Guide de création de filiale américaine pour les entreprises étrangères

Every year, we watch the same pattern repeat: foreign company leaders arrive in the U.S., ready to capture market share, only to stumble on decisions that should have been straightforward. They form the wrong legal entity. They pick a state based on a misunderstanding about taxes. They hire the first executive who impresses them in an interview. Eighteen months later, they’re writing checks to lawyers to unwind structures that can’t scale.

Pact & Partners is a boutique executive search firm that helps foreign companies from 30+ countries recruit senior executives for U.S. operations. With consultants across all major US cities, we specialize in international-to-US executive placement. In 2025, net foreign direct investment into the United States reached record levels, with many countries significantly increasing their investment in American operations. The United States has established bilateral investment treaties with numerous countries to protect and facilitate cross-border investment. The ones that succeed don’t get lucky—they systematize the process. The ones that fail almost always miss the same critical decisions in the first eight weeks.

This is not a guide about the mechanics of incorporation. You can hire any corporate attorney for that. This is about why your structure matters, which decisions are irreversible, and how to avoid the expensive mistakes we see companies make repeatedly.

The Real Cost of Getting Your Structure Wrong

Your entity type and state of incorporation are not interchangeable decisions. They determine your tax exposure, your ability to raise capital, your access to treaty benefits, and what you can offer your first American executives. Change them later, and you’ll spend $50,000 to $150,000 in legal fees plus months of delay. Get them right on day one, and you move forward.

Important: Corporate formation, tax classification, and regulatory requirements vary by state and change frequently. Pact & Partners is an executive search firm, not a law firm, accounting practice, or registered agent. Consult qualified U.S. corporate attorneys and tax advisors before making any structural decisions.

According to the Delaware Division of Corporations, two-thirds of Fortune 500 companies incorporate in Delaware. In 2024, 81.4% of U.S.-based IPO companies chose Delaware. These aren’t stylistic preferences—they’re structural decisions rooted in decades of precedent. When you negotiate a Series A term sheet or an acquisition, the buyer’s legal team will not need to research unfamiliar state law. Your Delaware incorporation saves weeks of due diligence and removes structural risk from financing conversations.

You have four to six weeks to move from “we’re entering the U.S.” to “we’re operational.” After that, your competitors start winning customers and talent. The executives you want are signing offers elsewhere. Every week of delay is revenue you never recover. The question isn’t whether to rush—it’s how to move intelligently.

Why Structure Beats Speed

Intelligent speed doesn’t mean cutting corners on entity selection or skipping transfer pricing documentation. It means most foreign companies waste time on the wrong questions.

They debate between a C-Corp and an LLC for three months, consulting five different advisors. The market decision is obvious: if you’re raising U.S. capital or hiring executives, you need a C-Corp. If you’re holding real estate, an LLC works. Done.

They worry about incorporating in Delaware versus their operating state. Clear answer: Delaware, unless you’re operating in only one state with zero plans for outside investment or exit. The Delaware Court of Chancery handles corporate disputes in weeks, not years. Investors expect it. IPO-bound companies assume it.

What slows down most foreign companies isn’t legal complexity—it’s that they don’t understand what actually matters.

The Three Decisions That Actually Matter

First: Entity Type

We see three categories of foreign companies entering the U.S.

Companies seeking venture capital, private equity, or eventual IPO need a C-Corp. Full stop. Venture capitalists will not invest in LLCs. The preferred stock structures, convertible notes, and shareholder frameworks that define growth capital markets don’t work in LLC form. We’ve watched a Canadian software company waste six months trying to convince VCs to invest in an LLC structure. They finally incorporated as a C-Corp and raised their Series A in two months. The structure was never the problem. Their obstinacy was.

Companies holding real estate or conducting consulting work can consider an LLC. Pass-through taxation makes sense when you’re extracting capital rather than reinvesting it. But understand the trade-off: pass-through status still triggers U.S. tax filing for the foreign parent. An LLC owned by a foreign corporation doesn’t escape the IRS—it just changes the tax mechanics. And you’ll never issue stock options. Never attract growth capital. Never exit cleanly. We place CFOs into LLCs, and they discover these constraints too late.

Companies testing the market with one or two hires can use an Employer of Record service temporarily. Deel and Remote allow you to hire employees without incorporation. But here’s the hard truth: at around three to five employees, the cumulative EOR fees ($599–$1,000 per employee per month) exceed the cost of forming a subsidiary. If you plan to hire five Americans within 12 months, you’re already overpaying for the convenience of EOR.

Second: State of Incorporation

Delaware wins for 90% of foreign companies entering the U.S. The reasons are structural.

The Court of Chancery uses judges, not juries, to decide corporate disputes. These judges handle nothing but business cases and produce decisions in weeks rather than months or years. That predictability matters enormously when you’re negotiating a financing round or an acquisition. Your acquirer’s lawyers know exactly how Delaware courts interpret shareholder agreements, preferred stock provisions, and fiduciary duties. They won’t need expert testimony on unfamiliar state law.

The franchise tax is trivial: $400 minimum, capped at $200,000 even for massive companies. No state income tax on revenue earned outside Delaware. A subsidiary registered in Delaware but operating in Texas pays Delaware franchise tax plus Texas franchise tax—but not Delaware income tax on Texas revenue.

The precedent is unmatched. Six decades of Court of Chancery opinions have created a legal framework so well-established that every lawyer, investor, and judge in the country understands it.

Incorporate elsewhere only if you’re truly committed to a single-state operation with no plans to raise capital or eventually exit. If there’s any possibility of growth beyond your home state, Delaware costs almost nothing extra and provides enormous structural clarity.

Important: State incorporation and tax obligations are subject to frequent changes. Consult your U.S. corporate attorney and tax counsel before making final decisions.

Third: Your First American Executive

This is where we see the biggest gap between what foreign companies plan and what they execute.

Most assume they’ll manage the U.S. subsidiary from headquarters. That’s the error that creates everything else. American business culture does not accommodate time-zone separation. Fast decisions matter. Presence at meetings matters. Someone who can commit to your market without waiting for Copenhagen morning to make decisions matters.

The executives we place for foreign companies entering the U.S. typically fall into three categories: General Manager, VP of Sales, or CFO. Each serves a different market entry strategy.

A General Manager runs the entire U.S. operation from the beginning. This person is a generalist—part operator, part builder, part diplomat with your headquarters. They hire the next layer, establish the market presence, and own the success or failure of your entry. They cost between $200,000 and $350,000 in base salary, plus bonus and equity. They are the single most important hire you’ll make.

A VP of Sales makes sense if your product-market fit is already proven. Maybe you’re selling across borders from Europe and need someone to build the American distribution engine. This person costs $180,000 to $280,000 in base, plus commission. But here’s what we’ve learned: VP Sales roles for foreign companies fail when the candidate has never worked with a foreign headquarters. Cultural friction and unmet expectations compound monthly. The wrong VP Sales hire costs 5–15 times their annual salary when you factor in severance, lost revenue, and replacement recruitment.

A CFO is less common as a first hire but essential if your U.S. operations involve significant capital, fundraising, or complex intercompany structures. They ensure compliance, manage transfer pricing, and speak the financial language that American investors expect. They cost $250,000–$400,000.

We’ve seen companies get the legal structure perfect and then hire an executive who doesn’t understand working with a foreign parent. Eighteen months later, they’re starting over.

The Transfer Pricing Risk Nobody Takes Seriously

Important: Transfer pricing rules, IRS audit procedures, and penalty structures are subject to change and require specialist guidance. Consult a qualified transfer pricing specialist and U.S. tax counsel before your subsidiary operates.

If your U.S. subsidiary buys products from or pays management fees to the foreign parent, the IRS requires that these transactions occur at arm’s-length prices. That means the same price unrelated parties would charge. Transfer pricing violations are among the most common audit triggers for foreign-owned subsidiaries.

The IRS has dedicated transfer pricing teams. Penalties for non-compliance run 20% to 40% of the underpayment. These are not slap-on-the-wrist penalties. They’re meaningful financial exposure.

Most foreign companies ignore transfer pricing until they receive an audit notice. By then, they’re negotiating penalties and filing amended returns. The solution is simple: engage a transfer pricing specialist before your subsidiary operates. Document every intercompany transaction. Maintain contemporaneous pricing documentation. Review annually. The cost is $5,000–$15,000. The alternative is multiples of that in penalties and interest.

We’ve worked with companies that discovered transfer pricing gaps years after formation. One company paid $800,000 in penalties and interest on transfer pricing violations that could have been prevented by $8,000 in initial documentation and planning. Don’t be that company.

The Operational Timelines Nobody Gets Right

Most foreign companies underestimate how long it takes to move from “we’ve decided to enter the U.S.” to “we’re operational.”

Here’s what we tell them to expect:

Weeks 1-2: Engage U.S. legal counsel (budget $5,000–$15,000). Select a registered agent ($100–$300 annually, usually handled by your counsel). File formation documents. For a C-Corp, that’s Articles of Incorporation; for an LLC, a Certificate of Formation. Standard processing takes 3–7 business days in most states.

Weeks 2-3: Obtain an EIN from the IRS. If you have a U.S. Social Security Number, you can get this same-day online. If you’re a foreign applicant without an SSN, expect 4–6 weeks by fax or mail. This is a constraint most foreign companies don’t anticipate.

Weeks 3-4: Draft your operating agreement (LLC) or bylaws (C-Corp). Open a U.S. bank account. This is the step that consistently frustrates foreign founders. American banks have stringent Know Your Customer and anti-money laundering rules. Foreign-owned entities face enhanced due diligence. Mercury, the fintech platform backed by FDIC-insured banks, specifically targets foreign founders and allows fully remote account opening. JPMorgan Chase and HSBC work with foreign-owned subsidiaries, but often require in-person visits.

Weeks 4-5: Register for state taxes (sales tax, payroll tax, state income tax). This varies by state. Some states allow online registration in one day. Others take weeks.

Weeks 5-6: Set up payroll and benefits. Engage a payroll provider (Gusto, ADP, Rippling). Set up workers’ compensation, health insurance, 401(k) if offering.

Weeks 6-8: Hire your first U.S. employee. This is where most timelines collapse. If you’ve planned for the right executive, you’ve been recruiting for the past 4–6 weeks (in parallel with incorporation). If you haven’t, you’ll spend another 8–12 weeks searching.

Most foreign companies move from initial decision to operational subsidiary in 6–8 weeks if they’re organized. They take 12–16 weeks if they’re deciding on entity structure while recruiting. The winners parallelize. They form the entity while the executive search runs. They don’t wait for incorporation to finish, then begin recruiting.

What Companies Get Wrong

We’ve watched three patterns among companies that struggle:

First: They incorporate as an LLC, thinking pass-through taxation will save them money on federal taxes. This misunderstands how U.S. tax law treats foreign-owned pass-through entities. The subsidiary itself doesn’t pay federal income tax, but the foreign parent still files a U.S. return on the subsidiary’s U.S.-source income. The benefit is smaller than expected. And they’ve sacrificed the ability to offer stock options, raise institutional capital, and structure equity cleanly. We see this regularly with European companies where their home-country accountant influenced the decision. It’s almost always wrong.

Second: They choose a state based on lower filing fees or a misunderstanding about taxes. A company told us they wanted to incorporate in Nevada because “Nevada has no state income tax.” True. But they operate in California. So they’ll pay California income tax on their California revenue anyway, plus Nevada annual filing fees. The structure bought nothing. Delaware would have cost them $89 to incorporate and purchased them predictability, investor confidence, and decades of established legal precedent.

Third: They manage the subsidiary remotely without a local American leader. The founder stays in Berlin or Toronto. The CFO in headquarters makes major decisions. They hire a VP Sales who reports to the European VP of Sales, not a U.S. General Manager. The result: slow decisions, cultural friction, executives getting frustrated and leaving. The American market punishes decision-making that requires 8-hour time zone coordination.

Important: Tax obligations vary dramatically by state and entity type. Consult your U.S. CPA and corporate counsel before finalizing your structure and state registration.

The State Tax Reality Most Advisors Gloss Over

Your state of incorporation is not your state of taxation. Understand this distinction.

Forty-four states levy corporate income tax. Rates range from roughly 2% in North Carolina to 11.5% in New Jersey. Most fall between 4% and 8%. Six states—Wyoming, Nevada, South Dakota, Texas, Ohio, and Washington—have no traditional corporate income tax. But Texas levies a franchise (margin) tax on revenue above $2.47 million. So “no income tax” is true but incomplete.

Choose your operating state carefully. If you have a manufacturing facility in Texas and significant revenue there, you’re paying Texas tax on that revenue regardless of where you incorporate. Incorporating in Delaware doesn’t eliminate state taxes in your operating states. It just prevents duplicate taxes in Delaware.

If your U.S. subsidiary will serve multiple states—sales from New York, operations in Texas, development in California—you’re paying income tax in each state where you have what the IRS calls “nexus” (employees, customers, property, revenue). Incorporating in Delaware costs you only the Delaware franchise tax ($300–$400 annually). It saves you the uncertainty of unfamiliar state courts and the doubt that comes with a state where no precedent exists for your business questions.

A Contrarian Take on EOR

Everyone in the startup world will tell you: use an EOR to test the market, then form a subsidiary once you’re committed.

We disagree. Or more precisely: we disagree for the wrong reasons.

EORs like Deel and Remote have improved dramatically. They’re cheaper than they were five years ago. Remote account opening is now standard. You can onboard an employee in 48 hours without incorporation.

But here’s what we see: companies that start with an EOR tell us they’ll “transition to a subsidiary once we hit three employees.” Almost none do. They get comfortable with the EOR relationship. The vendor handles payroll and compliance. The founder doesn’t think about it. By the time they realize they want to issue equity or offer better tax treaty benefits, they’re running six employees on the EOR platform and the transition feels expensive and complicated.

The breakeven is closer than companies think. At three to five employees, the annual EOR cost ($36,000–$60,000) exceeds the cost of subsidiary formation ($15,000–$50,000 initial legal, then $10,000–$25,000 annually). You’re not saving money with EOR once you scale past that point. You’re paying a convenience premium and losing control.

Our contrarian take: if you know you’ll hire more than three Americans in the next 12 months, incorporate immediately. Don’t use the EOR interim step. Yes, it takes 6–8 weeks. But you’ll save $20,000–$40,000 over the next year and retain full operational control.

If you’re genuinely testing the market with one or two contractors, EOR makes sense. For anything permanent, incorporate.

Federal and State Tax Obligations—What You Actually Need

Important: Federal tax rates, tax treaties, and state tax structures are subject to change. Consult your U.S. tax counsel and CPA to assess treaty benefits specific to your parent company’s country of residence.

The federal corporate tax rate is 21%, made permanent through at least 2033 by legislation signed in July 2025. This applies to all C-Corp net income regardless of the parent company’s nationality.

The United States has tax treaties with over 60 countries that reduce withholding rates on dividends, interest, and royalties paid from the subsidiary to the foreign parent. The U.S.–France treaty, for example, reduces dividend withholding from 30% to 5% for qualifying corporate shareholders. If your parent is in a country with a favorable treaty, this difference is massive. A Canadian parent and a Singaporean parent face different withholding rates. A German parent faces different rates than both. Have your tax counsel run the numbers for your specific country. Treaty benefits are substantial—don’t leave them on the table.

For state taxes, you’ll register in your operating state. Sales tax, payroll tax, state income tax. The complexity varies enormously. Texas requires payroll tax registration before you hire. California has intricate employment classifications. New York has different rules for different industries. This is where you hire a U.S. CPA, not your home-country accountant. The local knowledge matters.

Why CFIUS Matters (And When It Doesn’t)

Important: CFIUS jurisdiction, filing procedures, and review timelines are subject to policy changes. Consult your U.S. legal counsel if your subsidiary will operate in sensitive sectors.

The Committee on Foreign Investment in the United States reviews foreign investments for national security implications. If your subsidiary will operate in critical technology (semiconductors, AI, quantum computing), critical infrastructure (telecom, energy), or handle sensitive personal data, CFIUS review may apply.

Filing is technically voluntary for most transactions. But failing to file when CFIUS jurisdiction applies can result in retroactive review and forced divestiture. When TikTok’s parent ByteDance acquired Musical.ly, CFIUS eventually ordered a review and forced changes years later. The lesson: if there’s any question about whether CFIUS applies, file. The process is not as onerous as people think.

In February 2025, the administration announced expedited review for investments from allied nations. In February 2026, the Treasury launched a Known Investor Program to simplify repeat filings. If you’re a European or other allied company, the timeline is now shorter.

The Real Mistakes Companies Make

We’ve been doing this long enough to recognize patterns. Here are the most expensive ones:

Using home-country accounting standards. Your subsidiary must use U.S. GAAP (Generally Accepted Accounting Principles), not IFRS or your home-country standards. Companies that start with the wrong framework spend $15,000–$30,000 converting their books later. Had they started with U.S. GAAP from day one, the cost would have been $3,000–$8,000. American banks, investors, and partners will expect U.S. GAAP financials.

Ignoring transfer pricing from the beginning. Every payment between the subsidiary and the parent must be at arm’s-length prices with contemporaneous documentation. The IRS does not accept the excuse that you planned to document it later.

Underestimating total employment costs. A $200,000 salary costs significantly more. Add employer payroll taxes (7.65% for FICA/Medicare), health insurance ($17,500–$18,500 per employee in 2026), 401(k) match (typically 4–6% of salary), workers’ compensation insurance, and benefits administration. True employer cost is typically 125–140% of base salary. Most foreign companies are shocked when they run the numbers.

Skipping Directors and Officers (D&O) insurance. American executives expect D&O coverage as standard. It protects the individuals running your subsidiary from personal liability in lawsuits. Foreign companies that don’t offer it lose top candidates to competitors who do. Annual premiums typically run $3,000–$15,000 for a small subsidiary.

Waiting too long to recruit leadership. This is where foreign companies consistently move too slowly. The American market does not wait. Competitors are hiring the executives you need. Customers are signing with companies that move faster. Companies that spend six months deciding on entity structure and another three months recruiting have already lost a year of revenue and market position.

What To Do Right Now

If you’re seriously considering a U.S. expansion, move in the next 30 days. Not because speed is always good, but because the earlier you start, the earlier you can parallelize decisions.

The Final Word

We’ve been placing executives into foreign-owned subsidiaries. In executive search since 1987, with US placements since 2006, the legal and financial structures are important—we’ve spent thousands of words on them—but they’re not what determines success.

What determines success is focus. Clear decisions made quickly. The right American leader who understands both your foreign parent and the American market. Systems that prevent your headquarters from micromanaging U.S. operations across a time zone gap. Compliance and tax documentation built from day one, not retrofitted after an audit notice.

Most of the companies we see fail don’t fail because they picked the wrong state of incorporation. They fail because they waited too long to build an American leadership team. They fail because they didn’t understand transfer pricing. They fail because they thought remote management would work and discovered that American business culture doesn’t tolerate it.

Get the structure right. Hire the right leader. Move with pace. Those three things matter. Everything else is implementation.
