Do you work with law firms?

Yes — we have specific features built for law firms managing multiple client entities. Our multi-client dashboard lets firms view and manage all client entities, deadlines, and filings from one platform. See our Law Firms page for details.

What is a registered agent and why do I need one?

A registered agent is a person or entity designated to receive official government and legal documents on behalf of your business — including service of process, state notices, and annual report reminders. Every business entity registered in a state is legally required to maintain a registered agent with a physical address in that state.

How does SingleFile handle CTA / BOI reporting?

We help you determine whether your entities are required to file BOI reports with FinCEN, identify beneficial owners, prepare accurate reports, and manage update filings when ownership changes. Under the current Interim Final Rule (March 2025), only foreign reporting companies are required to file. See our CTA Reporting page for current status.

Is my data secure?

SingleFile is SOC 2 Type II certified. We handle sensitive entity and beneficial ownership data with enterprise-grade security controls, encryption at rest and in transit, and strict access controls.
