What is Firstbase?

Firstbase is a service for forming and running a US company. It has two main products: Start, which handles formation, and Firstbase One, which adds the tools you need to stay compliant afterwards.

It is built for founders, including those living outside the United States, who need a legal entity, a US address and ongoing filings without hiring several providers.

Key features

• Company formation – set up in Delaware or Wyoming, with expedited Tax ID (EIN) setup and essential documents such as bylaws and a stock purchase agreement.
• Registered agent – an Autopilot product with compliance reminders and state annual report filings.
• Mailroom – a physical US business address with a virtual mailbox, mail scans and digital storage.
• Accounting – AI-assisted, human-managed bookkeeping with a dedicated dashboard and live chat with a bookkeeper.
• Tax filing – federal and state returns for LLCs and C-Corps, including packages for non-US-owned single-member LLCs.
• Sales tax – nexus monitoring and automated filings for startups and larger companies.

Is Firstbase worth it?

Pros

• Formation, agent, mailbox, accounting and tax filing under one roof.
• Works for founders based outside the US.
• The bundle can cost less than buying products separately.

Cons

• The registered agent is billed per state each year.
• State fees and taxes are paid on top.
• Accounting and tax filing carry premium prices.
