The United States offers one of the world’s largest and most dynamic consumer markets, making it a prime target for international business expansion. However, establishing a legal presence through a US subsidiary is a complex, multistep process that foreign companies often need assistance with.
Companies must navigate many federal and state-specific laws, which can lead to significant administrative overhead and delays. Setting up a subsidiary USA requires careful planning and adherence to legal protocols. Understanding these requirements is essential for a compliant and successful market entry.
Key steps to establish a USA subsidiary
The process for setting up a subsidiary in the USA involves legal, financial, and administrative tasks that can take several months to complete. The exact steps and requirements vary depending on the state of incorporation and the nature of the business operations.
To establish a USA subsidiary, a company must complete the following key steps:
-
Choose an entity structure: International companies typically choose between a C-Corporation (C-Corp) or a Limited Liability Company (LLC). C-Corps are often preferred by foreign parent companies for their familiar corporate structure and straightforward tax treatment. LLCs offer more flexibility but can have more complex tax implications for foreign owners. Note that S-Corporations (S-Corps) are generally not available to foreign-owned entities due to shareholder residency requirements.
-
Select a state of incorporation: A company can be incorporated in any of the 50 states. Many businesses choose to incorporate in states like Delaware for its well-established corporate law and business-friendly courts, even if their primary operations are elsewhere. The choice of state will dictate formation costs, annual fees, and corporate governance rules.
-
Appoint a registered agent: Every state requires corporations and LLCs to have a registered agent with a physical address in the state of incorporation. This agent is responsible for receiving official legal documents and government correspondence on behalf of the company.
-
File formation documents: To legally create the subsidiary, you must file formation documents—typically called Articles of Incorporation for a C-Corp or Articles of Organization for an LLC—with the Secretary of State in your chosen state. This step also involves formally registering your business name.
-
Obtain a Federal Employer Identification Number (EIN): After incorporation, the subsidiary must apply to the Internal Revenue Service (IRS) for an EIN. This nine-digit number is essential for paying federal taxes, hiring employees, and opening a bank account. For companies without a U.S.-based responsible party, obtaining an EIN can take several weeks as the application must be submitted by mail or fax.
-
Open a U.S. corporate bank account: Opening a business bank account is a critical but often challenging step. U.S. banks have strict “Know Your Customer” (KYC) regulations that may require a company director to visit a branch in person to complete the paperwork.
Ongoing compliance for U.S. subsidiaries
Setting up the subsidiary is only the beginning. Ongoing compliance is crucial to maintain good legal standing and protect the parent company’s liability shield. Key obligations include:
-
Annual reports and franchise taxes: Most states require subsidiaries to file an annual report and pay an annual franchise tax or filing fee to remain active. Deadlines and costs vary significantly by state.
-
Federal, state, and local taxes: Subsidiaries are subject to U.S. corporate income taxes at the federal level and, in most cases, at the state level. They must also manage payroll taxes, sales taxes, and property taxes where applicable.
-
Corporate formalities: Corporations must adhere to internal governance rules, such as holding regular board meetings, keeping minutes, and maintaining corporate bylaws to ensure the legal separation between the subsidiary and its parent company.
Why establish a U.S. subsidiary?
The primary benefit of creating a subsidiary is establishing a distinct legal entity in the United States. This structure provides limited liability, meaning the parent company’s assets are generally shielded from the debts and legal obligations of the U.S. subsidiary. It also creates a permanent, credible presence in the U.S. market, which can be beneficial for building relationships with customers and partners.
However, the cost, time, and resources required to manage this process are substantial. Companies must engage U.S. legal and accounting experts to navigate the complexities, making it a resource-intensive undertaking.

FAQs
When do you need to foreign qualify in another state after forming?
State laws mandate foreign qualification when your U.S. subsidiary conducts business outside its formation state. Operating an office, hiring talent, or conducting recurring local operations triggers this process. Confirm state rules before signing contracts or hiring talent.
How do foreign-owned U.S. subsidiaries apply for an EIN using IRS Form SS-4?
Submit IRS Form SS-4 with your entity's legal name, formation jurisdiction, U.S. mailing address, tax classification, and application reason. List a designated responsible party. Foreign applicants ineligible for online application must submit via the IRS international fax or mail process.
Who can be the Form SS-4 responsible party for a foreign-owned U.S. subsidiary?
The IRS Form SS-4 responsible party must be an individual who controls or owns the entity. A non-U.S. individual can serve in this role. Do not list nominees. If the individual lacks an SSN or ITIN, follow the Line 7b instructions rather than creating an identifier.
What are the BOI reporting considerations for foreign-owned subsidiaries?
Under FinCEN rules, entities created in the U.S. maintain an exemption from federal beneficial ownership information (BOI) reporting as domestic reporting companies. This exemption applies even to foreign-owned Delaware subsidiaries. Entities formed under foreign law that register in a U.S. state remain foreign reporting companies unless an exemption applies. Always verify state-level transparency filings.
What are the steps to set up a U.S. subsidiary for a foreign parent?
Select the state and entity type, clear your name, and appoint a registered agent. File formation documents, adopt governance rules, and issue ownership records to the foreign parent. Obtain an EIN, open a bank account, and fund the subsidiary. Register for local tax accounts, foreign qualify where hiring talent, secure licenses, set up payroll, and track annual filing deadlines.
Which U.S. state should a foreign parent choose to form a subsidiary?
Form your subsidiary where your talent and primary operations reside to avoid duplicate registration, agent fees, and franchise taxes. Delaware fits companies seeking complex equity structures or established corporate case law. Forming in Delaware does not exempt your business from local state taxes and employment laws where talent works.
What corporate records should a U.S. subsidiary maintain after forming?
Maintain your formation filings, bylaws, board consents, equity ledgers, EIN confirmation, tax returns, and employment records. Keep parent and subsidiary bank accounts, contracts, and decisions completely separate to preserve your legal liability protection.
