Firstbase

Start and administer a US company with compliance, accounting, and tax services

Meet Firstbase

Firstbase provides company formation and back-office services for US businesses. Founders can submit incorporation information online for filing and expert review, or bring an existing business onto the platform. Business address and mailroom services organize incoming correspondence, while registered-agent and filing services cover recurring company administration.

Accounting tools and bookkeeping services prepare financial records for tax and investor reporting. Tax services support corporate and personal returns, and compliance products include annual reports and franchise tax filings. Firstbase One combines several back-office products in a package. A founder can use these services to manage records and filing tasks after formation as the business operates.
