.

You do not need an ITIN if you are the sole member of a single-member LLC treated as a disregarded entity and your income does not otherwise require U.S. personal filing. The LLC has an EIN; that is the tax ID that matters.

ITINs are applied for via Form W-7, typically alongside a tax return. The application requires a certified copy of your passport — either notarized by a U.S. Certifying Acceptance Agent abroad, or mailed to the IRS in original form. Processing is 8–14 weeks. Most international founders route this through a Certifying Acceptance Agent to avoid mailing their passport.

Step 6: The FinCEN beneficial ownership report

Since 2024, the Corporate Transparency Act requires most U.S. entities — including LLCs formed by non-U.S. owners — to report their beneficial owners to FinCEN (the Financial Crimes Enforcement Network). The report is called a Beneficial Ownership Information (BOI) report.

As of early 2026, the regulatory landscape here is in flux: a March 2025 Treasury ruling exempted most U.S.-formed entities owned by U.S. persons from the reporting requirement, but foreign-owned U.S. entities remain in scope under the revised rule. If you are a non-U.S. person who owns a U.S. LLC, assume you need to file.

The BOI report requires:

• Your full legal name, date of birth, residential address, and a scanned image of your passport or another acceptable ID.
• The same information for every other beneficial owner (anyone holding 25%+ or exercising substantial control).
• The LLC's formation details.

Filing is free at fincen.gov/boi. There is no annual renewal — you file once at formation and then only when information changes (an address, a new owner). Civil penalties for non-compliance are steep ($591/day as adjusted for 2026 inflation), and there are criminal penalties for willful failure.

The CTA and its foreign-owned rule have been challenged in court and may change. Check fincen.gov/boi for current guidance before filing. As of early 2026, the position is: foreign-owned LLCs file; U.S.-owned LLCs do not.

Step 7: Open a U.S. bank account (the hard part)

This is where most non-U.S. founders stall. Traditional U.S. banks — Chase, Bank of America, Wells Fargo — typically require the beneficial owner to appear in person at a U.S. branch, often with a valid visa stamp. For a founder who cannot easily fly to the States, this is a wall.

The practical options in 2026:

• Mercury (mercury.com): the most common route for foreign-owned LLCs. Fully remote onboarding, accepts a non-U.S. passport and residence, no monthly fees, integrates with Stripe and the common accounting tools. Mercury has tightened its acceptance criteria over time — they decline many single-person consultancies and prefer companies with revenue or a clear business model — but for most tech-adjacent founders, it is the first answer.
• Relay (relayfi.com): similar remote-first posture, slightly more generous on the kinds of businesses they accept.
• Wise Business (wise.com): useful for multi-currency operations; technically not a bank but a licensed money-services business. Good for receiving payments in multiple currencies and converting cheaply. Limitations on deposit insurance and on the kinds of U.S. financial transactions you can do.
• A U.S. trip: if you can make one, a single visit on a tourist visa with your passport, EIN confirmation letter, Articles of Organization, and operating agreement is usually enough to open a Chase or Bank of America account at a branch. Some branches are more welcoming than others.

What to have ready for any of these:

• EIN confirmation letter (IRS CP-575 or the fax copy).
• Filed Articles of Organization from the state.
• Operating agreement (self-drafted is fine; must name you as the member).
• Your passport.
• Proof of your non-U.S. address (utility bill, bank statement).
• A clear description of what the business does and expected transaction volume.

Step 8: The U.S. tax picture, compressed

This is the section where founders get bad advice most often. A compressed, 2026-accurate version:

A single-member LLC owned by a non-U.S. person is, by default, a "disregarded entity" for federal tax purposes. The LLC itself does not file a Form 1065 or Form 1120; its income flows to the owner. What the LLC does file:

• Form 5472 attached to a pro-forma Form 1120, annually. This applies to any U.S. disregarded entity with a foreign owner and any "reportable transaction" — which is almost any movement of money in or out. It is informational, not a tax return. Penalty for not filing is $25,000 per year. Most international founders are unaware of this form until their accountant finds it, and the penalties stack quickly.
• If the LLC's activity rises to a U.S. trade or business and generates effectively connected income (ECI), the foreign owner owes U.S. tax on that income personally and must file Form 1040-NR.

The key question is whether you have a U.S. trade or business. The IRS's standard is fact-intensive: a foreign person selling software from abroad to U.S. customers, with no U.S. employees, office, or dependent agent, is typically not engaged in a U.S. trade or business, and income is not ECI. A foreign person with a U.S. warehouse and U.S.-based salespeople typically is. The grey area is large — Amazon FBA sellers in particular have spent a decade arguing with the IRS about whether FBA creates ECI. Do not rely on internet summaries for this question; it determines whether you owe U.S. federal income tax at all.

State tax is a separate layer. Wyoming and a handful of other states have no income tax, which is one reason Wyoming is popular. But if your LLC has nexus in another state — inventory in California, a contractor in New York — you may owe state tax and be required to register as a foreign LLC in that state.

Step 9: Tax treaties — what they actually do

The United States has tax treaties with roughly 70 countries. Founders sometimes assume that "my country has a treaty, therefore I pay no U.S. tax." This is almost never correct. What treaties typically do:

• Reduce withholding on certain passive U.S.-source income (dividends, interest, royalties) to a lower rate than the 30% default.
• Define a permanent establishment (PE) threshold higher than the U.S. "trade or business" standard. Under most treaties, a foreign resident is only taxable on business profits if they have a PE in the U.S. — typically a fixed place of business or a dependent agent with authority to conclude contracts. This is a meaningfully higher bar than ECI.
• Resolve dual residency questions (tie-breaker rules if you might be a tax resident of both countries).

To claim treaty benefits, you file Form W-8BEN (for individuals) or W-8BEN-E (for entities) with any U.S. payer — Stripe, Amazon, a U.S. client, a U.S. bank. The W-8 is how you tell the payer "I am a non-U.S. person, withhold at the treaty rate (or zero for business profits without a PE)."

The three most common mistakes:

1. Not filing a W-8 at all. Payers who do not receive a W-8 default to 30% backup withholding on gross payments, and recovering it is painful.
2. Claiming treaty benefits your country's treaty does not actually provide. Not every treaty looks the same; some are narrower than others. Read your specific treaty, or have it read, before claiming.
3. Misreading "business profits" as covering everything. If you personally are a U.S.-source service provider (consulting for a U.S. client while physically present in the U.S.), treaty protection is narrower than many founders assume.

Step 10: Accepting payments

Once you have the LLC, the EIN, and a bank account, payment processors are comparatively easy.

• Stripe accepts foreign-owned U.S. LLCs. You sign up with the LLC's EIN, provide your personal passport and address as the beneficial owner, and Stripe handles the W-8 internally. U.S.-LLC Stripe accounts can accept U.S. cards at standard rates and settle into Mercury or Relay.
• PayPal Business similarly works; some international founders report slower onboarding.
• Wise Business can receive USD wires and ACH directly, which is useful if you want to keep banking relationships minimal.

Ongoing compliance, briefly

• State annual report: Wyoming charges $60 (minimum) by the first day of the anniversary month. Miss it by 60 days and the state dissolves the LLC administratively.
• Registered agent renewal: annual, $100–$200.
• Federal Form 5472 / pro-forma 1120: annual, due April 15 (with automatic extension to October 15 available). $25,000 penalty if missed.
• FinCEN BOI update: only if information changes (address, ownership).
• State sales tax: if you have nexus in any state, register and collect. Wayfair (the 2018 Supreme Court decision) means most states can require sales tax collection based on revenue or transaction thresholds, not physical presence. This is frequently the single largest ongoing compliance burden for e-commerce sellers.

The sequence, compressed

1. Hire a Wyoming registered agent ($100–$200/yr).
2. File Articles of Organization in Wyoming ($100).
3. Fax Form SS-4 to the IRS international unit for the EIN (4–6 weeks).
4. File FinCEN BOI report (free, 15 minutes).
5. Open Mercury, Relay, or Wise Business (1–3 weeks).
6. Sign up for Stripe / payment processors as needed.
7. Understand your U.S. trade-or-business / ECI / treaty position before your first U.S. revenue. Ideally with a CPA who handles foreign-owned LLCs.

None of this is exotic. The only step most founders underestimate is the EIN fax — because it requires sending an actual fax, and because the IRS international unit takes weeks — and the Form 5472 filing, which they do not learn about until an accountant surfaces it. Plan for both.

What this guide is not

It is not tax advice for your specific situation. The U.S.-trade-or-business question, the choice of whether to elect C-Corp treatment (a reasonable move for founders who want to reinvest profits and shield personal exposure), and the tax-treaty analysis are all fact-specific. For any non-trivial revenue level, a U.S. CPA who specifically handles foreign-owned LLCs is worth a retainer. The savings on a single correct treaty claim or a single avoided penalty typically exceed the fee.
