A client of mine — a mid-sized German industrial supplier — spent eight months and roughly $40,000 in legal fees trying to fix a US entity structure they had set up wrong the first time. They had moved fast, picked Delaware because someone at a conference told them to, and never stopped to think about whether a C-corporation was the right vehicle for a wholly-owned subsidiary with no plans to raise American venture capital. By the time they hired me, they had a dormant Delaware C-corp, a confused registered agent situation, and a German parent company that had no idea it had created a US permanent establishment risk. This story is more common than it should be.
The phrase “US subsidiary” gets used loosely. What most foreign founders and executives mean is a domestic legal entity — typically a corporation or LLC — that is wholly or majority owned by a non-US parent. The parent might be a GmbH in Munich, a limited company in Lagos, or a private limited in Singapore. The subsidiary exists on American soil, can sign contracts, open bank accounts, hire employees, and conduct business without the parent needing to register in every state where it operates. That last benefit alone is often the primary motivation. But the path from that motivation to a properly functioning entity involves more genuine decision-making than most people expect.
The first real fork in the road is entity type, and it deserves more deliberation than it usually gets. A Delaware LLC offers pass-through taxation by default, flexible governance, and minimal ongoing formalities. A Delaware C-corporation offers a structure that US investors recognize and prefer, a clean separation of equity classes, and familiarity for American counterparties. For a foreign parent that simply wants a US operating presence — a sales office in Fort Lauderdale, a distribution hub in Tampa, a services team in Naples — the LLC is often the cleaner choice. There is no mandatory board structure, no requirement to issue stock, and the operating agreement can be drafted to give the foreign parent near-total control while still satisfying US legal requirements. The C-corp makes more sense when the subsidiary will eventually take on US investors, issue options to American employees under a qualified plan, or pursue an IPO. Conflating those two scenarios is where expensive mistakes begin.
Once entity type is settled, state of formation becomes the next question. Delaware remains the default recommendation, and for good reason: its Court of Chancery has centuries of corporate jurisprudence, its LLC and corporation statutes are predictable, and virtually every US attorney knows how to work within them. But formation state is not the same as operating state. A company formed in Delaware that does business in Florida — with a real office, employees, and revenue generated in-state — will need to foreign-qualify in Florida regardless of where it was formed. That means filing a Certificate of Authority with the Florida Division of Corporations, appointing a registered agent in Florida, and paying the applicable fees. Skipping this step does not make the obligation disappear; it just accumulates penalties and can create complications when the company tries to enforce a contract in a Florida court.
Foreign qualification is one of the most consistently overlooked steps in the whole process. A foreign parent setting up a subsidiary often treats the initial state filing as the finish line. In reality, if the subsidiary will operate in multiple states — and most growing companies eventually do — each state where it has a physical presence, employees, or meets that state’s economic nexus threshold will require its own registration. Florida’s threshold for triggering the foreign qualification requirement is fact-specific, but maintaining a single employee or leasing office space in Miami-Dade is generally sufficient. The filing itself is not burdensome; a Certificate of Authority for a foreign LLC in Florida currently runs $125. The burden is in knowing you need to file in the first place.
The Structural Details That Create Real Liability
Once the entity exists on paper, the foreign parent needs to think carefully about how it is capitalized and governed. Undercapitalization is one of the classic grounds on which a court will pierce the corporate veil — meaning creditors can reach through the subsidiary to hold the parent liable. This is not a theoretical risk. In industries like construction, professional services, and distribution, where contract disputes and tort claims are common, a subsidiary that is funded with just enough money to open a bank account but not enough to actually absorb business risk is a liability waiting to materialize. A reasonable initial capitalization depends on the scale of operations, but the principle is simple: fund the entity as though it is a real business, because it is.
Governance documentation matters more than most foreign parents expect. The operating agreement or corporate bylaws are not boilerplate to be downloaded and signed once. They need to address who has authority to bind the company, how decisions are made when the parent and subsidiary management disagree, what happens if a key US employee resigns, and whether the subsidiary can enter into contracts above a certain value without parent approval. I have seen subsidiaries in Florida where the only documented officer was a German managing director who had never set foot in the United States — and that entity was trying to open a commercial bank account. US banks, understandably, have questions about that arrangement. The IRS also has questions, specifically around whether the foreign parent has created a permanent establishment and whether the subsidiary’s income is being properly allocated under transfer pricing rules.
That brings up the tax dimension, which is genuinely complex and genuinely consequential. A US subsidiary of a foreign parent is a US taxpayer. It files its own federal return — Form 1120 for a C-corp, Form 1065 or a disregarded entity return for an LLC — and it must pay US corporate income tax on its US-source income. But the parent-subsidiary relationship creates additional obligations: intercompany transactions must be priced at arm’s length, any payments from the subsidiary to the parent (royalties, management fees, interest on loans) must be documented and defensible, and withholding taxes may apply to those payments depending on the tax treaty between the US and the parent’s home country. The US-Germany tax treaty, for instance, reduces the withholding rate on dividends to 5% for corporate shareholders meeting an ownership threshold, compared to the standard 30%. That difference is not trivial when dividends start flowing.
The practical sequence, for anyone working through this for the first time, runs roughly as follows. Decide on entity type based on the actual business purpose, not on what someone heard at a conference. Choose a formation state — Delaware for most situations, the home operating state when simplicity matters more than flexibility. Engage a registered agent in both the formation state and any state where operations will be based. Draft governance documents that reflect how the business will actually be run, not a generic template. Open a US bank account with proper documentation of the entity’s ownership structure and beneficial owners, which under FinCEN’s Customer Due Diligence rules now requires disclosing any individual owning 25% or more. File for an Employer Identification Number, which a foreign-owned entity can obtain even without a US Social Security Number as the responsible party. And before the first dollar changes hands between the subsidiary and the parent, get a tax attorney to review the transfer pricing implications.
None of this is exotic or inaccessible. The US entity registration process is genuinely one of the more welcoming in the world for foreign businesses. But welcoming does not mean frictionless, and fast does not mean right. The German industrial supplier I mentioned at the start eventually got their structure sorted — a Delaware LLC, properly capitalized, foreign-qualified in Florida, with a clean intercompany services agreement and a transfer pricing policy their auditors could defend. It took another six months to fix what should have been built correctly the first time. The cost of doing it right initially would have been a fraction of the cost of doing it over.
