Non-US Founder, US Company: When You Actually Need One
Most non-US founders are funnelled toward a Delaware C-Corp by formation services that earn the same fee whichever entity you pick. For a meaningful share of them, it is the wrong default. This piece walks the actual decision: when a non-US founder genuinely needs a US company, which entity makes sense if you do, and the compliance bill that arrives after the formation invoice is paid.

TL;DR
- A US entity is genuinely required only if you are raising from US institutional investors, selling into US enterprise procurement that demands a US vendor, or you need a true US business bank account that fintechs cannot replicate.
- For everyone else, a UK Ltd, Singapore Pte Ltd, Estonia OÜ, or your home-country entity plus Stripe will usually do the job.
- If you do form in the US, a single-member Wyoming LLC owned by a non-resident alien is often cheaper and simpler than a Delaware C-Corp, with one important catch (Form 5472).
- A Delaware C-Corp is the right call only when US fundraising is in scope inside 18 months. Otherwise its 21% federal corporate tax and double-taxation profile work against you.
- Formation is the cheap part. Annual professional fees of $1,500 to $5,000, Form 5472, FBAR, and potential GILTI exposure if you build a US-parent-foreign-subsidiary structure are where the real cost lives.
When you actually need a US entity (and when you don't)
There are three situations where a US company is genuinely the right answer for a non-US founder.
The first is raising from US institutional investors. Most US venture capital firms invest exclusively into Delaware C-Corps. Their fund documents, tax reporting, and template paperwork assume that structure. A US lead investor will typically request a "Delaware flip" before wiring funds, and that flip carries legal fees and possible tax events. If a US-led priced round is on your roadmap inside the next 18 months, incorporating in Delaware up front is almost always cheaper than flipping later.
The second is US enterprise procurement that requires a US vendor of record. Some large US buyers route invoices through accounts payable systems that only accept US-domiciled vendors, or apply 30% withholding to non-US payees that treaties only partially relieve. If your sales pipeline depends on those buyers, a US entity removes friction the alternatives cannot.
The third is a true US business bank account. Stripe processes payments for non-US companies in over 40 countries. Wise issues USD account details that work for receiving payments and converting at fair rates. For most founders, those tools are sufficient. The exception is significant USD treasury volume, US wire infrastructure, or banking relationships that genuinely require Mercury or Relay-grade onboarding tied to a US entity.
If none of those describe you, a US entity is usually a cost without a benefit. The honest test: write down the specific business problem a US entity would solve. "Stripe Atlas advertised it" or "everyone in YC has one" is not a problem. "My US lead investor's term sheet requires it" or "Salesforce procurement will not onboard a non-US vendor" is. A UK Ltd, Singapore Pte Ltd, Estonia OÜ, or your home-country entity will usually cover the rest.
If you do need one: Delaware C-Corp vs Wyoming LLC
Once you have decided a US entity is justified, the next question is which one. Most articles answer "Delaware C-Corp" and stop there. The actual answer depends on whether you are raising US capital.
Delaware C-Corp
The Delaware C-Corp is the default for venture-backed startups for a reason: investor-friendly corporate law, well-developed Court of Chancery precedent, and a structure every US lawyer and term sheet template is built around. The cost profile is roughly $400 minimum franchise tax plus $125 registered agent, so about $525 per year before professional fees. The trade-off is real corporate tax: 21% federal on profits, plus a 30% withholding tax on dividends paid to non-resident shareholders (often reduced by your country's tax treaty with the US, but rarely to zero).
Wyoming LLC
A single-member Wyoming LLC costs roughly $60 in annual report fees plus $50 to $150 for a registered agent, so $110 to $210 per year. By default, a single-member LLC is treated as a disregarded entity for US federal tax purposes. For a non-resident alien owner whose LLC has no US trade or business and no US-source effectively connected income, that means no US federal corporate tax at the entity level and no US individual return. The income flows through to the foreign owner, who reports it where they are tax resident.
The catch is meaningful. Foreign-owned single-member LLCs must file Form 5472 plus a pro-forma Form 1120 each year, regardless of revenue or activity. The penalty for non-filing is $25,000 per form, per year. Cheap formation services rarely surface this in checkout, and founders discover it the year after formation.
The other catch is investor friction. Most US venture investors will not invest into an LLC. Converting from an LLC to a C-Corp later runs $3,000 to $10,000 in legal fees, plus possible tax consequences on the conversion. If a US-led priced round is on your two-year horizon, the long-run cost of starting in WY and flipping is higher than starting in Delaware.
Trade-off summary
| Factor | Delaware C-Corp | Wyoming LLC (single-member, NRA-owned) |
|---|---|---|
| Annual entity cost | ~$525 ($400 franchise + $125 RA) | ~$110 to $210 ($60 report + RA) |
| US federal corporate tax | 21% on profits | None at entity level if no ECI; income flows to foreign owner |
| Dividend withholding | 30% on distributions (treaty may reduce) | Not applicable (disregarded) |
| Form 5472 obligation | Yes, with annual return | Yes, with pro-forma 1120 ($25k penalty for non-filing) |
| Investor compatibility | Standard for US VC | Most US VCs will not invest |
| Conversion to C-Corp later | Already a C-Corp | $3,000 to $10,000 legal fees |
The practical rule: if a US-led priced round is realistic within 18 months, start in Delaware. If you are self-funded and want a lightweight US presence for banking, payments, or US-facing contracts, Wyoming is usually the better fit, provided you actually file Form 5472.

The compliance bill formation services don't quote
Formation is the cheap part. The recurring cost lives in four places.
Form 5472. Any US corporation that is 25% or more foreign-owned, and any foreign-owned single-member LLC, must file Form 5472 reporting transactions with foreign related parties. Failure to file: $25,000 per form, per year. Routine with a cross-border CPA, but not optional.
FBAR (FinCEN Form 114). If your US company has signature authority over foreign financial accounts aggregating over $10,000 at any point in the year, FBAR is required. Penalties for non-willful violations routinely exceed $10,000 per violation; willful violations are far higher. Founders with existing home-country accounts often trigger this without realising.
GILTI on US-parent / foreign-subsidiary structures. If a US C-Corp owns your home-country entity as a subsidiary, the Global Intangible Low-Taxed Income regime can tax that subsidiary's earnings at an effective rate of about 10.5%, with an 80% haircut on the foreign tax credit. Even fully foreign-taxed earnings can leave residual US tax. The clean fix: keep entities parallel (US for US business, home-country for home-country business) rather than nesting them.
Effectively connected income. A C-Corp's operating income is taxed at 21% federal. A foreign-owned LLC with US-source ECI loses the disregarded-entity advantage: the foreign owner files Form 1040-NR and pays graduated US individual rates. Whether your activity creates ECI depends on facts (US employees, US-based servers, US-located inventory, fixed place of business) and is worth a one-hour conversation with a cross-border tax adviser before formation, not after.
Realistic annual professional fees: $1,500 to $5,000 for a US C-Corp; $500 to $1,500 for a Wyoming LLC with no US activity. Budget against those, not the formation fee.

US banking, briefly
The biggest practical friction for non-US founders is opening a US business bank account. Traditional banks (Chase, Wells Fargo, Bank of America) generally require an in-person branch visit, which makes them unworkable for most non-US founders.
Mercury is the most common neobank route. It accepts non-US founders, integrates well with Stripe, and is included in the Stripe Atlas formation package. Approval is not guaranteed; Mercury declines applications from certain countries and industries. Relay is a useful alternative, particularly for smaller or self-funded businesses. Wise Business is not a US bank account in the regulatory sense, but it provides USD account details (routing and account numbers) that work for receiving payments, and it is materially easier to open from outside the US.
If you can solve your banking with Wise plus your home-country business account, a US entity becomes harder to justify on banking grounds alone.
If you don't need a US entity: three alternatives
UK Ltd. Forms in 24 hours for under £50, no withholding tax on dividends, tax treaties with over 130 countries. Corporate tax is 19% on profits up to £50,000, 25% above £250,000, with marginal relief between. Suits European founders, founders selling globally with light admin tolerance, and anyone who does not need US-investor compatibility.
Singapore Pte Ltd. 17% headline corporate tax with the Start-Up Tax Exemption reducing the effective rate on the first S$200,000 of chargeable income for the first three years. Strong banking, no dividend withholding. The friction: Singapore requires at least one ordinarily resident local director, and nominee director services run roughly $1,500 to $3,000 per year. Best fit for Asia-facing businesses or founders who want a globally credible neutral jurisdiction.
Estonia OÜ. 0% corporate tax on retained earnings; 22% on distributions (the previously available reduced rate is no longer in force from 2025). The retained-earnings exemption is genuinely useful if you reinvest profits for years. The headline "0% tax" pitch is misleading once you take money out: your country of residence will typically tax the distribution as personal dividend income on top of Estonia's 22%. Best fit for location-independent founders comfortable planning around the distribution event.
For all three, the same caveat applies: corporate jurisdiction does not change personal tax residence. Your home country will tax dividends when they reach you, and CFC rules in your country may attribute the foreign company's profits to you regardless of distribution timing.

FAQ
Can I form a US company entirely online as a non-US resident?
Yes. Every major formation provider handles the entire process remotely, and you do not need to visit the US. The slow step is the EIN: for non-US applicants without a Social Security Number or ITIN, IRS processing typically runs 4 to 12 weeks. Some providers will fax-expedite the application, but the IRS sets the actual pace.
How does US tax apply to a non-US founder?
It depends on structure and activity. With a US C-Corp, the corporation pays 21% federal tax; dividends to non-US shareholders carry 30% withholding (often reduced by treaty). A non-US founder generally does not file a US individual return unless they have other US-source income or meet the substantial presence test. A foreign-owned single-member LLC with no US trade or business and no effectively connected income generally does not generate US income tax for the owner, but Form 5472 plus a pro-forma 1120 are still required annually.
What's the cheapest way to maintain a US entity?
A single-member Wyoming LLC: roughly $110 to $210 per year in entity costs, plus $500 to $1,500 in cross-border tax preparation and Form 5472 filing. All in, expect $600 to $1,700 per year. A Delaware C-Corp runs about $525 in entity costs plus $1,500 to $5,000 in professional fees, so $2,000 to $5,500 all in.
Is a US holding company that owns a foreign subsidiary usually a good idea?
Generally not. A US parent owning a foreign subsidiary triggers GILTI on the subsidiary's earnings at an effective rate of about 10.5%, with the foreign tax credit subject to an 80% haircut. Parallel entities (US for US business, home-country for home-country business) are usually cleaner. Exceptions exist for planned US IPOs and complex M&A structures; for most early-stage founders, parallel is the safer default.
Can I use Stripe without a US company?
Yes, in over 40 countries. Stripe accepts local entities in each supported country. A US entity helps specifically when you need US-optimised checkout features, want to settle in USD without conversion, or your home country is not yet on Stripe's supported list.
