Get answers to the most common questions about U.S. company formation, EIN/ITIN, and our services.
Yes! There are no citizenship or residency requirements to form an LLC or corporation in the United States. You can form a U.S. company from anywhere in the world. At USBase, we specialize in helping international entrepreneurs set up their U.S. businesses remotely — entirely online.
An EIN (Employer Identification Number) is a federal tax ID number issued by the IRS. It's required to open a U.S. business bank account, hire employees, file taxes, and set up payment processors like Stripe or PayPal. Virtually every U.S. business needs one. We obtain EINs on behalf of our clients — typically within 1–2 business days.
An ITIN (Individual Taxpayer Identification Number) is issued by the IRS to individuals who are required to have a U.S. taxpayer number but are not eligible for a Social Security Number (SSN). Non-U.S. residents who earn U.S.-source income, own U.S. businesses, or file U.S. tax returns typically need an ITIN. As an IRS Authorized Acceptance Agent, we certify your documents and submit your application directly to the IRS.
The most popular states for non-residents are Delaware, Wyoming, and New Mexico — each offering distinct advantages. Delaware is preferred for venture-backed startups and corporations due to its well-established corporate law. Wyoming offers strong privacy protections and low fees, making it ideal for LLCs. New Mexico offers affordable annual costs and good privacy. Our experts will recommend the best state based on your specific business goals.
No, you don't need a personal U.S. address. However, your company is legally required to have a Registered Agent with a physical U.S. address in the state of formation. USBase provides Registered Agent service in all 50 states, which satisfies this requirement and ensures you never miss important legal or government correspondence.
Processing times vary by state, but most LLC formations are completed in 3–7 business days. Some states like New Mexico and Wyoming process formations in as little as 1–2 business days. We also offer expedited processing options for most states. Once formed, we'll have your EIN and documents ready for you promptly.
Most U.S. companies need to file an Annual Report and pay a renewal fee to their state each year. Depending on your business activity and structure, you may also need to file federal and state tax returns. Some states also have franchise tax requirements. USBase offers complete ongoing compliance management — we track your deadlines and handle all filings for you.
Yes. USBase is an IRS Authorized Acceptance Agent, which means we are officially authorized by the IRS to assist individuals and entities in completing their ITIN applications. We certify identity documents, verify their authenticity, and submit applications directly to the IRS — which significantly speeds up processing and reduces the risk of rejection compared to self-filing.
