What Is a Registered Agent (and Why Your US LLC Needs One)?
Short answer: a registered agent is a person or company with a physical address in your LLC's state that receives official legal and government mail on the company's behalf. Every US LLC is legally required to have one — and for non-US founders it's essential, because you need a reliable US address you don't personally have.
What a registered agent actually does
- Receives legal documents (e.g., lawsuit notices) and state correspondence on behalf of your LLC.
- Provides a physical street address in the state of formation (not a PO box).
- Forwards/scans what they receive so you don't miss anything important.
Why non-US founders especially need one
You can't be your own registered agent without a physical address in the formation state — which most non-residents don't have. A registered-agent service solves that, and keeps your personal address off public records.
What to look for
- Reliability — they must actually forward/scan your mail promptly (missing a legal or state notice is costly).
- Online dashboard with document scanning.
- Reasonable annual fee (this is a recurring cost).
- Bonus: services that also help with formation + compliance reminders.
Where it fits in your setup
A registered agent is step one of running a compliant US LLC, alongside your EIN and annual Form 5472. The agent handles the mail; FounderFi helps you stay on top of the filings and deadlines that follow.
