Do You Need to Be a U.S. Citizen to Start a Business in the United States?
A founder in Lagos, Manila, or São Paulo has U.S. customers and wants a U.S. company to serve them. She reads that she needs a green card, then that she doesn't but needs a U.S. address, then that Wyoming means no taxes and an EIN is impossible without a Social Security Number. Almost none of that is right, and the confusion sends founders to the wrong state, the wrong entity, and sometimes into a filing obligation they never knew about.
The short answer is no. You generally do not need to be a U.S. citizen, a green-card holder, or a U.S. resident to form and own a U.S. business. Citizenship is rarely the obstacle. What shapes the outcome is which entity you choose, where you form it, what reporting your ownership triggers, where the business operates, and separately, whether you may work in it while in the United States.
You Can Own a U.S. Company From Abroad
State law is unambiguous. Delaware allows any person to form a corporation "without regard to such person's or entity's residence, domicile or state of incorporation" (Del. Code Ann. tit. 8, § 101), and the LLC statutes of Delaware, Wyoming, Nevada, and North Carolina each let "one or more persons" form an LLC with no citizenship qualifier. A founder abroad can be a shareholder, a manager, and an officer or director, and can run the business without relocating.
Where the rule bends. Some sectors restrict foreign ownership directly; broadcast and common-carrier radio licenses face alien-ownership caps (47 U.S.C. § 310), and a U.S. air carrier must be 75% owned by U.S. citizens (49 U.S.C. § 40102). CFIUS may review transactions resulting in foreign control of a U.S. business (50 U.S.C. § 4565). And sanctions law applies to everyone: a founder or counterparty who is a designated person, or sits in a sanctioned jurisdiction, changes the analysis.
LLC, C-Corporation, or S-Corporation?
The LLC suits closely held and online businesses: fewer formalities, flexible management. The critical point is that its federal tax treatment is not fixed by its state-law form. Under the "check-the-box" regulations, a single-member LLC is disregarded by default, and a multi-member LLC is a partnership by default, and either can elect corporate taxation (26 C.F.R. §§ 301.7701-2, -3).
The C-corporation is a separate taxpayer, taxed at a flat 21% (26 U.S.C. § 11), with a second layer when profits are distributed. It is the customary vehicle for issuing stock and raising venture investment market practice rather than a legal requirement, but a real consideration if financing is the plan. No federal rule limits foreign ownership of one.
The S-corporation is generally unavailable. To qualify, a corporation may not have a nonresident alien as a shareholder (26 U.S.C. § 1361(b)(1)(C)). The test is tax residency, not citizenship: a non-citizen with a green card, or who meets the substantial-presence test, is a resident alien and an eligible shareholder (26 U.S.C. § 7701(b)). A founder living abroad is typically a nonresident alien, and the bar carries over to an LLC electing S treatment.
So the real choice is between an LLC and a C-corporation, and neither is universally better; that trade-off is what our business formation services exist to work through.
Owning the Company Is Not Permission to Work in It
U.S. immigration law regulates work performed inside the United States, not equity ownership. It is unlawful to employ an unauthorized alien here, and "unauthorized" is defined by immigration status, not by who owns the company (8 U.S.C. § 1324a); "employment" means services performed within the United States for remuneration (8 C.F.R. § 274a.1).
Holding equity or investing raises no work-authorization question, whatever your status or location.
Managing the business from abroad likewise raises none; immigration law concerns activity inside the country.
Visiting for business meetings, negotiations, and conferences is generally permissible, but does not extend to labor or services for hire (22 C.F.R. § 41.31).
Performing work in the United States, even for a company you wholly own, requires an immigration status that permits it. Ownership does not supply one.
Whether a particular person may work here depends on visa classification and status fact-specific and outside our scope as business counsel. If that is your question, consult qualified immigration counsel.
Getting an EIN Without a Social Security Number
Three numbers, three purposes. An SSN identifies individuals eligible for Social Security; an ITIN goes to an alien individual ineligible for an SSN who needs a taxpayer number for filing; an EIN identifies the entity.
You do not need an SSN or an ITIN to obtain an EIN. Neither section 6109 nor its regulation conditions issuance on holding either, and the IRS issues EINs to foreign persons (26 U.S.C. § 6109; 26 C.F.R. § 301.6109-1).
Form SS-4 requires a "responsible party" under current instructions to be a natural person who controls the entity, not another company. Where that person has no SSN or ITIN, the instructions direct a specific entry rather than a blank, and such applicants generally apply by fax, mail, or telephone rather than online.
You will need an ITIN not for the EIN, but when you personally must be identified on a U.S. return, if you must file one, or claim treaty benefits (Form W-7).
The Tax Question Has No Single Answer
Forming a U.S. company produces no uniform tax result, and the key insight is that a filing obligation and a tax bill are different things.
Consider the trap that catches the most foreign founders. A single-member LLC is normally disregarded for income tax. But one wholly owned by a single foreign person is treated as a domestic corporation for one narrow purpose: section 6038A reporting (26 C.F.R. § 1.6038A-1). It must file an annual Form 5472 with a pro forma Form 1120. Because the sole owner is a related party, contributions and distributions are reportable, including the money used to fund the company at the start. The usual exceptions do not apply, and failure to file carries a $25,000 penalty (26 U.S.C. § 6038A). An LLC with no U.S. trade or business can owe no tax and still owe this filing.
Withholding is the other recurring flag: a multi-member LLC taxed as a partnership must withhold on a foreign partner's share of effectively connected income (26 U.S.C. § 1446), and C-corporation dividends to a foreign shareholder generally face 30% withholding, reducible by treaty.
One piece of good news: under FinCEN's current rule, effective August 14, 2026, only foreign-formed entities registered to do business in a U.S. state are "reporting companies" for beneficial-ownership purposes; U.S.-formed entities are exempt (31 C.F.R. § 1010.380). The statute remains on the books, so confirm the position before relying on it.
Where Should You Form?
Delaware suits corporations expecting sophisticated governance and institutional investors. Its LLC pays a flat annual tax, recently raised to $400 for the 2026 tax year and billed in arrears (Del. Code Ann. tit. 6, § 18-1107); a corporation pays a variable franchise tax. For a small online business with no financing plans, that cost buys little.
Wyoming is low-cost and privacy-oriented: $100 to form an LLC, an annual license tax with a $60 floor, no state income tax. Members are not named in the public articles, but the company must still give its registered agent a natural-person contact, and any bank will require full beneficial-ownership information. "Anonymous LLC" oversells what Wyoming offers.
Nevada has no state income tax but is neither cheap nor private: articles, an annual list publicly disclosing managers, and a business license stack up.
North Carolina, or whichever state you actually operate in, is often the straightforward choice when you live or work there. Forming in Wyoming or Delaware does not eliminate home-state obligations: a company transacting business in North Carolina must obtain a certificate of authority and still faces state filings, fees, and taxes (N.C. Gen. Stat. § 55-15-01).
On the "tax-free state" idea: these states are attractive on state-level taxes only. That does not touch federal tax or obligations where you actually operate.
Your Formation State Is Not Your Tax Map
Keep three concepts separate: foreign qualification (registering to transact business in another state), state income-tax nexus, and sales-tax economic nexus. Since South Dakota v. Wayfair, 585 U.S. 162 (2018), physical presence is not required for the latter; the Court found South Dakota's threshold of more than $100,000 in sales or 200 transactions sufficient. Every state now has some version, with varying numbers.
How Your Business Model Changes the Analysis
Amazon FBA and marketplace selling. The live issue is inventory: goods in a fulfillment center are a classic physical-presence fact. Marketplace-facilitator laws make the platform the retailer for sales tax on facilitated sales (N.C. Gen. Stat. § 105-164.4J), but that does not absorb every obligation; inventory can still create income-tax or registration exposure.
Shopify and self-hosted e-commerce. No facilitator stands between you and the customer, so you are the retailer and must watch economic-nexus thresholds state by state.
SaaS and digital products. A Delaware C-corporation often makes sense where outside investment is planned, but not automatically provide entity-level tax and withholding. Let the financing plan drive the entity.
Agencies and services. Nexus turns on where services are performed and where you are present, not where your clients are, and performing them in the United States also implicates work authorization.
A Checklist Before You Form
Where will the business actually operate?
Will you run it from abroad, or work in the U.S. yourself?
LLC or C-corporation, and on what basis?
Are you seeking outside investment?
What federal reporting will foreign ownership trigger?
Which state has the strongest genuine connection to the business?
Will inventory, employees, or offices create obligations elsewhere?
What banking and address requirements will you face?
Is your industry regulated or sanctions-sensitive?
Do you need immigration or tax counsel alongside business counsel?
On the eighth question: citizenship is not legally required to open a U.S. business account (31 C.F.R. § 1020.220), but each bank sets its own practices, and being permitted to own a company does not guarantee one will accept you.
Where This Leaves You
You generally do not need to be a U.S. citizen or green-card holder to own a U.S. business. But choosing the right entity, state, and understanding the difference between ownership, taxation, reporting, and work authorization determines whether the structure serves you or causes problems later.
We work with founders outside the United States on entity formation, structuring, contracts, and the questions that follow, including through fractional general counsel services for companies needing ongoing support rather than a one-time filing.
