Start here if you are outside the United States and need a practical US company setup path. Use this as a sequence, not a shopping list. The right provider depends on entity fit, address roles, EIN context, banking documents, platform requirements, and compliance workload.
Separate each role before choosing providers or submitting applications.
-
01
Confirm entity fit
Choose LLC/C-Corp, state, ownership, and tax context before paying a provider.
Output: filing path and company name. -
02
Assign registered agent
Use the agent for state notices and service of process.
Do not treat it as routine mail handling. -
03
Separate address fields
Decide which field needs agent, mailing, business, or owner residential address.
Output: address map before applications. -
04
Prepare EIN context
Collect responsible-party details, SS-4 facts, and formation records.
EIN helps setup; it is not approval. -
05
Apply for banking/payment tools
Submit KYB, owner ID, website, business model, and address proof where required.
Eligibility is provider-specific. -
06
Maintain compliance
Track annual reports, bookkeeping, tax forms, and renewal dates.
Formation is not the finish line.
- Keep entity, address, EIN, banking, and compliance as separate workstreams.
- Do not buy a package because it says "all-in-one" without checking what each step actually covers.
Use this setup sequence
- Confirm whether a US LLC path fits your situation.
- Separate the registered-agent role from mail and business address roles.
- Compare registered agent, virtual mailbox, and virtual office use cases.
- Prepare the EIN context before banking or platform applications.
- Prepare documents for banking and fintech review.
- Check Stripe requirements before assuming a US company is enough.

Editorial guardrails
US Founder Stack is educational. We do not give legal, tax, accounting, banking, or investment advice, and we do not promise approval from the IRS, banks, fintechs, Stripe, PayPal, marketplaces, or any provider.
