How much does Firstbase cost?

Firstbase leads with a one-time $399 formation fee, which is a cleaner model than a recurring formation subscription. That fee (plus the state's own filing fee) covers setting up your US company. The costs that recur are separate line items: registered agent service from $299 per state per year, the Mailroom virtual mailbox from $35 per month, and tax filing services at around $1,799 per year depending on your structure.

Because the formation is one-time, the sticker looks lower than services that bundle everything into an annual price, but the real comparison is the multi-year total. On a three-year basis, a Firstbase founder using tax filing spends roughly $3,276 all in, which is competitive with the market and cheaper than some all-in-one annual bundles once you add up their recurring fees.

Firstbase advertises no setup fees or hidden charges, and its plans include automatic updates when tax rates or filing requirements change, which reduces the risk of missing a compliance change. Still, budget for the recurring pieces (agent, mailbox, taxes) rather than only the $399, since those are where ongoing cost lives.

This is general information, not tax or legal advice. State fees and filing costs vary by state and structure, so confirm the current figures for your situation with a qualified professional.
