1. Choose your structure: LLC or C-Corporation
An LLC is flexible and pass-through by default — good for operating businesses and single owners. A C-Corporation (usually Delaware) is what venture investors expect and supports stock options and preferred rounds. Non-residents cannot hold S-Corporation shares, so that route is off the table for most foreign founders.
2. Pick the right state of formation
Form where you actually operate unless you have a specific reason not to. Delaware suits companies raising institutional capital; Wyoming and Florida are common low-cost choices. Forming out of state still requires a foreign qualification in every state where you have employees, offices, or substantial activity — that is where duplicate cost hides.
3. Appoint a registered agent and file formation documents
Every entity needs a registered agent with a physical address in the state of formation. You then file Articles of Organization (LLC) or Articles of Incorporation (corporation) with the Secretary of State. Approval is often same-day to two weeks depending on the state and filing tier.
4. Obtain your EIN from the IRS
The Employer Identification Number is your federal tax ID and a prerequisite for banking, payroll, and most filings. Applicants with a US SSN or ITIN can apply online; foreign owners without one apply on Form SS-4 by fax or mail, which takes longer. See the dedicated USA EIN application guide for the full process, and plan for it in your launch timeline.
5. Adopt governing documents and issue equity
Adopt an operating agreement (LLC) or bylaws plus board and stockholder consents (corporation), issue shares or membership interests, and maintain a cap table. Founders on vesting schedules should consider an 83(b) election within 30 days of the grant — the deadline is strict.
6. Meet federal reporting: BOI, tax elections and withholding
Reporting companies file beneficial ownership information under the Corporate Transparency Act where applicable. Foreign-owned single-member LLCs must file Form 5472 with a pro-forma 1120 annually. Payments to non-US persons may trigger withholding and W-8 documentation.
7. Register for state tax, licences and payroll
Register for sales tax where you have economic nexus (thresholds vary by state, commonly $100,000 in sales), for payroll withholding and unemployment insurance in each employee's state, and for any local business licences. Misclassifying contractors as employees is one of the most common — and expensive — early mistakes.
8. Open banking and keep annual filings current
US banks require formation documents, the EIN letter, governing documents, and KYC on every beneficial owner; foreign ownership means enhanced due diligence. After launch, file annual reports and franchise tax in each registered state, keep the registered agent current, and maintain minutes and statutory records.
